USB-minnen är ett portabelt lagringsmedium som går att hitta nästan överallt i dags-läget. Dessa enheter gör det möjligt att lätt spara filer och flytta dem till andra platser. Studien har som syfte att undersöka hur personal på kommunkontor i mindre kom-muner inom Skaraborg använder USB-minnen. Mindre kommuner har det ofta svårtatt anställa kvalificerad personal samt att få ekonomin att gå ihop. Trotts detta för-utsätts att de fortfarande följer samma lagar och utför samma uppgifter som störrekommuner. För att nå ut till kommuner baserades urvalet på medlemskommunernai Skaraborg kommunalförbund, av dessa kommuner uppfyllde tio kommuner kravetpå att vara en mindre kommun.Personalen fick sedan besvara en enkät om USB-minnen. Totalt inkom 30 unika svarfrån 7 olika kommuner.Svaren analyserades sedan och visar på att: Personalen är medvetna vad USB-minnen är och de tillåts använda dessa på kontoren.Enbart en dryg tredjedel hade fått information om hur de skulle hantera USB-minnen.Användningen skiljde sig mellan personalen en dryg tredjedel uppgav att de användeUSB-minnen för att lagra filer, likaså flytta filer. En dryg tredjedel uppgav att de hadetagit med sig USB-minnen utanför arbetsplatsen. Oberoende av användningsområdetär presentationer den vanligaste filtypen på USB-minnet.

Today the Sjöbjörn studio has a mixing console controlled by a PC with outdated software and hardware technology. The hardware requires an ISA-bus to work at all and thereby limits the upgrades that can be made to the computer. The software runs in a DOS environment and has not been updated for a long time as well. This makes working with the mixing console more difficult then it has to be and new features are hard to implement. In this thesis I have developed new hardware so that a more powerful computer can be used which hopefully will allow for a more user friendly interface and make it easier for future upgrades and additions. The thesis presents a solution on how to upgrade the system all the way from the PCcommunication to the hardware designs. The project was based around the Microchip PIC18F4550 microcontroller for the hardware and the Visual Basic.NET programming language for the PC software.

The work deals with building controlling system. It can be divided into three parts. First part describe general theory of smart houses. Second part analysing the task. Last part is realization about.

This thesis is focused on entropy sources and their evaluation. It includes a brief introduction to the information theory, description of entropy sources, their parameters and characteristics and methods of evaluation based on the NIST organisation standard SP 800-90B. The following part of the thesis is dedicated to the description of two created programs and evaluation and comparison of entropy sources. Additionally, the last part describes the usage of hash functions in association with entropy sources.

Táto diplomová práca sa zaoberá návrhom a realizáciou výukového modelu pre študentov mechatroniky na vysokej škole. Úvod práce sa zaoberá krátkym uvedením do problematiky používania univerzálnej sériovej zbernice a jej implementáciou pre komunikáciu s mikrokontrolérom. Druhá časť je venovaná hardwaru zariadenia, medzi čo patrí voľba vhodného motoru, návrh vhodných elektronických komponentov, návrh dosiek plošných spojov a taktiež mechanickej konštrukcie celého zariadenia. Nasleduje softwarová časť, popisujúca praktickú realizáciu komunikácie, program v mikrokontroléry, a Toolbox, ktorý umožňuje užívateľovi jednoduchú interakciu s hardwarom a to jak z Matlabu. tak zo Simulinku. Kombinácia navrhnutých hardwarových a softwarových prvkov umožňuje jednoduchú cestu k zlepšeniu vedomostí študentov v oblastiach programovania, riadenia a modelovaní sústav. Pre tieto účely je práca rozšírená o pracovný list, ktorý dopĺňa navrhnuté zariadenie o sadu experimentálnych úloh, zameraných na vybrané mechatronické problémy.

This master's thesis deals with design electronics for an antenna rotator in two axis. There are designed and implemented drivers for two stepper motors. Was also designed and implemented control panel that allows manual control the rotator and remote control by PC via USB. At the same time created software for control panel and PC application for easy operation.

The purpose of this thesis is to design FSK modem for Packet communication. In accordance with accessible literature was constructed functioning circuit schema and subsequently there was constructed a motherboard which is mainly assembled from SMD technology. It makes this modem mobile and very easy usable in terrain. Modem communicates with PC via USB bus. Also this bus is used as power source for this device. Communication between modem and PC is realized by KISS protocol and connection with tranciever is realized by AX.25 protocol.

This work deals with design and construction logger capable measure temperature and relative humidity value and save them. Work also solution maximize batery life and number of record storaged in bulit-in flash memory.

The work deals with building controlling system. It can be divided into three parts. First part describe general theory of smart houses. Second part analysing the task. Last part is realization about.

The thesis goal was introduce with 32-bit microcontrollers produced by ATMEL, synchronous digital interface and implementation USB protocol in MCU. On base of this informations design device which have behaviour as USB audio with fully variable parameters and digital output in I2S format.
