Automatic path-oriented test data generation is not only a key problem but a hot issue in the research area of software testing today. Genetic algorithm (GA) has been used to path-oriented test data generation since 1992 and outperforms other approaches. A fitness function based on branch distance (BDBFF) has been applied in GA-based path-oriented test data generation. To investigate performance of this method, a triangle classification program was chosen as the benchmark. Using binary string coding, four combinations of selection and crossover operations were used to study performance of this method. Furthermore, the relationship between size of search space and average number of test data or average time was analyzed.

We demonstrate a novel method to segment the tongue image automatically with the mouth location method and active appearance model (AAM). With the help of a particular feature of the mouth, we could locate the dark hole's position easily and quickly. For the close relationship between the mouth and tongue, we would predict the approximate area of the tongue. Then we apply the AAM to segment the tongue from the image completely, which uses texture and shape of an object. During the AAM search, we constrain the initial displacement and size in the approximate area. For those images that failed to locate the mouth, we use a multi-initial displacement method during the AAM search to optimize the result. The experiment shows that our method is accurate and effective.

In this paper, I present a new approach for generating sub-words using the Chebyshev Polynomials in place of traditional S-Box formation in AES algorithm, which is based on using look-up tables. S-Box computation is a time-consuming operation in AES algorithm as it is required in every round. So it is desirous to overcome the overhead of S-Box computation using any other computational techniques. It is in my best of knowledge that it is a truly new approach for expanding keys in Passport Protocol.

With the rapid development of the communication technology, the Internet plays a more and more important role in many applications of healthcare. In healthcare field, mental disorder treatment is an important topic, with cognitive behavioral therapy and biofeedback therapy as two emerging and noteworthy methods. A number of researches on the integrations of the Internet and mental healthcare have been proposed recently. Thus, this research aims at the development of an online treatment system for panic patients by combining the cognitive behavioral therapy, biofeedback therapy, and web technologies. The system provides a more convenient communication between patients and medical personnel. The essential treatments and some related information provided by the medical personnel can be downloaded or used online by the patients via a web-based interface. On the other hand, important information such as physiological data can also be uploaded to the server databases automatically. Therefore, considerable time on the treatments can be saved for both patients and therapists, and the medical costs can be highly reduced. The experimental results show that the curative effects of the mental disorder patients are highly depend on the physiological status. The results of this research are expected to provide useful insights for the field of mental disorder treatment. © 2009 by Knowledge Systems institute Graduate School.

Facial expression recognition is one of the most popular topics in emotion analysis. Most facial expression recognition systems are implemented by general expression models. Since facial expressions may be expressed differently by different people, inaccurate results are unavoidable. The proposed facial expression recognition system recognizes facial expressions using facial features of the individual user. Experimental results show that the proposed system can accurately identify the emotions of facial expressions.

This paper reports on AnnieWAY, an autonomous vehicle that is capable of driving through urban scenarios and that has successfully entered the finals of the 2007 DARPA Urban Challenge competition. After describing the main challenges imposed and the major hardware components, we outline the underlying software structure and focus on selected algorithms. Environmental perception mainly relies on a recent laser scanner which delivers both range and reflectivity measurements. While range measurements are used to provide 3D scene geometry, measuring reflectivity allows for robust lane marker detection. Mission and maneuver planning is conducted using a concurrent hierarchical state machine that generates behavior in accordance with California traffic laws. We conclude with a report of the results achieved during the competition. © 2009 Springer-Verlag Berlin Heidelberg.

This paper proposes a novel type-2 fuzzy ontology, including a type-2 food ontology and a type-2 FML-based ontology, for diet assessment. In addition, the paper presents a type-2 fuzzy diet assessment agent. In the proposed approach, firstly, the nutrition facts of various kinds of food are collected from the Internet and the convenience store. Next, the domain experts construct the type-2 fuzzy ontology, then the involved volunteers are requested to input eaten items. Finally, the proposed agent displays the diet assessment of the input eaten items based on the constructed type-2 fuzzy ontology. The experimental results show that the proposed approach is feasible for diet assessment.

In order to make surfing the internet faster, and to save redundant processing load with each request for the same web page, many caching techniques have been developed to reduce latency of retrieving data on World Wide Web. In this paper we will give a quick overview of existing web caching techniques used for dynamic web pages then we will introduce a design and implementation model that take advantage of 'URL Rewriting' feature in some popular web servers, e.g. Apache, to provide an effective approach of caching dynamic web pages.

Resistive superconducting fault current limiters (SFCL's) are assumed to be a prospective solution for commercialization. But in spite of excellent current limiting performances realized by resistive SFCL's, commercialization and installation of SFCL's have been delayed due to difficulties in overcoming several technical problems such as a coordination with conventional relays. Resistive SFCL's may have difficulty in controlling an initiation of current limiting operation that sometimes is very important for coordination with relays, because the superconductor in the SFCL will quench immediately after the fault current reaches its critical current. In order to solve these problems, a novel hybrid SFCL of the first half cycle non-limiting type was developed. This paper presents the characteristics of this hybrid SFCL, its configuration and test results. © 2009 IEEE,.
