The degree of disease risk represented by the introduction, spread, or establishment of one or several diseases through the importation of animals and animal products is assessed by importing countries through an analysis of risk. The components of a risk analysis include hazard identification, risk assessment, risk management, and risk communication. A risk assessment starts with identificatio...

Background; Prevention of accidents—a crucial requirement in oil industries—involves hazard recognition, risk assessment, and corrective actions. The purpose of this study was to compare the ETBA and HAZOP techniques for risk assessment in a gasoline refinery unit. Methods; In this case study, data were collected using process flow diagram, walking–talking through method, piping and instrument...

Elicitation of requirements for safety critical aeroengine control systems is dependent on the capture of core design intent and the systematic derivation of requirements addressing hazardous deviations from that intent. Derivation of these requirements is inextricably linked to the safety assessment process. Conventional civil aerospace practice (as advocated by guidelines such as ARP4754 and ...

An erosion hazard index methodology (EHIM) was developed for assessing stream erosion. The index of stream erosion is designed as a management tool. Assessing stream erosion involves consideration of a range of aspects of streams and a value judgment about a desirable state. The assessment of the erosion indicators of streams was based on a state-wide assessment of physical stream condition. A ...

Risk assessment is mainly based on certain scenarios involving an event of a certain size which is thought to be characteristic for the considered type of hazard. However, many natural hazards extend over a wide range of event sizes, and some of them are even free of characteristic scales. An expression for the risk taking into account various event sizes is derived, and its implications on ris...

The paper presents some results of investigations regarding the development of a method for ships safety estimation in critical conditions. The objectives of investigations are briefly described including the method introduction. Special attention is paid towards application of the direct and indirect methods. Four modules of the computational model are presented including those connected with ...

risk assessment provides the possibility of planning and management to prevent and reduce the risk of desertification. the present study is aimed to assess the hazard and risk of desertification and to develop management programs in the semi-arid western regions of golestan province in iran. desertification rate was obtained using the iranian model of desertification potential assessment. since...

According to Iranian code of practice for seismic resistant design of buildings standard No. 2800, Yazd is located in the place with the medium earthquake hazard [1]. Due to the position of Yazd with many historical and important buildings, maintaining these traditional heritages is an important task in civil engineering field. On account of these mentioned valuable buildings and region potenti...
