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 To Learn CAD drafting technique easily?
Are you willing to learn the special CAD drafting techniques? There are several options being available in the market that help you to learn this computer aided drafting without any difficulty. You can check out the options that have been enlisted below:
1. It would be best if you enroll yourself in the degree program of applied sciences in CADD. This will help you to learn every technique that is required to learn about computer aided drafting.
2. If you want to learn more your option will be to pursue a BA degree in computer aided drafting. Here you will be able to learn various facades of CAD like mechanical ad architectural drafting, 3D rendering and modeling. Otherwise you can also take up special AutoCAD certificate courses also.
3. You can also gather enough knowledge and keep yourself updated by studying several books on CAD. There are several websites that also help you to gather vital information and current news on this technology. All these help you to horn your skills.
4. You can also get hold of e book or special articles of experts that can throw much light on the nitty-gritty of this technology. Current news on CAD and its application son various fields like engineering, architecture will be beneficial for you.
What is the operating temperature for TTL?
The operating temperature for standard commerdcial TTL (74 series) 0 to 70 degrees Celsius. Military grade between -40 and 125 degrees. Some commercial 74 series used for industrial and automotice applications between -15 and 85 degrees C. In the real world standard commercial TTL often works quite happily under mil spec conditions. I know because I have tried it!
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
Convert separate drawings into PDF one by one
Convert one PDF per layout in the drawingXREF files and ShX fonts supportivePDF page sizeColor modeLine weight
You can convert DWG to PDF in just three steps. Follow the guide below the source: How to convert DWG to PDF easily.
Which CAM or CAD software is mostly used for sheet metal works?
There are many softwares in the market today for Sheet metal work. I have experience with a few of them. But till date the best sheet metal softwares I have ever used considering factors like user friendliness, cost effectiveness, etc. MetaCAM by Metamation is the best one.
You can find more information about MetaCAM sheet metal software in Australia and New Zealand by visiting www.nccs.com.au
In the computer aided machine drawing how to draw the projection in 3d drafting?
by using cad cam software
What are some examples of quantitative data?
Quantitative data is data that measures quantity, as opposed to qualitative data which describes quality. Some examples of quantitative data pertaining to weather would be: measurements of precipitation, records of number of days per month without precipitation, percentage of the chance of precipitation, records of daily high temperatures.
Does MSC Adams Student Edition contain Adams-Car?
No. It only includes Adams/View which lets you create and simulate simple mechanisms.
Variables are items, which change their values during the execution of a program.
Constants do not change the value during the execution of a program.
Give an example of quantitative data?
Quantitative data deals with numbers. It is data that can be measured. An example of this is: 51% of the world's population is female.
No. That would make them a prism.
* * * * *
No. A polygon is a 2-dimensional object ad so cannot be 3-d.
Also, there is no need for the shape to become a prism, as suggested by the previous answer.
What is the advantages of automated car parking system using microcontroller?
you dont need round the clock attendants or valets
you tend to need more expensive labor to fix the machines tho
these can be part timers since we have cell phones now
possibly cheaper than live parking attendants but response time is a LOT slower
Where can you find a CAD drawing of a Supra?
the TAMIYA 1:24 Supra comes with orthographic drawings of the Supra-- (left, top, front, back views)... that's the most accurate drawing out there that I've seen, but can't help you with the CAD drawings.
Can the contrast agents used during computed tomography scans be dangerous?
Contrast agents are often used in CT exams and the use of these agents should be discussed with the medical professional prior to the procedure. Patients should be asked to sign a consent form concerning the administration of contrast.
Good luck !
-- Those frequencies are being auctioned now, raking in $erious buck$ for the govt. Like in the billion$ !
-- Once a license is granted, there is a time limit within which you must use it, i.e. put something
up on the air on the assigned frequency, otherwise the license lapses and you no longer own
the frequency.
Television sets do not need to be connected to isolation transformers for normal operation. However, most modern sets do not have power transformers, which means they run directly off of the line. In that case, you do need an isolation transformer to protect yourself from electrocution during repair.
