This papers considers the problem of nite-state power control for minimizing the bit-error-rate of uncoded modulation systems over fading channels. Finite-state power control is deened as a power control policy that employs a nite number of distinct power levels, each over a diier-ent interval of the fade depth. We develop an algorithm that determines the optimal nite-state power control and pr...

The paper highlights the urgency of utilizing and promoting use of non conventional sources, particularly the wind and solar energy, so as to control the environmental pollution, such as ozone layer depletion, deforestation, loss of biodiversity, global warming etc. As a case study, the various performance factors of a 10 kW hybrid (wind and solar) power plant, which is having 60:40 power gener...

In this paper, a novel algorithm for the load flow analysis problem in an islanded microgrid is proposed. The problem is modeled without any slack bus by considering the steady state frequency as one of the load flow variables. To model different control modes of DGs, such as droop, PV and PQ, in an islanded microgrid, a new formula for load flow equations is proposed. A hybrid optimization alg...

The aim of this thesis work was to design a power amplifier for WiMAX applications at 3.5GHz based on cheap Si-LDMOS technology and to analyze the behavior of the design regarding nonlinear distortions and memory effects. A MW6S004NT1 Si-LDMOS RF high power transistor, from Freescale, with an ADS MET model was used in the process. This transistor is specified for Class A-AB base station applica...

This study proposes a power management strategy (PMS) that can efficiently and accurately address the nonlinear dynamics of ship systems for all-electric ships (AESs). The design PMS be considered naturally in model predictive control framework. However, error caused by mismatch is challenge physical system implementation. proposed based on complex system-level ensures minimum mismatch. In addi...

The frequency dynamics of gain-switched singlemode semiconductor lasers subject to optical injection is investigated. The requirements for low time jitter and reduced frequency chirp operation are studied as a function of the frequency mismatch between the master and slave lasers. Suppression of the power overshoot, typical during gain-switched operation, can be achieved for selected frequency ...

We propose monolithic diamond cavities that can be used to convert color-center Fock-state single photons from emission wavelengths to telecommunication bands. We present a detailed theoretical description of the conversion process, analyzing important practical concerns such as nonlinear phase shifts and frequency mismatch. Our analysis predicts sustainable power requirements (≲ 1 W) for a chi...
