We analyse the iterative decoding performance of conventional rate R=1/3 turbo codes, when both code length and number of iterations tend to infinity. To obtain a rigorous bound on the iterative limit, we introduce a two-phase decoding algorithm which can be analyzed asymptotically

Centralized Petersen coil earthing in networks with extensive use of underground cable involves flow of large quantities of reactive earth fault current. In networks with long radial cable feeders this creates problems involving active losses and active and reactive earth fault current. One possible solution to the problem is the use of local compensation. This paper aims at understanding the limi

Multiplexing efficiency has recently been proposed as a performance metric for characterizing the absolute efficiency of MIMO antennas in a reference channel. In this work, we generalize this metric to account for arbitrary propagation channels, so the impact of the channel can also be studied. Using the extended definition of multiplexing efficiency, the respective roles of effective antenna gain

We propose new feature-based methods for rigid and affine image registration. These are compared to state-of-the-art intensity-based techniques as well as existing feature-based methods. On challenging datasets of brain MR and whole-body CT images, a significant improvement in terms of speed, robustness to outlier structures and dependence on initialization is shown.

Why is waste such an important topic for understanding the management of overflow? First, because waste is a classic symbol of overflow: to be flooded with too much stuff that demands handling, sorting, and decision-making is a feeling well known in consumer society. Facts and figures speak of the same overflow. Waste disposal is a growing problem. The downside of consumption is a growing mountain

Directions are given for demonstrating various topics from the other book chapters: The wave-nature of light, singlet oxygen, chromatic adaptation of cyanobacteria, the properties of the human visual system, photoconversion of rhodopsin, photosynthesis of previtamin D, spectral properties of chlorophyll, photoconversion of protochlorophyllide, separation of chloroplast pigments, photoadaptation of

Glucosinolates are natural plant products that function in the defense toward herbivores and pathogens. Plant defense is regulated by multiple signal transduction pathways in which salicylic acid (SA), jasmonic acid, and ethylene function as signaling molecules. Glucosinolate content was analyzed in Arabidopsis wild-type plants in response to single or combinatorial treatments with methyljasmonate

The construction and demonstration of a conductometric chemical sensor based on a molecularly imprinted polymer (MIP) is reported. Benzyltriphenylphosphonium ions, chosen as a model, were used as the analyte. The MIP based sensors gave, when exposed to the analyte, a significantly higher conductivity reading than the reference sensors. Furthermore, the use of molecularly imprinted polymers as arti
