design process is one of the main processes practiced in engineering. in this paper, after demonstrating the place of engineering among the topics discussed about technology, design process is studied from the perspective of three different models. the first model, vincenti’s model, provides an abstract explanation of the design process; the second model, bucciarelli’s model, has a sociological...

Often in modeling the engineering optimization design problems, the value of objective function(s) is not clearly defined in terms of design variables. Instead it is obtained by some numerical analysis such as FE structural analysis, fluid mechanic analysis, and thermodynamic analysis, etc. Yet, the numerical analyses are considerably time consuming to obtain the final value of objective functi...

operator's role in industrial control centers takes place in time, which is one of the most important determinants of whether an expected action is going to be successful or not. in certain situations, due to the complex nature of the work, the existing interfaces and already prepared procedures do not meet the dynamic requirements of operator's cognitive demands, making the control tasks unnec...

fab-less business model in semiconductor industry has led to serious concerns about trustworthy hardware. in untrusted foundries and manufacturing companies, submitted layout may be analyzed and reverse engineered to steal the information of a design or insert malicious trojans. understanding the netlist topology is the ultimate goal of the reverse engineering process. in this paper, we propose...

background: total system design (tsd) factors are design factors, which have impact on overall performance of the power plants in context of total human engineering or macroergonomic. the evaluation of the impact of tsd factors was the main goal of this study. the main objective was human factors engineering on human performance in a power plant. methods : the systems being studied are the cont...

in this paper, some applications of the method of least squares (mls) for the solution of various problems in electromagnetics engineering is briefly reviewed. here, mls is employed for the solution of various problems such as solution of equations, curve fitting to measured data, generalized fourier coefficients, linear operator equations, inegro-differential equations, electrostatics and magn...
