Desarrollo y mejora de los modelos meteorológicos de predicción numérica para su utilización en el campo de las energías renovables. Generación de una base de datos de alta resolución espacial y temporal del recurso solar directo en la provincia de Jaén.
Along the next years, the electric generation from renewables will experience a strong growth in Spain, even greater than the growth in the last five years. This is an unavoidable fact since we have to accomplish with the EU's commitments on the electrical production from renewable energies and reduction of the greenhouse gases by 2020. Particularly, for the solar energy, most of the generation will come from concentrating solar systems, where Spain is currently the first worldwide producer. However, the atmospheric fluctuations of the solar resource cause fluctuations on the production systems which distort and unbalance the electric distribution through the grid by feeding too much resource in some sites while in other there is a deficit. The weather models may be helpful in two different manners in the mitigation of this issue: (i) by allowing computing precise and reliable data bases with high spatial and temporal resolution to find out the best sitting and sizing of the solar systems according to the local variability of the resource and to support the development of the current concentrating photovoltaic systems; (ii) by forecasting the solar resource for improved planning and operation strategies of the production plants. This proposal aims to improve the current numerical weather prediction models so that they can be used in renewable energy applications. As a final result, it is intended to generate a 10-years-length, high spatial and temporal resolution data base of the direct normal solar radiation in the province of Jaén. It will be essential to support the development of the concentrating photovoltaic systems that currently are being conducted as part of the activities in the future Centre of Advanced Studies in Energy and Environment in the University of Jaén.


Positron Subsidiary Files Patent Applications for Proprietary Radiation Detection Technologies To Be Used in PET Scanners and Homeland Security Devices
Friday March 2, 4:01 pm ET
HOUSTON--(BUSINESS WIRE)--Positron Corporation (OTCBB: POSC - News; the Company), a developer and manufacturer of Positron Emission Tomography (PET) medical devices, announced today that through its subsidiary developed intellectual property in the field of solid state photo detection and its applications. The Company has four patents pending covering the design and construction of medical diagnostic molecular imaging scanners and radiation detection scanners for homeland security with its new class of solid state photodetectors. The compact, low-cost photodetectors have increased sensitivity that can detect a single quantum of light and may significantly reduce the cost of future PET scanners while improving spatial resolution and portability. Solid state photodetectors are the key component in the development of compact organ-specific PET scanners and effective radiation detection devices for monitoring of radiation proliferation by parties unfriendly to national security interests. The Company's research and development projects were conducted at facilities across North America with the participation of a team of collaborating scientists directed by Dr. Irving Weinberg.

The Making of Automated Terrariums
It’s been our dream to do this for a while now, a lot of wasted electronics parts, a lot of Youtube videos and help from a electrical engineer got us here. Our old terrarium were dependant on a window to give the plants light. Meaning it was bound to be in a specific location. To get around this, we decided to create a terrarium that can be placed anywhere,
Adequate lighting is provided by a 10w LED, which is strong enough to mimic sunlight. Air is moved through a small fan, which also keeps the LED cool. A safe 12v DC current moves through wires that are cleverly hidden inside the solder joins to preserve aesthetic.
These automatic terrariums are still under development. We are currently in phase one, where we use a on off switch to control the terrarium. Phase two involves the inclusion of an Arduino board, which will self-program the terrarium, enabling it to function entirely on its own. A little bit more programing and midnight coffee hopefully will get us there.

Bottlenecks are splitted by GPUs and CPUs.
The goal of our calculator is to provide easier creation of computer configurations.
Bottleneck is a kind of hardware limitation in your computer. A bottleneck occurs when the capacity of an application or a computer system is severely limited by a single component. Components that often bottleneck are graphic card, processor and HDD. Bottlenecks affect microprocessor performance by slowing down the flow of information back and forth from the CPU and the memory. If all of the components of a system are not able to feed the same amount of data at the same speed, a delay is created. You system is specified by your weakest component, not the fastest one. For example, a 2GB processor will be severely bottlenecked by an 800MB memory bandwidth.
Everyone thoughts that the most important component for gaming is GPU. You have HIGH END GPU and you still have low FPS rate? Probably you have to weak CPU for that kind of graphic card. All you components needs to be in equal rank.

When “Back to the Future” first hit the silver screen in 1985, it took audiences on a thrilling ride through time, mixing science fiction with humor and adventure. Little did the creators of the film, Robert Zemeckis and Bob Gale, know that their vision of the future, set in 2015, would be examined and compared to the real 2023, almost four decades later. While we’re still waiting for hoverboards and flying cars, there are some eerie similarities between the movie’s portrayal of 2015 and the world we live in today.
The film introduced us to the concept of wearable technology, with Marty’s son wearing a pair of smart glasses during the 2015 sequence. Today, we have smartwatches, augmented reality glasses, and other wearable devices that can provide information at our fingertips. While we haven’t quite reached the level of sophistication seen in the movie, it’s clear that “Back to the Future” was ahead of its time in predicting the direction of technology.
In the movie, Marty is easily identified by a retinal scan at his home in 2015. Today, we commonly use biometric technology for security and identification purposes, such as fingerprint and facial recognition on our smartphones. While we might not be using retinal scans at home just yet, biometric authentication is certainly a reality in our lives.
Remember Marty’s self-lacing Nike sneakers in the movie? Well, they’re no longer a thing of the future. Nike actually released a limited edition of self-lacing shoes in 2016, known as the Nike Mag, inspired by the film. Though they aren’t widely available yet, the fact that they exist at all is a testament to the movie’s accurate predictions.
Drones and Flying Cameras
The movie featured a drone-like device capturing the arrest of Biff Tannen. In 2023, drones are everywhere, from capturing stunning aerial shots in film and photography to being used in various industries for inspections and deliveries. While they might not be as comical as the movie’s version, the prediction of drones being a part of our everyday lives was quite accurate.
“Back to the Future” showcased flat-screen televisions as commonplace in homes, a far cry from the bulky CRT televisions of the 1980s. By 2023, flat-screen TVs have become the standard, with sleek designs and advanced display technology. The film’s vision of home entertainment has certainly become a reality.
Video Calls and Communication
In “Back to the Future Part II,” Marty McFly encounters a future in which video calls are the norm. Fast forward to 2023, and video calls are not only commonplace, but they’re also an essential part of our daily lives. Thanks to technology like Zoom and FaceTime, we can easily communicate with anyone around the world through video calls, just as the film predicted.
Video Games Without Controllers
Marty McFly Jr. plays a video game in the movie without using a controller. In reality, technology has evolved to include gesture-based and motion-sensing gaming systems like the Xbox Kinect and PlayStation Move, where players can interact with games using their own movements. While we may not be at the level of gaming seen in the film, the concept of controller-free gaming is certainly present.
“Back to the Future” showed holographic advertisements and entertainment in the town square of Hill Valley. In our world today, we’ve seen holographic displays used in marketing and entertainment, albeit on a smaller scale. The concept of holographic advertising is slowly becoming a reality.
“Back to the Future” featured voice-activated devices that respond to vocal commands. Today, we have virtual assistants like Siri, Alexa, and Google Assistant that can answer questions, control smart home devices, and perform various tasks through voice commands. The film’s portrayal of voice-activated technology was remarkably prescient.
In the movie, Marty uses his thumbprint to make a payment at a Café 80s. In 2023, biometric payment methods like Apple Pay and fingerprint authentication are increasingly common, making transactions quicker and more secure. The film’s prediction of biometric payment was not too far from reality.
While “Back to the Future” made some impressive predictions, it’s essential to remember that it’s still a work of science fiction, and not everything portrayed in the film has come to pass. We’re not zipping around in flying cars, and hoverboards are still not a mode of transportation. The movie’s depiction of time travel remains firmly in the realm of fantasy.
Nonetheless, the film’s vision of 2015, as seen from the perspective of 1985, was remarkably accurate in predicting certain technological advancements that have become an integral part of our lives in 2023. It’s a testament to the creativity and foresight of the filmmakers, who, in their quest to entertain and amaze, inadvertently offered a glimpse into the future.
“Back to the Future” may not have been entirely accurate in predicting 2015 or 2023, but it undeniably got many things right when it comes to technological advancements. As we continue to make strides in the world of technology, it’s fascinating to look back at a movie that, in its own quirky way, provided a window into the future. So, prepare to be amazed at how ‘Back to the Future’ predicted 2023 with surprising accuracy and continues to capture our imaginations. Who knows what other aspects of the film’s vision might become reality in the years to come?

E1 is a distributed operating system project, based on the following concepts:
- object replication
- component model support
To provide applications with transparent access to all resources of computer network, state and functionality of operating system components and application software are encapsulated by distributed objects.
Reliability and efficiency of access are achieved by means of object replication. In E1 a complete or partial copy of a distributed object's state is placed in each node where the object is used. The state of an object is synchronized (replicated) among nodes. For each object the most efficient replication algorithm can be selected on the basis of object's semantics. In most cases such algorithm can be found among existing replication strategies. Alternatively, it can be designed specifically for the given type of objects, which allows to maximize the efficiency of access by taking type-specific properties into account. >>
Following the current trend towards component software, E1 provides support for component-oriented programming. Development and use of components require a component model, defining a set of services, interfaces and conventions, all of which constitute the execution and communication environment for components. Current component models are usually implemented as middleware systems. In contrast, E1 implements component model by extending the distributed object model with component-oriented services and tools, thus avoiding the use of additional software layer. Besides being highly efficient, such architecture simplifies the development and use of components, since in E1 distributed objects (or components) are first-class citizen, like files in UNIX. The E1 component model provides services for object protection, global object naming, dynamic class loading, garbage collection, as well as component development tools like IDL compiler and replication strategy compiler. >>
Persistence is the ability of the objects to exist for unlimited time, irrespectively of whether a system functions continuously. For this purpose a copy of an object is maintained in nonvolatile storage. The stored object state is always correct, even in the face of hardware failures.
Among other E1 features are:
- microkernel-based architecture;
- a single virtual 64-bit address space;
- execution model, based on migrating threads;


“Music on a Long Thin Wire” is constructed as follows: the wire is extended across a large room, clamped to tables at both ends. The ends of the wire are connected to the loudspeaker terminals of a power amplifier placed under one of the tables. A sine wave oscillator is connected to the amplifier. A magnet straddles the wire at one end. Wooden bridges are inserted under the wire at both ends to which contact microphones are imbedded, routed to a stereo sound system. The microphones pick up the vibrations that the wire imparts to the bridges and are sent through the playback system. By varying the frequency and loudness of the oscillator, a rich variety of slides, frequency shifts, audible beats and other sonic phenomena may be produced.”

Zapraszamy na seminarium ZTS w dniu 22 czerwca 2022 r. o godzinie 14:15 w sali seminaryjnej IRiTM w (428) w Gmachu WEiTI. Referat pt. „Investigation of frequency characteristics of hybrid meander structures” wygłosi Diana Belova-Plonienė z Vilniaus Gedimino technikos universitetas – VILNIUS TECH.
Meander structures are often used in microwave devices because of small dimensions and positive features. Meander structures allow reducing the size of the microwave devices while keeping the same operational characteristics. The features of the meander structures like passband, characteristic impedance, delay time and others could be adjusted by using different materials or structures of the meander conductor.
The research of construction of hybrid meander structures will be discussed in this presentation. The hybrid meander structure is formed by using the 3D shape of connecting electrodes. The shape of the connecting electrodes of the meander conductor has a significant impact to the operation of the meander structure. The results of S parameters and delay time of hybrid meander structure will be compared with traditional planar meander structure. The influence of additional shields and different grounding positions to the pass-band will be also discussed. The presented results are obtained by using computer based simulation with commercial software packages and also by physical experiment.
Intelligent methods like artificial neural networks have a significant potential to be used in the analysis and synthesis of microwave devices. Therefore, the analysis of the hybrid meander structures using intelligent methods based on the feedforward backpropagation multilayer perceptron networks will be also discussed.

The first Laptop networks were being devoted Specific-objective techniques for example SABRE (an airline reservation program) and AUTODIN I (a defense command-and-control program), each created and implemented during the late nineteen fifties and early sixties. By the early sixties Laptop makers experienced begun to utilize semiconductor technology in business merchandise, and each typical batch-processing and time-sharing techniques were being in place in many huge, technologically Superior companies. Time-sharing techniques permitted a pc’s resources being shared in swift succession with various users, biking in the queue of users so rapidly that the computer appeared focused on each person’s duties despite the existence of numerous Other folks accessing the program “at the same time.” This led into the Idea of sharing Laptop resources (known as host pcs or just hosts) above a complete community. Host-to-host interactions were being envisioned, in conjunction with usage of specialized resources (for example supercomputers and mass storage techniques) and interactive entry by remote users into the computational powers of your time-sharing techniques Found in other places. These Strategies were being to start with realized in ARPANET, which set up the main host-to-host community relationship on October 29, 1969. It had been made by the Sophisticated Study Initiatives Company (ARPA) in the U.S. Office of Defense. ARPANET was among the to start with standard-objective Laptop networks. It linked time-sharing pcs at authorities-supported study internet sites, principally universities in The us, and it soon turned a important bit of infrastructure for the computer science study Neighborhood in The us. Instruments and purposes—including the simple mail transfer protocol (SMTP, commonly often called e-mail), for sending shorter messages, and the file transfer protocol (FTP), for for a longer period transmissions—rapidly emerged. As a way to achieve Value-helpful interactive communications in between pcs, which typically communicate in short bursts of knowledge, ARPANET utilized the new technology of packet switching. Packet switching usually takes huge messages (or chunks of Laptop facts) and breaks them into lesser, manageable parts (often called packets) that could travel independently above any offered circuit into the concentrate on location, exactly where the parts are reassembled. As a result, contrary to common voice communications, packet switching isn’t going to need a solitary devoted circuit in between each set of users. Business packet networks were being launched during the nineteen seventies, but these were being created principally to supply efficient usage of remote pcs by devoted terminals. Briefly, they changed long-distance modem connections by less-highly-priced “Digital” circuits above packet networks. In The us, Telenet and Tymnet were being two these kinds of packet networks. Neither supported host-to-host communications; during the nineteen seventies this was nonetheless the province in the study networks, and it could stay so for many years. DARPA (Defense Sophisticated Study Initiatives Company; previously ARPA) supported initiatives for ground-based mostly and satellite-based mostly packet networks. The ground-based mostly packet radio program offered mobile usage of computing resources, though the packet satellite community linked The us with several European nations around the world and enabled connections with widely dispersed and remote regions. Along with the introduction of packet radio, connecting a mobile terminal to a pc community turned possible. Nevertheless, time-sharing techniques were being then nonetheless too huge, unwieldy, and costly being mobile or simply to exist outdoors a local climate-managed computing surroundings. A robust drive So existed to connect the packet radio community to ARPANET to be able to allow for mobile users with simple terminals to entry the time-sharing techniques for which that they had authorization. Likewise, the packet satellite community was used by DARPA to website link The us with satellite terminals serving the uk, Norway, Germany, and Italy. These terminals, nevertheless, needed to be linked to other networks in European nations around the world to be able to reach the close users. As a result arose the need to hook up the packet satellite Web, together with the packet radio Web, with other networks. Basis of the world wide web The world wide web resulted from the trouble to connect various study networks in The us and Europe. Initially, DARPA set up a method to research the interconnection of “heterogeneous networks.” This method, known as Internetting, was based on the freshly launched notion of open up architecture networking, during which networks with described standard interfaces could well be interconnected by “gateways.” A Performing demonstration in the notion was planned. To ensure that the notion to work, a whole new protocol needed to be created and developed; without a doubt, a program architecture was also demanded. In 1974 Vinton Cerf, then at Stanford University in California, which author, then at DARPA, collaborated with a paper that to start with explained this kind of protocol and program architecture—particularly, the transmission control protocol (TCP), which enabled different types of equipment on networks all around the world to route and assemble facts packets. TCP, which initially incorporated the world wide web protocol (IP), a worldwide addressing system that permitted routers to have facts packets to their top location, formed the TCP/IP standard, which was adopted by the U.S. Office of Defense in 1980. By the early nineteen eighties the “open up architecture” in the TCP/IP approach was adopted and endorsed by many other researchers and finally by technologists and businessmen all over the world. By the nineteen eighties other U.S. governmental bodies were being greatly involved with networking, such as the Nationwide Science Basis (NSF), the Office of Electrical power, and the Nationwide Aeronautics and Place Administration (NASA). Even though DARPA experienced performed a seminal job in developing a modest-scale version of the world wide web between its researchers, NSF labored with DARPA to grow usage of your complete scientific and academic Neighborhood and to produce TCP/IP the standard in all federally supported study networks. In 1985–86 NSF funded the main 5 supercomputing centres—at Princeton University, the University of Pittsburgh, the University of California, San Diego, the University of Illinois, and Cornell University. During the nineteen eighties NSF also funded the event and operation in the NSFNET, a national “backbone” community to connect these centres. By the late nineteen eighties the community was running at many bits per second. NSF also funded various nonprofit neighborhood and regional networks to connect other users into the NSFNET. A number of business networks also started during the late nineteen eighties; these were being soon joined by Other folks, and the Business World-wide-web Exchange (CIX) was formed to allow transit website traffic in between business networks that otherwise would not are permitted around the NSFNET backbone. In 1995, immediately after comprehensive overview of the problem, NSF decided that guidance in the NSFNET infrastructure was no longer demanded, considering the fact that many business companies were being now eager and in a position to meet the requirements in the study Neighborhood, and its guidance was withdrawn. In the meantime, NSF experienced fostered a competitive selection of commercial World-wide-web backbones linked to each other through so-known as community entry details (NAPs).

LuminAID Solar-Powered Inflatable Light
Have you ever seen this?
It’s a LuminAID Solar-Powered Inflatable Light. We came across this little gem just a few weeks ago and have been intrigued ever since. It’s a light weight bag, powered by the sun can be a great light for your boat. Although the advertise that these are not just nautical instruments and can be used any where, at any time and for any reason, we like the idea of putting one on the deck of the boat. If needed you can probably even strap one to the bow of your boat as a sort of temporary light on your boat used for night time sailing.
Here are the Specifics From Their Website:
3 ounces / 85 grams
12.5″ L x 8.5″ W (when deflated)
- Storage and Battery Function:
The LuminAID can hold a full charge for ~4 months. Before storing for an extended period of time, it is best to make sure the battery is fully charged. We also recommend charging every 1-2 months to keep the battery at optimum condition.
How it Works
Charge in sun for 5 hours for up to 8 hours of LED light.
Inflate using valve. The inflation diffuses light like a lantern
and protects eyes from any glare from the LED light source.
Illuminate with power switch once for LOW and twice for HIGH.
The LuminAID is water-resistant and can float.
It all started when Anna Stork and Andrea Sreshta met while studying architecture and design in graduate school. Sharing a an interest in solar lighting technology and a passion for helping solve problems on the global scale they designed the LuminAID. In 2010 earthquake disaster in Haiti, the LuminAID was created to help fulfill the basic need for light when no power was working. Since then, they have come to the relief in many natural disasters in the U.S. and around the world. For the same space that it takes to pack 8 regular-sized flashlights, you can pack 50 inflatable Luminaids. Not only that, but for every LuminAID you buy in their program, they will donate one to their Give A Light Project to help build up the supply for the next natural disaster. Their goal is to make light more sustainable, available and affordable for all. Their cool invention has now been featured in Men’s Journal, on CNN, The Huffington Post, Forbes, BBC, Fast Company, The White House, WiReD and more.
For More Information on the LuminAID Solar-Powered Inflatable Light CLICK HERE to visit their website www.LuminaidLab.com. So, if you need an extra light for your deck or cabin, or next time your going camping or for disaster relief, think about getting a LuminAID and give back. Here’s a short video that demonstrates how it all works.


Typically, electric solder contains rosin core flux; plumbing solder uses an acid-based flux. Therefore, it's not a good idea to use plumbing solder for electrical connections because the acid in the flux can damage the wiring and cause a connection failure. Electric welding has a lower melting point (around 360˚F), while welding used in plumbing has higher melting points, generally above 400˚F. This is why electric welding can be performed with a soldering iron, while many welding pipes use a welding torch gas for heating metals.
Electric welds also tend to be smaller gauge, suggesting that they melt faster, rather than pipe welding, which is generally thicker gauge and requires more heat to melt. Plumbing welding comes in a larger diameter coil of wire than electric welding, making it more difficult to handle than electric welding. This alone is a good reason not to use plumbing solder for electrical work, but it can also damage electrical conductors. Resin-core electrical welding, on the other hand, is not strong enough to withstand pressurized water.
All types are still sold, so make sure the product says lead free if the solder is intended for household plumbing. However, that corrosive acid flux will quickly degrade wiring if plumbing solder is mistakenly used for electronics. The acid in the plumber's flux helps the solid-core solder form a tight bond, but it is corrosive, especially when subjected to the heating effects of electrical resistance. The solder you use for plumbing work usually has a solid core, and for it to adhere, you must apply acid-based flux.
Soldering is an important component of both plumbing and electronics, but plumbing soldering and electric soldering are two very different substances. Using the wrong solder can lead to leaks in plumbing fixtures and failure of electrical connections. Due to the dangers of toxic lead in drinking water, local building codes now legally require the use of lead-free plumbing solder on all drinking water pipe connections that require soldering. Plumbing welding with high tensile strength makes pipe joints stronger, but melts at higher temperatures than softer electronic solder.


The release of the OnePlus 10 Pro left everyone with mixed feelings. While it was one of the strongest smartphones specifications-wise, it couldn’t go head-to-head with other brands like Samsung, Apple, and more. It mainly lacked good software, a camera, and the overall user experience.
But how does the OnePlus 11 holds itself against its predecessor? In this review, we will cover OnePlus 11 vs. OnePlus 10 Pro and see how much of an improvement did OnePlus make.
Is OnePlus 11 Worth The Upgrade?
Yes, OnePlus 11 is worth an upgrade compared to OnePlus 10 Pro if you’re looking for a great camera. The samples of the OnePlus 11 surprised many people, and many tech YouTubers have already tested the camera.
According to various tech camera comparisons like SuperSaf, the OnePlus 11 competes with the latest and greatest flagship smartphones like Apple iPhone 14 Pro.
So if you don’t like the washed-out camera from the OnePlus 10 Pro, you might find the upgrade more worth it. The price difference between the two models is minimal, and if you haven’t bought either device, then OnePlus 11 is easily a good pick.
However, you should question your purchase decision if you are already on a OnePlus 10 Pro. Changing phones is a subjective option. But if you want a complete comparison between the two devices, here’s everything you need to know.
Design: Which One Is More Attractive?
Even though the design seems to have changed, it’s more similar looking than ever. Both devices have Gorilla Glass Victus on the front with an aluminum frame. Moreover, the size and shape of both smartphones are similar, but OnePlus 11’s camera module seems more blend in with the back.
Instead of using a square camera design on the back, the OnePlus 11 has a circular camera and a larger unit than the OnePlus 10 Pro. Lastly, the camera module of the OnePlus 11 is built using a polished stainless steel platform.
Moreover, instead of a rough back, the OnePlus 11 has more of a polished and glossy surface with a diffusing layer. Finally, regarding water resistance, the OnePlus 10 Pro was rated as IP68 water and dust resistant. However, the 11 is only IP64. It’s disappointing to see the change, but that’s just like OnePlus.
Display: Which One Has Better Display?
OnePlus 11 and OnePlus 10 Pro have similar displays; 6.7 inch AMOLED with QHD+ resolution. Both devices have 1440 x 3216 with a 525ppi. Moreover, both devices also support a 120HZ LTPO display with a peak brightness of 1300nits.
If you look at the display side to side, you won’t be able to tell the difference. However, that doesn’t mean that OnePlus 10 Pro has a bad display. Both devices have an excellent display by today’s standards.
But one thing that 11 and 10 Pro suffer from is that the display doesn’t get plenty bright. Other competitors like Samsung and Apple have reached over 1500nits, substantially better than the OnePlus lineup.
When we talk about memory options, both phones have similar specs. OnePlus 10 Pro has a minimum RAM of 8 GB and goes up to 12 GB. However, OnePlus 11 have a maximum RAM option of 16 GB.
Both devices also have a maximum storage option of 512GB. But one area where OnePlus 11 takes the cake is the memory speed department. With the UFS 4.0 storage, you can expect the read and write speed to be blazing fast.
Even though OnePlus 10 Pro has 3.1 UFS storage, it’s not as fast as the 11.
Processors: Snapdragon 8 Gen 1 vs. Snapdragon 8 Gen 2
When we talk about processors, that’s where things change. The Snapdragon 8 Gen 2 has been successful in terms of thermal performance and power. Many modern phones come with 8 Gen 2, and its power is impressive.
However, in day-to-day usage, you won’t feel much performance difference. You feel the difference when you push both devices in Geekbench or Antutu Benchmark. The 8 Gen 2 is slightly faster than the 8 Gen 1, but the difference matters for tech-savvy people.
The processor difference seems miles away in the benchmark of the OnePlus 8 Gen 1 and 8 Gen 2. According to NanoReview, OnePlus 11 has a single-core performance of 1482 and a multicore performance of 4861. On the other hand, 10 Pro has a 976 score as a single core, while 3451 is a multi-core. That’s a big difference.
Camera: How Has OnePlus 11 Improved?
The camera is where things get interesting. OnePlus 11 has a triple camera, with the main lens being a 50MP, a 32MP telephoto, and a 48MP ultra-wide. The front cam is a wide-angle 16MP camera. However, when we compare the real-world performance of the two devices, it’s a huge improvement in OnePlus 11.
OnePlus 11 wins in nearly every department. From clarity, colors, and consistency, to night mode, selfies, and complex backgrounds, everything is right. OnePlus 10 Pro has issues with its front camera, where it overexposes the background.
But all in all, both phones have good cameras with OnePlus 11 being better.
Battery Life and Charging
OnePlus 10 Pro and 11 have great battery lives, and both are full-day phones. You can stress both phones in the real world with 5G, and you might still not kill them. Both phones come with a 5000mAh battery which is non-removable.
Talking about the charging side of things, the OnePlus 10 Pro can charge up to 100% in 32 minutes with its 80Watt Super VOOC fast charging. But here’s where things get interesting. The OnePlus 11 has 100Watt charging support, charging 1-100% in 25 minutes. If that isn’t impressive, I don’t know what is.
So Which One Should You Buy?
Both OnePlus 10 Pro and 11 are really good phones. The answer to which one you should buy depends on your goal. If you want a perfect flagship for a budget, then OnePlus 11 fits your budget.
However, if you have a lesser budget and still want flagship quality, then OnePlus 10 Pro should be your choice.


An introduction to GIS, GIS software, and its usesMaintaining data and delivering maps is a unique combination of science and art. The science is ensuring your data is accurate and up-to-date. The art comes into play as more and more software is created. New GIS software all solves a need, sometimes beautifully.
GIS data is shaping the world around us. It’s important we understand the history of Geographic Information Systems (GIS) so our technology can continue to grow and support the work we do. This month, we want to cover the evolution of GIS, what’s next with GIS technology, and explore several GIS software solutions for the modern cartographer.
The Evolution of GIS
From paper to desktop, to the cloud and now on mobile phones, GIS technology has evolved immensely over the centuries.
The use of paper maps expanded when blueprinting became available in the late 1800s, allowing maps to be reproduced as cyanotypes (cyan-blue colored copies) of their originals. Diazonium salt improved reproductions through a less-toxic process called whiteprinting. Finally, in the mid-1900s, and still in use today, xerography, the process of dry photostatic representation of an image, led to widespread use of maps.
The problem: maps were outdated as soon as they were created.
In the early 1980s, responding to the need to more easily update maps, the US Army Corps of Engineers commissioned new software: the Geographic Resources Analysis Support System (GRASS GIS) to aid in land management and environmental planning. At about the same time, Jack Dangermond used his former experience at Harvard and his company Environmental Systems Research Institute ‘ESRI’ to launch the first commercial GIS software.
By the mid-1990s, GRASS continued to be used by government agencies and some universities. In 1995, it became licensed as a fully open-source geospatial analytical tool as more and more institutions recognized the insights derived from working with geospatial data. However, open-source tools were not then widely supported by a large community of engineers, and, after a decade of use in the commercial industry, the graphic user interface (GUI) for ESRI’s products had outpaced GRASS in ease of use. ESRI expanded to overtake GRASS’s place in universities and government agencies to become the most adopted GIS desktop software.
Unfortunately, the cost of ESRI coupled with the lack of GRASS education left many geospatial users without good options for GIS software. This lack of access spawned a field of numerous micro GIS tools created to accomplish one of the hundreds of GIS tasks.
The landscape of uncoordinated GIS principles and standards created a very complicated professional workflow as users desired more and more functionality. Additionally, other companies (ie. AutoCad, Manifold, MapInfo) also sought to own a slice of the GIS market share and further added to the complexity of the GIS field.
In the early 2000s, the Open Source Geospatial Foundation (OSGEO) recognized the importance of geospatial technology to the greater public—that access to and the analysis of geospatial data should not be proprietary—and set out “to foster global adoption of open geospatial technology by being an inclusive software foundation devoted to an open philosophy and participatory community driven development.”
The OSGEO initiative defined standards of GIS file formats, data transfer protocols, and other works (including the maintenance of GRASS) with the intention to unify the geospatial field and to empower every-day desktop GIS users. OSGEO defined a set of standards still in use today.
Many of the GIS software options have intertwined development cycles. ESRI’s software products have always relied in part on GRASS’s software modules, and GRASS forms the core of QGIS. Likewise, ESRI and Google created a number of GIS principles that became integrated into the OSGEO standards; for example, OSGEO has recognized the shapefiles format and the ‘web-mercator’ worldwide map projection system that almost all web-based GIS software tools use to display maps today (EPSG:900913 - ‘Google’ spelled out in numbers), respectively.
By the 2010s, GIS technology really fractured into professional, desktop-based software, and simple, web-based software. ESRI had dominated the commercial GIS space but was too slow to keep pace with GIS expansion online. Users began to express stronger needs for updated maps and current aerial imagery. MapQuest, Google, and several other companies recognized this massive potential, and created systems to automate and distribute geographic information in a race to grab the online GIS market share.
Desktop-based software was soon found to have its disadvantages over web-based GIS software, including:
- Web-based GIS technology allows GIS techs to update fewer data sources, which means quicker updates and nearly instant distribution.
- Desktop-based GIS keeps one-off copies that are hard to maintain and distribute.
- The best GIS relies on a system of both the analytical power of a processor and the ability to distribute data to any number of users, forming a new generation of cloud-based GIS software solutions.
Today, GIS professionals are responding to cloud-based growth. We’re increasingly adopting OSGEO’s QGIS desktop-based software, an open-source alternative to ESRI, which combines the power of desktop-based analysis with an easy-to-use graphic interface. QGIS also leverages consistent standards and the ability to connect to online data sources without the burden of proprietary data formats.
What’s Next with GIS?
“There have been three big shifts in what people are asking online. The first was ‘what’–Google won that battle. The second question was ‘who,’ and Facebook won that. The next big question is ‘where’”.-Hans Peter Brondmo, 2013, Project Lead of machine learning at Google[x]
Growth in GIS technology is driven by our desire for real-time insights. The race for real-time, up-to-date maps spawned a wide array of companies seeking to grab and profit from current data. Having the most recent and accurate roads, trails, and navigation-based information has been the battleground of MapQuest, Google, Apple, and other GIS companies for years.
Within the aerial imagery arena—including photogrammetry-based elevation and image-recognition software to derive geographic and navigation intelligence—a number of new companies are finding ways to compete with the behemoths:
- Planet Labs launches hundreds of satellites each year- like spores- into Earth’s low-orbit to constantly capture updated aerial imagery;
- Digital Globe maintains larger satellites in a higher orbit to grab real-time imagery at visible and non-visible spectrums;
- Google (and its partner, Woolpert) use satellites and fixed-wing planes to keep their imagery current over the globe and highly populated areas; and
- Hexagon, uses a government contract to supply the USA Department of Agriculture with imagery of the contiguous 48 states under the NAIP program (free public access) and retains the highest resolution for commercial resale.
Exploring GIS Software OptionsA variety of GIS software options exist today to solve most user’s needs**, ranging from very simple options to very complex such as data analysis and manipulation.
Apps like Google Maps that have the most up-to-date information and basic editing are great for the public. And for approximately half of the professional market, the ease of ESRI’s complete integrated stack is worth the cost. For others, the flexibility, low cost of maintenance, and the capabilities of open source alternatives outweigh the technical acumen required for use like with QGIS. For certain industries, specific software provides advanced analytics and the option to create 3D data and models.
**Note, a complete geographic information system is also no longer a single piece of software, but a suite of products (a ‘stack’) that combine the intake, analysis, and distribution of the data- only select desktop and mobile options are described here.
So what software is available? Here’s a brief overview of the GIS software in use today
1) Free & Simple
Google made GIS available for widespread use with Google Earth. This GIS software works on most computers and phones and is easy to use. It gives you high quality imagery, road and information overlays, the ability to create your own content, and it’s free.
2) Open Source & Professional
If you learn QGIS, you are becoming part of an open source geographic information community that engineered and maintains a system capable of everything most people need. Though often confused with free- the software costs nothing- open source relies on a community of engineers who develop and implement new features.
3) Paid & Professional
ESRI’s option is a complete and largely proprietary geographic information system. As many universities use ESRI’s products in their GIS teachings, ESRI has become synonymous with GIS for a large number of young GIS professionals. Several other software options such as MapInfo or Manifold try to be competitors with ESRI by offering seamless integration with other application-specific workflows or at a lower cost.
4) Paid & Professional, Mining-Specific
Few GIS software options can handle advanced 3D modelling. For the mining community, 3D mine modelling is important in estimating volume calculations, developing mine plans, and other works of engineering. Mining software that can handle complex 3D graphic editing and display is relatively expensive and requires more advanced GIS experience.
The following tables list attributes of several common GIS software options. The list is incomplete- biased by our own use of GIS software over the last two decades- but represents a good foundation for the options available for mainstream, amateur, and professional GIS software users.
*Price: $ <100/yr, $$ 100-1000/yr, $$$ 1000+/yr
+ = Requires separate extension
Flat Maps Are A Thing of the Past (At Least with MineAR)The development cycles of desktop and web-based GIS didn’t evolve with great access or interaction with elevation data. As a result, GIS technology that leveraged elevation in combination with geographic information was wildly expensive as a professional tool (mainly for the mining, engineering, and architecture communities) and wildly popular when first introduced to the general public in the mid 2000s as Google Earth.
Today, many GIS software options now offer limited support for the visual interaction with elevation data (called 2.5D. It’s better than 2D, but not quite 3D).
True 3D options that provide visual interaction, especially with data extending below and above the Earth’s surface, remain in the domain of speciality software and have yet to break into mainstream mobile distribution (as shown by our chart above). That’s why we’ve created MineAR, to allow any GIS user the ability to visualize their data in real-space

Massachusetts Institute of Technology (MIT, USA) is one of those advanced centers that are applying new technologies to buildings.
In it, Oral Buyukozturk, Professor, Department of Civil and Environmental Engineering at the center, and his team have developed a computer model that interprets and gives meaning to environmental vibrations (for example, passing trucks near buildings or earthworks) for signs of damage or mechanical stress in buildings. The model can be used to monitor the ‘health’ of the continuously buildings.
When an earthquake or the passage of a truck rumbling make a building, vibrations can travel to the roof structure and generate transient tremors through intermediate floors and beams.
The new system allows, after events like these, immediately calibrate these changes have caused environmental movements and the damage they have caused in the system.
Thanks to him, it is possible to continuously monitor the buildings, to generate a database of your health, it would be like primer doctor.
Nervous system embedded
More specifically, the system has two parts. On the one hand, there is the aforementioned computational model, which includes all kinds of parameters and data on buildings, such as strength and density of its walls, beams, stairs on each floor, etc.
On the other hand, buildings are accelerometers would place that would detect vibrations and movements in them, from foundation to roofs or roofs. According to the authors of the advance, these sensors would represent “a nervous system embedded”.
For now, the MIT researchers have already tested the system in a building’s own research center, the so-called Green Building, which is a 21-story building made entirely of reinforced concrete and designed in the 1960s To do this, accelerometers 36 were used.
They have also developed a computer simulation of the building and introduced in it vibrations that could affect you.The model has allowed to predict how he would react the building and its various elements such vibrations. In principle it is safe, say the scientists, but is subject to some vibration, especially on the upper floors.
The team now plans now verify their computational model with laboratory experiments, particularly with a replica of 4 meters height of the structure of a building. The ultimate goal: to build buildings that can be equipped with sensors and algorithms central processing, which are intelligent, can ‘register’ your own health in real time and possibly resistant to extreme events.

Some carriers point to the risks of placing fiber to the home if there is any risk of having to lease their facilities to smaller ISPs. Many shibboleths are cited. My favourite is the prospect that radio-based services might become suddenly competitive with fiber.
Hmmn. Let me see. Take fiber’s carrying capacity. The information comes from wikipedia’s article on optical fiber. WDM refers to wave division multiplexing, the capacity to increase capacity by sending it over a different wavelength of light.
|Year||Organization||Effective speed||WDM channels||Per channel speed||Distance|
|Alcatel-Lucent||15 Tbit/s||155||100 Gbit/s||90 km|
|2010||NTT||69.1 Tbit/s||432||171 Gbit/s||240 km|
|2011||KIT||26 Tbit/s||1||26 Tbit/s||50 km|
|2011||NEC||101 Tbit/s||370||273 Gbit/s||165 km|
|2012||NEC, Corning||1.05 Petabit/s||12 core fiber||52.4 k|
While the physical limitations of electrical cable prevent speeds in excess of 10 Gigabits per second, the physical limitations of fiber optics have not yet been reached.
In 2013, New Scientist reported that a team at the University of Southampton had achieved a throughput of 73.7 Tbit per second, with the signal traveling at 99.7% the speed of light through a hollow-core photonic crystal fiber.
Thus, three years ago in 2011, Nippon Electric produced fiber that was composed of 370 channels capable of at 273 gigabits per second per channel, or 101 terabits per second.
Let us compare that to the carrying capacity of radio-based technologies, shall we?
An article on the IEEE 802.11 wireless radio standard shows that 802.11 ad standard, the fastest I could find) allows speeds of up to 6.75 gigabits/second. I am not an engineer, and there are, I am sure, dozens of qualifications to add to this observation, but, as a first approximation, standard radio technology permits a speed differential of five orders of magnitude between optical fiber and wireless. A gigabyte is one thousandth of a terabyte. 6 gigabytes/second for microwave radio versus 101 (102) times 1000 (103) gigabytes for optical fiber, makes a speed advantage of 105.
That is an advantage of 100,000 times.
Yes, I am aware of many issues of cost of installation not covered in this simple numerical comparison. My point is that, once you get fiber into the home, it is game over. There will never be a need for a competitive signal transmission pipe anywhere. Once transmission is re-monopolized, it will become clearer that competition must be in services, not pipes. Until that time there will be a lot of shouting at the bar.


Uniper is researching Bidirectional Charging Management for Electric Vehicles
- The project is aiming to efficiently interlink electric vehicles, charging infrastructure and the energy system
- Support of the interdisciplinary research project "BDL" of the Federal Ministry of Economics and Energy
- Efficient use of renewables in electromobility while increasing power supply reliability
Uniper has joined the “Bidirectional Charging Management – BDL (Bidirektionales Lademanagement)” research project, which was launched in early November. As part of the project, companies and institutions from the automotive, energy and scientific sectors will work together to develop technological solutions that make electromobility even more convenient, cost effective and low in emissions for users. The objective of the interdisciplinary project partners is to employ an unprecedented holistic approach in order to interlink vehicles, charging infrastructure and power grids in a way that facilitates the widest possible use of renewables, while also increasing power supply reliability. The research project will run for three years with the support of the German Aerospace Center (DLR) and with funding from the German Federal Ministry for Economic Affairs and Energy. Testing of the first 50 cars equipped with bidirectional charging technology (i.e. capable of feeding back power) is expected to start under everyday real-world conditions in early 2021.
Not only will electric vehicles with bidirectional charging capability be able to draw electrical power for their high-voltage battery when plugged into a compatible charging station or wallbox, they will also be able to reverse this process and feed energy back into the power grid. This will effectively turn the batteries of the electric vehicles into mobile energy storage devices that can also supply power when required, thus stabilizing the power supply system. Integrating as many electric vehicles as possible into the power grid in this way calls for innovations in terms of vehicle technology, charging hardware, charging management, communication interfaces with electricity providers and also with regards to the legal requirements. Bringing about these advances is the task of this research project, in which Uniper will be participating through the Research Center for Energy Economics (FfE). Within the framework of the research project BDL, the FfE will be focusing on questions relating to practical applications, the simulation of network loads in the distribution network and measurement concepts and data evaluation for the field test.
Uniper Project Manager Dr. Christian Folke: “Uniper is working on solutions at a variety of levels that make renewables more marketable and also increase power supply reliability. We are primarily looking at projects that deal with the effects and possibilities of digitalization and automation in an increasingly decentralized energy landscape. Our main focus here is on the flexibility of the energy system, which is often still lacking today. Technologies such as Power-to-X in the heat and electricity markets are extremely important for the breakthrough of renewable energies. The BDL project is essentially working on a storage solution and can provide us with new insights into how electromobility, which is mainly used in a decentralized manner, can be combined with an increase in grid and supply stability in the area. This could lead to highly flexible solutions that are able to dispute objections that still exist today regarding the risks that electromobility poses to the system as a whole, and in doing so, give renewables a boost”.
About the research project "Bidirectional charge management – BDL”
The innovation project "Bidirectional Charging Management - BDL" pursues the objective of developing and testing a holistic, user-oriented offer for the integration of electric vehicles into the energy system in Germany. Electric vehicles that can be regenerated can be used for network purposes by optimizing the absorption of energy from renewable sources into the public electricity network and at the same time keeping it stable. In addition to appropriate user-friendly technological solutions, this requires an intelligent interaction of vehicles, charging infrastructure and power grids. The interdisciplinary project partners from the automotive industry, the energy industry and science are developing holistic solutions for this.
In addition to the consortium leader BMW Group, the partners are KOSTAL Industrie Elektrik GmbH, TenneT, Bayernwerk Netz GmbH, Forschungsstelle für Energiewirtschaft e.V. (Research Centre for the Energy Industry) and the German Federal Ministry of Economics and Technology. (FfE), Forschungsgesellschaft für Energiewirtschaft mbH, Karlsruhe Institute of Technology (KIT) and the University of Passau. The innovation project is funded by the German Federal Ministry of Economics and Energy. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is responsible for the three-year pilot project.

Yb:CaGdAlO4(called CALGO) is a promising new laser gain material which possess several important advantages. The crystal structure of CALGO is tetragonal. When it is pumped at 979nm under pi configuration, we can get broad emission spectra from 994nm to 1050nm in theta configuration. This implies a very small quantum defect (down to 1.5%) and gives a good expectation of obtaining ultra-short pulse. Its thermal conductivity is also high: k=6.7W/m/K, which means it can be used for high power laser applications.
