Plán řízení projektu; optimalizace a praktická aplikace / Project management plan; optimalization and practical application

Vrňák, Radek January 2009 (has links)
This thesis handles the issue of Project Management, especially formation and structuring of the plan of project control (Project Management Plan). Formation of the Project Management Plan is one of the activities, which is performed by project manager in cooperation with customer in the first phase of project life cycle. The content of this thesis is a proposal of optimised structure of Project Management Plan with predefined description and extent of individual parts (chapters). In addition, there are different methodologies and their comparison described in this thesis, which are usually used in Project Management. These are PMBOK, Prince2, ČSN ISO 10006 and the project methodology of Siemens, which is called Chestra. These methodologies form the base for a newly formed structure of Project Management Plan. In the supplement of this thesis, there is a template of the document Project Management Plan, with which a project manager is able to form a new management plan of particular project easily. This template was created on the basis of particular project analysis within the scope and work of Siemens IT Solutions and Services Company and reflects not only theoretical knowledge, but also the needs of the particular company.

Pevnostní návrh dvojice výměníků tepla / Structural design of heat exchanger pair

Pernica, Marek January 2017 (has links)
This master’s thesis deals with structural design of twin heat exchanger with vertically stacked horizontal vessels according to CSN EN 13 445 standard. Brief introduction and basic characteristics of shell and tube heat exchangers is performed in the beginning part of the thesis. Design of the heat exchanger was initially performed using design by formula (DBF), which was verified by specialized software Sant´Ambrogio. Since this approach does not include methods for assessment of the nonstandard connection between the vessels, simulations of significant load states were performed using FEM analyses followed by result evaluation using stress categories.

Návrh vysokotlakého výměníku tepla / Design of high-pressure heat exchanger

Marada, Petr January 2019 (has links)
The aim of the thesis is to design a heat exchanger for heating natural gas in the mining process and subsequent treatment. The first part describes natural gas itself, its origin, mining and ways of treatment. There are described technologies used for finding the deposits itself or processes by which water, sulfur and solid particles are removed from the extracted gas. The next section deals with the types of heat exchangers most commonly used in industry. There are also described basic relations for heat-hydraulic calculation of heat exchanger. In the practical part the heat exchanger itself was designed. World-wide HTRI software was used for the heat-hydraulic calculation and for strength calculation according to the standard ČSN EN 13445 was used sofware Sant´ Ambrogio.

Měřicí jednotka kvality elektrické energie / Measuring unit of electric power quality

Teplan, Miroslav January 2011 (has links)
This thesis describes the parameters of electrical energy with a focus on low voltage characteristics and their measurement with respect to the parameters required by standards. In addition, one chapter deals with monitoring of the quality electric energy. Measurement organizations, calculation of power quality and the data collection for its calculation is referred here. For the illustration, the example of a distributed monitoring system from practice is described. The second part deals with the design and implementation of a module for measuring power quality , namely by measuring the voltage characteristics. It describes the selection of the chosen solution, hardware part and firmware for the MCU. To display the measured data, application was created by the Java programming language. The application allows the visualization of the voltage measured Low voltage grid with single phase voltage RMS value 230.

Návrh na zlepšení systému řízení jakosti dle ČSN EN ISO 9001:2001 / Quality Management System Improvement according to ČSN EN ISO 9001:2001

Hájek, Jiří January 2009 (has links)
This thesis deals with a detailed analysis of the systems of quality management in a particular company according to EN ISO 9001:2000. The aim of this work is to analyse the system deeply and then focus on how the system could become more effective. In this case the topic was the system of measurement of the customers´satisfaction. In the theoretical part there is the overall view of quality from the historical point of view up to the present. For better understanding of the problem the principles of ISO standards, maintenance of the systems and improvement instruments are mentioned. In the practical part there is the analysis of the particular system of quality management and the process of application of improvement procedures.

Optimalizace vybraných návrhových prvků ČSN pro projektování pozemních komunikací / Optimization Of Selected Proposed ČSN Elements For Road Design

Kokeš, Ondřej January 2015 (has links)
Diploma thesis describes and researches some proposed ČSN 73 6101 elements for road design and their subsequent comparison with Norma de Traçado that is main law for road design in Portugal. In practical part, the speed of vehicles during moving on direction curves is researched and subsequently coherence of theoretical assumptions with real speeds is compared. The main aim of this work is to verify the assumption that design speed does not correspond to the real speed that drivers move on road structures.

Softwarová podpora návrhu a hodnocení výměníků tepla se svazkem trubek v plášti / Software Aided Design and Assessment of Shell and Tube Heat Exchangers

Létal, Tomáš Unknown Date (has links)
Subject of this work is a development of an integrated software environment for mechanical design and check of shell and tube heat exchangers. Processes of mechanical design and checks well as software which perform these processes are broken down to basic methods and parts. Mechanical design is usually performed according to some standards. In this work, ČSN EN 13445 is used. This standard describes mostly design check calculations which can be easily algorithmized. On the contrary, design calculations are described to some extent in few simple cases and mechanical design of shell and tube heat exchanger has not been fully algorithmized yet. Subject of this work is design of software, which will be capable of automatically performing mechanical design from datasheet as an input. Based on breakdown of design and check processes, requirements for key software features are derived. Important part of presented work is design and implementation of key modules – data model of shell and tube heat exchanger, module for mechanical design check according to ČSN EN 13445. These modules form basis of the software which will be developed further in future work.
