Hošková, Pavlína ; Skorunka, David (advisor) ; Skála, Bohumil (referee) ; Šauer, Karel (referee)
Research points on the fact that information level of your patiens is on a very good level. There is the space for improvement, mainly in the area of communication, which is the basic presumption of good relationship between patients and medics. Report is divided into two parts. The theoretical part is focused on information flow in health service. Experiential part describes the classification of patient's informedness levels within the hospitalization. Research sample are 68 patients. Result shows, that consequent communication is needed. There was biggest dissatisfaction in this sphere. The target is to reach high quality in provided care with active client's attendance and his satisfaction. Main point is good information flow between patient and medic about health state.

Standard of general laic public knowledge of first aid giving
Nechanická, Veronika ; Slowik, Regina (advisor) ; Skála, Bohumil (referee) ; Býma, Svatopluk (referee)
The synopsis of principles of first aid, including the newest guidelines for cardiopulmocerebral resuscitation was elaborated in this work. The selected states altering the human health or life-threatening conditions were mentioned, including their recommended management. The recommendations for appropriate calling for an ambulance were elaborated and the remark concerning criminal law was made. In the practical part of this work the answers of 99 respondents to questions investigating the basic sociometric and demografic data and elementary knowledge of first aid were analyzed. The hypotheses that people who had undergone first aid training, who had dealt with the accident or emergency in real life, and people with medical education have better knowledge of first aid were confirmed. The people who evaluated their own knowledge of first aid as good from their subjective point of view really had better knowledge. The hypothesis of direct proportion between knowledge of first aid and achieved education was confirmed in the female group. The assumption that the youngest and the oldest generation has the worst knowledge of first aid was also confirmed. The surprising findings were revealed in the male group. A group of the youngest respondents and a group with the lowest education had the best...

Patients'/clients'needs after radical prostatectomy
Svitáková, Pavlína ; Skála, Bohumil (advisor) ; Novák, Ivo (referee) ; Langrová, Eva (referee)
Patients`/Clients` Needs after Radical Prostatectomy The theoretical part of the present thesis, which is focused on needs of patients/clients after the radical prostatectomy, is concerned with the needs of an ill human as such within the framework of the holistic concept. Then, it analyses specific prostatectomy-patient-related needs. The thesis reveals the fundamental of this operation and its lasting ill effects that cause various problems and bring along specific needs. The above-mentioned effects concern all parts of human personality. The thesis deals with the nurse's role while identifying and satisfying these needs within the framework of the nursing process. The importance of an appropriate education is stressed as well. The practical research part not only analyses the level of patients'/clients' foreknowledge of eventual post-operative problems and complications but it monitors also their concrete needs in different stages of the post-operative period.

Motor-Generator For Swirl Turbine
Huzlík, Rostislav ; Skala, Bohumil (referee) ; Duroň, Jiří (referee) ; Ondrůšek, Čestmír (advisor)
The aim of this doctoral thesis is to design a motor-generator for swirl turbine. Swirl turbine is a relatively new type of turbine developed at the Department of Fluid Engineering Viktor Kaplan Energy Institute FME BUT. Swirl turbine is designed for use on small head, where the classical types of turbines either poor efficacy or are economically disadvantaged. As suitable construction for the motor-generator was selected synchronous machine with permanent magnets and with axial magnetic flow with coreless stator. As part of the work is carried out calculating the properties of turbines for defined operating point simulation model of the turbine. After already made draft motor-generator to optimally meet the characteristics of the turbine. The complete design of the motor-generator is validated by calculating the finite element method models. Designed machine must be able to work as a generator and as a motor, if it was necessary to use a turbine as a pump.

Fault-Tolerant Control of a Flux-switching Permanent Magnet Synchronous Machine
Aboelhassan, Mustafa Osman Elrayah ; Singule, Vladislav (referee) ; Skala, Bohumil (referee) ; Skalický, Jiří (advisor)
Je jasné, že nejúspěšnější konstrukce zahrnuje postup vícefázového řízení, ve kterém každá fáze může být považována za samostatný modul. Provoz kterékoliv z jednotek musí mít minimální vliv na ostatní, a to tak, že v případě selhání jedné jednotky ostatní mohou být v provozu neovlivněny. Modulární řešení vyžaduje minimální elektrické, magnetické a tepelné ovlivnění mezi fázemi řízení (měniče). Synchronní stroje s pulzním tokem a permanentními magnety se jeví jako atraktivní typ stroje, jejíž přednostmi jsou vysoký kroutící moment, jednoduchá a robustní konstrukce rotoru a skutečnost, že permanentní magnety i cívky jsou umístěny společně na statoru. FS-PMSM jsou poměrně nové typy střídavého stroje stator-permanentní magnet, které představují významné přednosti na rozdíl od konvenčních rotorů - velký kroutící moment, vysoký točivý moment, v podstatě sinusové zpětné EMF křivky, zároveň kompaktní a robustní konstrukce díky umístění magnetů a vinutí kotvy na statoru. Srovnání výsledků mezi FS-PMSM a klasickými motory na povrchu upevněnými PM (SPM) se stejnými parametry ukazuje, že FS-PMSM vykazuje větší vzduchové mezery hustoty toku, vyšší točivý moment na ztráty v mědi, ale také vyšší pulzaci díky reluktančnímu momentu. Pro stroje buzené permanentními magnety se jedná o tradiční rozpor mezi požadavkem na vysoký kroutící moment pod základní rychlostí (oblast konstantního momentu) a provozem nad základní rychlostí (oblast konstantního výkonu), zejména pro aplikace v hybridních vozidlech. Je předložena nová topologie synchronního stroje s permanentními magnety a spínaným tokem odolného proti poruchám, která je schopná provozu během vinutí naprázdno a zkratovaného vinutí i poruchách měniče. Schéma je založeno na dvojitě vinutém motoru napájeném ze dvou oddělených vektorově řízených napěťových zdrojů. Vinutí jsou uspořádána takovým způsobem, aby tvořila dvě nezávislé a oddělené sady. Simulace a experimentální výzkum zpřesní výkon během obou scénářů jak za normálního provozu, tak za poruch včetně zkratových závad a ukáží robustnost pohonu za těchto podmínek. Tato práce byla publikována v deseti konferenčních příspěvcích, dvou časopisech a knižní kapitole, kde byly představeny jak topologie pohonu a aplikovaná řídící schémata, tak analýzy jeho schopnosti odolávat poruchám.

Traction Drives with Asynchronous Motors
Běloušek, Josef ; Skala, Bohumil (referee) ; Richter, Aleš (referee) ; Patočka, Miroslav (advisor)
The first part of this work is devoted to the design of a traction asynchronous motor. The second part focuses on the developed method of the equivalent circuit parameters identification of the asynchronous motor in the form of -network. It is explained here that the equivalent circuit in the shape of a -network, alternatively of an inverse 'I-network, is exactly equivalent and fully-fledged to a T-network, although one of two stray inductances is formally missing. Furthermore, the relationships for the conversions of the T-network parameters to the -network parameters and back, and of the T-network to the inverse 'I-network and back are found. The third part deals with the calculation of the torque and the current characteristics of the asynchronous motor. A sensitive analysis of the torque characteristic is carried out on the individual parameters of the equivalent circuit of the asynchronous motor in the form of a -network and a method of the measurement by means of a flywheel is used for the torque characteristic measurement of the asynchronous motor. The fourth part focuses on the verification of the identified -network parameters in the Matlab-model of the traction drive.
