<p> The McMaster Incident Detection Algorithm <MacAlg> automatically detects incidents en the Burlington Skyway for the Burlington Freeway Traffic Managment System <FTXS>. This paper describes the calibration, testing and evaluation of functions of northbound stations 1 through 6. The testing and evaluation of the two weekly data sets is illustrated and discussed. Some of the resulting functions are recommended to the Burlingtion FTNS to evaluate how well the MacAlg detects incidents. This research compliments the work: of Persaud, Hall and Hall (1989), who are developing and testing the logic of the MacAlg. The results of this paper contribute information to the further development and testing of the MacAlg's logic. </p> / Thesis / Bachelor of Arts (BA)

St. Petersburg stood on the cusp of great change in 1946. Returning veterans sought jobs and housing, and St. Petersburg experienced its first major growth era since the real estate boom of the 1920s. The decade of the 1950s saw the city's population leap from 96,738 to 181,298, an 87 percent increase driven by boosters and national publicity about the city's leisurely ambience. Tract houses replaced remaining pockets of pasture and pine trees as subdivisions sprawled toward the city limits and beyond. On fertile truck-farming acreage called Goose Pond, developers built Central Plaza, a shopping center positioned to drain business energy from an aging downtown. Space-age industry brought light manufacturing to supplement traditional economic bases. The Sunshine Skyway opened in 1954 and less than a year later, road builders completed U.S. 19 through St. Petersburg, providing more economic advantages. Civil Rights advances shook Jim Crow, as African Americans sued to integrate swimming venues and challenged "red lines" defining where people of color could live and open businesses. Television began opening new horizons and changing leisure habits as air conditioning brought residents a new dimension of indoor comfort. City leaders reaching for a dynamic civic image worried about the city's reputation as a haven for the elderly, but education leaders ordered three new high schools built to serve the burgeoning white student population. The mid-century boom revived an optimistic spirit while raising issues such as land use, the downtown's future, and race relations against a backdrop of cultural change and the search for civic identity. As reflected in articles, interviews, reports, and manuscripts, St. Petersburg began redefining itself for the twentieth century's second half. This study surveys, describes, and analyzes the transformative events.

Tidally-influenced sandwaves are common coastal features present in various settings, including shipping channels. The main shipping channel in Tampa Bay under the Bob Graham Sunshine Skyway Bridge (a.k.a. the Skyway Bridge) contains such sandwave bedforms. Between the years 2000 and 2017, these bedforms have been surveyed with multibeam echosounders (MBES) on 21 occasions with ranging coverage and quality of returns. Surveys between 2000 and 2009 used a 300 kHz Kongsberg EM3000; surveys between 2015 and 2017 used a 400 kHz Reson Seabat 7125. For comparable surveys, bathymetry, backscatter, slope, curvature, planform curvature, and profile curvature maps were created and analyzed. Spectral analyses were completed on the same cross-section for usable surveys, providing a period and amplitude for the bedforms. Sediment samples were taken in September 2015 using a Shipek grab. The sediment samples were analyzed for grain size and carbonate content. A bottom-mounted ADCP recorded velocity data semi-continuously over the same time period. These data were analyzed in an effort to investigate the forcing mechanisms that influence the bedform morphology. Mean grain sizes in the shipping channel under the Skyway Bridge range from 0.01 φ (0.99 mm, coarse sand) to 1.55 φ (0.34 mm, medium sand). Calcium carbonate content ranges from 25% to 87%. The sediment sample site most representative of the sandwave bedforms has a mean grain size of 0.01 φ and a calcium carbonate content of 87%. The calculated mean current velocity required to initiate transport of the D50 and D84 grain size percentile of the representative sediment sample site is 0.70 m/s and 1.05 m/s, respectively. Analysis of the ADCP-recorded velocity data shows that the calculated D50 critical velocity is frequently reached by peak flood and peak ebb currents except during neap tides, while the D84 critical velocity is reached only intermittently, mostly during spring tides. Analysis of MBES backscatter shows similar spatial patterns in two larger MBES surveys in 2004 and 2015. Bathymetric analysis of the sandwaves shows consistent characteristics through time. Wave crest analysis reveals that bedforms migrate in both the ebb and flood directions. Spectral analysis shows primary wave spatial frequencies range from 0.13 m-1 to 0.22 m-1, and primary wave periods range from 4.5 m to 6.0 m. The predominant wavelength of sandwaves within the study area is about 5 m, with an average wave height of 0.47 m. The maximum wave height along the axial cross-section analyzed is 0.8 m, observed in April 2017. The sediments comprising the sandwave bedforms are likely winnowed by tidal currents resulting in larger grain size and carbonate content than other areas of the shipping channel and surrounding bay. Consistent patterns in MBES backscatter over time indicate that the sediment distribution pattern in the study area have not significantly changed. The size and shape of the bedforms in the shipping channel beneath the Skyway Bridge are have been in a quasi-dynamic equilibrium over the past 13 years. The bedforms are shown to migrate in both the ebb and flood directions despite an average faster ebb current velocity than a flood current velocity. More frequent and consistent MBES surveys as well as more continuous ADCP data availability would allow for better understanding of sediment transport via bedform migration in tidally-influenced environments.

Esta investigación es una teoría crítica del arte en la forma urbana. Propone un conjunto de términos y operaciones claves consolidados entorno al binomio 'arte-público', presentando este como meta-modalidad de la emancipación ciudadana basada en la estética de lo social. Concluye que la retórica, con su estructuración ethos/logos/pathos, es la racionalidad total que concretiza una concientización plástica de los valores proyectuales de la atención, del dispositivo y de la gracia. Estos son considerados fundamentales en una experiencia emancipada de la ciudad. En la Parte I, se explicitan las consecuencias de varios movimientos críticos en las vanguardias artísticas y urbanísticas, y en el ensayo de la crítica cultural. En el regimen del arte contemporáneo, destaco figuras y modos del viraje conceptual al land art, sedimentando una gramática del arte en el Espacio Público. Tres binomios condensan la problemática: Museo, intervención (la intervención urbana como propuesta de otra memoria y representación de lo colectivo); Contexto/situación (la situación como corolario de una consciencia de lo efímero y lo contextual; Activismo/participación (el activismo como modalidad de la participación comunitária). Se intenta abordar la jerga del arte público contemporáneo en orden a problematizar radicalmente la cultura urbana, en el contexto de un urbanismo general continuamente emergente. En el Parte II, se analiza los casos de estúdio LISBOA CAPITAL DO NADA - MARVILA 2001, SINAIS, A CIDADE HABITADA, LUZBOA (todos eventos en Lisboa) y SKYWAY (en Polónia). En esta secuencia de experiencias curatoriales, las intervenciones artísticas, separadamente y entanto dinámica integrada, definen un conjunto de valores, actitudes e ingenuidades que desvelan una estética. / Da Cámara De Melo Caeiro, MJ.
