Background & Objectives: Quality and effectiveness of safety systems are critical factors in achieving their goals. This study was aimed to represent a method for performance evaluation of safety systems by proactive indicators using different updated models in the field of safety which will be tested in a selected industry. Methods: This study is a cross-sectional study. Proacti...
در این پروژه سعی بر ارائه طرحی از یک حذف کننده رادار mti بوده است. در طی طراحی، روشهای گوناگونی اعم از روش استفاده از فرکانس تکرار پالس سرگردان (staggered prf) ، خاصیت جهش فرکانسی (frequency agility) ، بانکهای فیلتر گوناگون، بکارگیری پنجره های زمانی مختلف (kaiser, hanning, hamming, blakman, bartlett, uniform) و روش چند فرکانس تکرار پالس توام (multi prf) شبیه سازی شده و نتایج...
growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
On each of three sessions, 5s viewed 20 presentations of an isolated accident (experimental group) or a benign (control group) motion picture scene. At the end of each session, 5s also saw the complete movie from which these scenes were taken. Skin conductance, self-reported distress, and, to a lesser extent, heart rate showed considerable carry-over of habituation from the accident scene viewe...
conclusions path analysis of occupational injuries based on the sem reveals that individual and organizational factors and their indicator variables are very influential on the severity of traumatic occupational injuries. so, these should be considered to reduce occupational accidents’ severity in large construction industries. materials and methods the present cross-sectional analytical study ...
In this thesis, the author concentrates on marine accident frequency models and on the analytical estimation of accident frequency in the Gulf of Finland. The Gulf of Finland is a sensitive sea area and a part of Baltic Sea. Automatic Identification System (AIS) data of 2008 is used in the calculations of ship-ship collision and grounding frequency. In addition, an estimate of collision frequen...
Objective: This paper makes a projection of the vehicle ownership rate to the year 2010 and to use this projection to predict road accident deaths in year 2010. The projection served as an indicator for the Malaysian government to achieve a 4 road accident deaths per 10,000 vehicles safety target in year 2010. Method: The study included the prediction of vehicle ownership and the analysis of pa...
Background: Millions of construction industry accidents occur in the world causing demages and injuries to workers and consequently economical losses every year. The aim of this study was to determine an estimator model for accidents among construction industry workers, in the years 2006 - 2011 for the first time, in Yazd city. Materials and Methods: In this descriptive study, ...
