Real-time applications introduce new requirements on wireless networks and impose quality thresholds on parameters like delay, jitter, throughput, and packet loss in order to run smoothly. This paper addresses this issue by presenting a MAC scheme that offers real-time applications the opportunity to reserve transmission time based on their QoS requirements for contention-free medium access. Our s
The chapter on Swedish employers' associations contains a calculation on collective bargaining coverage in 1995. Despite the absence of state extension mechanisms collective agreements in 1995 covered as much as 90 per cent of all private sector employees (p. 211). Including the public sector the rate was 94 per cent. The same year the density of employers' organisations was 77 per cent, i.e. 77 p
This dissertation is about the antagonistic conceptions of men’s violence against women – rape, incest and physical assault – as has been expressed by different actors in Sweden from 1975 – 2000. Mainly, my interest lies in how and why these conceptions have been articulated. During the studied period the attention to men’s violence against women as a question of gender, has grown remarkably. For
Two new African species of Teloschistes are described: T. arabicus Frödén sp. nov. and T. inflatus Frödén sp. nov. T. arabicus is a montane species, occurring in the southern parts of the Arabian peninsula and the adjacent parts of eastern Africa. T. inflatus is only known from South Africa, and was previously included in T. perrugosus Müll.Arg. Useful characters for distinguishing the misundersto
Analysis of interconnected dynamical systems is considered. A framework for the analysis of stability of the interconnection is given. The results of Fax and Murray that studies the SISO-case for a constant interconnection matrix are generalized to the MIMO-case where arbitrary interconnection is allowed. The analysis shows the existence of a separation principle that is very useful in the sense o
We propose a method for detection of the degree of infection in the paranasal sinuses utilizing a previously published method whereby the viscosity in a sealed container may be measured using an ultrasound Doppler method. As ultrasound propagates in a liquid medium, due to attenuation, the resulting pressure gradient will cause the liquid to move in the propagation direction - the wellknown effect
Intermetallic compounds are a distinct group of materials having attractive properties and wide applications. In the present work, the formation of intermetallic compounds from elemental components in Cu-Al, Ni-Al and Ni-Ti systems has been studied. Metallic powders were mixed in stoichiometric ratios corresponding to CuAl2, NiAl and NiTi. Calorimetric studies were made using compacted disks as we
