Recently, an increasing number of multi-MW (1MW and up) wind generation systems are being developed and variable speed-variable pitch (VS-VP) control technology is usually adopted to improve the fast response speed and obtain the optimal energy, which ...

Attention is focused on continuous-space shift-invariant systems with continuous system maps and inputs and outputs that are elements of L_∞ (IR^d). It is shown that infinite superposition can fail in this important setting. It is also shown that ...

Various levels and types of noise are responsible for hindering the valuable information obtained through shallow depth geophysical exploration of archaeological sites. Wavelet transform techniques were tested as a method for decomposition of the ...

Machine tools lie at the heart of almost all manufacturing systems, and their performance has a massive influence on both the performance and productivity of systems. In accordance with the development of computer systems, intelligent technologies have ...

In the paper a method for measuring kinematics of sit-to-stand motion using inertial sensors and human body model is presented. The proposed method fuses data from inertial sensors and data from three-segment human body model using Extended Kalman ...

The paper deals with the problem of computing optimal or suboptimal motion for a network of mobile sensors. The use of moving sensors means that for each point of the field under measurement asynchronous discrete time measures are given instead of ...

With low computation time, the grid-based clustering algorithms are efficient clustering algorithms, but the size of the predefined grids and the threshold of the significant cells are seriously influenced their effects. In grid-based clustering system, ...

This paper addresses the problem of simultaneous static output-feedback stabilization of a collection of interval time-delay systems. It is shown that this problem can be converted into a matrix measure assignment problem. Sufficient conditions for ...

This paper illustrates a numerical approach to magnetic field modeling for a squirrel-cage induction motor fed by various voltage sources: i) an ideal sinusoidal source, ii) a PWM voltage- source-inverter (VSI), and iii) a six-step VSI. A two-...

Hybrid power system is one of the kernel technologies of hybrid electric vehicles (HEV). The performance of HEV is greatly determined by the capability of hybrid power system. The hybrid power system has already developed from discrete structure into ...

Most organizations in all sectors of industry, commerce and government are fundamentally dependent on their information systems (IS) and would quickly cease to function should the technology (preferably information technology - IT) that underpins their ...

Intensive use of e-business can provide number of opportunities and actual benefits to companies of all activities and sizes. In general, through the use of web sites companies can create global presence and widen business boundaries. Many organizations ...

We explore the problem of noise-enhanced stability occurring in an asymmetric double well potential when Brownian particles are driven by trichotomous noise and thermal noise in a dynamical regime where inertial effects can safely be neglected. In the ...

The paper reflects the trend of the past years which is based on the diffusion of various traditional approaches and methods to the way of tackling new problems, in this case to the classification. Two components of the computational intelligence are ...

Bordering on important domains - engineering, medicine and informatics, involving not only knowledge regarding the biosystems structure and functionality, but also knowledge and skills from technical and IT systems, the paper presents the results of ...
