Simulation and statistical applications often mimic the behavior of a random phenomenon by way of generating random observations that form a known or empirical probability distribution with estimated parameter values. Generation of such random observations is called Random Variate Generation (RVG). The number of simulation and statistical applications provided on the World Wide Web (Web) is on the rise. To facilitate the development of simulation and statistical applications on the Web by way of reuse, there is a need for providing RVG as a Web service. This research involves the development of such a Web service for RVG, which can be invoked programmatically over the Web by using SOAP over the HyperText Transfer Protocol (HTTP) running on top of the Internet. To provide the RVG Web service, an RVG Web application is developed based on the Java 2 Enterprise Edition (J2EE) architecture. The RVG Web application is engineered by using the IBM WebSphere Studio Application Developer and runs on the IBM WebSphere Application Server. A client simulation and statistical application may call the RVG Web service and request the generation of random variates from 27 probability distributions. In addition, the RVG Web service also provides general statistics, scatter plot, and histogram of the requested random variates. The plots and histograms are created in Scalable Vector Graphics (SVG). The RVG Web service: (a) accepts requests in the Extensible Markup Language (XML) format, which is specified according to a request schema, and (b) sends the results to the client application also in the XML format specified according to a reply schema. The interface specification and access information needed to invoke the RVG Web service are provided in the Web Service Description Language (WSDL) document. Any Web-based simulation or statistical application that needs generation of random variates, their scatter plots and histograms, can invoke the RVG Web service programmatically at http://sunfish.cs.vt.edu/RVGWebService . / Master of Science

如同硬體元件的模組化，軟體元件的模組化在應用系統開發領域也取得的普遍的認知。以Web為基礎的應用系統在分散式運算環境中日趨重要。美國昇陽公司開發Servlet & JSP技術來作為網際網路應用系統開發的工具。在本研究中採用 Model-View-Controller架構，就網際網路應用系統開發中的模組化趨勢透過使用 Servlet & JSP技術來加以檢驗。為了實作的需要，採用了農民曆法轉換程式來作為處理Model部份之運算邏輯。最後並自然導引出從系統開發過成中合理有效之人力資源配置原則。 / Just like the modularization of hardware component, the trend of modularization of software component has gained also general recognition in the field of application system development. Recently, web-based application has become more and more important in the distributed computing environment. The Sun Inc. has been developing the servlet & JSP technology to be used for developing interactive web application. In this research, a software component study following the model-view-Controller architecture is inspected to verify the software modularization trend in the web application development using servlet & JSP technology. For implementation purpose, a business logic dealing with Chinese Calendar Transformation is selected as the model part. The implication of human resource allocation from point of view the application system development is also outlined as a deductive conclusion.

Every software program that interacts with a user requires a user interface. Model-View-Controller (MVC) is a common design pattern to integrate a user interface with the application domain logic. MVC separates the representation of the application domain (Model) from the display of the application's state (View) and user interaction control (Controller). However, studying the literature reveals that a variety of other related patterns exists, which we denote with Model-View-* (MV*) design patterns. This thesis discusses existing MV* patterns classified in three main families: Model-View-Controller (MVC), Model-View-View Model (MVVM), and Model-View-Presenter (MVP). We take a practitioners' point of view and emphasize the essentials of each family as well as the differences. The study shows that the selection of patterns should take into account the use cases and quality requirements at hand, and chosen technology. We illustrate the selection of a pattern with an example of our practice. The study results aim to bring more clarity in the variety of MV* design patterns and help practitioners to make better grounded decisions when selecting patterns.

The work discusses the analysis, proposal and implementation of simplified outpatient information system of general practitioner (GP), which communicates with IZIP information system. The proposal of system uses the Model-View-Controller architecture; the design patterns and subject simulated technique use UML. The way of communication with IZIP system, the structure of sent data and the communication security is also described in the work. C++ programming language is used for the implementation of the proposed system, parser Xerces-C++ for XML documents processing, toolkit Qt for graphical user's interface; and the data are stored into the Firebird relational database.

The report analyses if some common problems can be avoided by using modern technology. As a reference system “Fartygsrapporteringssystemet” is used. It is an n-tier web application built with modern technology at time, 2003-2004. The aim is to examine whether ASP.Net MVC, Windows Communication Foundation, Workflow Foundation and SQL Server 2005 Service Broker can be used to create an n-tier web application which also communicate with other systems and facilitate automated testing. The report describes the construction of a prototype in which the presentation layer uses ASP.Net MVC to separate presentation and business logic. Communication with the business layer is done through the Windows Communication Foundation. Hard coded processes are broken out and dealt with by Workflow Foundation. Asynchronous communication with other systems is done by using Microsoft SQL Server 2005 Service Broker. The results of the analysis is that these techniques can be used to create a n-tier web application, but that ASP.Net MVC, which at present only available in a preview release, is not sufficiently developed yet.

Joomla! ist eines der beliebtesten Open Source Web Content Management Systeme. Seine Popularität verdankt das System vor allem den vielfältigen Möglichkeiten zur Anpassung der Applikation an die individuellen Bedürfnisse der Nutzer unter Anwendung zahlreicher Erweiterungen. Mit Einführung der Version 1.5 wurde jedoch ein nahezu vollständig überarbeitetes System veröffentlicht, welches nunmehr einen durchgehend objektorientierten Ansatz verfolgt und Erweiterungen entsprechend der Model-View-Controller Architektur umsetzt. Dies hat zur Folge, dass eine Vielzahl bereits bestehender Erweiterungen nicht mit Joomla! 1.5 kompatibel sind. So auch die Newsletter-Komponente MkPostman 1.6 Beta des Chemnitzer Unternehmens „das Medienkombinat“. Die Firma stellte daher die Aufgabe, die Erweiterung im Rahmen einer Masterarbeit auf Basis des bestehenden Newsletter-Systems an das neue Joomla!-Framework anzupassen. Das Hauptaugenmerk lag dabei auf der Implementierung der überarbeiteten Erweiterung. Die vorliegende Ausarbeitung erläutert jedoch weniger die technischen Details dieser Umsetzung, sondern stellt die theoretischen Überlegungen und damit den Hintergrund der Entstehung des neuen Newsletter-Systems in den Mittelpunkt. So versucht sie zunächst ein Verständnis für das Potential, aber auch die Anforderungen eines Newsletter-System aufzubauen, indem wichtige ökonomische, rechtliche und technische Aspekte betrachtet werden. Im Zuge dessen wird näher auf den Begriff des Newsletters eingegangen. Weiterhin ist eine kurze Einführung in das Gebiet des Content Managements essentiell, um aufzuzeigen, worin dessen Idee liegt und wie diese mit Hilfe von Software umgesetzt werden kann. Dabei werden nicht nur der allgemeine Aufbau und die Funktionalitäten eines Content Management Systems genauer in Augenschein genommen, sondern vor allem das Open Source Web Content Management System Joomla! kurz vorgestellt. Um eine genauere Vorstellung davon zu bekommen, welche Mindestanforderungen an die neu zu entwickelnde Newsletter-Anwendung gestellt werden, folgt eine Untersuchung der aktuellen Komponente MkPostman 1.6 Beta hinsichtlich ihres Funktionsumfangs und ihrer Beschaffenheit. Ferner werden die Ergebnisse einer Beurteilung der Gebrauchstauglichkeit des Systems aus Sicht der derzeitigen Anwender präsentiert und die Erfordernisse der Nutzer an die neu zu entwickelnde Erweiterung ermittelt. Basierend auf den bis dahin getätigten Erkenntnissen erfolgt schließlich die Konzeption des neuen Newsletter-Systems, welches sowohl bereits bestehende als auch neue Elemente integriert. Dabei werden in erster Linie der anvisierte Aufbau sowie einige wichtige Funktionalitäten dargestellt. Schlussendlich wird kurz erläutert, wie die geplanten Grundfunktionen umgesetzt wurden und welche Möglichkeiten sich im Zuge einer Weiterentwicklung des entstandenen Systems ergaben.

This thesis aims to investigate the theory, processes and implementation details behind the development of a web application purposed to validate and import customer data into Ipendo Platform, an online web portal for managing intellectual property (IP) rights. Ipendo Systems, the company behind Ipendo Platform, required a solution that could improve efficiency and reliability over their current script-based validation and import process. The software produced during this thesis only partly solves the problems of current import methods by providing a tool for importing a specific type of customer data. It does however provide the infrastructure for the validation and importation of other types of customer data (platform objects). These extensions would however require more time than allocated for this thesis. The development has taken place over a period of ten weeks during which several decisions has been made regarding areas such as the chosen development process, system architecture and more concrete implementation details of the software’s different functionality. These decisions will be discussed and motivated with the help of referenced development theory, examples and figures. The delivered solution successfully validates and imports the supported platform objects, while providing an interactive user interface for the user to work within. It also provides architecture ready for extension with new validations and import modules for all types of platform objects. Finally, the results obtained with the developed tool points to a large increase in efficiency for the supported platform object.

The subject of this thesis was agile development on ASP.NET web development platform. The main goal was to create new methodology MMSP - ASP.NET MVC by adjusting methodology MMSP for development in ASP.NET MVC framework, which was mainly achieved through the definition of new objects in the methodology. Text describes four newly created roles (eg. Database specialist) which are responsible for application development. Text also defines or modifies several tasks (eg. Database design) and work products (eg. Data model). All added objects were integrated into the methodology by adjusting its life cycle. At first, thesis was generally focused on the development of web applications, defined their characteristics and analyzed the possibilities of using agile development. Then the MMSP methodology was presented and verified its suitability for the planned extension. Furthermore, there was described the ASP.NET MVC framework, its architecture and basic characteristics. In the last chapter of this thesis methodology MMSP-ASP.NET MVC was verified on the example of development database management web application for the Anthropological Department of the National Museum in Prague.

The aim of this master thesis is to propose a system for monitoring and regulation the climate in groups of terrariums using Raspberry Pi platform and with subsequent well-arranged representation through the web server. Each group of terrariums has its own measure and regulation device Arduino NANO that wirelessly communicates with central computer Raspberry Pi. The measured values are stored in the MySQL database in central computer. These values are then graphically displayed on the web page. Limit values for regulation and regulation times can also be set through web page.
