The subject of the thesis is to design a suspension footbridge over a river basin. Three different studies were created for the assigned problem. The suspension footbridge was chosen for the thorough elaboration. The most important part of the thesis is the static solution of the supporting structure. The structure model for calculation of impacts of selected strains including the impact of the footbridge construction was created in computational software Ansys. Assessment and dimensioning was carried out using manual calculation according the principles of limit states and applicable standards.

Mit dem Mappenwerk „Turmbilder“ (Abb. 1) widmete sich der 1954 in Oberammergau geborene Künstler Johannes Bierling einem der im doppelten Sinne herausragenden Bauten der Gotik. In seiner 1996 geschaffenen, aus 21 Linolschnitten bestehenden druckgrafischen Serie beschäftigte er sich explizit mit dem Westturm des Freiburger Münsters „Unserer Lieben Frau“ (siehe Dagmar Zimdars/Wölbert 2014; zum Kirchenbau insgesamt auch Freiburger Münsterbauverein 2011). Um 1270 begonnen, war dieser als einer der wenigen großen gotischen Kirchtürme bereits im Mittelalter (um 1340) vollendet worden und verfügt über den frühesten in Maßwerk aufgebrochenen Turmhelm (Dehio/Zimdars 1997, S. 197). Seine Höhe beträgt im Ganzen circa 115 Meter, wovon über ein Drittel auf den Turmhelm entfällt.

Thermal energy storage (TES) in a concentrating solar power (CSP) plant allows for continuous operation even during times when solar radiation is not available, thus providing a reliable output to the grid. Energy can be stored either as sensible heat or latent heat, of which latent heat storage is advantageous due to its high volumetric energy density and the high Rankine cycle efficiency owing to the isothermal operation of latent thermal energy storage (LTES) system. Storing heat in the form of latent heat of fusion of a phase change material (PCM), in addition to sensible heat, significantly increases the energy density, thus potentially reducing the storage size and cost. However, a major technical barrier to the use of latent thermal energy of PCM is the high thermal resistance to energy transfer due to the intrinsically low thermal conductivity of PCMs, which is a particularly acute constraint during the energy discharge. Secondly, for integration of TES in CSP plants, it is imperative that the cyclic exergetic efficiency be high, among other requirements, to ensure that the energy extracted from the system is at the maximum possible temperature to achieve higher cycle conversion efficiency in the power block. The first objective is addressed through computational modeling and simulation to quantify the effectiveness of two different approaches to reduce the thermal resistance of PCM in a LTES, viz. (a) developing innovative, inexpensive and passive heat transfer devices that efficiently transfer large amount of energy between the PCM and heat transfer fluid (HTF) and (b) increase the heat transfer area of interaction between the HTF and PCM by incorporating the PCM mixture in small capsules using suitable encapsulation techniques.   The second portion of the research focuses on numerical modeling of large scale latent thermal storage systems integrated to a CSP plant with the aforementioned enhancement techniques and cascaded with more than one PCM to maximize the exergetic efficiency. Based on systematic parametric analysis on the various performance metrics of the two types of LTES, feasible operating regimes and design parameters are identified to meet the U.S. Department of Energy SunShot Initiative requirements including storage cost < $15/kWht and exergetic efficiency > 95%, for a minimum storage capacity of 14 h, in order to reduce subsidy-free levelized cost of electricity (LCE) of CSP plants from 21¢/kWh (2010 baseline) to 6¢/kWh, to be on par with the LCE associated with fossil fuel plants. / Ph.

Indiana University-Purdue University Indianapolis (IUPUI) / The following thesis looks into modeling a chilled water system equipped with variable speed drives on different piece of equipment and optimization of system setpoints to achieve energy savings. The research was done by collecting data from a case-study and developing a system of component models that could be linked to simulate the overall system operation.

In majority of schizophrenia patients, from the first episode of psychosis throughout the entire span of the illness, a cognitive deficit is one of the core symptoms. Assessing cognitive performance with empirically based methods is a vital part of clinical practice. Until recently, Czech adaptations of the MATRICS battery (standardly used for assessing cognition in schizophrenia worldwide) and the Tower of London, ToL (a basic test measure of executive planning ability) were absent. The primary aim of this dissertation thesis was to provide these methods for research and clinical use in Czech professional environment. This goal was achieved with both ToL and MATRICS in two basic steps. Firstly, Czech adaptations of both tests were carried out, namely translation of test instructions and establishment of standard administration and scoring. Secondly, complex psychometric analyses were conducted for both tests, including validation of their Czech versions for the purpose of assessing cognitive impairment in schizophrenia. The results suggest that ToL is a suitable tool for recognising executive planning deficit in general as well as in schizophrenia patients specifically. Also, the planning ability in schizophrenia patients, as measured by ToL, is one standard deviation below average when compared...

The study focuses on the Human Factors (HF) discipline and its role in improving aviation safety and efficiency within Air Traffic Control (ATC). The objective is to contribute to a better understanding of the ATC work domain and identify opportunities for improving performance, safety and efficiency. The research also aims to understand air traffic controllers' (ATCs) experience of the Mil i-ATC alarm system and propose enhancements to improve performance. Data collection was executed through observational research at a military air traffic control tower, and semi-structured interviews with ATCs, moreover, Work Domain Analysis and Thematic Analysis were employed for data analysis. The findings highlight key factors influencing ATC operational efficiency and safety, including communication, air traffic management, and alarm management, that is realized through social, technical and physical means. Moreover, workload, stress, situational awareness, teamwork, and decision-making were identified as interrelated elements within ATC. To enhance the Mil i-ATC alarm system, the study recommends considering alarm presentation, taking into account context and operational impact. Moreover, alarms without operational significance and false alarms are identified to cause frustration and undermine the reliability of the alarm system. Further research is necessary to determine the feasibility of presenting action plans directly in the system and how alarms should be listed. It is recommended that future studies focus on sustaining ATCs' motivation and alertness during monotonous tasks or low workload situations. Additionally, it is important to determine the appropriate level of automation in ATC management systems and evaluate controllers' trust in these systems.

Explosives have become increasingly common on the battlefield worldwide. Military personnel and civilians often experience blast loading to the lower extremity due to its direct contact with the ground and floor of vehicles. The pressure and axial loading from these incidents often lead to detrimental injuries. These injuries can be due to a number of mechanisms terming them primary, secondary, tertiary, or quaternary blast injuries. Of these injuries, this study will focus on primary and tertiary injuries, specifically bone fractures, compartment syndrome, and soft tissue disruption which often result from blast loading due to these mechanisms. However, the pressure and load levels causing these injuries are unknown. Currently, the methodologies, which study the injury criteria and design of blast mitigating structures, are limited. The main limitations are the lower rates of testing (automobile), specimen limitation (cadavers, surrogates, etc.), cost, and testing repeatability. Consequently, the goal of this dissertation is to develop a realistic computational model which can be used to improve the injury criteria, personal protective equipment (PPE), and vehicular structure in a cost effective and timely manner. Three Aims were thus pursued. For Specific Aim 1, a standing lower extremity was developed, verified, and simulated with several open-air blast loading conditions. Specific Aim 2 focused on validating the lower extremity model using experimental drop tower test results. In the drop tower simulation, the lower extremity model was successfully converted into a seated posture model and setup with similar loading and boundary conditions as the experiment. Specific Aim 3 involved incorporating a boot into the standing lower extremity model and evaluating its ability to mitigate pressure waves. In summary, Specific Aims 1 and 2 developed, verified, and validated a realistic human lower extremity model for the use in blast simulations. Specific Aim 3 further confirmed the models use in developing PPE.

Cooling towers form an important part of chilled water systems and perform the function of rejecting the heat to the atmosphere. These systems are often not operated optimally, and cooling towers being an integral part of the system present a significant area to study and determine possible energy saving measures. Operation of cooling towers in economizer mode in winter and variable frequency drives (VFDs) on cooling tower fans are measures that can provide considerable energy savings. The chilled water system analysis tool (CWSAT) software is developed as a primary screening tool for energy evaluation for chilled water systems and quantifies the energy usage of the various components and typical measures that can be applied to these systems to conserve energy, all while requiring minimum number of inputs to analyze component-wise energy consumption and incurred overall cost. A careful investigation of the current model in CWSAT indicates that the prediction capability of the model at lower wet bulb temperatures and at low fan power is not very accurate. A new model for accurate tower performance prediction is imperative, since economizer operation occurs at low temperatures and most cooling towers come equipped with VFDs. In this thesis, a new model to predict cooling tower performance is created to give a more accurate prediction of energy savings for a tower. Further the economic feasibility of having additional cooling tower capacity to allow for economizer cooling, in light of reduced tower capacity at lower temperatures is investigated.
