Optical Birefringence Fiber Temperature Sensors in the Visible Spectrum of Light

This article describes experimental tests to determine PM fibers Panda style responses to a thermal source with different initial temperature. The aim of this study was to determine the sensitivity of a polarization maintaining fiber to the radiating heat, and to upgrade the space configuration and time response when using the 635 nm light. The sensitivity of the polarization maintaining fiber during excitation of both polarization modes is the principle of this sensor function. This excitation is caused by temperature change and by absorption of thermal radiation. This mechanism is used as an indicator for detection of temperature field disturbance. This article also provides links to previously published results and compares them to the results in this article

Suggestion lowenergy heating rezidental home.

Tato diplomová práce se zabývá problematikou vytápění nízkoenergetického domu. Cílem práce je seznámit se s různými variantami vytápění a následně vybrat tu nejvhodnější pro zvolený stavební objekt. V prvních dvou kapitolách jsou teoreticky zpracované varianty vytápění a nové moderní metody, které se v dnešní době používají. V následující kapitole je popsaný daný objekt, z níž se dozvídáme, z jakých materiálů je objekt zhotoven. V této diplomové práci je pomocí stavební výkresové dokumentace a výpočtového softwaru TechCON dům namodelován a následným výpočtem jsou zjištěny jeho tepelné ztráty. V programu je také namodelováno podlahové vytápění. Na základě vypočtených hodnot z programu jsou pro posuzování vhodnosti vytápění zvoleny tři varianty vytápění, a to tepelné čerpadlo vzduch/voda, tepelné čerpadlo země/voda a elektrický kotel. Pro každou z těchto variant jsou vypočteny investiční i provozní náklady, a následně za účasti dalších kriterií jsou vyhodnoceny pomocí metody WSA, abychom nalezli tu nejvhodnější variantu vytápění pro zvolený rodinný dům.This thesis deals with the problematics of a low-energy house heating. The aim of this work is to get familiar with different variants of heating and then choose the most suitable solution for the selected building. In the first two chapters there are theoretically described variants of heating and new modern methods that are used nowadays. In the following chapter we will learn what materials is the building made from. In this thesis the house is modeled using the building documentation and the calculation software TechCON and its heat loss is determined by subsequent calculation. The program is also used for modeling the floor heating. Based on the calculated values from the program, three heating variants are selected for the assessment of heating suitability, namely air/water heat pump, ground/water heat pump and electric boiler. For each of these options the investment and operating costs are calculated and subsequently, with the help of other parameters, they are evaluated using the WSA method to find the most suitable heating option for the selected family house.410 - Katedra elektroenergetikyvelmi dobř

Application of a 10 week coaching program designed to facilitate volitional personality change : overall effects on personality and the impact of targeting

The current study explored the outcomes of a 10 week coaching program designed to facilitate volitional personality change. It also explored the impact of targeting specific personality facets on change. This research builds upon the burgeoning literature challenging the view that personality is fixed. The results of the study indicated that the 10 week program resulted in significant increases in participant's conscientiousness and extraversion and significant decreases in neuroticism. These changes were maintained 3 months post-intervention for neuroticism and extraversion. Targeting of associated facets significantly interacted with time during the intervention period for emotionality and conscientiousness, but not for extraversion

Widening access in selection using situational judgement tests: evidence from the UKCAT

CONTEXT Widening access promotes student diversity and the appropriate representation of all demographic groups. This study aims to examine diversity-related benefits of the use of situational judgement tests (SJTs) in the UK Clinical Aptitude Test (UKCAT) in terms of three demographic variables: (i) socioeconomic status (SES); (ii) ethnicity, and (iii) gender. METHODS Outcomes in medical and dental school applicant cohorts for the years 2012 (n = 15 581) and 2013 (n = 15 454) were studied. Applicants' scores on cognitive tests and an SJT were linked to SES (parents' occupational status), ethnicity (White versus Black and other minority ethnic candidates), and gender. RESULTS Firstly, the effect size for SES was lower for the SJT (d = 0.13-0.20 in favour of the higher SES group) than it was for the cognitive tests (d = 0.38-0.35). Secondly, effect sizes for ethnicity of the SJT and cognitive tests were similar (d = similar to 0.50 in favour of White candidates). Thirdly, males outperformed females on cognitive tests, whereas the reverse was true for SJTs. When equal weight was given to the SJT and the cognitive tests in the admission decision and when the selection ratio was stringent, simulated scenarios showed that using an SJT in addition to cognitive tests might enable admissions boards to select more students from lower SES backgrounds and more female students. CONCLUSIONS The SJT has the potential to appropriately complement cognitive tests in the selection of doctors and dentists. It may also put candidates of lower SES backgrounds at less of a disadvantage and may potentially diversify the student intake. However, use of the SJT applied in this study did not diminish the role of ethnicity. Future research should examine these findings with other SJTs and other tests internationally and scrutinise the causes underlying the role of ethnicity

Recent trends, technical concepts and components of computer-assisted orthopedic surgery systems: A comprehensive review

Computer-assisted orthopedic surgery (CAOS) systems have become one of the most important and challenging types of system in clinical orthopedics, as they enable precise treatment of musculoskeletal diseases, employing modern clinical navigation systems and surgical tools. This paper brings a comprehensive review of recent trends and possibilities of CAOS systems. There are three types of the surgical planning systems, including: systems based on the volumetric images (computer tomography (CT), magnetic resonance imaging (MRI) or ultrasound images), further systems utilize either 2D or 3D fluoroscopic images, and the last one utilizes the kinetic information about the joints and morphological information about the target bones. This complex review is focused on three fundamental aspects of CAOS systems: their essential components, types of CAOS systems, and mechanical tools used in CAOS systems. In this review, we also outline the possibilities for using ultrasound computer-assisted orthopedic surgery (UCAOS) systems as an alternative to conventionally used CAOS systems.Web of Science1923art. no. 519

Verification of the mathematically computed impact of the relief gradient to vehicle speed

Terrain traficability is one of the key activities of military planning, firefighting and emergency interventions. Terrain traficability is affected by many factors and terrain slope is one of them. Deceleration ratio that represents the influence of slope inclination is dependent on a technical attributes of vehicle. The results of field terrain tests suggest that deceleration ratio established via calculation does not have to correspond with practical experience
