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

Popular Abstract in Swedish Denna avhandling behandlar komplexa optimerings problem med artificiella neuron nätverk (ANN) tekniker och diverse verktyg från den teoretiska fysiken. För många typer av komplexa optimerings problem kan den mänskliga hjärnan prestera ett snabbt och hyfsat bra svar. ANN bygger på en mycket rudimentär bild av hur det riktiga de riktiga neuronerna i hjärnan arbetar, syftPotts mean field artificial neural network techniques are developed and applied to airline crew scheduling problems and routing problems. A propagator formalism in terms of Potts neurons is developed to handle global topological issues. An integrated method for identifying and classifying ECG complexes is presented. Unsupervised self-organizing artificial neural networks are employed to cluster t

A method for assessing disturbances in SISO loops has been developed. The method indicates if the SISO loop under consideration will benefit from an addition of feedforward control from a measured disturbance. An implementation in Java of the methodology is presented in the paper.
