Why electronics are bad for you?
Kids should not bring in electronics to school unless they are instructed to do so by their teacher or another member of staff, for a number of reasons.
1. Primarily, personal property can be easily lost or stolen.
2. Should that happen, the student would be very disappointed and the school would not be able to help.
3. Students bring personal property on school premises at their own risk, and should be aware that their items have the potential to be lost or stolen.
4. Second, electronic devices disrupt the learning process if they are used within school hours.
5. For these reasons, electronic devices should not be brought to school, or if necessary, should be off and stowed away until after school hours.
6. They are the primary carrier of viruses and malware.
7. They don't always care about security.
8. They'll even use your email as a keychain for keeping track of their email passwords.
9. They don't always read everything that's displayed on the screen.
10. Unless regular breaks are taken and careful attention is paid to one's posture, RSI can result from prolonged use of the computer.
11. Kids are not burning off any of these calories while they are plopped in front of the television.
12. Due to the ease of access to the internet kids now expect immediate responses and rely on the internet to give them all of the answers.
13. Computer addiction can have a variety of negative effects on a person. The most immediate are social. The user withdraws from friends and family as he spends more and more time on the computer.
14. Relationships begin to wither as the user stops attending social gatherings, skips meetings with friends and avoids family members to get more computer time.
15. Users may become irritable when away from the computer, causing further social harm.
16. Computers and other related technologies have become an enormous part of our daily lives.
17. Loud music damages their hearing plus interferes with their studies, allows them a means of cheating, causes disruptions in class, and many other ways.
18. They are unhealthy and some violent.
19. Kids are saying rude things to their parents and there it was thought back to that game they were playing.
20. The whole point of going to school is to learn, not listen to music while texting your friend across the room.
21. It is easy and it does not take a lot of thinking because when you are chatting or texting with someone most of the kids use short term words to make it faster to talk.
22. If say, an armed man enters the school, obviously phone calls to parents would be left right and center, and if so calls are being made at the same time, the network system thing would just get screwed up because it's so busy!
23. If that happens, parents can't do anything if they're at work, that's why we have police.
24. IT in general - that's computers, servers and so forth - were calculated to be causing about 2% of global carbon dioxide emissions.
What is the name of a robot used to build cars?
There are several different manufacturers of industrial robots, and each manufacturer uses their own naming/numbering system to distinguish different product lines.
What is groupwise electronic configuration?
Elements in the same vertical column or group have similar valence shell electronic configurations,the same number of electrons in the outer orbitals, and similar properties.
How compiler differ form interpreter?
because the compiler convert whole of the sentence once into the machine langauge but the interpreter convert one by one
Hetrodyning means to mix the incoming signal, with a locally produced signal, to produce a third.
When two frequencies are mixed, you get four. There are the two original frequencies, the sum of the two frequencies and the difference of the two frequencies.
By using a filter you can separate out one of the mixes.
Most modern radios are Superhetrodyne types.
Developed to stop 'howl round' feedback, when amplifying a radio signal.
To get better selection you need to amplify the incoming signal. When you do this, the receiver will then detect this amplified signal and reinforce it, causing unwanted feedback, unless extreme measures of screening are involved.
A superhet, mixes the incoming signal with a local oscillator. This is then passed to a filter which selects one of the mixes. This intermediate frequency can now be amplified without the front end 'seeing it'. The IF remains at a constant frequency and can be amplified many times, before detection to remove the carrier. Making for a very sensitive, selective and stable radio receiver. (AM radios typically have an IF of 470Khz)
Tuning is achieved by varying the local oscillator, a different incoming signal will then match with the filtered signal, after mixing.
Dual gang, variable capacitors, are used for tuning. One capacitor selects broadly from the aerial, the second controls the frequency of the local oscillator.
What does it mean when wall socket for ceiling light sizzles and the light dims?
It means you should call a licensed electrician to fix it immediately.
If you didn't already know that, you personally have no business around electricity.
While the above answer is true to an extent, there is a better answer.
The sizzling in a wall socket and lights dimming means you have a short in the circuit, usually in the switch itself.
Active 3D glasses are far better than passive glasses when used with an active 3D television. Similarly, passive 3D glasses work well with passive televisions.
Active glasses have been criticized for their weight in the past. Later glasses are lighter than many passive glasses, have a battery life of over one hundred hours and are proving to be exceptionally reliable.
Audio Units virtual synthesizers are available in commercial (paid) titles and a few free ones. I assume you have tried to work with Ultrabeat, the beat creation plug-in that comes with Logic Pro 8 and 9. If this one doesn't work for you, you should try MOTU's BPM or Native Instruments' Battery.
Sure. I bought one a few years ago for wii-fit, and i think that it works pretty well :) there are a lot of things to do on a wii, including A TON of fun games. I personally like it alot better then the kinnect for xbox 360. Plus, the wii has gone down in price by alot.
What is the percentage of getting a virus of any kind on an Apple computer or laptop?
There are no viruses that affect Mac OS X so the chances of getting a virus is zero. It is possible, although highly unlikely, that an unwary user could download and install some malware but the number of Mac users who have ever done that is probably less than one per cent.
What is sequence detector in digital electronics?
Sequence detection is the act of recognizing a predefined series of inputs. In our case, we are
looking for very simple things very slowly. We are looking for a series of ones and zeros similar to
1011. The overwhelming beauty of programmable logic is its ability to work with DSP (digital
signal processing). The capability of processing a great deal of information quickly can not be
overemphasized. Suppose you were working at the VLA in Socorro and you wanted to scan
thousands of bits of digital information looking for a series of bits that represents an RF signal
from a distant galaxy. Or, suppose you wanted to scan a digital image of a human lung looking for
a digital signature that could represent a cancerous cell. These are very broad interpretations but
I believe you can see where the benefits come in with being able to recognize a specific
sequence.
A sequence detector is a sequential circuit which is basically a circuit that can store information
between operations. There are two main models for sequential circuits: Mealy and Moore model.
A Mealy model circuit the output depends on the inputs and the state of the system, in a Moore
model, the output of the system only depends on its state. Please review your class notes on
state diagrams for sequential circuits.
Design a Sequence Detector
For this lab we’ll need to create a sequence detector with the following characteristics:
• Serial input X
• The sequence to be detected is 10010.
• Five bits wide output Z with value 00000 when no sequence is detected, 00001 when the
first bit of the sequence is detected, 00010 for the second bit, 00100 for the third bit,
01000 for the fourth and 10000 when the whole sequence is detected.
• If input Y is one, the system is reset to output 00000.
This is a sequential circuit; therefore we will need a clock. Since the XCR board we are working
with does not include a clock, we will use the slowest clock we have: your finger!
