Influência de uma piscicultura em tanques rede na qualidade da água do Rio São José dos Dourados no município de Ilha Solteira/SP /Previato, Vanderlei. January 2009 (has links)
Orientador: Sérgio Luís de Carvalho / Banca: Alessandro Minillo / Banca: Cristiano Poleto / Resumo: A quantidade de água potável no mundo esta diminuindo em virtude de sua utilização para fins residenciais, agrícolas, industriais e comerciais, enquanto que a opulação mundial esta aumentando. O presente trabalho teve por objetivo proceder à avaliação da qualidade da água sofrendo influência de uma piscicultura em tanques rede no Rio São José dos Dourados no Município de Ilha Solteira. O rio São José dos Dourados nasce no município de Mirassol-SP a 587 metros de altitude, localizado a uma latitude de 20°49'09" sul e uma lontifude 49°21'16" oeste, desaguando no rio Paraná. Corta o município de Ilha Solteira e hoje esta ligado ao Tiete pelo canal de Pereira Barreto que incorporou os 400 Km do tramo norte à Hidrovia Tietê-Parana. Sua bacia é constituída de aproximadamente 35 afluentes e 25 municípios em toda a sua extensão. No seu curso normal, deságua no Rio Paraná, a uma longitude de 51°06'35" e latitude 20°38'44". A partir dos resultados do Índice de Qualidade de Águas será possível verificar os efeitos dessa atividade sobre a qualidade da agua, principalmente, em função da elevação dos fertilizantes (fósforo e nitrogênio). No presente trabalho propoe-se verificar a influência da piscicultura em tanques rede na qualidade da água do Rio São José dos Dourados, onde amostras de água foram colhidas em sete pontos, sendo dois pontos no meio do rio, sem a inflencia da psicultura, coletados durante os meses de janeiro a agosto de 2008, sendo confeccionado com este o Índice de Qualidade da Água da National Station Fundation dos Estados Unidos, adaptados pela CETESB / Abstract: Potable water availablein the world is being gradually reduced due to is use in households, commerce, agriculture and industry while global population is increasing. The main purpose of this work is to e valuate the water quality in an enviromental of the net-tank fishing culture in São José dos Dourados River in the city of Ilha Solteira. São José dos Dourados River borns in Mirassol - SP at 587m altitude, 20 9'09" sout h latitude and west longitude 49º31'16", flowing towards the Paraná river. It crosses the city of Ilha Solteira and actually is connected to Tietê River through the chanel of Pereira Barreto which added 400 km of the North opening to Tietê-Paraná waterway. Its basin is formed by approximately 35 tributaries and 25 cities in all its extension. In the normal running it recedes in Paraná River at 51º06'35" longitude and 20º38'44" latitude. As of the results of Water Quality Index it will be possible to check the effects of this activity over the water quality, mainly due to the increasing use of fertilizers (phosphorus and nitrogen). In this research, it is proposed to check the effects of the net-tank fishing culture over the water quality in São José dos Dourados River, where water samples were collected in seven different points, 2 of them in the middle river without the influence of fishing activity from January to August 2008. These samples were used to prepare the Water Quality Index of National Sanitation foundation of United Stares, adapted by CETESB / Mestre

Utvärdering av arbetsprocess och CMSPettersson, Douglas January 2017 (has links)
I dagens webb används ofta många olika innehållshanteringssystem för att göra det enkelt för användare att hantera deras egna hemsidor. I utvecklingsarbetet hos webbyråer bedrivs även någon typ av projektledning. Syftet med denna undersökning är att utvärdera och analysera ett företags befintliga CMS och deras arbetsprocess. Denna utvärderingen kommer göras utifrån ett visst antal kriterier som är kännetecken för olika projektledningsmetoder samt en separat utvärdering för ett passande CMS utifrån specifikationer och intervjuer. Här kommer faktorer som licens, funktionalitet, plattformsstöd, vidareutveckling, popularitet samt exempelvis programmeringsspråk. Denna undersökning visade på att företaget arbetar med ett agilt arbetssätt, samt att deras befintliga CMsystem är det optimala för deras verksamhet för att de ska upprätthålla sina möjligheter att helt skräddarsy lösningar och ha full kontroll på produkten.

Previous issue date: 2008 / Linguagens funcionais se destacam pelo seu alto poder de expressão e
abstração, promovido por construções de alto nível como polimorfismo
paramétrico, funções de alto nível e aplicações parciais. Embora estes recursos
sejam bastante úteis, tradicionalmente, linguagens funcionais têm sido pouco
empregadas fora do ambiente acadêmico. Esta situação é em parte explicada
pela ausência de uma infra-estrutura de desenvolvimento que forneça ferramentas
e APIs capazes de aumentar a produtividade e permita o uso das mais recentes
tecnologias.
Uma alternativa para fornecer esta infra-estrutura é integrar linguagens
funcionais a plataformas que disponibilizem tais facilidades, como a .NET. Embora a
plataforma .NET tenha sido projetada de forma a suportar múltiplas linguagens, seu
foco foi dado ao suporte dos paradigmas imperativo e orientado a objeto,
carecendo de estruturas que permitam um mapeamento direto de linguagens
funcionais.
Objetivando estudar novas técnicas de mapeamento de estruturas
funcionais na plataforma .NET, neste trabalho foi desenvolvido um compilador
funcional que gera código .NET, utilizando o framework Phoenix. O uso do
framework Phoenix além de auxiliar na geração inicial do código permitiu que
análises e otimizações fossem feitas, posteriormente, melhorando o desempenho
dos programas gerados

Sustenance Organization and the Repopulation of Nonadjacent Nonmetropolitan Counties in the State of Texas, 1970-1980Nissen, Timothy E. (Timothy Edward) 05 1900 (has links)
From 1970 to 1980 nonadjacent counties in Texas experienced an increase in net migration of 9.4 percent, significantly different from the 11.8 percent decrease experienced the previous decade. This study utilized the ecological perspective to study this redistribution pattern in Texas' nonadjacent counties between 1970 and 1980. Sustenance organization, defined as sustenance differentiation (the functional organization of sustenance activities and the dispersion of workers across these functional categories) and the mode of sustenance organization (the combinations of various sustenance activities) was identified as the primary independent variable. In addition, three secondary independent variables were included in the analysis (population per square mile, metropolitan dominance, and the percent who work outside the county of residence).

A feasibility study of the expansion of swine and management for Iowa State University’s AG 450 farmRinker, Skyler P. January 1900 (has links)
Master of Agribusiness / Department of Agricultural Economics / Allen M. Featherstone / For more than 70 years, the Iowa State University Ag 450 Farm has been in operation south of the Iowa State University (ISU) campus located in Ames, Iowa. The Ag 450 farm is currently the only student managed farm at a land grant university in the United States. The idea for the Ag 450 Farm was developed by Dr. William Murray in 1938 and in 1943, the Ag 450 class was first offered by Dr. Murray.
At the farm, the core principals of agribusiness and farm management have been taught while adapting to an ever-changing agriculture. The Ag 450 Farm is considered the capstone course for the Iowa State University Agricultural Studies major. ISU Ag 450 is currently under the supervision of farm manager Greg Vogel and the Iowa State University Agriculture and Studies Department.
Today, the Iowa State University Ag 450 students manage approximately 275 acres of owned ground, 700 acres of cash rented ground, 80 acres of crop share ground, and 800 acres of custom farmed ground depending on the year. Ag 450 represents a commercial farming enterprise of corn and soybean production as well as housing nursery piglets and custom finishing over 1000 head of feeder pigs.
In its current condition, the ISU Ag 450 is looking to expand its operations to meet the demands Agricultural Studies majors at Iowa State University. A focus of the expansion is to increase the amount of custom finished feeder pigs by building another finishing facility. That type of expansion requires the need for another full-time farm manager. This research examines the feasibility of expansion of the swine and management to determine the impact this may have on the future viability of the farm.

Performance evaluation of J2EE & .NET web services interacting with a .NET clientNakka, Raja Sanjeev Kumar January 1900 (has links)
Master of Science / Department of Computing and Information Sciences / Daniel A. Andresen / The objective of this project is to build an e-commerce website using ASP.NET as well as J2EE technologies. Visual Studio 2005 provides a great IDE to build seamless front end layer for the websites with minimum effort. Hence, it is used to build the presentation layer. The business logic layer is developed in ASP.NET 2.0 and J2EE, exposing the functions as web services. Two similar clients have been developed in ASP.NET. These two clients invoke the .NET and J2EE web services.
The two similar websites are subjected to testing for correctness and performance. Stress and load testing is performed thoroughly on the website. A detailed analysis of the results is done using the response times and throughputs from various tests.
This report proves that we can build a website using a presentation tier developed in ASP.NET consuming any of the two technologies’ (ASP.NET & J2EE) web services. This proves to be very useful in scenarios where we need the best overall user experience regardless of the technology, to replace or extend an existing business tier by using a different technology.

Formal Modeling and Analysis Techniques for High Level Petri NetsLiu, Su 20 June 2014 (has links)
Petri Nets are a formal, graphical and executable modeling technique for the specification and analysis of concurrent and distributed systems and have been widely applied in computer science and many other engineering disciplines. Low level Petri nets are simple and useful for modeling control flows but not powerful enough to define data and system functionality. High level Petri nets (HLPNs) have been developed to support data and functionality definitions, such as using complex structured data as tokens and algebraic expressions as transition formulas. Compared to low level Petri nets, HLPNs result in compact system models that are easier to be understood. Therefore, HLPNs are more useful in modeling complex systems.
There are two issues in using HLPNs - modeling and analysis. Modeling concerns the abstracting and representing the systems under consideration using HLPNs, and analysis deals with effective ways study the behaviors and properties of the resulting HLPN models. In this dissertation, several modeling and analysis techniques for HLPNs are studied, which are integrated into a framework that is supported by a tool.
For modeling, this framework integrates two formal languages: a type of HLPNs called Predicate Transition Net (PrT Net) is used to model a system's behavior and a first-order linear time temporal logic (FOLTL) to specify the system's properties. The main contribution of this dissertation with regard to modeling is to develop a software tool to support the formal modeling capabilities in this framework.
For analysis, this framework combines three complementary techniques, simulation, explicit state model checking and bounded model checking (BMC). Simulation is a straightforward and speedy method, but only covers some execution paths in a HLPN model. Explicit state model checking covers all the execution paths but suffers from the state explosion problem. BMC is a tradeoff as it provides a certain level of coverage while more efficient than explicit state model checking. The main contribution of this dissertation with regard to analysis is adapting BMC to analyze HLPN models and integrating the three complementary analysis techniques in a software tool to support the formal analysis capabilities in this framework.
The SAMTools developed for this framework in this dissertation integrates three tools: PIPE+ for HLPNs behavioral modeling and simulation, SAMAT for hierarchical structural modeling and property specification, and PIPE+Verifier for behavioral verification.

Effects of Horticultural Oils on Photosynthesis, Fruit Maturity, and Yield of Wine GrapesFinger, Sarah Adine 26 May 2000 (has links)
In field experiments conducted in northern Virginia during 1998, oils reduced photosynthesis, fruit maturity, and crop yield. Three applications of a 1.5% (v/v) oil/water emulsion were made to Chardonnay and Cabernet Sauvignon vine canopies at 6200 L/ha (Chardonnay) and 2440 L/ha (Cabernet Sauvignon). Net assimilation rate (NAR), soluble solids concentration (SSC), and berry size were reduced by oil treatments when compared to an untreated control. Also in 1998, a 1.5% (v/v) oil/water emulsion at 5550 L/ha and 4680 L/ha was applied to 23 wine grape cultivars. Eleven cultivars had significant foliar injury but injury was not related to reductions in fruit maturity. Experiments conducted in 1999 determined if reduced spray volumes or applications to only the fruit zone minimize reductions in NAR and SSC. Chardonnay and Cabernet Sauvignon were treated with JMS Stylet oil (1.5%) using 5600 L/ha or 1870 L/ha applied to the whole canopy or 930 L/ha applied to the fruit zone. The NAR of 5600 L/ha treated Cabernet Sauvignon was significantly lower than the NAR of control and other oil treatments on three measurement dates. The NAR of Chardonnay in the 5600 L/ha treatment was significantly lower than the NAR of control treatments in three measurements. Cabernet Sauvignon SSC was reduced by the 5600 L/ha and 1870 L/ha treatments, relative to the water treated control, on three sample dates but not at harvest. The SSC of Chardonnay in the 5600 L/ha treatment was reduced at harvest as compared to all other treatments. The SSC of Chardonnay in the 1870 and 930 L/ha treatments was reduced relative to the water control. Low volumes of oil caused less reduction in NAR and SSC; however, there are concerns about the efficacy of oils used at low volumes due to poor coverage. / Master of Science
