CMOS switches are one of the main components of today's analog circuits. Among the many types of non-idealities that can affect the performance of the switch, its leakage current is of utmost importance. In order to reduce the leakage current or equally increase the OFF resistance of any switch, a novel technique is presented in this paper. The proposed technique employs the body effect to incr...
a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...
Purpose: To study the benefits of Directional Bremsstrahlung Splitting (DBS) dose variance reduction technique in BEAMnrc Monte Carlo (MC) code for Oncor® linac at 6MV and 18MV energies. Materials and Method: A MC model of Oncor® linac was built using BEAMnrc MC Code and verified by the measured data for 6MV and 18MV energies of various field sizes. Then Oncor® machine was modele...
iii ACKNOWLEDGEMENTS I would like to thank my advisor, Frank Durso, for his guidance, teaching, and encouragement throughout my graduate career. I would also like to thank my committee members, knowledge and advice through this dissertation. Lastly, I would like to thank my parents, my brother, my girlfriend, and my dog for supporting me and bearing with me through this dissertation.
Platinum-cerium oxide hybrid nanocatalysts (CeO(2)-Pt) were for the first time designed as bionanolabels for highly efficient electrochemical immunosensing of low-abundance proteins coupling nanocatalyst-based redox cycling with in situ signal amplification strategy.
Objective. To provide guidelines for enhancing the patient accrual process in clinical trials using communitybased Web-based Information Technology (WebIT). Background and Significance. Previous ITadministered education studies have been conducted in controlled environments: the computers are usually 1) supplied to the patients, 2) in an setting where a research facilitator can assist patients ...
