We present a method to compute, quickly and efficiently, the mutual information achieved by an IID (independent identically distributed) complex Gaussian input on a block Rayleigh-faded channel. The method accommodates both scalar and MIMO (multiple-input multiple-output) settings. Operationally, the mutual information thus computed represents the highest spectral efficiency that can be attained u

Polarization vision is the ability of animals to detect the oscillation plane of the electric field vector of light (E-vector) and use it for behavioral responses. This ability is widespread across animal taxa but is particularly prominent within invertebrates, especially arthropods. Polarized light can be either used implicitly for enhancing image contrast and for adding another dimension to the

The Swedish state and its administrative organization experienced, like its European neighbours, an extensive development and transformation in the beginning of the 17th century. One part of the administration that for the first time was organised in a formal way was the postal services. This paper discuss the origins of national postal systems in relation to the development of bureaucratic and ad

EG-domstolen har i hög grad utvecklat EG-rätten med stöd av allmänna rättsprinciper som erkänns av medlemsländerna. Man kan lite tillspetsat säga att EG-domstolen har använt rättsprinciperna som styrmedel när den har utvecklat EG-rätten. I denna bok analyseras EG-domstolens användning av allmänna rättsprinciper i en mängd olika situationer. Vilken betydelse har t.ex. rättsprinciperna när EG-domsto

An ongoing continuous process of automatization of the production lines is used in industry to reduce production costs. Automatization of quality control should be seen as part of a cost reduction process, as well as of quality control of the welding. Mostly the time-consuming and expensive checking procedure of the weld joint is carried out off-line by an experienced welding operator. The need fo

Advanced radio system designs have been proposed that are intended to overcome or even take advantage of the radio channel caused by multipath effects in urban environments to achieve even higher performance. We present analytical expressions for the angle-of-arrival power density function (PDF) and general analysis for time of arrival (expressed in terms of distance) respectively, for the channel

Belief revision theory and philosophy of science both aspire to shed light on the dynamics of knowledge – on how our view of the world changes (typically) in the light of new evidence. Yet these two areas of research have long seemed strangely detached from each other, as witnessed by the small number of cross-references and researchers working in both domains. One may speculate as to what has bro

Cellular neural networks are widely used with real-time image processing's applications. Such systems can be efficiently realized using macro enriched field-programmable gate-arrays. This paper explores the benefits of packet switching and discusses its advantages over a current design based on circuit switching. The implementation is performed using Xilinx Virtex-II Pro P30 and handles around 500

In any research field the transformation of raw data into conclusions is a critical phase, necessitating a systematic approach. The basic question is: How can I as a (design) researcher corroborate my conclusions? This paper is based on a study of the analytical/interpretative portion of papers published in the Proceedings of the 2006 Design & Emotion Conference. We investigate how the authors
