This thesis provides an assessment of the effectiveness of micro unmanned aerial vehicles (MUAVs) as a tool for collecting condition data for transportation infrastructure based on multiple field experiments. The primary experiment entails performing a level of service (LOS) condition assessment on multiple roadside sample units at various locations across the state of Texas. A secondary field experiment entails performing a pavement condition index (PCI) survey on airfield pavements. The condition of these sample units were assessed twice: onsite (i.e., ground truth) and by observing digital images (still and video) collected via a MUAV. The results of these surveys are then analyzed to determine if there are statistically significant differences in the standard deviation and mean values of the condition ratings. This study shows that in favorable site conditions, the MUAV demonstrates promise for improving current roadway inspection methods. However, limitations of the MUAVs field performance show that there is need for improvement in this technology before it can be implemented.

The use of rayon in 1920s and 1930s garments confronts conservators with new challenges: definitive fibre identification involves more than basic microscopy and treatment can be difficult with little available research on early rayon and its conservation. Rayon is expected to degrade similarly to other cellulosic fibres; however, since it is a regenerated fibre, rayon is at risk of doing so at a faster rate. The purpose of this research was to develop and test a protocol for the identification of viscose and cuprammonium rayon and to determine whether early rayon dresses have condition issues at this time. Polarizing microscopy, hot-stage microscopy, acetone solubility and relative fibre refractive index were explored as fibre identification techniques, resulting in the development of a rayon identification scheme. 1920s and 1930s rayon dresses were surveyed for condition and it was determined that dresses in this sample have limited condition issues at this time.

Läckö Castle is an historic building that has never been permanently heated but has been dehumidifiedsince the early 2000s to house museum collections. The purpose of the work was to evaluate thedehumidification performance and compare the climate with the state of preservation of wooden wallpaintings. Compiled climate recordings for different rooms in the castle from 1997 to 2009, before andduring dehumidification, were used and compared to the outside climate. The RH set point value of 70 % for dehumidification was not reached often, especially in winter with high outside RH. Wood painted witha linseed oil paint performed well, whereas paint containing resin was seriously damaged. It is concludedthat microclimatic differences in relation to dominating wind direction are important. The air exchangeof the building is very decisive for dehumidification efficiency.

With the growing need to maintain roadway systems for provision of safety and comfort for travelers, network level decision-making becomes more vital than ever. In order to keep pace with this fast evolving trend, highway authorities must maintain extremely effective databases to keep track of their highway maintenance needs. Florida Department of Transportation (FDOT), as a leader in transportation innovations in the U.S., maintains Pavement Condition Survey (PCS) database of cracking, rutting, and ride information that are updated annually. Crack rating is an important parameter used by FDOT for making maintenance decisions and budget appropriation. By establishing a crack rating threshold below which traveler comfort is not assured, authorities can screen the pavement sections which are in need of Maintenance and Rehabilitation (M&R). Hence, accurate and reliable prediction of crack thresholds is essential to optimize the rehabilitation budget and manpower. Transition Probability Matrices (TPM) can be utilized to accurately predict the deterioration of crack ratings leading to the threshold. Such TPMs are usually developed by historical data or expert or experienced maintenance engineers' opinion. When historical data are used to develop TPMs, deterioration trends have been used vii indiscriminately, i.e. with no discrimination made between pavements that degrade at different rates. However, a more discriminatory method is used in this thesis to develop TPMs based on classifying pavements first into two groups. They are pavements with relatively high traffic and, pavements with a history of excessive degradation due to delayed rehabilitation. The new approach uses a multiple non-linear regression process to separately optimize TPMs for the two groups selected by prior screening of the database. The developed TPMs are shown to have minimal prediction errors with respect to crack ratings in the database that were not used in the TPM formation. It is concluded that the above two groups are statistically different from each other with respect to the rate of cracking. The observed significant differences in the deterioration trends would provide a valuable tool for the authorities in making critical network-level decisions. The same methodology can be applied in other transportation agencies based on the corresponding databases.

The main goal of this diploma thesis is diagnostics and vocational training in assessment of existing structure of the center of leisure time for children. The teoretical part is focused on vocational training in assessment of existing structures by ČSN ISO 13 822 - Bases for design of structures - Assessment of existing structures and assesment of brick structures. The designing strength of masonry and mortar is defined in the end of theoretical part. The practical part continues with real construction, where diagnostic methods based on technical survey are applied and in the end describes present state of real construction with plan for required steps to secure safety. As a result of this thesis is also a demonstration static report.

The diploma thesis deals with the passport of family houses and its creation. The first part describes the building condition survey from a theoretical point of view, its advantages, purposes and sorting, possible owners and so its legislative background. Thereafter it describes in detail the procedure of making the passport and applies the procedure on a particular family house in Brno. Medium passport of the family house focuses on describing the structural and technical condition. It also describes the current faults, errors and methods whose reveals them. Subsequently, the proposals for solution of these adjustments follows together with the resolution of emergency in specific cases.
