Economic load dispatch (ELD) provides significant benefits to the operation of power system. It appears be a complex nonconvex optimization problem subject several equal and unequal constraints. The greedy sine-cosine nonhierarchical gray wolf optimizer (G-SCNHGWO) is introduced in this study solve ELD problems efficiently robustly. sine cosine functions assist search agents grey (GWO) algorith...

let l = u3(9) be the simple projective unitary group in dimension 3 over a eld with 92 elements. in this article, we classify groups with the same order and degree pattern as an almost simple group related to l. since aut(l) = z4 hence almost simple groups related to l are l, l : 2 or l : 4. in fact, we prove that l, l : 2 and l : 4 are od-characterizable.

A facilidade de propagação vegetativa por estacas herbáceas é uma das características almejadas no trabalho seleção porta-enxertos Prunus spp. melhor adaptados às condições edafoclimáticas do Rio Grande Sul. O objetivo presente foi avaliar a viabilidade técnica da 17 seleções pessegueiro [Prunus persica (L.) Batsch] sob câmara nebulização intermitente, adotando-se três cultivares como referênci...

Vortex methods rely principally on a discretization of the continuous two-dimensional time dependent vorticity eld into a large number of vortex \blobs", whose position and strength determine the underlying velocity eld. In this paper, the convergence of the random vortex method (RVM) for a complex ow is studied in function of three discretization parameters. Two of these parameters are related...

Background and Aims Anesthesia for total abdominal hysterectomies is not only concerned with relieving pain during intraoperative period but also during the postoperative period. We compared clonidine and dexmedetomidine as an adjuvant to levobupivacaine for epidural analgesia with respect to onset and duration of sensory block, duration of analgesia, and adverse effects. Materials and Method...

Introduction: Advances in neonatal medicine have led to the early diagnosis and treatment of respiratory diseases, and the recent development of fetal airway surgery. Data on the growth of the trachea and bronchi are not readily available to the anesthesiologist and bronchoscopist in spite of the obvious clinical interest. The aim of this study was to determine the anatomical development of tra...

The equivalence between the Lawrence-Doniach model for films of extreme type-II layered superconductors and a generalization of the back-scattering model for spin-1/2 electrons in one dimension is demonstrated. This fermion analogy is then exploited to obtain an anomalous H ‖ tail for the parallel equilibrium magnetization of the minimal double layer case in the limit of high parallel magnetic ...

Linkage disequilibrium (LD) provides information about positional cloning, linkage, and evolution that cannot be inferred from other evidence, even when a correct sequence and a linkage map based on more than a handful of families become available. We present theory to construct an LD map for which distances are additive and population-specific maps are expected to be approximately proportional...
