The Mathematical Model

This software is aimed at providing engineering design personnel who are engaged in marine gas turbine power system design and performance optimization with a software platform for concentrated design and management. First, the mathematical model of the sub-shaft gas turbine was established using volume inertia and rotor inertia method. And then the relative non-linear simulation module base of all components was built based on MATLAB/Simulink. Second, in order to develop this extensible simulation software for the study on the marine gas turbine overall performance, a human-computer interface was cultivated too based on MATLAB/GUI. This software provides the functions of analyzing dynamic performance of the marine gas turbine power system in both on-design and off-design operating conditions. It offers engineering design personnel an extensible and useful GUI platform in gas turbine system design and performance optimization.

Using Data

We investigate two determinants of two choices in the control system of divisionalized firms, namely decentralization and use of performance measures. The two determinants are those identified in the literature as important to control system design: (1) information asymmetries between corporate and divisional managers and (2) division interdependencies. We treat decentralization and performance measurement choices as endogenous variables and examine the interrelation among these choices using a simultaneous equation model. Using data from 78 divisions, our results indicate that decentralization is positively related to the level of information asymmetries and negatively to intrafirm interdependencies, while the use of performance measures is affected by the level of interdependencies among divisions within the firm, but not by information asymmetries. We find some evidence that decentralization choice and use of performance measures are complementary.

Abstract In this paper, we design the simultaneous wireless information and power transfer (SWIPT) protocol for massive multi-input multi-output (mMIMO) system with non-linear energy-harvesting (EH) terminals. In this system, the base station (BS) serves a set of uplink fixed half-duplex (HD) terminals with non-linear energy harvester. Considering the non-linearity of practical energy-harvesting circuits, we adopt the realistic non-linear EH model rather than the idealistic linear EH model. The proposed SWIPT protocol can be divided into two phases. The first phase is designed for terminals EH and downlink training. A beam domain energy beamforming method is employed for the wireless power transmission. In the second phase, the BS forms the two-layer receive beamformers for the reception of signals transmitted by terminals. In order to improve the spectral efficiency (SE) of the system, the BS transmit power- and time-switching ratios are optimized. Simulation results show the superiority of the proposed beam-domain SWIPT protocol on SE performance compared with the conventional mMIMO SWIPT protocols.
