existed electricity grids deliver produced power to the consumer passing through transmission and distribution grids. according to high losses of these grids in transmission level and inexistence of bilateral interaction for simultaneous information exchange, a concept of smart grids were made by capabilities such as consciously participation of consumers in the smart electricity grids, an amou...

smart home is composed of several controllers with different plants in control. if each controller works independently, without considering the mutual effect of the others in the control process, the whole system could definitely not converge to an optimum desired status and may not ever reach the demanded condition. the function of different controller system may has conflict in some condition...

a solution to the problem of identification and control of smart structures is presented in this paper. smart structures with build-in sensors and actuators can actively and adaptively change their physical geometry and properties. as a particular example, a representative dynamic model of a typical fighter vertical tail, identified as the smart fin, is considered. piezoelectric patches, which ...

the microgrid concept provides attractive solutions for reliability enhancement of power distribution systems. normally, microgrids contain renewable-energy-based distributed generation (dg) units, which their output power varies with different environmental conditions. in addition, load demand usually changes with factors such as hourly and seasonal customer activities. hence, these issues hav...

nowadays, environment-sensitive smart drug delivery systems have found diverse applications in pharmaceutical science and technology. these systems can respond to the environment stimuli such as temperature, pressure, ph, light, electrical and magnetical fields and etc. they can release the proper amount of drug in human body. among these systems, special attention and much research works have ...

reaching an electricity system which is both economically efficient and environmentally friendly is motivating countries to design and execute different types of tou demand response programs. but there are certain deficiencies which prevent these programs to effectively modify the load shape. smart grid as a means could help the electricity system to reach the highest demand side management ...

in this paper smart operation of micro energy hub is presented. energy hub system consists of certain energy hubs and interconnectors that are coordinated by energy hub system operator. an energy hub contains several converters and storages to serve demanded services in most efficient manner from available energy carriers. in this paper, the flexibility of energy delivery point is enhanced u...

Internet of Things (IoT) approach is empowering smart city creativities all over the world. There is no specific tool or criteria for the evaluation of the services offered by the smart city. In this paper, a new Multilayer Fuzzy Inference System (MFIS) is proposed for the assessment of the Planet Factors of smart city (PFSC). The PFSC system is categorized into two levels. The proposed MFIS ba...

in this paper, load and buckling mode of a smart column are presented. the theoretical model is a three-layer piezoelectric composite beam that behaves as an axial actuating mechanism. this actuator consists of an elastic core sandwiched between two piezoelectric active outer layers. the piezoelectric layers are polarized transversely, i.e., the polarization vector is parallel to the applied el...
