We produce a range of standard shelters as well as custom-designed shelters to client’s requirements.


Arrays of cold atoms in optical tweezers are emerging as a promising candidate for developing quantum information processing architectures; striking results in the last few years range from the exploration of many-body dynamics to quantum optimization and computation. Yet, while coherent many-body dynamics can be controlled with high fidelity by driving the whole array with global lasers, on the other hand single-atom addressing remains a key technical challenge; so far, this latter type of control was believed to be necessary for universal quantum computation. On the contrary, in this work we develop a model for universal quantum computation which is entirely based on globally driving an array of cold atoms, without ever requiring single atom addressing – from initialization to readout. Our results open completely new perspectives for the design of atomic quantum processors, but also highlight novel and unexpected connections between quantum information and out-of-equilibrium many-body dynamics.

Dell has made a good living selling single-socket servers to small and medium businesses, and it is out there in front again supporting Intel's just-announced "Sandy Bridge-DT" Xeon E3-1200 processors in its PowerEdge machines.
There are eleven Xeon E3-1200 chips, with four of them being aimed at workstations specifically thanks to the integrated HD Graphics 3000 graphics processors on the die; the other seven can be used in single-socket servers or workstations with discrete PCI-Express graphics cards, which offer better eye candy than the integrated HD Graphics. No matter how the Xeon E3-1200 processors are used, they plug into the new Socket-H2 socket, which is also called the LGA 1155 socket and which is implemented on a platform Intel has code-named "Bromolow".
The Bromolow platform uses the "Cougar Point" chipset that Intel found a bug in back in January and that it has subsequently fixed to keep SATA drives from failing under certain circumstances. The Bromolow server platform offers three different Cougar Point chipsets, and there are eleven others for desktop and notebook PCs, all of which you can see here. The C202 and C204 chips are aimed at entry servers, including micro servers for hyperscale clusters that drive Web applications, while the C206 is aimed at Bromolow platforms that are for workstations using the integrated HD Graphics.
The Bromolow platform only supports a single processor socket and four DDR3 memory slots for that socket. If you want a single socket server that supports six memory slots, you'll have to wait for the "Sandy Bridge-EN" Xeon E5 processors in the third quarter, which will plug into Intel's Socket-B2 socket in one of four different "Romley" server platforms that will span the rest of the Sandy Bridge Xeon lineup.
Dell is kicking out two new Xeon E3 servers today, one in a tower configuration and another in a rack setup. And Dell thinks that SMBs are getting ready to do some upgrading under their desks and in their data closets.
The Dell PowerEdge T110 II entry server
"We still see some customers holding onto their three-year-old servers," Tony Parkinson, director of small and medium business at Dell, tells El Reg. "But I think the cost of running those older platforms is starting to hit home, and other customers are tired of trying to get by with a desktop as a server. They are seeing that there is some sign of economic recovery and they are trying to figure out if their infrastructure can handle growth and new client devices."
The PowerEdge T110 II is the tower server and it is the new entry point in a five-box Xeon tower server lineup peddled by Dell. The T310 is a single-socket Xeon box that has more peripheral expansion than the T110, and the T410, T610, and T710 are progressively beefier two-socket servers. Dell does not do tower servers based on Opteron processors from Advanced Micro Devices (and yes, that is odd).
The cutaway view of the PowerEdge T110 II server
Dell is opting for the C202 chipset in the T110 II server, and supports the full four slots of memory with memory stick capacities of 1GB, 2GB, 4GB, and 8GB at speeds up to 1.07GHz. The C202 chipset supports a mix of speeds on the PCI-Express 2,0 slots, and Dell's mobo has four slots (two x8s, one x4, and one x1). Dell is supporting the quad-core variants of the Xeon E3-1200 processors aimed at servers in the box (not the two-core, low-voltage E3-1220L, which is a 20-watt part aimed at real micro servers).
Most SMB shops using tower servers could care less if their chips burn 45, 80, or 95 watts and will go for the fastest four-core chip their budget will allow. The 3.3GHz E3-1240 would probably be the most popular one, looking at Intel's list prices for 1,000-unit trays of the chips. The 3.5GHz E3-1280 costs almost twice as much and is totally silly, and the extra money you pay for the 3.4GHz E3-1270 is not worth it, either.
If SMB shops want to splurge on anything, it should be on main memory or extra disk capacity – or even perhaps a server virtualization hypervisor. Although to say that is probably sacrilege to Intel.
They call it Cougar Point...
The T110 II server has room for four 3.5-inc SAS or SATA disk drives, and comes with software-based PERC S100 and S300 RAID disk controllers on the motherboard. (This is a Cougar Point chipset feature.) The server can also be equipped with a PERC H200 RAID controller, which is a real card not some software pretending to be one.
Dell is supporting 7.2K and 15K SAS drives and 5.4K and 7.2K SATA drives in the box. It comes with a two-port Intel Gigabit Ethernet NIC on the mobo, and additional Ethernet controllers from Intel and Broadcom are available for plugging into the PCI-Express slots. Dell has slapped a Matrox G200eW video card, a IMPI 2.0-compliant baseboard management controller that hooks into Dell's OpenManage server management tools, and a 305-watt power supply into the chassis.
The Dell T110 II is available starting today, but Dell's online configurator doesn't yet allow you to configure and price up a box as El Reg goes to press. Dell says an entry configuration will cost $635, but that is almost certainly not for a useful machine with proper capacity, an operating system, and support.
The second Dell server coming out today is the PowerEdge R210 II, which has similar feeds and speeds as the T110 II but some differences that rack server buyers want.
The machine has the same single Xeon E3-1200 processor socket and the same four memory slots with a maximum of 32GB of main memory. The same C202 chipset controls the box. But the R210 II has only a single PCI-Express x16 slot (instead of a variety of lower-speed peripheral slots) and only room for two 3.5-inch SATA or SAS disk drives; this server can also be configured with solid state drives if that makes your applications happy. The R210 II comes with a 250 watt power supply and the same Matrox video card and baseboard management controller that is used in the T110 II. A base configuration of the R210 II sells for $925; exactly what is in that configuration is not clear, and again, the online configuration and pricing tools have not yet been updated at Dell to let you go figure it out for yourself yet.
The Dell PowerEdge R210 II rack server
Generally speaking, the new T110 has 50 per cent more disk capacity than its predecessor (six drives compared to four) and twice the memory capacity (32GB instead of 16GB). The R210 has double the memory of its predecessor as well. Both machines have more energy-efficient power supplies as well.
Both the PowerEdge T110 II and R210 II servers support Windows Server 2008 R2, including the Foundation Edition and the new Small Business Server 2011 mashup of Windows, SQL Server, and other servers for SMBs. Parkinson says that he expects for SBS 2011 to be particularly popular on the new tower server.
Switching now to PowerConnect switches
As part of the SMB server rollout today, Dell is also updating its homegrown PowerConnect switches with two new families of devices, the 5500 series and 7000 series.
The PowerConnect 5524 is a fixed-port, top-of-rack Gigabit Ethernet switch with 24 ports and two 10 Gigabit Ethernet uplinks; the switches can be stacked eight high to allow them to be managed as a single logical device. It costs $1,297. The PowerConnect 5528 has 48 Gigabit Ethernet ports plus the two 10GE uplinks; it costs $1,851.
The PowerConnect 7000 series are Layer 3 data center switches. The 7024 model packs 24 ports into a 1U rack-mounted package and deliver 176 GB/sec of aggregate switching bandwidth. The 7024P has 24 ports as well but can support up to 30.8 watts of juice down the Ethernet wire to devices (such as IP telephones) per port. The base PowerConnect 7024 switch and the 7024P has four additional combo ports (which support SFP or standard Gigabit Ethernet ports), while the 7024F has four optional 10GE uplink ports. The 7048 switches doubled the fixed-port count up to 48 and boosts the switching bandwidth up to 224 Gb/sec.
The base 7048 has the four optional SFP or Gigabit Ethernet ports, the 7048P supplies power down the wire on all 48 ports, and the 7048R allows front-to-back or back-to-front cooling. (The R is for Rack.) There is no 7028F model with 10GE uplinks. You can stack up to a dozen of these 7024 or 7048 switches together to create a giant logical switch for network admins to babysit. The 7000 series switches range in price from $3,704 to $6,404, depending on features. ®


As artificial intelligence (AI) continues to advance, Nvidia is well-positioned to benefit from its growth. Nvidia is a multinational technology company that specializes in designing and manufacturing graphics processing units (GPUs) and system-on-a-chip units (SoCs) for the gaming, professional visualization, data centre, and automotive markets. They are widely known for their high-performance graphics cards that are used in gaming PCs and laptops. In particular, the company’s newest H100 data centre graphics processing unit (GPU) is already proving to be a game-changer for AI training and inferencing. So, what exactly is ChatGPT and why is Nvidia’s technology so important?
ChatGPT, or generative pre-trained transformer, is a type of AI language model that uses deep learning to generate natural language responses to prompts. It has been used for a variety of applications, including language translation, text completion, and even writing articles like this one. However, training and inferencing models like ChatGPT require enormous amounts of computing power, often requiring thousands of GPUs working in parallel.
This is where Nvidia comes in. With its latest H100 data centre GPU, the company has achieved a major breakthrough in AI computing. The H100 is nine times faster than its predecessor in AI training and up to 30 times faster in AI inferencing for transformer-based models like ChatGPT. This kind of performance boost is critical for AI applications that require massive amounts of computing power.
So, why is Nvidia’s technology so important for AI? First and foremost, the company’s GPUs are widely recognized as the best in the industry for deep learning and other AI applications. This has helped Nvidia establish itself as a leader in the AI hardware market, with a dominant market share in both data centres and gaming GPUs.
Additionally, Nvidia’s technology is designed specifically for the demands of AI. The company’s GPUs are optimized for parallel processing, which is essential for AI applications that require large amounts of data to be processed simultaneously. This allows Nvidia’s GPUs to perform tasks like AI training and inferencing much faster and more efficiently than traditional CPUs.
But it’s not just Nvidia’s technology that sets it apart. The company has also invested heavily in software development, creating a suite of tools and libraries specifically designed for AI developers. This includes the popular CUDA programming language, which allows developers to write code specifically for Nvidia’s GPUs. Nvidia also offers a variety of other tools and libraries, such as TensorRT and cuDNN, that are specifically designed for AI development.
So, what does all this mean for Nvidia’s future? Well, the company is already seeing significant growth in its data centre segment, thanks in large part to the demand for AI computing power. As we mentioned earlier, we forecast Nvidia’s data centre segment to grow at a 19% CAGR over the next five years, driven in part by the proliferation of AI.
But it’s not just data centre applications that are driving Nvidia’s growth. The company’s gaming GPUs are also in high demand, as more and more games are incorporating AI-powered features like real-time ray tracing and AI-enhanced graphics. This has helped Nvidia maintain its dominant market share in the gaming GPU market, despite challenges like the cryptocurrency mining crash and elevated channel inventories.
Nvidia is well-positioned to benefit from the growth of AI, thanks to its industry-leading GPUs and software tools. With its latest H100 data centre GPU, the company has achieved a major breakthrough in AI computing that is already proving to be a game-changer for AI training and inferencing. As AI continues to advance and become more widely adopted, we believe Nvidia will likely continue to be a major player in the industry.

Paul Werbos is best known (and most cited) for the original discovery of backpropagation, and for the theorem establishing its validity, as part of his PhD thesis in Applied Mathematics for Harvard in 1974. Even before 1974, he had developed backpropagation as one element of a more general approach to reinforcement learning, which combined a new way to learn to approximate dynamic programming with key insights from Freud’s theory of how learning works in neurons of the brain. He inaugurated the field which we now know of as RLADP, Reinforcement Learning and Approximate Dynamic Programming, building on this earlier work, his later papers, and on the research area of Adaptive and Intelligent Systems at NSF which he led from 1988 to 2015. This included neural networks, adaptive fuzzy logic, and a major paradigm shift in how to understand intelligence in the brain, which has passed tests on the best real-time brain data (Werbos and Davis 2016).
Backpropagation and RLADP are the main foundations of the new deep learning revolution, which can be traced back to a research program he started at NSF, Cognitive Optimization and Prediction (COPN), and to an award he pushed there to Andrew Ng and Yann LeCun, whose success stories they conveyed to Sergey Brin at Google. AIS also led to more powerful and advanced developments and applications of RLADP, where massive new breakthroughs are still appearing, in areas from electric power, to the control of air and ground vehicles, and in new options for quantum technology for observing the sky, quantum RLADP and cybersecurity. These are reviewed in his new paper, Quantum Technology to Expand Soft Computing, in Systems and Soft Computing (Elsevier), December 2022.
Paul Werbos has probed deeper into how climate change actually does pose a threat to human species existence, and how new IEEE technology and market design could be combined to solve these problems at a much lower cost than any of the well-known existing approaches. These efforts have only just begun, but they have demonstrated already how IEEE technologies (which include market design as in electric power) would allow vastly more impact than present climate policies, at lower cost, and faster. (build-a-world.org).
He has also been active for decades in IEEEUSA, in the planning committee of the Millennium Project, and in the National Space Society. In 2009, as a legislative fellow handling climate and many other areas of science for Senator Specter, he learned the realities of many S&T challenges facing the world today.

The ground bond test (also called PE resistance test, ground continuity test), is the first test required by the electrical safety testing standards. The ground bond test consists in testing whether the ground points of a device under test are well connected in between each other, and also to the mains ground.
Beside above, what is earth continuity? EARTH CONTINUITY TEST. This test is carried out on all Class I appliances during PAT Testing. The purpose of the test is to check that there is a good connection between the Earth pin on the plug and the case of the appliance. A good connection is defined as having a resistance of less than 0.1 ohms (or 100 milli-ohms)
Beside this, how do you check for ground continuity?
Hold one lead on the ground terminal (a chassis bolt will do fine) and the other lead on the terminal/s you wish to test. If your meter beeps, it means you have continuity. If it is on ohms scale, you will have continuity when it reads close to 0 ohms.
What is the continuity symbol on a multimeter?
Continuity: Usually denoted by a wave or diode symbol. This simply tests whether or not a circuit is complete by sending a very small amount of current through the circuit and seeing if it makes it out the other end. If not, then there’s something along the circuit that’s causing a problem—find it!
Why continuity test is needed?
A continuity test is an important test in determining the damaged components or broken conductors in a circuit. It can also help in determining if the soldering is good, if the resistance is too high for flow of current or if the electrical wire is broken between two points.
What is a good earth continuity reading?
Earth Continuity Test The maximum acceptable value is generally 0.5 ohms although certain standards may specify 0.1 ohms.
Is resistance the same as continuity?
Generally speaking, continuity indicates whether or not current will flow in a circuit. Resistance indicates how much current will flow.
How do you test for earth bonding?
The earth bond test measures the resistance of the earth from the pin of the mains supply plug to the earthed body of the appliance and indicates how good the connection is. The earth bond test probe is connected to the appliance earthed reference point and acts as a return.
What is the minimum acceptable value of insulation resistance?
Insulation resistance should be approximately one megohm for each 1,000 volts of operating voltage, with a minimum value of one megohm. For example, a motor rated at 2,400 volts should have a minimum insulation resistance of 2.4 megohms.
What is the acceptable earth resistance value?
Unfortunately, there is not one standard ground resistance threshold recognized by all certifying agencies. The NFPA and IEEE recommend a ground resistance value of 5 ohms or less while the NEC has stated to “Make sure that system impedance to ground is less than 5 ohms specified in NEC 50.56.
How do you use a continuity tester?
To use a continuity tester, unplug the appliance and disassemble it to get at the component you want to test. Fasten the clip of the tester to one wire or connection of the component, and touch the probe to the other wire or connection.
How do you check for a short to ground with a multimeter?
Set the multimeter to measure resistance (ohms). Place one lead on the chassis or the negative terminal of the battery, and the other lead to the ground wire. If the resistance shows continuity (zero resistance) then the wire is okay.
Can you check continuity on a live circuit?
Now, we’ll tackle the second-most common use of a multimeter in a car—measuring resistance and verifying continuity. You can measure the voltage and the current of a live circuit and use those figures to calculate the resistance (Ohm’s Law), but you can’t actually measure the resistance of a live circuit.
What is a polarity test?
Electrical polarity (positive and negative) is the direction of current flow in an electrical circuit. In the context of electricity installations, a polarity test is used to confirm the correct connection of the line and neutral conductors.
What does OL mean on a multimeter?
What is an Open in a circuit?
a) Open circuit means the wires are cut off so there will be no current flow, but there is voltage. b) Closed circuit means the wires are connected so there will be flow of current, but there is no voltage. c) Short circuit also refers closed circuit.

In May 2013, PMB acquired all the shares in the MGG Micro-Incandescent Menzel GmbH. MGG is a well-known producer of micro-lightbulbs, which are mainly used in the field of safety and medical technology as well as aerospace. MGG was founded in 1963. The first miniature incandescent lightbulbs produced at the time were still produced manually by experienced glassblowers. As demand grew, production became increasingly automated. The incandescent lightbulbs produced by MGG are frequently used as components of sensors, for example for the detection of gases or for the authenticity testing of banknotes. The acquisition of MGG shows that PMB also offers an ideal home for small and medium-sized companies. This is especially true if there is no suitable successor in the company, as was the case with MGG.

- 2,000 hours of remote client logins
- 4,000 hours of direct cluster testing
- 60,000 hours of software-simulated cluster testing
- 12 major computer chess tournament wins in 12 attempts, including 2 ACCA World Championships and 3 ICGA World Championships


we go deep in the phenomena related to the blue sky nature, we have
to study the interaction between light and particles of small
size, the so-called Rayleigh Dispersion.
when any electromagnetic wave (such as sunlight) finds in its trajectory
an atom (or a small molecule), it interacts with its cloud of electrons,
transmitting energy to the atom. This causes that the atom lowest
level of energy (the natural state) begins to vibrate.
oscillating electrons do not keep on vibrating for a long time.
They return to the initial state by irradiating some of the energy
they have got. Lord Rayleigh studied the dependence between the
amount of irradiated light and the light wave length. He set up
that the quantity of irradiated light is inversely proportional
to the fourth power of the wave length. It can be represented as:
if the incident light is white (an addition of different wave lengths
or colours), the irradiated light will contain a higher amount of
colours with shorter wave length (blue and violet) and less amount
of colours with longer wave length (yellow and red). So we came out
to the same conclusion than in the previous section.

In an effort to save electricity and money, quite a lot of hotel around the world have a little contraption inside the room close to the door, into which one inserts one's room key card to turn on the electricity in the room.
I, being the lazy type, like to keep my key card in my pocket. I being the crazy inventor and tinker type, also keep coming up with ways to make that possible.
So I inserted a Translink transfer (bus ticket) into the slot together with the key card and then withdrew the key card. Lo and behold: It works.
This morning, Hans complains that the TV doesn't work anymore. I blame it on empty batteries in the remote control
Then I close a desk drawer while the charging cable of my laptop extends into the drawer. A minute later, I realize that my charger no longer works ! OH NO. Where in Mexico will I find a new SONY laptop charger? I try the charger in all 2 available outlets in the room and it seems to be kaputt ;-(
Felipe, the most friendly of the Lobby Boys, directs me toward a mall only 5 minutes walking distance away. And indeed I find an original re-built SONY charger for 450 Pesos (~CDN 38). But I also have to buy an adapter to go from a 3-prong plug to a 2-prong plug, which is all that is available in the room.
I return to the room. The 3-to-2-prong adapter is welded into plastic. I can't open it without scissors. I'm stuck I have an idea. Since the room lights are working, it can't really be my ingenious invention with the card-switch-device that is at fault for no power out the outlets, or could it be my ingenious invention after ?
I decide to test it with the blow dryer in the bathroom. Even though the lights are on, the blow dryer (using an outlet) is not working. OH NO !!! I remove the paper bus ticket and insert my key card. The blow dryer works again. OH NO !!!! And so does the laptop charger !!!
I feel simultaneously STUPID for having missed this and INGENIOUS for having fixed the TV, the blow-drier, and my laptop charger problem in one step. And I have a spare laptop charger now.
Who could have thought that the key card switch is a two-stage switch that allows the room lights to remain on but kills the power to the electrical outlets??


Under the Fifth Sun
In electronics, a vacuum tube, electron tube (in North America), tube, or thermionic valve or valve (in British English) is a device controlling electric current through a vacuum in a sealed container. The container is often thin transparent glass in a roughly cylindrical shape. The simplest vacuum tube, the diode, is similar to an incandescent light bulb with an added electrode inside. When the bulb’s filament is heated red-hot, electrons are “boiled” off its surface and into the vacuum inside the bulb. If the electrode—called a “plate” or "anode"—is made more positive than the hot filament, a direct current flows through the vacuum to the electrode (a demonstration of the Edison effect). As the current only flows in one direction, it makes it possible to convert an alternating current applied to the filament to direct current.
The introduction of a third electrode, a grid between the filament and the plate, yields another function. A voltage applied to the grid controls the current flowing from the filament to the plate. Thus, it allows the device to be used as an electronic amplifier.
Vacuum tubes are thus used for rectification, amplification, switching, or similar processing or creation of electrical signals, and could be used for all applications that semiconductors (and thus computer ships) could be used for, just at a very large (and much less efficient) scale.

Common AC Problems That Require Repairs
Air conditioning units have a limited service lifespan due to the eventual occurrence of failure of AC system components. When this happens, you need an HVAC repair service Cabot, AR residents can rely on to make the needed repairs in a timely fashion. At Steadfast Heat & Air, we offer an array of AC repair near Cabot, AR that restores your air conditioning system to proper and efficient functioning.
Some common AC problems might require you to contact our professional HVAC team include:
Primary Motor Starter
A motor operates similarly to a car engine. Your AC unit has a primary motor starter can sustain damage or fail which can prevent your system from switching on from the thermostat.
In a car air conditioning unit, a thermostat causes the activation of a switch that results in electricity being sent to the unit. The switch activated causes the pulling of points which open and close which can result in pitting and burning. If the primary motor starter appears burned, pitted, or otherwise damaged, it is better to replace the unit.
Refrigerant functions within an air conditioning system as a cooling fluid. If your vehicle’s AC unit is expelling warm air, the refrigerant level may be low. This may result in a chain reaction within the air conditioning unit that may cause the coil and other parts to freeze up and cause AC system failure. An old AC unit may also have loose fittings that cause leakage. An experienced AC repair service professional can check for leakage, refill the coolant, and repair leaks.
Secondary Motor Controller
The secondary motor controller in an air conditioner controls the supply of voltage from the electrical source. A controller that is not operating properly can cause the wrong voltage to be sent to the system, negatively affecting the entire system.
Replacing a faulty compressor in your AC can be quite expensive. This is why proper compressor maintenance and repair as needed is important. A compressor pumps coolant through a coil from outside the unit and then distributes cold air throughout the AC system. If debris has collected or airflow is inadequate for some reason, or if the installation was poor, the compressor may fail.


Android Remote Control
Troubleshooting an Android device from afar demands a reliable, remote solution. Enter TeamViewer Remote Control: an app that simplifies connecting remotely from one device to another. Here, we'll take a closer look at TeamViewer Remote Control, how it works, and how you can use the app to troubleshoot Android devices remotely.
Android Remote Control
TeamViewer is a lightweight remote control or remote monitoring application used for web conferencing, transferring files, and troubleshooting. It supports many platforms, including iOS, Windows, ChromeOS, Mac, Linux, and, fortunately for us, Android.
TeamViewer has expanded its features over the years, evolving into a suite of apps including TeamViewer Tensor and TeamViewer AR. But TeamViewer Remote Control remains its most popular app, and it's what we'll be using throughout this guide. Let's look at a few examples of problems you can solve remotely using it.
Using TeamViewer Remote Control, you can successfully troubleshoot many software-level issues by remotely connecting to another device. You can solve problems by taking preventative steps to keep malware off an Android device or remove pesky apps that keep draining a device's battery, for example.
Instruct the person that needs remote assistance to open Google Play and search for TeamViewer Host (or send them the link for TeamViewer Host on Google Play). You should then follow the steps we used earlier to check if their device is supported. If they can see TeamViewer Host, ask them to tap Install.
Tap the name of the device, then Remote Control. The host device will display a window saying that TeamViewer Host will start capturing everything displayed on the screen. They must tap Start Now before the connection attempt is successful. Once connected, you will have complete remote control over the host device.
Connecting remotely to a device used to be an exercise in futility. But those days are over. Thanks to TeamViewer Remote Control, it's easy to remotely connect to an Android device and lend your Android knowledge to your friends and family, wherever they are.
Android remote control allows IT admins to remotely access Android devices. Implementing remote control apps expedites the troubleshooting process, thereby decreasing device downtime. Administrators can detect and fix issues from the comfort of their home or desk at work as they can remotely operate Android devices from PCs. Beyond sheer convenience, remote access significantly reduces IT support and maintenance costs.

What can you do if the laptop LCD screen turned completely white? From my experience I can tell that this problem may be related to the following:
1. Loose connection between the video cable and the LCD screen.
2. Defective LCD screen.
3. Defective motherboard (I assume the graphics card is integrated into the motherboard).
Here's an example of a laptop with white screen. When you turn on the laptop, it starts but the image on the screen is completely white right from the beginning. In my case it was a Toshiba Satellite M45 laptop but this problem may occur with any other brand.
Most likely you still can use the laptop with an external monitor. Just connect the monitor to the VGA port on the back or side of your laptop and then switch the video output from internal to external mode.
On Toshiba laptops you can toggle between internal and external screens using Fn+F5 keys. Hold down Fn and press on F5 until you get video on the external monitor.
On IBM laptops use Fn+F7.
On HP laptops use Fn+F4.
It's possible that you have to use a different key combination on your laptop but you get the idea.
On some laptops, in order to be able to use the external monitor, you have to connect it to the laptop and then restart the laptop so the external monitor is detected by the laptop.
I noticed that in some cases the laptop screen may turn white because of poor connection between the video cable and the LCD screen. If you want to check this connection, you'll have to take apart the display panel because the connector is located on the back side of the LCD screen.
These laptop service manuals and disassembly instructions may be useful.
I always check the video cable connection first. Reconnecting the video cable may fix your problem.
If reconnecting the video cable doesn't help, most likely you have a problem either with the LCD screen or with the motherboard.
The best way to find out witch one is causing the problem is testing the laptop with another working LCD screen. Without this test you'll have to guess because as I mentioned before this could either bad motherboard or bad LCD screen.
You'll have to disconnect the video cable from the LCD screen (connector 2) and the inverter board (connectors 3 and 1). After that you connect another working screen and test video.
For this purpose I'm using one of my test LCD screens. My test screen is cracked and because of that you see a wide white band in the center but it still works fine for this test.
The original screen is white but my test screen works normal (except the crack of course) and I can see the image. After this test I can tell that the problem must be related to the screen.
After I assembled everything back together and connected the original LCD, it's still white.
In this guide I will disassemble a laptop LCD screen in order to remove and replace the backlight lamp (CCFL). Replacing the backlight lamp is not an easy task even for experienced technicians. If you do something wrong you will permanently damage the LCD screen and have to buy a new one. Proceed on your own risk and do not blame me. Some recommendations before you start:
1. Work in a clean room. You don't want dust and lint inside your LCD screen.
2. Make notes, so you know how to assemble your screen back.
3. Take pictures.
4. Before you remove something, take a closer look at the part and memorize how it is assembled.
5. When you are assembling the screen, remove dust and lint with compressed air. Do not use cloth.
The backlight lamp (CCFL) is located inside the LCD screen, so we are going to take it apart. In this article I'm not going to explain how to remove LCD from a laptop, it's been covered before.
Remove sticky tape and foil from the back of the screen and glue it somewhere so you can reuse it later, when you assemble the screen.
Removing tape from the backlight cables.
On my screen the green circuit board was glued to the plastic frame with a double sided tape. Carefully unglue the circuit board. Be very careful, do not flex or bend the circuit board.

In November, a Chinese space mining startup, Origin Space, will launch the world’s first space mining robot into Earth orbit (designated NEO-1). Once in orbit, NEO-1 will perform a series of tests to ensure it works properly. This proof-of-concept is the first of its kind and, if successful, will pave the way for China’s budding space mining industry to take flight.
It is believed that the world’s first trillionaire will come from the space mining industry. Following the launch of NEO-1, Origin Space plans to place a small observation satellite, Yuanwang-1 (or “Little Hubble”), in Earth orbit next year to search for mineable asteroids. Beijing has identified space mining as new strategic industry that China must dominate in order to fulfill President Xi Jinping’s goal of making the People’s Republic of China the world’s hegemon by 2049.

Humans may get Elon Musk’s brain chips that stream music implanted soon
Last July, we learned that Elon Musk and his company Neuralink want to ditch headphones for good with a brain chip that can stream music among other things.
Now, it looks like Musk hopes to start implanting these computer chips into actual human brains very soon.
Along with influencing Reddit‘s GameStop stocks ploy and becoming the world’s richest person, Musk has been hard at work developing those brain chips. Back in July, we learned that Neuralink is developing a computer chip that can influence a multitude of things when implanted into someone’s brain.
Ultimately, the company aims to provide long-term treatment for neurological conditions such as dementia, Alzheimer’s and spinal cord injuries with these chips. As well, the chips also have the potential to stream music directly into the brain.
Last summer, Neuralink reportedly had successful tests of the technology on mice and apes. Human subject testing was meant to begin in 2020. However, the coronavirus pandemic delayed those plans.
Then, on Jan. 31, Musk reportedly told users of the private app Clubhouse that Neuralink successfully implanted a wireless chip into a monkey’s brain. According to Musk, the animal was able to play video games using only its mind.
“You can’t even see where the neural implant was put in, except that he’s got a slight like dark mohawk,” Musk said.
Now, it looks like Neuralink plans to begin testing on human brains sometime this year. On Feb. 1, Musk responded to a Twitter user who asked to participate in the human trials.
“Hi @elonmusk, I’ve been thinking for a long time how to write this to you – but I’ll keep it very simply: I was in a car accident 20 years ago and have been paralyzed from the shoulders ever since. I’m always available for clinical studies at @Neuralink. Please get in touch!”
Musk confirmed that Neuralink is closely working with the FDA to get approval on the testing. They want to make sure implanting the brain chips are safe for humans before moving forward.
“Neuralink is working super hard to ensure implant safety & is in close communication with the FDA. If things go well, we might be able to do initial human trials later this year.”
Neuralink is working super hard to ensure implant safety & is in close communication with the FDA. If things go well, we might be able to do initial human trials later this year.
— Elon Musk (@elonmusk) February 1, 2021
Besides tweeting about pronouns and questioning the accuracy of rapid COVID-19 tests, Musk has been using Twitter to recruit Neuralink employees. On Jan. 31, he sent out two tweets encouraging individuals who are interested in what Neuralink is working on to apply for a position.
If you’ve worked on advanced wearables, phones or robots, those skills are needed @neuralink

"The 'Sphere': A Dedicated Bifurcation Aneurysm Flow-Diverter Device" was the most downloaded article published in CVET in 2015-16, demonstrating the widespread interest in the pioneering technology developed by MINT. The paper presents results from Computational Fluid Dynamics (CFD) modelling of ‘Sphere’, which is a prototype flow-diverter device intended to treat bifurcation aneurysms of the cerebral vasculature.
In both steady state and transient flow simulations the device presents a range of aneurysm inflow reductions, with mean flow reductions falling in the range of 30.6–71.8% across the different geometries. Based on the extensive analysis undertaken in the paper it is concluded that the ‘Sphere’ device offers very significant levels of flow reduction in a number of anatomically accurate aneurysm sizes and locations, with many advantages compared to current clinical cylindrical flow-diverter designs.
CVET is a highly respected journal in the cardiovascular field and presents a wide spectrum of research, from basic to translational, in all aspects of cardiovascular physiology and medical treatment.
Dr. Tom Peach, the lead author on the paper, recently accepted the award at the 2016 Biomedical Engineering Society (BMES) Conference held in Minneapolis, MN from 5-8 October.

In recent years, office building owners have been looking for ways to reduce energy expenditures while still providing a comfortable and productive work environment. One of the most effective methods for achieving this goal is to implement efficiency improvements in the building. These improvements can range from simple changes like installing energy-efficient lighting and appliances to more complex upgrades such as installing solar panels or geothermal systems. By making these changes, office building owners can reduce their energy bills and help the environment at the same time.
One of the most common efficiency improvements that office building owners are making is installing energy-efficient lighting. By replacing traditional light bulbs with LED bulbs, owners can reduce their energy costs by up to 80%. LED bulbs also last longer than traditional bulbs, which means they need to be replaced less often. Additionally, LED bulbs produce less heat, which can help keep the building cooler and reduce air conditioning costs.
Another way that office building owners are reducing energy costs is by installing energy-efficient appliances. Many appliances, such as refrigerators, dishwashers, and washing machines, use a lot of energy. By replacing these appliances with Energy Star-rated models, owners can reduce their energy bills significantly. Additionally, many of these appliances come with additional features such as timers and temperature controls that can help further reduce energy consumption.
Finally, office building owners are also taking advantage of renewable energy sources such as solar panels and geothermal systems. Solar panels capture the sun’s energy and convert it into electricity, which can be used to power the building. Geothermal systems use the earth’s natural heat to provide heating and cooling for the building. Both of these systems can significantly reduce energy costs and help protect the environment.
By implementing these efficiency improvements, office building owners can reduce their energy expenditures while still providing a comfortable and productive work environment. These changes can help reduce energy bills and help protect the environment at the same time.
