Why do East Asian requests for help always come with "urgent!!" on them?
I've seen plenty of requests that would have gotten answers but for
the demanding tone.

Hi Ben,

Two things wrong with this:
1) He's in Ankara (West, not East);
B) We get the same the same urgent requests from American students in
Florida (and all points north and west of there too).

The end of term is coming up.

I) I guess if I'm going to generalize I'd better pay more attention.

Two) I still think there's a cultural/language issue going on. I get
questions all the time from people about projects on my web page.
Almost all of the ones from people with Chinese/Indian sounding
names (hard to tell where they're from if they don't volunteer it and
they're using Yahoo mail!) are demanding. Here's the first example
in my inbox, although this one is relatively tame:

] i'm very interesting about this project because i want to use this simple card
] for a simple interface with the hardware outside for example for a simple
] input/output. i want to ask about the schematic of this project. Can you help
] me for this. i wait your answer as soon as possible.

In contrast, American students seem to just cut and paste requirements
from the handout. ;-)

I once worked for Oki Semiconductor and received a manual that had
been translated from Japanese to "English" by a Japanese Engineer.
One sentence translated as: "The user functions are functions that
are used by the user." I wondered what had gotten lost in that
translation.

Hi Ben,

My professional page got me inquiries from a private investigation of
the TWA flight 800 crash. But I got something in return, a graphic
chart of all the flight control settings from take-off until the
lights went out. The questions I got from the lawyer went deeper than
any student's final project.

Attend class, stay awake, take notes, study, pass simple exam question.

Getting the answer here or from Google is called plagiarism. You get an
'F' if the instructor finds out.

Hello,
I can not handle a problem which is about AGC. Please help me about
that. The conditions are;
It is required to design and implement an AGC circuit
with the following specifcations:
1. Amplitude of the input voltage may vary between 10 mVpp and 50 mVpp.

2. Amplitude of the output voltage should be in the range 0.9 Vpp
and1.1 V
pp for the input signals with amplitudes stated above.

3. Output impedance of the ampli¯er should be smaller than 2 k*.

4. The circuit should be able to amplify the signals having frequencies
between 500 Hz and 10000 Hz.

The amplifer designed should be a single transistor amplifer in the
common-emitter form for BJT amplifers or common-source form for the
FET amplifers. However, it can be used extra transistors for making the
amplifer an adjustable gain amplifer.

And the AGC should be composed of 2 parts adjustable gain part and
feedback part.

Please help me urgently to design this problem. Thanks...

It's a technology race, and the instructors are well ahead.

Dissertations can now be scanned by Google-type software that looks for
copying. Whatever literature resources the student could have used, the
department has access to the same and more.

A friend told of a recent example of a final year dissertation on 2.4GHz
LNA design. The software easily found the un-referenced Agilent
Application Note that the student had copied. They had already been
warned...

Dear Ian:
The worst case that I encountered was the finding of a direct copy of my
own work in a student's thesis! I was not amused!

On the other hand, I recently was faculty advisor on a thesis of
exceptional quality and originality. The student had performed some
valuable and original work with nano-technology. The student's care in
crediting each and every idea that was used and every person who helped
(including skilled technicians) was a model of what should be done. The
best students know, and acknowledge, their antecedents, mentors and then
delineate what they have done that is new.

I offer the above as an example that not all is lost.

Warm regards, Mac N8TT

Had the same happen to me: read an article in a German radio magazine
that was written exactly as I would have... no, dammit, it was written
exactly as I already HAD, in a different magazine!

Oh, indeed it isn't. The friend who told me about the copy-detection
software had spent 20 years of his life as a rock musician, but is now
headed for a First Class honours degree in RF Engineering. Needless to
say, he's an active ham.

Glad to hear there is still integrity in some circles.
