A new absorption spectrometer operating in the submillimeter wave region has been designed. The apparatus combines the previously reported1 fast scan submillimeter wave spectroscopic technique (FASSST) and a pulsed

In rapid-scan EPR the magnetic field or frequency is repeatedly scanned through the spectrum at rates that are much faster than in conventional continuous wave EPR. The signal is directly-detected with a mixer at the source frequency. Rapid-scan EPR is particularly advantageous when the scan rate through resonance is fast relative to electron spin relaxation rates. In such scans, there may be o...

در سالهای اخیر بسیاری از سازمانهای ایرانی اقدام به پیاده سازی سیستمهای برنامه ریزی منابع سازمان(erp) کرده اند. این سیستمها با تسهیل در طراحی سیستم به موقع و یکپارچه تولید و جواب مشتری، انقلابی در محاسبات سازمانی بوجود آورده اند. در حالیکه بعضی از شرکتها با استفاده از erp به کارایی قابل ملاحظه ای دست یافته اند، بعضی دیگر از شکست در اجرا،افزایش بودجه و عملکرد نامناسب شکایت می کنند. این پایان نامه...

Chalcogenide glasses such as arseic sulfide(As2 S3 ) have attracted attention for applications such as all-optical switching in high speed communication. This is due to their high non-linear refractive-index. Z-scan and the Degenerate four wave mixing (DFWM) techniques can be used to measure the non-linear refractive index n 2 and the two photon absorption coefficient β . A simaltanous closed-a...

The analysis of chessboard pebbling by Andrew Odlyzko is strengthened and generalized, rst to higher dimension and then to arbitrary posets. 1 The pebbling game The pebbling game of Kontsevich is played on the grid points of the rst quadrant. One starts with a single pebble on the origin and a move consists of replacing any pebble with two pebbles, one above and one to the right of the vanishin...

We report the development and initial implementation of what we believe to be a new rapid- spatial-scan millimeter-wave interferometer for plasma density measurements. The fast scan is effected by electronic frequency sweeping of a wideband (180-280 GHz) backward-wave oscillator whose output is focused onto a fixed blazed diffraction grating. The system, which augments the rotating-grating scan...

We report the development and initial implementation of a new rapidspatial-scan millimetre-wave interferometer for plasma density measurements. The fast scan is effected by electronic frequency sweeping of a wide-band (180-280GHz) backward-wave oscillator (BWO) whose output is focussed onto a fixed blazed diffraction grating. The system, which augments the rotating-grating scanned multi-view H-...
