Possibilities of evaluation durability of the surface layer of concrete structures
Blažek, Michal ; Žalud, Oldřich (referee) ; Vymazal, Tomáš (advisor)
The thesis is focused on possibilities of durability evaluation of surface layer of concrete structures. The durability of concrete surface layer usually determines the durability of the structure as a unit. It has to be determined in what environment the structure is situated and what influences it has to face, to set the durability of the structure. There is a several normative prescription to set the resistance of the structure. There is formulated a summary of the most widely used and known prescriptions in the theoretical part of the thesis. It is a lot of effort to estimate the durability of the concrete by estimation of permeability of the concrete surface layer recently. Thus these methods are also formulated in the summary and there are compared the individual outputs of the tests. The permeability and pore structures of the concrete surface layer are crucial parameters for the durability of concrete structure. These parameters influence the construction properties of the concrete as well, thus the thesis is focused on relationship of the pore structure and the strength in press of the concrete.

Influence of Initial Conditions on the Modulus of Elasticity of Concrete for Bridges
Blažek, Michal ; Bílek,, Vlastimil (referee) ; Cikrle, Petr (advisor)
Beside the compressive strength of concrete, which is considered as the basic parameter parameter for design of concrete structures a modulus of the concrete elasticity should be set as well. This thesis deals with influences, which are acting on the concrete, particularly within the initial stage of its hardening (i.e. within 28 days after casting). Nowadays, when time is the most valuable factor, some knowledge is required about mechanical properties of concrete earlier than after above mentioned 28 days and to apply them advantageously. The concrete in initial stage of hardening is influenced by many factors that affect progress of the elasticity modulus during the course of the time. For understanding of these problems a literature search was performed, as well as the experiment demonstrating the effect of temperature on the modulus of the concrete elasticity. The effect of temperature on the modulus of elasticity of concrete in initial stage of hardening has not been intensively studied yet. Therefore, more attention is paid to it by this elaborate. The experiment investigated the static and dynamic elastic modulus of concrete, whose recipe is similar to one used for production of prefabricated and prestressed bridge girders.

Evaluation of functional biomechanical parameters of locomotion depending on the performed amputation in LL
Blažek, Michal ; Jelen, Karel (advisor) ; Šorfová, Monika (referee)
Title: Evaluation of functional biomechanical locomotion parameters depending on the performed amputation in LL Objectives: The goals of this thesis are the following: to compare asymmetry in step cycle time, pelvis, hip and knee movement and lower limb loading while walking, also to compare sagittal movement of pelvis while walking, postural stability in stance and subjective scoring of the functional skills and the quality of life in healthy controls, transfemoral and knee disarticulation amputees. Methods: 6 healthy controls and 3 amputees in each amputation group were included in this experiment. Qualisys motion capture system and Kistler force plates to collect objective data and specific sections of Prosthesis Evaluation Questionnaire for subjective scoring were used. The participants were observed while level walking forward and backward with self-selected speed and in a quiet stance with eyes either open or closed with narrow support base. Statistical analysis was carried out in Microsoft Excel. Results: In terms of asymmetry assessment of the selected ambulation parameters there were identified more symmetrical values in the knee disarticulation group in 63 % of 33 monitored parameters. However, statistical significance was exceeded only in a single parameter. Concerning pelvic movement in...

Case study of the physiotherapeutic treatment of a patient with total knee replacement
Blažek, Michal ; Martínek, Milan (advisor) ; Sohrová, Jana (referee)
This thesis deals with problematics of total knee arthroplasty (TKA) in a complex range. It is divided into two parts - the general one and the special one. The general part of the thesis targets on theoretical knowledge of the anatomy and kinesiology of the knee joint, knee arthritis and TKA as the most performed method of therapeutic intervetion in advanced stages of knee arthritis. Secondly, the special part contains the case study of the physiotherapeutic treatment in patient after TKA. Non-invasive methods and approaches in a range of the knowledge of the bachelor's studies on the Faculty of Physical Education and Sport, Charles University, were used during the pshysiotherapeutic treatment. Improvement of the patient's clinical status in almost all sections was the result of the physiotherapeutic intervention.

Social networks as a means of a law firm´s communication
Blažek, Michal ; Topolová, Ivana (advisor) ; Kubálková, Markéta (referee)
The bachelor thesis "Social networks as a means of law firm's communication" focuses on marketing and communication aspects of social networks, which are demonstrated on the example of Law firm Švehlík & Mikuláš's Facebook profile. The aim is to evaluate, how the social network profile affects the firm itself. The first, theoretical part, briefly characterises Marketing, Marketing mix, Marketing communication, On-line communication and last but not least Social networks. The main focus there is on Facebook. The second, practical part, describes the process of creating and controlling the Law firm Švehlík & Mikuláš's Facebook profile. In the end there is an evaluation of profile metrics, which leads to recommendations in order to improve the control and usage of Facebook profiles in general.

Financial reporting of software companies under IFRS
Blažek, Michal ; Vašek, Libor (advisor) ; Vácha, Petr (referee)
The thesis focuses on financial reporting under IFRS in comparison with US GAAP. It defines a software company and characterizes the business segment as very dynamic, rich in business combinations. The thesis describes methods of financial reporting of intangible assets, research and development and external sources for obtaining software. In-house created software is rarely capitalized that cause undervaluation of assets. In particular assets from business combination are reported. The thesis describes software revenue recognition according to current IFRS/US GAAP and the new revenue standard. It compares chosen aspects of reporting in segments: B2C, B2B, social networks, information security and search engines. In the conclusion, the thesis evaluates current situation in described segments regarding relevance of the standard to monetization models and intangible assets of software companies and it provides possible outlines in the future.
