In this paper, we present an approach for designing security warnings in vehicles for software based security incidents. With this we pursue the goal of reducing safety relevant component failures, which can be caused by manipulated or malicious software. The basis of our work is a theoretical analysis of the correlation of manipulated software (including malware) in automotive systems with the safety relevant failures of system components. We describe the potential of a security warning, which can be presented in time ahead of a traditional safety warning: The latter would only indicate safety-relevant implications that potentially arise later as an implication of the preceding security incident. In this paper we suggest three exemplary icons for a combined security-safety warning. Combined warning means a warning not at the time of a safety-relevant failure but already in the detection of the security-violation (e.g. manipulated software in the vehicle). An essential precondition is a recognition algorithm for such malicious software, which has been examined in previous research like [3]. Based on theoretical analyses, we introduce an exemplary design for the testing of these warnings in a virtual environment, precisely, in a driving simulator. A couple of factors play a central role in such evaluations, such as: perception, reaction of the driver, interpretation of warnings and security awareness. The results can be interpreted in the context of the fundamental aim: the reduction of accidents by security alerts. They thus serve as a recommended course of action for implementation in future vehicles. © 2010 ACM.

The analysis and characterization of biomedical image data is a complex procedure involving several processing phases, like data acquisition, preprocessing, segmentation, feature extraction and classification. The proper combination and parameterization of the utilized methods are heavily relying on the given image data set and experiment type and may thus require advanced image processing and classification knowledge from the side of the biomedical expert. In this work, an application, exploiting web services and applying ontological modeling, is presented, to enable the intelligent creation of image mining workflows. The described tool can be directly integrated to the Rapid-Miner or similar workflow management platforms. A case study dealing with the creation of a sample workflow for kidney biopsy microscopy images analysis is presented to demonstrate the functionality of the proposed framework. © 2010 IEEE.

A system that uses adaptive beamforming techniques for mobile Digital Video Broadcasting Satellite (DVB-S) reception is proposed in this paper. The purpose is to enable DVB-S reception in moving vehicles. Phased arrays are able to electronically track the desired signal during dynamic behaviour of the vehicle the array is mounted on. The proposed system uses blind beamforming to adapt the array steering vector to changing signal (conditions and) directions. Movement of the vehicle, the phased array is mounted on, leads to modulus and phase deviations at the beamformer output. An extended version of the Constant Modulus Algorithm (CMA) algorithm is used to adapt the steering vector weights to compensate for those deviations. For simulation of the proposed system a model of vehicle dynamics is used to generate realistic antenna data. Simulation of the proposed system based on this antenna data shows appropriate corrections for modulus and phase deviations. ©2010 IEEE.

Excessive lose of customer account is becoming a major headache for VIP E-Mail hosting companies. Analysis of what kind of customer is more prone to lose and finding the appropriate measures to sustain those customers has become urgent needs. Recently, classification models based on mathematical programming have been widely used in business intelligence. The purpose of this paper is to propose several multiple criteria programming methods for classification and apply these methods to VIP E-Mail behavior classification. We first introduce a model for a generalized multiple criteria programming based classification method, specifically four particular forms, and then we use a cross-validation method to test the stability and accuracy of multiple criteria programming methods on VIP E-Mail accounts. Finally, we compare our models with Support Vector Machine (SVM). The results show that the classification models based on mathematical programming are satisfactorily accurate and stable on a VIP E-Mail dataset. Therefore, it can be concluded that applying the proposed method on VIP E-Mail behavior analysis can provide stable and credible results. © 2010 - IOS Press and the authors. All rights reserved.

The type of the leaf vein can be a useful parameter in automatic identification of plant species. Leaf vein extraction is the precondition of discriminating the leaf vein type. In this paper a new method is presented for leaf vein extraction based on mathematical morphology. Firstly, the color image of the plant leaf is transformed to gray image according to the hue and intensity information. Secondly, a combined operation of mathematical morphology is applied to the image to eliminate the color overlap between the whole leaf vein and the whole background. Thirdly, image segmentation is performed with OSTU method. Finally, the leaf vein can be got after some processing on details. Experiments have been conducted with several images and the results show the effectiveness of the method. The basic idea of the method is also applicable to other linear objects extraction. ©2010 IEEE.

In this paper we present a glancing review of how to define the time schedule of Simulated Annealing (SA) algorithm in different articles that applied them to solve the traveling salesman problem (TSP). In the following subjects we introduce a new definition of this concept in relation to other parameters. In other word, we claim a novel description of initial temperature, Markov chain and final temperature to the basic algorithm of SA that gives an introduction to New Time Schedule Simulated Annealing (NTSSA). In this method, the dynamic coincidence of time schedule parameters and temperature conditions is a possible happening among the searching process. In continuation we present the obtaining results of proposed algorithm in solving TSP in comparison with basic methods of SA and other intelligent optimization methods. The surprising improvement in results obtained by this approach shows the efficiency of NTSSA in contrast with other basic optimization methods.

This paper presents the fuzzy modeling approach to the description QV curve of power system for analysis of voltage stability. Voltage instability of power system comes from increasing load rapidly, and causes bus voltage to drop. When voltage is out of control and it can be voltage collapse. The QV curve can identify voltage stability limit, and it determine robustness of power system. The method of fuzzy modeling has been proven to be well-suited for modeling nonlinear industrial processes described by input-output data. In view of the nonlinear characteristic of the QV curve, the method of fuzzy modeling is employed for representing the curve. The fuzzy system model is basically a collection of fuzzy IF-THEN rules that are combined via fuzzy reasoning for describing the features of a system under study. Based on the Sugeno-type fuzzy model, various models with different numbers of modeling rules are used to describing the QV curve. It is found that such fuzzy model offers both quantitative and qualitative descriptions for the QV curve.

This paper presents the design of modal insensitivity for the synchronous generator in a power system using Eigenstructure Assignment. In the proposed design procedure, modal insensitivity of generator is achieved by assigning system eigenstructure and only algebraic computations are involved. Model insensitivity means that the concerned system mode shape is insensitive to small variations in the system. From the simulation results of the study in a single-machine-infinite-bus system are certified. It is found that the system damping has been greatly improved. The proposed design has improved on the sensitivity.

This paper used six formulas for power factor measurement, and they will be different according to the characteristics of load. The power quality is more and more serious, because a lot of information technology equipments and power electric converters were used in recent years. Harmonic and load unbalance can affect the measurement result of power factor of utility. The Fast Fourier Transform (FFT) is used to analyze the six formula of power factor. The simulation system was modeled in Hardware Description Language (VHDL) and some novel IP (intellectual property) cores, such as CORDIC core and FFT core by the way of Bottom-Up. The technology of semiconductor was more and more maturely. Design of SOC (System On a Chip) is a trend to achieve the strong and small volume in the future. The measurement data were employed to calculate active, reactive and apparent power. The average error rate of our design is about 0.05%.
