The paper provides information on the construction, development and functioning of a hospital network for detection treatment patients with dangerous infectious diseases in Republic Guinea. With support UC RUSAL assistance Ministry Health Guinea, hospitals have been established to provide medical care suspected COVID-19. Sick persons are admitted from regional all over country. majority hospita...

This paper presents the state of the PV market in Greece, the achievements so far, the current situation and proposals for next years. The PV market environment in terms of new PV development policies is presented, such as netmetering. The net-metering long awaited program framework is expected to regenerate the PV market in Greece, It was finally introduced at the end of 2014 and the program p...

The emerging and improvement of smart grids, net–zero energy buildings, and advanced building energy demand response technologies continuously drive the needs for better building control and operation strategies and building energy simulation testbeds. However, current building operation strategies and simulation testbeds are all developed assuming that buildings do not share energy resources. ...

A Time Interval Petri net (TIPN) is proposed and used to model flight operation. Based on the TIPN model, the flight delay propagation analysis algorithm is provided, which reduces the complexity of flight delay propagation analysis algorithm. Time interval constraints are attached to places and transitions in TIPN model, which could model the flight turnaround time and flight flying period. Me...

Techno-economic analysis of an indirect use of carbon dioxide within the route of glycerolysis of glycerol with urea is investigated. The results show that the net present value of the biodiesel-glycerol carbonate production by glycerolysis is higher than the biodiesel-glycerol carbonate production by direct carboxylationat at the end of the 12-year operation with similar capacities. The stocha...

A new method is proposed to measure software system security. Each component can be characterized by a composite net which combines the features of Finite State Machine and Operation Diagram. A fuzzy number is introduced to this net to represent uncertain elements that might affect the software security, and thus we construct Security Function for each component. The whole system Security Index...

We introduce ranked open nets, a reactive extension of Petri nets which generalises a basic open net model introduced in a previous work by allowing for a refined notion of interface. The interface towards the external environment of a ranked open net is given by a subset of places designated as open and used for composition. Additionally, a bound on the number of connections which are allowed ...

The paper utilizes Petri_like_net structure in developing an intelligent expert control system to achieve optimum grinding by regulating the parameters of the grinding mill. The work establishes an appropriate theoretical background that helps to predict dynamic breakage characteristics of particle size distribution of materials, adequately supported by experimental data. Feed forward neural ne...

This paper presents a mixed integer linear programming formulation for load-side control of electrical energy demand. The formulation utilizes demand prediction to determine if control actions are necessary, and it schedules both shedding and restoration times based on an optimization model that minimizes the net cost of load shedding. Operational constraints are satisfied through the use of mi...
