The law of homologous series in variation has important significance for disclosing the potential hereditary variability plants. use studies cucurbit cropcollections, hybrid populations, mutants, and breeding lines made it possible to discover valuable previously unknown forms watermelon, muskmelon different squash species their practical breeding. For example, these are bushy short vine cultiv...

evolutionary algorithms are some of the most crucial random approaches tosolve the problems, but sometimes generate low quality solutions. on the otherhand, learning automata are adaptive decision-making devices, operating onunknown random environments, so it seems that if evolutionary and learningautomaton based algorithms are operated simultaneously, the quality of results willincrease sharpl...

determining the optimal location of wells with the aid of an automated search algorithm is a significant and difficult step in the reservoir development process. it is a computationally intensive task due to the large number of simulation runs required. therefore,the key issue to such automatic optimization is development of algorithms that can find acceptable solutions with a minimum number of...

Due to the high levels of pollution load produced in leather industry, many studies are being conducted replace most hazardous chemicals used. One options is use enzymes which biodegradable and considered environmentally friendly. Hides skins contain non-collagenous substances that require specific remove. The aim study was evaluate effectiveness different enzyme formulations unhairing process ...

microgrids are small-scale, low voltage (lv) power networks which employ renewable distribution energy resources (ders) with power electronic interfaces (peis). microgrids as single controlled units and active distribution networks require flexible control systems to ensure reliable and secure operation in different modes. these various operations of microgrid cause variations in voltage and fr...

INTRODUCTION The matrilins are a family of four non-collagenous extracellular matrix (ECM) proteins which are important regulators of chondrocyte proliferation and differentiation. During development, matrilin-1 (MATN1) and matrilin-3 (MATN3) are expressed in cartilage and/or bone, while matrilin-2 and matrilin-4 have a broader tissue distribution. Mutations in human MATN3 result in a variety o...

we present an improved implementation of the wagner-whitin algorithm for economic lot-sizing problems based on the planning-horizon theorem and the economic- part-period concept. the proposed method of this paper reduces the burden of the computations significantly in two different cases. we first assume there is no backlogging and inventory holding and set-up costs are fixed. the second model ...

clustering is a widespread data analysis and data mining technique in many fields of study such as engineering, medicine, biology and the like. the aim of clustering is to collect data points. in this paper, a cultural algorithm (ca) is presented to optimize partition with n objects into k clusters. the ca is one of the effective methods for searching into the problem space in order to find a n...

optimization of cutting conditions is a non-linear optimization with constraint and it is very important to the increase of productivity and the reduction of costs. in recent years, several evolutionary and meta-heuristic optimization algorithms were introduced. the cuckoo optimization algorithm (coa) is one of several recent and powerful meta-heuristics which is inspired by the cuckoos and the...
