Abstract

In the southeastern United States, 'TifEagle' hybrid bermudagrass [Cynodon dactylon (L). Pers. x C. transvaalensis Burtt Davy] has become a selected cultivar for renovated or new bermudagrass putting greens, and its use has increased in popularity. However, there is limited research which examines TifEagle establishment, especially when cultural practices such as mowing height are included in the experimental design. The objective of this research was to evaluate the impact of N rate and mowing height on the percentage ground cover, shoot density, color, total nonstructural carbohydrate (TNC) content, and soil nitrate (N[O.sub.3]-N) and ammonium (N[H.sub.4]-N) content of TifEagle hybrid bermudagrass putting greens throughout three establishment years (2002, 2003, and 2004). Weekly applications of N were applied at 0.3, 0.6, 1.2, 2.4, and 4.8 g N [m.sup.-2] [wk.sup.-1], and mowing height applied at 3.2, 3.9, and 4.8 mm. Almost every agronomic measure (percentage ground cover, shoot density, root or rhizome and stolon mass, color) responded to increased applications of N, with maximum ground cover and shoot density reached at N rates from 3.4 to 4.3 g N [m.sup.-2] [wk.sup.-1]. Turf mowed under the lowest mowing height often had reduced turfgrass color and rhizome and stolon mass, compared with that mowed at 3.9 or 4.8 mm. Soil pH and residual N[O.sub.3]-N and N[H.sub.4]-N were almost always affected by N rate, but not by mowing height. For rapid establishment without significant reductions in shoot density, rhizome and stolon mass, and TNC, the highest N rate of 4.8 g N [m.sub.-2] [wk.sup.-1], as used in this study, was not needed.

Abstract

In this paper, the authors discuss the anticipated curriculum of electrical and computer engineering (ECE) programs in the year 2013 and beyond for a prototypical metropolitan public research university. Assumptions are made regarding the evolution of the relevant technology addressed by the curriculum, the nature of metropolitan public universities in the next decade, and the nature of the learning environment, technology, and educational focus based on present trends. A 128-credit-hour curriculum is proposed that addresses these challenges. Index Terms--Directions in electrical engineering education, engineering curriculum reform, future engineering education.

Abstract

Digital Landsat Thematic Mapper (TM) observations, multi-frequency polarimetric AIRSAR radar data, microtopographic profiles derived from helicopter-borne photography, and field measurements were analyzed over the Pisgah and Cima volcanic fields, and Lavic Lake playa, Mojave Desert, California. Surface radiance factors were extracted from TM data using radiative transfer procedures to model the atmosphere and surface simultaneously. AIRSAR data were calibrated to backscatter specific cross sections using corner reflectors deployed at a number of locations. Analyses focused on the use of key field sites to understand compositional and textural controls on TM band-5 (1.55 to 1.75 micrometer) radiance factors and C- (5.6 cm), L- (24 cm), and P- (68 cm) band specific cross sections. For the Pisgah and Lavic Lake sites, the TM data are explained using a linear mixing model of basalt and fine-grained sediment (clay to sand-sized grains of clay minerals, quartz, feldspar, carbonate, and lithic fragments) radiance factors, with the addition of shadows for the rough a'a flow. On the other hand, AIRSAR data are shown to be primarily controlled by surface roughness, as there is a strong correlation between specific cross section and surface height standard deviation. For the elongate flows at the Cima volcanic field, which exhibit a mix of pahoehoe and a'a properties, we find a positive linear relationship between TM band-5 radiance factors and flow ages for the 3 m.y. age range represented. Specific cross sections remain constant until about 0.14 Ma and then decrease with age up to about 0.56 Ma. On the other hand, data for the two older flows (0.70 and 0.85 Ma) show increasing specific cross sections with increasing age. We interpret the increase in TM band-5 radiance factors (from 0.05 to 0.25) with increasing flow age and the decrease in specific cross sections (8 dB change at 35 degrees incidence angle for L band) for flows up to 0.56 Ma in age as due to smoothing by mass wasting and infill by fine-grained aeolian deposits. The increased specific cross sections for older flows are interpreted to be a consequence of surface roughness generated by fluvial dissection.

Abstract

Measurements of diboson production cross sections in pp collisions at the LHC at a centre of mass energy √s = 7 and 8 TeV, and in pp̅ collisions at the Tevatron at √s = 1.96 TeV are reviewed and compared with standard model predictions. Limits on charged and neutral anomalous triple gauge couplings extracted from the selected diboson event samples are also compared.
