The capacitated arc routing problem (CARP) is one of the most important routing problems with many applications in real world situations. In some real applications such as urban waste collection and etc., decision makers have to consider more than one objective and investigate the problem under uncertain situations where required edges have demand for more than one type of commodity. So, in thi...

where, in electrical measurement, a transmitter sends a pulse along a coaxial cable and a receiver and oscilloscope monitor the echoes returning back to the input. Optical TDR was first demonstrated by Barnoski and Jensen in 1976 in multi mode fibres [17] and over the years, it has proved to be an invaluable diagnostic tool for use in both multi mode and single mode optical fibre systems to mea...

A compact and simple patch antenna for ultra high frequency band is current demand for RFID tag. By embedding a pair of symmetrical key-shaped slot near the non-radiating edge of the rectangular patch, a new adjacent resonant mode close to the fundamental mode is excited to form a wide half-power impedance bandwidth (Return loss ≥ 3 dB) of 122 MHz to cover the entire frequency range of ultra hi...

In this paper, we present a review of the recent advances in hybrid vehicle powertrain architectural design. The paper begins with a discussion and categorization of the various types of hybrid vehicles. The current leading technology is the one-mode design of the Toyota Hybrid System and the intent of the state-of-the-art architectures is to improve upon the perceived weakness of the one-mode ...

Summary A pseudo‐multi impulse (PMI) is proposed as an extension of the ordinary base‐input multi substituting a long‐duration, long‐period ground motion which can often be simulated by multi‐cycle sine wave (MSW). PMI treated multitude impulsive lateral forces and hardly excites higher‐mode responses elastic multi‐degree‐of‐freedom (MDOF) models because undamped fundamental participation vecto...

For optimization of real-world arch dams, it is unavoidable to consider two or more conflicting objectives. This paper employs two multi-objective differential evolution algorithms (MoDE) in combination of a parallel working MATLAB-APDL code to obtain a set of Pareto solutions for optimal shape of arch dams. Full dam-reservoir interaction subjected to seismic loading is considered. A benchmark ...

In recent years some multi-mode pushover procedures taking into account higher mode effects, have been proposed. The responses of considered modes are combined by the quadratic combination rules, while using the elastic modal combination rules in the inelastic phases is not valid. Here, an optimum weighted mode combination method for nonlinear static analysis is presented. Genetic algorithm is ...

This paper proposes a new adaptive controller for the robust control of a grid-connected multi-DG microgrid (MG) with the main aim of output active power and reactive power regulation as well as busbar voltage regulation of DGs. In addition, this paper proposes a simple systematic method for the dynamic analysis including the shunt and series faults that are assumed to occur in the MG. The pres...
