the gravitational search algorithm (gsa) is a novel optimization methodbased on the law of gravity and mass interactions. it has good ability to search forthe global optimum, but its searching speed is really slow in the last iterations. sothe hybridization of particle swarm optimization (pso) and gsa can resolve theaforementioned problem. in this paper, a modified pso, which the movement ofpar...

Many planning tasks of autonomous robots can be modeled as partially observable Markov decision process (POMDP) problems. Point-based algorithms are well-known algorithms for solving large-scale POMDP problems. Several leading point-based algorithms eschew some flawed but very useful heuristics to find an -optimal policy. This paper aims at exploiting these avoided heuristics by a simple framew...

HARP-images of each harmonic peak. The phase is distorted due to B0-inhomogeneity, e.g. in the liver. d) (=b+c) B0-map. e) (=bd/2) Peak-combined HARP-image: Phase wraps of B0-map are present, impairing HARP-analysis. f) Unwrapped B0-map. g) (=b-f/2) Peak-combined HARP-image: No phase distortions (wraps aligned with taglines) and no phase-wraps from B0-map. h) Fully unwrapped peak-combined HARPi...

BACKGROUND To investigate whether 2 cardiac troponins [conventional troponin-T(cTnT) and high sensitive troponin-T(hsTnT)] combined with simplified pulmonary embolism severity index (sPESI), or either test alone are useful for predicting 30-day mortality and 6 months adverse outcomes in patients with normotensive pulmonary embolism(PE). METHODS The prospective study included 121 consecutive p...

the present research proposes and optimizes the performance of a novel solar-driven combined cooling, heating, and power (cchp) kalina system for two seasons—winter and summer—based on exergy, exergo-economic, and exergo-environmental concepts applying a non-dominated sort genetic algorithm-ii (nsga-ii) technique. three criteria, i.e. daily exergy efficiency, total product cost rate, and total ...

the decision to buy, sell, design and construct residential apartments is a complex process due to a combination of multiplequalitative and quantitative factors. it thus requires a great deal of costs and time for decision makers in this market. identifying these factors and determining the priority of them are importance for selectingan apartment. the aim of current research is to identify the...

effect of different ratios of sucrose to fruit concentrate (orange and sour cherry), level of cacl2 (0-2%) and storage time (0-90 days) on physicochemical properties of candied apples were investigated using of a combined design. different quality indices such as total sugars content, ascorbic acid, color attribute (chroma) and overall acceptance were modeled and then multiobjective optimizatio...

Listeriosis is one of the CNS inflammatory diseases which is happened majority in the form of sporadic. Listeriosis is ingested with the food. Infection occurrence in an exposed person depends on the number of organisms ingested, the virulence of the organisms strain and the individual condition. It is known that Listeriosis has decisive importance as an infection which the cellular immunodefen...

In this paper, we study the existence of solutions for nonlinear sequential Caputo and Caputo-Hadamard fractional differential equations with three-point boundary conditions by using measure noncompactness combined fixed point theorem M?nch. An example illustrating effectiveness theoretical results is presented.
