Customize the Manufacturer Support Info in Windows 7 or Vista.!!

By:Prayag Nao

If you have a computer with pre-installed Windows 7 or Vista, most likely you’ll notice the manufacturer’s support information when you look in the system properties window. If you’d like to customize this information or use a picture of your own in this space, you can do so easily.

Right-click on Computer and choose Properties.
Look my changed properties.

To edit the information in this screen, you’ll need to open up your registry editor and navigate down to the following key:


Note: If this key does not exist, you can download the following registry file, which you will want to edit before double-clicking to add into the registry.

You can modify the following fields and put any values you’d like into them, with the exception of the Logo key, which you probably shouldn’t change.

How does a Thermal Power Plant Work ?

By:Prayag nao

Thermal Power Plants Thermal power plants use water as working fluid. Nuclear and coal based power plants fall under this category. The way energy from fuel gets transformed into electricity forms the working of a power plant. In a thermal power plant a steam turbine is rotated with help of high pressure and high temperature steam and this rotation is transferred to a generator to produce electricity.

Energy absorption from steam When turbine blades get rotated by high pressure high temperature steam, the steam loses its energy. This in turn will result in a low pressure and low temperature steam at the outlet of the turbine. Here steam is expanded till saturation point is reached. Since there is no heat addition or removal from the steam, ideally entropy of the steam remains same. This change is depicted in the following p-v and T-s diagrams. If we can bring this low pressure, low temperature steam back to its original state, then we can produce electricity c…

How do optical mice work?

By: Prayag nao

I­t appears that the venerable wheeled mouse is in danger of extinction. The now-preferred device for pointing and clicking is the optical mouse. ­
The optical mouse actually uses a tiny camera to take 1,500 pictures every second. Able to work on almost any surface, the mouse has a small, red light-emitting diode (LED) that bounces light off that surface onto a complementary metal-oxide semiconductor (CMOS) sensor.
The CMOS sensor sends each image to a digital signal processor (DSP) for analysis. The DSP, operating at 18 MIPS (million instructions per second), is able to detect patterns in the images and see how those patterns have moved since the previous image. Based on the change in patterns over a sequence of images, the DSP determines how far the mouse has moved and sends the corresponding coordinates to the computer. The computer moves the cursor on the screen based on the coordinates received from the mouse. This happens hundreds of times each second, …
