Learn about the basics of Machine Learning and how to use Python libraries like scikit-learn to build machine learning models
Machine learning is a rapidly growing field that allows computers to learn and make predictions without being explicitly programmed. It is a powerful tool for a wide range of applications, from image recognition and natural language processing to fraud detection and predictive analytics. Python is one of the most popular programming languages for machine learning, and has a rich ecosystem of libraries and tools that make it easy to build and deploy machine learning models.
In this article, we will provide an introduction to machine learning with Python and cover the basics of different machine learning algorithms and how to use Python libraries like scikit-learn to build machine learning models.
First, let’s take a look at the basic building blocks of machine learning. The three main components of machine learning are the model, the data, and the learning algorithm.
The model is the algorithm that you will use to make predictions. In scikit-learn, you can choose from a variety of pre-built models, such as linear regression, decision trees, and support vector machines.
The data is the input that you will use to train the model. In scikit-learn, you can load data from a variety of sources, including CSV files, SQL databases, and NumPy arrays.
The learning algorithm is the method that the model uses to learn from the data. The most common learning algorithms are supervised and unsupervised learning. Supervised learning is used when the output is known, and unsupervised learning is used when the output is unknown. Scikit-learn supports both supervised and unsupervised learning.
Now that we have a basic understanding of the components of machine learning, let’s build a simple machine learning model using scikit-learn. For this example, we will use the Iris dataset, which is a dataset of flower measurements that is commonly used for machine learning.
Here’s an example of how to load the Iris dataset and train a simple model using scikit-learn:
from sklearn.datasets import load_iris

The insurance industry is one of the most important industries guarding the well-being of the people you serve. However, in this current environment, there are many challenges to overcome for yourself and your clients.
- Remaining cost-effective in shifting economies
- Maintaining and edge against rising competition
- Responding to changes in customer requirements
- Preserving assets during unforeseen natural disasters
- Staying secure amidst everchanging cybersecurity threats
These are just a few of the challenges facing Property & Casualty insurance providers looking to stay increasingly agile, responsive and strong.
To better navigate current potentialities, emerging technologies like artificial intelligence (AI) and machine learning (ML) are helping insurance carriers provide better services for their customers while setting up their businesses for future success. Here is how AI and ML work in Property & Casualty Insurance.
How Do AI and ML Work?
AI uses intelligent machines to simulate human thinking in order to solve problems that are too big for the human mind to grasp. ML takes the data insights uncovered by AI and leverages them to learn without direct programming. These combined improvement capabilities help P&C insurance companies to become more competitive, productive and accurate.
Both AI and ML can be categorized under the umbrella of Intelligent Process Automation (IPA), which describes the use of advanced technologies to manage, automate, and integrate digital processes in daily workflows. Carriers use AI and ML to address complexity issues within different areas of operations, such as policy writing. Advanced intelligence enhances security by detecting when applicant information may be fraudulent.
Other advanced technologies include:
Digital Process Automation
Digital Process Automation (DPA) is a digital technology that can automate one or more tasks in a business process. Many Property & Casualty Insurance Providers use DPA as a way to invoice and process payments. With DPA, processes are partially automated, so it still requires some form of human interaction. Benefits to DPA include:
- Reduced Operational Costs
- Better Customer Service
- Increased Employee Satisfaction
- Better Compliance and Security
The core function of AI and ML is to replicate human cognition and perform tasks the way a human would with more accuracy and efficiency. Because humans are independent, action-oriented beings, AI and ML capabilities are autonomous and self-improving. AI can handle both complex and repetitive tasks. Some of the benefits to AI include:
- Minimize Errors
- Increase Business Efficacy and Efficiency
- Provides Smart Decision Making
- Can Solve Complex Problems
- Can Handle Repetitive/ Mundane Tasks
- Provides In-Depth Research and Analytics
Robotic Process Automation
Robotic Process Automation (RPA) is the technology that builds, manages, and deploys software robots. These robots mimic human interactions with digital systems, software, and customers. These robots can understand processes like navigating systems, understanding what’s on a screen, completing keystrokes, extracting data, and more. These robots can complete a wide range of functions and services. Benefits to RPA include:
- Adaptable to Workflow Changes
- Highly Accurate
- Increased Productivity
- Better Employee Engagement
How Insurance Carriers Use AI
AI is a powerful tool that can impact the insurance industry in many ways. Insurance companies use AI to assist with data migration, claims processing, underwriting, fraud detection, and customer service. For instance, to improve customer service, many providers are investing in virtual assistants such as Chatbots. Chatbots are not AI directly, however, they utilize the power of AI and they represent a simple example to implement in any customer service department that has the potential to drastically improve the communication with customers, the automation of simple requests/ inquiries, and the proper funneling of customers to human representatives when needed.
How Insurance Providers Use ML
A good example of ML implementation among Insurance Providers is the addition of Machine Learning to predict premium prices and losses from their policies. Detecting potential risks early on in the underwriting process allows insurance to make better use of an underwriter’s time. Additionally, improving this process using ML gives insurance companies a huge competitive advantage by providing better policies and saving them money.
Benefits of AI and ML for Insurance Teams
AI helps humans and businesses pull insights from a vast amount of structured and unstructured data sources to implement intelligent solutions that save insurance providers time, money, while improving service for customers. When looking for a cost-effective way to elevate business operations and customer care, insurance companies should consider AI and ML because of the value these solutions deliver for the effort.

I’m sure many of you have heard the phrase “Internet of Things” (IoT) being tossed around recently. Basically, IoT is a network of interconnected devices that can communicate with one another. If a device has WiFi capability and sensors applicable to the device’s purpose, that device is able to be part of IoT.
As you dive deeper into the wonderful world of IoT, you will quickly discover that not all devices that are marketed as “smart devices” will be compatible with one another. Some of you may have discovered this with the Amazon Echo system. The Echo uses Alexa, their natural language processor, to accept spoken commands to control connected devices.
CNET put together a list of devices that are compatible with the Echo. You might notice that many of these devices are either made by Amazon or have “Alexa” in the description. This means the Echo is leaning towards being a proprietary device, it favors items that are made and specifically designed for its own system. Many companies do this, not just Amazon. Hopefully cross-compatibility will be more popular eventually, but not just yet.
Long story short, as you’re incorporating IoT devices into your home or library, choose a reasonably priced brand, then carefully check compatibility with your chosen brand before making any purchases. A little prior planning can go a long way to save time and money!

Electrical problems are always frustrating, but when you’re checking them, make sure you start with the basics, namely the fuses. Now if you’re in the habit of checking fuses using a test light, be very, very careful if you have a late model car. Make sure your test light is computer safe because some of these fuses will be hooked directly to electronic components, and the wrong test light will cost you a bundle. All right, there’s an easier way.
This is a Smart Glow Fuse, and you see this little bump on the top of it? Well, if the fuse blows, and we’ll hook it to this 9-volt battery, you can see that the little bump is actually a bulb and it glows. So all you have to do is look for glowing fuses and replace them. Actually I’d replace all of the fuses in my car with these Smart Glow Fuses because they’re so easy to check.
Of course with anything electrical you need a good power source, and that means the battery. Your battery cables have to be kept clean and tight. That means coating them with a protective coating and cleaning them. Also use felt pads that go between the battery cables and the battery. They’re treated with a chemical that helps reduce the formation of corrosion. But even so, sooner or later you may have to replace a battery cable.
Now, you can go out and buy the entire cable. Well, that’s going to be good, but on some cars it’s going to be very expensive. Now, here’s a mistake that a lot of people make. This is a temporary battery cable end. It goes on to the end of the battery cable. You cut the old one off and then tighten it on there, and a lot of people leave it on there. Bad idea. It is emergency use only.
But here’s something that isn’t. This is Centerpin Technology. These are permanent replacements that are actually an upgrade above and beyond what comes with the cable originally. What this does is it has a pin, a sharp pin that goes into the end of the cable. Then it has these teeth and a collar. You tighten down the collar. It presses these teeth into the cable, making a good, strong, waterproof, fume-proof, electrical connection. Extremely good.
Take care of the battery, take care of the fuses, you won’t have problems with the electronics on your car.

Processor (Central Processing Unit, CPU) - this is an electronic unit that executes machine instructions and is the head of the hardware component of a computer.
The processor can be designated as chip, located on the motherboard by connecting to a special connector or directly unsoldered on the board.
Today the processor is an integral part of any personal computer or mobile device.
For an ordinary user, the processor is of no interest without additional devices that provide power to the device (power supply), data storage (hard disk, memory drives), data input (mouse and keyboard, touch screen), data output (monitor) and so on.
Based on this definition, we can conclude that the processor differs from the computer (system unit) in a smaller breadth of the concept and the presence of an independent functional component.
Computer (system unit) - physical platform for creating a computer machine.
Simply put, the system unit is called metal box, in which the computer components are located. Organic glass, plastic, wood and so on can also be used for modding purposes.
The system unit without the computer components is called case.
By citing the simple the difference between the computer and the processor, we can emphasize the fact that the processor is just included "stuffing" of the complete computer.
If it comes to a conversation that a computer is required to repair or install software, then it is true to use the term "computer (system unit)", and not "processor".


Last week I joined the company of about a million others and became the proud owner of a Raspberry Pi. I got it just for fun; write some software and maybe make use of the GPIO ports.
I already knew I wanted to do something Eclipse related with this quite capable device, so why not run Eclipse Orion (Tools for the web, on the web) on it? During my research I discovered that someone already did that. Ken Walker of IBM Canada/Orion Project even demonstrated such a set-up as a teaser for a talk at last year´s EclipseCon Europe. Now he used the Node.js port of Orion – I had in mind to use the full package. Note that Ken also has a talk on the subject at this year’s EclipseCon in Boston.
Support for software floating point is required for Java; so we have to pick a Linux distribution that provides this. The Soft-float Debian “wheezy” is a good choice. Note that I had trouble getting the image downloaded from the torrent to work. The direct download of the zip file was OK. Compare the SHA1 hashes to make sure.
torkild@Isis:~$ openssl sha1 Downloads/2012-08-08-wheezy-armel.zip
Now we need to write the disk image to the SD card. First you must figure out where the card is mounted. On my MBP this is /dev/disk2. We must first unmount it. Note that these instructions are for OS X, if you’re on Linux there are some differences. If you’re on Windows you’re on your own. Sorry about that.
torkild@Isis:~$ diskutil unmountDisk /dev/disk2
We can now write the image. Execute the command below and be prepared to wait for quite a while. All depending on the performance of your SD-card.
torkild@Isis:~$ sudo dd bs=1m if=Downloads/2012-08-08-wheezy-armel.img of=/dev/rdisk2
When done, insert the SD-card, connect the Ethernet cable and USB power. The green LED should start blinking and after a while all LEDs should be on. This means you should be able to log into a shell on the device. First you need to figure out it’s IP-address. You can do this from the terminal if you have a screen and keyboard hooked up. I used the nifty iNet iOS application for that and found 192.168.1.105.
torkild@Isis:~$ ssh -l pi 192.168.1.105
Enter the default password (“raspberry”) and you should be greeted with a welcome message. The shell prompt will also change, indicating that you’re now logged in as pi on raspberrypi. We should start with some initial setting up.
Now, would it not be nice if we could access the Raspberry Pi without having to remember it’s IP-address (and without having to set up a DNS server)? We can do this by making use of multicast DNS (mDNS).
pi@raspberrypi ~ $ sudo apt-get install avahi-daemon
Now the Raspberry Pi can be accessed using it’s name. Try it:
torkild@Isis:~/git$ ping raspberrypi.local
PING raspberrypi.local (192.168.1.105): 56 data bytes
64 bytes from 192.168.1.105: icmp_seq=0 ttl=64 time=52.174 ms
64 bytes from 192.168.1.105: icmp_seq=1 ttl=64 time=1.380 ms
Upgrade software and kernel
Things move fast in the open source world so the software that comes with the Raspberry Pi is unlikely to be up to date. Hence we should upgrade to the latest version of both the software and the kernel.
pi@raspberrypi ~ $ sudo apt-get update
pi@raspberrypi ~ $ sudo apt-get upgrade
Expand root partition
In order to make more room we can make the root partition expand to fill the entire SD-card, start
expand_rootfs then exit and reboot.
pi@raspberrypi ~ $ sudo shutdown -r now
Wait a bit and log in again. The root partition should be much larger than the 1.8GB default.
pi@raspberrypi ~ $ df -h
Filesystem Size Used Avail Use% Mounted on
rootfs 15G 1.4G 13G 10% /
If you got your Raspberry Pi recently you probably have one with 512MB RAM, but all of that memory is not necessarily available. Check the memory chip to see which type you have and run
free -h to see if the memory is there. My Raspberry Pi is a 512MB variant, but reported only 231MB available. In order to fix this we need to update the firmware. Thankfully we can make use of a nice script to do this.
pi@raspberrypi ~ $ sudo -i
root@raspberrypi:~# rm -rf /boot/*.elf /boot/*.bin /boot/*.img
root@raspberrypi:~# apt-get install git
root@raspberrypi:~# wget http://goo.gl/1BOfJ -O /usr/bin/rpi-update && sudo chmod +x /usr/bin/rpi-update
As we’re going to use the Raspberry Pi without a graphical user interface it may be a good idea to limit the GPU memory to 16MB, this will allow applications to use more. Edit
/boot/config.txt and add
gpu_mem=16 to the bottom of the file. Now we need to restart again. After the device has booted we should see a lot more memory.
pi@raspberrypi ~ $ free -h
total used free shared buffers cached
Mem: 485M 74M 411M 0B 10M 31M
-/+ buffers/cache: 32M 453M
Swap: 99M 0B 99M
At this point we’re ready to start installing the additional stuff. The Oracle download pages have been cleverly designed so that they are pretty impossible to use with a command line client. Hence you’ll have to pick the archive using your favourite web browser and transfer it to your Raspberry using SSH. Download the Java SE Embedded 7 , EABI, VFP, SoftFB ABI, Little Endian version and transfer it.
torkild@Isis:~$ scp Downloads/ejre-7u10-fcs-b18-linux-arm-vfp-client_headless-28_nov_2012.tar.gz email@example.com:~/
You should know how to log into the Raspberry Pi by now. Do that again (unless you’ve cleverly kept the terminal window open) and execute the following:
pi@raspberrypi ~ $ tar -xvzf ejre-7u10-fcs-b18-linux-arm-vfp-client_headless-28_nov_2012.tar.gz
pi@raspberrypi ~ $ sudo mv ejre1.7.0_10 /usr/local/
pi@raspberrypi ~ $ sudo ln -s /usr/local/ejre1.7.0_10/bin/java /usr/local/bin/
pi@raspberrypi ~ $ sudo ln -s /usr/local/ejre1.7.0_10/bin/keytool /usr/local/bin/
pi@raspberrypi ~ $ java -version
The last command should reveal something like this:
java version "1.7.0_10"
Java(TM) SE Embedded Runtime Environment (build 1.7.0_10-b18, headless)
Java HotSpot(TM) Embedded Client VM (build 23.6-b04, mixed mode)
Installing Eclipse Orion
Eclipse Orion can be found at the projects website. I picked the 1.0 release for 32-bit Linux and downloaded it to my workstation. Use scp again to copy it to your home folder on the Raspberry Pi.
Eclipse Orion can launch stand-alone websites, which is quite useful for testing your work. However we need to use virtiual host names for these sites. This is done by setting the
orion.site.virtualHosts property in the server configuration file. Create a file named
orion.confand add the following:
All sites will now be created on the form
.raspberrypi.local. We’re going to start the “Hello World” example project so we’ll need a CNAME alias for this:
pi@raspberrypi ~ $ sudo apt-get install python-avahi
pi@raspberrypi ~ $ sudo wget https://gist.github.com/raw/4645066/64b8ad371b0cad5784e162b8382de0d4786317e6/avahi-alias.py -O /usr/local/bin/avahi-alias.py && sudo chmod a+x /usr/local/bin/avahi-alias.py
pi@raspberrypi ~ $ avahi-alias.py hello.raspberrypi.local &
Now we’re ready to start Eclipse Orion
pi@raspberrypi ~ $ unzip eclipse-orion-1.0-linux.gtk.x86.zip
pi@raspberrypi ~ $ java -jar eclipse/plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
It will take some time to start. When everything looks good, open your web browser and enter the address to the running Eclipse Orion instance. It’s running on port 8080 (http://raspberrypi.local:8080/). You should be greeted by a welcome page. Create an account and log in.
Click Sample HTML5 Site and leave the defaults as they are. Simply click Submit in the dialog that pops up. Now go to Sites and create a new site. Name this one “hello” and add the “Hello World” project to it. You can now start the site and view the example project using http://hello.raspberrypi.local:8080/index.html.
That was fun! Now it’s time to read getting started with Orion…

The number of computer networks is increasing dramatically. From small offices to entire countries, computer networks have become the heart of electronic communication today. Using established protocols, these local and wide area networks have become the conduit for servers and clients. Of interest today is data integrity and security as well as the “right” to the information communicated
Identify some contributors to networks and relate their achievements to the knowledge area; identify some components of a network; name some network devices and describe their purpose; describe advantages of a star topology over a ring topology; describe advantages of a ring topology over a star topology; define the meaning of a protocol; explain the importance of security when dealing with networks; and describe how computer engineering uses or benefits from networks.· Understand fundamental concepts of networks and their topologies; and understand the concept of network architecture and its hardware components.· Demonstrate understanding of the elements of a protocol, and the concept of layering; recognize the importance of networking standards, and their regulatory committees; describe the seven layers of the OSI model; compare and contrast the OSI model with the TCP/IP model; and demonstrate understanding of the differences between circuit switching and packet switching.· Understand the basic concepts of LAN and WAN technologies and topologies; demonstrate understanding of different components and requirements of network protocols; demonstrate understanding of basic concepts of error detection and correction at the data link layer and below; and design and build a simple network by implementing (and designing) a simple network protocol that operates at the physical and data link layers of the OSI model.

This small but important part is typically made of brass or copper and is screwed onto the positive battery terminal. Its purpose is to create a barrier between the terminal and any moisture or other contaminants that could cause corrosion, which can lead to poor electrical connections and even battery failure. The Corrosion Resistor Head is an essential part for maintaining proper electrical function in a truck and ensuring long-term reliability.


From 2015 to 2017, Apple has filed several patents related to augmented reality tech and its rumored iGlass program. The iGlass is, hypothetically, a pair of augmented reality glasses. The first designs would rely on wireless connectivity to an iPhone to function: the iPhone would handle the heavy lifting, but the glasses provide an innovative AR display that interfaces with the world around you. However, later designs might replace iPhones altogether. Let's deduce what kind of world that would be.
All Glasses Will Become Hipster Glasses
Everyone knows that certain glasses frames are 'hipster glasses.' However, with all Apple fans wearing glasses, it seems that the entire population of glasses-wearers will grow to be associated with Apple fanatics and brand loyalists.
Glassing While Driving Laws
If you thought texting and driving was an epidemic, just imagine people being able to watch reruns of Friends with nothing but a pair of glasses. Enforcing anti-Glassing laws will be a challenge, though; it's easy to imagine a world where people with normal glasses are often pulled over on the grounds of DWB (Driving While Blind). Dark days are ahead for the vision-impaired.
This sort of tech that blurs the line between man and machine really gets everyone's inner doomsday theorist going. It's easy to imagine Apple utilizing such a close connection to users to indoctrinate them with subliminal messaging and coded waves to create a class of obedient serfs who exist to consume Apple products year after year. After all, how else could Apple convince people to... buy the same phone year after year?
Overall, Apple's innovative iGlass project promises an interesting and exciting future for this unproven technology. If anyone can make a technology like this work, it's Tesla. But if anyone can mass-market it, that is surely Apple. I for one welcome our new corporate overlords.


Cat5e vs. Cat6 vs. Cat6a: It's Mostly About Speed. Installation is $50 per connector, which makes the cost of wiring a home for CAT6 around $700 and CAT6A around $850. Cat6A is the newest iteration and utilizes an exceptionally thick plastic casing that helps further reduce crosstalk. As the above chart illustrates, Cat6a cables support high-speed data transfer over longer distances than Cat6 cables. For Cat6 cables, maximum lengths depend heavily on network speeds and crosstalk conditions. Cat 6a and Cat 6 are also obtainable in Stranded wire vs. Therefore, Cat6a takes more space in a patch panel than Cat6. For example, in lower speed networks such as 10, 100, or 1,000 megabit systems (the 10/100/1000BASE-T standards), the maximum cable length is 100 meters (330 feet), with about 90% of that length used to transmit data between systems and the remaining 10% for the connection itself. Also, CAT6 cable can reach 10-Gigabit Ethernet speeds by reducing the length to less than 50 meters. Cat 5e vs. Cat 6 vs. Cat 6A - which should you choose? As for cable price of Cat6 vs Cat7, Cat7 cable is more expensive than Cat6 cable if they are compared under the same conditions. CAT6A cables transmit up to 500 MHz, which is … All copper wires, ranging from 8 – 10 per cable, are tightly wound to ensure that the chances of crosstalk are reduced. Extra shielding helps boost reliability and block out interference in areas that may suffer from heavy electromagnetic interference (EMI). The cost differences between Cat6 and Cat6a cables are relatively small, around 20-35%. The latter meets the UL910 standard, which is the strictest standard, thereby, making the cat 6 plenum cable the most required. For these sorts of applications, Cat6 may have some value. Now that we are settling into our new home one of my first projects is to get some networking run and move a couple coax lines. Cat6a cables are also a future-proof solution that can handle network upgrades. Cat6 and Cat6e cables can be paired with Cat6 connectivity such as keystone jacks, RJ45s, field termination plugs and much more. We all use ethernet cables in our homes and at workplaces. 4. In other words, it is important not to bend cables too much, as this can damage wiring and decrease performance quality. Cat6 cable is still seen as the basic standard for any new installation in the majority of standard office and building space. Of course, Cat6a would be even better but Cat6a is relatively new and the price jump between Cat6 and Cat6a is much steeper than the difference between Cat5e and Cat6. All Rights Reserved. increased 0.1 inches, from 0.25 inches to 0.35 inches. The bend radius is roughly four times the cable diameter. In this case, Cat6a (“a” here standing for “augmented”) is a better cable than the original Cat6. CAT6A is capable of supporting data transfer rates of up to 10Gbps at a maximum bandwidth of 500MHz. When CAT6 was first introduced it was approximately 50% more expensive than CAT5E, which made it cost prohibitive for many installations. Cat6a is capable of supporting data transfer rates of … That’s smaller than the smallest CAT6A UTP cable. Cat6 cables were created under a more exacting standard than previous versions of Ethernet cables to facilitate data transmission speeds of up to 10 gigabits per second (10 Gbps). Het verschil tussen een Cat6 en een Cat6a kabel zit hem met name in de snelheid waarmee de kabel data kan overbrengen en daarnaast volgt het verschil in bandbreedte.

The full HD, energy efficient monitor that’s nice to look at and even better to use.
With even further improved energy efficiency, and an even thinner bottom bezel, the EV2451 combines space saving with energy saving.
Ultra-Thin Bezels on All Four Sides
The monitor features 1 mm ultra-slim bezels on the sides and top with black borders of 4.3 mm. Electrostatic switches are placed on the front of the monitor for easy adjustment of monitor settings. Furthermore the bezels are flush with the screen surface, making a completely flat screen perfect for multi-monitor configurations.
Say Goodbye to Tired Eyes
Due to the way brightness is controlled on LED backlights, a small number of people perceive flicker on their screen which causes eye fatigue. The FlexScan EV series utilizes a hybrid solution to regulate brightness and make flicker unperceivable without any drawbacks like compromising color stability – even on low brightness settings.
Significantly Reduce Blue Light
In the visible light spectrum, blue light has wave lengths adjacent to ultraviolet light. Compared to the factory preset setting of 6,500 K of typical LCD monitors, Paper Mode is closer to the spectral distribution with long reddish wavelengths so it reduces the amount of blue light, a cause of eye fatigue, and helps prevent eyestrain when reading documents.
Smooth Color Gradations
The monitor produces smooth image display by taking an 8-bit signal (256 tones per RGB) and selecting the optimum color values from a 10-bit look-up table (1,021 tones). Also, each monitor is adjusted on the factory line to minimize variability between units.
Maximum Energy Savings
The FlexScan EV2451 typically consumes just 13 watts, earning it the EU Energy Label maximum rating of A++. What's more, all models are certified for visual ergonomics and energy savings.
Auto Brightness Control
To prevent eye fatigue, a brightness sensor called Auto EcoView detects the changes in the ambient brightness that occurs throughout the day and automatically adjusts the screen to the ideal brightness level.
Advanced Settings for Auto EcoView (Auto Brightness Adjustment)
1% - 100% Brightness Range
In a dimly-lit work environment, a monitor with low brightness settings is more comfortable to use. With its LED backlight, the monitor is adjustable to approximately 1 cd/m² which is less than 1% of the maximum.
Clear View from All Angles
The monitor uses an LED-backlit IPS (in-plane switching) LCD panel with 178° viewing angle that minimizes color shift and contrast changes when viewing the screen at an angle. This means that two people sitting at the one computer can easily see the screen – and it also makes the EV2451 perfect for multi-monitor configurations.
White on White
The aesthetically-pleasing design of the monitor extends even to the cables. White cables come bundled with the white cabinet; and black cables with the black cabinet version of the FlexScan EV2451. Additionally the attached Cable Cover removes the potential eyesore of tangled cables by holding the cables neatly behind the stand.
New Stand Design
The EV2451 comes with our latest stand design. It boasts greater height adjustment, and due to the tilted design has a base 43 mm smaller than previous stands giving you more space at your work station. Furthermore, the stand comes attached in the box – simply pull it out, plug it in – no stand setup required.
Greater Height Adjustment
EIZO Monitor Configurator for Administrators
EIZO Monitor Configurator lets system administrators control the settings of all FlexScan EV monitors with a USB connection. The settings of one monitor can be saved as an xml file and applied to other monitors via USB or office network.
EIZO’s Screen InStyle is a newly developed software that allows you to easily manage multiple monitor settings such as power, color, brightness and gamma. But what makes Screen InStyle truly unique is that it allows you to manage multiple connected monitors from the one place – meaning that settings placed on one monitor are automatically applied to all connected monitors.

LED Backlight - Less Power, Longer Life
Compared to CCFL backlights, LED backlights last longer and consume less power. They are also mercury-free for minimal environmental impact.
Zero Bright Pixels
EIZO guarantees this product will be free from bright sub-pixels for six months from purchase date.
See our Bright Pixel Policy for details
A manufacturer’s 5-year warranty covers all components including the LCD panel to ensure a long service life. This warranty is 2-years or 67% longer than the standard 3-year warranty of most monitor brands for significantly lower running costs.
Mini PC Stand Bracket
The EV2451 can be equipped with a special VESA adapter called ‘PSCK-03’ which a mini PC or thin client can be mounted to. This accessory fits on the rear of the stand and does not affect the stability of the monitor.
Mounting a mini PC or thin client on the rear of the monitor clears up desk space and neatly hides your PC from view.


The MA850 is a member of the long line of Knoll multichannel amplifiers. Designed primarily for the custom install industry, it is used to power speakers with different or similar sources in multiple rooms. With eight channels rated at 50 watts per channels at 8 ohms, the MA850 packs some serious punch. Each channel has a gain control. The MA850 can be turned on and off via the front panel power switch or via the 12 VDC trigger. MA850 channels 3-8 can be linked to channel 1- 2 individually using the link switches. MA850 amplifiers designed to meet the amplifier needs of custom installed systems where highquality sound is a specific requirement.
1.Size efficiency.The MA850 consists of a total of 8 power amplifiers in one 3-1/2” high enclosure. Each power amplifier channel can deliver 50 watts RMS into an 8-ohm load.
2.Automatic protection circuitry.Each MA850 channel is individually and fully protected against low impedance, overheating, overloading, overvoltage and undervoltage. The protection circuitry automatically restores the amplifier channel as soon as its parameter returns to the safe operating area.
3.Individual input gain adjustment.Each channel features an input gain adjustment pot to adjust each channel for gain and speaker sensitivity variations. The gain adjustments are on the rear of the MA850 so installers normally set the gain.
4.External power on/off.The MA850 can be turned off and on by external controllers. To activate external power on, apply a 12 VDC current to the trigger jack (the MA850 power switch is in the off position for external power control).
5.Stackable 17" chassis.
6.Link Feature.Certain installations require that some or all of the stereo channels play the same content. Instead of using Y cords, "link" cascades any or all of channels 2-4 to channel 1 (l/r).


A computerized tomography (CT) scan combines a series of X-rays taken from different angles to make detailed picture of a part of your body, for example, organs, blood vessels, bones and the spinal cord. To have the scan, you lie down on a table attached to the scanner, which sends X-rays through the body part being studied. Each scanner rotation takes an image of a thin slice of the body part, and then all of these images are combined and can be printed. The scan is used both for diagnosis and to plan medical, surgical or radiation treatment.
Magnetic resonance imaging (MRI) uses powerful magnets, radio waves, and a computer to take detailed images of a body part such as organs, tissues and skeletal system. Unlike a CT scan, or x-rays, an MRI does not use radiation. The scan can be used both for diagnosis of an illness or injury, and to monitor how well you are responding to treatment.
Ultrasound uses sound waves to create images of a body part. To form an image, an instrument called a transducer sends out high-frequency sound, and then records the echoes as the sound waves bounce back. This helps to determine the size, shape, and consistency of soft tissues and organs. The information is relayed to a computer screen in real time. The image created is used to diagnose conditions and to guide doctors through medical procedures.


5. How do I know if my device is Wi-Fi enabled?
Most current laptops, tablets and smartphones support WiFi, however, you should refer to your device’s User Manual to verify WiFi compatibility. To determine if your device is Wi-Fi-enabled, you may open the device's connection manager – which is an application used to modify the device’s network connections – and see if there is a reference to WLAN (wireless local area network), Wi-Fi or 802.11. Typically the connection manager is located in a settings or applications folder. Your device must support any one of the 802.11 a/g/n/ac standards.

This post is about ElectroBOOM's disagreement with Walter Lewin. Spoiler alert: both are right under their respective premises, both sides misrepresent the other side. The misrepresentation is implicit in ElectroBOOM's video, which ignores the objective of Lewin's experiment. ElectroBOOM raises a valid point, but is dismissed by Walter Lewin as incompetent. This is unfortunate since a response to ElectroBOOM's video complements Walter Lewin's demonstration, provides further insight into the underlying physics, and is an opportunity to discuss some misconceptions about Faraday's law.
The debate is about Lewin's demonstration in his MIT lecture 8.02–16
, which is based on an article by Robert H. Romer
. Voltmeter measurements on a simple electric circuit surrounding the changing magnetic field of a solenoid are predicted and experimentally verified. It is concluded that the electric potential between two points in the circuit is undefined, and that the loop integral over the electric field along the circuit does not vanish. For the history behind the experiment see the extensive references given in Kirk McDonald's notes on Lewin's experiment
Measured voltages between two points in the circuit are well defined when we take the effect of the induced electric field on the probe wires into account. Kirchhoff's voltage law still holds for these voltages.
Lewin and ElectroBOOM use different versions of Kirchhoff's law. Lewin's version is the condition for conservative fields that the loop integral over the electric field vanishes. It is Faraday's law for the special case of a constant magnetic flux through the loop. In accordance with Lewin, I will call this version Kirchhoff's loop rule (KLR).
ElectroBOOM's version is the one given in Feynman's lecture notes for AC circuits
(including the special case of steady currents), which sums over voltages (including electromotive forces) that are measurable with a voltmeter over the circuit elements. I will call this version Kirchhoff's voltage law (KVL).
Lewin calls KVL a reformulation of Faraday's law that is done to make it look like KLR. Lewin seems to have a strong opinion about his claim that KLR is the only real Kirchhoff's law. I think it is safe to say that only KVL is relevant for applied circuit analysis. I would like to see a justification for the idea that KLR is used anywhere outside some elementary textbooks. Kirchhoff's original publication
mentions only voltages over batteries and resistors, and is therefore a special case of both KVL and KLR, although his formulation involves no line integrals and is closer to KVL. Remarkably, Kirchhoff (correctly) calls the voltage over a battery an "electromotive force" (emf). This is consistent with KVL, but inconsistent with Lewin's (correct) use of the term "emf" for the induced emf in his circuit. This emf does not enter his KLR.
The lumped element model
KVL is formulated for the lumped element model, which assumes that changing magnetic fields are well contained inside the circuit elements. This assumption is obviously not fulfilled for Lewin's circuit, but it should also be obvious that the effect of the external magnetic field on the circuit in this case is equivalent to that of a series of secondary coils of a transformer, distributed over the circuit. KVL still applies and the only problem is the measurement of the voltages with probe wires influenced by the uncontained induced electric field.
Lewin's experiment explained with Faraday's law
In Lewin's experiment, the voltage over a resistor is measured with a measurement loop that has a vanishing magnetic flux. Faraday's law implies that the measured voltage must coincide with the voltage drop over the resistor, because it is the only element in the measurement loop and the resistance of the wires can be neglected (the total electric field inside an ideal conductor is zero). Note that the induced electric field surrounding the solenoid is irrotational in a simply connected region containing the measurement loop (for example everything left to the solenoid), so we don't worry about undefined voltages.
The voltages for both resistors in this circuit is measured this way and the results are −0.1V and −0.9V for a chosen orientation of the circuit loop. These results coincides with the prediction from Faraday's law for the circuit loop. It predicts that there is a total induced emf of 1V and with Ohm's law the current and the individual voltage drops over the resistors can be calculated. We conclude that the loop integral over the electric field along the circuit is −0.1V+(−0.9V)=−1.0V and KLR does not hold.
KVL still holds for Lewin's experiment
KVL takes all voltage drops and electromotive forces in the circuit into account, so we have −0.1V+(−0.9V)+1.0V=0V. Up to here all possible disagreement should be only due to a difference in terminology.
Measuring electromotive forces
For the lumped element model we have no problem measuring the voltage drop over an inductor. The voltmeter reading gives us the emf in the inductor. In Lewin's experiment, the emfs is distributed over the circuit and when we try to measure the emf in a segment of the circuit, we have the problem that there is also an induced emf in the probe wires that contributes to the measurement. In fact, Faraday's law tells us that in Lewin's measurement the emf in the probe wires must cancel the emf in the probed circuit segment, so the emf in the circuit segment remains invisible.
In order to measure the emf (together with the other voltage drops) in the probed circuit segment, we have to arrange the probe wires so that the total emf in both wires is zero. If we can achieve this, then the voltmeter reading gives us the voltage over the circuit segment that enters KVL. We can not do that without additional information about the induced electric field. This is a crucial difference from Lewin's measurement. Lewin only needs one of Maxwell's equations (in its integral form) to predict and understand his measurements. ElectroBOOM needs some details about the solution of Maxwell's equations for the induced electric field. Lewin only needs loop integrals over the electric field, ElectroBOOM needs the induced field vector for every point along the probe wires in order to calculate the emf as the line integral along the wires.
Fortunately, the induced electric field of a solenoid has simple geometric properties that can be exploited to find a proper arrangement of probe wires. Since we know that the field lines are concentric circles around the axis of the solenoid , we also know that the field is perpendicular to every plane that contains the axis. Let's call these planes "zero flux planes" (they happen to have zero magnetic flux everywhere). A probed point on the circuit is contained in exactly one zero flux plane. If we run the probe wires from the probed points inside their respective zero flux plane until they meet on the axis, we know that the emf in both wires is zero everywhere up to the meeting point (the wires are perpendicular to the induced electric field). From the point on the axis where they meet onward, the two probe wires shall follow the same path, so that both contributions to the total emf cancel (alternatively choose a meeting point far away where the field can be neglected). Examples for such measurements have been conducted by Cyriel Mabilde:
(See also the measurements by Dirk Van Meirvenne
Can the electromotive force be localized and what does a voltmeter measure?
[This section is somewhat speculative. Comments and criticism are welcome.]
The title of Romer's article poses the question 'What do "voltmeter" measure?', and he gives the answer that a voltmeter measures the line integral over the electric field along the probe wires through the voltmeter itself. For ideal probe wires this amounts to "a voltmeter measures the voltage inside of it". I will make the case that this unsatisfactory answer is related to Romer's unexplained claim that the question "Where is the emf located?" is poorly defined. As we can clearly see, Romer's approach is at odds with our measurements of emfs over wire segments, which gives us information over the local distribution of the emfs in the circuit.
We have defined the emf in a wire segment as the line integral over the induced electric field along the segment. This is in accordance with the definition of the emf as it is used in Faraday's law, but note that the integral in Faraday's law is usually over the total electric field, which includes the conservative field coming from the charge distribution in the conductors. The contributions from this field do not cancel if we don't integrate over a loop. This field is not the source of an emf, so it must not be taken into account when calculating the emf in a wire segment.
This definition is consistent with the results of voltage measurements over inductors in the lumped element model, which localizes the emf in a lumped element. We have also seen that local emfs can be consistently applied to Lewin's circuit to predict measured voltage drops over wire segments to check KVL. Together with the fact that the emf is caused by the effect of the induced electric field on the charges inside the conductor, which is defined in local terms, this gives us reason to believe that we are dealing with a well defined physical quantity.
There is an objection to our method of observing local emfs that will make us take a closer look at how to define and observe them. If one is used to rely only on Faraday's law to predict and explain measurements, one might be under the impression that the emf is only defined as a property of a loop and cannot be localized. In fact, every measurement of local emfs we have described above can be explained in terms of magnetic flux changes and loop emfs. Apparently, voltmeter measurements alone cannot help us to convince a strict follower of Faraday's law that local emfs represent an underlying reality.
The electric field on the inside of an ideal wire is assumed to be zero, any deviation from zero is compensated (almost) instantly by a rearrangement of charges inside the wire. In the presence of an induced electric field we should see the corresponding emf represented in the charge distribution. On the outside of the wire, the charges create a measurable electric field that can be probed with a fieldmeter. In the case of Lewin's circuit, where ideal wires connect resistors, we expect to observe a change of field strength along the outside of the wires. The size of the local emf in a short piece of wire is determined by the rate at which the field changes as we go along this piece. This can be considered a continuous version of more familiar emf sources like batteries, where we observe a jump in charge density over the electrodes. With this insight, we can understand the definition of the electromotive forces in an ideal wire segment as the line integral over the negative of the electrostatic field of the charges, as it is given, for instance, by Reitz, Milford, Christy, Foundations of Electromagnetic Theory, 1960, p. 135, see also the Wikipedia definition
(which doesn't give a valid source).
Considering the field of the charge distribution also gives us a answer to the question what a voltmeters measures. An answer should describe a physical quantity that is a property of the circuit alone and exists independently from the measurement device. It must be measurable by a voltmeter without disturbing the probed system. Feynman's derivation of KVL
gives us the hint that the voltmeter reading is given by the line integral over the electric field of the displaced charges near the surface of the wire where the probes are connected. This field is the only contribution to Feynman's loop integral over the electric field along the circuit. When we connect the probe of a voltmeter to the circuit, it becomes an extension that transfers the field to the inside of the voltmeter where it is compared to the field coming form the other probe. (Note that Feynman's loop integral applied to Lewin's circuit has a contribution from the induced electric field surrounding the circuit. This contribution accounts for the induced emf in the circuit, which is not represented by a lumped element.)

Apple launching 3 new iPhones, a watch with a larger screen & updated iPad Pros say Bloomberg.
The tech world is waiting for Apple to announce the latest batch of iPhones that will likely be sometime in the second week of September (the company’s usual announcement date), and rumours so far have been consistent, suggesting Apple are launching three new devices.
Bloomberg’s Mark Gurman and Debby Wu are saying that some inside Apple are calling this another “S year” so the new phones will look the same, but update the internal powerhouse.
Here’s an overview of Bloomberg’s rumours:
- Three new iPhones. An upgraded iPhone X with a 5.8-inch OLED screen; new high-end iPhone with a 6.5-inch OLED screen and a new cheaper model with a 6.1-inch LCD screen.
- Cheaper and colorful. The 6.1-inch iPhone will come in different colors.
- Gestures. All 3 devices will have the new gesture controls introduced in the iPhone X, and Apple’s face ID unlocking system. Possibly allow for side-by-side view allowing you to view 2 apps at the same time such as Mail and Calendar.
- Naming. The new high-end device might be “the iPhone Xs” with the larger device “the iPhone Xs Plus.”
- Peripherals and more. Some time this year (not necessarily in September) we can also expect updated AirPods; a new Apple Watch with a larger screen in the same body; a new wireless charger (probably the much-delayed AirPower mat); and upgraded iPads Pros with slimmer bezels and Face ID replacing the fingerprint-sensing home button.
