Emerging wireless sensor and actuator network (WSAN) technology has the potential to enable semi-autonomous air-flow control to improve the aerodynamic performance of aircraft. In this paper, a WSAN topology comprising of multiple linear sensor clusters terminated by actuators is proposed for active flow control. Two interference aware convergecast scheduling strategies are presented and analyzed,

There is an increasing challenge for chemical industry and research institutions to find cost-efficient and environmentally sound methods of converting natural resources into fuels chemicals and energy. Catalysts are essential to these processes and the Catalysis Specialist Periodical Report series serves to highlight major developments in this area. This series provides systematic and detailed re

The S.T.A.R. Design Studio (Space and Terrestrial Architectural Research) studies pre-industrial habitats in i.a. Tanzania, and develops design concepts for future habitats in space in cooperation with Johnson Space Centre, Houston, Texas. In both cases our studies focus on "extreme" circumstances. Perhaps studying the conditions of a crew sealed in a capsule can better prepare us for the problems

As part of systematic endeavor to Islamize the society, Iranian Islamic government has bestowed efforts to create gender-segregated public urban spaces. The gender segregation was formally enforced in public places such as schools, sport halls, swimming pools, transportation facilities, etc. in last three decades. The most recent effort of the government includes “women-only parks”, claimed to be

Public transport plays a major role in sustainable development of urban areas. However, transportation and infrastructure have to be efficient and in line with the wishes and demand of passengers. Local people have knowledge and experiences of the quality of services they want. When locals are involved, they include grass-root knowledge about ecology, environment, local livelihood problems and res

Review of Kristina Jonsson, "Pratices for the Living and the Dead. Medieval and Post-reformation Burials in Scandinavia" (Stockholm 2009). The review is based on the faculty-opposition.

The environmental problems associated with office furniture consumption call for a more efficient use of office furniture that can decrease emissions and,volume of waste. The author discusses the opportunities and barriers for the implementation of a PSS for office furniture. In addition, the paper identifies possibilities to overcome these barriers. The article is based on interviews with Europea

The performance of a turbo code can be severely degraded if no trellis termination is employed. This paper investigates the implications of the choice of trellis termination method for turbo codes, and explains the origin of the performance degradation often experienced without trellis termination. An efficient method to derive the distance spectrum of turbo codes for different trellis termination
