Biomass gasification stations are facing many hazard factors, therefore, it is necessary to make hazard assessment for them. In this study, a novel hazard assessment method called extended set pair analysis (ESPA) is proposed based on set pair analysis (SPA). However, the calculation of the connection degree (CD) requires the classification of hazard grades and their corresponding thresholds us...

quantitative assessment is the most important means to identify hazard potential and manage risk for an industrial process. the implement of quantitative assessment in the early stage will help to develop inherently safer process, eliminating the hazard and reduce the possibility of accidental chain events and the magnitude of consequences. in this paper, after reviewing the presently available...

Abstract The occurrence of coal burst in underground mines is complex, abrupt, and diverse, the evaluation prediction hazard premise effective prevention control burst. In this study, a carrier system model under synergistic action roof, seams, floor was established, evolution discussed based on stress-vibration-energy coupling principle. On basis, an integration method bursting strain energy s...

Impacts generated by natural hazards in the last years are growing also because many regions of the world become subject to multiple hazards and cascading effects. The modelling of the multi-hazard dimension is a new challenge that allows the stakeholder to face with the chain effects between hazards and to model the risk in a real holistic way. Despite the recognition of the importance of a mu...

Forest fire risk assessment is an important task for forest fire management and planning. This paper presents current work on the definition and implementation of forest fire risk assessment models in the Wildfire Analyst TM software with the purpose of providing support and increased value in risk assessment. Three models are presented based on the concept of forest fire risk: forest fire stru...

Archaeological excavation documentation poses several challenges to spatial data management. This work gives a data model, respective query functionality and the description of the resulting prototype system for recording and analyzing the data produced during the course of an excavation. Based on a requirements analysis, we develop a data model that not only captures georeferenced finds (potte...

This paper discusses the development of excavation techniques in England and their application to historical archaeology in Australia. Edward Higginbotham, a consultant archaeologist in Sydney, applies his experience of excavations in both countries to a critical analysis of various excavation methods, including test-pits, trial-trenches, the grid method, and area excavation. The advantages, ef...

T. Bredfeldt Texas Commission on Environmental Quality, MC-168, P.O Box 13087, Austin, TX 78711-3087, USA e-mail: [email protected] Abstract Hazard identification is considered an early step in the risk assessment process. The primary goal of this step is to determine whether exposure to a chemical is likely to cause a specific adverse health effect in humans. The process of hazard ide...

This paper provides a tractable framework to study optimal risk sharing between an investor and a firm with general utility forms in the presence of moral hazard under market risk and jump risk. We show that, for a two-date discrete-time moral hazard model, there exists a continuous-time model that obtains the same optimal result. Moreover, we characterize the optimal risk sharing explicitly, i...
