Electrical machine thermal protection
Němec, Martin ; Huzlík, Rostislav (referee) ; Mikulčík, Aleš (advisor)
This bachelor´s thesis deals with proposal for thermal protection of single-phase motor. The single part of thesis is devoted to collocation of motor temperature. Knowing this issue is important for thermistor right location. The parameters measuring and the model of simulated scheme are described in following parts. The simulated scheme is created in the Matlab programme, in a programme´s superstructure Simulink. At the close of this thesis, there are values measured and simulated compared.

Processing of Operating Load Data for Electrodynamic Test Bench
Prouza, Jiří ; Němec, Martin (referee) ; Novotný, Pavel (advisor)
This master's thesis deals with data processing for an electrodynamic test bench. The thesis presents a theoretical overview of signal distribution, determination of fatigue damage from random vibrations and a description of test benches. The next part deals with setting up the test time reduction in GlyphWorks software. The aim of this thesis is to process and create a procedure for an accelerated fatigue test from data measured during an operational test on a polygon. The data are then verified on an electrodynamic test rig using a Skoda Auto dynamic test room. The final part of the thesis contains data evaluation and a guide explaining how to easily create a test in the relevant software.

The Study of Logistic Conception of Distribution Stock
Kubala, Jakub ; Němec, Martin (referee) ; Jurová, Marie (advisor)
This master thesis “The Study of Logistic Conception of Distribution Stock” deals with global operation of distribution stock in its entire levels with target to design efficient communication methods with costumer and suppliers. Based on analyses of actual situation it effort to identify general poverties and find proper methods of it’s solution. First chapter is based on theoretical part. It explains basic logistical principals as one of the elements of each organization. Second chapter introduces Arcelor Distribuce CZ Company from work place way of look. Third chapter is dedicated to risk management as a theory of identification and evaluation actual or potential risks company may treat with. Fourth chapter the largest one defines particular issues company has to deal with and issues which block company’s way of growth. Further there are introduced steps heading to solve these problems. This thesis sets a target to identify and design solutions of main problems in communication in the first place, which block company’s natural evolution.

Physiotherapy for patients after stroke - problems of hemiparetic shoulder
NĚMEC, Martin
Stroke is one of the most common causes of premature disability and is the second leading cause of death in all developed countries. It is a suddenly developing involvement of a certain district of brain tissue, which was caused by a disorder of its blood supply. One of the complications after a stroke is the painful shoulder syndrome occurring on the hemiparetic upper limb. It is pain in the shoulder area with simultaneous movement limitation. The theoretical part of the bachelor thesis deals with epidemiology, distribution, causes, diagnostics, complications and basic risk factors of stroke. Furthermore, the theoretical part presents the kinesiology of the shoulder and explains the painful shoulder syndrome at hemiparetics with subsequent treatment options. The main aim of this bachelor thesis is to map and summarize the problems of the hemiparetic arm, create a suitable rehabilitation plan and subsequently evaluate the effects of the selected physiotherapeutic treatment. This is a qualitative research, where the research group consists of 3 patients after a stroke with a hemiparetic shoulder. The case report consists of an initial entrance examination. This is followed by 8 therapies focused on the hemiparetic shoulder and finally the final exit examination. From the results is to deduce that two patients experienced some improvement after receiving physiotherapy in the shoulder area. The last patient was not able to perform an exit examination for health reasons. The work can serve as educational material for physiotherapists, professional public or students of physiotherapy who want to increase awareness of the issue.
