Within the master’s thesis there is comparison of different structures of ARC oscillators with respect to their harmonic distortion. Individual blocks of oscillator are analyzed. Attention is paid to choosing and design of suitable ARC filter structure and possibilities of its tuning. Also possibilities of stabilization of amplitude are analyzed. Different types of controlled amplifiers and circuits for controlling of their amplification are discussed. Next captures are focused to designing and simulation of the ARC oscillator. The oscillator can be tuned in the frequency range from 100 Hz to 20 kHz with harmonic distortion smaller than 1%. At the end of the thesis, practical realization of the proposed circuit is described. Also results of the measurement of parameters of the oscillator are given.

This thesis of a Master´s distant study program of M-STM Machinery technolofy and industrial design specialization proposes more efficient and quicker way of assembeling pipe technology systems using prefabrication of so called SPOOL "figure" in advance. The thesis proposes and from the technical-economical point of view assesses ways of manufacturing and proceeding the workshop weldings on pipe systems. While construction and design the programes of Areva and Autodesk companies were used.

Traffic congestion has been identified as the one of the most serious problems in urban transportation. Not much can be done in finding solutions to recurring congestion problem. As a part of ITS research in the 90's, a lot of research is being focused on non-recurring congestion which is caused primarily by incidents. Incident Response is a part of Incident Management programs but it has not been researched in depth. In this project, an incident response plan has been formulated on paper. A contact information database and a resource allocation database are the part of the plan. The resource allocation database has been created using expert knowledge and statistical anaJysis on the incident survey conducted in Fairfax County in northern Virginia. This plan is converted to a computer based response plan. It is then implemented using the ARCIINFO GIS software on a Unix Sun Sparc 2000 platform. The response plan is the part of a larger 'Wide Area Incident Management System Software'. / Master of Science

The influence of electromagnetic stirring in an electric arc furnace (EAF) has been studied. Using numerical modeling the effect of electromagnetic stirring on the thermal stratification and fluid flow has been investigated. The finite element method (FEM) software was used to compute the electromagnetic forces, and the fluid flow and heat and mass transfer equations were solved using a finite volume method (FVM) software. The results show that electromagnetic stirring has a significant effect on temperature homogenization and mixing efficiency in the bath. The important part of this study was calculation of heat transfer coefficient. The results show, electromagnetic stirring improves the heat transfer from the melt to scrap which is dependent on the stirring direction and force magnitudes.

We discuss results dealing with universal cycles (ucycles) and s-overlap cycles, and contribute to the body of those results by proving existence of universal cycles of naturally labeled posets (NL posets), s-overlap cycles of words of weight k, and juggling patterns. The result on posets is, to the best of our knowledge, the first demonstration of the existence of a ucycle whose length is unknown.

The main task of this thesis was to deal with the specifics of the location so that the newly proposed structure had the potential for sustainable development of all its features. In future space transport terminal station does not arise only an end in itself, but mainly there is created an interaction point, which results in a value and attractiveness of the surrounding land. Ultimately, this process has lead to a zcelení city, to enhance its attractiveness and the external and internal view of the city itself.

In an effort to make Appalachia a more acceptable and productive region to the rest of the country, the Appalachian Regional Commission (ARC) was created in 1965. This agency continued some of the efforts began by other redevelopment agencies, such as the Tennessee Valley Authority (TVA), the Office of Economic Opportunity (OEO), and the Area Redevelopment Agency (ARA). What was not in the original plan, however, was keeping an enormously rich existent culture alive. Having effected tremendous advancement in infrastructure, followed by continued industrial growth and health, social, and educational reform, Appalachia continues to experience the repercussions of those changes on the cultural level. Using personal interviews with volunteers who are older-generation, native Appalachians, regarding their experiences of life before, during, and after the ARC was introduced, this thesis explores the significance of cultural preservation, not only for rural Appalachians, but also for other groups threatened by cultural extinction.

Surveys of emergent terraces and U-series ages for ten sites along the coast of East Timor provide estimates of late Quaternary differential vertical strain in the most mature region of the Banda Arc-continent collision complex. Over a distance of ~180 km vertical displacement rates vary between 0.0 and 1.6 meters per 1000 years for the last 150,000 years. Two models of terrace formation (constructional and erosional) are applied to interpret terrace ages from coral ages and to estimate uplift rates. The highest uplift rates are from three sites over a distance of 15 km along the coast. Uplift rates were estimated from corals approximately 20 m above mean sea-level that yield ages of c. 54–74 ka, which correspond to the 3a (c. 49-52 ka) sea-level highstand and a possible highstand or standstill in regression between the 5a sea-level highstand and the 4 sea-level lowstand . These ten sites and resulting variable uplift rates are used constrain a wavelength of deformation due to the fact that recognizable terraces along the coast are not consistent. Terraces cannot be correlated over distances greater than 10 km, vary between 2 to 25 in number, and reach varying altitudes between ~100 and 600 meters above sea-level. The results propose that along an east-west transect a background surface uplift rate increases from 0.1 meter per 1000 years near Subau to 0.5–0.6 meters per 1000 years west of Baucau and remains at that rate for over 170 km. This would indicate a broad wavelength of deformation, possibly related to lithospheric scaled processes. However, superimposed on this background uplift rate is a shorter wavelength (< 15 km) of uplift with a mean of 1.2 meters per 1000 years and peak surface uplift at 1.6 meters per 1000 years. Another interpretation proposes the possibility of at least three shorter wavelength features. The shorter wavelength is likely associated to deformation in the upper crust. This study associates the crustal deformation to Quaternary movement along retro-wedge thrust faults at depth, which indicates active crustal shortening in Timor region.

Ceramics from three Utah great houses, Bluff, Cottonwood Falls, and Edge of the Cedars, were analyzed and compared with ceramics from Three Kiva Pueblo, which is not a great house site but was occupied contemporarily. Data on jar and bowl rim diameters were considered to understand great house feasting dynamics. Cooking jars with large rim diameters were more common at Three Kiva than they were at the great houses. This suggests that Three Kiva residents prepared large batches of food more frequently than great house residents. Distributions of Mancos Black-on-white bowl diameters were very similar at great houses and Three Kiva, but Three Kiva had bowls with larger diameters than those found at the great houses. Jar sizes suggest it is possible that feasting at great houses took place with a potluck model; however, bowl sizes suggest that Three Kiva also hosted feasts. Data on ceramic origins were considered to look for direction and strength of relationships with outside regions. All of the great houses had higher proportions of imported ceramics than Three Kiva, suggesting that great house residents interacted with people from other regions more frequently. All sites had large proportions of imported ceramics from the Kayenta region. All great house sites had Chuskan and Cibolan sherds, suggesting interaction with Chaco Canyon. Proportions of imported ceramics and the regions from which they came varied for each site, indicating that site residents maintained independent connections to people living in other regions.
