Fu, X. 2017. Self-rated health and respiratory symptoms among civil aviation pilots. Occupational and non-occupational risk factors. 79 pp. : Uppsala University. There is concern about the indoor environment in aircraft but few stud-ies exist on self-rated health (SRH) and respiratory symptoms among pilots. Occupational and non-occupational risk factors for SRH, respira-tory symptoms and other ...

Attributable to their strong electrical activity, neurons have long been seen as the main determinants of brain function. Over the last decades, however, this view changed dramatically. A variety of specific roles have been assigned to different types of glial cells. Astrocytes constitute the link between the vascular system and neighboring neurons. They determine ion and transmitter homeostasi...

tern generation (ATPG) has yielded effective solutions for combinational circuits, developing efficient methods for sequential circuits remains difficult. The difficulty results because state and time frame expansion has caused a virtual explosion of the relevant search space. The commonly used branch-and-bound technique1 is infeasible for large sequential circuits because of the exponentially ...

An overview on surveillance in different areas is given. Even though methods have been developed under different scientific cultures, the statistical concepts can be the same. When the statistical problems are the same, progress in one area can be used also in other areas. The aim of surveillance is to detect an important change in an underlying process as soon as possible after the change has ...

The aircraft industry is viewed as a prestigious industry by many countries. Emerging economies regard the establishment of aircraft production capabilities as contributing to their competitiveness and technological development. Therefore, in the defence aircraft industry, politics play a key role in competitiveness. Governments can strategically trade market access for technological developmen...

BIOGRAPHY Jan Palmqvist received his M.Sc. in Applied Physics and Electrical Engineering from Linkk oping University , Sweden in 1986. He has been with Saab Military Aircraft since 1989 and in 1994 he also joined the Automatic Control Group at Linkk oping University as a part time Ph.D. student. His current research focuses on algorithms for integrity monitoring of integrated navigation systems...

A longitudinal study of the international behaviour of Swedish suppliers is presented. Three different types of supplier are identified: simple suppliers, advanced suppliers, and own product suppliers. Factors influencing the internationalisation of these suppliers are discussed. It is concluded that the firms’ offer and the customers’ buying strategies influence the firms’ international behavi...

Preface The thesis has been developed as part of the requirements for a PhD degree at the Artificial Intelligence and Integrated Computer System division (AIICS) in the The work focuses on issues related to Unmanned Aerial Vehicle (UAV) navigation, in particular in the areas of guidance and vision-based autonomous flight in situations of short and long term GPS outage. The thesis is divided int...

Leaf-off individual trees in a deciduous forest in the eastern USA are detected and analysed in small footprint, high sampling density lidar data. The data were acquired February 1, 2001, using a SAAB TopEye laser profiling system, with a sampling density of approximately 12 returns per square meter. The sparse and complex configuration of the branches of the leaf-off forest provides sufficient...

Work undertaken by Lotus Engineering and partners has shown that the miscibility of the low-carbon-number alcohols with gasoline provides a powerful tool to enable the introduction of methanol as a transport fuel in a wholly evolutionary manner. This is primarily facilitated by the fact that the CAFÉ regulations in the US (together with other incentives in other countries, such as Sweden) have ...
