Principles of an automatic brewing machine : By using CodeSys with Raspberry Pi / Principer för ett automatiskt ölbryggeri : genom användning av CodeSys och Raspberry Pi

Mårtensson, Daniel January 2017 (has links)
This project will give you a view from another side when it comes to control engineering and mechanical construction in brewing. This is a thesis project about principles for an automatic brewing machine. This project started off with prestudy of earlier research results in automatic brewing based on the Arduino platform. This project shows principles about mechanical construction and creating a control system by using inexpensive commercial products such as CodeSys and Raspberry Pi. The project report begins describing the mechanical construction, how it works and it shows how it looks. The mechanical construction is a tall scaffolding which is the chassis of the brewing machine. The history background about brewing is reviewed and the fundamental methods about brewing are described as well. The goal of this project is to present principals by using CodeSys and Raspberry Pi together. Notice that this is not a construction document. This document does not include production wiring diagrams or blueprints – only principles of wiring diagrams and figures of the machine, designed in a CAD software. This brewing machine includes a few different kind of control systems to automate the process. The processes are a hops container that can deliver a set of hops in a specific time, motorized whisks to distribute the heat, heat exchanger for cooling down, heating control system and a drain control system. The main focus in this project is the mechanical parts, the flow system, the control systems and a discussion about each sub system. Results shows a lot of pictures of the complete system with text that explain the pictures. What was good, what was bad and what could be done better.

Den konfliktlöse udvikling?

Mildh, Esbjörn January 2011 (has links)
Formål: Læring og udvikling i arbejdslivet betragtes alment som positivt for individet når de beskrives i de dominerende læringsteorier. Denne artikel retter et kritisk blik på dette område ved at belyse og udforske vilkår og krav om udvikling, som møder ansatte i en vidensintensiv virksomhed.   Studiets design, metode og tilgang: Artiklen er baseret på kvalitativt design med åbne metoder, indeholdende interviews af både ansatte og ledelse, indsamling af skriftlige materialer samt deltagelse i virksomhedens konferencer. Analyserne er foretaget ud fra en naturalistisk tilgang.   Resultat: Det fremkommer, at den centrale styring her, udgøres af en strategi baseret på et normativt og ideologisk ideal om at være udviklingsorienteret, som de ansatte ikke blot må acceptere, men selv være en aktiv del af. Artiklen diskuterer afslutningsvis om en sådan strategi kun kan være gældende i særlige typer af organisationer, eller om hvorvidt strategien kan ses i en bredere del af arbejdslivet.   Originalitet og værdi: Gennem en analyse af læringsprocesser, identitetsudvikling og anvendte ledelsesstrategier, argumenteres der i denne artikel for, at læring og udviklingsprocesser kan forstås som vigtig del af kontrollen over ansatte i post-bureaukratiske organisationer.

Komunikace, rodičovská kontrola a gender rozdíly v rodičovských stylech a jejich vliv na užívání alkoholu u žáků šestých tříd zapojených do projektu Unplugged / Communication, parental control, and gender differences in parenting styles and their effect on alcohol use among sixth grade students involved in the project Unplugged

Stará, Iveta January 2015 (has links)
BACKGROUND: Foreign studies shown, that parenting style and specific aspects of parenting has effect to children in alcohol consumption. In family style, with minimum alcohol consumption were children from families who enforced authoritative parenting style, also in families where parents communicate with children, give them clear boundaries and control them. AIMS: The aim of the research part of the thesis is to investigate the relationship between communication style, selected aspects of parenting style (such as control and following rules) in the family and alcohol use among children. Another theme of the thesis is also to determine the differences between girls and boys in the prevalence of alcohol use, depending on the researched communication aspects and parenting style. METHODS: To obtain the data was used the questionnaire European Family Empowerment Questionnaire (Sumnal, Calafat, 2010). The questionnaire was translated to Czech language. This questionnaire was filled by children and also one of their parents. Only selected questions from survey were used for research project. Beside of the social demographic data and information about the prevalence of consumption of alcohol another two questions about the parenting aspects (control and communication) were chosen. Data from parents and...

Flight Simulation And Control Of A Helicopter

Ercin, Gulsum Hilal 01 December 2008 (has links) (PDF)
In this thesis the development of a nonlinear simulation model of a utility helicopter and the design of its automatic flight control system is addressed. In the first part of this thesis, the nonlinear dynamic model for a full size helicopter is developed using the MATLAB/SIMULINK environment. The main rotor (composed of inflow and flapping dynamics parts), tail rotor, fuselage, vertical stabilizer, horizontal stabilizer of the helicopter are modeled in order to obtain the total forces and moments needed for the flight simulation of the helicopter. Total forces and moments are used in 6 degrees of freedom equations of motion model and helicopter states are calculated for the specified flight conditions such as hover and forward flight. Trim and linearization programs are developed. The linearized models of hover and forward flight conditions are used for the automatic flight control system design. Automatic flight control system model consists of necessary systems in order to ease the pilot control of the helicopter. A classical inner stability loop and outer flight directory mode approach is taken to design the automatic flight control system. For the inner stability loop both classical rate feedback and truncated system state feedback control approaches are used. The outer loop modes implemented are heading hold, attitude hold (pitch, roll), altitude acquire and hold mode for hover condition and heading hold, attitude hold (pitch, roll), altitude acquire and hold mode and airspeed hold for forward flight condition. Finally, the success of the controllers are demonstrated through nonlinear simulations for different flight directory modes in hover and forward flight conditions.

Řízení vytápění rodinného domu / Control of house heating

Hnyk, Marek January 2016 (has links)
The aim of the final thesis is a proposal and implementation of a system which would enable a heating control on the basis of data gathered by monitoring of particular rooms inside a building. In particular, it is focused on water measurement within the heating system, TUV (non-potable hot water) and the temperature within the space of residential rooms. The system headquarters must enable an automated saving of the measured data. Selected temperature figures will be made accessible by a web interface and continuously saved on the web server.

Dopad kurzového závazku ČNB na český export / The impact of CNB's exchange rate commitment on Czech exports

Teichman, Jiří January 2019 (has links)
The thesis evaluates the effect of Czech National Bank's exchange rate commit- ment on Czech sectoral exports. Thus, we show how unconventional monetary policies could affect the exports. To assess the impact of interventions, we use Synthetic Control Method. The method constructs synthetic Czech exports from data of comparable countries that were not under the policy of inter- est and compares them to observed Czech exports following the interventions. We expect a positive effect of Czech National Bank's commitment on Czech exports, because the interventions resulted in the undervaluation of koruna causing a higher demand for Czech goods abroad. Additionally, the exporters should benefit from reduced uncertainty caused by no exchange rate volatility with the euro area. The results showed a positive impact of interventions only in half of the export sectors. The positive effect of a stable exchange rate is not confirmed, because the effect on the euro area countries in some categories was smaller than for the other countries. The results for total sectoral exports were stable across model specifications and confirmed by analysis of Czech bi- lateral sectoral exports to the largest destinations. The significant contribution of this thesis is application of Synthetic Control Method on total sectoral...
