Using Telser and Kataoka models of probabilistic-risky mathematical programming, the present research is to determine the optimized pattern of cultivating the agricultural products of Shoshtar region under risky conditions. In order to consider the risk in the mentioned models, time period of agricultural years 1996-1997 till 2004-2005 was taken into account. Results from Telser and Kataoka mod...

Abstract: Co-cultivation of microalgae and microbes for pollutant removal from sewage is considered as an effective wastewater treatment method. The aim of this study is to screen the optimal photoperiod, light intensity and microalgae co-cultivation method for simultaneously removing nutrients in biogas slurry and capturing CO₂ in biogas. The microalgae-fungi pellets are deemed to be a viable ...

To improve recognition results, decisions of multiple classifiers can be combined. We study the performance of combination methods that are variations of the majority vote. A Bayesian formulation and a weighted majority vote (with weights obtained through a genetic algorithm) are implemented, and the combined performances of 7 classifiers on a large set of handwritten numerals are analyzed.

Parallel pattern matching on a mesh-connected array of processors is considered. The problem is to nd all occurrences of a pattern in a text. The input text is a string of n symbols placed in a p n p n mesh, each processor storing one symbol. The pattern is stored similarly in a contiguous portion of the mesh. An algorithm solving the problem in time O(p n) is presented. It applies a novel tech...

A process comprising two-step fed-batch cultivation has been investigated for the production of ectoines using the halophilic bacterium Halomonas boliviensis DSM 15516(T). The first cultivation was performed under optimal conditions for cell growth and resulted in cell mass concentration of about 41 g l(-1) after 24 h of cultivation. During the second cultivation at higher salt concentration, a...

anthropogenic eutrophication conditioned frequent and more pronounced blooms of toxicalgae and cyanobacteria in the fresh and saline aquatic ecosystems all world around. however, bloomingspecies could serve as a possible resource instead of a threat by exploiting them to remediate nutrients. theoptimised use of algae and cyanobacteria may provide the environmental service together with economic...

Вирус чумы плотоядных является высококонтагиозным патогеном, который характеризуется лихорадкой, пневмонией, воспалением слизистых оболочек, лейкопенией и поражением центральной нервной системы,приводящей часто к летальному исходу. К этой болезни восприимчивы все собаки, независимо от породы, норки, песцы, волки, лисицы, тюлени, тигры и.т.д. В последние годы межвидовые инфекции наблюдались у не...
