On two groups of the form 2 8 : A 9
No full textThis paper is dealing with two split extensions of the form 28:A9. We refer to these two groups by G¯¯¯¯1 and G¯¯¯¯2. For G¯¯¯¯1, the 8-dimensional GF(2)-module is in fact the deleted permutation module for A9. We firstly determine the conjugacy classes of G¯¯¯¯1 and G¯¯¯¯2 using the coset analysis technique. The structures of inertia factor groups were determined for the two extensions. The inertia factor groups of G¯¯¯¯1 are A9,A8,S7,(A6×3):2 and (A5×A4):2, while the inertia factor groups of G¯¯¯¯2 are A9,PSL(2,8):3 and 23:GL(3,2). We then determine the Fischer matrices for these two groups and apply the Clifford–Fischer theory to compute the ordinary character tables of G¯¯¯¯1 and G¯¯¯¯2. The Fischer matrices of G¯¯¯¯1 and G¯¯¯¯2 are all integer valued, with sizes ranging from 1 to 9 and from 1 to 4 respectively. The full character tables of G¯¯¯¯1 and G¯¯¯¯2 are 84×84 and 40×40 complex valued matrices respectively

Monitoring the development of microcracks in reinforced concrete caused by sustained loading and chloride induced corrosion
No full textChloride-induced corrosion of steel in reinforced concrete structures is one of the main problems affecting their durability and it has been studied for decades, but most of them have focused on concrete without cracking or not subjected to any structural load. In fact, concrete structures are subjected to various types of loads, which lead to cracking when the tensile stress in concrete exceeds its tensile strength. Cracking could increase transport properties of concrete and accelerate the ingress of harmful substances (Cl -, O2, H2 O, CO2). This could initiate and accelerate different types of deterioration processes in concrete, including corrosion of steel reinforcement. The expansive products generated by the deterioration processes themselves can initiate cracking. The success of concrete patch repairs can also influence microcracking at the interface as well as the patch repair itself. Therefore, monitoring the development of microcracking in reinforced concrete members is extremely useful to assess the defects and deterioration in concrete structures. In this paper, concrete beams made using 4 different mixes were subjected to three levels of sustained lateral loading (0%, 50% and 100% of the load that can induce a crack with width of 0.1mmon the tension surface of beams - F 0.1) and weekly cycles of wetting (1 day)/drying (6 days) with chloride solution. The development of microcracking on the surface of concrete was monitored using the Autoclam Permeability System at every two weeks for 60 weeks. The ultrasonic pulse velocity of the concrete was also measured along the beam by using the indirect method during the test period. The results indicated that the Autoclam Permeability System was able to detect the development of microcracks caused by both sustained loading and chloride induced corrosion of steel in concrete. However, this was not the case with the ultrasonic method used in the work (indirect method applied along the beam); it was sensitive to microcracking caused by sustained loading but not due to corrosion.</p
An investigation of delay fault testing for multi voltage design
No full textMulti Voltage Design (MVD) has been successfully applied in contemporary processors as a technique to reduce energy consumption. This work is aimed at finding a generalised delay testing method for MVD. There has been little work to date on testing such systems, but testing the smallest number of operating voltages reduces testing costs. In the initial stage, the impact of varying supply voltage on different types of physical defects is analysed. Simulation results indicate that it is necessary to conduct test at more than one operating voltage and the lowest operating voltage does not necessarily give the best fault coverage. The second part of this work is related to the issues in the testing of level shifters in a MVD environment. The testing of level shifters was analysed to determine if high test coverage can be achieved at a single supply voltage. Resistive opens and shorts were considered and it was shown that, for testing purposes, consideration of purely digital fault effects is sufficient. Multiple faults were also considered. In all cases, it can be concluded that a single supply voltage is sufficient to test the level shifters. To further enhance the quality of test, we have proposed fault modelling and simulations using VHDL-AMS. Our simulation results show that the model derived using simplified VHDL-AMS gives acceptable results and significantly reduces the fault simulations time
