Reliable and Horizontally Scalable NoSQL Data Store (via Toptal) (Development)
The client, a fast growing web startup in India, was faced with increasing schema complexity in their traditional SQL-based data tier, which hampered their ability to quickly onboard new developers. Their rapid growth and aggressive expansion into new markets was also straining the scalabilty limits of their current MySQL-based infrastructure.
Working with the company CTO, I researched, designed, and developed a prototype for a lightweight NoSQL data store which provides persistent data storage for all use cases specific to the client's products.
The data store architecture consists of a set of sharded MySQL database servers, divided into index shards and data shards. Application data is stored in the data shards as JSON strings, and Apache Avro is used to provide schema support for the JSON data.
The data store interface was implemented as a Swagger documented REST API exposing CRUD-like semantics. The service supports code generation in both Java and PHP, allowing clients to read and write application layer objects from the data store without having to manipulate or even know the underlying JSON representation.
The system was implemented in Java as a Spring Boot-based microservice.
High Performance Forensic Disk Imager (via Toptal) (Development)
I developed high performance parallel pipeline based disk imaging software for use in digital forensics applications. The software was developed in C++ and runs on Linux and Windows platforms.
High Performance Video Lottery Game Server (Development)
A J2EE-based video lottery game server developed for the Chinese market, constructed entirely on open source technology (JBoss 7) with an in-memory database (MySQL Cluster). It supports up to 20k gaming machines and 1.5k transactions per second.
The system has no single point of failure and is horizontally scalable. It employs advanced cryptographic techniques to ensure security and integrity and is fully internationalized, dynamically switchable between Chinese and English.
The server interfaces with an account management system using a secure REST interface and persistently maintains the game state in real time for each machine through cluster failovers, system restarts, and machine failures. It employs a plugin architecture for modules that allow for new games added as pre-packaged, digitally-signed Java. It passed Chinese government testing for security and integrity and includes a separate turnkey audit system to audit every transaction, verify, and digitally sign the software modules. It was implemented using a GWT front-end and a REST back-end based on Jetty and Apache Derby (JavaDB). The server was developed remotely, with only ten days on-site over the course of the eighteen-month project.
Windows POS Platform Back-end Server Integration (Development)
I developed a platform framework and associated Windows services in order to integrate a Windows 7 Embedded POS device that controls gaming machines located in geographically diverse venues (bars, hotels, etc) with a central network management service (NMS) and a content distribution service (DLS).
The project involved integrating an existing Java-based windows service that provides the basic gateway connector to the central services, and developing two new C# Windows services to allow application components on the POS platform to communicate with the central services through the Java gateway. The C# services communicate with the Java gateway using a proprietary TCP/JSON based protocol, and expose WCF Rest endpoints to talk to the POS applications.
The project was done primarily in C# with some Java, and used a SQL Server Express DB.
Slot Machine Interface Board (Development)
I migrated a proprietary legacy C++ gaming machine controller code base from a Red Hat Linux-based server platform to an off-the-shelf Freescale I.MX6-based system module (EDM-1). The application was a Slot Machine Interface Board (SMIB) that will be installed in video lottery terminals (VLTs) in order to convert the machine's native proprietary serial protocol to a TCP-based protocol that can be run over a LAN.
The project including building the appropriate embedded Linux kernel and file system image for the target hardware using the Yocto-embedded Linux development environment and adapting the application build procedures as appropriate. The migrated code base was turned back over the the client's engineering team for further adaptation to their proprietary I.MX6 SMIB.
The project was completed entirely remotely using components shipped from the client and my own lab systems and equipment.
The product is expected to be deployed to several hundred locations in South Australia sometime in late 2015.
Architecture for a National Account-based Lottery System (Development)
Architecture and design consultant for a project to build a national account based lottery gaming system for the China Sports Lottery. The system employs a service-oriented architecture and supports player account management, retail location management, and game service interface.
It is designed to allow seamless integration of diverse third-party game providers using a standardized plug-in interface.
The system is designed to scale to millions of player accounts, thousands of physical gaming locations and any number of game content providers. It supports land-based as well as online (Internet) gaming.
Once the architecture was complete, I performed the design and initial development of the retail location and gaming machine management module, then moved on to developing the first game server implementation to be used with the framework.
The architecture and development was conducted exclusively remotely from the US, with only a four-day brainstorming session in NYC to kickoff the project.
The system went live starting in Hainan Province in January 2015.
Mobile Gateway for Lottery Ticket Sales (Development)
I designed and developed a high-performance mobile gateway system for the Shanghai Welfare Lottery Corporation (SWLC).
The system enabled lottery ticket purchases acquired by diverse mobile application providers to be executed on the lottery's legacy back-end transaction processing system.
The system was implemented based on JBoss 7 and employed a JAX-RS REST API to communicate with the mobile application providers and a custom JCA resource adapter to communicate with the lottery's proprietary back-end transaction processor. It employed JPA/MySQL as the persistence solution.
The system serves as a gateway for potentially tens of millions of mobile users, and thus has very stringent requirements for both response time and transaction rate.
It was developed almost exclusively remotely from the US, with only five days on-site time in Shanghai to support the initial production roll-out.
The system went live in Shanghai in March 2013.
Enhancement and Ongoing Maintenance of a POS VLT Controller (Development)
I was responsible on an as-needed basis for the maintenance and enhancement of a JBoss 6-based "embedded" POS product.
The product functioned as a local controller ("site controller") for gaming machines (VLTs) in geographically diverse locations. It communicated with the gaming machines using a standard XML-based protocol (G2S) over TLS. It also communicated with a central State/Provincial management system using similar protocols. The original implementation was based on JBoss 6 with a PostgreSQL database.
The client had inherited the code base from a partner team that had failed to deliver a functional product. Over the course of numerous engagements, I re-factored and reworked the code base into a functional product, and added features and enhancements as requested, eventually migrating it to JBoss 7. The product is currently used for demonstration purposes and is considered highly successful in that role.
Mobile Electronic Instant Ticket Game Server (Development)
I designed and developed a high-performance electronic instant ticket (EIT) game server, used as a component in an SOA used for a mobile EIT sales system in Jinan Province, China.
EITs are the virtual equivalent of "scratch-off" lottery tickets. Instead of a paper ticket, the player uses a mobile application to obtain an encrypted ticket, which they then "scratch" using a mobile application. For any particular EIT game, there are pools with a fixed number of EITs and a predetermined number of winners at each prize level. These EIT pools are generated by proprietary algorithms and encrypted.
I developed the server, which allowed the EIT pool files to be securely loaded, verified, and distributed to the mobile users via REST interface. I developed the core code, UIs, and REST API.
I designed techniques using public key cryptography that ensured the EIT files could only be read by the gaming server that they were generated for, and developed the cryptographic techniques used to secure the "tickets" in transit and ensure that an EIT was only readable by the purchaser.
The system was implemented in Java on JBoss 7 using JSF for the UI and JPA/MySQL for the persistence layer.
Online Medical Survey System (Development)
I was the architect and principal developer for the creation of a J2EE-based internet medical survey system for a medical metrics firm.
The system is completely turnkey, and allows researchers to design complex custom medical surveys for targeted populations and then deploy them on the internet without any incremental web or back-end development.
The implementation was done on JBoss 5, using JSP, Hibernate, and MySQL.
Dial-up WAN TCP Proxy Service (Development)
I developed a serial line TCP proxy solution, implemented in C++, for TCP clients on geographically distributed systems to communicate with a central server over a secure dial-up connection. The solution is transparent to both client and server, who think they are communicating over ordinary TCP. My client had planned to use MS Remote Access Service (RAS) to allow local controllers to communicate with the central server, but RAS on Windows Server 2008 couldn't handle that number of connections at the time.
I built a system where a proxy application on the remote Linux client listens on a TCP port for incoming connection requests and forwards them to the proxy server, which receives the request over the serial connection and emulates the RAS service, forwarding it to the central server on a TCP port assigned to the client. The connection is accepted by the server and then at the remote side; data sent between the client and server is forwarded over the serial link.
The proxy service can handle multiple port-pairs and is used in production to proxy the RSync protocol. The serial link is secured using AES encryption and authenticated using a proprietary protocol certified as secure by South Australian gaming regulators.
Lottery Retailer Management System Integration (Development)
I developed a web service-based interface that allowed the Maryland Lottery to integrate the retailer management function between the lottery's UniSys back-end business systems and the POS system operator's proprietary Windows Server-based system.
Just for background, in the US, state lottery agencies usually sub-contract the deployment and operation of the online retailer point-of-sale network (POS) to specialist vendors. The lottery itself will manage the back-office business operations with their retailers (convenience stores, etc.). However, a subset of the information regarding the retailers must be shared with the POS vendor in order for the vendor to properly provide and service the retailers' lottery point of sale equipment.
The service I developed allows the lottery to push updates to the online vendor's system via a SOAP RPC-based web service. The service is fully automated and requires no operation intervention except to verify the reporting data. This replaces a manual process that required the retailer information to be redundantly entered into both systems.
The system was implemented in C# on IIS using ASP.NET technology. It has been in operation since October 2006.


Car Electrical & Repair in Austin, TX
The electrical system and wiring in a car carry electricity throughout the vehicle. Modern cars have miles of wiring, dozens of switches, modules, electrical motors and actuators.
Most all of the sensors, accessories and power equipment run by electricity. When a short or ground problem is encountered, a technician must manually trace the system using wiring schematics and special equipment. It is a time consuming task, even for the best technicians.
Many computer problems on cars can be traced back to bad connections and faulty grounds.
There is no preventative maintenance needed for the electrical system, but it is important to keep the battery and connections in good shape.
A battery and charging system test at each oil change can flag the car owner to potential problems.

Theoretical Investigation Of Relativistic Effects In Heavy Atoms And Polar Molecules
Nayak, Malaya Kumar
MetadataShow full item record
Extensive theoretical studies on the ground and excited state properties of systems containing heavy atoms have shown that accurate prediction of transition energies and related properties requires the incorporation of both relativistic and higher order correlation and relaxation effects as these effects are strongly inter- wined. The relativistic and dynamical electron correlation effects can be incor- porated in many-electron systems through a variety of many-body methods like configuration interaction (CI), coupled cluster method (CCM) etc. which are very powerful and effective tool for high precision description of electron correlation in many-electron systems. In this thesis, we investigate the relativistic and correlation effects in heavy atomic and molecular systems using these two highly correlated many-body methods. It is well recognized that, heavy polar diatomic molecules such as BaF, YbF, TlF, PbO, etc. are the leading experimental candidates for the search of violation of Parity (P ) and Time-reversal (T ) symmetry. The experimental detection of such P,T-odd effects in atoms and molecules has important consequences for the theory of fundamental interactions or for physics beyond the standard model (SM). For instance, a series of experiments on TlF have already been reported which provide the tightest limit available on the tensor coupling constant C , proton electric dipole moment (EDM) dp , etc. Experiments on YbF and BaF molecules are also of fundamental significance to the study of symmetry violation in nature, as these experiments have the potential to detect effects due to the electron EDMde. It is therefore imperative that high precession calculations are necessary to interpret these ongoing (and perhaps forthcoming) experimental outcome. For example, the knowledge of the effective electric field E(characterized by Wd) at the unpaired electron is required to link the experimentally determined P,T-odd frequency shift with the electron EDM de. We begin with a brief review of P,T-odd effects in heavy atoms and polar diatomics and the possible mechanisms which can give rise to such effects, in particular, the one arises due to the intrinsic electron EDM de. The P,T-odd interaction constant Wd is computed for the ground (2∑ ) state of YbF and BaF molecules using all-electron DF orbitals at the restricted active space (RAS) CI level. The RASCI space used for both systems in this calculation is sufficiently large to incorporate important core-core, core-valence, and valence-valence electron correlation effects. In addition to Wd, we also report the dipole moment (µe ) for these systems to assess the reliability of the method. The basis set dependency of Wd is also analyzed. The single reference coupled cluster (SRCC) method, developed by the cluster expansion of a single determinant reference function, is one of the most sophisticated method for treating dynamical correlation effects in a size-extensive manner. The non-uniqueness of the exponential nature of the wave operator diversifies the methods in multi-reference context. The multi-reference coupled cluster (MRCC) strategies fall within two broad classes: (a) State-Universal (SU), a Hilbert-space approach and (b) Valence-Universal (VU), a Fock-space approach. In this thesis, we shall be mainly concerned with the VU-MRCC which unlike SU-MRCC uses a single wave operator that not only correlates the reference functions, but also all the lower valence (or the so called subdued) sectors, obtained by deleting the occupancies systematically. The linear response theory (LRT) or equation of motion (EOM) method is another possible alternative which is nowadays extensively used to compute the atomic and molecular properties. Although, the CCLRT or EOM-CC method is not fully extensive in nature, this method has some distinct advantages over the traditional VU-MRCC theory. Further, for one-valence problem like ionization processes, the CCLRT/EOM-CC is formally equivalent to VU-MRCC, and hence, size-extensive. In this thesis, the core-extensive CCLRT and core-valence extensive (all electron) VU-MRCC methods are applied to compute the ground and excited state properties of various atomic and molecular systems (HCl, CuH, Ag, Sr, Yb and Hg) using nonrelativistic and relativistic (for heavy atoms) spinors. The similarities and differences in the structure of these two formalisms are also addressed. We also investigate the ground and excited state properties of HCN which is a system of astrophysical importance. This system has raised interest among the astrophysicists due to its detection in the atmosphere of Titan and Carbon stars. HCN has also been identified via radio-techniques in both comets and interstellar atmosphere. In the ash-photolysis of oxazole, iso-oxazole, and thiozole a transient band system was observed in the region 2500-3050 Å. This band system was attributed to a meta-stable form of HCN, i.e, either HNC or triplet HCN. We carry out detailed theoretical investigations using CCLRT and complete active space self-consistent field (CASSCF) method to characterize this unidentified band and other experimentally observed transitions.

In our internet-driven society, telecommunications networks are more critical than ever and will only become more integral. Despite their heavy influence on society, telecommunications systems don’t get many opportunities to shine in the spotlight. So today, we are celebrating telecommunications by exploring its basic principles and progress over the years.
In the 19th century, preliminary telephone networks utilized copper cables. These copper-based networks were the backbone of all telecommunications networks until the widespread adoption of Fiber Optic technology. Since copper cables are an analog technology, they transmit data using electrical signals through twisted pairs of insulated cables to reduce data loss and cut down on outside interference. For example, imagine a typical phone call on a vintage telephone like the one pictured above. First, a person on one end speaks into the phone; this voice data is then converted into electrical signals, which quickly travel along copper cables to the other end of the line, where the electrical signals are turned back into voice data for the person listening on the other end. This continues back and forth until the end of the call. Barebones copper cable networks, primarily used for telephones and telegrams until the first internet services became commercially available, is often called “Plain Old Telephone Service,” or P.O.T.S.
The first internet systems were eventually built on the back of the traditional copper telephone networks. These initial systems were not particularly fast, and the copper cables took up lots of physical space to transmit large amounts of data at an acceptable rate. Eventually, these systems were due for an upgrade. This is where Fiber Optics enters the picture, forever altering the basics of telecommunications networks.
Fiber Optics permanently changed the telecommunications industry as we know it by introducing cables that could transmit large amounts of data more quickly and effectively than traditional copper networks. While copper networks transmit signals using electricity, fiber networks transmit data through light signals. Fiber Optic cables have many small glass tubes inside them that allow light signals to pass through them incredibly quickly. These small glass tubes are called Fibers, and the light passing through them is called Optics, hence the name Fiber Optics. These fibers, made up of silica glass, are extraordinary because of their clarity, which helps transmit light signals effectively, and their toughness. Because of their composition, these glass fibers are resilient. They can handle being moved and bent, making them ideal for being used in aerial, buried, or underground applications. Light signals carrying user data are internally reflected within the fibers and their protective layers en route to their ultimate destination. These fibers are also much more efficient than copper cables. They can transmit more data faster and in a smaller-sized cable. For example, you could fit 144 fibers in a cable only ¼ of an inch thick! These tiny, mighty fibers transmit data, voice, and video signals at the speed of light to users worldwide!
What’s the next significant advancement in telecommunications networks, you ask? It’s hard to say! While Fiber Optic networks can still be improved to achieve even faster speeds and sustain larger bandwidths, there is no telling what kind of technological breakthrough in our future could lead to the next revolution in network construction. For now, at least, it is safe to say that Fiber networks rule the day, and only time will tell what kind of exciting progress we could see later.

NOTE: Information and images credited to Ken RadioThe term 3G refers to a range of wireless network technolgies, including WCDMA, CDMA2000, UMTS and EDGE. 3G combines high-speed mobile access with Internet Protocol (IP) based services. IP based services refers to most broadband Internet services including DSL, CABLE, and Wi-Fi. So what does change? By combining mobile access and IP services a device is no longer tied to static access points or bulky equipment. Users with 3G enable devices can connect from virtually anywhere using existing mobile or wireless broadband signals. See the image below for a comparison of devices from 1G to 3G (think of 3G as shorthand for ‘third generation’ ). How is this different or better than your existing cell phone?3G builds on the capabilities of existing devices. With 3G consumers will get faster service, more features, and improved connectivity. Here are some of the features 3G capable devices offer:Video: Download and save video footage for repeated viewings.Pictures: Capture and send pictures faster than existing cell phones allow.Games: More colors, more games, better control. More powerful devices means better mobile games.Location Services: GPS, mapping, and geo-tagging. 3G devices provide access to location based services. Use a 3G enabled device to recommend a service, restaurant, or movie theater based on your current location.Watch TV: Consumers with 3G enabled devices in Korea are already using them to watch their favorite television programs.By far the largest market for this technology is the US. When compared with other countries US consumers are more likely to consider features like mobile Internet, still camera, email, and mobile gaming when making their next purchase. 40% to 50% of US consumers who use mobile TV, electronic banking, on-line gaming, location services, and subscription services use them daily. This is a huge difference when compared to a global market average of 20% to 25% daily users worldwide.

Enhanced Endurance, Quieter Flight
New FOC sinusoidal driver ESCs and 8331 propellers mean that up to 4dB (60%) of aircraft noise has been lowered during takeoff and landing, and the Mavic Pro Platinum’s maximum flight time has been extended to 30 minutes, providing a quieter and more enjoyable flight experience. The 8331 propellers have a brand new aerodynamic design giving the Mavic Pro Platinum an impressive noise control performance, and new FOC ESC drivers offer sinusoidal current for increased stability.
OcuSync long-range-transmission technology is capable of relaying a signal up to 4.3 miles line-of-sight while supporting 720p HD video (1080p HD transmission in short-range mode). Every time you fly, OcuSync scans a range of available frequencies to find and use the one with the least interference to give you more reliability and control. Tightly integrated with the DJI GO app, OcuSync transfers vital statistics of the Mavic to you in real time, and can also be used to download photos and videos at up to 40 Mbps while flying.
12MP Raw/JPEG Still Photos
Every photo you take with the Mavic can be as big as 12 megapixels, with the ability to save in DNG raw or JPEG. You can even flip the camera 90-degrees for portrait oriented shots, just like you do with your phone.
UHD 4K and Full HD 1080P Videos
The Mavic Pro camera shoots 4K video (up to 4096 x 2160) at 30 frames per second and Full HD 1080p at 96 frames per second, so you can create incredible slow motion. Its minimum focusing distance is just 19", making it perfect for everything from the ultimate aerial selfies to landscape shots.
With ActiveTrack, just tell the Mavic who to track and it handles the rest. No GPS bracelets or transmitters are required. The Mavic has been trained to detect and recognize a number of common subjects including people, bike riders, vehicles, and even animals. Once you have marked your subject, you can fly around them to create a huge variety of shots, depending on the mode you are in. As the Mavic is tracking, you can even select exactly where you want the subject in the frame.
Three modes are available:
- Follow behind or in front of your subject, or circle it as it moves
- Fly alongside your subject
- Keep the camera trained on your subject while you fly almost anywhere
When you tap on your phone's screen, software translates your touch into a heading, including whether you want it to climb or descend. When you want to change direction, just tap somewhere else on your screen and the Mavic will smoothly turn to the new destination.
When you are flying over changing terrain, like following bikers riding uphill, the Mavic's Terrain Follow function uses height information gathered by the on-board ultrasonic system, and its downward-facing cameras to keep you flying at the same height above the ground even as the ground moves. Just set the height from the ground you want — from 9 to 33' — and focus on getting the right shot.
Sport Mode was designed for fun, giving the Mavic a top speed of 40 mph, all the while ramping up agility and responsiveness, to give you a taste of drone racing. You can also use it to film something fast, or zip out to catch a shot before the moment passes. Even in Sport Mode, the Mavic will stop immediately if you let go of the controls.
FlightAutonomy is the Mavic's brain and nervous system: a complex network of hardware and software that includes five cameras, GPS/GLONASS, a pair of ultrasonic range finders, redundant sensors, and a group of 24 CPUs to process and fuse all of this information
The Mavic is able to position itself accurately in a range of environments, beyond what is possible using basic "optical flow" technology, which depends on a single downward-facing camera and assumes that the ground below is always flat. Mavic is able to sense its environment in 3-dimensions and react to it, ensuring it hovers steadily, whether it is high up on the side of a cliff where downward sensors have no target, or under a forest canopy where satellite positioning is blocked and the ground is covered in uneven markings and obstacles.
As the Mavic flies, it scans the world around it, creating a 3D map that tells it exactly where it can fly and what it needs to avoid. Because it uses vision processing, it can see up to 98' in front and can accurately measure distance up to 49' in front, making it significantly more accurate than sonar based avoidance technologies. When the Mavic detects an obstacle and sees a way around it, it will simply adjust its route to fly around it. If it can't see a way around, it will slow to a stop gently and hover until you tell it what to do next.
In flight, the Mavic uses its compass to tell it where it is heading and the Inertial Measurement Unit (IMU) to tell it how it is flying. An interruption in the data flow from either of these may cause it to fly less reliably, which is why the Mavic has not one, but two of each. Whenever the system detects an inconsistency in one, it switches to the other, keeping your flight steady and reliable.
DJI Goggle Compatibility
The separately available DJI Goggle are FPV goggles designed to make flying totally immersive. The feature two 1080p LTPS displays with a wide 85° angle of view to give you a bird's eye view of the world around you. Built-in OcuSync connectivity means that it links directly to the Mavic and not through a cable or a Wi-Fi link to the controller. This seamless connection yields a delay of only 120 milliseconds.

The phone comes as a big relief for people living in far-flung areas where there is erratic or even no power supply.
Thursday, June 11, 2009: Now you can charge your mobile anywhere the Sun is shining when electricity is unavailable. Samsung has introduced its first solar-powered mobile phone, the Samsung Solar Guru (Guru E1107), in India. However, the solar power charging is only an option and not the main mode of charging. To charge the battery fully via the solar panel, the phone needs to be kept in the Sun for 40 hours.
The Samsung Solar Guru has the capacity to provide around five-10 minutes of talk time with one hour of solar charging. (Measured when the phone is turned-off under the sun light of 80,000 Lux. Results can be different depending on circumstances.) Moreover, the solar panel charging allows its users to save money and energy consumption on traditional electrical charging.
Last month, a Chinese manufacturer also announced a solar-powered cell phone. It claims that placing the phone under strong sunlight for one hour will support 15 minutes of talk time and about eight hours exposure to strong sunlight is required to fully charge the cell phone. Japanese electronics company Sharp is also planning to launch its solar-powered phone SH002, which can give one minute of talk time and two hours of standby with a 10-minute charge in the sun.
Solar Guru comes in a compact design with essential mobile phone features such as FM radio, MP3 ring tones, embedded games and a powerful torch light. For consumer safety, the phone offers mobile tracker, which automatically alerts when the SIM card is changed or sends out an SOS message in an emergency. Solar Guru also has a fake call feature, so users can pretend they have an incoming call to escape unsafe situations.
It measures 105.2 x 44.15 x 16.4mm, has a 1.52-inch screen with a resolution of 65K CSTN (128x128), supports dual GSM bands (900/1800MHz), comes with 1 MB of user memory and a 800mAh battery.
“Solar Guru represents our effort and commitment to strengthen our leadership in the solar panel mobile market,” said JK Shin, executive vice president, head, mobile communication division, Samsung Electronics.
Shin added, “With Samsung’s cutting-edge technology and consumer-oriented strategy, I believe Solar Guru will be the perfect fit for anyone in any market -- not only because it is solar powered, but because it has features that were designed to appeal to various cultures.”
Solar Guru also offers localised features for different countries. For instance, it offers profile screening for bikers in the Southeast Asian market that provides incoming call alerts only from selected contacts for safe riding. The phone also provides specialised features for different religions, such as alerts for prayer time.
Priced at Rs 2,799 (($59), the Samsung Solar Guru will be available in India, Europe, Southeast Asia, Southwest Asia, and Latin America from June 2009.
Initially, the phone is being imported from Korea. Samsung said Solar Guru would be manufactured in India from next month at the Noida factory.
You can also look forward to Blue Earth -- a pebble-shaped, solar-powered touchscreen phone from Samsung. Samsung presented the solar charging phone Blue Earth at Mobile World Congress 2009 in Barcelona earlier this year. The phone uses a small solar panel to provide power. A full solar charge of around 10 to 14 hours will provide enough power for around four hours of talk time.
Blue Earth is made from recycled plastic and features a special Eco Mode that users can access with a single click to wring the maximum energy use from the device.

What is LiteSim?
LiteSim is a service that offers Android emulators and a build server in the cloud for developers to connect to. The platform takes all the heavyweight development tasks and moves them from the local machine to a much more powerful remote server.
LiteSim eliminates the need for bulky hardware by offering Android emulators and build services running on a cloud server to facilitate faster creation of the next generation of Android apps. Right now, writing and testing a mobile app requires a powerful and expensive machine that can run all the required tasks for development. Depending on the speed of the hardware, the build process can take minutes and the emulators can perform unacceptably slowly. Additionally, the computer becomes very sluggish to use for other tasks while the emulator is running, adding up to a very bad user experience. Fortunately, all these pain points can be alleviated by moving the build and emulation tasks to the cloud, enabling software engineers to spend time doing what they’re best at.
- Run Gradle builds remotely for faster build times
- Remote Android emulators with hardware acceleration for maximum performance
- ADB and shell connections for ease of use
- Direct compatibility with Android Studio without the need for additional plugins
- Enable development from any machine regardless of hardware limitations

Ground Station Engineering
The telemetry, command, data handling and processing functions provide for the two-way flow of information between a spacecraft and its ground control station(s). At the ground station there are transmission (uplink) and reception (downlink) functions to perform, as well as the tasks of gathering and processing data.
The mission, orbit, type of payload(s) and the selected group of ground station(s) play an important part on determining the nature of the design of a satellite. A satellite is visible at all points on Earth's surface within a circle that is centered on the sub-satellite point, and whose diameter increases with satellite altitude. However, signals from satellites at the horizon limit are considerably attenuated by the atmosphere and so for practical purposes the surface coverage is restricted to the region in which the satellite elevation is above a given horizon degree.
VST is proud to provide services in a so noble discipline as astro dynamics. It is based on the laws of celestial mechanics applied to space vehicles, where some sub-domains are fundamental to deal with aspects of the mission related to the spacecraft orbit and attitude. Our professionals are directly involved on the mission preparation and operational activities supplying experts from different domains with relevant data about the orbit and attitude determinations.

A computer software was designed to facilitate identification of nematode species. The first section of the computer program was prepared to identify the species of the genus Criconemoides. NEMIDSOFT can be easily installed on personal computers with a minimal requirements. The software can be edited by users and developed and generalized to other genera of the nematodes. By having the morphological characteristics and morphometrical data entered in the search section of the software, some of already identified and closely related species in the database are introduced to the user as the most similar species to the understudied populations. The user, based on a description of the introduced species available in the database, is led to select one of the species that is closest to the population. NEMIDSOFT is a very user-friendly tool and is the first designed software for computer identification of nematodes in Iran.

Using antivirus technology, some type of computer is secured via malware, viruses, and spy ware. These dangers cost the global economy immeasureable dollars annually. Traditional anti virus software struggles to deal with these types of threats. Next-generation anti-virus technology uses advanced technologies to discover and prevent spyware.
Antivirus software uses artificial brains and behavioral analysis for and stop risks. These new tactics help the ant-virus solution appreciate fundamental human relationships and stop dangers faster.
Next-generation antivirus uses cloud-based technology to stop various kinds of cyberattacks. Cloud-based security solutions can be without difficulty implemented and are remarkably scalable. Additionally they reduce the information required for classic ant-virus software program.
Next-generation anti virus technology uses machine learning and man-made intelligence to analyze documents in the hinder. These new solutions also can identify and mass suspicious applications quickly. They will also decrease the risk of program defects.
Next-generation antivirus technology is built on artificial intelligence and behavioral analysis. This enables it to identify any type of trojans. It also uses machine learning how to learn from user experience.
Advanced antivirus solutions can also recognize scam https://globalwebreviews.org/avira-phantom-vpn-review/ exploits, adware, and spyware and adware.

These kinds of new tools are usually better by detecting fresh types of malware. They will also detect malicious applications that are in removable devices such as thumb drives. The solution also can sift through net activities and attachments to look for harmful spy ware.


Planet Earth is degrading at an alarming rate and countries are exploring to come up with solutions for sustainable living and attaining ecological balance on the planet.
At the same time, we envisage artificial intelligence (AI) and related innovations in smart, connected, and digital areas are set to drastically change societies & economies with extraordinary benefits including increased productivity, better efficiency, and improved public services.
However, one would be misled if one does not recognize the growing techno-anxiety because of the increasing influence of AI. There is this underlying fear that there will not be enough jobs due to technological advancements in AI & automation.
It is up to us to harness the power of cutting-edge AI technologies to ensure it rightfully augments human capabilities. Allowing us in making better decisions, focusing on what’s important, and accelerating sustainable technology development. We already see evidence of mission-driven AI benefiting key economic sectors and contributing towards sustainability.
In the field of environmental conservation, we see remote sensing based AI technology enabling wide scale monitoring for illegal fishing, and illegal logging for example which was hitherto not possible due to labor and capital constraints.
In the context of climate change, we see AI tools helping scientists develop Big Data based sophisticated climate models enabling us to understand different scenarios-based climate impact & hence drive coordinated actions, still when there is time.
Transitioning to a low carbon economy through increased adoption of renewable energy sources, driving energy use efficiency are all very critical. AI technologies are helping energy producers to decide when to switch to solar plants or wind turbines, as alternate source of power, depending on the time of the year & local weather changes.
One of the macro issues facing humans is food security in the face of increasing demand given the growing human population & average income level, degrading resources like arable land, and scarce water availability. Agriculture is responsible for ~25% of direct/indirect GHG emissions hence AI technologies have a huge potential impact in this area. We already see AI & related remote sensing, IoT, and cloud technologies improving food value chain efficiency for example through food waste reduction, increasing average yield levels, and enabling food traceability.
Though one can understand the techno-anxiety involved with AI technology adoption, but the role of government, education institutions, private organizations, and people in general needs to be underscored in re-skilling and transitioning the working population to adapt to a new digital economy and support wherever necessary the affected parties.
All these changes call for great leadership and coordinated world efforts. This can only be possible if we all come together united by challenges faced by the entire human race. I wish and hope for a united world harnessing the power of AI and innovating for the greater good.


Avalanche effectIn cryptography, the avalanche effect refers to a desirable property of cryptographic algorithms, typically block ciphers and cryptographic hash functions. The avalanche effect is evident if, when an input is changed slightly (for example, flipping a single bit) the output changes significantly (eg, half the output bits flip). In the case of quality block ciphers, such a small change in either the key or the plaintext should cause a drastic change in the ciphertext. The actual term was first used by Horst Feistel, although the concept dates back to at least Shannon's diffusion.
If a block cipher or cryptographic hash function does not exhibit the avalanche effect to a significant degree, then it has poor randomization, and thus a cryptanalyst can make predictions about the input, being given only the output. This may be sufficient to partially or completely break the algorithm. It is thus not a desirable condition from the point of view of the designer of the cryptographic algorithm or device.
Constructing a cipher or hash to exhibit a substantial avalanche effect is one of the primary design objectives. This is why most block ciphers are product ciphers. It is also why hash functions have large data blocks. Both these features allow small changes to propagate rapidly through iterations of the algorithm, such that every bit of the output should depend on every bit of the input before the algorithm terminates.
In the image : The SHA1 hash function exhibits good avalanche effect. When a single bit is changed the hash sum becomes totally differen
