The new challenge of the Gas Turbine industry is to develop new technologies for meeting electricity demand growth and reducing harmful emissions. Thus, a better understanding of the combustion phenomenon and an improvement in simulation capabilities are needed. In this paper, we present a new technique that is computationally efficient, for capturing the thermo-acoustic waves in low Mach number c

The enzyme dUTPase catalyzes the hydrolysis of dUTP to dUMP and pyrophosphate, thereby preventing a deleterious incorporation of uracil into DNA. The best known dUTPase is that from Escherichia coli, which, like the human enzyme, consists of three identical subunits. In the present work, the catalytic properties of the E. coli dUTPase were investigated in the pH range 5-11. The enzyme was found to

The increasing test data volume needed to test core-based System-on-Chip contributes to long test application times (TAT) and huge automatic test equipment (ATE) memory requirements. TAT and ATE memory requirement can be reduced by test architecture design, test scheduling, sharing the same tests among several cores, and test data compression. We propose, in contrast to previous work that addresse

This paper presents a phase noise analysis of the very popular differential LC-tank CMOS oscillator. Closed-forms formulas for the phase noise in the 1/f2 region are derived under very general assumptions.

By means of a myograph, postjunctional alpha-adrenoceptors were characterized in human superficial epigastric arteries and veins obtained from health subjects. The rank order of potency of subtype selective agonists could not be used for receptor characterization in these vessels, whereas antagonists gave distinct results. It was found that the arteries were endowed mainly by alph1-adrenoceptors b

Popular Abstract in Swedish Avhandlingens huvudsyfte är att försöka utreda hur man kommer till förståelse av det historiska huset och att diskutera vilken roll den historiska dokumentationen spelar i restaureringsprojekteringen. I restaurering som i allt annat arbete med arkitektur är förståelse ett nyckelord. Förståelse för de särskilda förutsättningar som ligger i uppgiften, i objektet, i skapanThe principal aim of the thesis is to evaluate the significance of the documentation of a building’s history for the work of restoring it and caring for it. Thus it may be said to address restoration as a hermeneutical problem, besides considering the relationships between the work of documentation; analyses of the resulting data; and the creative process in which the ideology of restoration is im

In this work, we present a method for estimating the parameters detailing an unknown number of linear chirp signals, using an iterative sparse reconstruction framework. The proposed method is initiated by a re-weighted Lasso approach, and then use an iterative relaxation-based refining step to allow for high resolution estimates. The resulting estimates are found to be statistically efficient, ach
