1	Automatisk differentiering av randintegrallösare för PDE-villkorad formoptimering Johansson, Rebecka, Stensson, Asta January 2024 (has links) För många vetenskapliga och ingenjörsmässiga problem är det intressant att hitta en optimal geometri. Den typen av optimeringsproblem kallas formoptimering. Särskilt vanligt är det att vilja lösa formoptimeringsproblem med en partiell differentialekvation som bivillkor, det vill säga formoptimeringsproblem vars målfunktion beror på lösningen till en PDE. På senare tid har framsteg inom automatisk differentiering gjort det möjligt att diskretisera problem innan de differentieras, vilket möjliggör nya numeriska lösningsmetoder av optimeringsproblem. Det här projektet ämnar till att formulera en metod för att numeriskt lösa PDE-villkorade formoptimeringsproblem med automatisk differentiering och gradientstegning med hjälp av kodbiblioteket JAX i Python. Dessutom genomförs en dimensionsreduktion genom randintegralmetoder för PDE. Metoden testas på ett enkelt problem som inte innehåller någon PDE, och ett svårare problem där Poissons ekvationer ges som bivillkor. För snälla problem och startgeometrier uppnås snabbt ett litet fel. Om initialiseringsgeometrin är för långt ifrån optimum är konvergensen stort beroende av antal diskretiseringspunkter. För svårare problem utan känd lösning är det svårt att utvärdera resultatet. Något som är svårt att motverka är injektivitetsproblem vilket behövs undersökas vidare.

3	Webový systém pro správu GPS dat v cloudovém prostředí / Web-Based GPS Data Management System in a Cloud Environment Kasala, Viliam January 2015 (has links) This thesis focuses on development of web-based GPS data management system in a cloud environment. The thesis introduces the most used application interfaces for building custom mapping applications. It offers a comparison of cloud platforms such as Google App Engine and OpenShift Online. It also deals with the design and the implementation of system for OpenShift Online platform. The system focuses on importing tracks from GPX format, managing tracks, viewing tracks on map tiles from Mapy.cz, searching for tracks, creating an elevation profile and various statistics.
4	Geografický informační systém pro pasportizaci a vizualizaci rozlehlých počítačových sítí / GEO Information System for Passportization and Visualization of Wide Computer Networks Fibich, Ondřej January 2014 (has links) The thesis is focused on the problem of the passportization and the visualization of wide computer networks with the usage of geographic information systems. It discusses principals and properties of geographic information systems and spatial databases that are frequently used as data carriers for geographic information systems. The main part of the thesis is dedicated to the passportization of computer networks with focusing on the physical network structure. After the definition of the passport format the thesis continues with the analysis, the proposal, the implementation and the testing of the geographic information system for managing and visualization of the passport in this format. The thesis is ended by a case study that demonstrates the passportization process of an access computer network in the implemented system.
5	License Management for EBITool Krznaric, Anton January 2013 (has links) This degree project deals with license management for EBITool. It´s about providing protection and monitoring for a Java Application via a license server, and the construction of it. An analysis that discusses the approach and other possible courses of action is also included. Additionally, it covers a discussion of a prototype implementation of the model solution from the analysis. The prototype is a Java EE application that deploys to JBoss AS7. It´s developed using the JBoss Developer Studio 5.0.0, an Eclipse IDE with JBoss Tools preinstalled. It exposes web services to Java Applications through SOAP via JAX-WS. Using Hibernate, the web service Enterprise Java Beans get access to a PostgreSQL 9.1 database via entity classes mapped to the database through the Java Persistence API.

6	Webová aplikace zprostředkovávající výsledky testování výkonu platformy JBoss / Test Result Repository with Web User Interface Vlasák, Jaroslav January 2013 (has links) This thesis deals with the development of a client-server application for Red Hat company. Client participates in testing process of JBoss platform and gets user-defined performance data which sends during testing to the server application by platform independent communication. The server application allows to analyze the received data which can be also compared by several perspectives. These services for data analysis and comparison are accessible for server users using the web client. The server application supports the import of the performance data stored in the XML file and also their export for qVue portal. The client part of the application is implemented in Java and the server application is based on Java EE platform.
