In this letter, we introduce quality of service-aware beamformer design for full-duplex wireless-powered relay with self-energy recycling. In the first phase of communication, the information signal is transmitted from the source to the relay. In the second phase, the relay forwards this signal using beamforming while it harvests energy via self recycling and from the source. The aim is to satisfy the signal-to-noise ratio requirement of the destination with minimum transmission power from the relay's own battery. A closed-form solution for the optimum relay beamformer is derived and the feasibility conditions are obtained. The effects of different system parameters on the relay's performance are discussed in the simulation results.

Optimum Discrete Max-Min Style Broadcast Beamforming Design Demir, Özlem Tuğfe; Tuncer, Temel Engin (2014-04-25) In this paper, max-mm style transmit beamformer design for single group multicast (broadcast) scenario is considered. The phase and amplitude values of beamformer vector coefficients are selected from finite discrete sets. With the help of integer variables, original optimization problem is converted to a linear form appropriate for mixed integer linear programming. The solution is always feasible as long as the total power is above a certain value. Branch and cut strategy guarantees the optimum solution. P...
Optimum design of steel lattice transmission line towers using simulated annealing and PLS-TOWER Tort, Cenk; Sahin, Serkan; Hasançebi, Oğuzhan (2017-01-15) This paper presents a new optimization tool for automated design of steel lattice transmission line towers in real-world engineering practice. This tool has been developed by integrating the simulated annealing (SA) optimization algorithm into the commercial PLS-TOWER software to optimize steel lattice towers for minimum weight according to ASCE 10-97 design specification using both size and layout design variables. In this context, a novel two-phase SA algorithm is specifically developed and compared with ...
Pseudo-steady state inflow performance relationship of reservoirs undergoing multiphase flow and different wellbore conditions Al-Rbeawi, Salam (Elsevier BV, 2019-08-01) This paper introduces an integrated approach for the inflow performance relationship of reservoirs that undergo multiphase flow conditions and drained by vertical wells with different wellbore conditions. The main objective is eliminating uncertainties that govern predicting reservoir performance by assuming single phase flow in the porous media. The proposed approach includes developing several models for multiphase flow conditions using PVT data and relative permeability curves. These models are assembled...
Design optimization of a mixed-flow compressor impeller for a small turbojet engine Cevik, Mert; Uzol, Oğuz (2011-01-01) Purpose - This paper aims to present the results of a design optimization study for the impeller of a small mixed-flow compressor. The objective of the optimization is to obtain an impeller geometry that could minimize a cost function based on the specific thrust and the thrust specific fuel consumption of a small turbojet engine.
ACCLOUD-MAN - Power efficient resource allocation for heterogeneous clouds ACCLOUD-MAN - Heterojen bulutlarda güç etkin kaynak atamasi Ekici, Nazim Umut; Schmidt, Klaus Werner; Yazar, Alper; Schmidt, Şenan Ece (2019-04-01) In this paper we propose ACCLOUD-MAN, a novel resource manager for heterogeneous cloud data centers. In heterogeneous clouds a user request can be satisfied with more than one physical resource alternative. Resource manager must decide which resource alternative will be chosen, along with the decision of the server the request will be assigned to. ACCLOUD-MAN's resource management objective is to reduce the power consumption of the cloud. Manager is modeled as an Integer Linear Problem and is implemented on...
