Finding The Optimum Route For Transmission Lines Within Gis

Ozturk, Tunay 01 May 2007 (has links) (PDF)
This study defines the optimum route planning for Electric Transmission Lines by Multicriteria Decision Analysis which is based on Geographic Information Systems (GIS). Determination of the optimum route is performed by using both the spatial and Euclidean distances between two points located on the Earth&rsquo / s surface. The criteria needed to be taken into account to define the route of the Electrical Transmission Lines were evaluated with help of the experts who are doing this business in the available system and for this study the decision about the usage of needed data such as landuse map, landuse capability map, geology map, road map, zone plan and digital elevation models is also made with their knowledge. A Matlab code, which computes the optimum distance between two transformers by using real distance (spatial distance) method and by considering materials mentioned above is written. The results are compared with the ones found from the Euclidian distance, which is the common distance finding method in the available commercial GIS softwares. The spatial resolution effect in finding the spatial distance is also analyzed. The routes obtained by two different distance computation methods are compared with the existing route. The economical expectations in finding the optimum route are also discussed.

Design And Implementation Of Semantically Enriched Web Services In The Healthcare Domain

Altintakan, Umit Lutfu 01 December 2004 (has links) (PDF)
Healthcare Informatics suffers from the lack of information exchange among domain partners. Allowing cooperation among distributed and heterogeneous applications is a major need of current healthcare information systems. Beyond the communication and integration problems, medical information itself is by nature complex, combined with data and knowledge. The increasing number of standards and representation of the same data in different structures using these standards constitute another problem in the domain. Platform and implementation independency makes Web service technology the natural way to solve the interoperability problems in the healthcare domain. Standardizing the access to data through WSDL and SOAP rather than standardizing the electronic health record will help to overcome the integration problems among different standards in medical information systems. However, introducing Web services to the healthcare systems will not suffice to solve the problems in the domain unless the semantics of the services are exploited. This thesis aims to show that by generating web services and classifying these services through their functionalities, it is possible to achieve the interoperability among healthcare institutes, such as hospitals. The designed system is based on Artemis P2P Framework, and the annotation of the system is realized in the same framework.

Automated Biological Data Acquisition And Integration Using Machine Learning Techniques

Carkacioglu, Levent 01 February 2009 (has links) (PDF)
Since the initial genome sequencing projects along with the recent advances on technology, molecular biology and large scale transcriptome analysis result in data accumulation at a large scale. These data have been provided in different platforms and come from different laboratories therefore, there is a need for compilation and comprehensive analysis. In this thesis, we addressed the automatization of biological data acquisition and integration from these non-uniform data using machine learning techniques. We focused on two different mining studies in the scope of this thesis. In the first study, we worked on characterizing expression patterns of housekeeping genes. We described methodologies to compare measures of housekeeping genes with non-housekeeping genes. In the second study, we proposed a novel framework, bi-k-bi clustering, for finding association rules of gene pairs that can easily operate on large scale and multiple heterogeneous data sets. Results in both studies showed consistency and relatedness with the available literature. Furthermore, our results provided some novel insights waiting to be experimented by the biologists.

Availability Management In Configure-to-order Manufacturing Systems

Yontem, Huseyin Erdem 01 December 2009 (has links) (PDF)
AVAILABILITY MANAGEMENT IN CONFIGURE-TO-ORDER MANUFACTURING SYSTEMS Y&ouml / ntem, H&uuml / seyin Erdem M.Sc., Operational Research Supervisor: Asst. Prof. Dr. Sedef Meral December 2009, 98 pages In resource constrained supply chains, where demand is higher than the supply, the decision whether to accept or reject the customer order is a very critical task from resource planning and customer service level perspectives. Since the customers, in today&lsquo / s e-business environment, expect quick responses to their orders, some in-advance work has to be done before the arrival of actual customer orders, especially in configure-to-order (CTO) and make-to-order (MTO) production systems. Available-to-Promise (ATP) is a business function that is becoming the central management system for today&lsquo / s dynamic supply chains whose responsibility is to respond customer orders by considering the trade-off between front-end customer satisfaction and back-end capacity allocation. In this study, we propose an availability management approach that introduces push-based allocation planning by using order segmentation before the arrival of actual customer orders in CTO production environments. Moreover, a two-step order promising framework is introduced in order to increase customer service levels through giving certain or v tentative delivery dates immediately to customer orders before the batch, rule-based actual resource consumption processes. The proposed approach is applied to the real-life processes of an enterprise in order to analyze its applicability and evaluate the benefits that accrue. The results of the experiments prove that, the four-phased availability management approach contribute to both overall profit and customer service levels.

FRAMTIDENS TURISTINFORMATIONSCENTRUM : En kvalitativ studie om hur Sveriges fysiska turistinformationscentrum kan arbeta med digital kommunikation

Rubin, Cajsa January 2024 (has links)
Turistinformationscentrum finns för att tillhandahålla besökare med relevant information om destinationen samt för att förbättra och anpassa vistelsen utefter besökarnas personliga preferenser. I samband med utvecklingen av digital kommunikation har besökarnas tillvägagångssätt att ta del av turistinformation förändrats. Tillgängligheten till turistinformation har fått turismutvecklare att spekulera om det fysiska turistinformationscentrum i framtiden kommer att fortsätta tillhandahålla information och tjänster i sitt nuvarande format. Uppsatsen är en kvalitativ studie med syfte att undersöka hur fysiska turistinformationscentrum påverkas av digital kommunikation i sin dagliga verksamhet. Detta för att bringa förståelse hur turistinformationscentrum kan arbeta i framtiden med digitala kommunikation i sin dagliga verksamhet. För att undersöka hur turistinformationscentrum kan arbeta med digital kommunikation i framtiden genomfördes kvalitativa intervjuer med utvalda intressenter som representerade två olika organisationstyper. Resultatet tyder på att turistinformationscentrumen arbetar olika med digital kommunikation och att det har olika synsätt på hur turistinformationscentrum arbete med digital kommunikation kommer att se ut i framtiden. Flera av respondenterna konstaterar att Artificiell Intelligens (AI) kommer att få en större betydelse i deras sätt att tillhandahålla information till besökarna. För att öka turistinformationscentrums attraktivitet med hjälp av digital kommunikation behöver chatt GPT bli mer kvalitetssäkrad i den information den tillhandahåller. Samverkan mellan turistinformationscentrum och andra turismaktörer behöver också bli bättre för att tillgängliggöra turistinformationscentrum som informationskälla. Det genomgående mönstret för studien är att turistinformationscentrum behöver arbeta med digital kommunikation som kan tillhandahålla personlig och marknadsneutral turistinformation. Tanken är att det ska fungerar som en förlängd arm av deras nuvarande verksamhet. I slutsatsen går det därmed att konstatera att turistinformationscentrumen behöver implementera digital kommunikation för att stärka sin attraktivitet bland framtidens besökare. För att det ska ses som en attraktiv källa av turistinformation behöver det existera i de digitala kanaler som besökarna använder sig av. / A Tourist information center exists to provide visitors with relevant information about the destination as well as to improve and adapt the visit to the visitors personal preferences. In conjunction with the development of digital communication, the visitors approach to accessing tourist information has changed. The availability of tourist information have made tourist developers to begin speculate about the physical tourist information center, if they in the future will keep providing information and services in its current state. This essay is a qualitative study with the purpose of examining how physical tourist information center in the future will be affected by digital communication in their daily operations. This study is to understand how and if tourist information center can still exist in the future with digital communication in its current state. Qualititative interviews where implemented with selected stakeholders to identify what kind of impact digital communication has on tourist information center daily activities. Two different organisations are represented to better understand how tourist information centers can work with digital communications in the future.The result implies that tourist information center are using digital communication differently. They have different points of views about their future work with digital communication. The majority of the respondents point out that Artificial Intelligence (AI) will have a greater purpose in their ways to provide information to the visitors. To increase the attractiveness of tourist information centers with the help of digital communication the AI chat GPT needs to provide more quality assured tourist information. The cooperation between tourist information centers and other tourism companies need to make the tourist information centers more available as a tourist information source. The consistent pattern of this study is that tourist information centers need to work with digital communication that can provide personal and market neutral information and works as an extension of their current business. The conclusion shows that tourist information centers need to implement digital communication to strengthen their attractivity among future visitors. For it to be seen as an attractive source of tourist information centers, it needs to exist in the digital channels that visitors are using. / <p>2024-05-29</p>

Estudo sistêmico da geração de conhecimento no IPEN / Systemic study of knowledge generation at IPEN

MONTEIRO, CARLOS A. 25 August 2016 (has links)
Submitted by Marco Antonio Oliveira da Silva (maosilva@ipen.br) on 2016-08-25T18:15:44Z No. of bitstreams: 0 / Made available in DSpace on 2016-08-25T18:15:44Z (GMT). No. of bitstreams: 0 / Com o escopo de fornecer subsídios para compreender como o processo de colaboração científica ocorre e se desenvolve em uma instituição de pesquisas, particularmente o IPEN, o trabalho utilizou duas abordagens metodológicas. A primeira utilizou a técnica de análise de redes sociais (ARS) para mapear as redes de colaboração científica em P&D do IPEN. Os dados utilizados na ARS foram extraídos da base de dados digitais de publicações técnico-científicas do IPEN, com o auxílio de um programa computacional, e basearam-se em coautoria compreendendo o período de 2001 a 2010. Esses dados foram agrupados em intervalos consecutivos de dois anos gerando cinco redes bienais. Essa primeira abordagem revelou várias características estruturais relacionadas às redes de colaboração, destacando-se os autores mais proeminentes, distribuição dos componentes, densidade, boundary spanners e aspectos relacionados à distância e agrupamento para definir um estado de redes mundo pequeno (small world). A segunda utilizou o método dos mínimos quadrados parciais, uma variante da técnica de modelagem por equações estruturais, para avaliar e testar um modelo conceitual, apoiado em fatores pessoais, sociais, culturais e circunstanciais, para identificar aqueles que melhor explicam a propensão de um autor do IPEN em estabelecer vínculos de colaboração em ambientes de P&D. A partir do modelo consolidado, avaliou-se o quanto ele explica a posição estrutural que um autor ocupa na rede com base em indicadores de ARS. Nesta segunda parte, os dados foram coletados por meio de uma pesquisa de levantamento com a utilização de um questionário. Os resultados mostraram que o modelo explica aproximadamente 41% da propensão de um autor do IPEN em colaborar com outros autores e em relação à posição estrutural de um autor na rede o poder de explicação variou entre 3% e 3,6%. Outros resultados mostraram que a colaboração entre autores do IPEN tem uma correlação positiva com intensidade moderada com a produtividade, da mesma forma que, os autores mais centrais na rede tendem a ampliar a sua visibilidade. Por fim, vários outros indicadores estatísticos bibliométricos referentes à rede de colaboração em P&D do IPEN foram determinados e revelados, como, a média de autores por publicação, média de publicações por autores do IPEN, total de publicações, total de autores e não autores do IPEN, entre outros. Com isso, esse trabalho fornece uma contribuição teórica e empírica aos estudos relacionados à colaboração científica e ao processo de transferência e preservação de conhecimento, assim como, vários subsídios que contribuem para o contexto de tomada de decisão em ambientes de P&D. / Tese (Doutorado em Tecnologia Nuclear) / IPEN/T / Instituto de Pesquisas Energeticas e Nucleares - IPEN-CNEN/SP

Foi utilizado banco organizado com esta finalidade a partir dos eventos toxicológicos registrados pelos CEATOX no Estado de São Paulo. Realizou-se dois estudos epidemiológicos descritivos de série de casos: um para o período de 1991 a 2000, no qual observou-se a distribuição em relação às características gerais dos eventos, dos pacientes, dos agentes tóxicos e das circunstâncias em que ocorreram, e outro em 1998, no qual observou-se a distribuição dos eventos toxicológicos relacionados a medicamentos. Encontrou-se no primeiro 128.769 eventos toxicológicos em humanos, originados em sua maioria de ligações telefônicas (68,65%), de serviços de saúde hospitalares (51%); 60,8% dos atendimentos presenciais, foram oriundos de enfermarias e, 33,3%, de UTI. Predominaram as exposições agudas (84,5%), por via oral (68%), oriundas de área urbana (87,8%). O principal local de exposição foi a residência (74%). Predominou para o sexo masculino (52%), com maior concentração até os 10 anos (43%), sobretudo aos 2 e 3 anos de idade. Os agentes tóxicos predominantes foram os: medicamentos (38,6%), agrotóxicos (17,9%) e produtos de uso domiciliar (15,4%). As principais circunstâncias: acidentais (47,0%), tentativas de suicídio (19,8%) e ocupacionais (11,7%). Os medicamentos ocuparam o 1º lugar entre todos os tipos de agentes tóxicos registrados, e foram predominantemente registrados por telefone (78,5%), a partir de hospitais (86,6%); originados em exposições agudas, por via oral (90,2%), em residências (85,7%) de área urbana (95%). Predominou para o sexo feminino (59%) e nos primeiros 10 anos de vida (49,4%), sobretudo aos 2 e 3 anos. Preponderaram os grupos terapêuticos: psiquiatria, analgesia/anestesia e respiratório. Preponderaram os princípios ativos: fenobarbital, diazepam, haloperidol, carbamazepina e bromazepam, e as circunstâncias: acidentais (38,8%) e tentativas de suicídio (36,5%). Foram analisados documentos marcos da política internacional, nacional, e estadual e os aspectos operacionais da toxicovigilância no SUS relacionados à: informação, assistência, vigilância à saúde, constituição de equipes e integração de áreas. Diagnosticaram-se os principais sistemas de informação que registram agravos com o objetivo de verificar o estado da arte em relação às necessidades da toxicovigilância, para o qual estabeleceram-se critérios. Considerou-se estratégica a construção de sistema específico, propôs-se instrumentos e aspectos operacionais. Propôs-se o modelo no marco da vigilância da saúde, a inclusão da exposição e do evento toxicológico como objeto do registro de informações para a toxicovigilância e que as análises e ações consideram causa e contexto, atuando de modo integrado, articulado, programático, com parcerias intersetoriais, promovendo ações preventivas, de promoção da saúde e de precaução / Abstract: The study to make known the toxicological surveillance in the Brazil, with accentuation in the State of São Paulo, as well as toxicological surveillance according to the National Health System guidelines and suggest and model. To assess the epidemiological characteristics of related toxic events in the Toxicology Centers in the State of São Paulo, Brazil, in period 1991 and 2000. A descriptive epidemiological case series study was conducted, using the category related toxic event, and registered cases were analyzed. The variables studied comprised the characteristics of the events and the affected patients, toxic agents and the circumstances involved. In the study 97% (128.769) the related toxic event concerning to human cases, related toxic events were mostly reported by phone (68.65%) and hospitals (51%); they were originated from acute exposure (84,5%), oral (68%) at home (74%) and place to work (13%) in the urban area (87.8%). Most people affected were males (59%) in their first decade of life (43%), mainly between two and three years of age. Drugs ranked first among all toxic agents registered in the Centers (38.6%) and pesticides (17.9%) and the products to use in home (15.4%). The main circumstances were accidental ingestion (47%) and suicidal attempts (19.8%) and the occupactional (11.7%). Another descriptive epidemiological case series study was conducted. Using the category "drug-related toxic event", 6,673 registered cases were analyzed in the Toxicology Centers in the State of São Paulo throughout 1998. The variables studied comprised the characteristics of the events and the affected patients, toxic agents and the circumstances involved. The analysis of toxic agents took into consideration three levels of disaggregation: therapeutical groups, active ingredients and commercial brand names. Drugs ranked first among all toxic agents registered in the Centers. Drug-related toxic events were mostly reported by phone (78.5%) and hospitals (86.6%); they were originated from acute oral exposure (90.2%) at home (85.7%) in the urban area (95%). Most people affected were females (59%) in their first decade of life (49.4%), mainly between two and three years of age. The most common active ingredients found were: phenobarbital, diazepam, haloperidol, carbamazepine and bromazepam. The main circumstances were accidental ingestion (38.8%) and suicidal attempts (36.5%) and among the related active ingredients, the most prevailing therapeutical group were psychiatric, analgesic/anesthetic and respiratory.
