Outdoor location systems based on wireless access point (WAP) signal strength must either know the exact location of the WAPs in order to use a triangulation algorithm, or must construct a radio-map of the signal strengths. While the radio-map technique increases accuracy and can accommodate a wireless network that is not owned by any one entity, conventional methods for constructing a radio-map are labor-intensive and impractical in such environments. We introduce a toolkit for automatically constructing outdoor radio-maps. Our toolkit can easily be carried by delivery personnel and security guards during their normal work duties to obtain signal readings. The scattered data readings are then fed into an interpolation algorithm to construct a more complete grid that can be used as the radio-map.

The World Wide Web provides new opportunities for distance education over the Internet. The Web, when combined with other network tools can be used to create a virtual classroom to bring together a community of learners for interactive education. In the paper we purpose the moving some of educational instructions of the Institute of Science Dokuz Eylul University at the WWW. This objective is achieved by investigating the use of emerging network technologies for training full time students and part time students. This research uses the electronic educational materials already available on the Web; and it evaluates the effectiveness of various collaborative tools.

Mobile ad hoc networks (MANET) are autonomous, infrastructureless networks that support multi-hop communication through IP routing. MANET and Internet have many differences. These differences are not only the structure and topology of the networks, but also communication patterns of nodes in both networks. Therefore, it is a challenging problem for MANET to access to the Internet due to these differences. There are many kinds of accessing mode such as single fix gateway or multi-gateway, where load-balancing is the most important problem. In this paper, we propose the dynamic gateway concept that acts as an interface between MANET and the Internet. These dynamic gateways can use mobile IP and DSDV protocol when they communicate with the Internet and interact with MANET, respectively. The dynamic gateway is used to solve the load-balancing problem. Several simulation experimental results in the dynamic gateway environment show that the performance of network has been improved.

Structural comparison of proteins is considered as one of the highly focused research areas in the field of bioinformatics. Structural similarity estimation techniques using singular geometric parameters derived from spatial coordinates of protein structural atoms have been reported previously, but it is also ascertained that a single geometric parameter based structural estimation can result in misconstrued classification and functional interpretation. In this paper we propose a novel geometric parameters based comparison protocol that uses previously unexplored pair of dihedral angles NC/sub a/NC/sub a/ and NCNC for similarity search. An orthonormal transformation is employed on the two-dimensional distribution for feature extraction and selective feature-space is represented in an indexing schema later used for similarity calibration. The results demonstrate the success of this dimensionality reduction based similarity measure in performing a rapid and length-independent similarity analysis of the protein structures.

Diabetic retinopathy (DR), a major complication of diabetes and the leading cause of new cases of blindness among adults, can be cured by the early and precise detection of the disease. An important aspect of DR is the micro-vascular changes that cause detectable changes in the appearance of retinal blood vessels. In this paper, we propose a new blood-vessel detection technique in retinal images, based on the regional recursive hierarchical decomposition using quadtrees and post-filtration of edges. We exploit the fact that in retinal images, the blood vessels appear as focal and/or penumbral blurred edges, which can be characterized by an estimable intensity gradient, which also serves in dismissing false alarms to a large extent. Our technique provides information on retinal blood vessel morphology that can be calibrated to normal expected blood vessel diameters and which can detect fine blood vessel anomalies that characterize the blood vessel pathology and hence aid early detection of diabetic retinopathy.

In software development, many kinds of knowledge are shared and reused as software patterns. However, the relation analysis among software patterns by hand is difficult on the large scale. In this paper, we propose a technique for the automatic relation analysis among the patterns. Our technique is based on a new pattern model to treat various patterns, and utilizes exiting text processing techniques to extract patterns from documents and to calculate the strength of pattern relations. As a result of experiments, the system that implements our technique has extracted appropriate relations among patterns without information on relations described in original pattern documents. Moreover, our system has the ability to suggest relations among patterns that the author has not noticed.

A pervasive computing environment consists of numerous casually accessible, frequently mobile, embedded, handheld devices capable of sensing the environment around it and reacting intelligently to simplify user activities. These devices are distributed everywhere at office, homes, stores, classroom, and are often connected to ad-hoc network and the Internet providing access from anywhere and anytime. Access control mechanisms can sometimes fail to provide complete security to these pervasive computing devices as witnessed in infrastructure based networks. The addition of pervasive computing devices to infrastructure based networks makes the problem of intrusion detection even harder. In this paper, the challenges and characteristics of intrusion detection in pervasive computing devices are discussed along with a mobile agents-based solution for both for a network environment made up of infrastructure based network and pervasive computing devices.

This method has been designed on the basis of software Capability Maturity Model (SW-CMM) and the multi-level fuzzy inference model and is used as a measurement and analysis tool. Among the most important characteristics of this method one can mention simple usage, accuracy, quantitative measures and comparability. Fuzzy logic-based tools are designed to provide such functions.

In card games, two or more players can act as colluders: they exchange information in order to collectively win the game. Electronic games (e-gaming) are supposed to be played under secure e-gaming protocols. Hence some tricks cannot be performed: card exchange, knowledge of opponent cards without their consent, shuffling and dealing the deck for one's own benefit, etc. Therefore, if two or more players collude, all they can do is exchange information. In the real world, other players can usually discover such colluders but, in a virtual world, colluders can use several ways to collude: cellular phones, instant messaging software,... they could even be seating next to each other while playing. In this paper, several methods to detect collusion in virtual card games are described.
