the purpose of this study was to examine the english language needs of medical students at tehran university of medical sciences . analysis of the needs took place for three groups: 320 undergraduate students, 30 postgraduate students and 20 university instructors. a triangulation approach to collect data was used in which a combination of the quantitative (using the questionnaires) and qualita...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
We present a novel design for quadrature phase detection utilizing two-mode optical waveguides for optical interferometric systems. A pair of interferometric signals having quadrature optical phase information can be obtained from the near-field and far-field patterns of a two-mode waveguide output. The operational principle is based on a pi/2 differential phase shift between two modal beams oc...
Alibeik, Maryam. MSECE, Purdue University, August 2014. Different Configurations of Microgrids and Power Converters. Major Professor: Dr. Euzeli dos Santos Jr. This thesis proposes a two-phase microgrid system with voltages in quadrature. The two-phase microgrid system presents the following advantages: 1) constant power through the power line at balanced condition; 2) two voltages available by...
This study focuses on building a framework which calculates the weights of FAHP (Fuzzy Analytical Hierarchical Process) method , then integrates the analysis tools such as FQFD (Fuzzy Quality Function Development) and FFMEA (Fuzzy Failure Mode and Effects Analysis) into the framework to construct a two-phase product specifications evaluation process. Therefore, this study builds a framework and...
