What is the meaning of a capacitor been shorten?

A shorted capacitor is one where the gap between the plates is damaged, and the plates are touching each other, creating a short circuit.

What is the shape of the tooth of spur gear?

The shape is known as an involute

the shape is analogous to unwinding a piece of string from a spool representing

the base circle diameter of the gear, imagine your pencil at the end of the string and the string kept tight during unwinding, unwind until line meets OD of gear, then apply blend radius at base circle, then mirror about tooth centre line for full tooth profile.

What is the purpose of an auxillary view?

Fore example in engineering auxillary view show the dimensions of an object. The drawing allow to read the proportions and exact measures of it.

How do you run autocad 10 in Windows XP?

You will need to use some form of "Virtualization", such as Microsofts Virtual PC.

Can a 3-D printer use ceramic material to print with?

No, at least not at this time.

The material still has to be liquid enough to spray out of the nozzel of the printer. It's still just a glorified inkjetprinter. It probably uses a low melting point plastic like substance that gets super heated then gets shot out.

For a B tech computer science student which stream is best in MBA?

It all depends on student interest area, whether he wants to go in HR/Marketing/Finance and etc. In my opinion, it is better to go for M.tech OS MS,rahter then going for MBA.

M.tech provide variety of career options for students. MTech program in Computer Science & Engineering takes a unified approach to the design and analysis of computing structures across hardware/software, systems/applications, and theory/experiments.

a wide range of career options are available for m.tech (Cs) student such as:

Real-time and embedded systems / Information Security / Software Engineering

Connected Systems / Entertainment Systems / IT-assisted education / Computer applications in finance and commerce .

How do you calculate switching capacity of a switch?

For example you have 24port switch capable of RxTx of 100mbps.

then switching capacity is

24x100= 2400 mbps Rx plus 24x100=2400 mbps Tx .

so a total of 4800mbps which is 4.8gbps.(non blocking architecture)

Can someone do computer enginering and computer programming?

Computer engineering does require you to know how to program and your definitely going to do programming with computer engineering. As for a double major in Computer engineering and computer science, it depends on your school. But it may overlap each other a lot that it may not be offered as a double major. Ask your school advisor.

What is scope of model?

hello i discovered answer:

Assessing the scope of a model, that is, determining what situations the model is applicable to, can be less straightforward. If the model was constructed based on a set of data, one must determine for which systems or situations the known data is a "typical" set of data.

What is computer aided embroidery?

Computer aided embroidery refers to a hardware/software combination that allows for design sizing, positioning, and continuity in a way that would otherwise take hours or days for a person to do alone. The hardware is always an embroidery machine, and the software can either be loaded on the embroidery machine itself or onto a laptop connected to the machine. There are some examples of these computerized embroidery machines on Sirs Fabrics.

What are advantages of Computer Aided Learning?

Any time instruction - Human instructors have a limited capacity to be with you instructing you every hour of the day, a computer can be used to do exactly that. They will never get tired of repeating the same thing over and over through the use of video playback.

Automatic feedback - A computer can grade you immediately and let you know whether you got it right or wrong. It can always give you back good feedback. Some teachers may not always do that.

Enhanced help - A computer can utilize vast resources to give you help that a single teacher cannot.

Computer Examples - Computers can provide in depth, interactive simulations and examples that aids the learning in comprehending challenging topics. By using the software they can actively engage themselves and develop an understanding that would be difficult with static pictures.

What is the significance of Environmental Engineering?

IT is very useful branch of engineering.Due to this many new equipments are discovered. it increases the development of society as well as mankind. Many natural disasters could be known in advance. Technological development of society is root cause of calling developed society. By adding one more branch in technology adds one more mile stone in infra structure.

Why can't extrinsic semiconductors be fabricated from bivalent and hexavalent elements?

My thinking is ... If intrinsinc semicoductor is doped with Hexavalent Impurity, then energy level of outermost orbit of hexavalent atom, will fall below than that of pentavalent atom, so more amout of energy will be required to move this newly generated electron to move from fermi level to conduction band of semicondoctor. And vice versa for Bavalent.

How do you convert dwg autocad to pdf?

First of all, if you have AutoCAD viewers, no matter if it is a Full version of AutoCAD, an LT AutoCAD or even if it is an AutoCAD DWGTrueView, you can use a PDF virtual printer to get PDF directly from AutoCAD.

For AutoCAD users

DWG to PDF.pc3:

There is a default DWG to PDF.pc3 listed in AutoCAD printers, use this PC3 file to get PDF files.

Virtual PDF printer:

If you have a virtual printer, you can now directly print to PDF with it.

For non-AutoCAD users

If you still need to view drawings before getting the PDF, you need to find some applications which can view and let you convert to PDF.

Autodesk DWGTrueView and other viewers:

Get a free download of Autodesk DWGTrueView and print the drawing into DWG with some virtual printer in DWGTrueView.

Other viewers which can view and print or convert CAD drawings into PDF:

Search online and you will find there are lots of applications which are capable to do the both. See the related links below that I recommend.

AIGraph CAD Viewer:

Supports batch converting DWF/DXF and Dgn files to PDF.

DWG to PDF Converter:

DWG to PDF Converters should be able to batch convert DWG/DXF/DWF drawings for most of them are shareware and you need to pay to get the conversion or service. Such converters should be capable to:Batch convert DWG/DXF/DWFConvert all the drawings in a list into a single PDF
