Hypertension and arrhythmia are chronic diseases, which can be effectively prevented and controlled only if the physiological parameters of the patient are constantly monitored, along with the full support of the health education and professional medical care. In this paper, a role-based intelligent mobile care system with alert mechanism in chronic care environment is proposed and implemented. The roles in our system include patients, physicians, nurses, and healthcare providers. Each of the roles represents a person that uses a mobile device such as a mobile phone to communicate with the server setup in the care center such that he or she can go around without restrictions. For commercial mobile phones with Bluetooth communication capability attached to chronic patients, we have developed physiological signal recognition algorithms that were implemented and built-in in the mobile phone without affecting its original communication functions. It is thus possible to integrate several front-end mobile care devices with Bluetooth communication capability to extract patients' various physiological parameters [such as blood Pressure, pulse, saturation of haemoglobin (SPO2), and electrocardiogram (ECG)], to monitor multiple physiological signals without space limit, and to upload important or abnormal physiological information to healthcare center for storage and analysis or transmit the information to physicians and healthcare providers for further processing. Thus, the physiological signal extraction devices only have to deal with signal extraction and wireless transmission. Since they do not have to do signal processing, their form factor can be further reduced to reach the goal of microminiaturization and power saving. An alert management mechanism has been included in back-end healthcare center to initiate various strategies for automatic emergency alerts after receiving emergency messages or after automatically recognizing emergency messages.

We report on the development of a java-based application devised to support collaborative teaming of Art concepts and ideas over the Internet. Starting from an examination of the pedagogy of both Art education and collaborative learning we propose principles which are useful for the design and construction of a "lightweight" software application which supports interactive Art learning in groups. This application makes "dynamics" of an artwork explicit, and supports group interaction with simple messaging and "chat" facilities. This application may be used to facilitate learning and teaching of Art, but also as a research tool to investigate the learning of Art and also the development and dynamics of collaborating groups. Evaluation of a pilot study of the use of our system with a group of 20 school children is presented.

This paper describes JES, a java Execution Simulator that allows users to explore how a java program executes. This interactive simulator displays a representation of a java program and animates the running of the program. Instructors can use JES to demonstrate how data is moved when variables are assigned, when parameters are passed, and when values are returned by a method. JES is useful for comparing how primitive and object values are manipulated. The simulator also demonstrates scope rules, object creation, inheritance and polymorphism. While the simulator only supports variables of type double and object and does not support conditionals or looping, it allows users to write general java pro-rams that might be used as examples in the first weeks of a CS I course. JES also has support for arrays of doubles and objects. The simulator is written in java and can be run as an application or an applet. Support for the simulator includes a simple mechanism for quickly running the simulator on a program developed with a standard java development system.

A new software tool for the automatic detection and monitoring of plumes caused by major industrial accidents is described. This tool has been designed in order to use, near real time information as provided by satellite images, perform sophisticated image analysis and elaborate a user-friendly operational environment for the detection of plumes caused by major industrial accidents. The methodology, based on NOAA/AVHRR (Advanced Very High Resolution Radiometer) imagery, uses a two-dimensional feature space in order to discriminate pixels that contain plumes from those that correspond to clouds or to the underlying surface. The two-dimensional feature space is generated by combining AVHRR channels 1(visible), 2 (near infrared) and 5 (thermal infrared). The software tool proposed has been coded in java2 language, using the concepts of interoperability and object-oriented programming. This study demonstrates the applicability of the tool for the detection of a plume caused by a massive explosion in a firework factory in Enschede, The Netherlands, on May 13, 2000. The effectiveness and reliability of the software tool was found to be satisfactory, as plume was automatically detected and discriminated from the underlying surface. (C) 2005 Elsevier Ltd.

java is evolving into a full-scale system development technology by the addition of functions such as Applets, object-oriented programming, cross-platform support, internationalization, javaBeans, Remote Method Invocation (RMI), java Database Connectivity (JDBC), Enterprise javaBeans (EJB), java Plug-in, HotSpot Client Virtual Machine (VM), java Naming and Directory Interface (JNDI), RMI/Internet Inter-ORB Protocol (IIOP), eXtensible Mark-up Language (XML) support, and java Secure Socket Extension (JSSE). These functions have been added in three specifications: java 2 Platform, Enterprise Edition (J2EE);java 2 Platform, Standard Edition (J2SE);and java 2 Platform, Micro Edition (J2ME). Also, the manner in which these specifications are decided has shifted from decisions made by Sun Microsystems to decisions made by an open community through a process called the java Community Process (JCP). The main key-phrase of the latest trend in java/EJB is "Ease of Development," and J2SE 1.5 (code name "Tiger") will play a central role in this trend. Prospective enhancements in the java programming language specifications such as Generics, Enhanced for Loop, Autoboxing/Unboxing, Typesafe Enums, Varargs, Static Import, and Metadata are expected to simplify system development, learning, and mastering. With these new technologies, java will be used by a wider range of developers and EJB-based development of enterprise systems will become more popular.

Due to its relative newness and popularity, java is being taught to numerous non-novice programmers both in industry and in academia. Claims have been made that certain background characteristics of programmers relate to ease in learning java. In this study, background information of 135 non-novice programmers was obtained, together with data relating to their difficulty of learning several different features of java. Results of this study could be used by software project managers contemplating the use of java, and by academicians involved in curricular planning. (C) 2003 Published by Elsevier B.V.

Web projects have been mushrooming in the last decade with no standard cost model. A Web business can track how long it takes to do a Web related task for better-cost estimations. In this paper, a Web project cost estimation model is developed that uses fuzzy number concepts to model the time it takes to perform a Web task. A software tool that uses this model, called 'Web Task Timer, is implemented This application serves as a timer tailored for timing specific Web task times. It calculates lower and upper bounds on the time spent for Web tasks, and generates fuzzy numbers to represent the time for each Web task. The application also generates cost ranges for each task based on hourly wage of an individual Web developer.
