Abstract. In this paper, we propose to study a generalized form of the exponential power distribution which contains others in the literature as special cases. This unifying exponential power distribution is characterized by a parameter ω and a function h(ω) which regulates the tail behavior of the distribution, thus making it more flexible and suitable for modeling than the usual normal di...

Beam combining techniques have become an important tool in design of high-power highbrightness laser systems [1]. Maximum power that can be obtained from single high-power amplifiers is usually limited by thermal distortion of active medium and beam quality degradation in solid-state lasers or non-linear effects and active fiber damage in fiber lasers. Beam combining offers an alternative solut...

This letter describes the use of a power-optimized cascode configuration for obtaining maximum output power at millimeter-wave (mm-wave) frequencies for a two-way combined power amplifier (PA). The PA has been fabricated in a high-speed InP double heterojunction bipolar transistor technology and has a total active emitter area of 68.4 lm2. The experimental results demonstrate a small signal gai...

This paper presents an analysis of a Curzon and Alhborn thermal engine model where both internal irreversibilities and non-instantaneous adiabatic branches are considered, operating with maximum ecological function and maximum power output regimes. Its thermodynamic properties are shown, and an analysis of its local dynamic stability is performed. The results derived are compared throughout the...

maximum power point tracking controller is essential to obtain the maximum power from a solar array in the photovoltaic systems as the pv power module varies with the temperature and solar irradiation. in this paper, several methods for the mppt of the pv systems are discussed and it can to be used as a helpful reference for the upcoming mppt user in the pv applications.

in the most described maximum power point tracking (mppt) methods in the literatures, the optimal operation point of the photovoltaic (pv) systems is estimated by linear approximations. however, these approximations can lead to less optimal operating conditions and significantly reduce the performances of the pv systems. this paper proposes a new approach to determine the maximum power point (m...

Proper location of DGs in power systems is important for obtaining their maximum potential benefits. This paper deals with DG for minimizing active power loss and D-statcom for reactive power loss minimization is considered. The proper siting of DG and D-statcom is a recently developed combination with the aim of reducing line loss in a radial distribution system. Loss Sensitivity Factor (LSF) ...

Sample-size planning historically has been approached from a power analytic perspective in order to have some reasonable probability of correctly rejecting the null hypothesis. Another approach that is not as well-known is one that emphasizes accuracy in parameter estimation (AIPE). From the AIPE perspective, sample size is chosen such that the expected width of a confidence interval will be su...
