Sammanfattning-The use of hierarchical structures for providing excellent wireless connections for customers has attained growing attention. Models to investigate the QoS requirements rather quickly become complicated and hard to analyze. In the paper a first rough analytical approach for the answer is given. As the users devote more and more time to be connected through wireless connections, and

To meet the constant demand for performance, it is increasingly common with multi-processor system- on-chips (MPSoCs). As these integrated circuits (ICs) may contain billions of transistors squeezed on a few square centimeters, it is difficult to ensure that they are correct. Defects may escape manufacturing test or develop during operation and, further, ICs manufactured in later semiconductor tec

Normalt sett föreställer man sig att det finns ett samband mellan ord och handling. Det skulle betyda att människor som säger sig vara miljöengagerade också tar miljöhänsyn i vardagslivets handlingar. Man kan emellertid konstatera att vägen från ord till handling är kantad av många slags överväganden som leder till skillnader mellan det man säger sig tycka och vad man sedan gör. Mellan attityd och

Det finns en diskrepans mellan vilka tekniska hjälpmedel och innovationer äldre människor verkligen vill ha, och vad omgivningen tror att de behöver. Nutidens befolkningspyramid antar en alltmer fyrkantig form och många av oss kan vid pensioneringen se fram emot ytterligare en tredjedel av vuxenlivet. Därför har den tekniska utvecklingen och äldres teknikanvändning kommit att bli ett aktuellt fors

In an exploratory investigation of personality patterns, Swedish air force pilots (n = 22) and ground officers (n = 14) were tested with the Creative Functioning Test, the Serial Color Word test, and the Spiral After-Effect Technique. The participants also answered open questions about their work and about creativity related items. Achievement ratings were made by their superior officers. An initi

“The death of distance” has become the battle cry of a modern generation of managers, policy makers and scientists who embrace the new globalized economy and its promise of frictionless exchange across the world. While highly influential, this view does not, however, stand unchallenged. Over the last 15 years, there has been a growing interest in the geographical clustering of industry. Well-known

In this paper, it is shown that tapered resistive sheets at the edges of the array can be used to transform the scattering properties of the antenna or the radome to that of a metallic plate and hence reduce the radar cross section. Numerical examples of a bandpass FSS radome are presented to illustrate the results. The RCS reduction is very good for TE polarization but not as efficient for the TM
