Design and Analysis of Complex D-Regions in Reinforced Concrete Structures
No full textTo overcome these limitations, an experimental and computational program was conducted. This research aimed to generate the data needed for evaluating and validating the STM approach, for advancing STM shape selection techniques, and also to develop more reliable computational models for predicting the response of cracked structural concrete. In addition, a design and analysis framework that enables for automated nonlinear FEA design validation is proposed that integrates the current STM design provisions with two additional components: (1) the shape selection technique of STM based on topology optimization and (2) the new automated nonlinear FEA tool that was specialized for modeling and analyzing complex D-Regions.Made available in DSpace on 2015-09-25T21:04:46Z (GMT).

The Effects of Pitch, Vowel, Dynamic Level, and Gender on Nasalance in Amateur and Classically Trained Singers
No full textThe purpose of this study was to ascertain the effects of frequency range, vowel, dynamic level, and gender in amateur and classically-trained singers. Nasalance scores were obtained for 21 amateur singers and 25 classically-trained singers while singing an ascending 5-tone scalar passage in low, mid, and high ranges at both piano and mezzo-forte dynamic levels on each of the five cardinal vowels (/a/,/e/,/i/,/o/,/u/). A repeated mixed-model analysis indicated a significant main effect for the amateur/classically-trained distinction, dynamic level, and vowel, but not for range or gender. The amateur singers had significantly higher nasalance scores than classically trained singers on all vowels except /o/ when collapsed for all three ranges. The amateur singers also had significantly higher nasalance in each of the three ranges when scores for all vowels were combined for each range. Dynamic level had a significant effect on nasalance for the female subjects. For both amateur and classically-trained females, there was a significant difference between passages sung piano versus those sung forte. In the low and mid ranges, nasalance scores for female subjects were significantly higher in the passages sung piano. In the high range for female subjects, mezzo-forte passages received higher nasalance scores. In addition to vocal training and dynamic level, vowel had a significant effect on nasalance scores overall. For all subjects combined, /i/ received significantly higher nasalance scores when collapsed over all three ranges than all of the other vowels. The vowels /a/ and /e/ were not significantly different from each other, but were both significantly higher than /o/ or /u/. No significant difference existed between /o/ and /u/. Although results of this study show that certain variables in classical singing, such as vowel, range, and dynamic level, have a significant effect on nasality, it is important to note that only six of the subjects, all of whom were amateur singers, had average nasalance scores that could be considered hypernasal (i.e., a nasalance average above 22). This finding and the fact that classically trained singers consistently had less nasalance than amateur singers suggest that nasality does not play a prominent role in classical Western singing.Made available in DSpace on 2015-09-25T22:53:22Z (GMT).

Inheritance of Cold Temperature Emergence in Soybeans and Its Relationship to Field Emergence and Seed Yield of Early Planted Soybeans (Heritability, Genetic, Vigor)
No full textIncreasing use of reduced-tillage techniques, earlier planting, and late cold snaps can result in the exposure of emerging soybeans to suboptimal soil temperatures. Such exposure can result in decreased emergence, reduced seedling vigor, increased incidence of disease, and lowered yields. Soybean genotypes with superior cold temperature emergence (CTE) ability will avoid these problems.This study was conducted to determine the relationships of CTE ratings to field performance and seed yield of early-planted soybeans, and to quantify the inheritance of CTE.Seventeen adapted genotypes were screened for CTE in the laboratory for three years, and in the field for two years. Field performance of early-planted soybeans was related to CTE ability within years. Large seed source effects were observed.Significant genotypic variation for CTE was found among the F(,4) progeny of four soybean populations. Heritability estimates for CTE averaged 75%.Made available in DSpace on 2014-12-16T19:03:26Z (GMT). No. of bitstreams: 1

Aspects of Velvetleaf (Abutilon Theophrasti Medik.), Jimsonweed (Datura Stramonium L.) and Common Cocklebur (Xanthium Strumarium L.) Interference With Soybeans
No full textVelvetleaf (Abutilon theophrasti Medik.), jimsonweed (Datura stramonium L.) and cocklebur (Xanthium strumarium L.) are broadleaf weeds common in midwest soybean fields. Cocklebur causes greater yield reductions than velvetleaf and jimsonweed at equivalent densities. Cocklebur has a greater proportion of its leaves below the top of the soybean canopy where velvetleaf and jimsonweed have few to no leaves. Competititve effects of cocklebur may involve shading within the soybean canopy and space exclusion caused by its lower leaf canopy. Field and laboratory experiments were conducted to determine the causes for differences in leaf canopy of weeds below the top of the soybean canopy, to determine the importance of space exclusion and shading by weed leaves within the soybean canopy on soybean yield and other parameters, and to determine the cause for the apparent shade-tolerance exhibited by cocklebur.Cocklebur had more leaves below the top of the soybean canopy than the other species because of greater branch number and longer branches, contributing to greater axillary leaf development. Lower branch initiation and growth were inhibited in jimsonweed and velvetleaf grown next to the soybean row.Space exclusion combined with shading, simulated by cages covered with black plastic, caused increases in lodging, soybean height, height of bottom pod, and decreases in stem diameter, branches per plant, nodes per plant, pods per plant and soybean yield. Space exclusion without shading did not affect yield and affected fewer of the other parameters. Cocklebur utilized more space within the soybean canopy than did velvetleaf or jimsonweed due to its more developed leaf canopy. Shading within the soybean canopy may be a more important component in yield reductions caused by cocklebur than space exclusion.Ribulose-1,5-bisphosphate carboxylase (rubisco) protein per unit leaf volume decreased in cocklebur in response to a decrease in growth irradiance but the content of this enzyme was unaffected by the decrease in irradiance level in jimsonweed and velvetleaf. Lower rubisco content implicates lower synthesis costs if turnover rates of rubisco are equivalent among species. If so, the resulting savings in energy and nitrogen may contribute to the shade-tolerance exhibited by cocklebur.Made available in DSpace on 2014-12-16T19:03:38Z (GMT). No. of bitstreams: 1

Effects of Depth Variation of Substrate Dopant Impurity Concentration on the Interface Trap Density Determination in Mos Devices (Semiconductor)
No full textThe effect of dopant impurity concentration variation with depth on the interface trap density determination using the high-frequency capacitance-voltage (HFCV) or Terman method with a constant dopant concentration assumption has been quantitatively studied. A systematic correction scheme for nonconstant dopant concentration has been designed. Even if the substrate dopant concentration is not available, this correction scheme can still provide an estimation of the error in the interface trap density due to the nonconstant dopant concentration profile.The circuit technique for semiconductor analysis (CTSA) is employed to calculate ideal HFCV curves used in the Terman method. Theoretical error in the small-signal equivalent circuits for semiconductors due to the finite lump size has been analyzed. The discretization error of semiconductor capacitance in one single lump is found to be proportional to the cube of the lump size divided by the Debye length. The accumulated error in the flat-band semiconductor capacitance is proportional to the square to the lump size divided by the Debye length. It is shown that the lump size must be less than the Debye length to maintain accuracy in the small-signal equivalent circuit. Based on these results, a size selection rule of the discretization lump is proposed, which can consistently generate a grid system under a user prescribed accuracy requirement.The new analysis has been applied to estimate the errors in the interface and oxide trap densities generated during the avalanche electron injection stress of MOS capacitors. The results indicate that the errors caused by the nonuniform hydrogenated acceptor (boron) doping profile in the peaked donorlike interface trap density at 0.25 eV above midgap and in the turnaround of midgap voltage shift are very small.Made available in DSpace on 2014-12-15T19:05:12Z (GMT).
