Dunia industri otomotive tidak lepas dengan adanya proses pengujian kinerja mesin sebelum dipasang didalam body kendaraan tersebut. Didalam ada faktor stop produksi yang dikarenakan parameter sesuai standar ditetapkan dan dapat merugikan perusahaan, salah satunya suhu udara keluar dari intercooler masuk ke mesin. Pada penelitian ini telah dilakukan optimasi mengganti modifikasi system mendesain...

This paper proposes a new computational scheme for approximating variable-order fractional integral operators by means of finite element scheme. This strategy is extended to approximate the solution of a class of variable-order fractional nonlinear systems with time-delay. Numerical simulations are analyzed in the perspective of the mean absolute error and experimental convergence order. To ill...

The goal of this research is the derivation of method for evaluation of efficiency improvement potential for district heating systems with focus on variable speed centrifugal pump. The effectiveness of the usage of the proportional pressure control is compared with the constant pressure control. This is why, energy calculation analyses have been realized for variable speed centrifugal pumps, an...

Traditional vibration monitoring techniques have found it difficult to determine a set of effective diagnostic features due to the high complexity of the vibration signals originating from the many different impact sources and wide ranges of practical operating conditions. In this paper Principal Component Analysis (PCA) is used for selecting vibration feature and detecting different faults in ...
