In this paper, the satellite intermodulation is evaluated in frequency domain, for N-carrier input. Fourier transform is applied to avoid large equations where the number of carriers is quite low. The algorithm is probed with well-known series for ...

In this paper the torque ripple in the 3-phase asymmetrical switched reluctance motor (SRM) drives is considered. Analyzed asymmetrical SRMs have the same geometry as the symmetrical one, but they have an unequal number of turns per phases. The optimal ...

This paper is a presentation of frequency response calculation of switched circuits in Spice program. Evaluated methods are based on transient analysis of circuits followed by Fourier transformation of the computed time response. Three types of circuit ...

The standard data envelopment analysis (DEA) method requires that the values for all inputs and outputs are known exactly. However, this assumption may not be always valid. For example, some outputs and inputs may be only known as in forms of interval ...

In this work the problem of modelling and identification of an activated sludge depollution bioprocess is focused. This bioprocess is in fact an aerobic fermentation process that is carried out in a recycle bioreactor. A nonlinear dynamical model is ...

The authors report a research about environment adaptive model objects and their application in unified and comprehensive modeling of an industrial robot system. The proposed method makes it possible to utilize modeling and models that are applied in ...

The Resilient Packet Ring (RPR) is a data ring network, where one of the key issues is on a load balancing for competing streams of elastic traffic. This paper suggests efficient routing algorithms on the RPR. For the algorithms, we evaluate their ...

Competitive intelligence analysis is an information processing course for structured, semi-structured and non-structured text. Now it is very difficult to analyze intelligence information with the computer. In this paper, we put forward a SWOT strategy ...

Automotive vehicle drivability calibration comprises development activities that are most influential to the final human driving experience of the car. At the same time these activities are performed in the latest phases of the process where any ...

To avoid the needless trip by magnetizing inrush current, the second harmonic component is commonly used for blocking differential relay in power transformers. However, the second harmonic component in fault current is increased in long lines and ...

The analytical equation for the Liesegang operator has been obtained. The genetic relation between the Liesegang operator describing the behavior of the non-equilibrium oxyhydrate gel and the Hamiltonian of the vibrating sorption system is shown.

Having ...

Surface acoustic wave (SAW) dispersive delay lines (DDLs) are used to generate and compress frequency modulated chirp signals. The simplest DDL consists of two interdigital transducers placed on the piezoelectric substrate. The interdigital transducers ...

Raw hide, being an expensive starting material for manufacturing natural leathers, arrives in tanneries in a preserved state. In most cases, sodium chloride is used as preservation medium. In a whole number of operations through which raw hide is ...

Two different plants for enzymatic hydrolysis were used for presenting enzymatic hydrolysis of chrome shavings. In India an isothermal stirred reactor was employed, in Mexico we used a non- isothermal and nonadiabatic stirred reactor - a tanning drum. ...

The strong interaction between the discrete dynamic and the one continue is now seriously taken into account in the model. These models newborn so-called hybrid models describe at one time the two dynamics and are already used as well in control systems ...

We review a new form of self-organizing map introduced in [5] which is based on a non-linear projection of latent points into data space, identical to that performed in the Generative Topographic Mapping (GTM) [1]. We discuss a refinement of that ...

This paper presents a genetic-algorithm-based approach to the problem of UAV path planning in dynamic environments. Variable-length chromosomes and their genes have been used for encoding the problem. We model the vehicle path as a sequence of speed and ...

Considering the transitory character of its operation, the linear induction launcher has dynamic performances such as the propulsion force and the projectile velocity which are significantly dependent not only on its geometrical dimensions but also on ...

The exponential growth of the Internet and the trend toward providing differentiated classes of service has placed heavy burdens on network management and control operations. Adding more resources may temporarily relieve congestion conditions, but it is ...

In this paper, we proposed a new method for phylogenetic analysis, based on graphic representations of DNA sequences. Utilizing the invariants of graphs, we give the distance measure of DNA sequences and define the distance between species. We have ...
