Investigation of a Radiofrequency Plasma Generator for Multi-Second Pulse Operation

A Modified Phase-Shifted Pulse Width Modulation to Extend Linear Operation of Hybrid Modular Multi-level Converter

Recently, hybrid modular multi-level converters, which are configured as full and half bridge sub-modules, are developed and utilized in the wide area of applications. Compared to its non-hybrid counterpart, these converters have several advantages such as the ability to nullify the DC side fault current and controlling AC side reactive power during the faults. This paper proposes a modified ph...

Investigation of Fuel Cell System Performance and Operation: A Fuel Cell as a Practical Distributed Generator

P2-8 Baseband Controlled Multi-Modulation Pulse Generator

This paper introduces a simple yet effective circuit topology to directly generate and modulate UWB pulses using baseband signals. The same circuit can be used to achieve Pulse Position Modulation (PPM), Pulse Amplitude Modulation (PAM), ON-OFF Keying (OOK) and Phase Shift Keying (PSK) by making changes in the baseband data. The method does not require the use of potentially expensive component...

the impact of training on second language writing assessment: a case of raters’ biasedness

چکیده هدف اول این تحقیق بررسی تأثیر آموزش مصحح بر آموزش گیرندگان براساس پایایی نمره های آنها در پنج بخش شامل محتوا ، سازمان ، لغت ، زبان و مکانیک بود. هدف دوم این بود که بدانیم آیا تفاوتهای بین آموزشی گیرندگان زن و مرد در پایایی نمرات آنها وجود دارد. برای بررسی این موارد ، ما 90 دانشجو در سطح میانه (متوسط) که از طریق تست تعیین سطح شده بودند انتخاب شدند. بعد از آنها خواستیم که درباره دو موضوع ا...

The GnRH Pulse Generator

The pulsatile secretion of hormones is an efficient way of coding a large variety of chemical messages. The GnRH pulse pattern determines which gonadotropin is released when and at what concentration, prescribing a detailed set of instructions to the gonads that produce changes in the steroid hormone milieu. Although GnRH neurons possess some inherent rhythmicity, they are diffusely situated wi...
