Abstract Simultaneously optimizing the estimation of centroid and separation two incoherent optical point sources is constrained by a tradeoff relation determined an incompatibility coefficient. At Rayleigh distance, coefficient vanishes thus no longer restricts simultaneous optimization measurement for joint estimation. We construct such optimal elaborated analysis on operator algebra symmetri...

Wireless Sensor Networks (WSN) typically consist of a large number of densely populated sensor nodes. Due to important advances in integrated circuits and radio technologies, the use of distributed sensor networks is more and more widespread for a variety of applications, such as indoor navigation, environmental monitoring, people and objects tracking, logistics, industrial diagnostics, quality...

The optimal locating of facilities has large effects on economic benefits, providing satisfactory service and levels of customer satisfaction. One of the new topics discussed in location problems is hub location and hub facilities are subject to unpredictable disruptions. This paper proposes a nonlinear integer model for reliable single allocation hub location problem that considers backup hub,...

Smart distribution networks (SDNs) plays a significant role in future power networks. Accordingly, the optimal scheduling of such networks, which include planning of consumers and production sections, inconsiderably concerned in recent research studies. In this paper, the optimal planning of energy and reserve of SDNs has been studied. Technical constraints of distribution network and power gen...

Technical structures with a parallelepiped form are frequently used in various areas of industry. For example, as fluid containers, ice and minerals piles, underground surface storages cooling chambers. A task determining the optimum dimensions structure to minimize energy expenses support normative temperature arises. The minimum area at given volume is accepted criterion optimality. problem u...

To be competitive, an industrial robot picking fruits must be able to perform this task in an amount of time which compares to that needed by humans. Because the location of a fruit changes due to the picking of others, the determination of their location has to be performed on-line and also the associated path planning for the robot. This poses two major problems in the development of fruit-pi...

Success in fast cycle industries (e.g. consumer electronics) can depend both on rapid model replacement and on model longevity. Although Sony was as fast as any of its chief competitors in getting new models to market, an important explanation for the wide variety of models offered by the firm is the greater longevity of its key models. This finding adds an important insight to the conventional...

Stochastic local search (SLS) is the dominant paradigm for incomplete SAT and MAXSAT solvers. Early studies on small 3SAT instances found that the use of “best improving” moves did not improve search compared to using an arbitrary “first improving” move. Yet SLS algorithms continue to use best improving moves. We revisit this issue by studying very large random and industrial MAXSAT problems. B...
