This paper presents an approach to the reconfiguration of radial distribution networks, for both loss reduction and service restoration, using the same metaheuristic tool: the simulated annealing algorithm. Besides the main objective of each problem (minimizing losses or load not supplied) minimization of the total number of switching device operations is also included as a possible criterion. ...

In order to produce an accurate depth migration of a seismic line, one needs an accurate velocity model. This model should reflect the lithology and lithostatic load that the rocks have experienced through burial and deformation. If we understand the geometry of these rocks, and their behaviour upon deformation, we can produce a more accurate velocity model. Performing palinspastic restoration ...

Emergency response operations in electric distribution systems involve a host of decision-making problems at the reliability, performance monitoring and evaluation, and contingency planning levels. Those operations include fault diagnosis, fault location, fault isolation, restoration, and repair. As the first of a two-part survey, this paper reviews optimization models and solution methodologie...

Direct composites in posterior teeth are a part of the standard therapy spectrum in modern dentistry. The excellent performance of this form of restoration in the masticatory load-bearing posterior region has now been demonstrated in numerous clinical studies. The procedure is usually carried out in an elaborate layering technique. Aside from the possibilities that highly aesthetic composites o...

This paper presents a method for assessing the voltage and reactive power control impact on the reliability indices of distribution networks. It has been achieved by including network constraints (voltage drop and feeder loading) in the predictive reliability model. The analytical method has been used to evaluate the reliability indices. The proposed method has been tested and validated, using ...

introduction: this in vitro study evaluated the influence of composite thickness (with or without fiber reinforcement) on fracture resistance of direct restorations in endodontically treated teeth. methods and materials: fifty-six intact human premolars were chosen and randomly divided into four groups ( n =14). after preparation of a mesio-occluso-distal (mod) cavities and cusp reduction, the ...

Dental implants for insertion from the lateral aspects of the jaw bone have been described repeatedly, since 1972. Long term results have been reported. Due to their design, BOI-Implants (basal osseointegration) can be installed even in those cases, where the vertical bone supply is reduced. This applies to the distal areas of the maxilla and the mandible. Furthermore, BOI-implants allow immedi...

Abstract— HVDC power transmission is coming up with merits to replace the EHV-AC systems. The controller inverter operation can successfully regulate the power in HVDC link leading to fulfillment of power demand in A.C. networks caused by sudden rise in loading. Since overloading and unloading both lead to the departure of operating frequency below or above normal, its control for normalization...

Microgrids are resources to restore critical loads after a natural disaster, enhancing the resiliency of a distribution network. To deal with stochastic power generated by intermittent energy resources within microgrids, such as wind turbines (WTs) and photovoltaics (PVs), most existing methods require forecast information. However, some microgrids may not be equipped with power forecasting too...

Fast and accurate ridge detection in fingerprints is essential to each AFIS (Automatic Fingerprint Identification System). Smudged furrows and cut ridges in the image of a finger print are major problems in any AFIS. This paper investigates a new online ridge detection method that reduces the complexity and costs associated with the fingerprint identification procedure. The noise in fingerprint...
