Safety assurance is of paramount importance in the air transportation system. In this paper, we analyze historical passenger airline accidents that happened from 1982 to 2006 as reported National Transportation Board (NTSB) aviation accident database. A four-step procedure formulated construct a Bayesian network capture causal relationships embedded sequences these accidents. First all, with re...

The article presents the results of study influence monitoring and diagnostic means on values reliability functional safety indicators fault-tolerant information transmission systems. was carried out by modeling several variants a system. As method, an improved state transition diagram with automated construction graph states transitions is used. On basis obtained results, recommendations for s...

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...

— Various model parameter calculation equations of RF CMOS inductors are compared. The calculation equations are using as variables either Y, Z-parameters or S-parameters. Results are based on on-wafer RF S-parameter measurements of a 3.75 turn spiral inductor fabricated in AMIS 0.7 μm CMOS DM1P n-well technology. Results obtained with calculation equations for a differentially driven inductor ...

Most accidents happens because of lack of Visibility and not Driver’s reaction on time whenan accident occurs. Increasing required Time for driver’s reaction caused to decreasingaccidents on roadways .intelligent vehicle networks brings enough time for reaction by sendingalert and alternate messages to vehicles on roadway. Main propose in this paper is aroundmodulation on Reception interval Saf...

OBJECTIVES To determine the prevalence rate of post traumatic stress disorder (PTSD) and associated risk factors among motor vehicle accident (MVA) survivors attending the orthopaedic and trauma clinic at Kenyatta National Hospital, Nairobi. DESIGN A cross-sectional study. SETTING Kenyatta National Hospital, Nairobi. SUBJECTS One hundred and ninety seven adult males and sixty seven female...

PROBLEM There is concern in the aviation community that pilot schedules can lead to fatigue and increased chance of an aviation accident. Yet despite this concern, there is little empirical analysis showing the relationship between pilot schedules and commercial aviation accidents. This study attempts to demonstrate an empirical relationship between pilot schedules and aviation accidents. MET...

Posttraumatic stress disorder (PTSD) is possibly an overlooked diagnosis of victims suffering from traffic accidents sustaining serious to severe injuries. This paper investigates the incidence of PTSD after traffic accidents in Germany. Data from an accident research unit were analyzed in regard to collision details, and preclinical and clinical data. Preclinical data included details on crash...
