in this paper the effect of site conditions, which are altitude, temperature and relative humidity and also heat dissipation capacity are investigated on the optimized design of natural draft dry cooling towers with specific kind of heat exchangers, known as forgo t60 type. a genetic algorithm program has been developed for optimized design of these cooling towers. objective function includes b...

a methodology is presented in this paper to find optimal location and dosage of chlorine injection in water distribution networks. the objective is to minimize the chlorine consumption while keeping the residual chlorine at each node within the standard range. unfortunately because of wrong water quality management in water distribution networks in many parts of the world, many problems such as...

In this study the suitability of Raman spectroscopy for the determination of carbon nanotube mediated toxicity on human alveolar carcinoma epithelial cells (A549) is explored. The exposure of this cell line represents the primary pathway of exposure in humans, that of inhalation. Peak ratio analysis demonstrates a dose-dependent response which correlates to previous toxicological studies. Princ...

Seawater desalination water intake site selection has an important impact on the investment, production cost, stable operation, and safety of seawater plants. Site is affected by many factors, such as natural geography, ecological environment, social economy coastal zones; some constraints can be directly identified unsuitable areas for these construction projects. For shallow method desalinati...

Dipper throated optimization (DTO) algorithm is a novel with very efficient metaheuristic inspired by the dipper bird. DTO has its unique hunting technique performing rapid bowing movements. To show efficiency of proposed algorithm, tested and compared to algorithms Particle Swarm Optimization (PSO), Whale Algorithm (WOA), Grey Wolf Optimizer (GWO), Genetic (GA) based on seven unimodal benchmar...

The urban waste transfer network plays an important role in life, and the site selection route planning involved are not only research issues field of logistics systems, but also closely related to social people’s livelihood. In this paper, starting from overview problem, a two-layer model optimization is constructed, genetic algorithm improved ant colony used study them respectively.

Based on the background of Gutian country-level green-way planning project, this essay carries out suitability evaluation and empirical study of green-way network selection based on GIS.The main study contents include: According to the green-way network selection principles and analysis of basic construction conditions,taking overlay analysis of GIS quantitative suitability , and putting forwar...

Increasing economy’s resistance against the menace of sanctions, various risks, shocks, and internal and external threats are one of the main national policies which can be implemented through bank investments. Investment project selection is a complex and multi-criteria decision-making process that is influenced by multiple and often some conflicting objectives. This paper studies portfolio inve...
