This thesis is an examination of the problems that may arise from the location of S.T.O.L. airports within urbanized areas. The role of air transportation as a passenger travel mode is considered and the problems facing the existing air transportation system are explored. The potential role of S.T.O.L. aircraft within the air transportation system is examined in detail. Additionally, the benefits that may accrue from the use of S.T.O.L. aircraft in a regional air transport system are discussed extensively. The criteria to be used when looking for potential S.T.O.L. airport sites are examined in detail. These criteria are applied to three potential S.T.O.L. airport sites within the Vancouver urban area. In some cases the locational criteria were found to be difficult to operationalize. Data on community reaction to noise exposure is inadequate and noise standards are difficult to apply on a wide basis. The concept of land use compatibility around airports is useful but only to the extent that it does not obscure the fact that aircraft operations can cause community disruptions beyond the boundaries of the so-called compatible land uses. With specific reference to Vancouver, the available data indicates, that on the average, very little terminal access or egress time will be saved if a S.T.O.L. airport were built at a suitable location between the existing airport and the downtown area. Finally, the paper concludes by suggesting that despite the fact that S.T.O.L. aircraft cannot bring substantial time savings to regional air passengers, a S.T.O.L. air service may mean that many of the regions under utilized conventional airports could be converted to S.T.O.L. airports and yeild substantial savings in the money used to maintain and operate the publically owned airports in the province. / Applied Science, Faculty of / Community and Regional Planning (SCARP), School of / Graduate

Aim. The take-off is regarded as the most important phase of the pole vault yet there is an insufficient amount of research on the ground reaction forces of the pole vault takeoff. At this time there is not any scientific research comparing force and time between takeoffs that are out, on and under. The purpose of this study is to compare the differences in ground reaction forces between pole vault take-offs that are out, on or under. Methods. Over five days, 15 male and female college pole vaulters completed 226 vaults on a (AMTI Accupower) force plate. The jumps were put into categories of out, on and under and analyzed by Accupower, and Dartfish software. Separate mixed modal ANOVAs (SAS 9.3) were applied (P≤.05) for comparison between jump types. Conclusions. There is no significant difference between ground reaction forces of the three jump types.

Take-all is the most devastating root disease of wheat worldwide. The causal agent is <I>Gaeumannomyces</I> <I>graminis</I> (Sacc.) Arx & Olivier. Based on morphological characteristics and host ranges, three varieties of <I>G</I>. <I>graminis</I> have been recognized. <I>G</I>. <I>graminis</I> var. <I>tritici</I> Walker (Ggt) is the major causal agent of take-all of wheat and barley and the most economically important take-all pathogen. <I>G</I>. <I>graminis</I> var. <I>avenae</I> (Turner) Dennis (Gga) attack oats and causes take-all patch of turf grasses while <I>G</I>. <I>graminis</I> var. <I>graminis</I> (Ggg) is pathogenic on turf grasses but is non-pathogenic on wheat. Conventional diagnosis of take-all pathogens is based on field symptoms such as blackened roots, stunted growth, and white-heads and morphological characteristics such as hyphopodia type, size of perithecia, asci, and ascospores. These procedures are time-consuming, laborious, and often inconclusive. The objective of this study was to develop a rapid, simple, and specific method for differentiation of <I>G</I>. <I>graminis</I> varieties using PCR and molecular-based technology. Exploitation of genes associated with pathogenicity of <I>G</I>. <I>graminis</I> as markers for the test was proposed. Metabolic activities of <I>G</I>. <I>graminis</I> associated with pathogenesis were investigated, namely, the abilities to produce avenacinase and to oxidize manganese. Avenacinase, an avenacin detoxifying enzyme, was associated with Gga pathogenicity for oats but this enzyme is not important in Ggt pathogenicity for wheat. Manganese oxidation was also correlated with Ggt virulence. In this study, avenacinase-like genes were discovered in Ggt and Ggg and manganese oxidation was confirmed for Ggt, Gga, and Ggg. All isolates of Ggt except isolate ATCC 28230 were manganese oxidizers. Ggg and Gga isolates could oxidize manganese but their precipitation patterns were not as intense or closely correlated with mycelial growth as for Ggt. Pathogenicity assays on oats for Ggt, Gga, and Ggg isolates confirmed that Ggt isolates could not cause disease on oats aside from occasional slight root damage. Root weight was reduced for oat seedlings inoculated with Gga isolates. Comparison of partial sequences of avenacinase-like genes from Ggt and Ggg showed strong homology to that of Gga (94.8% identity to Ggt and 94.6% identity to Ggg). However, the Ggt gene was more closely related to that of Ggg (99.2% identity) than to Gga. DNA restriction endonuclease polymorphisms of the genes supported DNA sequencing information and revealed that there were variations within the genes among Ggt, Gga, and Ggg. Variety-specific electrophoretic patterns were obtained when the genes were digested with <I>Hae</I>III. Ggt, Gga, and Ggg upstream (5') variety-specific primers and a downstream (3') universal primer were designed from the avenacinase and avenacinase-like DNA sequences. PCR amplification with Ggt-, Gga-, and Ggg-specific primers generated fragments of 870, 617, and 1,086 bp, respectively. Each 5'-specific primer showed high specificity for its own DNA template in mixed populations of DNA templates. The optimized PCR procedure was sensitive to DNA template concentration as low as 100 pg. Genomic DNA of sixteen Ggt isolates, seven Gga isolates, and five Ggg isolates were tested. Although all Ggt isolates were originally isolated from wheat, seven isolates produced Ggg-specific fragments. This result corresponded well with <I>Hae</I>III DNA polymorphisms, pathogenicity assay, and manganese oxidizing ability. All but one Gga isolates produced the variety-specific fragment. Ggt- and Gga- specific products were generated from Gga isolate RB-W. Although Ggg-specific fragments were produced from all Ggg isolates, non-specific products were also observed from isolates that were not from wheat origin suggesting some genetic variations due to host ranges. Additionally, no non-specific amplification was obtained from any closely related fungi such as <I>Gaeumannomyces</I> <I>cylindrosporus</I> or <I>Phialophora</I> spp. The test developed in this study is the first test capable of identification of Ggt, Gga, and Ggg in a single PCR tube with a basic PCR protocol. The test is rapid and specific. Interpretation of results is simple and conclusive based on differences in size of each variety-specific fragment. / Ph. D.

The Winner-Take-All (WTA) is an essential neural network operation for locating the most active neuron. Such a procedure has been extensively used in larger application areas. The Winner-Take-All circuit selects the maximum of the inputs inhibiting all other nodes. The efficiency of the analog circuits may well be considerably higher than the digital circuits. Also, analog circuits’ design footprint and processing time can be significantly small. A current-based Winner-Take-All circuit for analog neural networks is presented in this research. A compare and pass (CAP) mechanism has been used, where each input pair is compared, and the winner is selected and passed to another level. The inputs are compared by a sense amplifier which generates high and low voltage signals at the output node. The voltage signal of the sense amplifier is used to select the winner and passed to another level using logic gates. Also, each winner follows a sequence of digital bits to be selected. The findings of the SPICE simulation are also presented. The simulation results on the MNIST, Fashion-MNIST, and CIFAR10 datasets for the memristive deep neural network model show the significantly accurate result of the winner class with an average difference of input and selected winner output current of 0.00795uA, 0.01076uA and 0.02364uA respectively. The experimental result with transient noise analysis is also presented.
