Separation and Execution of graphical engine on a cross platform IDE to enhance performance

“Biosim” is a simulation software which works to simulate the harvesting system.This system is able to design a model for any logistic problem with the combination of several objects so that the artificial system can show the performance of an individual model. The system will also describe the efficiency, possibility to be chosen for real life application of that particular model. So, when any one wish to setup a logistic model like- harvesting system, in real life he/she may be noticed about the suitable prostitution for his plants and factories as well as he/she may get information about the least number of objects, total time to complete the task, total investment required for his model, total amount of noise produced for his establishment in advance. It will produce an advance over view for his model. But “Biosim” is quite slow .As it is an object based system, it takes long time to make its decision. Here the main task is to modify the system so that it can work faster than the previous. So, the main objective of this thesis is to reduce the load of “Biosim” by making some modification of the original system as well as to increase its efficiency. So that the whole system will be faster than the previous one and performs more efficiently when it will be applied in real life. Theconcept is to separate the execution part of ”Biosim” form its graphical engine and run this separated portion in a third generation language platform. C++ is chosenhere as this external platform. After completing the proposed system, results with different models have been observed. The results show that, for any type of plants of fields, for any number of trucks, the proposed system is faster than the original system. The proposed system takes at least 15% less time “Biosim”. The efficiency increase with the complexity of than the original the model. More complex the model, more efficient the proposed system is than original “Biosim”.Depending on the complexity of a model, the proposed system can be 56.53 % faster than the original “Biosim”.

Políticas de empregabilidade: o estado da arte na virada do século

O crescimento do desemprego involuntário condiciona preocupações recentes com políticas de empregabilidade. Estratégias na regulação do mercado de trabalho e a terceira geração na Teoria do Capital Humano buscam codificar e/ou equacionar essas políticas. O surgimento do conceito de Economia Plural oferece uma revisão para a dinâmica do setor informal, tradicional ou moderno, na geração de empregos atípicos. A noção de Economia Plural ressalta também o papel catalizador das empresas sociais e organizações não governamentais na reinserção dos excluídos sociais. As flexibilizações do tempo de trabalho em políticas de empregabilidade são desenvolvidas através de reflexões, impactos comportamentais na qualidade de vida e experiências negociadas nos setores metalúrgico, de distribuição e de prestação de serviços de saúde. Desafios se colocam para o poder público e entidades de classe na regulamentação e ou negociações da empregabilidades atípica.

Os fatores que influenciam a implementação das boas práticas da governança corporativa nas empresas familiares

Este estudo de caso tem como objetivo investigar quais são os fatores que influenciam a implementação das boas práticas da governança corporativa nas empresas familiares. A partir de uma abordagem qualitativa de pesquisa, adotou-se como método o estudo de caso único. Como instrumento de pesquisa recorreu-se a utilização de entrevistas semi-estruturadas com membros da família proprietária da segunda e terceira geração, representantes do Conselho de administração, sócios atuantes e não atuantes. Para o tratamento dos dados, recorreu-se à análise do conteúdo das entrevistas. Para fundamentar a pesquisa, houve a necessidade de uma revisão bibliográfica envolvendo governança corporativa; empresas familiares e suas particularidades; governança corporativa em empresas familiares e fatores que influenciam e dificultam o processo de implementação das boas práticas de governança corporativa à luz da literatura. A pesquisa aqui apresentada foi realizada na empresa Casa do Alemão Indústria e Comércio de Lanches LTDA, do setor alimentício, que se encontra sob comando da segunda e terceira geração da família fundadora, tendo como dominante a segunda geração. Os resultados obtidos nesta pesquisa apontam que as boas práticas de governança corporativa estão parcialmente presentes na Organização e que para uma implementação por completa, é necessário reformular os elementos já existentes e a criação de novas medidas de governança para melhorar a objetividade nos processos de qualificação, gestão, decisão e sucessão. Os fatores considerados como influentes e positivos para a implementação por completa das boas práticas de governança corporativa nesta Organização são: cultura de transparência; separação do patrimônio pessoal e empresa; predisposição de todos os sócios pela aceitação a utilização de processos mais formais na forma de trabalho. Dentre outros motivos ainda não implementados e que poderiam ser elementos influentes para a implantação são: necessidade de enfrentar os conflitos familiares; custos (investimento); resistência das pessoas (interesses divergentes dos sócios, família, executivos) e mais monitoramento (pessoas não gostam de ser monitoradas e avaliadas). Apesar de carregar a experiência que o tempo atribui aos sexagenários, a empresa também demonstra a agilidade da juventude para se manter com um visual moderno e iniciar uma nova política de expansão.

Metagenômica comparativa de solo de regiões de mata atlântica e caatinga do estado do Rio Grande do Norte - Brasil

The microorganisms play very important roles in maintaining ecosystems, which explains the enormous interest in understanding the relationship between these organisms as well as between them and the environment. It is estimated that the total number of prokaryotic cells on Earth is between 4 and 6 x 1030, constituting an enormous biological and genetic pool to be explored. Although currently only 1% of all this wealth can be cultivated by standard laboratory techniques, metagenomic tools allow access to the genomic potential of environmental samples in a independent culture manner, and in combination with third generation sequencing technologies, the samples coverage become even greater. Soils, in particular, are the major reservoirs of this diversity, and many important environments around us, as the Brazilian biomes Caatinga and Atlantic Forest, are poorly studied. Thus, the genetic material from environmental soil samples of Caatinga and Atlantic Forest biomes were extracted by direct techniques, pyrosequenced, and the sequences generated were analyzed by bioinformatics programs (MEGAN MG-RAST and WEBCarma). Taxonomic comparative profiles of the samples showed that the phyla Proteobacteria, Actinobacteria, Acidobacteria and Planctomycetes were the most representative. In addition, fungi of the phylum Ascomycota were identified predominantly in the soil sample from the Atlantic Forest. Metabolic profiles showed that despite the existence of environmental differences, sequences from both samples were similarly placed in the various functional subsystems, indicating no specific habitat functions. This work, a pioneer in taxonomic and metabolic comparative analysis of soil samples from Brazilian biomes, contributes to the knowledge of these complex environmental systems, so far little explored

O desenvolvimento sustentável na ordem constitucional e sua promoção através do planejamento urbano

The man, being subject and object of their changes, has passed by many process to find a better life way. Since your existence, he finds to live in groups for make easy your life and make concrete yours desires. All by history, when the individual´s rights was establishment, collectives and lonely way, contribute for evaluate the relationship between individuals and they own, and them and state, which has a duty to those, positive or negative, depending on the case. The circle of fundamentals rights has been sustainable development and the concept of growth economy associated to the environment protection. This association reflect a apparent conflict between values very distinct, but the constitutional interpretation can be reunite both of them and make it live in harmony; values of environmental order and economical order can be exist together, as long as the state contribute to this. On the city, where the most of relationships happening, the urban plan appear how a effective way of sustainable development, finding the harmony between the growth economy and environment protection. To effective the socials functions of the city (inhabit, circulate, work and entertainment) and the citizen´s life quality, the city is the scenery that show how the urban plan, across established previously legal instruments, like the governmental public politics, to effective the right to development, right of third generation. The director plan how effective tool for local needs - obligation defined by Citizen Statute that contribute for the program linked defined by the urban plan. The state´s intervention on the private sector of citizen, and the restriction on their rights are be justified by the collective´s rights and their quality of life. So, in front the urban scenery has been the plan to make social functions of city, the healthy way of life, which is the sustainable development

Construção e implementação do Balanced Scorecard em uma organização educacional: o caso do Serviço Nacional de Aprendizagem Comercial do Rio Grande do Norte SENAC RN

The changes that have taken place in the organizational environment in recent decades have led to new performance measurement systems being proposed, given the inadequacy of traditional models. The Balanced Scorecard (BSC) emerged as an instrument to translate financial and non-financial assets into real values for all interested parties in the organization, allowing the introduction of strategies to achieve the desired goals. Research shows that most errors committed with the use of this method are related to the implementation process. Thus, the aim of this dissertation is to analyze the process of building and implementing the BSC in an organization. This empirical exploratory study is based on the classic case study method, which enables the researcher to work with a set of evidence, including direct observation, interviews and document analysis. The results show that the use of BSC in the company investigated posed problems during the process of building and implementing the method. These problems were caused mainly by the lack of involvement on the part of upper management and the team s scant knowledge of Balanced Scorecard. One of the gains obtained from adopting the system was the introduction and/or consolidation of a culture of strategic planning and participative management. The continuous implementation phase was highlighted in the monitoring program, created by the organization in an attempt to reverse existing problems, using the BSC as a third generation strategic management system, which led to significant gains, better use of the system and stronger management practices

Estrutura do dossel e acúmulo de forragem dos capins piatã e marandu sob pastejo com ovinos

The objective of this scientific work was to evaluate the tillering and mass production of Brachiaria brizantha Piatã and Marandu grasses with two statures of post-grazing. The experimental lineation was in factorial arrangement (2 pastures x 2 residue stature) with subplots (grazing cycle). The experimental period was from March to October of 2012. The target stature on pre-grazing was 50 cm and on post-grazing 15 and 25 for each cultivar. The following variables were analyzed: tiller population density, forage mass, morphological components, accumulation and accumulation rate. Three grazing cycles were obtained. Marandu grass presented larger forage mass on pre-grazing and lower stem production than piatã grass. No difference was observed between the two cultivars regarding the leaf blade production. There was no difference on forage mass, leaf blade, stem, and dead material production between the two statures of post-grazing. The pastures managed at 25 cm presented accumulation rate compared to those with 15 cm. Concerning the accumulation rate on the two cultivars, piatã and marandu grasses, Marandu grass presented higher amount than the piatã grass, and also presented higher values on the rate of basal tiller appearing on 15 cm stature post-pasture feature. Piatã grass managed at 25 cm developed smaller tiller amount on the second generation and greater tiller amount on the third generation than marandu grass. The greater tiller population density was observed on 25cm post-grazing pastures. There was no statistical difference of density between the two cultivars and between the cycles. Accordingly, it is concluded that piatã and marandu cultivars can be managed with 15cm and 25 cm post-grazing statures

Modelagem do clima de ondas e seus efeitos sobre as feições morfológicas costeiras no litoral setentrional do Rio Grande do Norte

This thesis presents the results of application of SWAN Simulating WAves Nearshore numerical model, OF third generation, which simulates the propagation and dissipation of energy from sea waves, on the north continental shelf at Rio Grande do Norte, to determine the wave climate, calibrate and validate the model, and assess their potential and limitations for the region of interest. After validation of the wave climate, the results were integrated with information from the submarine relief, and plant morphology of beaches and barrier islands systems. On the second phase, the objective was to analyze the evolution of the wave and its interaction with the shallow seabed, from three transverse profiles orientation from N to S, distributed according to the parallel longitudinal, X = 774000-W, 783000-W e 800000-W. Subsequently, it was were extracted the values of directional waves and winds through all the months between november 2010 to november 2012, to analyze the impact of these forces on the movement area, and then understand the behavior of the morphological variations according to temporal year variability. Based on the results of modeling and its integration with correlated data, and planimetric variations of Soledade and Minhoto beach systems and Ponta do Tubarão and Barra do Fernandes barrier islands systems, it was obtained the following conclusions: SWAN could reproduce and determine the wave climate on the north continental shelf at RN, the results show a similar trend for the measurements of temporal variations of significant height (HS, m) and the mean wave period (Tmed, s); however, the results of parametric statistics were low for the estimates of the maximum values in most of the analyzed periods compared data of PT 1 and PT 2 (measurement points), with alternation of significant wave heights, at times overrated with occasional overlap of swell episodes. By analyzing the spatial distribution of the wave climate and its interaction with the underwater compartmentalization, it was concluded that there is interaction of wave propagation with the seafloor, showing change in significant heights whenever it interacts with the seafloor features (beachrocks, symmetric and asymmetric longitudinal dunes, paleochannel, among others) in the regions of outer, middle and inner shelf. And finally, it is concluded that the study of the stability areas allows identifications of the most unstable regions, confirming that the greatest range of variation indicates greater instability and consequent sensitivity to hydrodynamic processes operating in the coastal region, with positive or negative variation, especially at Ponta do Tubarão and Barra do Fernandes barrier islands systems, where they are more susceptible to waves impacts, as evidenced in retreat of the shoreline
