PERFORMANCE OF TWO TIEBACK WALLS AND ROCK ANCHORS IN A SHALE STRATUM

Romana Giraldo, Jorge Octavio 01 January 2018 (has links)
Tieback walls are typically design based on predetermined pressure distribution; however, these pressures were proposed based on performance of excavations. For retaining walls used in slope remediation, the application of these pressures might not be adequate; the construction procedure; therefore, a different response of the wall is expected. This document, presents the performance of two tieback walls installed in a shale stratum. Monitored responses is correlated with construction activities; these activates implied excavation and backfilling in both of the tieback walls. In addition, this research shows a numerical procedure to evaluate the anchor capacity based on the t- z approach. Finally, this study introduces an empirical method to estimate lateral wall deformation profiles and internal bending moments along a retaining wall installed in a clay stratum.

ANALYSIS OF THE PILE LOAD TESTS AT THE US 68/KY 80 BRIDGE OVER KENTUCKY LAKE

Lawson, Edward 01 January 2019 (has links)
Large diameter piles are widely used as foundations to support buildings, bridges, and other structures. As a result, it is critical for the field to have an optimized approach for quality control and efficiency purposes to measure the suggested number of load tests and the required measured capacities driven piles. In this thesis, an analysis of a load test program designed for proposed bridge replacements at Kentucky Lake is performed. It includes a detailed site exploration study with in-situ and laboratory testing. The pile load test program included monitoring of a steel H-pile and steel open ended pipe pile during driving and static loading. The pile load test program included static and dynamic testing at both pile testing locations. Predictions of both pile capacities were estimated using commonly applied failure criterion, and a load transfer analysis was carried out on the dynamic and static test data for both piles. The dynamic tests were then compared to the measured data from the static test to examine the accuracy. This thesis concludes by constructing t-z and q-z curves and comparing the load transfer analyses of the static and dynamic tests.

Ubytovací možnosti soběslavských měšťanů na přelomu 16. a 17. století / The lodging facilities of Soběslav's townsmen at the turn of 16th and 17th century

PETKOV, Petr January 2019 (has links)
This diploma thesis deals with the lodging facilities of Soběslav's townsmen at the turn of 16 th and 17 th century. The register of mentioned facilities in chosen Soběslav's houses had been made at request of Peter Vok of Rosenberg in April 1610. Municipal, guest and townsmen´s houses offered accommodation for 121 people as well as the abilities to build the same number of tables for them and to stable 704 horses, 333 of them inner town and 371 of them in the suburbs. The object of the thesis is analysis of the register. The main aim of analysis is the reconstruction of spatial arrangement of the lodging capacity into the oldest appropriate map. The location of houses of individual lodging provider was found out from the records on domestic markets which were registered in municipal land registers from the beginning of 16 th century until the mid of 17 th century. The amount of the lodging facilities of the lodging providers according to their houses was expressed by cartogram used in five maps. This thesis focuses on the factors which had been influencing the lodging capacity in Soběslav at the turn of 16 th and 17 th century.

Inscenace a adaptace Tylova Strakonického dudáka (1918-2017) / The scenic realizations and adaptations of Strakonický Dudák by J. K. Tyl (1918-2017).

LAFATOVÁ, Alžběta January 2019 (has links)
The diploma thesis concerns 1918-2017 stagings and adaptations of Strakonický dudák. We continue in the bachelor´s thesis Character of a bagpiper in 19th century Czech literature, a comparison with Pitinský's 2013 staging of Strakonický dudák. The aim of the diploma thesis is to show the changes in the attitude towards Tyl´s drama Strakonický dudák (1847) during the 20th and the beginning of the 21st century. On the basis of the interpretation of Tyl´s text we analyse chosen adaptations and stagings and we compare the main topics with Tyl´s version. In the first part we are concerned with interpretation of film adaptations of Tyl´s drama from 1937 to 1955. We examine different approaches to the theme and the way it is affected by socio-political situation. In the second part we deal with theatre stagings of Strakonický dudák. First, we deal with the position of theatre since the 1950s and with the demands on the adaptation on Tyl´s play. By means of interpretation of 1980-2006 stagings of Strakonický dudák we follow the shift from the adaptation based on Zdeněk Nejedlý´s thoughts to distinctive and original adaptations which offer current topics

Progresivita zatížení domácností daní z příjmů fyzických osob / Progressive tax burden on households on income from individuals

PAVLOVIČOVÁ, Lenka January 2019 (has links)
The theme of the diploma thesis is "Progressive tax burden on households on income from individuals". The aim of this work is to examine the progressive burden on households of personal income tax, using model households. The purpose is also to determine which taxpayers and in which households have the greatest tax burden. The study is conducted using an average tax rate. The analysis is performed in years 2016, 2017 and 2018 on four taxpayers (which are different by the amount of gross wage), which are in five different types of households (according to their composition, taxpayers apply different types of discounts or tax advantages). The results of the thesis show that the higher the gross wage, the higher the average tax rate (the higher the tax burn on the taxpayer), which is also more balanced than the poorer taxpayers. There is a minimal difference between rates year-on-year. Personal income tax is progressive.

Použití neuronových sítí pro generování realistických obrazů oblohy / Using neural networks to generate realistic skies

Hojdar, Štěpán January 2019 (has links)
Environment maps are widely used in several computer graphics fields, such as realistic architectural rendering or computer games as sources of the light in the scene. Obtaining these maps is not easy, since they have to have both a high- dynamic range as well as a high resolution. As a result, they are expensive to make and the supply is limited. Deep neural networks are a widely unexplored research area and have been successfully used for generating complex and realistic images like human portraits. Neural networks perform well at predicting data from complex models, which are easily observable, such as photos of the real world. This thesis explores the idea of generating physically plausible environment maps by utilizing deep neural networks known as generative adversarial networks. Since a skydome dataset is not publicly available, we develop a scalable capture process with both low-end and high-end hardware. We implement a pipeline to process the captured data before feeding it to a network and extend an already existing network architecture to generate HDR environment maps. We then run a series of experiments to determine the quality of the results and uncover the directions of possible further research.

Successful Strategies for Using Knowledge Management in Small and Medium-Sized Enterprises

Nsubuga-Mugoa, Josephine Kayaga 01 January 2019 (has links)
Knowledge management (KM) is vital for an organization to succeed in a highly dynamic and competitive world. The purpose of this multiple case study was to explore strategies that managers of small and medium-sized enterprises (SMEs) use to effectively integrate KM into business practices. The study population comprised 5 managers from 2 SMEs operating in Uganda. The eligibility criteria for this study were that participants had to be from Ugandan SMEs with a knowledge-intensive environment, managers with some responsibility of KM in the organization, and experienced with at least 1 year of successful KM practices. The conceptual framework for this study was theory z. Data were collected through face-to-face, semistructured interviews and reviews of company documents. Member checking was completed to strengthen credibility and trustworthiness. After methodological triangulation of the data sources collected and completion of Yin's 5-step process of data analysis, 5 themes emerged: having supportive leadership, ensuring sustainability, embedding KM practices in the organization culture, socialization, and embracing modern technology. The findings of this study might promote social change by supporting SME managers' use of KM to expand opportunities for employees to learn new skills and knowledge leading to the expansion of employment opportunities.

Air-quality sensor with 10-years lifespan

Hasanaj, Rilind, Abuhemidan, Ahmed January 2019 (has links)
Sensors with very low power consumption are required so that they can last a long time without the need to replace the batteries very often. Low power sensors can save significant cost and time incurred in battery replacement, especially in establishments and organizations that span over several buildings, floors and rooms. In this thesis, we investigate the use of the low-power wireless protocol Z-wave for sensors solutions that can last for approximately 10 years. An algorithm was created and we concluded that 10 years on a 480 mAh battery is not possible and the expected years need to be lowered or we need to increase the battery capacity.
