This study evaluated the efficiency of electrocoagulation in removing chemical oxygen demand (COD), turbidity, and apparent color from incineration effluent generated a gas cleaning system (GCS). Modeling optimization variables electric current (I), hydraulic retention time (HRT), electrode distance (ED) were also performed batch reactor using iron electrodes. A 23 rotatable central composite d...

The covid pandemic points out inconsistencies and to improve in the organization of healthcare logistics. Indeed, dangerousness propagation process virus imply increase health security (patient personal health). In this context, logistics flows require a new safety improving hospital performance. purpose paper consists optimizing by solving problems associated internal such as reduction wasting...

The Internet of Things (IoT) is a network that connects large number items. Each thing uses sensors to create and gather data from its surroundings then sends other objects or central database through channel. Keeping transforming this created one the most difficult tasks in IoT today, it top worries all enterprises deploy technology. Sensing equipment together with communication, storing, disp...

In this paper, we introduce a new aggregate air traffic flow management model. Our integer programming model uses as a starting point the model recently introduced by Bertsimas, Lulli and Odoni. It employs a new set of more general airspace constructs that allow both more complex airspace elements to be represented as well as more aggregate-level modeling. We provide experimental results that i...

background: the family physician plan has recently been implemented in three provinces of iran on a pilot basis and is going to be implemented throughout iran in the future. through a qualitative design, this study aims to determine probable implementation challenges of family physician plan in kerman. methods: this study was conducted in kerman in 2013. data were collected through interviews w...

A Human-In-The-Loop air traffic control simulation investigated the impact of uncertainties in trajectory predictions on NextGen Trajectory-Based Operations concepts, seeking to understand when the automation would become unacceptable to controllers or when performance targets could no longer be met. Retired air traffic controllers staffed two en route transition sectors, delivering arrival tra...
