This paper presents an adaptive fuzzy control scheme for non-affine nonlinear multi-input multi-output smart structure systems. From an initial fuzzy system with a small number of rules, the self-structuring algorithm can ...
This paper proposes a new level set method for structural shape and topology optimization using a semi-implicit scheme. Structural boundary is represented implicitly as the zero level set of a higher-dimensional scalar ...
A sensitivity analysis method for the equivalent parameter extraction of transient magnetic field problems with internally coupled circuits is presented. In contrast to conventional methods using physical meaning and ...
Previous methods of sensorless vector control of the PMSM operate by indirectly determining the rotor position usually from the back EMF or from saliency detection using HF injection. This paper introduces an entirely new ...
Although Differential Global Positioning System (DGPS) provides positioning information with high precision, when DGPS is unavailable in some situations, stand-alone GPS has to be used in vehicle navigation. The accuracy ...
Evaluating the network reliability is an important topic in the planning, designing, and control of systems. The minimal cut set (MC, an edge set) is one of the major and fundamental tools for evaluating network reliability. ...
Many real-world systems are multistate systems composed of multistate components in which the reliability can be computed in terms of the lower bound points of level d, by formulating in terms of either the d-minimal paths ...
Many real-world systems are multistate systems composed of multistate components in which the reliability can be computed in terms of the lower bound points of level d, called d-MCs. Such systems (electric power, transportation, ...
The problems studied here belong to a class called graph partition. They are combinatorial problems which consist of finding a partition of vertices into components in order to optimise a given measure. A variety of ...
A MP/minimal cutset (MC) is a path/cut set such that if any edge is removed from this path/cut set, then the remaining set is no longer a path/cut set. An intuitive method is proposed to evaluate the reliability in terms ...
In this paper, a modified direct torque control (DTC) for permanent-magnet synchronous machines, which enables important torque- and flux-ripple reduction by using voltage vectors with variable amplitude and angle, is ...
Many real-world systems are multistate systems composed of multistate components in which the reliability can be computed in terms of minimal path (MP) vectors to level d (named d- MPs). Such systems (electric power, ...
The weighted multicommodity multistate unreliable network (WMMUN) is a novel network composed of multistate unreliable components (arcs and nodes) capable of transmitting different types of commodities in which capacity ...
In order to assess a situation and support decision makers' awareness for the situation, this study first proposes a situation assessment model with mathematical description. It then develops a Support Vector Machine based ...
This paper describes a project which addresses the use of a small segmented oscillating water column with three sections. The turbine utilizes cascaded Savonius rotors (one for each section), and this system is developed ...

A transformation technique is presented to minimize soil brightness influences from spectral vegetation indices involving red and near-infrared (NIR) wavelengths. Graphically, the transformation involves a shifting of the ...
In this paper, the recently research results of assembly process's simulation of high-field permanent-magnetic flux source is presented. A 2D vector Jiles-Atherton magnetic hysteresis model is employed in magnetic field ...
Iron nanoparticles are becoming increasingly popular for the treatment of contaminated soil and groundwater; however, their mobility and reactivity in subsurface environments are significantly affected by their tendency ...
