GMA Welding of Modified Ferritic and Low Ni Aus...

Gas metal arc welding of new generation modified ferritic stainless steel (FSS) and low nickel austenitic stainless steel (LNiASS) possess challenges to the fabrication industries in terms of cost-effectiveness, quality and performance due to the lack of standardization. The use of an improper combination of process variables like mode of metal transfer, filler material, and shielding gas mixture, often limited the application of these highly potential alloys and increases the fabrication cost. This book is an effort to develop a cost-effective GMAW methodology to achieve high quality welded joints. Three different modes of metal transfer, three different filler materials, and four different shielding gas compositions are studied to obtain the cost-effective combination of GMAW process variables. Several characterization tools and methods are used to realize the performance of various welded joints. This book shows the way to attain cost-effective method to weld modified FSS and LNiASS without deteriorating performance.

Because rarely the information about size's companies and differences between small and medium firms are listed, this study investigates comparative of the effects of audit quality on earnings management and cost of equity capital in two groups of companies (Small Size Companies (SSCs) and Medium Size Companies (MSCs) and also examine the entire sample the economic consequences of auditor choice and received the qualified audit opinion. The differences in the nature of the ownership, agency relations and bankruptcy risks lead MSCs to have weaker incentives than SSCs to engage in earnings management. In addition, investors' pricing of information risk as reflected in the cost of equity capital will be more pronounced for MSCs than for SSCs with high and low audit quality. In this study, of auditor tenure criteria and auditor industry expert as an indicator of audit quality, of the Becker et al and Reynolds and Francis model as an earnings management index and rPEG approach as a benchmark for the cost of equity capital is used. The variables used in this study from financial statements firms listed in Tehran Stock Exchange (TSE).

Low velocity impacts and damage identification ...

In this work an efficient thus computationally low cost FEM modeling technique of both low velocity impacts and Lamb waves propagation events, involving Piezoelectric Wafer Active Sensors (PWAS), is presented. In Chapter 1 both the excitation and sensing of Lamb waves are investigated. The PWAS modeling techniques gave excellent results, as clear from the comparisons with the experimental curves. The great advantage of this modeling is represented by the low computational cost. In Chapter 2 the outputs from PWAS, during low velocity impact events, are investigated. The experimental curves registered during impacts on both aluminum and composite plates were compared with the FEM ones, obtained by considering only geometrical variables of the sensors. In Chapter 3 a test case for damage detection in thin plates with Lamb waves is presented, thus proving the advantage of the PWAS modeling technique for SHM purposes. The substantial improvement of a fast FEM solution is the possibility to directly visualize and study the interaction of Lamb waves with the various kinds of defects/damage eventually present in thin structures such as holes, cracks, delaminations, debondings, etc.

This work aims to assess the Initial Investment Valuation Methodology of the local regulator, facing the results of auctions, due to the high occurrence of low clearing prices observed from 2003 to 2008 and the high percentage of auctions without any bidder recently. The regulator investment forecast defines the maximum value of Yearly Allowed Revenue and the bidder that offers the lowest YAR value wins the auction. The first type of analysis considers project cost, location, execution deadline, transmission line extension and type of all actions from 1999 to 2015, totaling about 3.36 billion USD. It was not found any correlation between those variables and the result of the actions. The second analysis compared the equipment and the additional costs breakdown of the regulator investment forecast with the real investment in projects from 2009 to 2013 and it rarely surpasses 5%. Suggestions are proposed based on the analysis.
