java's utility in developing distributed applications extends beyond the creation of more intuitive user interfaces and expansion of access. In its greater role in the world of distributed computing, java represents a body of programming interfaces that enable java applications to communicate which each other across a process boundary, simplifying the development, deployment, and maintenance of enterprise applications.

Each and every aspect of the modern society is affected by the technology. From extensive usage of electronic health records towards advances in engineering and technology, modern healthcare and its delivery methods are varying at an ever growing rate. A java based real-time data access and monitoring system using Bluetooth module can be helpful for continuous monitoring of patients to keep healthy environment. Along with the record maintenance, it can also serve as a remote monitor for chronic diseases. This proposal can act as a user interface to update data and can serve as backend program. In the front end side, processed real time data/signals communicated with microcontroller can be received successfully via Bluetooth technology [7] to the Bluetooth transceiver. java program will access the data and store it for analysis whenever needed using GUI. In hospitals, health records of the patients are being kept in database which can be accessed from anywhere in the amenity. This not only saves time but it also results in a better coordination and management of the data. The extensive use of technology in maintaining health records digitally has resulted in major savings in costs, as well as improved patients physical condition and safety. It is used to create an application for monitoring certain parameters such as temperature, sound intensity, bio-medical signals, pressure, humidity and more.

This paper presents the development of a math learning system for high school math students. The development process involved the creation of the front-end graphical user interface and the back-end database, with both being implemented to near-commercial standard. The front-end consists of two main screens;a separate one each for the teacher and the student. The teacher's screen displays and allows the editing of all data in the database through the use of tables. The student is presented with all the math questions from the database on their screen in a structured form for the practice of math problems of various difficulty levels. Three types of final tests were performed to examine the effectiveness of math learning system. The results showed that the system is consistent and usable for learning math at high school.

The outcome of test case execution depends on the state of the object under test. While testers can carefully choose meaningful and representative object states for test execution, it is unaffordable to cover the combinatorial space of possible object states exhaustively. An appealing option is to delegate part of the testing activities to the runtime and to execute test cases in the field whenever a new or uncommon state is observed. We have designed and developed Groucho, a framework for in-vivo testing of java applications. Among the challenges that we faced, the most important ones are isolation of the test session from the user session and minimal performance overhead. Experimental results show that if the activation probability is kept reasonably small (e.g., 10(-4)), the impact of the framework is imperceptible (i.e., either statistically insignificant or with a negligible effect size).

How .NET's custom attributes affect design

引用

IEEE SOFTWARE 2002年第5期19卷 18-20页

作者： Newkirk, J Vorontsov, AA Thoughtworks

In its first release of the .NET Framework, Microsoft has provided a defined method for adding declarative information (metadata) to runtime entities in the platform. These entities include classes, methods, properties, and instance or class variables. Using .NET, you can also add declarative information to the assembly, which is a unit of deployment that is conceptually similar to a .dll or .exe file. An assembly includes attributes that describe its identity (name, version, and culture), informational attributes that provide additional product or company information, manifest attributes that describe configuration information, and strong name attributes that describe whether the assembly is signed using public key encryption. The program can retrieve this metadata at runtime to control how the program interacts with services such as serialization and security. We compare design decisions made using custom attributes in .NET with the java platform.

Modern software systems accommodate complex configurations and execution conditions that depend on the environment where the software is run. While in house testing can exercise only a fraction of such execution contexts, in vivo testing can take advantage of the execution state observed in the field to conduct further testing activities. In this paper, we present the Groucho approach to in vivo testing. Groucho can suspend the execution, run some in vivo tests, rollback the side effects introduced by such tests, and eventually resume normal execution. The approach can be transparently applied to the original application, even if only available as compiled code, and it is fully automated. Our empirical studies of the performance overhead introduced by Groucho under various configurations showed that this may be kept to a negligible level by activating in vivo testing with low probability. Our empirical studies about the effectiveness of the approach confirm previous findings on the existence of faults that are unlikely exposed in house and become easy to expose in the field. Moreover, we include the first study to quantify the coverage increase gained when in vivo testing is added to complement in house testing.

In the paper, we describe selected functionality of the current version of a new software tool, called Physarum Soft, developed for programming Physarum machines and simulating Physarum games. The tool was designed for the java platform. A Physarum machine is a biological computing device implemented in the plasmodium of Physarum polycephalum or Badhamia utricularis that are one-cell organisms able to build programmable complex networks. The plasmodial stage of such organisms is a natural transition system that can be used as a medium for solving different computational tasks as well as creating bio-inspired strategy games.

Reinforcement Learning - RL is an important agent problem that was not approached using the tools provided by Agent Oriented Programming - AOP. AgentSpeak(L) and its Jason implementation based on java platform are representing state-of-the-art approaches of AOP based on the Belief-Desire-Intention - BDI model. Temporal Difference Learning - TDL is a passive RL method that can be used by an agent to learn its utility function while it is acting according to a given policy in an uncertain and dynamic environment. In this paper we present an approach for modeling and implementation of TDL using the Jason AOP language. So, our paper is presenting a contribution towards narrowing the gap between RL and AOP, by endowing BDI agents with TDL skills.

In our previous research we have presented the core functional and data components of a framework for the development and deployment of web-based applications. The framework enables the operation of multiple applications within a single installation and supports runtime evolution by dynamically recompiling classes based on the source code that is retrieved from the database. It is structured upon a universal database schema (meta-model). The contributions of this paper include a versioning mechanism that enables access to old data in their real context (i.e., within the version of the application that created this data), a proposal for selective recompilation of new classes that allows applications to evolve safely at the minimum processing cost, and a policy for handling active classes (i.e., classes that have running instances) that need to be dynamically recompiled in order to reflect changes.

Public key cryptography is widely used to provide security services. The PIG is the infrastructure that supports the public key cryptography and the revocation of the certificates implies one of its major costs. The goal of this paper is to introduce a java platform, to test, to evaluate and to dimension certificate revocation systems. The revocation platform includes our implementations of Overissued CRL, OCSP, CPC-OCSP and AD-MHT to perform the certificate status checking, as well as a simple protocol to perform the revocation requests called SCRP.
