The goal of this research is a proposal of a standard model for vehicle system simulations. Recently, the CO 2 reduction and efficiency improvement of the energy consumption are important subjects in development of the vehicle systems. The new technologies related to vehicle development have continued to increase in complexity. For these reasons, the energy management simulation by the coordinated design of an electric system and vehicle system is required. The electrical behavior of the batteries becomes important to improve the energy management in the vehicle systems. The battery modeling technologies and the application example for vehicle system simulation are reported.

Workflow is the technology of implementing automated process. It has a wide use in many fields. The study of workflow engine is a key problem of implement of workflow system. The traditional workflow engine has many limits in practice. In order to reduce cost, shorten developing cycle and raise product competitiveness, open source softer ware become more and more popular in enterprise application. jBPM based on J2EE is most prone to be commercialized in the open source workflow engine domain. But before designing jBPM workflow, it should install eclipse plug-in first. It is a shortcoming especially in the system which has a high demand of time. This paper is in tented to use JavaScript to design a compiler based on MVC pattern, to solve this problem and expand the jBPM engine interfaces to better meet the application in the real-time system with better flexibility, transplant ability. © 2011 IEEE.

Detecting unknown malicious executables is a challenging task. Traditional anti-virus systems use signatures to detect malicious executables. However, the method cannot detect unseen instances or variants. Inspired by biological immune systems, an immune-based approach for detection of unknown malicious executables is proposed in this paper, which is referred to MEDMI. The approach can use the benign executables to be the training set for building the profile of the system and then generates detectors to detect malicious executables. The experiments comparing with different detection methods show that the approach provides an effective novel solution to detect malicious executables. © Maxwell Scientific Organization, 2012.

The present work focuses on the problem of aerothermodynamics of space vehicles with rounded edges on the hypersonic segment of the flight trajectory. Firstly, the in-house Navier-Stokes solver, UNIC-UNS code, with the slip boundary condition is used to simulate the flows around a spherical-nosed cylinder at different Knudsen numbers and Mach numbers, and compared with DSMC computations for validation. The Navier-Stokes simulations are in good agreement with that of DSMC. The hypersonic flows over the European eXPErimental Re-entry Test-bed (EXPERT) model are then simulated for a wide range of flow regimes, which correspond to the expected descent trajectory with allowance for rarefaction and thermochemical nonequilibrium. Three dimensional CFD analyses are presented for the complete geometry of the capsules considering the air dissociation and its effects on the flow structure and on the force and thermal loads for the hypersonic segment of the flight as a precursor to the future studies and to provide the scientific community with quality data that can be used to improve tools for the design of hypersonic vehicles. © 2012 by Wen, Saldivar Massimi, Chen, Liang, Bondar and Ivanov.

The performance of an fingerprint recognition system is measured by its accuracy in recognition. For a feature-based fingerprint recognition system, the accuracy is heavily depend on the chosen feature set. A fingerprint image may suffer from problems like translation, rotation, scaling and elastic distortion due to different imaging conditions. A fingerprint recognition algorithm should address these problems before building the feature set. We present a novel method of representing the fingerprint ridge shape as the feature set by combining chain code and fourier descriptor for fingerprint recognition. Experimental results shows that our proposed algorithm is reliable for fingerprint recognition. © 2011 Springer-Verlag.

This paper presents a novel scheme for face recognition by fusing local and global discriminant features. It has been observed that facial changes are occurred due to variations in facial expression, illumination condition, pose, etc. and these changes are often appeared only some regions of the whole image. The global features extracted from the whole image are not able to cope with these facial changes. To cope with the above facial changes face images are divided into a number of non-overlapping smaller sub-images and discriminant features are extracted from these sub-images as well as from the whole image. All these extracted local and global features are fused to form a large feature vector. We have used generalized two-dimensional fisher's linear discriminate (G-2DFLD) method to extract these local and global discriminant features. We have used the fisher's linear discriminate (FLD) method to extract lower dimensional discriminant features from the fused large feature vector. A Multi-class Support Vector Machine (SVM) is applied on these reduced feature vector for classification. The proposed method was evaluated on AT&T Face Database and experimental results show that the performance of the proposed method is better than other global feature extraction methods like PCA, 2DPCA, PCA+FLD, 2DFLD and G-2DFLD methods. © 2011 IEEE.

For context based surfing of World Wide Web in a systematic and automatic manner, a web crawler is required. The World Wide Web consists interlinked documents and resources that are easily crawled by general web crawler, known as surface web crawler. But for crawling the hidden web data, in which the data is hidden behind the html forms requires special type of crawler, known as hidden web crawler. For efficient crawling of hidden web data, the discovery of relevant and proper html forms is very important step. For this purpose a technique for domain specific hidden web crawler is proposed in this paper. The proposed technique is based on the domain specific crawling of World Wide Web. In this approach, a link is followed in a step by step manner, which results in a large source of hidden web databases. Experiential results verify that the proposed approach is quite effective in crawling the hidden web data contents. Copyright © 2011 ACM.

Finding road intersections in advance is crucial for navigation and path planning of moving autonomous vehicles, especially when there is no position or geographic auxiliary information available. In this paper, we investigate the use of a 3D point cloud based solution for intersection and road segment classification in front of an autonomous vehicle. It is based on the analysis of the features from the designed beam model. First, we build a grid map of the point cloud and clear the cells which belong to other vehicles. Then, the proposed beam model is applied with a specified distance in front of autonomous vehicle. A feature set based on the length distribution of the beam is extracted from the current frame and combined with a trained classifier to solve the road-type classification problem, i.e., segment and intersection. In addition, we also make the distinction between +-shaped and T-shaped intersections. The results are reported over a series of real-world data. A performance of above 80% correct classification is reported at a real-time classification rate of 5 Hz.
