FlexRay, as a communication protocol for automotive control systems, is developed to fulfill the increasing demand on the electronic control units for implementing systems with higher safety and more comfort. In this work, we study the impact of radiation-induced soft errors on FlexRay-based steer-by-wire system. We injected the soft errors into general purpose register set of FlexRay nodes to ...

Optimally minimizing delay times at signalized intersections can significantly improve both traffic flow and safety. However, most traffic flow optimizing tools do not measure the effect on safety. This study uses nonlinear programming (NLP) algorithms to optimally minimize delay times and employs both Safety performance functions (SPFs) and empirical Bayes (EB) before-after methodology to meas...

With more minimally invasive surgery, the C-arm has become a regular resident in the OR. Surgeons rely on imaging during cases to guide implant placement and other critical aspects of surgery. How much radiation are OR teams being exposed to, and what safety measures should they be taking? Safety pointers were offered by 2 radiology managers: Jeff Palmucci, CRA, director of radiology services a...

This paper describes a safety assessment study of near-infrared sources used in an optical brain-computer interface (BCI). The measurement elements of an optical BCI consist of sets of optical sources and detectors. Our current system utilises sources which comprise of dual wavelength light emitting diodes (LED) at 760nm and 880nm. An optical analysis demonstrated that NIR radiation is a neglig...

background: radiation-induced lung injury is a refractory side effect in lung cancer radiotherapy, the mechanism still remains unclear, hence an appropriate animal mode may become useful to investigate it. materials and methods: 50 female wistar rats were randomly divided into 5 groups, average 10 rats/cage: a. control group b. 3gy×10f c. 6gy×5f d. 12.5gy×1f e.15.3gy×1f. by different doses of r...

background: it is believed that improved safety culture/climate is a fundamental element to accident prevention. therefore, development a scale to assess safety climate is a step towards accident control. the purpose of this study was to construct a persian safety climate questionnaire. methods: the study took place in tehran and esfahan oil refineries in iran in 2010. an initial questionnaire ...

The purpose of this work is to improve the Russian Radiation Safety Standards (NRB) in terms interpretation meaning “the main limit annual effective dose” and use concept “emergency”. In [1], proposals were submitted discuss changing new versions NRB Main Health Rules for (OSPORB) dose man-caused occupational exposure” health physics regulation radionuclide contents solid materials free or limi...

Recent articles in US newspapers(1-4) have increased the awareness of the public to the potential dangers of incorrect delivery of medical radiation. In response, many of the leading organizations representing users of medical radiation have joined to identify and address the common issues that could substantially improve the safety and quality of the use of medical radiation. I have invited Dr...
