Item Assessment of retention basin volume and outlet capacity in urban stormwater drainage systems with respect to water quality(Indian Academy of Sciences, 2005) Yurdusev M.A.; Kumanlioǧlu A.A.; Soemaz B.The quality of river water or other surface waters is detrimentally affected by the contaminants carried by the rainfall runoff in urban areas. The control of pollution moved by rainfall runoff is achieved by installing outlets and small retention basins in stormwater collection systems, thereby allowing only a certain amount of rainfall water to overflow and leading the remaining to treatment plants. This study analyses the effect of concentration time on surface water pollution caused by rainfall runoff. For this purpose, a linear S-curve is assumed for the flow hydrograph arising from the collection system, based on parameters of rainfall considered and the catchment area. An independent code is developed to analyse such a system and this is applied to an urban area using nine-year single-discrete rainfall records of Izmir Station, Turkey. The system is capable of tackling situations where there is only a basin or a basin with outlet.Item Extending experimental data to investigate phosphogypsume use in light brick by Artificial Neural Networks(2007) Yurdusev M.A.; Kumanlioǧlu A.A.; Abali Y.; Zeybek M.S.; Canpolat F.In this study, usability of wastes produced in phosphoric acid plants in structural brick manufacture has been investigated. A series of experiments for three different material combinations namely original waste plus normal brick clay, washed waste plus normal brick clay and normal brick clay with no additive were carried out to achieve this end. The results have shown that the industrial wastes considered improve the performance of the bricks. However, the results have also shown that further investigations are needed to explore the effects of interim or outer values on the performance of the bricks. To active that end, a neural experimental study is adopted. The outcome of these artificial tests have provided the appropriate values for the waste addition rate, firing speed and firing temperature. © 2007 Taylor & Francis Group, London.Item Using phosphogypsume and boron concentrator wastes in light brick production(2007) Abali Y.; Yurdusev M.A.; Zeybek M.S.; Kumanlioǧlu A.A.In this study, use of wastes produced in phosphoric acid plants and boron concentrators in producing structural brick has been investigated. There are several parameters involved in using these wastes in brick production namely the rate of added waste, firing speed and firing temperature. The performance of these parameters can be measured by several criteria such as natural drying shortening, water absorption and weight loss. Therefore, so many experiments are needed to investigate the effects of these parameters on the bricks produced with these wastes. To this end, around 220 experiments for three different material combinations namely original waste plus normal brick clay, washed waste plus normal brick clay and normal brick clay with no additive were carried out. The results have shown that the industrial wastes produced by phosphoric acid plants can improve the performance of the bricks in terms of drying shortening, weight loss and water absorption. © 2005 Elsevier Ltd.

Firstly, domestic water use forms are analyzed in an attempt to estimate how much water is used by a particular use in total domestic use. Then, the water conservation measures for each water practice are examined and some easy-to-apply measures proposed. Finally, an experimental study was conducted to determine if the domestic water conservation measures proposed were applicable for the city considered. For this purpose, a questionnaire was developed and 200 respondents were asked to fill it in. The respondents were chosen from different people based on education level, financial status and size of the family to represent the society living in the city. Based on the results of the study, it is shown that the measures proposed are quite applicable and around 27% saving is manageable if the proposed measures are publicized adequately and applied effectively. © Springer Science+Business Media, Inc. 2007.Item Neural extension of experimental data to investigate using phosphogypsume in light brick production(2009) Yurdusev M.A.; Kumanlioǧlu A.A.; Abali Y.; Zeybek M.S.In this study, usability of wastes produced in phosphoric acid plants in structural brick manufacture has been investigated. There are several parameters involved in using these wastes in brick production namely the rate of added waste, firing speed and firing temperature. The performance of these parameters can be measured by several criteria such as natural drying shortening, water absorption and weight loss. Therefore, so many experiments are needed to investigate the effects of these parameters on the bricks produced with these wastes. The result of a series of experiments were utilized to achieve this end. The results have shown that the industrial wastes considered improve the performance of the bricks in terms of the criteria mentioned above. However, the results have also shown that further investigations are needed to explore the effects of interim values on the performance of the bricks. To achieve that end, a neural experimental study is adopted. For this purpose, the results of the experiments conducted were used to construct an artificial neural network. The trained and tested network was then used to check the effects of 280 different combinations for each type of material mixtures mentioned. The outcome of these artificial tests have provided the optimal values for the waste addition rate, firing speed and firing temperature based on the four criteria mentioned previously. © 2008 Elsevier Ltd.
