An Analysis of the Telecommunications Business in China by Linear Regression

In this paper, we study the influence of the National Telecom Business Volume by the data in 2008 that have been published in China Statistical Yearbook of Statistics. We illustrate the procedure of modeling “National Telecom Business Volume” on the following eight variables, GDP, Consumption Levels, Retail Sales of Social Consumer Goods Total Renovation Investment, the Local Telephone Exchange Capacity, Mobile Telephone Exchange Capacity, Mobile Phone End Users, and the Local Telephone End Users. The testing of heteroscedasticity and multicollinearity for model evaluation is included. We also consider AIC and BIC criterion to select independent variables, and conclude the result of the factors which are the optimal regression model for the amount of telecommunications business and the relation between independent variables and dependent variable. Based on the final results, we propose several recommendations about how to improve telecommunication services and promote the economic development.

Solcellsdrivet FTX-system för miljonprogramshus : Tjärna Ängar, Borlänge

Projektet omfattade undersökning och framtagande av ett solcellssystem med förmåga att försörja ett FTX-system i ett flerbostadshus från miljonprogrammet med el. För att kunna bedöma storlek och utformning av komponenter har information tagits genom: Informationssökning via databaser, kurslitteratur och intervjuer Simuleringar av solceller i datorprogrammet PVSYST Modulering av ventilationskanaler i datorprogrammet MagiCAD Syftet var främst att undersöka om det gick att få fram ett teoretiskt fungerande system med avseende på både solceller och ventilation. Beroende på vad resultatet blev skulle även ekonomin i projektet undersökas. Undersökningen visade att det teoretiskt ska gå att installera solceller för elframställning som klarar av att täcka FTX-systemets elbehov på årsbasis. Solcellerna bedöms även producera tillräckligt med el för viss övrig elkrävande utrustning under stora delar av året. Det visade sig även att det skulle gå att få solcellerna ekonomiskt lönsamma om en kalkyltid på 14 år används. Metoden som använts för dessa resultat är noga beskriven och är med små förändringar tillämpbar för ett stort antal byggnader i det svenska byggnadsbeståndet. En viktig slutsats är att om fastighetsägarna kan se 15 år fram i tiden för en investering i solenergi, skulle det innebära inte bara miljömässiga utan även ekonomiska vinster. Det finns redan idag kunnande, teknik och produkter för att utvinna en stor del av fastigheternas elbehov genom solens energi.

Paketering av energisparåtgärder i småhus

Ska energimålen med halvering av energianvändningen kunna nås i länet måste småhusägare och ägare av mindre flerbostadshus övertygas om nyttan och möjligheter med att energieffektivisera i egna byggnader. Genom att använda en metod för paketering av energisparåtgärder kan byggnader energirenoveras på ett effektivt sätt och energianvändningen kan på så sätt minimeras. BELOK Totalprojekt är en metod för energieffektivisering i kommersiella byggnader genom renovering med åtgärdspaket. Metoden har även använts för flerbostadshus och uppgiften i den här rapporten är att undersöka ifall samma metod kan vara lämplig att använda även för småhus. Resultaten visar att metoden mycket väl kan användas även för småhus, men att vissa anpassningar är nödvändiga för att småhusägare ska kunna relatera till resultatet. Vid renovering i småhus kan många olika aktörer vara inblandade beroende på hur småhusägaren väljer att utföra en renovering. Om småhusägaren själv gör huvuddelen av arbetet är det lämpligt att Energikalkylen eller motsvarande kan användas för att göra en förenklad energianalys av byggnaden för att sedan föra över data till BELOK Totalverktyg, där det ekonomiska utfallet för renoveringspaket illustreras. Uppföljningen efter slutförd renovering är något som till exempel energibolag skulle kunna erbjuda tjänster för. Om småhusägaren väljer att anlita en energikonsult för den initiala analysen av byggnaden kan BELOK Totalprojekt användas mer i sin helhet men detta innebär förstås en högre kostnad för småhusägaren. För att öppna upp för fler möjligheter för småhusägare att totalrenovera är det viktigt att även involvera banksektorn för att diskutera ett upplägg för lån till energieffektivisering. Här kan även styrmedel av karaktären statliga lånegarantier eller ROT-avdrag för energieffektivisering vara aktuella att ta upp till diskussion. Slutligen är kommunikation med småhusägarna väldigt viktig och här är aktörer som redan idag har kontakt med småhusägare centrala. Två sådana aktörer är energibolag samt Villaägarnas Riksförbund.

Passive solar options for reducing heating demand and maintain indoor climate in a multifamily house in Sweden

This research was carried out by studying possible renovation of a two-storey detached multifamily building by using passive solar design options in a cold climate in Borlänge, Sweden where the heating Degree Days are 4451 (base 20°C). Borlänge`s housing company, Tunabyggen, plans to renovate the project house located inthe multicultural district, Jakobsgårdarna. The goal of the thesis was to suggest a redesign of the current building, decrease the heating energy use, by applying passive solar design and control strategies, in a most reasonable way. In addition ensure a better thermal comfort for the tenants in the dwellings. Literatures have been studied, from which can be inferred that passive design should be abasic design consideration for all housing constructions, because it has advantages to ensure thermal comfort, and reduce the energy use. In addition further savings can be achieved applying different types of control strategies, from which the house will be more personalized, and better adapted to the user’s needs.The proposed method is based on simulations by using TRNSYS software. First a proper building model was set up, which represents the current state of the project building. Then the thermal insulation and the windows were upgraded, based on today's building regulations. The developments of the passive solar options were accomplished in two steps. First of all the relevant basic passive design elements were considered, then those advantages were compared to the advantages of applying new conventional thermostat, and shading control strategies.The results show that there is significant potential with the different types of passive solar design; their usage depends primarily on the location of the site as well as the orientation of the project building. Applying the control strategies, such as thermostat, and shading control, along the thermal insulation upgrade, may lead to significant energy savings (around 40 %), by comparison to the reference building without any upgrade.

Paleoenvironmental analysis of a late-holocene subfossil Coleopteran fauna from Starks, Maine

The Sandy River in central Maine Is flanked along much of its length by low terraces. Approximately 100 kg of sediment from one terrace in Starks, Somerset County, Maine was wet-sieved in the field. Over 1100 subfossil Coleoptera were recovered representing 53 individual species of a total of 99 taxa. Wood associated with the fauna is 2000 +/-80 14C Yr in age (1-16,038). The fauna is dominated by species characteristic of habitats apparent in modern central Maine. The subfossil assemblage is indicative of a wide vartety of environments including open ground (e.g., Harpalus pensylvanicus), dense forest (e.g., pterostichus honestus), aquatic environments (e.g., Gyrinus, Helophorus), riparian environments with sand and gravel substrates (e.g., Bembidion inaequale, Schizogenius lineolatus), and moist, organic-rich terrestrial environments (e.g., Micropeplus sculptus). The ecological requirements for each taxon permit an environmental reconstruction suggesting an area vegetationally, climatically, and ecologically similar to that of the Sandy River today. The lowest terraces apparently represent the modern-day floodplain of the Sandy River. An average sedimentation rate of l.00 to 1.04 mm per year has been inferred based on radiocarbon dates here and elsewhere on the Sandy River. The Coleopteran fauna suggests that sand and gravel were distinctly abundant, and that the aggradation of point bars, as seen today, contributed to the flood history. Lateral bank erosion of the modern Sandy River accelerated after the State of Maine mandated cessation of bar removal in 1975: flood severity has dramatically increased since that time. Implications suggest that mining of the bars may be necessary to minimize future flooding problems.

O posicionamento dos tribunais perante os contratos de distribuição (1980-1999)

Esta pesquisa tem por objeto a análise sistemática da jurisprudência brasileira sobre os contratos de distribuição entre os anos de 1.980 e 2.000, procurando identificar qual a posição dos nossos Tribunais face a esses contratos. Nessa linha, constatou-se que os casos (acórdãos) abrem-se em cinco grandes blocos, quais sejam: (1) atribuição/divisão territorial; (2) questões possessórias; (3) renovatória de locação; (4) rescisão dos contratos de distribuição. Este grupo divide-se (i) naqueles contratos sujeitos à Lei Ferrari, (ii) naqueles referentes ao setor de combustíveis e derivados e (iii) naqueles não subsumíveis a tal diploma; (5) questões processuais relevantes, dividido em (i) litisconsórcio necessário e (ii) título executivo extrajudicial. Além disso, por se tratar de uma avenca atípica na maioria dos casos, a pesquisa procurou extrair de cada um dos casos qual o conceito de contrato de distribuição adotado.

Manutenção produtiva total: o caso da Eletronorte

The continuous search of the increase of the productivity has been facilitating the growing diffusion of modern and advanced technologies, that open new ways for the renovation of the industrial productive process, as well as, to the appearance of modern administration systems that establish ways in direction to the democratization of the social relationships in the organizations. Accompanying that tendency and, motivated by the competitive characteristic of the market of electric energy, Eletronorte, adopted the Total Productive Maintenance - TPM, of japanese origin, as the system of administration of its productive process. This dissertation has as objective, to analyze the methodological content of the Total Productive Maintenance, showing its significance and its reach in the Regional of Transmission of Mato Grosso, adopting the post fordism, as comparison paradigm. The whole study and analysis had as focus the offices of the company and the Substation of Coxipó, placed in the city of Cuiabá, as well as the Substations of Rondonópolis and Sinop, placed in cities with the same name. The offices and the substations are geographically located in the state of Mato Grosso, and under the responsibility of the Regional of Transmission of Mato Grosso, of the Centrais Elétricas do Norte do Brasil SA - Eletronorte. The work method was of qualitative orientation and of case study, through a research of applied nature. The research was accomplished with explanatory and exploratory objectives. They were used as instruments of collection of data the analysis of documents, interviews, and application of questionnaires. The data collected through documents and of the application of questionnaires they were compiled and analyzed. The results of the interviews had for objective to confirm the consistency of the collected data. The obtained results demonstrate increases of productivity of the order of 40%, and reduction of the costs of up to 29%. The study still demonstrated, that TPM provoked significant impacts in the practices you work, denoting the presence of an action managerial dialógica. It was still characterized that the transference of TPM will depend in that context the administration system will be applied, because if this is here different from it studied, there won't be transference warranties.

O modelo gerencial do controle interno governamental: as melhores práticas de Pernambuco

Diante da importância do tema relacionado à atividade de controle interno governamental, no cenário nacional e internacional, tendo em vista o aumento da corrupção e a ineficiência administrativa no alcance dos resultados voltados para os cidadãos e ainda, da escassez de pesquisas exploratórias acerca da atividade de controle com enfoque na efetividade em busca da melhoria do gasto público, este estudo procurou identificar práticas da gestão do controle interno governamental que repercutem efetivamente na melhoria da qualidade do gasto público. Para isso procurou conceituar a qualidade do gasto relacionada à atuação do controle interno governamental e avaliar o modelo gerencial de controle interno adotado pelo Estado de Pernambuco, diagnosticando as práticas que estão diretamente relacionadas à melhoria da qualidade na aplicação do recurso público. A escolha do órgão de controle interno governamental do Estado de Pernambuco para o objeto deste estudo deve-se ao fato deste órgão ter sido palco de grandes mudanças na sua gestão com vistas à renovação e adaptação à nova demanda da sociedade que clama pela transparência e qualidade na aplicação do recurso público. Dos resultados apresentados foi possível identificar práticas decorrentes da ação do órgão de controle interno na gestão pública que indicaram um ganho financeiro para o Estado, ficando assim o recurso disponível para a ampliação de benefícios destinados à sociedade. Salientou-se, ainda, o custo da estrutura organizacional do órgão de controle, fato que apontou para um resultado econômico positivo decorrente das ações do órgão de controle interno. O estudo concluiu pela existência de alinhamento do órgão de controle de Pernambuco com os princípios mais modernos de gestão a partir do enfoque no resultado das ações. No entanto, apesar de estar na direção certa, ficou evidente a necessidade de grandes avanços com o fim de potencializar as ações de controle na gestão pública estadual.

A modernização do ginásio e a manutenção da ordem

processo de modernização do ginásio secundário brasileiro, que culminou com a Reforma do Ensino do primeiro grau, nos anos 70 e, portanto, com a estruturação de uma nova escola· fundarrental. A maioria das propostas para a criação de um novo ginã 510, nos anos 50 e 60 I procurava atende~ às exigências do modelo político e econômico da época. No período 61-64, fase crítica do modelo desenvolvimentista, surgiram projetos de educação secundária, como os Ginásios da Comunidade e os Giná 5105 Vocacionais, propondo urna prá~ica pedagógica, voltada para a conscientização do homem como ser histórico e produtivo e, conseqüentemente, orientada para a transformação da sociedade. A política educacional, após 1964, rechaçou as propostas de uma e'ducação secundária conscientizadora e lançou os Ginásios Poli valentes corno estratégia para a reFormulação do ensino de primeiro grau em âmbito nacional. Concluiu-se que os projetos de renovaçao do ensino secundário surgiram em decorrência das contradições do ItXldelo desenvolvimentista. Enquanto os Ginásios Poli valentes apre - sentavam uma proposta pedagógica compatível com a manutenção do capitalismo periférico, os projetos de criação dos Ginásios da Comw1idade e dos Ginásios Vocacionais constituiram resposta diferente da política de dominação cultural.

Da cozinha ao terreiro em Mutamba da Caieira (RN) : cotidiano, espaço doméstico e sociabilidade

In this work we thought about the social use of the domestic space and, specifically, the space destined to the preparation of food. The kitchen is a creative space of social relationships. There the families exchange daily interaction with the neighbors, in a collective of the space reserved to the making of food. Our empiric research was in the Mutamba da Caieira community, located in the county of Assu (RN). The data was collected through the etnographic method aided by the photographic resources. In the discussion, we delimitated at the house three types of kitchens: one reserved to the family, another kitchen in the terrace and yet another kitchen in the yard. They are kitchens that link amongst themselves with activities and differentiated temporalities. In the daily social exchange, the kitchen imposes itself as a social space through the conditions that it offers for the production of the foods, the circulation of domestic objects, the communication of knowledge around the cookery, operating a group of symbolic and ritual actions combined with appropriate techniques for the transformation of the foods. The study reveals that the domestic chores accomplished amon relatives and friends form webs of intracommunitary relationships in the use of the three kitchens, and that the social network is updated in a singular moment that usually happens in the community, the Game of Pacará

Análise de métodos para aplicação de ventilação natural em projetos de edificações em Natal-RN

Natural ventilation is an efficient bioclimatic strategy, one that provides thermal comfort, healthful and cooling to the edification. However, the disregard for quality environment, the uncertainties involved in the phenomenon and the popularization of artificial climate systems are held as an excuse for those who neglect the benefits of passive cooling. The unfamiliarity with the concept may be lessened if ventilation is observed in every step of the project, especially in the initial phase in which decisions bear a great impact in the construction process. The tools available in order to quantify the impact of projected decisions consist basically of the renovation rate calculations or computer simulations of fluids, commonly dubbed CFD, which stands for Computational Fluid Dynamics , both somewhat apart from the project s execution and unable to adapt for use in parametric studies. Thus, we chose to verify, through computer simulation, the representativeness of the results with a method of simplified air reconditioning rate calculation, as well as making it more compatible with the questions relevant to the first phases of the project s process. The case object consists of a model resulting from the recommendations of the Código de Obras de Natal/ RN, customized according to the NBR 15220. The study has shown the complexity in aggregating a CFD tool to the process and the need for a method capable of generating data at the compatible rate to the flow of ideas and are discarded during the project s development. At the end of our study, we discuss the necessary concessions for the realization of simulations, the applicability and the limitations of both the tools used and the method adopted, as well as the representativeness of the results obtained

Os filhos evangélicos do novo caldeirão do diabo: a conversão religiosa na penitenciária de alcaçuz

The theme of the research is inserted at a field of intersection between the Sociology of Religion and Sociology of Violence, having as the general objective study the sociological meaning of the conversion of prisoners that lives at the biggest prison (Prison of Alcaçuz) of Rio Grande do Norte to the evangelical churches. The research is justified, because Brazil shelter the fourth greater arrested population arrested of the world, with projections indicating that it can turn the greatest in 2034. Besides, this study about religious conversion of prisoners to the Social Sciences is too important, because is a theme little developed in Brazil and deserves attention, one time that as the arrested people as the evangelicals are in expansion in our country. Starting from the precedent observations, we guide ourselves by the following problematic of research: the religious practice in Alcaçuz presents a mere instrumental perspective, where the actions of prisoners converted was on purpose oriented to conquest material or symbolic privileges; or purely religious, where seek a moral renovation? To develop the work, the scientific methodology adopted was exploratory and explanatory, using the Goffman´s theory about total institutions and presentation of self, and Blumer´s doctrine relating to Symbolic Interacionism and the Story life method, besides considerations about evangelical religion. Having this theoretical basis, was accomplished the Field research, when were made interviews and applied questionnaires to 11 Jailer Agents, 31 prisoners, Director and Vice-Dictor (in November, 2011), the coordinator of social projects of the prison and the coordinator of evangelization at the prisons in Rio Grande do Norte. As results, it was seeing in Alcaçuz that the prisoners can be separated in two groups: the one of Pavilions and other one of the Medical Section. The Pavilions are branded for managerial and structural problems, where are found idle prisoners in collective cells and with a historical of escaping attempts, mutinies and murders. The Medical Section has some individual cells or destined for two people, besides few collective also, and the prisoners work and have a more disciplined behavior, there isn t escapes or rebellions and that, for these reasons end for have more confidence from the Administration. About the presence of evangelical prisoners, most are at Medical Section, where exist a specific place to the cults (what doesn t at Pavilions). At the end, the conclusion is that the prisoner that says himself evangelical in Alcaçuz, although can be seeing with distrust about your real conversion, he gets win a trust vote and until the opposite being demonstrated in other words, that he is not hiding himself behind the bible to divert the vigilance of Direction and practice disciplinary faults without make any suspicions, is treated with more respect and has more opportunities live at Medical Section; have work, that most of times is paid and guarantee the homologation of your payment of penalty with work, besides other benefits, diminishing his time in jail

O corredor cultural: espaço de materialização da exclusão social em Mossoró-RN

In contemporary society, social exclusion is an actual and pertinent theme, because it presents itself as a challenge to management and planning of the public policies. In this perspective, the thesis entitled "The Cultural Corridor: space materialization of social exclusion in Mossoró-RN" is a moment of apprehension and analysis of the local reality from the urban policy implementation that emphasized an enterprising model, which has, as the concrete space to urban renovation manifestation, the cultural complex called cultural corridor. Because of the investigation and the directional hypothesis, it is possible to say that the urban development policy implemented in Mossoró, starting from the 1990 decade, based in the model of modernizing/enterprising management, has been causing an intensification of a society parcel exclusion from the city public space, since this public policy didn't prioritized job market increasing, as well as population incomes improving, poverty and social inequality reduction, at the same proportions it promoted geographic space reorganization with directional actions to build the "spectacle city"

De Escola Normal de Natal a Instituto de Educação de Presidente a Kennedy (1950−1965): configurações, limites e possibilidades da formação docente

La recherche ci-présentée consiste dans une narrative historique problematisée par rapport à la trajectoire de l École Normale de Natal. Dans ce parcours, nous distingons sa transformation en Institut d Éducation Président Kennedy, en envisageant la période de 1950 jusqu à 1965. L investigation a été procédée ayant pour base les principes de l histoire des institutions éducatives, on a pris deux catégories d analyse historique : la culture scolaire, utile à la compréhension des pratiques éducatives developpées dans l institution d enseignement ; et celle de genre, l École Normale de Natal/Institut d Éducation pour avoir été fréquentés principalement par des femmes qui voulaient travailler dans l enseignement primaire ; alors, une place de genre. Dans cette perspective, nous estimons sa multiplicité d acteurs et de leurs pratiques dans l institution. Nous mettons en évidence sa création et les cycles de son développement (matérialisés dans les plusieurs configurations), en les reliant aux faits locaux et nationaux. Nous distingons les conflits tout le long des années en ce qui concerne l inexistence de l espace physique pour le fonctionnement adéquat de l école, et les changements du savoir apporté moyennant la renovation du programme d enseigement et de la pratique pédagogique. Ainsi, de la tradictionnelle École Normale de Natal à l Institut d Éducation Président Kennedy, cette institution éducative a gardé, dans son identité, le caracter de modèle et d innovation, quand elle a pu assimiler les changements didactico- pédagogique qui avaient eu lieu dans le scénario national se transformant en un centre de référence pour la formation des professeurs, particulièrement des femmes, en différentes époques dans l enseignement potiguar. L École Normale de Natal s est constituée surtout en un établissement pour la conquête, un chemin pour l élargissement de l univers du rôle de ces femmes qui se déplacent de la sphère de l enseignement privé pour accéder au domaine de l enseignement publique, acquérant ainsi un travail rémunéré

Metodologia estatística na solução do problema do caixeiro viajante e na avaliação de algoritmos : um estudo aplicado à transgenética computacional

The problems of combinatory optimization have involved a large number of researchers in search of approximative solutions for them, since it is generally accepted that they are unsolvable in polynomial time. Initially, these solutions were focused on heuristics. Currently, metaheuristics are used more for this task, especially those based on evolutionary algorithms. The two main contributions of this work are: the creation of what is called an -Operon- heuristic, for the construction of the information chains necessary for the implementation of transgenetic (evolutionary) algorithms, mainly using statistical methodology - the Cluster Analysis and the Principal Component Analysis; and the utilization of statistical analyses that are adequate for the evaluation of the performance of the algorithms that are developed to solve these problems. The aim of the Operon is to construct good quality dynamic information chains to promote an -intelligent- search in the space of solutions. The Traveling Salesman Problem (TSP) is intended for applications based on a transgenetic algorithmic known as ProtoG. A strategy is also proposed for the renovation of part of the chromosome population indicated by adopting a minimum limit in the coefficient of variation of the adequation function of the individuals, with calculations based on the population. Statistical methodology is used for the evaluation of the performance of four algorithms, as follows: the proposed ProtoG, two memetic algorithms and a Simulated Annealing algorithm. Three performance analyses of these algorithms are proposed. The first is accomplished through the Logistic Regression, based on the probability of finding an optimal solution for a TSP instance by the algorithm being tested. The second is accomplished through Survival Analysis, based on a probability of the time observed for its execution until an optimal solution is achieved. The third is accomplished by means of a non-parametric Analysis of Variance, considering the Percent Error of the Solution (PES) obtained by the percentage in which the solution found exceeds the best solution available in the literature. Six experiments have been conducted applied to sixty-one instances of Euclidean TSP with sizes of up to 1,655 cities. The first two experiments deal with the adjustments of four parameters used in the ProtoG algorithm in an attempt to improve its performance. The last four have been undertaken to evaluate the performance of the ProtoG in comparison to the three algorithms adopted. For these sixty-one instances, it has been concluded on the grounds of statistical tests that there is evidence that the ProtoG performs better than these three algorithms in fifty instances. In addition, for the thirty-six instances considered in the last three trials in which the performance of the algorithms was evaluated through PES, it was observed that the PES average obtained with the ProtoG was less than 1% in almost half of these instances, having reached the greatest average for one instance of 1,173 cities, with an PES average equal to 3.52%. Therefore, the ProtoG can be considered a competitive algorithm for solving the TSP, since it is not rare in the literature find PESs averages greater than 10% to be reported for instances of this size.
