Dodávka informatických služeb - technologické a procesní zajištění dostupnosti a kontinuity služeb ve vazbě na podnikání a sjednané parametry služeb. / Information Service Delivery - IT Service Continuity Managment

Lipčák, Peter January 2009 (has links)
This thesis deals with the aspects of managing the business continuity by the methodologies of ITIL and Cobit. The main thesis objective is to find out if there exists one general aplicable solution of the business continuity managment process based on the relative approach comparison and integration of both methodologies and afterwards to define this general solution. The secondary thesis objective is to try to specify the problem issue, which is not covered neither one of those methodologies and then integrate it into this general solution. The purpose of first chapter is to analyze and generally describe the business continuity managment area, its relation with IT Service Managment, to define all key issue terms and to give a best practice review dealing with this field. In the following chapters there is a detailed look at the concrete individual approaches of metodics ITIL and Cobit to the area of business continuity managment. The final chapter deals with approach comparison of both methodologies based on by author defined key fields as target group, enterprise type, terminology, mature models, metrics, concept and relative mapping of relevant points. The chapter provides the general complex solution guideline of this issue by simultaneous implementation of both methodologies as well. This is the main contribution of this work. The next contribution consists in the definition of irrational employee behaviour problem during disaster and its integration to this general guidelines.

Problematika RTO a RPO v riadení kontinuity / The issue of RTO and RPO in business continuity management

Salai, Viktor January 2011 (has links)
This thesis is concerned about Business Continuity Management with the focus on determination of the RTO and RPO parameters. The work is divided into two main parts. The first section briefly describes theoretical issues of Business Continuity Management in conjunction with IT Service Continuity Management. Then there are described various technologies that are currently used to ensure continuity and recovery of IT systems. In conclusion of the theoretical part, the work focuses on the process of Business Impact Analysis. This thesis thus offers a comprehensive view of main principles and benefits that these concepts have for company and how they should be integrated with each other. It provides an overview of various technologies, their link to RTO and RPO parameters and also the definition of steps of disaster recovery procedure. The work also briefly defines the basic procedure for determination of the RTO and RPO parameters, subsequent steps needed to design recovery solutions and analyzes various aspects which need to be considered when defining the parameters of continuity. The second practical part is based on the previous theoretically defined procedure and its aim is to analyze the data acquired during the questionnaire investigation in chosen company to determine the parameters of continuity for the applications in use and then suggest appropriate ways of addressing their backup and recovery. The result of this thesis is therefore a description of the analysis and practical application of methods for setting the parameters for continuity of information systems and the subsequent establishment of necessary measures.

Mezi retribucí a lidovým soudnictvím 50. let. Kontinuity a diskontinuity v soudních síních / Between Retribution and Peoples Justice of the 1950s. Continuities and discontinuities in the Courts.

Němcová, Veronika January 2018 (has links)
The thesis will concentrate on the dynamics of changes in the judiciary after 1945 with the emphasis given to continuity and discontinuity between retributional and popular courts in the early 1950s. The focus of interest will be dedicated the judicial practice in the postwar context and discourse of cleansing. Attention will also be paid to the changing mechanisms of disciplinary acts regarding judges in postwar Czechoslovakia and to strategies they followed In their careers in order to comply with the changing conditions. Key words: retribution, cleansing, extraordinary popular courts, the judiciary, judges, changes of personnel, continuity and discontinuity, peoples courts

Aerodynamické měření / Aerodynamic measurement

HEJNA, Tomáš January 2014 (has links)
This MA thesis focuses on the aerodynamic measurement in the teaching of physics using the Leybold Didactic didactic set. The thesis consists of instructions for solving 4 basic problems using the Leybold set; every problem comprises theoretical instructions for students and an experimental verification of the problem. The thesis should contribute to wider use of experimental teaching of physics in schools; also, it is supposed to serve teachers and students as a source of interesting laboratory assignments verifying aerodynamic laws and quantities. After minor adjustments, the thesis can be used in all types of schools, from elementary physics at primary schools to advanced physics at technical universities.

Modifikace Navier-Stokesových rovnic za předpokladu kvazipotenciálního proudění / Modification of Navier_Stokes equations asuming the quasi-potential flow

Navrátil, Dušan January 2019 (has links)
The master's thesis deals with Navier-Stokes equations in curvilinear coordinates and their solution for quasi-potential flow. The emphasis is on detailed description of curvilinear space and its expression using Bézier curves, Bézier surfaces and Bézier bodies. Further, fundamental concepts of hydromechanics are defined, including potential and quasi-potential flow. Cauchy equations are derived as a result of the law of momentum conservation and continuity equation is derived as a result of principle of mass conservation. Navier-Stokes equations are then derived as a special case of Cauchy equations using Cauchy stress tensor of Newtonian compressible fluid. Further transformation into curvilinear coordinates is accomplished through differential operators in curvilinear coordinates and by using curvature vector of space curve. In the last section we use results from previous chapters to solve boundary value problem of quasi-potential flow, which was solved by finite difference method using Matlab environment.

Tlumení tlakových pulsací v pružných potrubích / Damping of Pressure Pulsations in Elastic Pipes

Panko, Martin January 2008 (has links)
This diploma thesis deals with numerical simulation of pressure pulsations in elastic pipes. Continuity relation of fluid in elastic pipes, when calculating some damping in pipe material, is derived into practice. Rheological model of such a pipe corresponds to Voigt (Kelvin) model. For analysing dynamic effects in time periods are used numerical methods that deal with flow of compressible fluid: FTCS, Lax-Friedrichs and Lax-Wendroff method. The numerical results are confronted with the experiment. During the experiment simulation the method considers speed of sound in liquid like a function of pressure. This diploma thesis lays partial principles for finding elastic constants for describing dynamic characteristics of elastic pipes by measuring the pressure pulsations.

Zlepšení výroby aeronautické součásti / Production improvement of an aeronautical part

Laforce, Francois January 2011 (has links)
Since aircrafts manufacturers intend to produce low consumption and efficient aircrafts, parts become more and more difficult to machine. Some processes like „air machining“ enables a one-step production for complex aluminium alloy shaped parts. Although the assembly offers a large access to cutting tool, the lack of stiffness for large parts, and especially for thin-walled aeronautics parts implies strong vibrations during machining. The aim of the study is to solve these difficulties in order to keep productivity and improve surface quality. Further innovative solutions are considered like modal analysis, in-phase machining, spindle speed variation, 3 flutes end mill and variable helix angle mill. All propositions are tested on DMG 65 machine tool with Siemens 840D controller. Although vibrations are intrinsic to flexible parts, surface quality has been improved with higher cutting continuity and variable helix angle cutting tool.
