Information Security (IS) specialists’ training for all sectors of trade, industry and government has never been more important as intellectual property and other sensitive or business-critical information becomes the life-blood of many companies today. Analysis of the experience collected within training of IS specialists at the Moscow Engineering Physics Institute (State University) (the MEPh...
ISO 50001: 2011 provides an integrated and systematic framework to plan, implement, operate, certify, and maintain energy management systems (EMSs). Evaluation of organizations in relation to meeting the standard requirements is performed by an auditing qualitative approach. In this research, a quantitative approach has been proposed and implemented to assess organizations and rank them based o...
چکیده هدف از این پژوهش که با روش توصیفی از نوع پیمایشی و از شاخه تحقیقات میدانی انجام گرفته است؛ ارزیابی نظام آموزش کارکنان دانشگاه شاهد بر اساس استاندارد بین المللی ایزو 10015 و با تاکید بر فرایندهای عمومی نظام آموزشی کارکنان می باشد. جامعه آماری تحقیق کلیه کارکنان دانشگاه شاهد در سال 1392 را شامل شده و از بین آنها تعداد 300 نفر به عنوان نمونه آماری با روش تصادفی طبقه بندی شده انتخاب شدند. ا...
abstract weirs are the most common structures for discharge measurement in engineering research. streamline curvature, non hydrostatic pressure distribution on weir and nappe adherence to the weir lead to differences between calculated and measured discharges. thus discharge coefficient, which is the ratio of real and theoretic discharges, is usually less than unity. in circular weirs the press...
We have used the Long Wavelength Spectrometer (LWS) on board ISO to observe the fine structure lines of atomic silicon at 68.5 and 129.7 microns towards the Orion KleinmannLow nebula. Our data show evidence for the detection of the J=2-1 transition at 68.5μm with a signal-to-noise ratio of 5. We consider the formation of the observed emission line and conclude that it is likely to form in the C...
The PIS A-method, Proximal Isovelocity Surface Area, is a method for quantifying regurgitant flow through the mitral valve. The volumetric flow is calculated as the velocity at the center line times the iso-vehcity area. Unfortunately, this method is correct only for a non-viscous fluid flowing towards an orifice with zero radius. In order to study effects from a viscous fluid as well as influe...
