Air Shower

The South Pole air shower experiment (SPASE), a joint Bartol Research Institute and Leeds University project, has been operational since the austral summer of 1987/88. It is a cosmic ray telescope searching for cosmic gamma rays at energies up to 1000 TeV. Although it has a relatively small area (6800 m2), it is situated at an altitude of 2800 m and has a 24 hour coverage, making it very competitive. The angular resolution of 0.°8 at 200 TeV is state-of-the-art in gamma ray astronomy. The astronomical programme includes searches for gamma ray sources, searches for anisotropy in the cosmic ray sky and measuring the energy spectrum over the range 1014-1016 eV.

Planning Methodology

The development and implementation of a methodology by which evacuation planners can assess the sufficiency of their current evacuation plan, identify inadequacies, and define and evaluate potential improvement strategies are discussed. Such goals are accomplished through innovative uses of information technology and the development of a modeling environment that builds on previous work by introducing more representative and efficient algorithms. The new evacuation planning methodology is subsequently applied to a fixed facility incident scenario to demonstrate its applicability to present practice. In this context, several important conclusions are reached, illustrating the importance of having this type of decision-support tool available. Advancements made to the state of the art are assessed and further research needs in this critical and emerging field are identified.

This paper reviews the state of the art of active control systems (ACS) for gas turbine combustors. Specifically, it discusses the manner in which ACS can improve the performance of combustors, the architecture of such ACS, and the designs and promising performance of ACS that have been developed to control combustion instabilities, lean blowout and pattern factor. The paper closes with a discussion of research needs, with emphasis on the integration of utilized engine ACS, health monitoring and prognostication systems into a single control system that could survive in the harsh combustor environment.

Building Life Cycle

Recent years, many infrastructures, say building structures and bridge structures, have suffered from multi-hazards. According to official reports, 286 fires broke out due to the 2011 off the Pacific coast of Tohoku Earthquake, and fire after 1995 Kobe earthquake destroyed almost 7000 buildings. Current design codes treat earthquakes, fires and explosions as completely independent. The application of multi-hazard design is essential for improving the safety of structures, reducing building life cycle costs and increasing efficiency. In this paper, some influential multi-hazard incidents are described primarily, and the state-of-the-art and research needs on multi-hazard design are presented.
