Abstract:

Aquesta tesi tracta sobre la influència que l’art català va exercir sobre Picasso durant els anys que aquest artista va residir a Catalunya. Aquesta influència no es planteja en abstracte sinó que es vehicula a través d’un parell d’artistes concrets, Santiago Rusiñol i Isidre Nonell. La tria és deguda a que van ser els artistes més representatius de les dues generacions amb les que es relacionà Picasso. Santiago Rusiñol pertanyia a la vella generació modernista, de la que era el principal referent. Isidre Nonell, sense ser un líder en sentit estricte, va ser l’artista més emblemàtic de la segü

Abstract:

The physical characteristics of aggregates (form, angularity, and texture) are known to affect the performance of hot mix asphalt (HMA) pavements. Efforts to develop relationships between these aggregate characteristics and aggregate performance in HMA pavements have been limited in the past due to inherent inaccuracies in the methods used to measure these characteristics. The recently developed Aggregate Imaging System (AIMS) offers an opportunity to accurately measure aggregate shape characteristics allowing them to be properly related to asphalt performance.

Chestnut is a relatively new nut crop to New Zealand and they do grow well in New Zealand conditions. Research to date in New Zealand indicated that New Zealand chestnuts present some unique features compared to chestnuts world wide. The two main unique problems with New Zealand chestnuts are the susceptibility to fungal disease Phomopsis (accounting for 40% loss of nuts at the wholesale markets) and the difficulty in the removal of the inner skin called the pellicle. No systematic drying trials had been performed on New Zealand chestnuts and therefore this research investigated the drying cha

The challenge of carrier recovery for digitally phase modulated, suppressed-carrier signals has been the target of much attention in mobile radio system design for many years. Code division multiple access (CDMA) cellular systems are now being deployed in mobile environments, and the performance of carrier recovery for CDMA is much less well understood. CDMA systems typically utilize lower bit energies, relying instead upon coding gain for reliable performance. As an additional challenge, the multiple access interference (MAI) inherent to direct-sequence spread-spectrum (DSSS) signalling furth

The problem of choosing efficient algorithms and good admissible orders for computing Gröbner bases in noncommutative algebras is considered. Gröbner bases are an important tool that make many problems in polynomial algebra computationally tractable. However, the computation of Gröbner bases is expensive, and in noncommutative algebras is not guaranteed to terminate. The algorithm, together with the order used to determine the leading term of each polynomial, are known to affect the cost of the computation, and are the focus of this thesis.

Abstract:

Aerobics dance floors often produce annoying floor vibrations in adjacent parts of a building due to the rhythmic impact of the aerobicists. Various types of shock absorbing aerobics and dance floors are widely used to prevent injuries to the participants, but the floors may not prevent vibrations in adjacent areas of the building. The purpose of this investigation is to evaluate a temporary "floating" concrete aerobics floor designed to prevent the force and vibrations induced by rhythmic exercises from being transmitted to the existing building floor system. The test floor is a concrete s

Abstract:

Every year, young adults graduate from high school and enter college. Often, college is the first opportunity students have to manage money. For some students, this means owning and managing their first credit cards. Colleges and universities frequently allow credit card vendors to solicit on campus. This practice is subject to criticism by the popular media, which reports horror stories of college students falling victim to great credit card debt. This study examined the credit card payment practices of college students at a large research institution. To explore the null hypotheses, a conv

Abstract:

The objective of this study is to investigate the application of Synchronized Phasor Measurement techniques in real time estimation of power system phasors. The WSCC System is a very large power system network constituted by a number of electric utilities and power companies. The system was analyzed and equivalents developed to suit the purpose of this project. Using these equivalents, the system was simulated for various contingencies to analyze its behavior. The purpose is to develop a technique for estimating the voltage phasors at all major substation buses of the system from a limited num

Abstract:

Experiments were carried out in a fixed-bed external recycle mixed flow reactor to measure the rate of dissolution and the development of a leached layer on wollastonite. Each experiment ran for approximately 24 hours and the release rates of Si and Ca in the interval from 14 to 24 hours were analyzed. Each experiment began with an incongruent stage where Ca was released faster than the silica that remained on the surface to form the leached layer. The silica release rate after 14 hours was 2.13 x 10-9 ( 1.03 x 10-9, 1 , n=67) mol/m2/sec, and this rate appeared to be independent of pH from pH

Abstract:

The conveyance of payloads by construction cranes generates pendulations of the payload. This research provides a critical design parameter for the development of a device that aids in reduction of these pendulations. Previous research developed a tuned mass damping system, that effectively attenuated the energy of a pendulating payload. In order to be effective the internal damping rate of the tuned mass damper must be at least twice that of the system to be damped. Prototypes of a tuned mass damping system have achieved damping rates between 6 and 12 %, making cranes with damping rates below

Full text

Abstract:

Methods of experimental analysis of airflow through an advanced-design, quasi-radial diffuser receiving an oscillating jet induced by a rotating baffle were devised and performed. The initially unsteady flow was found to lose its unsteadiness as it progressed through the diffuser and exited into the atmosphere. Within the diffuser, regions of slow flow in the lee of ventilation holes exist due to entrainment. The addition of a convergence insert across from these holes increased flow speeds, but also deflected the flow farther away from the holes, aiding separation. The predominantly steady fl

Abstract:

Traditionally, therapists and researchers have not asked adolescents about their family therapy experience. This qualitative study was designed to solicit in-depth feedback from adolescents who have recently participated in family therapy to broaden our understanding of their experiences in counseling. Interviews were conducted with 10 adolescents, between the ages of 14 and 20, to discover what helps teenagers have a successful family therapy experience. From the interviews, five main categories emerged; (1) client/therapist relationship, (2) talking and being heard in both individual and fam

Abstract:

Since about the turn of the decade, several proposals have come forth for personal communication services implemented by means of multiple satellite systems. These satellite systems are similar to current terrestrial cellular technologies, which are still relatively new and have numerous technical problems associated with them. As a result, these satellite systems will also experience some of the similar problems. Two of such problems are the issue of multipath and interference. These problems may result in significant link degradation and affect overall capacity. To overcome this problem, ada

Abstract:

We describe a system for tracking the motion and determining the velocity of the human eye using a combination of fiber optics and imaging optics integrated with a CCD camera, a framegrabber, and a PC. Systems such as the one we describe are needed for monitoring location of interest for better human-computer interfaces and virtual reality simulations, for monitoring pilot cognitive skills during flight simulations, and for detecting the early warning signs of driver drowsiness. Where some eye-tracking devices are cumbersome because they require a person to limit head motion to remain in view
