Analýza frekvenčního naladění lopatek oběžného kola parní turbíny / Frequency analysis of the blades of the steam turbine impeller

Krejčí, Jaroslav January 2015 (has links)
The master thesis deals with modal analysis of the blade of the steam turbine impeller. This analysis is made to find the frequency response of the blade in order to predict the dangerous speeds of the steam turbine. At first the problem situation is described. Than follows the research study which is focused on steam turbines and especially on the rotor dynamic systems and the way to ascertain the modal parameters of the dynamic system by experiment. After that the solution of the problem is performed by computational modelling. The results of the computation are analyzed in detail for different variations of the blade length by Campbell diagram. A graph showing dependency between dangerous speeds of the turbine and the blade length is made out of the results. Then the results are verified by experiment and the coefficients of proportional damping are specified. In conclusion the optimal variation of the blade length for the given operational state is determined.

Simulátor Turingových strojů popsaných pomocí kompozitních diagramů / Simulator of Turing Machines Described by Means of Composite Diagrams

Siska, Josef January 2014 (has links)
In this thesis, the theory related to Turing machines and means of their description (with focus on composite diagrams) is presented. The aim of this work is to create an application that allows editing Turing machines described by means of composite diagrams and simulating their computation on specified input configuration (including non-deterministic and multi-tape machines). Furthermore, within the application it will be possible to run the termination analysis of Turing machine in order to determine whether this machine or any of its parts always halt. The resulting application is implemented in Java and the termination analysis is performed using the well-founded orders. And so, one of the results created during this work is a software tool which allows designing and testing of Turing machines described by means of composite diagrams. Resulting application may be used especially during lectures on theoretical computer science, where it can be used to demonstrate computation of some Turing machine.

Explorativní editace zdrojových textů / Explorative Source Code Editor

Šomlo, Ivan January 2011 (has links)
The thesis discusses the tools commonly used by developers in exploratory environments of languages Smalltalk and Self. These languages free their users from using plain unstructured source code. Moreover, they contain tools with richer features. The thesis consists of an analysis, a design proposal, and a description of Object Viewer, a Self based tool designed for languages C and C++. The tool graphically displays fragments of a program (objects and pointers) and allows for manipulating them during debugging. The conclusion consists of a summary and a recommendation for additional new features.

Jak nově myslet architekturu. Pozdní myšlení Petera Eisenmana a jeho kritická teorie architektury / How to think Architecture in a new way. Late though of Peter Eisenman and his critical theory of architecture

Tourek, Jiří January 2014 (has links)
Dissertation thesis "How to think Architecture in a new way. Late though of Peter Eisenman and his critical theory of architecture" tries to summarise and analyse the key thoughts of architect and thinker Peter Eisenman in his late oeuvre. The point of departure of his theoretical thinking seems to be refusal of any timeless essence of architecture and a will to "dislocate" architecture from influence of metaphysics. The way to this is "criticality", a notion constituted with three basic terms: interiority (the interiority of architecture defines the discipline, what it is that makes architecture singular), exteriority (external concepts that change architecture by being internalised into the discipline and changing it) and anteriority (anteriority is the sedimented history of architecture; history of interiority). These three terms are according to Eisenman connected in a notion of "undecidability" that serves as a central criterium to criticality and in a "diagram" that is a mean to overcome metaphysical implications of architecture. At the end of the thesis there is a summary of Eisenman's theoretical work and its importance and an attempt is made to set so conceived whole in its entirety to the thought of "end of metaphysics". In this context is Eisenman seen to be in a position similar from...

Test management in a PLM system context

González Corona, Alicia, Melle, Daniel January 2023 (has links)
The purpose of this final project work is to explore how tests are managed during the development of mechatronic products at a manufacturing company. This study aims to develop an information model and a process model that can be used in a PLM system. The research method used is a case study at Husqvarna Group. The different test departments in the Huskvarna site are studied. For that, two rounds of semistructured interviews and document studies are conducted to collect primary and secondary data. For each round, six interviews are conducted with experienced employees and then, a verification meeting is held. During the qualitative analysis, different keywords are highlighted and displayed in an activity and class diagram to represent the as-is test management process at the case company. Later, it is compared to the literature, and a proposal is made based on the results.

Aplikace objektových metod v návrhu informačního systému platební instituce / Application of object-oriented methodology when designing an information system of the payment institution

Justová, Markéta January 2015 (has links)
The aim of the Diploma thesis is to evaluate the selected object-oriented (OO) methodology as it was defined by its author, on the basis of defined criteria, whether it is applicable in practice when designing an information system, with a main focus on analysis of the new core banking system supporting key processes of payment institution and Forex broker. Diploma thesis describes selected OO methodologies and notations used in the analysis and design of information systems. Further, it focuses on the evaluation of the real usage of selected method (Unified Process) in the environment of payment institution. It confronts the theoretical definition of a selected OO methodology with its application during the analysis of IS through practical demonstrations created within the case study.

La propuesta de mejora continua tuvo como objetivos: reducir los tiempos de entrega del producto final del proceso de ensamblaje; analizar, identificar y mejorar las demoras en los tiempos de operación, proponer una adecuada distribución de planta y minimizar las fallas de las máquinas. Además, se utilizó técnicas de ingeniería, como por ejemplo; diagrama de actividades, diagrama de flujo, diagrama de recorrido. También el estudio de tiempo es fundamental para establecer los tiempos necesarios para cada operación. Con estos métodos y herramientas de ingeniería se logró cumplir con el tiempo de entrega de los productos ensamblados y tener una distribución de planta ordenada que permitió una mayor fluidez de los operarios y del producto. Como resultado más importante se obtuvo un aumento en la productividad de 52%, consiguiendo reducir el tiempo de entrega del producto. Por consiguiente, aumentando la satisfacción del cliente. The following thesis seeks to analyze and apply productivity tools, in order to improve the assembly process of hydraulic hoses in the Company Contix S.A. The improvement proposal continue aims to reduce the delivery time of the final product of the assembly process; analyze, identify and improve the delays in the operation times. To propose an appropriate distribution of plant and to minimize the machines’ failures. In addition, engineering techniques will be used, such as; Activity Diagram (UML), Flow Diagram (or Flowchart), Circuit Diagram. It is also crucial the Study of time for determining the time required for each operation. These methods and engineering tools will allow to comply with the assembled products’ delivery time and also have an orderly distribution plant allowing greater fluidity of operators and product. As the most important result, an improved productivity of 52% will be achieved, reducing the delivery time of the product. As a result, the increase of customer satisfaction.
