This article explores, through a case study, measures of energy efficiency in data processing centers. An analysis of this case demonstrates how the design criteria could improve the rate of consumption in IT centers, which is currently the second most contaminating industry on the planet, and is the responsible for 2% of CO2 emissions, surpassed only by the aeronautical industry. The present and future situation of IT center energy consumption and associated environmental effects is analyzed, and also looks at how state-of-the-art technology, correctly implemented, could ensure significant rationalization of data processing center energy consumption. The article will examine optimization techniques, specific problems and case studies.

Two-dimensional polyacrylamide gel electrophoresis of proteins is a robust and reproducible technique. It is the most widely used separation tool in proteomics. Current efforts in the field are directed at development of tools for expanding the range of proteins accessible with two-dimensional gels. Proteomics was built around the two-dimensional gel. The idea that multiple proteins can be analyzed in parallel grew from two-dimensional gel maps. Proteomics researchers needed to identify interested protein spots by examining the gel. This is time consuming, labor extensive and error prone. It is desired that the computer can analyze the proteins automatically by first detecting then quantifying the protein spots in the 2-D gel images. In our previous work, we presented a new technique for segmentation of 2-D gel images using the fuzzy c-means algorithm using the notion of fuzzy relations. In this paper, we will describe the new relational fuzzy c-means algorithm (RFCM) and use it for automatic protein spots quantification. We will also use two methods to evaluate its performance: the unsupervised evaluation method and comparison with the expert spots quantification.

This work presents the co-simulation approach to the analysis of control systems containing detailed models of electromagnetic and electromechanical converters. In this method of analysis the attention is paid to the whole system and not only to its electromagnetic part. The latter is described by equations resulted from the two-dimensional finite element discretisation of the Maxwell equations, and is coupled weakly with the remaining part of the system. The simulation is carried out in Matlab/Simulink environment wherein the coupling is realised through the S-function. Example results regarding simulation of the operation of the control system of an electrical machine and the operation of a power electronic converter are presented and compared with available reference data.
The main objective of this work is the design and implementation of a hierarchical control solution for chemical and petrochemical processes, namely the control and optimization of the ethylene pyrolysis reactor, the ...

In this paper we present a means of visually representing information associated with the state and functionality of the myocardium in the left ventricular chamber of the heart. Starting from segmentation contours which outline the endocardium and the epicardium for several slices and over several phases of motion and stress levels, we construct two surfaces which approximate the shape of the left ventricular wall. Several parameters, such as the thickness, thickening or motion speed of the wall are computed from the contours, and the resulting values are represented on the outer, epicardium surface using methods such as color encoding or so-called "stress bands". The distribution of colors on the outer surface is analogous to the distribution of parameter values along the left ventricular wall. A visual inspection of said colors, depending on the particularities of the analyzed data set, may render visible anomalies or dyssynchronies, or otherwise offer relevant indications on the behavior of the wall across multiple phases of the contraction-dilation cycle and for several levels of strain. The approaches described are meant to provide an alternative and intuitive visual aid in the diagnosis and treatment of cardiovascular diseases.
