ITES stands for Information Technology Enabled Services. Its full forms are available for download at the Full Form Directory.

mep is able to chare files between project disciplines...say strutural changes a piperack...electrical and piping will see in their DWG and change accordingly instead of having a separate model program where you have to take out cut paste ETC

working stress: in this a structure is designed by considering the stresses in its working condition..
Limit state: In this the structure is designed by considering the stresses at different limit states. there are two limit states. ultimate limit state (situation in which structure collapse) and servicability limit state (situation in which cracks etc appears.)

CAD can be put into 5 main categories which evolved like so....

1) Graphic Communication Enhancer (ie pen and paper replacement)

2) Part Modeller

3) Dimension Based Part Modeller

4) Feature based and dimension based part modeller

5) Building Information Modeller (BIM)

5 evolved from 4 but isn't really an improvement is more of an off shoot from 4 after it was created.

But 4 and 5 contain properties of each but are focused on different industries, mechanical and architectural respectivly.

Sectional views are used to shows the internal detail of an object. The drawing will show the interior part of an object as if it was cut in half or quartered. essentially a flat plane passed through a 3 dimentional object highlighting all the internal detail

A wireframe model is an edge or skeletal representation of a real-world 3D object using lines and curves. -Frank-

Proximity switches open or close an electrical circuit when they make contact with or come within a certain distance of an object. Proximity switches are most commonly used in manufacturing equipment, robotics, and security systems. There are four basic types of proximity switches: infrared, acoustic, capacitive, and inductive.

Infrared proximity switches work by sending out beams of invisible infrared light. A photodetector on the proximity switch detects any reflections of this light. These reflections allow infrared proximity switches to determine whether there is an object nearby. As proximity switches with just a light source and photodiode are susceptible to false readings due to background light, more complex switches modulate the transmitted light at a specific frequency and have receivers which only respond to that frequency. Even more complex proximity sensors are able to use the light reflected from an object to compute its distance from the sensor.

Acoustic proximity sensors are similar in principle to infrared models, but use sound instead of light. They use a transducer to transmit inaudible sound waves at various frequencies in a preset sequence, then measure the length of time the sound takes to hit a nearby object and return to a second transducer on the switch. Essentially, acoustic proximity sensors measure the time it takes for sound pulses to "echo" and use this measurement to calculate distance, just like sonar.

Capacitive proximity switches sense distance to objects by detecting changes in capacitance around it. A radio-frequency oscillator is connected to a metal plate. When the plate nears an object, the radio frequency changes, and the frequency detector sends a signal telling the switch to open or close. These proximity switches have the disadvantage of being more sensitive to objects that conduct electricity than to objects that do not.

Inductive proximity switches sense distance to objects by generating magnetic fields. They are similar in principle to metal detectors. A coil of wire is charged with electrical current, and an electronic circuit measures this current. If a metallic part gets close enough to the coil, the current will increase and the proximity switch will open or close accordingly. The chief disadvantage of inductive proximity switches is that they can only detect metallic objects.

Proximity switches are used in manufacturing processes -- for example, to measure the position of machine components. They are also used in security systems, in applications such as detecting the opening of a door, and in robotics, where they can monitor a robot or its components' nearness to objects and steer it accordingly

1 disadvantage is that it might not always be as accurate as you want it to be

IF you count the base five, if not 4. I would know because i made a cardboard one and then i found out it was 4 so i had to startover. It sucked.And i thought it was three!

AutoCAD does not support parabolas. You would need to download an AutoLISP routine or approximate the parabola with it's geometric equation and a spline. The downside to an AutoLISP routine is that you do not know how good it is and it might not play nice with other commands.

Lt in autocad stands for nothing realy,

The difference between LT and the full version of AutoCAD is that LT

does not include 3d functions and does not support Lisp.

You can call it :

* lite * low tech * learning and training( in sweden) * Less Trouble As far as I know LT doesn't mean anything.

Physical models are models you can touch

A monostable is a circuit that will respond to a stimuli only once and only for a period. Its usage can be many depends of applications

Direct data capture is the collection of data for a particular purpose (e.g. barcodes being read at a supermarket so that the product can be identified or account details being read directly from the chip embedded in the credit card.)

Indirect data capture is the collection of data as a by-product from data collected for another purpose (e.g. using data collected from reading barcodes at a supermarket till to work out the stock levels or using data collected from reading barcodes to see whether an item is selling well.)

To make a full subtractor, you need an XOR and a NAND gate.

The "limits" define the area of your "drawing board" (field). It is not neccessary to set them to form an inordinately large, or infinite field at the start of a drawing, as they can be altered later if needs be. It is neccessary to set them, however, as in certain circumstances the program uses zero as the default setting. If you blithely accept this setting you will have no field in which to produce your drawing.
