Městský úřad Leopoldov / Municipality Leopoldov

Prosnanová, Dominika January 2020 (has links)
The goal of my master‘s thesis is to project a municipality with an attached library in the town Leopoldov. The municipality building has two aboveground floors and the library is designed as a single-floor structure. Both are designed to be barrier-free. The construction system is made out of limestone-sand blocks. The ceilings are mostly made out of prestressed ceiling panels, except for the first floor of the municipality, where the prestressed panel ceiling is combined with monolithic ceiling plates made out of reinforced concrete. The roof of the library is projected as a green roof with a terrace and the municipality has a flat deck roof with river gravel.

Horský penzion s restaurací / Mountain guest house and restaurant

Dudáš, Peter January 2019 (has links)
The title of my diploma thesis is Mountain Pension with Restaurant and is written in English. My task was to create a mountain guesthouse that would serve as a background for other cottages in the neighborhood. I designed a wellness center as well as a restaurant and accomodation in the building. It is a two-storey with basement. The ground floor is reserved for the restaurant, the basement for wellness and the attic is designed for temporary accomodation. From a technical point of view, the construction system consists of a brick walls and monolithic ceilings. The main vertical supporting elements are ceramic walls and the main horizontal elements are one-way reinforced slabs which are reinforced using reinforced concrete core. The roof is made of wooden trusses.

On the Possibility of Probing Early Matter Domination with Primordial Black Holes / Primordiala svarta hål och tidig materiadominans

Stomberg, Isak January 2021 (has links)
Primordial black holes (PBHs) are expected to form in the very early universe, and therefore, we could use them to probe pre­BBN times. Astrophysical observations permit the placement of bounds on the abundance of PBHs. Combining these bounds with predictions of PBH formation and the resulting PBH abundances, we explore the possibility to constrain an epoch of early matter domination (MD). For this analysis, we incorporate the recently obtained and most stringent bounds on PBHs from 21 cm observations. We assume density perturbations described by a near­power­law form of the curvature power spectrum consistent with the Planck 2018 results and derive the corresponding PBH mass function using recent results from the literature. To place constraints on an early matter­dominated (MD) epoch, we compare this with up­to­ date bounds on PBHs, adding those from 21 cm astronomy, using a formalism to apply monochromatic constraints to extended mass functions. We find that 21 cm bounds on PBHs may probe early MD if it lasts for a duration of at least ∼ 12 e­folds and ends at a reheating temperature T_min < T_reh ≲ 105.5 GeV, where Tmin depends on the duration of the MD, the spectral index ns, and αs. For optimistic assumptions, our derived limits on the spectral index ns extend into the Planck 2018 67% upper confidence region of n_s = 0.9649 ± 0.0042, nearly reaching its median n_s = 0.9649, if we neglect the running αs. Our bounds on the running α_s show that early MD is incompatible with positive running α_s ≳ 0. / Primordiala svarta hål förutsäges ha skapats i det mycket tidiga universum. Ur detta förstår vi att dessa svarta hål ger oss en länk till universums tillstånd under deras skapelse och att vi genom studiet av primordiala svarta hål kan skymta detta tillstånd. Restriktioner på mängden primordiala svarta hål i universum kan beräknas utifrån astrofysiska observationer. Jämförelse av dessa restriktioner med teoretiska förutsägelser av vilka mängder av primordiala svarta hål som skapats vid olika tillstånd medger att vissa tillstånd utesluts. I detta arbete undersöker vi just detta samband och avser etablera huruvida de starkaste restriktionerna på primordiala svarta hål, speciellt från 21 cm observationer av universum, kan utesluta ett kosmologiskt scenario med tidig materiadominans. För att göra detta antar vi att störningar i den annars homogena energidensiteten kan beskrivas med hjälp av ett nästan­storleksoberoende potenssamband vars form ges av resultat från Planck kollaborationen 2018. Givet denna potenslag beräknar vi en form för de primordiala svarta hålens massdistribution medelst resultat från den vetenskapliga litteraturen. Vi jämför sedan dessa förutsägelser med de senaste mängdrestriktionerna på primordiala svarta hål, inkluderat dem från 21 cm observationer, för att erhålla nya begränsningar på tidig materiadominans. Vi tar i beaktande att massdistributionen av primordiala svarta hål inte är monokromatisk, utan utbredd. Resultatet av denna analys är att tidig materiadominans är inom räckhåll för att uteslutas medelst studier av primordiala svarta hål om perioden av materiadominans är längre än ∼ 12 e­folds och att den slutar vid återuppvärmningstemperaturen T_min < T_reh ≲ 10^5.5 GeV, där Tmin beror på hur länge den tidiga materiadominansen varar, på det spektrala indexet ns och det spektrala indexets derivata αs. För optimistiska antaganden äventyrar dessa restriktioner på materiadominans resultat från Planck kollaborationen 2018 i det att det övre konfidensintervallet på det spektrala indexet n_s = 0.9649 ± 0.0042 är exkluderat, och att förändringen av detta index, α_s, inte kan vara positiv då vi låter storleksordningen minska.

Implementation and Comparative Analysis of Head-Related and Binaural Room Impulse Response in a Mid-Side Decomposition / Implementation och Jämförande Analys av Huvud-Relaterade och Binaurala Rumsimpuls-Responser i en Mid-Sid Uppdelning

Ling, Jonathan January 2023 (has links)
This thesis aimed to clarify the essential factors involved in externalising audio over headphones. Extensive research was conducted, examining binaural cues and the latest advancements in the field. A novel approach was proposed, which applied HRIRs and BRIRs on a Mid-Side decomposition. The objective was to enhance frontal externalization while increasing control over centre-panned and side-panned elements. The proposed method underwent rigorous testing in various setups, accompanied by objective and subjective evaluations. The objective measures were then correlated with the findings from the subjective evaluations. Interaural coherence analysis revealed that the BRIR exhibited lower overall coherence values than the HRIR. This was anticipated, considering BRIRs capture room acoustics that impact sound perception compared to anechoic conditions. Introducing simple room acoustics, such as early reflections and reverberation tails, significantly reduces the coherence in higher frequencies for HRIR. Connecting these findings to the conducted listening test, it is observed that lower IC generally corresponded to a wider audio configuration. However, assessing frontal externalization proved challenging. Among the tested configurations, the two BRIR models achieved the most width, with the unsmoothed version performing slightly better. This suggests a tradeoff between externalization and colouration, as the smoothed BRIR model excelled in spectral colouration and preference. For the HRIR, adding room acoustics slightly increased the width. It received lower ratings regarding spectral colouration and was not preferred over the HRIR model without room acoustics. This reinforces the significance of preserving the original spectral characteristics. / Denna avhandling hade som mål att klargöra de väsentliga faktorer som är involverade i att externalisera ljud över hörlurar. Omfattande forskning genomfördes, där binaurala ledtrådar och de senaste framstegen inom området undersöktes. Ett nytt tillvägagångssätt föreslogs, där HRIRs och BRIRs applicerades på en Mid-Sid-uppdelning. Målet var att förbättra frontal externalisering i kombination med mer kontroll över centrerade och sido-justerade element. Den föreslagna metoden genomgick rigorösa tester i olika inställningar, åtföljda av objektiva och subjektiva utvärderingar. Objektiva mätningar korrelerades sedan med resultaten från de subjektiva utvärderingarna. Analysen av interaural koherens visade att BRIR hade lägre övergripande koherensvärden än HRIR. Detta var väntat eftersom BRIR fångar upp rumslig akustik som påverkar ljuduppfattningen jämfört med anekoiska förhållanden. Att införa enkla rumsliga akustikegenskaper, såsom tidiga reflektioner och efterklangssvansar, minskar signifikant koherensen i högre frekvenser för HRIR. Genom att koppla samman dessa resultat med de genomförda lyssningstesterna kan man observera att lägre interaural koherens generellt korresponderade med en bredare ljudkonfiguration. Dock visade det sig vara utmanande att bedöma frontal externalisering. Bland de testade konfigurationerna uppnådde de två BRIR-modellerna störst bredd, där en icke spektrum-justerad version presterade något bättre. Detta tyder på en avvägning mellan externalisering och färgning, eftersom den slätade BRIR-modellen presterade bra i både färgning av ljud och preferens. För HRIR ökade bredden något genom att lägga till rumslig akustik. Den fick lägre betyg avseende spektralfärgning och föredrogs inte framför HRIR-modellen utan rumslig akustik. Detta understryker vikten av att bevara de ursprungliga spektrala egenskaperna.

Návrh a realizace technologického demonstrátoru senzorické sítě pro diagnostické účely / Design and implementation of the sensor network technological sample for diagnostic purposes

Venglář, Vojtěch January 2018 (has links)
The purpose of this thesis was to design and implement a prototype of binary topology sensor network (as proposed in patent CZ 306855 B6). Important part was evaluation of this type of network. A survey of commonly used sensors and technologies used in intelligent buildings and sensor networks was created. The gathered information was used for the evaluation. A network for analog signal transmission was designed and implemented (including all the elements) based on the patent proposal. A number of configurations was proposed to test the network features. Measurements were performed using all the proposed configurations. Two devices were used for the measurement: STM32 Nucleo F303K8, MyRIO (by National Instruments). Looking at the measured data, we can tell that the consistency is good enough to declare this network functional as a concept. However, we cannot recommend this type of network for high precision applications at the time, due to some accuracy and consistency issues. We have also detected relatively significant noise in the data. That could be caused by many external influences, partly by faulty design of the components.
