Comparision of ant colony optimization and genetic algorithm models for identifying the relation between flow discharge and suspended sediment load (Gorgan River - Iran)

Correct estimation of sediment volume carried by a river is very important for many water resources projects. The prediction of river sediment load also constitutes an important issue in hydraulic and river engineering. Conceptual models based on artificial intelligence models, namely, ant colony optimization (ACO) and genetic algorithm (GA) are now being used more frequently to solve optimization problems. Hence, the...

Evaluation of herd structure of white Fulani cattle holdings in Zaria, Nigeria

A survey of 20 Fulani households in Zaria and environs revealed that the maximum and minimum herd size of Fulani cattle holdings in Zaria is 69 and 16, respectively, with the mean herd size of 41.5. The cattle stock composition showed a gender imbalance, with a preponderance of female stock than males. On the average, female animals constituted 60 to 75% in each herd type. The young animals contributed about 50% of the...

Adaptive automata model for learning opponent behavior based on genetic algorithms

The purpose of this research is to study how genetic algorithms (GA's) are applied in the field of Game Theory. GA's are effective approaches for machine learning and optimization problems. In this work, genetic algorithm is utilized to determine the behavior of an opponent in Prisoners’ Dilemma. The opponent behavior will be modeled by means of adaptive automaton. The basic problem of this study is the...

Mucocutaneous mycoses in acquired immune deficiency syndrome (AIDS) patients hospitalised in a tertiary healthcare centre in the state of Amazonas-Brazil

Several studies have been performed in which the severity of human immunodeficiency virus (HIV) infection is correlated with skin manifestations. The state of Amazonas-Brazil has a high incidence of HIV infection (2008, 26/100.000 hab), and this state is located in the tropics, a climate that promotes the development of mycoses; however, few studies have been published in the literature that discuss the...

Investigation of the hygienic situation of kitchens, bathrooms and toilets in the traditional residential architecture

This study investigated the hygiene state of kitchens, bathrooms and toilets and how they are used in the traditional houses (their characteristics, the changes in their uses and the extent of these changes). The study also attempted to find the principles and criterions on which the arrangements that are the products of accumulated experiences were based in the spaces or systems. Furthermore, the study investigated how...

Vermicomposting potential and plant nutrient contents in rice straw vermicast of Perionyx excavatus and Eudrilus eugeniae

Vermicomposting is proven to be an effective way for nutrient cycling, converting large quantities of organic waste into value added product (vermicast). In order to harness the potential of earthworms in vermicomposting, selection of earthworm species that are able to consume large quantity of waste, and moreover, produce vermicast with high nutrient content is important. This experiment was carried out to compare the...

Use of urea-formaldehyde in the production of diatomite-based lightweight building components

This research, being the first research in the literature, investigates use of urea-formaldehyde, a widely used polymer, as a binder in producing diatomite-based lightweight building elements. Urea-formaldehyde and ground diatomite of granular size under 500 microns were blended at ratios of 10, 15, 20, 25, 30, 35, 40, 45, and 50% by volume and fired at temperatures ranging from 80 to 140°C  to obtain test...

Potential of neem leaf-empty fruit bunch-based vermicompost as biofertiliser-cum-biopesticide: Chemical properties, humic acid content and enzymes (protease and phosphatase) activity in vermicompost (Part I)

The palm oil industry generates empty fruit bunch (EFB) in large quantities, which need to be optimally exploited to obtain maximum benefits from their uses. Vermicomposting of EFB with neem leaves is of great interest, as the end product might function as biofertiliser as well as biopesticide. Therefore, vermicomposting of different ratios of EFB and neem leaves using Eudrilus eugeniae as a composting agent was...

Brachyuran crabs (Crustacea: Decapoda) in the Suez Canal, Egypt, and their associated epifauna

The Suez Canal is the main connecting link between the Red Sea and the Mediterranean. On its route from the Red Sea in the south to the Mediterranean in the north, it crosses different lakes which represent different habitats, and in some cases, hinder the migration of the faunal community from one sea to the other. Ten Brachyuran species belonging to ten genera and eight families were recorded in the canal water, all...
