Multivariable regression and artificial neural network procedures were used to modeling of the input power and gas holdup of flotation. The stepwise nonlinear equations have shown greater accuracy than linear ones where they can predict input power, and gas holdup with the correlation coefficients of 0.79 thereby 0.51 in the linear, and R2=0.88 versus 0.52 in the non linear, respectively. ...

institutional synergy in urban management, as a collective feature is the byproduct of inter and intra institutional activities of urban organizations. it is consider gregarious action and as managerial phenomenon with feature of trust, participation. cooperation engagement, facilitation, mutual recognition and the network. this article scrutiny the capacity of inters intuitional synergy in urb...

Urban areas are responsible for consuming up to 80% of the energy produced worldwide, mainly as a result of human activities. Due to the constantly increasing world population and the shift of this population into cities, over 60% of the world population is projected to reside in urban areas by 2030 and the corresponding increase in human activities will lead to a tremendous increase in energy ...

We simulated a sensor network that detects and tracks the release of harmful airborne contaminants in an urban environment. The simulation determines sensor placement in that environment. The effort required integration of models from computational fluid dynamics (CFDs), combinatorial optimization, and population mobility dynamics. These CFD models, coupled with population mobility models, faci...

URBAN computing is a process of acquisition, integration, and analysis of big and heterogeneous data generated by a diversity of sources in urban spaces, such as sensors, devices, vehicles, buildings, and human, to tackle the major issues that cities face, e.g., air pollution, increased energy consumption and traffic congestion. Urban computing connects unobtrusive and ubiquitous sensing techno...

Worldwide, cities are faced with the challenge of designing and implementing the transition to a state in which their greenhouse gas emissions are drastically reduced and they are well adapted to the impacts of climate change. There is increasing understanding of the synergies and conflicts in the objectives of mitigation and adaptation. These interactions are no more vivid than in urban areas,...
