BOD is a parameter frequently used to evaluate the water quality on different rivers. The aim of the present study is to investigate applicability of artificial intelligence techniques such as ANFIS (Adapti ve Neuro-Fuzzy Inference System) in water quality BOD prediction for the case study, Mahi river at Khanpur in Thasara Taluka of Kheda District in Gujarat State, India. The proposed technique...

the objective of this research was to conduct a bench scale study of fixed activated sludge treating domestic sewage. two different units employing diffused aeration with plastic and aluminum media were studied in four separate phases. data indicated that the system could produce a high quality effluent without any requirements for sludge recycling through the system. suspended solids concentra...

A study was conducted to assess the performance of anaerobic-aerobic treatment system of a local potato processing industry. The wastewater treatment plant (WWTP) consisted of primary treatment, upflow anaerobic sludge blanket (UASB), activated sludge process (ASP) and secondary clarifier. The study analyzed the physical, chemical and biochemical parameters of the influent (raw sewage) as well ...

Combining the concept of software control with existing legacy network technology promotes new networking services with low capital expenditure. Currently, many testbeds and academic operators provide bandwidth on demand (BoD) services over layers 2 and 3 wide area network. BoD decreases operational expenditures and manual errors. However, administrators must continue to manually configure virt...

The integration of bioinformatics resources worldwide is one of the major concerns of the biological community. We herein established the BOD (Bioinformatics on demand) system to use Grid computing technology to set up a virtual workbench via a web-based platform, to assist researchers performing customized comprehensive bioinformatics work. Users will be able to submit entire search queries an...

In this paper, we consider the mathematical formulation and analysis of an optimal control problem for a nonlinear Dissolve Oxygen(DO)/ Biological Oxygen Demand(BOD) system with logistic growth term. In the BOD/DO system studied by Bermúdez [2] this logistic growth term is not included. We study the existence and uniqueness of solution for the nonlinear system as well as the existence and uniqu...

Bimbo – Ricolino candy manufacturing plant in Mexico City was discharging wastewater with high amount of fats oil and grease and dissolved sugars. Local regulatory agency requested that suspended solids, oil and grease and dissolved BOD be almost completely removed prior to discharge to municipal plant. The available real estate in Mexico City was very limited. A multistep treatment system was ...

The efficiency of constructed wetland to treat weak and medium primary sewage effluent was tested under three rates of sewage inflow and two types of growing plants (i.e., leaf cattail and common reed). The capability of the wetland to remove COD, BOD, TSS, TDS and F. coliform from the primary weak sewage increased with decreasing the rate of the sewage inflow from 12 L/hr. to 6L/hr., with litt...

There are many system proposals for satellitebased broadband communications that promise high capacity and ease of access. Many of these proposals require advanced switching technology and signal processing on-board the satellite(s). One solution is based on a geo-synchronous (GEO) satellite system equipped with on-board processing and on-board switching. An important feature of this system is ...

BACKGROUND AND PURPOSE Intracranial atherosclerotic stroke (ICAS) has various stroke mechanisms, including branch occlusive disease (BOD), subcortical infarcts caused by parent arterial disease occluding the perforator's orifice, and non-BOD, infarcts beyond the subcortical area caused by artery-to-artery embolism. To test whether these 2 types of ICAS had different vascular pathophysiologies, ...
