Partindo desta premissa, este trabalho foi desenvolvido em área de produção de cana-de-açúcar no município de Pradópolis - SP, com o objetivo avaliar a qualidade operacional do plantio mecanizado de cana-de-açúcar em sistema meiosi, utilizando-se de ferramentas do controle estatístico de processo. O delineamento utilizado foi inteiramente casualizado em faixas, com 3 tratamentos (velocidades de deslocamento dos conjuntos mecanizados de 4, 5 e 6 km h-1) e 10 repetições. Foram avaliados parâmetros biométricos relacionados ao plantio e à colheita de mudas, ao desempenho dos conjuntos mecanizados, e também os resultados de brotação do canavial aos 30, 60 e 90 dias após o plantio. O controle estatístico mostrou ser uma importante ferramenta para monitorar o comportamento das variáveis analisadas, sendo uma maneira de se aprimorar o controle das variáveis no processo de plantio. Os processos foram considerados instáveis quando avaliadas as variáveis biométricas do plantio, em que a velocidade de 4,0 km h-1 apresentou maior variabilidade seguida das velocidades de 5,0 km h-1 e 6,0 km h-1. O aumento de 50% na velocidade no sistema meiosi não afetou a qualidade da operação de plantio, sendo possível trabalhar nas velocidades de até 6,0 km h-1 para se obter maior capacidade de campo operacional / The system MEIOSI (methods Interocupacional Occurring Simultaneously) is a new form of sugarcane renewal that has gained importance as a means to reduce production costs, by crop rotation with soybeans.

The experimental design was completely randomized in “strips”, with three treatments (speeds of machinery 4, 5 and 6 km h-1. Biometric parameters were evaluated related to planting and harvesting of plants, the performance of machinery, and also results in sprouting of sugarcane at 30, 60 and 90 days after planting. The statistical control was an important tool to monitor the behavior of the variables, being a way to enhance the control of variables in the process of planting. The cases were considered unstable, when measured variables biometric planting, in that the speed of 4 km h-1 showed greater variation then the speed of 5 and 6 km h-1. The 50% increase in speed in meioisi system didn’t affect the quality of the planting operation, and can work at speeds of up to 6 km h-1 for greater performance in field operations

<p>This thesis presents several module systems, in particular Mei and DMei, designed for mechanized mathematics systems. Mei is a λ-calculus style module system that supports higher-order functors in a natural way. The semantics of functor application is based on substitution. A novel coercion mechanism integrates a parameter passing mechanism based on theory interpretations with simple λ-calculus style higher-order functors. DMei extends Mei by supporting dependent functor types. Mei is the first module system that successfully supports both higher-order functors and a parameter passing mechanism based on theory interpretations.</p> / Thesis / Doctor of Philosophy (PhD)

Master of Agribusiness / Department of Agricultural Economics / Allen M. Featherstone / The purpose of this thesis is to analyze the impact the installation of an automated packaging system would have on the predominately manual bulk packaging work centers at Wixon Inc., a privately held, integrated food and beverage developer, manufacturer, and processor. The objective of this thesis is to determine if converting to an automated system would minimize costs and increase line speeds. The owners desire a 3-year payback on the investment. In addition to the financial and economical aspects of automating the equipment, there are potential food safety and personnel safety improvements that would be brought to the firm by changing equipment. The firm’s owners want to be proactive and minimize any impact a reduction in the labor pool might see cause from the exit of workers from the Baby Boomer generation. Methods used to determine the objectives of this thesis include a comparative time study of bag filling rates, an analysis of incremental cost savings, net present value (NPV) analysis and return on investment (ROI). Data were collected from studies conducted by the engineering consulting firm of Middough Incorporated, from Wixon Inc. accounting records and, interviews of key Wixon employees. The report provided by Middough determined that the new system would be able to replace three work centers in the Bulk Packaging department based on bag fill rates and flexibility in bag sizes. This reduces the employee cost per bag. The incremental costs were analyzed using accounting records for past history. Floor space, labor costs and other integral costs were compared to determine what costsavings there may be. Cost savings were treated as cash flow. The NPV and ROI for the project used this cash flow to determine if an investment in automation is a wise one. The conclusion based on the analysis made was that, based on NPV the investment would be profitable. However, the 3-year payback of $1.5 million would not be possible under current assumptions. The automation would reduce the number of needed employees enough to absorb any reduction in the labor pool while providing increased food and employee safety.

A produtividade média da mamona em bagas no Brasil tem sido muito baixa, cerca de 440 kgha-1, devido ao baixo nível tecnológico empregado pelos produtores e pela baixa oferta de cultivares selecionadas para alta produtividade de grãos, além da falta de híbridos para colheita mecanizada. O objetivo do trabalho foi obter novos híbridos de mamona e avaliar suas características agronômicas, principalmente relacionadas à produtividade e porte da planta para colheita mecanizada. Para obtenção dos híbridos foram utilizadas quatro linhas femininas e 72 linhagens masculinas. A avaliação dos híbridos foi dividida em dois experimentos, sendo o primeiro instalado em 21 de outubro de 2005 e o segundo em 07 de dezembro de 2005. Além desses híbridos foram avaliados como testemunha os híbridos comerciais Íris e Savana. Os experimentos foram conduzidos sob delineamento experimental de blocos ao acaso, com 3 repetições. As parcelas experimentais foram constituídas de uma linha de 6 m, com espaçamento de 0,6 m entre plantas, 1,0 m entre linhas e área útil de 6m2. Os dados obtidos foram submetidos à análises de variância e as médias comparadas pelo teste F e pelo teste de Scott-Knott a 1% de probabilidade, utilizandose o programa SISVAR v.4.2. As características avaliadas foram produtividade de grãos, altura de plantas, porcentagem de flores femininas no racemo primário, teor de óleo das 2 sementes, altura de inserção do racemo primário, número de internódios até o racemo primário, produtividade de grãos do racemo primário e massa de 100 grãos. Com base nas análises de variância foram observadas significâncias para todos os parâmetros avaliados, nos dois experimentos.

In Brazil castor bean grain yield has been very low, 440 kgha-1, and this fact may be explained by low technologies levels applied, absence of selected genotypes for high yield and the absence of hybrids for mechanized harvesting. The objective of this work was to obtaining castor bean new hybrids and to evaluate agronomic characteristics specially grain yield and plant height to mechanized harvesting. For obtaining the hybrids it was used four pistilates lines and 72 male lines. Two experiments were conducted to evaluate the hybrids, the first experiment was set in October 21st/2005 and the second one in December 7th/2005. Beyond these hybrids it was evaluated commercial hybrids, Iris and Savana, as control. The experiments were conducted under randomized complete blocks experimental design with three replications. The experimental plots were constituted by one row with 6 m, space of 0,6m between plants and 1,0m between lines, comprehending 6m2 of total area. Results were submitted to variance analysis and means compared by F test and Scott-Knott test with 1% of probability through SISVAR Program, 4.2 version. The characteristics evaluated were yield of seeds, plant height, percentage of pistilate flowers, oil content of seeds, height of primary raceme insertion, number of internodes until primary raceme, yield of grains of primary raceme and mass of 100 grains. 4 Based on variance analysis it was observed that the mean squares were significant for al characteristics in both experiments. In experiment 1 a considerable number of hybrids were superior to the controls, for grain yield, and 28 and 30 hybrids were the most productive. No one of the control overcame the general average of grain yield. It was observed that... (Complete abstract, click electronic access below)
