safety issues have always been put forward as one of the major problems and primary concerns in construction industries in many countries. this paper will focus on the impact of safety training on safety climate and its relevant factors in two sites of a construction firm. the health and safety executive (hse) guide to safety climate tool that had been validated in iran was used to determine th...

the previous studies show that a high percentage of traffic accidents take place in two-lane rural highways and most of which happen at horizontal curves. meanwhile the horizontal alignment is often subject to hard topographic conditions where because of economic aspects designers are forced to design horizontal curves at grades. vertical angle of longitudinal slope reduces the normal force of ...

by application of design spectra in seismic analyses, determination of design spectra for different site conditions, magnitudes, safety levels and damping ratios will improve the accuracy of seismic analysis results. the result of this research provides different design acceleration spectra based on iran earthquakes database for different conditions. for this purpose first a set of 146 records ...

introduction: global patient safety is the concern of all areas of the health care. in addition to the human suffering in those inflicted unsafe care and services, it has a heavy economic cost. due to the sensitive patient safety in the operation rooms, the present study aimed to assess patient safety in the operating rooms. methods: this was a descriptive cross-sectional study that was conduct...

Every year, more than 400 people are killed in over 1200 accidents at road-rail level crossings in the European Union. Together with tunnels and specific road black spots, level crossings (LC) have been identified as being a particular weak point in road infrastructure, seriously jeopardizing road safety. Safety at LC is a single part of a wider picture of transport safety within the whole tran...

Our critical computing systems are coded in low-level, typeunsafe languages such as C, and it is unlikely that they will be re-coded in a high-level, type-safe language such as Java. This invited talk discusses some approaches that show promise in achieving type safety for legacy

This paper presents a new synthesis-based approach for writing low-level memory-safe code. Given a partial program with missing guards, our algorithm synthesizes concrete predicates to plug in for the missing guards such that all buffer accesses in the program are memory safe. Furthermore, guards synthesized by our technique are the simplest and weakest among guards that guarantee memory safety...
