Radiation efficiency and surface waves for patch antennas on inhomogeneous substrat

In this paper the surface wave characteristics, as well as the radiation efficiency and the directivity of a patch antenna, with a given current distribution, located on top of an inhomogeneous, isotropic substrate are calculated. The substrate is infinite in the lateral directions and inhomogeneous with respect to the height coordinate. The surface waves in the substrate are analyzed using the pro

A Low Complexity Soft-Output MIMO Decoding Algorithm

The K-best Schnoff-Euchner (KSE) decoding algorithm is shown to be capable of supporting soft-outputs for MIMO detection. A modified KSE (MKSE) decoding algorithm is further proposed to improve the performance of the soft-output KSE with minor modifications. Simulation results show that the proposed MKSE algorithm can approach near-optimal performance with lower complexity and is suitable for code

Organization of centromere associated DNA in Chironomus pallidivittatus.

Centromeres have not yet been functionally defined in higher eu- karyotes, largely due to the huge amounts of repeated DNA in these regions of most species and difficulties of delimiting centromeric from pericentric regions. Also the latter have large quantities of mostly noncoding DNA, expressed cytologically as pericentric heterochromatin. The dipteran Chironomus pallidivittatus is advantageous

Macrophage Responses to Interferon-gamma are Dependent on Cystatin C Levels.

The aim of the present investigation was to elucidate possible effects of cystatin C on inflammatory responses mediated by macrophages. Previously it has been shown that in vitro treatment of murine peritoneal macrophages with interferon-gamma (IFN-gamma) causes a down-regulation of cystatin C secretion. To investigate whether such changes in cystatin C expression in turn can affect inflammatory r

Bioreduction of carbonyl compounds to chiral alcohols by whole yeasts cells: process optimisation, strain design and non-conventional yeast screening

Chiral building blocks are needed for the production of drugs and fine chemicals, which requires the use of several synthetic routes to produce a specific enantiomer of interest. One promising approach to introduce chirality into molecules is the stereo-selective whole cell bioreduction of carbonyl compounds or ketones to the corresponding chiral alcohols. The aim of this thesis was to develop eff

Reconstruction of equivalent currents using a near-field data transformation - with radome applications

Knowledge of the current distribution on a radome can be used to improve radome design, detect manufacturing errors, and to verify numerical simulations. In this paper, the transformation from near-field data to its equivalent current distribution on a surface, i.e., the radome, is analyzed. The transformation is based on the surface integral representation that relates the equivalent currents to t
