Thanks to their manufacturing simplicity, robustness, and consolidated design knowledge, external gear pumps are widely adopted in the automotive fields. With purpose of leading procedure these positive displacement machines, within this work, authors integrate a comprehensive tool salient equations for major pump features. The presented is devoted multistage characterized by singular floating ...

The paper presents a new algorithmic approach for multistage stochastic programs which are seen as discrete optimal control problems with a characteristic dynamic structure induced by the scenario tree. To exploit that structure, we propose a highly eecient dynamic programming recursion for the computationally intensive task of KKT systems solution within a primal-dual interior point method. Co...

Multistage membrane distillation (MD) systems can have significantly higher efficiencies than their single stage counterparts. However, multistage MD system design has received limited attention. In this paper, the performance of a multistage vacuum membrane distillation (MSVMD) which is thermodynamically similar to a multi-stage flash distillation (MSF) is evaluated for desalination, brine con...

A device for ejecting several streams based on the flow of a stream in slit gap and designed mixing liquid gaseous media is considered

Decimator is an important sampling device used for multi-rate signal processing in wireless communication systems. In this paper optimized decimator has been presented to improve the implementation complexity. The proposed decimator is implemented using Matlab as standard FIR, Half Band FIR and Nyquist FIR by using the multistage design techniques. The performance of different decimator designs...
