It has been proposed that six co-located antennas, namely three electric and three magnetic dipoles, can offer up to a six-fold capacity increase in wireless channels, relative to that of single antennas. In other words, six degrees of freedom (DOFs) can be supported by co-located six-port transmit and receive antenna arrays. However, due to the complexity in designing and measuring such a six-por

Within the framework of HASTA, a systematic study was conducted about Swedish municipalities’ traffic strategies and use of sustainability indicators to follow up the work on a sustainable transport system. This report analyzes the work of the municipalities with a traffic strategy in order to examine if the municipalities use sustainability indicators or not. Furthermore, the report analyzes in w

The thesis aims at creating a large-scale GIS database covering Amazonian prehistory between 2000 BC and AD 1700 in order to be able to test the hypothesis of ethnic circumscription described above. This database will be compiled of geographically positioned material from archaeology (datings, ceramic styles, tempering materials, rock art, anthropogenic soils, and other visual aspects of material

A common way to cool the tip is to use serpentine passages with 180-deg turn under the blade tip-cap. Improving internal convective cooling is therefore required to increase the blade tip life. In this paper, augmented heat transfer of a blade tip has been investigated numerically. The computational models consist of a two-pass channel with 180-deg turn and pin-fins mounted on the tip-cap, and a s

Institution ger 250 miljoner träffar på sökmotorn Google. I vilka sammanhang används detta slitstarka ord och vilka betydelser bär det på? I den här boken undersöks institutioner som platser, rum och organisationer samt begreppets vetenskapliga utveckling och användning. Institutioner representerar ofta socialt tvång, beständighet över tid och reglering av aktörers handlande.

Nationality originated along with development of the modern nation-State. However, growing global migration, travel and increasing communications have led to creation of multiple individual loyalties in addition to national identity. This is further facilitated by mobility of capital, foreign investment, and establishment of transnational corporations. Dismantling national borders and granting di

We derive explicit density evolution equations for protograph-based generalized LDPC codes on the binary erasure channel. They are obtained from an analysis of multi-dimensional input/output transfer functions of the component decoders. Belief propagation decoding with optimal component APP decoders is considered. Based on the resulting transfer functions, a threshold analysis is performed for som
