The performance characteristics of a diesel fuel piloted syngas compression ignition engine are presented in this thesis. A stock Hatz 1D81 engine was converted to operate in dual fuel mode through the elimination of the governor system and addition of an in-cylinder pressure transducer and custom intake system to facilitate the mixing of the gaseous fuel and combustion air. The engine was run on a Superflow water brake dynamometer and benchmarked with diesel to compare against manufacturer specifications. This was followed by dual fuel operation on methane and syngas, with the results being compared through performance characteristics. When operated on methane, the engine attained higher peak in-cylinder pressures along with higher torque, power, and thermal efficiency values for equal equivalence ratios. It was necessary to use greater amounts of syngas to reach comparable results with methane due to the lower energy content of syngas. The ignition delay was greater for syngas, and the onset of knock occurred earlier with syngas in comparison to methane. The heat release, Q, was comparable for both fuels and the exhaust gas emissions were significantly lower for operation with syngas. With emphasis on clean engine operation, syngas operation proved to be viable due to its renewable nature, significantly lower exhaust gas emissions, equal heat release characteristics, and larger useable operating range when compared to methane. / Thesis (Master, Mechanical and Materials Engineering) -- Queen's University, 2012-05-28 15:02:49.227

Quick feedback in regards to build times is important in Continuous Integration. If builds become too long, it can hurt the rate of software development. There are multiple methods to reduce build times. One commonly suggested method is to parallelize builds. This thesis aims to investigate the effects of parallelizing builds in Continuous Integration software and provide support for whether parallelizing is a good way of reducing build times or not. We conducted an experiment consisting of running tests on different Continuous Integration software with different configurations. These configurations changed how many tests were executed and how many parallel build agents were used. The aspects that were observed and analyzed was how build time, average CPU usage and CPU time were affected. What we found was that parallelizing a Continuous Integration build drastically improves build time, while RAM usage and CPU time remains similar. This entails that there are no major consequences to parallelizing other than utilizing more threads and therefore using more of the available CPU resources.

As turfeiras e os compostos org?nicos s?o materiais ricos em MOS. O objetivo do trabalho foi quantificar a capacidade de reten??o de ?gua da humina (H) e dos ?cidos h?micos (AH) da mat?ria org?nica (MO) de turfeiras e de composto org?nico proveniente de res?duos da ind?stria t?xtil, puros e em mistura com areia. O fracionamento dos materiais seguiu uma adapta??o da metodologia da Internacional Humic Substances Society. Obtiveram-se os substratos advindos das seguintes propor??es de subst?ncias h?micas (SH), provenientes de turfeira e de composto, e areia (fina e m?dia): 0 % SH e 100 % de areia fina (AF) e m?dia (AM); 100 % SH e 0 % de areia AF ou AM; 75 % SH e 25 % AF ou AM; 50 % SH e 50 % AF ou AM; 25 % SH e 75 % AF ou AM. Com o aux?lio do extrator de Richards foram determinados os teores de ?gua retida nas tens?es de 0 (CMRA), 10, 100, 300, 500, 700 kPa, para todos os substratos. Foi feita a an?lise de vari?ncia. N?o se observou diferen?as estat?sticas entre substratos com 100 % de AF e AM. Analisando-se as diferen?as de reten??o de ?gua dos substratos com 100% de AH e da H, e as diferen?as de origem (composto e turfeira), encontrou-se as maiores reten??es para os substratos com AH e para os substratos com SH provenientes de turfeira. A humina ? a SH que predomina amplamente no composto de res?duos de industria t?xtil e de turfeira. A maior reten??o de ?gua, na CMRA e nas tens?es 10, 100, 300, 500 e 700 kPa, foi obtida pelo substrato com 100% de AH em rela??o aos substratos com 100% de H. Os substratos com diferentes propor??es de AH e areia apresentaram reten??o de ?gua semelhante aos substratos com diferentes propor??es de H e areia. O substrato que obteve as maiores reten??es de ?gua foi 75 % de SH e 25 % de AF. Os AH e a H apresentam hidrofilia e tem potencial para a fabrica??o do hidrorretentor org?nico sustent?vel. Pela modelagem de reten??o de ?gua, a perda de ?gua pelos substratos ? base de H ? bem mais evidente na CMRA. Para os substratos ? base de AH a perda de ?gua com o aumento da press?o aplicada se torna mais evidente nas propor??es de 75 % de SH e principalmente, na CMRA. / Disserta??o (Mestrado) ?

Ocorrem predominantly in the North and Northeast of Brazil, mainly in the states of Par?, Amap?, Maranh?o and Tocantins. The pulp ju?ara, typical food of the region, if not consumed soon after obtaining it are packed in polyethylene bags and frozen. This project aimed to characterize and evaluate the mineral and organic content of the pulp ju?ara subjected to slow freezing and fast. Justified this research, to provide important information on the nutritional quality and functional that pulp, to contribute to improving the quality of life of Maranh?o, giving them a better quality of life, and to encourage the food industry. In this experiment we used ju?ara of ripe fruit (Euterpe edulis Martius) collected manually palm trees Ju?ara Park, located at Maracan? (within the island of S?o Lu?s-MA), in February 2012. The analyzes chemical, physical and physico-chemical pulp ju?ara revealed high in fiber, especially insoluble large percentage of lipids, anthocyanin, carbohydrates and low in protein. The minerals already analyzed the samples, the content of potassium, calcium, iron, zinc, copper, manganese and meet most of the recommended daily to man.The fatty acid composition showed a large amount of unsaturated fatty acids, predominantly oleic acid and palmitic acid. The number of microorganisms in the analyzed samples, lying within the standards required by applicable law in Brazil and the raw materials do not present significant hazards to the consumer, except in the case of molds and yeasts that are above the allowed amount. / A ju?areira (Euterpe edulis Martius) ? uma planta da fam?lia das Arecaceae (palmae), que desenvolve-se pr?ximo aos ribeir?es, rios, v?rzeas e nas matas de terra firme, e com menos frequ?ncia, em terrenos mais afastados e locais pantanosos.Ocorrem predominantemente nas regi?es Norte e Nordeste do Brasil, principalmente nos estados do Par?, Amap?, Maranh?o e Tocantins.

(no interior da ilha de S?o Lu?s-MA), em fevereiro de 2012. As an?lises qu?mica, f?sica e f?sico-qu?micas da polpa de ju?ara revelaram alto teor de fibras, em especial as insol?veis, grande percentual de lip?deos, antocianina, carboidratos e baixo teor de prote?na.
