Vernier caliper list count According to science formula

Theory :  Principle of vernier calipers – N divisions on the vernier scale is equal to (N-1) divisions on the main scale.

N V.S.D = (N-1) M.S.D

1 V.S.D =  M.S.D

Least count (L.C) of vernier calipers : Minimum length or thickness measurable with the vernier calipers is called its least count.

Least count (L.C) = 1 M.S.D – 1 V.S.D

L.C = 1 M.S.D –  M.S.D

L.C = 1 M.S.D [ 1-]

L.C =   = 

Where S is the value of  one Main scale division and N is the number of equal divisions on the vernier scale.

The least count of the vernier can be measured by using the formula stated below. 

Least count (L.C) = 1 M.S.D - 1 V.S.D
Example; 
vernier scale is constructed by taking 49 main scale divisions dividing them into 50 divisions

ie. 49mm divided into 50 parts

therfore

1 vsd=49/50 mm=0.98mm

1 MSD=1mm

Substituting in formula

L.C = 1 M.S.D - 1 V.S.D

L.C=1-0.98=0.02mm

Best tricks my internet speed increase on windows

1.This is For Vista/Win7 TCP Window Scaling Auto Tuning Slow Down Network Performance

--------------------------------------------
To change the value for Receive Window Auto-Tuning Level parameter in Vista, run elevated command prompt, and then type in one of the following commands, depending on your preference how you want Vista to use the RWIN size.

netsh interface tcp set global autotuninglevel=disabled

Disable the autotunning feature in Vista completely, and fit and lock the RWIN receive window to default value 65536 bytes.

netsh interface tcp set global autotuninglevel=highlyrestricted

Allow for the receive window to grow beyond the default value, but do so very conservatively. In this mode, Vista will by default use RWIN of 16,384 bytes with a scale factor of 2.

netsh interface tcp set global autotuninglevel=restrictedAllow for the receive window to grow beyond the default value, but limit such growth in some scenarios.

netsh interface tcp set global autotuninglevel=normal

Allow for the receive window to grow to accommodate almost all scenarios. The default setting in Vista. Specifying this command mean you want to turn back on AutoTuning feature.

netsh interface tcp set global autotuninglevel=experimental

Allow for the receive window to grow to accommodate extreme scenarios. Note The experimental value can decrease performance in common scenarios. This value should be used only for research purposes.

Users should try out the various possible configurations for the Vista TCP RWIN Auto Tuning Level in order to get the best value that improve network performance and increase download speed.

How To install Active Directory on Windows 7 step by step

This blog post is a step-by-step guide to installing the Active Directory Tools (i.e. Active Directory Users and Computers) on a Windows 7 machine. It has been tested on Windows 7 Enterprise but will probably work with Professional or Ultimate as well - Home users it will not work (but then why are you wanting to administer AD from a home machine??!!)

First of all you need to download the software from Microsoft. In the Microsoft Download Centre these are called "Remote Server Administration Tools for Windows 7" a direct link to the download page is given below;

http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=7d2f6ad7-656b-4313-a005-4e344e43997d

If you scroll down to the "Files in This Download" section of the page you'll see two files. Depending on whether or not you're running 32-bit or 64-bit Windows 7 you need to pick the correct file. If you're unsure of which version you're running then go to the start button, right-click "Computer" and then select "Properties". You'll see something like this;

System Information (64-bit/32-bit)

Look at the "System type:" value and you'll see what version of Windows you're running.

If you're running 32-bit then you need to download the file which starts "x86..." (currently this is"x86fre_GRMRSAT_MSU.msu" but it might change). For 64-bit users you need to download the file which begins "amd64..." (currently this is "amd64fre_GRMRSATX_MSU.msu") - this is true even if you're running a non-AMD 64-bit processor. The reason for this I'll leave Microsoft to explain ...

Once you've got the file install it (it's a standard KB update file).

After it's been successfully installed go to the Start Menu > Control Panel and select "Programs";

"Turn Windows Features on or off" under "Programs and Features"

The "Windows Features" dialog box will be displayed, scroll down to "Role Administration Tools" (under "Remote Server Administration Tools") and select the the following items;

"Windows Features" dialog

Click "OK" to make the changes.

In order to make finding these under the Start Menu a little easier right-click the Start Button and select "Properties";

Taskbar and Start Menu Properties

Select "Customize ..." and then scroll down the list until you see "System administrative tools" and choose where you want the tools to display;

Customize Start Menu

Under the Start Menu you will now see an "Administrative Tools" option, under this you'll see the new AD Tools;

Active Directory Start Menu Items

NOTE: Sometimes a reboot is required to pick up these changes!

How to download free windows 8 all version

ISO images

An ISO image must be converted into installation media stored on a DVD or a USB flash drive. Instructions are provided on this page. Developer tools are available for download from Windows Dev Center.

Important: If you decide to go back to your previous operating system, you'll need to reinstall it from the recovery or installation media that came with your PC, which is typically DVD media. If you don’t have recovery media, you might be able to create it from a recovery partition on your PC using software provided by your PC manufacturer. Check the support section of your PC manufacturer’s website for more information. After you install Windows 8, you won’t be able to use the recovery partition on your PC to go back to your previous version of Windows.
