Construction of rotor in alternator is of of two types. The two main types of rotors are salient pole and non-salient pole type rotor. Non-salient pole rotor is also known as cylindrical rotor. The main difference in the rotor construction of salient pole type synchronous generator and non-salient pole type are as follows:

The company claims 2nm processors can use 75 percent less power than 7nm-based CPUs for the same performance.
The architecture can help processor makers deliver a 45 percent performance boost with the same amount of power as current 7nm-based chips, or the same level of performance using 75 percent less energy, according to IBM
IBM says it has created the world’s first 2nm chip
https://www.engadget.com/ibm-2nm-chip-power-efficiency-100001102.html
The company claims 2nm processors can use 75 percent less power than 7nm-based CPUs for the same performance.
IBM claims it has taken a major step forward in chip technology by making the first 2nm chip. The company says it has squeezed 50 billion transistors onto a chip the size of one’s fingernail.
The architecture can help processor makers deliver a 45 percent performance boost with the same amount of power as current 7nm-based chips, or the same level of performance using 75 percent less energy, according to IBM. Many 2nm-based processors will likely deliver something in between, a balance of better performance and improved power efficiency.
Mobile devices with 2nm-based processors could have up to four times the battery life of ones with 7nm chipsets. IBM claims you might only need to charge those handsets every four days. Laptops would get a speed boost from such processors, while autonomous vehicles will detect and react to objects more quickly, according to IBM. The company claims the tech will benefit the likes of data center power efficiency, space exploration, artificial intelligence, 5G and 6G and quantum computing.

The Best Protection for your Circuits? eFuse! Here is why they are awesome! EB#48
https://www.youtube.com/watch?v=JOhQ3nsR7xo
In this electronics basics episode we will have a closer look at eFuse ICs. They offer a ton of protection features for a very small price tag. That is why I will show you how I used such an eFuse in my LiPo Supercharger project and how you can use it for pretty much every electronics project. The included protection features are the following: undervoltage, overvoltage, reverse voltage, overcurrent and short circuit current. Let’s get started!

Rectangular pulse generators feature independent frequency and duty-cycle adjustment

Previously-known schemes for RC rectangular pulse generators with a regulated duty cycle had an ineradicable disadvantage: changing the pulse fill factor (D) inevitably changed the frequency of generation. I have described elsewhere generator schemes with separate frequency and fill factor control (references 1-3). Here are two new solutions to the problem of independent frequency and fill factor adjustment in RC generators.

Using higher-powered RF immunity testing
https://www.edn.com/using-higher-powered-rf-immunity-testing/
One very successful trick I use to simulate radiated emissions on the bench is to run an RF generator into an H-field (loop) probe. The best level seems to be +15 to +20 dBm. This will generate an intense RF field around the probe tip. By sweeping the probe around circuitry and interconnecting cables, I very often find I can duplicate the system failure. By identifying sensitive circuit nodes, mitigations can then be applied. I’ve solved many tough problems for my clients this way.
Normally, I’ve used the Signal Hound VSG-25A vector signal generator (to +13 dBm) or Windfreak SynthNV or SynthHD signal generators (+19 dBm or +20 dBm). All of these generators have the ability to provide 1 kHz 80% AM or 1 kHz 50% pulse modulations, which is required for the EMC test standard IEC 61000-4-3 or MIL-STD-461. I simply connect any of these to the USB port of my laptop, launch the appropriate software control, connect my H-field probe, and off we go
However, there are times when I find I need a little more RF level in order to initiate the failure mode and this generally involves adding an RF power amplifier. I’ve used an RF power amplifier a few times with good success (References 2 and 3). These amplifiers were both broadband 10 to 1000 MHz with 2-3 W output, which was able to get to a desired level for failure simulation.

Graphics card shortage: When will it end?
https://www.dailysabah.com/life/graphics-card-shortage-when-will-it-end/news
If you are considering building your own flashy PC soon, be aware that winter has already arrived, even if it’s blazing hot outside
The most basic principle of economics, the law of supply and demand, applies especially well to graphics cards at the moment. Prices have skyrocketed as stock has dried up.
The situation surrounding the video card shortage – which is so severe these days that arguments break out in tech stores that still manage to sell the product – is not just caused by the negative consequences of the pandemic itself. The current global apocalypse sure accounts for a fair share of the effect – it may even be the first reason for the shortage. But as I said, there is more to it than that.
Let’s take a look at the reasons and try to work out whether the shortage will end any time soon.
Video cards – “to the moon”
“To the moon” is like a catchphrase among cryptocurrency investors. They express their hope by saying, for example, “Dogecoin to the moon” – especially when Tesla and SpaceX mastermind Elon Musk shares a picture of his dog, live streams eating a hotdog or barks or something.
I’m all for cryptocurrencies – I’m sure they have great potential. But please, bitcoin people, don’t mess with our graphics cards.
The GeForce maker has recently announced that the global video card shortage will continue throughout 2021. What’s worse, the Taiwan Semiconductor Manufacturing Company (TSMC) and processor maker Intel also warned that the shortage may continue all the way through 2022.
Considering the state of the pandemic and these announcements by major companies, the near future seems grim to be honest. For at least a couple more years, the entry-level to mid-tier graphics card market will probably be dominated by the GTX 1030s, and high-power cards such as the RTX series will be even scarcer.
Even though the near future is not too bright, every shortage ends one way or another in this world order. As Turks ironically joke: “There is no shortage of solutions in capitalism.”
Yes, the current shortage will end too, albeit not in a very short time. Nowadays, waiting seems like the only option for gamers, besides hoping and praying.
