The main purpose of this project is to build a bank system that offers a friendly and simple interface to let users easily manage their lightweight currencies. The Lightweight Currency Protocol (LCP) was originally proposed to solve the problem of fairness in resource cooperatives. However, there are other possible applications of the protocol, including the control of spam and as a general purpose medium of exchange for low value transactions. This project investigates the implementation issues of the LCP, and also investigates LCP bank services to provide human interface to currency operations.

The purpose of this project is to design, build, and implement a Customer Relationship Management (CRM) system for a bank. CRM BANKING is an online application that caters to strengthening and stabilizing customer relationships in a bank.

The purpose of this project is to use Java technology to create an instant messenger application that could be used by any person who has the basic knowledge of working with a graphical user interface. The goal here is to develop an application that provides communication to users running different operating systems.

The purpose of this project is to develop a Java Applet that provides all the tools needed for creating image fantasies. It lets the user pick a template and an image, and combine them together. The user can then apply image processing techniques such as rotation, zooming, blurring etc according to his/her requirements.

The purpose of this project is to investigate the use of the emerging XML technologies to improve online Business to Business (B2B) supply chain processes.

Esta infra-estrutura baseia-se em um modelo de componentes neutro em termos de tecnologia e especificado inteiramente em UML (Unified Modeling Language). A plataforma utiliza Web Services para comunicação síncrona entre os componentes. Um Serviço de Notificação baseado em documentos XML (Extensible Markup Language) foi desenvolvido para suporte a notificação assíncrona entre componentes. Um exemplo de aplicação na área de gerência de redes ilustra as funcionalidades da infra-estrutura / Abstract: This work presents an infrastructure for supporting component-based software development for mobile devices with limited resources regarding processing power and storage. This infrastructure is based on a neutral component model in terms of technology and specified entirely in UML (Unified Modeling Language). The platform employs Web Services for synchronous communication between components. A Notification Service based on XML (Extensible Markup Language) documents was developed in order to support asynchronous communication among the components.

Tout le monde a déjà rencontré la fonctionnalité ``Undo/Redo' qui permet de se balader dans les versions précédentes d'un document. Bien que le versioning -- sauver et parcourir plusieurs versions d'entités données -- est nécessaire pour beaucoup d'applications, il est difficile de l'implémenter facilement et efficacement en temps et en espace utilisés. Dans cette thèse, nous présentons un système de versioning efficace et expressif pour les langages orientés objet. <p><p>Nous commencons par développer un modèle qui permet au développeur de sélectionner avec précision les parties intéressantes de son système qui seront sauvegardées à des moments clefs. Ce modèle permet de parcourir facilement les différentes versions enregistrées et de faire cohabiter aisément les parties versionnées avec les parties non sélectionnées par le développeur. Ce modèle est de plus compatible avec trois types de versioning (linear, backtracking et branching versioning) qui permettent des opérations diverses sur la ligne du temps, comme supprimer toutes les versions après une version donnée ou créer une nouvelle branche à partir d'une ancienne version. <p><p>Ensuite nous développons les structures efficaces en temps et en espace qui implémentent ce modèle dans un monde réel. Basées sur les travaux de Driscoll et al. elles sont adaptées aux spécificités de chaque type de versioning. <p><p>Nous montrons ensuite comment ce système peut être intégré concrètement dans un langage orienté object. Plus précisément, nous montrons comment notre système peut être intégré de façon transparente pour le développeur grâce à des outils tels que les aspects ou la transformation de bytecodes. <p><p>Pour valider nos propos, nous avons implémenté notre système dans les langages de programmation Smalltalk et Java. Nous montrons des applications réelles qui l'utilisent, telles que les post-conditions à états et le problème du planar point location. <p><p>Nous terminons cette thèse par évaluer l'efficacité de notre implémentation en effectuant des benchmarks détaillés en Smalltalk et en Java. Nous avons notamment étudié l'espace pris par nos structures données et le temps d'éxecution de chaque opération de versioning. / Doctorat en Sciences / info:eu-repo/semantics/nonPublished

In this thesis, we have developed a flow-sensitive data flow analysis framework for value set analyses for Java-like languages. Our analysis frame work is based on access paths—a variable followed by zero or more field accesses. We express our abstract states as maps from bounded access paths to abstract value sets. Using access paths instead of allocation sites enables us to perform strong updates on assignments to dynamically allocated memory locations. We also describe several optimizations to reduce the number of access paths that need to be tracked in our analysis. We have instantiated this frame work for flow-sensitive pointer and null-pointer analysis for Java. We have implemented our analysis inside the Chord frame work. A major part of our implementation is written declaratively using Datalog. We leverage the use of BDDs in Chord for keeping our memory usage low. We show that our analysis is much more precise and faster than traditional flow-sensitive and flow-insensitive pointer and null-pointer analysis for Java. We further extend our access path based analysis frame work to concurrent Java programs. We use the synchronization structure of the programs to transfer abstract states from one thread to another. Therefore, we do not need to make conservative assumptions about reads or writes to shared memory. We prove our analysis to be sound for the happens-before memory model, which is weaker than most common memory models, including sequential consistency and the Java Memory Model. We implement a null-pointer analysis for concurrent Java programs and show it to be more precise than the traditional analysis.

Increasing speed of networks and worldwide availability has made the World Wide Web the most significant medium for information exchange. Web technologies have become more and more important as large and small businesses continue to make their presence on the web. Today's businesses have more than just a "face" on the worldwide web. The use of a web browser is no longer restricted to viewing static pages. Browsers are becoming more and more a standard interface to a multifaceted reign of programs that live on the worldwide web. Two main technologies stand out for the implementation of web applications, Sun Microsystems' Java 2 Enterprise Edition (J2EE) and Microsoft' Dot Net Framework. The purpose of this study is to provide an unbiased comparison of the two technologies based on performance and other software qualities.

In this project a collaboration multimedia toolkit, JSCMT (Java Synchronized Collaborative Multimedia Toolkit) was developed which is intended to connect a group of people located in different geographical locations who are working on the same project.
