Gas heat pumps based on stroke engine
Bedřich, Miroslav ; Fiedler, Jan (referee) ; Pospíšil, Jiří (advisor)
The aim of this Diploma thesis is a description of gas heat pump (GHP) technology and the possibility of their usage in real life. Also units from the major manufactures of GHP units in the Czech Republic and abroad are evaluated from technical and economical point of view. The thesis as well includes a part where is decided if it is better to further develop GHP units with higher or lower performance. In the last part of thesis are cooling circuits designed for both lower and higher performance, than performance of existing GHP unit Polo 100. As a result, the units with higher performance are more perspective. Therefore heat plate exchangers, which serve as a condenser and an evaporator, are designed for unit with higher performance.

Project of Autonomous Heating Source
Pejcl, Jiří ; Ptáček, Michal (referee) ; Radil, Lukáš (advisor)
The diploma thesis deals with design of a suitable heat source for heating and hot water. There are dealt with operational costs of different types of heat sources, which are compared with one another. The next part is the implementation of specific proposal of the heat source - heat pump ground/water with deep wells and measuring system. The last part describes measuring several operating modes of the heat pump.

Heating the house by heat pump
Pinkas, Jan ; Kudela, Libor (referee) ; Pospíšil, Jiří (advisor)
The point of this bachelor thesis is a family house heating with a use of a heat pump. In the first part of the thesis the principle and working of a heat pump are explained. Also the basic sources of energy for the heat pump including their pros and negatives are talked over. Secondly in the practical part thermal losses and energy consumption of the chosen house are calculated. Based on those calculations the heat pump and the heating system are chosen. In the end the investment is evaluated.

Affect of standing frames on measuring postural stability
Klimešová, Lenka ; Koťová, Markéta (referee) ; Horáková, Pavla (advisor)
This semestral thesis is focused on postural stability. The aim is to introduce standing frame Balance Trainer and haptic floor Wii Balance Board. The theoretical part describes the postural functions, posturography and subsequently standing frame Balance Trainer and stabilometric platform Wii Balance Board. It is also designed the measurement protocol for affect of standing frames on measuring postural stability on a group of subjects and the measurement is realized. From the collected data are calculated parameters which are statistically processed and the affect of standing frames on measuring postural stability is evaluated.

Posturální stabilita stoje členů IZS využívajících balistické vesty
Čubanová, Slavka ; Kotolová, Veronika ; Hýbl, Jan ; Volf, Petr ; Hejda, Jan ; Sokol, Marek ; Leová, Lydie ; Kutílek, Patrik
Posturografie je obecný název pro techniky používané k hodnocení posturální stability těla. Vědecko výzkumný tým biomechanika a asistivních technologii KZOOO FBMI ČVUT se dlouhodobě zabývá optimalizací ochranných pomůcek pro IZS. Nejdůležitější funkcí těchto pomůcek je ochrana nositele před zraněním. Pro použití v praxi je však důležité i zajistit určitý komfort při nošení. Tyto pomůcky ve formě například balistické vesty, helmy, ochranných obleků pro hasiče atd. často stěžují samotný pohyb, jsou však pro vykonání některých úkolů nezbytné a nejde se bez nich obejít. V rámci ergonomické optimalizace těchto ochranných pomůcek jsme se zaměřili na měření posturální stability uživatelů ochranných vest. Zajímá nás, jestli a jak ovlivňuje nošení ochranných pomůcek posturální stabilitu členů IZS a jakým způsobem můžeme zvýšit komfort při nošení právě těchto nezbytných ochranných pomůcek.

The effect of hearing on standing stability
Pavlová, Monika ; Kučerová, Klára (advisor) ; Koutná, Sára (referee)
Standing stability is ensured by informations from the sensory systems, which include the vestibular system, vision, proprioception and hearing. The role of hearing is often neglected. This work aims to determine whether hearing plays a role in maintaining standing stability. The theoretical part of this bachelor thesis summarizes the existing knowledge about the auditory system. It deals with other systems that affect standing stability and, last but not least, tries to summarize the results of research into the effect of hearing on standing stability. The experimental part consists of the evaluation of stabilometric testing of 16 healthy probands (8 women and 8 men) using sound stimulation. Probands were tested in two measurements with an interval of at least 1 week. First in 10 conditions without sound stimulation. Then using sound stimulation, always in the same position - standing with closed eyes on a soft surface. The sound stimulation consisted of the following recordings: a spoken word that the proband understands (weather forecast in Czech language), elimination of auditory inputs with earplugs, stimulation with white noise, a spoken word that the proband does not understand (Chinese or Finnish) and a message with content the the proband was asked about after the measurement was finished...

Effect of sensomotoric insoles on postural stability in children with cerebral palsy
Bartošová, Simona ; Hráský, Pavel (advisor) ; Gryc, Tomáš (referee)
Author: Bc. Simona Bartošová Title: Effect of sensomotoric insoles on postural stability in children with cerebral palsy Objectives: Objectively assess the effect of sensomotoric insoles on children with cerebral palsy (CP) via COP (Centre of Pressure) parameters recorded on Kistler force plate. Methods: This thesis is designed as an experimental study. Selected paramaters of static postural balance were recorded via force plate to assess the effect of sensomotoric insoles. Five subjects (average age 7.2 years) with diagnosis of cerebral palsy were enrolled into the study. Data collection was carried out in two separated sessions - first before therapy and second after using the insoles for one month. The validity of the data was supported by three repetitions for each modification - upright plain stand with open eyes, upright stand with feet together and upright plain stand with closed eyes. Monitored parameters were: total trajectory of COP, amplitude of mediolateral displacement of COP, amplitude of anteroposterior displacement of COP and mean velocity of movement of COP. The data were analyzed in MATLAB® version R2019b. The statistical analysis was performed including the outliers elimination. The normality of data was checked by Lilliefors' test. In the case of normality a two-sample Student's...
