Abstract: In this paper, common faults in main components of an industrial twoshaft gas turbine are simulated, and the fault signatures are determined in both part and fullload conditions. As fouling and erosion are the most important ...

Abstract: In this paper, a new approach is presented for the graybox identification of Wiener models (WM); and to evaluate the performance of the proposed method, it is used to estimate the dynamic behavior of a twoshaft industrial ...

Abstract: The goal of this work is to monitor the laser powder bed fusion (LPBF) process using an array of sensors so that a record may be made of those temporal and spatial build locations where there is a high probability of defect ...

Abstract: This paper presents the metaheuristic design and optimization of fuzzybased gas turbine engine (GTE) fuel flow controller by means of a hybrid invasive weed optimization/particle swarm optimization (IWO/PSO) algorithm as ...

Abstract: This paper is devoted to present a theorem on a new property of noninvasive control methods applied to stabilize unstable periodic orbits (UPOs). This property is related to the optimal energy consumption of the controller ...

Abstract: In this work, a rapid and low-cost accelerated reliability test methodology which was designed to simulate mechanical stresses induced in flip–chip bonded devices during the thermal cycling reliability test under isothermal ...

Abstract: The goal of this work is to detect the onset of material cross-contamination in laser powder bed fusion (L-PBF) additive manufacturing (AM) process using data from in situ sensors. Material cross-contamination refers to ...

Abstract: The goal of this work is to understand the effect of process conditions on lack of fusion porosity in parts made using laser powder bed fusion (LPBF) additive manufacturing (AM) process, and subsequently, to detect the ...
