Gametophytic phase of Doryopteris triphylla (Pteridaceae, Polypodiopsida)

Gametophytes of the Pteridaceae are moderately well known but there is still a quite large set of species to describe. Among these is Doryopteris triphylla, a member of the cheilanthoid clade (subgroup hemionitids). The main objective of this work is to describe the gametophyte of D. triphylla. In vitro cultures were prepared with spores coming from various sporophytes of different locations. I...

A new Stochastic Hybrid Technique for DER Problem

This paper presents a new Hybrid Particle Swarm optimization with Time Varying Acceleration Coefficients (HPSOTVAC) and Bacteria Foraging Algorithm (BFA) namely (PSOTVAC/BFA) base fuzzy stochastic long term approach for determining optimum location and size of Distributed Energy Resources (DERs). The Monte Carlo simulation method is used to model the uncertainties associated with long-term load...

A new hybrid conjugate gradient algorithm for unconstrained optimization

In this paper, a new hybrid conjugate gradient algorithm is proposed for solving unconstrained optimization problems. This new method can generate sufficient descent directions unrelated to any line search. Moreover, the global convergence of the proposed method is proved under the Wolfe line search. Numerical experiments are also presented to show the efficiency of the proposed algorithm, espe...

A New Hybrid Brushless DC Motor/Generator without Permanent Magnet

The Brushless DC (BLDC) motor is a simple robust machine which has found application over a wide power and speed of ranges in different shapes and geometry. This paper briefly reviews the fundamentals behind the motor and also the different types of BLDC motors with different geometries and then presents a new configuration for BLDC motor/generator, which does not use a permanent magnet in the ...
