Transformer and feeder load balancing in a distribution system reduces the risk of overloads due to load changes. The possible out of service area following the occurrence of a fault is also reduced. However, keeping in view the life expectancy of the switches, it is desirable that the number of switching operations is kept to a minimum. A new algorithm for load balancing based on fuzzy set dec...

The multiplication of heavy vehicle axles and road overloads are phenomena that becoming increasingly important on the network WAEMU community. These phenomena, although framed by standards, have an impact durability pavements. In this manuscript it is a question evaluating life under effect traffic these multi-axle vehicles different tolerances observed network. To achieve this, modeling bitum...

Wastewater Treatment Plants that make use of anaerobic processes for sludge digestion often have problems with phosphates and ammonia nitrogen “overloads” returned to biological sewage treatment process together with effluents coming from dewatering of digestion sludge. The high concentrations of phosphates and ammonium nitrogen in supernatant constitute 10 – 20 % of entire load brought to biol...

We study the propagation of cascading failures in complex supply networks with a focus on nonlocal effects occurring far away from the initial failure. It is shown that a high clustering and a small average path length of a network generally suppress nonlocal overloads. These properties are typical for many real-world networks, often called small-world networks, such that cascades propagate mos...

Supply and transport networks support much of our technical infrastructure as well as many biological processes. Their reliable function is thus essential for all aspects of life. Transport processes involving quantities beyond the pure loads exhibit alternative collective dynamical options compared to processes exclusively characterized by loads. Here we analyze the stability and bifurcations ...

Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiological syndrome characterized by headache, confusion, seizures, and cortical visual loss, as well as subcortical edema without infarction on neuroimaging. We report a 56-year-old woman who developed typical manifestations of PRES, 6 days after blood transfusion for severe anemia. Acute volume overloads by transfusion may exce...
