61	Tvorba znalostní databáze pro světelnou techniku s možností expertního zpracování dotazů / Creation of Knowledge Database for Lighting Technology with the Possibility of Expert Query Processing Krbal, Michal January 2014 (has links) This presented thesis is focused on the complex description of creation the database system for the lighting. The important static and dynamic parameters of light sources and luminaires are listed in the first part of thesis. These parameters are complemented by the measured values and their relationships. The next chapters of thesis are focused to description of obtained parameters, structural design, historical and expected development of individual representatives of light sources. In the following sections are described current state of used data formats of luminaires and the possibilities for describing of light sources. The database systems are created as a result of this thesis. These databases are used for collecting, sorting, searching and sophisticate comparison of the parameters of light sources and luminaires.
62	Energy-Efficient In-Memory Database Computing Lehner, Wolfgang January 2013 (has links) The efficient and flexible management of large datasets is one of the core requirements of modern business applications. Having access to consistent and up-to-date information is the foundation for operational, tactical, and strategic decision making. Within the last few years, the database community sparked a large number of extremely innovative research projects to push the envelope in the context of modern database system architectures. In this paper, we outline requirements and influencing factors to identify some of the hot research topics in database management systems. We argue that—even after 30 years of active database research—the time is right to rethink some of the core architectural principles and come up with novel approaches to meet the requirements of the next decades in data management. The sheer number of diverse and novel (e.g., scientific) application areas, the existence of modern hardware capabilities, and the need of large data centers to become more energy-efficient will be the drivers for database research in the years to come. info:eu-repo/classification/ddc/004 ddc:004
63	Usability guided development of a participant database system / Användbarhetsledd utveckling av ett deltagardatabassystem Falk, Joakim January 2018 (has links) This project consisted of the development of a web based participant database system to replace a spreadsheet based one for the project “Vi Ses! Språkvänner i Linköping” and the evaluation of it. The design and implementation was done iteratively using a collection of usability guidelines as well as the results of a set of user tests. User tests were also used for the evaluation of the web database system. The task during the user tests was participant matching and the main measurement taken was task completion time. The project resulted in a web database system that could fully replace the spreadsheet database system. The evaluation tests showed that this system was both faster to match participants in as well as less error prone. / Detta projekt bestod av utvecklingen och evalueringen av ett webbaserat databassystem för deltagare. Den skulle ersätta ett existerande Excel-baserat databassystem för projektet “Vi Ses! Språkvänner i Linköping”. Designen och implementationen gjordes iterativt med hjälp av användbarhetsriktlinjer och resultat från användartester. Användartester användes även för evalueringen av webbdatabassystemet. Uppgiften i användartesterna var deltagarmatchning och det huvudsakliga mätvärdet var hur lång tid uppgiften tog. Projektet resulterade i ett webbaserat databassystem som helt kunde ersätta det Excel-baserade systemet. Evalueringstesterna visade att systemet var både snabbare och mindre felbenäget att matcha deltagare i.

64	Řízení dodávky vody v rodinném domě / Control of water supply for a house Chvátal, Michal January 2021 (has links) The diploma thesis deals with the design and implementation of the system that will control the water supply for the family house and its garden. The system aslo allows you to store a history that can be viewed via the web interface. The web interface also allows you to set system parameters and monitor the current status.
