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 To Learn CAD drafting technique easily?

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.

What is constant variables?

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.

Can polygons be 3D?

No. That would make them a prism.
