Možnosti osvětlení vozidel pro zvýšení bezpečnosti silničního provozu / Possibilities of Vehicle Lighting to Increase Road Transport Safety

Balharová, Gabriela January 2012 (has links)
This master’s thesis deals with the possibilities of illumination of motor vehicles. Thesis is divided into two sections, from which the first discusses precisely the possibilities of lighting of motor vehicles at the present time. What are the modern lighting techniques, that can be found on the market and what is their impact on safety enhancement in road traffic. Second section is about the practical measurement of low and high beam afterglow. This measurement is being compared between two types of headlamps, namely halogen headlights and xenon headlights. Part of the measurement is as well measurement of illumination intensity precisely for these headlights. The output of measurement is the creation of own illumination intensity diagrams and afterglow diagrams of particular headlights, in comparison to isolux diagrams provided by the headlights manufacturer. Consequently are solved the issues about utilization of the isolux diagrams in expert praxis.

BezpeÄnost obrbÄc­ch stroj / Machine tools safety

Smetana,  tÄpn January 2016 (has links)
This Masterâs thesis concerns about the safety of machinery, in the literary research part you can find information about the law system and requirements of European Union and Czech Republic. There is a description of the legal enactments, which the manufacturers of machinery needs to follow. Second part of this thesis is about the safety of a milling center. The milling center is analyzed here, you can find here the description of its components. The milling center was then described with the help of block diagrams. For each component from the block diagram you can find here a list of dangerous situations which can occur and also a list of safety precautions for each situation. Based on these information the list of requirements for the milling center was made.

Konečné prvky v elektromagnetismu kompatibilní s De Rhamovým diagramem / Konečné prvky v elektromagnetismu kompatibilní s De Rhamovým diagramem

Rybář, Vojtěch January 2011 (has links)
Title: Finite elements for electromagnetics compatible with de Rham di- agram Author: Vojtěch Rybář Department: Department of Numerical Mathematics Supervisor: prof. Ing. Ivo Doležel, CSc. Abstract: The present work is devoted to the lowest-order finite elements for solving time-harmonic Maxwell's equations in two dimensions. Suc- cessful approximation of these equations requires the finite element spaces to be compatible with the de Rham diagram. However, the most often used basis functions (the Whitney functions) do not comply with this diagram. Therefore, we construct compatible bases and study their prop- erties. Since the construction is not unique, we investigate the influence of the particular choice on the conditioning of the corresponding finite element matrices. Finally, we utilize the special structure of the stiffness matrices, propose a few iterative schemes, and compare their convergence. Keywords: Maxwell's equations, edge finite element, de Rham diagram, finite element basis 1

Verktyg för kvalitetsutveckling

Amin, rebin January 2020 (has links)
Verktyg för kvalitetsutveckling är en del av offensiv kvalitetsutveckling. Bland dessa verktygsuppsättningar återfinns de sju ledningsverktygen och de sju förbättringsverktygen. Verktygen hjälper bland annat till att förstå, förklara och stödja beslutsfattandet med hänsyn till att en viktig hörnsten i kvalitetsutveckling grundar sig på att basera beslut på fakta.Denna studie bygger på en systematiserad litteraturöversikt och undersöker hur de sju ledningsverktygen och ishikawa-diagrammet använts och vilka ämnen dessa analyserar inom olika branscher. Detta i syfte att bredda kunskapen kring dessa verktyg.Denna studie bidrar till att verksamheter får det lättare att relatera till snarlika problem eller utmaningar och därigenom välja lämpliga verktyg för en framgångsrik analys.Resultatet visar och bekräftar teorins beskrivningar av verktygens styrkor men också en högre grad av flexibilitet i när det är applicerbart att använda ett visst sorts verktyg. De flesta verktygen användes under analysfasen och i kombination med brainstorming. Bland branscherna är sjukvården frekvent närvarande där verktygen används för processförbättringar. Vidare visar resultatet att verktygen lever och används i högsta grad i den moderna praktiken. / Tools for Quality development are part of Total Quality Management TQM. These toolsets include the seven new management tools and the seven improvement tools. The tools help, among other things, to understand, explain and support decision-making, given that an important cornerstone of quality development is based on basing decisions on facts.This study is based on a systematized literature review and examines how the seven new management tools and the ishikawa diagram have been used and what subjects have been analyzed in different industries. This is in order to broaden the knowledge of these tools.This study helps to make it easier for organizations to relate to similar problems or challenges and thereby choose the appropriate tools for successful analysis.The results show and confirm the theory's descriptions of the tools' strengths but also a higher degree of flexibility in when it is applicable to use a certain type of tool. Most of the tools were used during the analysis phase and in combination with brainstorming. Among the industries, healthcare is frequently present where the tools are used for process improvements. Furthermore, the results show that the tools are alive and are used to a great extent in modern practice. / <p>2020-06-26</p>

Statické řešení železobetonové konstrukce / Static solution of a reinforced concrete structure

Zedník, Tomáš Unknown Date (has links)
This diploma thesis deals with the design of a mountain hotel with a roof structure made of a reinforced concrete shell. During designing three types of design were assessed. The aim was to find out which of the design solutions is the most suitable for the behaviour of a reinforced concrete structure. The Dlubal RFEM program was used to assess and calculate the internal forces in the structure. In this thesis I also deal with the design and assessment of individual elements of the selected design solution. The thesis also includes drawings of construction plans and drawings of reinforcement plans.

Utredning av leveransprecisionen hos Företag X : En analys av in- och utgående logistik, inköp och produktion / Investigation of the delivery precision at Företag X : An analysis of inbound and outbound logistics, purchasing and production

Siggesson, Oskar, Hedendahl, Mattias January 2023 (has links)
Background: The company has had a low outgoing delivery precision for a prolonged period. This creates problems as orders must be prioritized in order to be produced on time and partial deliveries are used to satisfy customers. The origin of the problem is unknown to the company, but there are suspicions that the problems arise in production. Purpose: The purpose of the study is to contribute to an improved outgoing delivery precision for Företag X. A current state analysis from the inbound to the outbound flow is conducted to find causes of delays. The study creates a prioritization basis for the company to identify the most critical article groups. This creates a tool for decision support, linked to delivery precision, for manufacturing companies. Methods: This study is a case study at Företag X. The study uses secondary data in the form of quantitative data from the company's business system, but primary data in the form of interviews and the author’s own observations. The data is used to create a cause and effect diagram and to perform an ABC/XYZ-analysis on the company's inventory that forms the basis for segmentation of the articles. Conclusions: The study's conclusion is that Företag X's low outbound delivery precision is due to several reasons such as communication gaps, insufficient production planning and measurement &amp; variation in load. The most important cause is production planning. In order to improve this, other causes must also be solved first and Företag X must follow the priority order that the study has developed. Through this, Företag X can get a better outbound delivery precision and a more efficient flow. Keywords: Delivery precision, production planning, ABC/XYZ-analysis, classification, cause and effect diagram
