Dizertační práce se zabývá zpracováním signálu fyzických řídicích kanálů systému LTE a vyšetřováním bitové chybovosti při přenosu řídicí informace z vysílače do přijímače v závislosti na podmínkách příjmu. Práce je rozdělena do dvou hlavních částí. První část práce je zaměřena na simulaci přenosu řídicí informace LTE v základním pásmu. Jsou zde prezentovány vytvořené simulátory řídicích kanálů ve směru uplink i downlink. Simulace jsou provedeny pro všechny druhy nastavení systému a základní modely přenosového prostředí. Jsou zde popsány výsledky vlivu použití MIMO technologií na kvalitu příjmu řídicí informace především v únikových kanálech. Druhá část práce je zaměřena na možnost nasazení systému LTE ve sdíleném pásmu ISM (2.4 GHz). Jsou zde představeny základní koncepce použití, na jejichž základě je vytvořen scénář simulací. Kapitola dále popisuje tvorbu simulátoru koexistence LTE a systému Wi-Fi v přeneseném pásmu ISM 2.4GHz. Jsou zde uvedeny výsledky simulací koexistence LTE a rušivého systému Wi-Fi provedených dle vytvořeného scénáře. Výsledky simulací koexistence LTE a Wi-Fi jsou ověřeny měřením v laboratorních podmínkách. Toto porovnání je důležité z hlediska optimalizace simulátoru koexistence. Dle výsledků obou typů simulací a měření jsou stanovena provozní doporučení, která mají přispět k bezpečnému a spolehlivému vysílání a příjmu řídicích informací LTE i při nepříznivých podmínkách příjmu.

Vliv pohybové intervence na fyzickou zdatnost a kvalitu života u pacientů po bariatrické operaci / The Effect of Exercise Intervention on Physical Fitness and Quality of Life in Patients after Bariatric SurgeryPacholíková, Pavlína January 2020 (has links)
Title: The Effect of Exercise Intervention on Physical Fitness and Quality of Life in Patients after Bariatric Surgery Objectives: The aim of this thesis is to evaluate the effect of a three-month physical intervention on the physical fitness and quality of life in patients after bariatric surgery. Compare the measured values from six-minute walk test (6MWT) and the questionnaire survey of quality of life between the group undergoing exercise program and the group of non-exercise patients. Methods: The diploma thesis was constructed as a quasi-experiment. A six-minute walk test, a visual analogue pain scale, a Borg scale and a standardized IWQOL-Lite questionnaire were used to asses physical fitness and quality of life. The study involved 28 patients (8 undergoing an exercise program, 20 non-excercisers). The groups were measured before the planned bariatric surgery and about 3-4 months after the surgery. For the analysis of final values, the Microsoft Excel and its add-in Realstatistics was used. Results: In patients undergoing the exercise program, the VAS on average decreased of 2,04 cm, 6MWT improved on average of 42,75 m, and quality of life of 34 points. In non-exercise patients there was an average decrease in VAS of 0,08 cm, an increase in 6MWT of 41,45 m and an increase in quality of life...

Porovnání statické fyzické atraktivity a atraktivity neverbálního chování u žen / Comparison of static physical attractiveness and attractiveness of nonverbal behavior in womenHladký, Tomáš January 2018 (has links)
The method of physiological measurement of sexual arousal to erotic stimuli is often used in sexological research. However, there is no concept of form of these stimuli to induce maximum possible sexual response from a person. It seems that female static physical attractiveness is an important factor in perception of the female, but it could be also female nonverbal behavior, dynamic attractiveness, which could influence perception and which could either enhance of reduce the overall attractiveness of a female. In the whole concept of attractiveness, there could be two components: "physical attractiveness" and "sexual desirability". In this diploma thesis, we address this problem and we compared static and dynamic stimuli with focus on specific behavior. The study had two parts. We used photographs of clothed and naked women and videos of castings of potential actresses in erotic movies; materials are available online for free. In the study I we used 90 photographs of faces and clothed bodies and found that there is a difference between physical attractiveness and sexual desirability. Moreover, face was a predictor of physical attractiveness and body was a predictor of sexual desirability. In study II we used sexually explicit videos and found that nonverbal behavior has just a minor influence on...

Znalosti pacientů s diabetem mellitem 2. typu o výživě a pohybové aktivitě / Knowledge of patients with type 2 diabetes mellitus about nutrition and physical activityValentová, Lucie January 2020 (has links)
This diploma thesis is focused on the knowledge of patients suffering from type 2 diabetes mellitus. The main aim of this work is to determine how well these patients are educated about type 2 diabetes mellitus depending on both the duration of the disease and whether they attend a nutritional therapist. The work is divided into a theoretical and a practical part. The theoretical part provides general information about diabetes mellitus. There is a marginal description of pancreatic function and the history, definition and classification of diabetes mellitus. Type 2 diabetes mellitus, its pathogenesis, clinical picture, diagnosis, screening, therapy and associated complications, both acute and chronic, are discussed in more detail. As part of type 2 diabetes therapy there is the most discussed non-pharmacological treatment, which includes dietary measures and physical activity. The practical part was formulated on the basis of quantitative research, which was carried out using a questionnaire survey. Data were collected from November 2019 to March 2020. 150 questionnaires were distributed to different inpatient departments and clinics in Jičín Hospital. 106 completed questionnaires were returned, but 24 of them had to be rejected due to incomplete or incorrect completion.

Faktory ovlivňující hodnocení atraktivity mužské postavy / Factors affecting perception of human male bodyTřebický, Vít January 2012 (has links)
According to previous research physical attractiveness plays an important role in our everyday life. People are treated differently on the basis of their physical appearance and from an evolutionary point of view physical attractiveness is a key factor in mate selection, being a cue of an individual's mate value and genetic qualities. Research shows that the highest attractiveness ratings tend to be given to physiques with a higher level of development of lean muscle mass and a V shaped upper body. Such a physique body constitution could indicates how a high level of physical fitness and a man's health of man and be a cue of the man's qualities as a mating partner. However, results of the previous studies are inconclusive due to the methods and stimuli employed. To address the shortcomings exhibited by the previous studies investigations, we ran two online studies. In the first study, women rated the attractiveness of a new and more extensive set of black and gray silhouettes derived from photos of the somatotypes. In the second study, we tested whether physical attractiveness of men can be increased by a voluntary change of their upper body shape. In both studies we were testing how interindividual differences of the female raters modulate the ratings of attractiveness. Results of the first study...

Nové přístupy k ochraně srdce před postischemickým selháním / Novel Approaches To Protect The Heart Against Postischemic FailureHrdlička, Jaroslav January 2021 (has links)
Ischemic heart disease and resulting heart failure (HF) belong to the leading causes of death in developed countries. In order to prevent HF and improve clinical outcome in patients with myocardial infarction, novel therapies are required to protect the heart against the detrimental effect of ischemic injury. Due to the failure to translate numerous available experimental cardioprotective strategies into clinical practice, the need for novel protective treatments persists. We have, therefore, tried to apply a novel approach to cardiac protection against the postischemic HF induced in rats by ligation of the coronary artery. For this purpose, we have studied (i) the preventive and therapeutic effects of adaptation to continuous normobaric hypoxia (CNH; 12% O2) and exercise training (ExT; treadmill running), and (ii) the possible cardioprotective potential of epoxyeicosatrienoic acid (EET)-based therapy in order to attenuate the postischemic HF in rats. Adaptation to CNH and ExT is known for their cardioprotection in acute ischemia/reperfusion (I/R) injury manifested as reduction of infarct size. EETs exert antihypertensive effects and thus seem to be perspective for the research in clinically relevant models of cardioprotection in hypertensive animals. Our results have revealed that: - CNH prior to...
