data preprocessing is an important step in data mining. It is used to resolve various types of problem in a large dataset in order to produce quality data. It consists of four steps, namely, data cleaning, integration, reduction and transformation. The literature shows that each preprocessing step consists of various techniques. In order to develop quality data, a data miner must decide the most appropriate techniques in every step of data preprocessing. In this study, we focus on data reduction particularly data discretization as one important data preprocessing step. data reduction involves reducing the data distribution by reducing the range of continuous data into a range of values or categories. data discretization plays a major role in reducing the attribute intervals of data values. Finding an appropriate number of discrete values will improve the performance of the data mining modelling, particularly in terms of classification accuracy. This paper proposes four levels of data discretization taxonomy as follows: hierarchical and non-hierarchical; splitting, merging and combination; supervised and unsupervised combinations; and binning, statistic, entropy and other related techniques. The taxonomy is developed based on a detailed review of previous discretization techniques. More than fifty techniques are investigated, and the structure of the discretization approach is outlined. Guidelines on how to use the proposed taxonomy are also discussed.

TETRA (Terrestrial Trunked Radio) is the standard of DTRS (Digital Trunked Radio System) developed by the ETSI (European Telecommunications Standards Institute). Currently, TETRA has been selected as the power IT wireless backbone network in Korea while the traditional distribution automation system has used the wireless network of mobile service provider using CDMA (Code Division Multiple Access) and WCDMA (Wideband CDMA) modems. Therefore, the development of gateway platform is indispensable according to the change to the TETRA network. In this paper, we propose an embedded Linux-based gateway platform for transmitting industrial power IT protocol using TETRA network.

The demanding usage of wireless technologies has brought opportunities for the online learning communities to participate in network Based Project Learning (NBPL). However, if the projects in NBPL are not initiated by the industries, the graduate students are unable to gain the required skills in solving the real world problems. Lack of commitment from the non-office-based mobile workers due to the accessibility, availability and mobility constraints make the functionality of NBPL ineffective. In this paper, we introduce mobile NBPL which is integrated with Mobile Announcement System (MASY) in order to provide a great amount of freedom in accessing NBPL via mobile devices. This system is designed to facilitate student-lecturer-mobile worker interaction, provide broadcast information and ease collaborative work through the use of mobile devices. Besides, we also discuss the design, development and implementation of mobile NBPL, the architecture and the technology used as well as how the experiments are being conducted. The functionality testing has been carried out in the faculty of Information Technology and Quantitative sciences, Universiti Teknologi MARA (UiTM). A preliminary experiment result and experience that we have learned from this system will also be discussed.

One objective of the policy-based networking paradigm is to enable a formulation of operational goals on level that is more generic and abstract than the low level configurations understood by various networking devices. However, implementation of these policies often appears to be inflexible and complex solution in the context of heterogeneous network environment. Recent innovations in the field of ontologies can significantly simplify the management system by reducing the complexity of modules and interactions, providing unified data interfaces and integrating different types of knowledge into single large, extendable and scalable policy framework. Current paper describes ontology oriented QoS policy description and management framework for heterogeneous network environment (wireless, wired, broadcast) developed in NETQOS project. It focuses on the policy-based QoS management in accordance with actors' preferences. The proposed approach is based on flexible and open architecture and includes semantic decomposition of the policies and data based on ontologies. Moreover, the proposed solution impacts the overall functioning of the policy management system with respect to implementation of user interfaces, interaction of components and enforcement directives. © 2008 IADIS.

This paper proposes a new concept of the genetic robot which has its own robot genome, in which each chromosome consists of many genes that contribute to defining the robotpsilas personality. The large number of genes also allows for a highly complex system, however it becomes increasingly difficult and time-consuming to ensure reliability, variability and consistency for the robotpsilas personality while manually initializing values for the individual genes. To overcome this difficulty, this paper proposes an evolutionary algorithm for a genetic robotpsilas personality (EAGRP). EAGRP evolves a gene pool that customizes the robotpsilas genome so that it closely matches a simplified set of features desired by the user. It does this using several new techniques. It acts on a 2 dimensional individual upon which a new masking method, the Eliza-Meme scheme, is used to derive a plausible individual given the restricted preference settings desired by the user. The proposed crossover method allows reproduction for the 2-dimensional genome. Finally, the evaluation procedure for individuals is carried out in a virtual environment using tailored perception scenarios.

In this study, handshake protocol for patient, medical center and doctor, medical center is proposed for electronic medical record transmission to improve the confidentiality of data transmission and non-repudiation of sending and receiving medical records. The proposed topology depends on symmetric and asymmetric cryptography to achieve high level of secrecy for electronic medical records. The new topology has been described on multi-users (i.e., Doctors and Patient). The new topology has been implemented using Ntru crypto-system and AES encryption method. The proposed solution has been tested to have high level of confidentiality up to the legal age of the medical records. © 2010 Asian network for Scientific Information.

Digital broadcasting is a novel paradigm for the next generation broadcasting. It can offer a new opportunity for interactive services such as content-based browsing, non-linear navigation, usage of user preference, and history, etc. On the other hand, one of the important factors for this new broadcasting environment is the interoperability among providers and consumers since the environment is distributed. Therefore a standard metadata for digital broadcasting is required and TV-Anytime metadata is one of the metadata standards for digital broadcasting. It is defined using XML schema, so its instances are XML data. In order to fulfill interoperability, a standard query language is also required and XQuery, which is a forthcoming standard query language for XML data, is a natural choice. In this paper we propose an efficient XML data management system that supports TV-Anytime metadata, especially using XQuery as a query language. Since the volume of metadata would be very large in real situation, our system considers a relational database system as storage. We implement a prototype system and test performance for various typical queries by comparing our system with other general-purpose systems. © Springer-Verlag Berlin Heidelberg 2005.
