in recent years, significant research efforts have been devoted to the optimal planning of power systems. substation expansion planning (sep) as a sub-system of power system planning consists of finding the most economical solution with the optimal location and size of future substations and/or feeders to meet the future demand. the large number of design variables, and combination of discrete ...

in this paper, the problem of layout optimization for x-bracing of steel frames is studied using the ant system (as). a new design method is employed to share the gravity and the lateral loads between the main frame and the bracings according to the requirements of the ibc2006 code. an algorithm is developed which is called optimum steel designer (osd). an optimization method based on an approx...

In this paper, we use gaifman graph to describe the topological structure of the Quantified Boolean Formulae (QBF), we mainly study the formula family with the Small World (SW) network topology. We analyze the traditional Davis, Putnam, Logemann and Loveland (DPLL) solving algorithm for QBF, then we improve the DPLL algorithm and propose the solving algorithm framework based on Small World Opti...

Large scale databases with high dimensional datasets can be mined and used for making decisions which may be unknown information but effective and will be used in the related fields like bio-informatics, medical, business, etc. Clustering is an unsupervised method that creates group of objects or clusters such that objects in the same group are very similar and objects in different group are ve...

Meta-heuristic algorithms are applied in optimization problems in a variety of fields, including engineering, economics, and computer science. In this paper, seven population-based meta-heuristic algorithms are employed for size and geometry optimization of truss structures. These algorithms consist of the Artificial Bee Colony algorithm, Cyclical Parthenogenesis Algorithm, Cuckoo Search algori...

A growing body of literature recognizes the significance soft power in Qatar's foreign policy. There is, however, limited research on long-term impact that occurs from over-dependency power. The popular rhetoric most expresses Qatar uses its power, often form sports diplomacy, to meet policy objectives. review paper attempts identify what extent 2022 World Cup can be understood perspective, and...

Environmental pollution and emissions, along with the increasing production and distribution of goods, have placed the future of humanity at stake. Today, measures such as the extensive reduction in emissions, especially of CO2 and CO, have been emphasized by most researchers as a solution to the problem of environmental protection. This paper sought to explore production routing pro...

Nature-inspired algorithms (NIAs) have gained a significant popularity in recent years to tackle hard real world problems and solve complex optimization functions whose actual solution does not exist. Many new algorithms have been developed which show their capabilities almost in every aspect, where rapid solutions are needed. A survey of the NIAs that are used to find the optimal digital image...
