In his account of the intellectual cognition of singulars, Aquinas claims that the intellect cognizes singulars by way of mental images. Some recent commentators have claimed that Aquinas' appeal to mental images is inadequate to account for the intellectual cognition of singulars because mental images considered in terms of their qualitative character alone have content that is general and are, therefore, insufficient to determine reference to a singular. That is, if Aquinas takes mental images to refer to singulars because those singulars perfectly resemble the mental images, then his account is deficient. In my paper, I argue that the critical interpretation above is predicated on a misunderstanding of Aquinas regarding the intentionality of images. I investigate Aquinas' account of the intentionality of images in order to show that Aquinas understands the reference of mental images to be determined not by their qualitative character alone but also by the causal relation that obtains between the cognizer and a singular. / Master of Arts

The aim is to determine the effect of reference standard related bias on estimates of plain radiograph reading performance using studies conducted in clinical practice. Data were extracted on study eligibility, clinical and reference standard characteristics and reading performance. The choice of reference standards and the prevalence of bias are presented descriptively. Associations between bias and reading performance are estimated using a regression model that produces relative diagnostic odds ratios (RDOR) with 95% confidence intervals (CIs). Three of the 20 eligible studies addressed all five reference standard related biases; 15 studies addressed three or more. When the reference standard report is influenced by knowledge of an observer's opinion this is associated with a significant overestimation in reading performance (RDOR, 3.7; 95% CI, 1.6 to 8.3; p¿=¿0.01). There is limited evidence that reading performance is inflated when the observer is aware of the reference standard report before commenting on the radiograph (RDOR, 1.7; 95% CI, 0.6 to 5.1) and deflated when a less valid reference standard is used (RDOR, 0.5; 95% CI, 0.1 to 2.5). There is no evidence that reading performance is affected by application of the reference standard depending on an observer's opinion and using different reference standards in the same study. In conclusion we found variation in the choice and application of reference standards in studies of plain radiograph reading performance, but only when reference standards report in the knowledge of an observer's opinion does this contribute to a significant overestimation in reading performance.

Tailsitter UAVs (Unmanned Aerial Vehicles) are a type of VTOL (Vertical Take off and Landing) aircraft that combines the agility of a quadrotor drone with the endurance and speed of a fixed-wing aircraft. For this reason, they have become popular in a wide range of applications from tactical surveillance to parcel delivery. This thesis details a clean sheet design process for a tailsitter UAV that includes the dynamic modeling, control design, simulation, vehicle design, vehicle prototype fabrication, and testing of a tailsitter UAV. The goal of this process was to design a robust controller that is able to handle uncertainties in the system's parameters and external disturbances and subsequently can control the vehicle through the transition between vertical and horizontal flight regimes. It is evident in the literature that most researchers choose to model and control tailsitter UAVs using separate methods for the vertical and horizontal flight regimes and combine them into one control architecture. The novelty of this thesis is the use of a single dynamical model for all flight regimes and the robust control technique used. The control algorithm used for this vehicle is a MRAC (Model Reference Adaptive Control) law, which relies on reference models and gains that adapt according to the vehicle's response in all flight regimes. To validate this controller, numerical simulations in Matlab and flight tests were conducted. The combination of these validation methods confirms our adaptive controller's ability to control the transition between the vertical and horizontal flight regimes when faced with both parametric uncertainties and external disturbances. / Master of Science / Unmanned aircrafts have been a topic of constant research and development recently due to their wide range of applications and their ability to fly without directly involving pilots. More specifically, VTOL UAVs have the advantage of being able to take off without a runway while retaining the efficiency of a classical aircraft. A tailsitter UAV behaves as a traditional quadrotor drone when in its vertical configuration and can rotate to a horizontal configuration, where it takes advantage of its wings to fly as a conventional aircraft. Modeling the dynamics of the tailsitter UAV and designing an autopilot controller is the main focus of this thesis. An adaptive controller was chosen for the tailsitter UAV due to its ability to modify the gains of the system based on the behavior of the vehicle to adapt to the unknown vehicle properties. This controller was validated using both computer simulations and actual flight tests. It was found that the adaptive controller was able to successfully control the transition between the vertical and horizontal flight regimes despite the uncertainties in the parameters of the vehicle.

International Telemetering Conference Proceedings / October 29-November 02, 1990 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper describes the technical principle that signals conversion, data-processing and data storage are directly carried out without filling up with the reference pulse for PPM and PPK (pulse position keying). By means of analysis for typical frame structure of PPM/PPK signals, a variety of math models of signal time relationship of the system were found, and based on this, a engineering way and a principle block diagram for signals conversion, data processing and data storage were given out.

We present a distributed garbage collection algorithm for Java distributed objects using the object model provided by the Java Support for Distributed Objects (JSDA) object model and using weak references in Java. The algorithm can also be used for any other Java based distributed object models that use the stub-skeleton paradigm. Furthermore, the solution could also be applied to any language that supports weak references as a mean of interaction with the local garbage collector. We also give a formal definition and a proof of correctness for the proposed algorithm.

In this context, looms as a major strengthening of the system of Primary Health Care, which has demonstrated the essence of the effectiveness of care, enabling a holistic approach to people. In this sense, it is necessary an efficient monitoring of the patient by means of the reference and counter reference. Objective: To analyze strategies to implement the Electronic System Reference and counter reference in the Family Health Unit (FHU) in the city of Anápolis, Goiás. Material and Methods: The study was a prospective, nonrandomized intervention, developed in two of the three FHU research. The experimental and control groups were chosen on the basis of convenience. Visits were made by the researcher to the health units, explanations about the research and requests for assistance to the professionals. The interventions were performed by means of encouragement and guidance to professionals and patients. It was used among the instruments: Sheets Guidelines and Flow and Letter Search. In one of FHU Intervention was made available the Electronic Reference and counter reference. We carried out the monitoring, the FHU study and the National Regulatory System (SISREG), the flow of patients referred to specialists in the period from 1 August 2012 to 1 December 2012. Visits to medical specialists were made who treated the patients referred and also active search for patients who have not returned or returned without the counter reference - FHU source. It was evaluated the number of references, counter reference and reasons for non-return of patients and counter reference to the three FHU from study. Data were analyzed using STATA version 11.0. Results: Of the total of 6,218 medical consultations, it was performed 532 accompaniments to specialists physicians and 492 patients accompaniments. The referral rate was 8.56 %. They were requested and scheduled more appointments in FHU intervention. Of referrals made, 54.27 % were scheduled consultations. Of these, 11.61 % patients returned to FHU source routing. The time of the patient's return home to FHU, after issuing the referral reference ranged from 6 to 110 days. The patients return home at FHU occurred only in Intervention, and of these patients, almost half returned to the counter reference manually. Conclusions: The study demonstrated rate of referrals in accordance with international standards; difficulties of access to specialized consultations, low number of patients returns to FHU source routing, as well , that guidance and encouragement to professionals and patients positively affect the patients return to the FHU and counter reference source. It was believed to be feasible to implement the referral system and counter reference electronically, allowing better communication between professionals safely and quickly and greater integration between services. / Introdução: Nos últimos tempos, o Sistema Único de Saúde brasileiro vem passando por várias inovações na gestão, na organização, no financiamento e em seus serviços. Nesse contexto, avulta como importante o fortalecimento do sistema de Atenção Primária à Saúde, que tem demonstrado a essência da efetividade do cuidado, viabilizando uma abordagem integral às pessoas. Nesse sentido, é necessário um eficiente acompanhamento do paciente, por meio dos instrumentos de referência e contrarreferência. Objetivo: Analisar estratégias para implantação de Sistema Eletrônico na Referência e Contrarreferência em Unidade de Saúde da Família (USF) no município de Anápolis-Goiás. Material e Métodos: O estudo realizado foi prospectivo, de intervenção não randomizada, desenvolvido em duas das três USF da pesquisa. Os grupos experimentais e de controle foram escolhidos com base em critérios de conveniência. Foram feitas visitas pela pesquisadora às unidades de saúde, explanações sobre a pesquisa e solicitações de auxílio aos profissionais. As intervenções foram realizadas por meio de estímulo e orientações aos profissionais e aos pacientes. Utilizaram-se entre os instrumentos: Fichas de Orientações e de Fluxo e Carta da Pesquisa. Em uma das USF Intervenção, foi disponibilizado o Sistema Eletrônico de Referência e Contrarreferência. Realizou-se o acompanhamento, nas USF do estudo e no Sistema Nacional de Regulação (SISREG), do fluxo dos pacientes referenciados aos médicos especialistas no período de 1º de agosto de 2012 a 1º de dezembro de 2012. Foram feitas, visitas aos médicos especialistas que atenderam os pacientes referenciados e, ainda, busca ativa de pacientes que não retornaram ou retornaram sem a contrarreferência à USF de origem. Avaliou-se o número de referências, contrarreferências e os motivos do não retorno dos pacientes e de contrarreferências às três USF do estudo. Os dados obtidos foram analisados por meio do programa STATA, versão 11.0. Resultados: Do total de 6.218 atendimentos médicos, foram realizados 532 encaminhamentos aos médicos especialistas e 492 acompanhamentos de pacientes. A taxa de encaminhamentos foi de 8,56%. Foram solicitadas e agendadas mais consultas nas USF Intervenção. Dos encaminhamentos realizados, 54,27% consultas foram agendadas. Destas, retornaram 11,61% pacientes às USF de origem do encaminhamento. O tempo do retorno do paciente à USF de origem, após a emissão do encaminhamento de referência variou de 6 a 110 dias. O retorno dos pacientes à USF de origem ocorreu apenas nas USF Intervenção, e destes pacientes, praticamente a metade retornou com a contrarreferência de forma manual. Conclusões: O estudo evidenciou taxa de encaminhamentos de acordo com os parâmetros internacionais; dificuldades de acesso às consultas especializadas; baixo número de retornos de pacientes às USF de origem do encaminhamento; como também, que orientações e estímulo aos profissionais e aos pacientes influenciaram positivamente no retorno dos pacientes e de contrarreferências às USF de origem. Acredita-se ser factível implantar o sistema de referência e contrarreferência por meio eletrônico, que permite uma melhor comunicação entre os profissionais de forma segura e rápida e uma maior integração entre os serviços.

Inicialmente e apresentada uma breve retrospectiva da Política de Saúde no Brasil, tomando como ponto de partida a década de 1970. Em seguida são discutidos os conceitos que embasaram o estudo, tendo como eixo central a integralidade e a contextualização da referencia e contra-referência. Para desenvolvimento deste trabalho fez-se a opção pela metodologia qualitativa, utilizando como técnica a ser utilizada junto aos profissionais de saúde a entrevista semi estruturada, e a narrativa, técnica a ser aplicada junto aos usuários, possibilita a recapitulação da experiência através da combinação da seqüência verbal de sentenças com a sequência de eventos que de fato ocorreram. Os sujeitos participantes da pesquisa foram os profissionais de saúde (médicos, assistentes sociais, enfermeiros) e principalmente, os usuários destes serviços de saúde. As convergências permitiram vislumbrar que embora o sistema de referencia e contra-referência no município de Juiz de Fora apresente problemas estruturais em sua organização, ocultando dificuldades de integração entre os níveis de atenção, existem reais possibilidades de melhoria do mesmo, que serão abordados no interior deste estudo. / The aim of this study was to analyze the access in health through the reference and against-reference system in the city of Juiz de Fora, considering the dimensions: availability, acceptability, accessibility, functional adequacy, based on the perspective of the process of consolidation of the integrality principle in care of three levels of attention to health. At first, a brief retrospective of the Politics of Health in Brazil is presented, taking as starting point the decade of 1970. Afterwards, the concepts that supported the study were discussed, having as central pivot the integrality and the contextualization of the reference and against-reference. For the development of this study, the qualitative methodology was picked up, using as a technique to be used to the health professionals the half-structuralized interview, and the narrative, technique to be applied to the users that makes it possible the recapitulation of the experience through the combination of the verbal sequence of sentences with the sequence of events that in fact had occurred. Not only health professionals (social doctors, assistants, nurses) took part in this research but, mainly, the users of these health services. The convergences allowed to glimpse that despite the system of reference and against-reference in the city of Juiz de Fora presents structural problems as precarious organization, concealing difficulties of integration among the attention levels, there are real possibilities of improvement, that will be dealth with in this study.
