  1. IPS is going to file this as a bug, however, they are claiming that Jim might be the only one with this problem. So I'd like to get more feedback on this from the rest of the members. Is anyone else having problems jumping to the latest unread post similar to what Jim is experiencing? If so, what browser and version are you using?

    Using Firefox 3.0.11 on Windows XP, "View New Content" gives me the list of threads and clicking on one takes me to the very last post in that thread, rather than the first post I haven't read.

    Hello LAVAs!

    I want to make my ranking system using 15 education levels like:

    nursery child

    pupil

    ...

    bachelor

    master

    professor

    Could anybody give me a web link to the full list of all available levels of education/graduation or write here in this topic what levels there are? I can't find such list by google.

    Thank you, Eugen

    I think you're going to find it difficult to compile a definitive list because there are different educational structures, even within the same country. If it helps here's what happened to me: in the UK from 1969 onwards:-

    Primary school: 2 years, aged 5 - 6

    Infants school: 4 years, aged 7 - 11

    Secondary school: 5 years, aged 11 - 16, 'O' level and CSE exams (Now replaced by GCSEs)

    6th Form college: 2 years, aged 16 - 18, 'A' level exams

    University: 3 years, aged 18 - 21, Bachelor of Science

    Beyond what I did, were Masters and Doctorate (Phd)

    hello again

    in the first message on this topic there are a atached file where i send the VI whith a pecture of what i wnat and what i get.

    please lokk at the first message and you will be understand.

    of any other question im here.but quiqly the work sould be finishedtomorow please. thank you.

    As I and others have already said, there isn't enough information in your original post to be able to solve your problem. Good luck.

    Kevin

    yes kivin

    if you want wich commandes i sent? i send the SCPI commandes and all commandes work, but the last commandes is (TRAC:READ?) for reading the values and i had a signal but it is not correct do understand me?

    else i don't now what you want exactely for explining?

    Yes I understand that the plot you get isn't what you were expecting, but it would help if we could see a screen grab of the plot you get, and also to see the string data returned from the instrument, because without seeing the scale of your measurements (i.e. how many amps you are reading) it's hard to tell what is happening.

    but i said e(t)=5sin(100t);

    so Amplitide=5v

    frequency wt=100 and f=2*3.14*w

    but my programme will acquit from any e(t); and it's good (look my attached file in th firste msg) but my probleme is with the buffer when i apply "read"

    and my friends this work should be finished this friday, so help me please :(

    Sorry zhipppo16, but you're not giving us enough information - your original attatchments are missing too much. You need to re-read the replies and get the answers we've asked for, if you want help. Also putting comments on the block diagram explaining the reason for each of the commmands you've sent to the instrument would be a good idea.

    hello;

    yes Kevin i want to visualise a current.

    1* i will apply e(t)=5sin(100t)

    2* the voltage wille be sin v(t)=x*e(t)

    3*the current i(t)=v(t)/R

    so the currant have a same form of voltage ok?

    and i conect a Keithley 6487 with a circuit serialy not parallèle, so i can make this?

    and thank you

    I'll start by repeating my request that you post a tidied version of the block diagram, then I have more questions.

    What frequency and amplitude is your input signal, and what sample rate are you measuring at? (I'm hoping you know about the Nyquist frequency). I'm looking for you to reply with numeric values rather than equations.

    i am waiting a help please members he doesn't undertand

    I don't have an answer, but I do have a request and a question:-

    My request is that you tidy up the block diagram so that you have got all the wires going from left to right and not going backwards. You also need to make sure your wires don't disappear under the sides of the sequence structure. I request this so that we can understand your block diagram.

    My question is... do you have a drawing of how you have the instrument connected to the resistor and diode, and what voltage sine wave you are applying? I ask this because the Keithly 6487 is an ammeter for measuring current, yet you seem to be trying to measure voltage with it, so I think I must be not understanding how you have it connected.

    Long time ago I was thinking the Secrets are in the US or in Russia; later I realized are not secrets there, governments didn't come with any secret yet.

    People were going in Tibet, India… looking for Secrets wasting theirs lives in ashrams, monasteries…

    I was 2 months in Germany at the biggest ashram in Europe and aren't secrets there.

    Looking for Secrets in books is not a solution…

    Perhaps there aren't any Secrets to find?
