The thermal characterization of electric and electronic devices is an important topic during the training of future electric and electronic engineers, especially in technology subjects. In the industry and accredited laboratories, the thermal tests are carried out with environmental screening process and testing systems into special chambers. However, these test systems are not usually available for didactic purposes due to mainly their acquisition and maintenance cost. Consequently, a new test system for thermal characterization in didactic laboratories has been designed. This new system is simple, intuitive, and economically viable for universities and formation centres. Students, among other aspects, can analyze how temperature affects some specific parameters of various passive and active components. In this work a didactic thermal test system is presented and its use for laboratory practicals in the studies of Industrial Technical Engineering is discussed.

Shape optimization of shell roofs subjected to strong wind is camed out to mimmize the maximum vertical displacement. The three dimensional (3D) fluid flow analysis is performed to obtain highly precise dynamic wind load. To reduce the large computational cost of the 3D analysis, the multignd method is employed to solve the pressure Poisson equation. The objective function of the optimization problem is expected to have strong nonlineanty. Employing Response Surface Model (RSM), the objective function is approximated as a smooth function so that computational cost of the optimization is reduced. Analyses for several experimental points are required to generate RSM. It is not practical to perform 3D analyses for all experimental points due to huge computational cost. Vanable Complexity Model (VCM) is useful for generating RSM. VCM is the method combining a high-fidelity model and a low-fidelity model. As the method of generating RSM, two kinds of methods are employed;(1) VCM (2) 3D analyses for all the experimental points. Optimized shapes are obtained by both methods. Although the value of the objective function of (1) is slightly larger than that of (2), the computation for (1) is much faster than that for (2).
Unmanned Aerial Systems (UAS) are slowing becoming efficient platforms that can be applied in scientific/commercial remote sensing applications. UAS may offer interesting benefits in terms of cost, exibility, enduranc...
