in this paper, dissimilar resistance spot welding of aisi 1075 eutectoid steel to aisi 201 stainless steel is investigated experimentally. for this purpose, the experiments are designed using response surface methodology and based on four-factor, five-level central composite design. the effects of process parameters such as welding current, welding time, cooling time and electrode force are inv...

Using life satisfaction as a direct measure of individual utility has become popular in the empirical economic literature. In this context, it is crucial to know what circumstances or changes the measure is sensitive to. Is life satisfaction a volatile concept that is affected by minor changes in life circumstances? Or is it a reliable measure of personal happiness? This paper will analyze the ...

H. Gołaś, A. Mazur, B. Mrugalska, Faculty of Engineering Management, Poznan University of Technology, Poznan, Poland The aim of the paper is to highlight the significance of implication of risk analysis and quality control methods for the improvement of parameters of lead molding process. For this reason, Fault Mode and Effect Analysis (FMEA) was developed in the conceptual stage of a new produ...

-In present era of automation and modernization, setting up of production plants involves huge capital investment especially for the process industry. The deterioration and failure of these systems might incur high costs due to production losses and delays, unplanned intervention on the system and safety hazards .The causes of failure may be human error, poor maintenance, inadequate testing, in...

Various calendar effects of stock markets were widely studied in the past. However, most of the previous studies use traditional methods such as regression. Furthermore, only a few of them studied Asian countries. This study investigates calendar effects, in particular, Halloween and January effects, on securitized real estate indices of eight economies (five of which are Asian economies): Hong...

Failure modes and effects analysis (FMEA) is used in the manufacturing industry to improve product quality and productivity. However, the traditional approach has many shortcomings that affect its effectiveness and limit its usefulness, especially in the early stages of design. Automating the FMEA report generation process seems to answer some of these problems, and there has been much past and...

Tasks like diagnosis, failure-modes-and-effects analysis (FMEA), and therapy proposal involve reasoning about variables and parameters deviating from some reference state. In model-based systems, one tries to capture this kind of inferences by models that describe how such deviations are emerging and propagated through a system. Several techniques and systems have been developed that address th...
