The paper presents the system of Composite Graph Grammars (CGG) modelling the adaptive two dimensional hp Finite Element Method algorithms (h p-FEM) with triangular and rectangular finite elements. A computational mesh is represented by a composite graph. The operations performed over the mesh are defined by the graph grammar rules. The CGG-system contains different graph grammars corresponding to different kinds of operations performed over different types of elements. These grammars allows one to generate structures of initial mesh, rectangular and triangular elements, to identify common edges of adjacent elements as well as to break elements (h-adaptation). The paper is concluded with numerical results concerning the 2D crack problem.

After the LHC luminosity upgrade the number of readout channels in the ATLAS Inner Detector will be increased by one order of magnitude and delivering the power to the front-end electronics as well as cooling will become a critical system issue. Therefore a new solution for powering the readout electronics has to be worked out. Two main approaches for the power distribution are under development, the serial powering of a chain of modules and the parallel powering with a DC-DC conversion stage on the detector. In both cases switched-capacitor converters in the CMOS front-end chips will be used. In the paper we present the design study of a step-up charge pump and a step-down converter. In optimized designs power efficiency of 85 % for the step-up converter and 92 % for the step-down converter has been achieved.
In the case of standalone houses, ensuring a continuous and regulated power supply from renewable sources is crucial. To address their unpredictable nature, an environmentally conscious hybrid renewable energy system ...
