A vehicle for a complete engineering and scientists practical formation is presented. It is made possible by the use of virtual instrumentation, not in the sense of a simulation tool, but as the remote access to facilities located in related research laboratories. Internet World Wide Web provides a best way to materialize this remote access, reducing the requirements in the educational laborato...
Each of the four fractional betatron tunes of RHIC (two planes, two rings) is measured with a transverse beam kicker and dedicated beam position monitor (BPM). A 15kV pulse is generated by a fast FET switch, passed through a stripline kicker, attenuated, and returned to the instrumentation control room (ICR) for monitoring. When pulsed at 3kV, the four-meter long kicker gives a gold beam at inj...
مدل سازی مناسب بار برای تحلیل پایداری سیستم قدرت امری ضروری می باشد. در این پروژه سعی شده است با استفاده از روش اندازه گیری، ضمن معرفی و استفاده از دستگاهای اندازه گیری ثبات(دیتا لاگر) و پاورآنالایزر به مدل سازی بار چند تعرفه مختلف در شبکه توزیع برق کرمان پرداخته و با استفاده از پالایش اطلاعات خروجی این وسایل اندازه گیری یک مدل بار مرکب مناسب برای بارها در نظر گرفته شده استخراج نمود و پس از دست...
industrial organizations are complex systems` where the interactions among the various functions such as sales, distribution, manufacturing, materials, finance, human resources and maintenance have to be man-aged towards a common purpose of delivering the customers satisfaction. however, since most of these or-ganizations have a `functional structure`, each function or department works towards ...
measurement of the joint angles is used to assess the joint position sense (jps). the aim of this study was to introduce a simple, fast, less expensive and objective method of measurement for jps. in the current research, the accuracy and reliability of a system, consist of digital photography, nonreflective markers and manual analysis were evaluated. for this purpose, digital photos were taken...
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 ...
Background and Aims: Estimating the canal length is essential for reaching to a proper endodontic treatment. Any error and miscalculation in estimation of the working length, especially in curved canals, can result in complication during and after root canal therapy. The introduction of digital radiography has enabled us to measure curved canal length. The purpose of this study was to evaluat...
Background & Objective: The present study aimed to identify the barriers in the current system of organizational performance measurement and determine the educational challenges within the framework of Stufflebeam and Coryn (2014) meta-evaluation model in 14 educational offices in Zanjan province, Iran. Materials and Methods: This exploratory study was performed using a qualitative approach an...
