On Performance Evaluation of Advance Irregular Alpha Multi-Stage Interconnection Network-2

In this paper, the author has proposed a new multi-stage interconnection network named as advance irregular alpha multi-stage interconnection network-2 (AIAMIN-2). The AIAMIN-2 is a single switch fault tolerant network. It is compared with modified alpha network (MALN) and irregular modified augmented baseline network (IMABN). Results show that AIAMIN-2 performs better than the MALN and IMABN in faulty and non-faulty conditions.

Driver Behavior Monitoring through Sensors and Tracking the Accident using Wireless Technology

the driver behavior is one of the ways to prevent the fatal accidents and it is necessary to alert the driver when they are drowsy or in a distracted state. Distraction and drowsiness of the driver have been important factors for a large number of major accidents .They reduce the decision making capability and the perception level of the driver which negatively affect the ability of the driver to control the vehicle. A large number of serious or fatal accidents are occurred due to excessive or inappropriate speed of the vehicle and fatigue nature of the driver. With the new developed systems (sensors) there is a possibility of self controlling the vehicle when the driver was drunk or reckless or fatigue in order to reduce the major accidents. There is also a possibility of tracking the location of the accident, if occurs, through wireless access technology (GSM, GPS) so that proper measures are taken at a correct time.

A New Composite Algorithm for Identifying the Stars in the Star Tracker

Identifying the stars of field of view(FOV) is a difficult stage in determining the attitude through star tracker. Stars identification algorithms identify the stars of FOV, creating patterns from the stars and comparing them with the information saved in the memory. This research presents a new algorithm composed of pyramid, liebe and planer triangle algorithms. It has at least 4 stars as the stars of FOV and forms a triangle pattern. This algorithm is simulated with 16000 stars in MATLAB. Its accuracy, needed memory and searching time are studied and compared with those of pyramid, Liebe and triangular methods. Two errors, centroiding and in fake stars, are considered in the simulation for more approaching towards real status. According to the obtained results, the new algorithm can well identify the FOV among 140 stars in which only four stars are real and the rests are false. Its searching time is 8% lower, comparing to pyramid method, despite their similar accuracies. It compares the areas and polar moments of the four triangles with the information saved in the memory to meet a unique response. Besides its robustness and proper performance, it includes the false stars as well.

Guided Waves Propagation in Two-layer Tubes: Effects of the Inner Part in Contact with Air in the Cavity

This paper studies the acoustic backscattering of short ultrasonic pulses by air-filled stainless steel-solid polymer two-layer cylindrical tubes immersed in water. The stainless steel one-layer tube is taken as a reference. The focus of this paper is on revealing the effects of physical characteristics of the solid polymer on the scattering phenomenon. The work is done from the calculation of the backscattered pressure, an inverse Fourier Transform, which provides a temporal signal. Wigner-Ville representation has been chosen in order to analyze the acoustic signal backscattered by each tube. For reduced frequencies ranging from 0.1 to 200, the resonance spectrum and resonance trajectories have shown the manifestations of the guided waves. In this respect, the bifurcation of the A0 wave to the A0 - and the A0 + waves has been observed. The authors investigate the reduced cutoff frequencies of the symmetrical and the antisymmetrical guided waves, specially the curves changes. The findings are then compared with those obtained for the stainless steel onelayer cylindrical tube. Reduced cutoff frequency values have also been extracted from Wigner-Ville time-frequency images. A good agreement has, therefore, been obtained. The study of acoustic scattering by stainless steel-solid polymer two-layer tubes has revealed the sliding of the reduced cutoff frequencies of A1 and S1 guided waves towards low values, due the repulsion phenomena. The relationship between reduced cutoff frequency and velocity of wave in the solid polymer is linear; which is a very interesting result.

Prevention of Virus Propagation in Mobile Network

Infections and malwares have the capacity to spread beginning workstation systems into versatile systems with the fast improvement of brilliant phone clients .Currently, there are three disease vectors utilized by portable malware to spoil versatile. A Bluetooth affiliation permits document exchange if the telephone's Bluetooth stack helps OBEX trade which most telephones do. MMS messages can encase not just sound and pictures, they can additionally convey executables. Some cell telephone infections utilize this disease vector excessively e.g., the infections from the Commwarrior precursors. It's simpler to reject a MMS message than it is to decline a Bluetooth record sending, in light of the fact that the interest comes earlier. In any case, the message by and large originates from some individual you know, as the infection sends itself to the cell telephone on the tainted telephone's phonebook in this way, you're more prone to open it. Finally, in the event that you embed a contaminated MMC card into your telephone, different projects on it can mechanically execute. This defilement vector is likewise utilized by the Commwarrior infection family. These are the contamination vectors as of now being used. The correspondence channel that could be utilized to exchange executable substance might be utilized to send an infection. These comprise of Wi-Fi interchanges, skimming the Web, synchronizing with a contaminated PC etc. We propose a two-layer system model for mimicking infection spread through in participation of Bluetooth and SMS. We examine two methods for controlling portable infection engendering. The primary method is pre immunization and versatile scattering systems.

Choosing Shape Features by means of Genetic Algorithms for Gylph-clustering of Historical Documents

The solution for a feature selection problem is presented in the field of document image processing. The choice of shape features for describing glyphs of historical documents is a non-trivial task since the variations of glyphs in different documents is innumerable. Hence, the manual selection of shape features would be a cumbersome task. To select a subset of features from a given set a genetic algorithm is used which optimises the result of a clustering process by x-means. The result of x-means is evaluated by using different quality measures. The optimisation methodology is illustrated within a case study, in which the selection of an appropriate set of features is a crucial part of the system. The intended application supports a user who is transcribing historical documents by showing him similar occurrences of a given glyph.
