Markering av dolda objekt på väg genom användning av förstärkt verklighet.

Sjödin, Filip January 2019 (has links)
Enligt en rapport från trafikverket förekommer kollisioner vid väghållningsarbeten mellan väghållningsfordon och objekt täckta av väglag. Dessa trafikolyckor kan leda till personskador, skador på infrastruktur och skador på de inblandade väghållnings-fordonen. Som lösning på detta problem har möjligheten att visuellt markera de dolda objekten med förstärkt verklighet undersökts. Olika implementationer och metoder för användning av förstärkt verklighet studerades först för att få en bra upp-fattning om ämnet. En applikation utvecklades därefter till mobiltelefon med opera-tivsystemet Android i utvecklingsmiljön Unity. För förstärkt verklighet i applikat-ionen användes en natural feature tracking implementation av ARCore. Positioner-ingstester utfördes med Mobiltelefonens inbyggda GPS vilket visade en stor felmar-ginal. Applikationen utgår därför från en fast startpunkt inmätt med geodetisk mät-utrustning för ökad positioneringsnoggrannhet. För markering av de dolda objekten användes en lösning med cirkelbaserat skapande av tredimensionella objektmarkörer där cirklarnas radie utgick från startpositionen. Användning av applikationen gav va-rierande resultat beroende på den trafiksituation den används i och avståndet från startpositionen. Objektens position markeras tydligast i situationer där mobiltelefo-nen närmar sig det objekt som ska markeras på en väg i en riktning parallellt med cirkelns radie. Sämre tydlighet uppnåddes i situationer där mobiltelefonen närmar sig på en väg med en riktning parallell med cirkelns tangent eller på öppna ytor likt parkeringsplatser. Positioner för olika testobjekt mättes också med geodetisk mätut-rustning för hög precision för att få tillgång till en testmiljö där pålitligt data kunde hämtas upprepade gånger. Resultaten visar att den implementation av ARCore som finns i applikationen är känslig för avbrott i spårning av omgivningen och kan leda till fel i positionering. Ett fel i avståndsberäkningen finns också i programmet. Där-för är vidareutveckling och mer tester ett krav innan applikationen kan fungera i skarpt läge. / According to a report from Trafikverket collisions occur in road maintenance work with road maintenance vehicles and objects hidden by road conditions. These traffic accidents can lead to personal injury, damage to infrastructure and damage to the road maintenance vehicles involved. As a solution to this problem the possibility of visually marking the hidden objects with the use of augmented reality has been ex-amined. Different implementations and methods for use of augmented reality were first studied to get a good understanding of the subject. An application for mobile telephone was developed with the development platform Unity. The targeted oper-ating system for the mobile telephone was Android. A natural feature tracking imple-mentation of ARCore was used to bring features of augmented reality to the applica-tion. Tests were done to measure the precision of the mobile telephone’s GPS which showed a large margin for error. The application therefore uses a fixed start-ing location which has been measured with geodetic-measuring equipment for in-creased positioning accuracy. To visualize the position of the hidden objects a solu-tion with circle based creation of three-dimensional object markers was used where the radius of the circles originated from the starting position. Use of the application led to varied results which depended on the traffic situation and distance from the start position. The positions of the objects are marked more clearly in situations where the mobile phone is approaching the objects on a road and in a direction par-allel to the circle’s radius. Lower accuracy was generally achieved in situations where the mobile phone was approaching the objects on a road in a direction paral-lel to the circle’s tangent or in open areas like a parking lot. Positions for different test objects were also measured to achieve a test-environment where reliable data could be extracted repeatedly. The results of this study showed that the implemen-tation of ARCore used in this application is sensitive to disruption in the real-world registration of the mobile telephone’s position, which can lead to errors in position-ing. An error in calculating the distance to the objects also exists in the application. Therefore, before the application can be used in a real-life situations further devel-opment and tests are required.

Fúze a analýza multidimenzionálních medicínských obrazových dat / Fusion and Analysis of Multidimensional Medical Image Data

Peter, Roman January 2013 (has links)
Analýza medicínských obrazů je předmětem základního výzkumu již řadu let. Za tu dobu bylo v této oblasti publikováno mnoho výzkumných prací zabývajících se dílčími částmi jako je rekonstrukce obrazů, restaurace, segmentace, klasifikace, registrace (lícování) a fúze. Kromě obecného úvodu, pojednává tato disertační práce o dvou medicínsky orientovaných tématech, jež byla formulována ve spolupráci s Philips Netherland BV, divizí Philips Healthcare. První téma je zaměřeno na oblast zpracování obrazů subtrakční angiografie dolních končetin člověka získaných pomocí výpočetní X-Ray tomografie (CT). Subtrakční angiografie je obvykle využívaná při podezření na periferní cévní onemocnění (PAOD) nebo při akutním poškození dolních končetin jako jsou fraktury apod. Současné komerční metody nejsou dostatečně spolehlivé už v předzpracování, jako je například odstranění pacientského stolu, pokrývky, dlahy, apod. Spolehlivost a přesnost identifikace cév v subtrahovaných datech vedoucích v blízkosti kostí je v důsledku Partial Volume artefaktu rovněž nízká. Automatické odstranění kalcifikací nebo detekce malých cév doplňujících nezbytnou informaci o náhradním zásobení dolních končetin krví v případě přerušení hlavních zásobujících cév v současné době rovněž nesplňují kritéria pro plně automatické zpracování. Proto hlavním cílem týkající se tohoto tématu bylo vyvinout automatický systém, který by mohl současné nedostatky v CTSA vyšetření odstranit. Druhé téma je orientováno na identifikaci patologických změn na páteři člověka v CT obrazech se zaměřením na osteolytické a osteoblastické léze u jednotlivých obratlů. Tyto změny obvykle nastávají v důsledků postižení metastazujícím procesem rakovinového onemocnění. Pro detekci patologických změn je pak potřeba identifikace a segmentace jednotlivých obratlů. Přesnost analýzy jednotlivých lézí však závisí rovněž na správné identifikaci těla a zadních segmentů u jednotlivých obratlů a na segmentaci trabekulárního centra obratlů, tj. odstranění kortikální kosti. Během léčby mohou být pacienti skenováni vícekrát, obvykle s několika-mesíčním odstupem. Hodnocení případného vývoje již detekovaných patologických změn pak logicky vychází ze správné detekce patologií v jednotlivých obratlech korespondujících si v jednotlivých akvizicích. Jelikož jsou příslušné obratle v jednotlivých akvizicích obvykle na různé pozici, jejich fúze, vedoucí k analýze časového vývoje detekovaných patologií, je komplikovaná. Požadovaným výsledkem v tomto tématu je vytvoření komplexního systému pro detekci patologických změn v páteři, především osteoblastických a osteolytických lézí. Takový systém tedy musí umožnovat jak segmentaci jednotlivých obratlů, jejich automatické rozdělení na hlavní části a odstranění kortikální kosti, tak také detekci patologických změn a jejich hodnocení. Ačkoliv je tato disertační práce v obou výše zmíněných tématech primárně zaměřena na experimentální část zpracování medicínských obrazů, zabývá se všemi nezbytnými kroky, jako je předzpracování, registrace, dodatečné zpracování a hodnocení výsledků, vedoucími k možné aplikovatelnosti obou systému v klinické praxi. Jelikož oba systémy byly řešeny v rámci týmové spolupráce jako celek, u obou témat jsou pro některé konkrétní kroky uvedeny odkazy na doktorskou práci Miloše Malínského.

The agreement found between the sensory profiles of children 3-10 years and their parents

Geyser, Elsje 15 October 2009 (has links)
M.Sc.(Occupational Therapy), Faculty of Health Sciences, University of the Witwatersrand, 2009 / Title: The agreement found between the sensory profiles of children 3-10 years and their parents Author: Elsje Geyser Promoter: Denise Franszen School: Therapeutic Sciences Faculty: Health Sciences Degree: MSc.OT Key Concepts: Sensory modulation dysfunction, sensory processing disorder, high threshold, low threshold, sensory profile, low registration behaviour, sensory seeking behaviour, sensory sensitive behaviour, sensation avoiding behaviour. In order to treat a child with sensory modulation disorder (SMD), the impact of SMD on the child’s occupational sphere should be taken into account. This includes the effect of SMD in the parent on the child’s development and behaviour. This study determined the probability of agreement between the parent and child’s sensory profiles. A quantitative, cross sectional study design established the sensory profiles of 81 children and their parents. Results indicated a moderate probability that a child with SMD may have a parent with SMD. A moderate to high probability existed for a parent with SMD to have a child with SMD. This supports the supposition that there is a hereditary component to SMD, with learned sedentary behavioural patterns. The treatment implications include considering the parent’s reaction to their own sensory thresholds and the influence this has on the child’s treatment and learnt behaviour.

Odométrie visuelle directe et cartographie dense de grands environnements à base d'images panoramiques RGB-D / Direct visual odometry and dense large-scale environment mapping from panoramic RGB-D images

Martins, Renato 27 October 2017 (has links)
Cette thèse se situe dans le domaine de l'auto-localisation et de la cartographie 3D des caméras RGB-D pour des robots mobiles et des systèmes autonomes avec des caméras RGB-D. Nous présentons des techniques d'alignement et de cartographie pour effectuer la localisation d'une caméra (suivi), notamment pour des caméras avec mouvements rapides ou avec faible cadence. Les domaines d'application possibles sont la réalité virtuelle et augmentée, la localisation de véhicules autonomes ou la reconstruction 3D des environnements.Nous proposons un cadre consistant et complet au problème de localisation et cartographie 3D à partir de séquences d'images RGB-D acquises par une plateforme mobile. Ce travail explore et étend le domaine d'applicabilité des approches de suivi direct dites "appearance-based". Vis-à-vis des méthodes fondées sur l'extraction de primitives, les approches directes permettent une représentation dense et plus précise de la scène mais souffrent d'un domaine de convergence plus faible nécessitant une hypothèse de petits déplacements entre images.Dans la première partie de la thèse, deux contributions sont proposées pour augmenter ce domaine de convergence. Tout d'abord une méthode d'estimation des grands déplacements est développée s'appuyant sur les propriétés géométriques des cartes de profondeurs contenues dans l'image RGB-D. Cette estimation grossière (rough estimation) peut être utilisée pour initialiser la fonction de coût minimisée dans l'approche directe. Une seconde contribution porte sur l'étude des domaines de convergence de la partie photométrique et de la partie géométrique de cette fonction de coût. Il en résulte une nouvelle fonction de coût exploitant de manière adaptative l'erreur photométrique et géométrique en se fondant sur leurs propriétés de convergence respectives.Dans la deuxième partie de la thèse, nous proposons des techniques de régularisation et de fusion pour créer des représentations précises et compactes de grands environnements. La régularisation s'appuie sur une segmentation de l'image sphérique RGB-D en patchs utilisant simultanément les informations géométriques et photométriques afin d'améliorer la précision et la stabilité de la représentation 3D de la scène. Cette segmentation est également adaptée pour la résolution non uniforme des images panoramiques. Enfin les images régularisées sont fusionnées pour créer une représentation compacte de la scène, composée de panoramas RGB-D sphériques distribués de façon optimale dans l'environnement. Ces représentations sont particulièrement adaptées aux applications de mobilité, tâches de navigation autonome et de guidage, car elles permettent un accès en temps constant avec une faible occupation de mémoire qui ne dépendent pas de la taille de l'environnement. / This thesis is in the context of self-localization and 3D mapping from RGB-D cameras for mobile robots and autonomous systems. We present image alignment and mapping techniques to perform the camera localization (tracking) notably for large camera motions or low frame rate. Possible domains of application are localization of autonomous vehicles, 3D reconstruction of environments, security or in virtual and augmented reality. We propose a consistent localization and 3D dense mapping framework considering as input a sequence of RGB-D images acquired from a mobile platform. The core of this framework explores and extends the domain of applicability of direct/dense appearance-based image registration methods. With regard to feature-based techniques, direct/dense image registration (or image alignment) techniques are more accurate and allow us a more consistent dense representation of the scene. However, these techniques have a smaller domain of convergence and rely on the assumption that the camera motion is small.In the first part of the thesis, we propose two formulations to relax this assumption. Firstly, we describe a fast pose estimation strategy to compute a rough estimate of large motions, based on the normal vectors of the scene surfaces and on the geometric properties between the RGB-D images. This rough estimation can be used as initialization to direct registration methods for refinement. Secondly, we propose a direct RGB-D camera tracking method that exploits adaptively the photometric and geometric error properties to improve the convergence of the image alignment.In the second part of the thesis, we propose techniques of regularization and fusion to create compact and accurate representations of large scale environments. The regularization is performed from a segmentation of spherical frames in piecewise patches using simultaneously the photometric and geometric information to improve the accuracy and the consistency of the scene 3D reconstruction. This segmentation is also adapted to tackle the non-uniform resolution of panoramic images. Finally, the regularized frames are combined to build a compact keyframe-based map composed of spherical RGB-D panoramas optimally distributed in the environment. These representations are helpful for autonomous navigation and guiding tasks as they allow us an access in constant time with a limited storage which does not depend on the size of the environment.

Traitement joint de nuage de points et d'images pour l'analyse et la visualisation des formes 3D / Joint point clouds and images processing for the analysis and visualization of 3D models

Guislain, Maximilien 19 October 2017 (has links)
Au cours de la dernière décennie, les technologies permettant la numérisation d'espaces urbains ont connu un développement rapide. Des campagnes d'acquisition de données couvrant des villes entières ont été menées en utilisant des scanners LiDAR (Light Detection And Ranging) installés sur des véhicules mobiles. Les résultats de ces campagnes d'acquisition laser, représentants les bâtiments numérisés, sont des nuages de millions de points pouvant également contenir un ensemble de photographies. On s'intéresse ici à l'amélioration du nuage de points à l'aide des données présentes dans ces photographies. Cette thèse apporte plusieurs contributions notables à cette amélioration. La position et l'orientation des images acquises sont généralement connues à l'aide de dispositifs embarqués avec le scanner LiDAR, même si ces informations de positionnement sont parfois imprécises. Pour obtenir un recalage précis d'une image sur un nuage de points, nous proposons un algorithme en deux étapes, faisant appel à l'information mutuelle normalisée et aux histogrammes de gradients orientés. Cette méthode permet d'obtenir une pose précise même lorsque les estimations initiales sont très éloignées de la position et de l'orientation réelles. Une fois ces images recalées, il est possible de les utiliser pour inférer la couleur de chaque point du nuage en prenant en compte la variabilité des points de vue. Pour cela, nous nous appuyons sur la minimisation d'une énergie prenant en compte les différentes couleurs associables à un point et les couleurs présentes dans le voisinage spatial du point. Bien entendu, les différences d'illumination lors de l'acquisition des données peuvent altérer la couleur à attribuer à un point. Notamment, cette couleur peut dépendre de la présence d'ombres portées amenées à changer avec la position du soleil. Il est donc nécessaire de détecter et de corriger ces dernières. Nous proposons une nouvelle méthode qui s'appuie sur l'analyse conjointe des variations de la réflectance mesurée par le LiDAR et de la colorimétrie des points du nuage. En détectant suffisamment d'interfaces ombre/lumière nous pouvons caractériser la luminosité de la scène et la corriger pour obtenir des scènes sans ombre portée. Le dernier problème abordé par cette thèse est celui de la densification du nuage de points. En effet la densité locale du nuage de points est variable et parfois insuffisante dans certaines zones. Nous proposons une approche applicable directement par la mise en oeuvre d'un filtre bilatéral joint permettant de densifier le nuage de points en utilisant les données des images / Recent years saw a rapid development of city digitization technologies. Acquisition campaigns covering entire cities are now performed using LiDAR (Light Detection And Ranging) scanners embedded aboard mobile vehicles. These acquisition campaigns yield point clouds, composed of millions of points, representing the buildings and the streets, and may also contain a set of images of the scene. The subject developed here is the improvement of the point cloud using the information contained in the camera images. This thesis introduces several contributions to this joint improvement. The position and orientation of acquired images are usually estimated using devices embedded with the LiDAR scanner, even if this information is inaccurate. To obtain the precise registration of an image on a point cloud, we propose a two-step algorithm which uses both Mutual Information and Histograms of Oriented Gradients. The proposed method yields an accurate camera pose, even when the initial estimations are far from the real position and orientation. Once the images have been correctly registered, it is possible to use them to color each point of the cloud while using the variability of the point of view. This is done by minimizing an energy considering the different colors associated with a point and the potential colors of its neighbors. Illumination changes can also change the color assigned to a point. Notably, this color can be affected by cast shadows. These cast shadows are changing with the sun position, it is therefore necessary to detect and correct them. We propose a new method that analyzes the joint variation of the reflectance value obtained by the LiDAR and the color of the points. By detecting enough interfaces between shadow and light, we can characterize the luminance of the scene and to remove the cast shadows. The last point developed in this thesis is the densification of a point cloud. Indeed, the local density of a point cloud varies and is sometimes insufficient in certain areas. We propose a directly applicable approach to increase the density of a point cloud using multiple images

CAD-Based Pose Estimation - Algorithm Investigation

Lef, Annette January 2019 (has links)
One fundamental task in robotics is random bin-picking, where it is important to be able to detect an object in a bin and estimate its pose to plan the motion of a robotic arm. For this purpose, this thesis work aimed to investigate and evaluate algorithms for 6D pose estimation when the object was given by a CAD model. The scene was given by a point cloud illustrating a partial 3D view of the bin with multiple instances of the object. Two algorithms were thus implemented and evaluated. The first algorithm was an approach based on Point Pair Features, and the second was Fast Global Registration. For evaluation, four different CAD models were used to create synthetic data with ground truth annotations. It was concluded that the Point Pair Feature approach provided a robust localization of objects and can be used for bin-picking. The algorithm appears to be able to handle different types of objects, however, with small limitations when the object has flat surfaces and weak texture or many similar details. The disadvantage with the algorithm was the execution time. Fast Global Registration, on the other hand, did not provide a robust localization of objects and is thus not a good solution for bin-picking.

Vilande lagfart vid köp av del av fastighet : Avskaffande av expeditionsavgiften

Svedman, Linda, Svens, Josefina January 2019 (has links)
Ansökan om lagfart som blir vilandeförklarad vid köp av del av fastighet kan användas för att säkra ägandet. En expeditionsavgift à 825 kronor skall erläggas av köparen när vilandebeslutet tas. Ytterligare en expeditionsavgift à 825 kronor skall erläggas av köparen när den vilande lagfarten blir en beviljad lagfart eller avslagen. Vid motbeslutet uppskov skall ingen expeditionsavgift erläggas för när beslut om uppskov tas. En expeditionsavgift à 825 kronor skall erläggas av köparen när uppskovet blir en beviljad lagfart eller avslagen.  Denna studie är begärd av Lantmäteriet och grundar sig i frågan om ett avskaffande av expeditionsavgiften skall ske. Syftet med denna studie är att öka kunskapen kring vilande lagfart vid köp av del av fastighet. Studien undersöker även om expeditionsavgiften påverkar köparens tillvägagångssätt vid köp av del av fastighet. Målet med denna studie är att klargöra hur fastighetsmarknaden ser på expeditionsavgiften för lagfartsansökan som får ett vilandebeslut.    För att ta reda på svaret till studiens vetenskapliga frågeställningar har två metoder tillämpats. En kvalitativ studie där intervjuer med tre olika målgrupper har valts ut samt en kvantitativ studie där statistik ur Fastighetsregistret har undersökts.    Studiens resultat visar på brist i kunskap om vilande lagfart hos studiens målgrupper. Resultatet visar även att fastighetsmäklare och banktjänstemän sällan rekommenderar försäljning av del av fastighet. Det brister även i informationen ut till kunder och berörda parter om i vilket skede en lagfartsansökan kan göras vid köp av del av fastighet. Handläggare från Fastighetsinskrivningen letar efter orsaker till att lagfartsansökan skall få ett uppskov istället för ett vilandebeslut för att kunden skall slippa den dubbla expeditionsavgiften, vilket tyder på ett ohållbart system. Studiens diskussion omfattar de åsikter som framkommit från studiens resultat. Dessutom diskuteras hur ett avskaffande av expeditionsavgiften för vilande lagfart skulle påverka köp av del av fastighet.    Slutsatsen för studien är att fastighetsmarknaden överlag ser på vilande lagfart vid köp av del av fastighet som ett misstag eller som att något saknas istället för en trygghet. Samt att användning av vilande lagfart vid köp av del av fastighet inte skulle ändras vid köp av del av fastighet. / An application for registration of ownership that is dormant declared when buying a part of a property can be used to secure ownership. An expedition fee of SEK 825 must be paid by the buyer when the dormant registration of ownership is taken. An expedition fee of SEK 825 is to be paid by the buyer when the dormant registration of ownership becomes a registration of ownership or becomes rejected. In the case of a respite decision no expedition fee is paid for the respite decision. An expedition fee of SEK 825 shall be paid by the buyer when the respite decision becomes a registration of ownership or becomes rejected.  This study is requested by Lantmäteriet and is based on the question of whether an abolition of the expedition fee should take place. The purpose of this study is to increase the knowledge of dormant registration of ownership during the process of buying a part of a property. The study also examines whether the expedition fee affects the buyer's approach when buying a part of a property. The aim of this study is to clarify how the real estate market looks at the expedition fee for the application for registration of ownership that receives a dormant decision. To find out the answer to study's research questions, two methods have been applied. A qualitative study in which interviews with three different target groups have been selected and a quantitative study in which statistics from the Real Property Register have examined. The results of the study show a lack of knowledge of dormant registration of ownership among the study's target groups. The result also shows that realtor and bank clerk rarely recommend sale of a part of a property. It is also a lacking information to customers and interested parties about the stage at which an application for registration of ownership can be made when buying part of a property. Registration clerks at Registration of real property are looking for reasons why the application for registration of ownership should receive a respite decision instead of a dormant decision for the customer to avoid the double expedition fee, which indicates an unsustainable system. The study's discussion covers the opinions that emerged from the study's results. In addition, it is discussed how the abolition of the expedition fee for dormant registration of ownership enforcement would affect the purchase buying a part of a property. The conclusion for the study is that that real estate market generally looks at dormant registration of ownership during the process of buying a part of a property as a mistake or as something missing instead of a security. And that the use of dormant registration of ownership when buying a part of a property should not be changed.

Codificação automática das causas de morte e seleção da causa básica de morte: a adaptação para o Brasil do software Iris / Automatic coding cause of death and selection for underlying cause of death: an adaptation of Iris software to Brazil

Martins, Renata Cristófani 27 July 2012 (has links)
Introdução - Uma das formas de se aumentar a qualidade das informações sobre causas de morte é automatizar o processo de sua elaboração. O software Iris é um dos mecanismos disponíveis para esse fim. Suas principais características é que ele segue as regras internacionais de mortalidade e ele é independente de idioma. Objetivo - Elaborar para o Iris um dicionário na língua portuguesa e avaliar a sua completitude para a codificação das causas de morte. Método - O dicionário criado com dados do arquivo eletrônico do volume 1 da CID-10 e com o Tesauro da Classificação Internacional de Atenção Primária. Foi utilizado o Iris V4.0.34 e, como codificação manual, o que o Programa de Aprimoramento das Informações de Mortalidade no Município de São Paulo (PRO-AIM) da Secretaria Municipal de Saúde de São Paulo escreveu nas declarações de óbito. Caso o Iris não codificasse as causas de morte, ajustes eram feitos no dicionário ou na tabela de padronização. Resultado - O Iris é capaz de codificar as causas de morte e selecionar a causa básica de morte, ambas automaticamente, é um software recente que está em constantes adequações, é independente de idioma e para usá-lo em cada país é necessário realizar somente um dicionário de causas de morte. No teste para avaliação da primeira versão do dicionário em português, o Iris apresentou um desempenho satisfatório. Foi capaz de codificar diretamente 50,6 por cento das declarações de óbito e, após ajustes e acréscimos no dicionário e na tabela de padronização, o software codificou todas as linhas em 94,44 por cento das declarações. Das declarações não codificadas completamente 89,19 por cento delas tinham algum diagnóstico contido no capítulo XX da CID-10. O Iris apresentou 63,1 por cento de concordância nas declarações de óbito pareadas considerando todas as causas de morte com códigos completos de 4 caracteres da CID-10. Conclusão - A realização dos ajustes no dicionário ou na padronização faz parte do processo de desenvolvimento do dicionário e que esse processo é continuo. Com as novas versões do Iris e atualizações e aprimoramento da codificação das causas externas, avanços serão feitos para que ele seja mais compatível com a realidade brasileira. Somado a isso, as futuras versões do Iris com um dicionário mais desenvolvido podem satisfazer as necessidades de codificação automática e melhorar a precisão dos dados de causa morte paras estudos de saúde pública. / Introduction - One way to increase the quality of causes-of-death statistics is to use computers for applying the rules systematically. Iris software is an available system for this purpose. Its main characteristics are that it follows international rules of mortality and it is language independent. Objective - Produce a Portuguese dictionary for Iris and assess its completeness of coding of causes of death. Methods - The creation of the dictionary used two sources: the electronic file of volume 1 of ICD-10 and Thesaurus of Classificação Internacional de Atenção Primária. Was used Iris V4.0.34 and for manual coding the codes at the Programa de Aprimoramento das Informações de Mortalidade no Município de São Paulo (PRO-AIM) of Secretaria Municipal de Saúde of São Paulo has written on death certificates. If Iris couldnt codify the causes of death, adjustments were made in the dictionary or standardization table. Results - Iris is able to encode causes of death and select the underlying cause of death, either automatically; is a recent software that is in constant adjustments; is a language independent software and to use it in your country you need only dictionary of causes of death. In the test for evaluation the first version of the Portuguese dictionary Iris showed satisfactory performance. He was able to code directly for 50.6 per cent of death certificates and, after adjustments and additions in the dictionary and standardization table, the software coded all lines in 94.44 per cent of death certificate. The statements do not fully coded 89.19 per cent had a diagnosis contained in Chapter XX of ICD-10. Iris presented 63,1 per cent agreement on paired death certificates considering all causes of death and 4-digit ICD-10 code level. Conclusion - making adjustments in the dictionary or the standardization is part of the development process of the dictionary and that this process is ongoing. With new Iris versions and updates in the management of the coding external causes, progress will be made to make it more compatible with the Brazilian reality. Added to this, future versions of Iris with a dictionary more developed can meet the needs of auto-tagging and improve the accuracy of data causes death to public health studies.

Sistemas especialistas modulados e abrangentes para a gestão de operações. / Modulate and wide experts systems to the operations management.

Barrella, Wagner Däumichen 12 December 2000 (has links)
A existência de novas condições econômicas e de trabalho tem conduzido as empresas a uma modernização de técnicas e metodologias para a resolução de problemas em Engenharia de Produção. Embora seja rápido o surgimento de novas ferramentas de informática e haja uma grande preocupação, no sentido de empregar a informática como suporte à tomada de decisões, o que se tem notado é que a utilização dos computadores nas empresas não tem sido feita na plenitude de suas possibilidades, ou seja, os usuários (especialmente os engenheiros) fazem uso de programas especialistas para chegarem a decisões isoladas e, posteriormente, transferem os resultados obtidos para outros aplicativos e/ou realização das análises. Este trabalho desenvolveu estudos multidisciplinares que envolvem as novas ferramentas oferecidas pelos avanços da Informática e pelos modernos conceitos de administração e otimização de processos, estudados em Engenharia de Produção. Tais estudos foram direcionados para a obtenção de resultados práticos que possam ser rapidamente aplicados nas empresas brasileiras, ou seja, dentro do contexto financeiro-tecnológico nacional. Estas pesquisam procuraram documentar qual é o formato do sistema, para que sejam capazes de facilitar e automatizar o planejamento da produção de uma indústria ou de uma empresa de serviços. Pretendeu-se, assim, registrar os conceitos e filosofias necessários para se construir uma ferramenta para otimização de processos produtivos que resolva, ou atenue, eventuais problemas causados por restrições nadisponibilidade de recursos (equipamento, mão-de-obra, material e tempo) ou de outra natureza. / The existence of new economic and work conditions has been driving the companies to a modernization of techniques and methodologies for resolution of problems in Production Engineering. Although be fast the appearance of new computer science tools and there be a great concern in the sense of using the computer science as support to the taking of decisions, which one has been noticing is that the use of the computers in the companies has not been made in the fullness of its possibilities, that is to say, the users (especially the engineers) make use of expert programs for they arrive to isolated decisions, and later, they transfer the results obtained for another applications and/or accomplishment of the analyses. This research developed multidisciplinaries studies involving the new tools offered by the progresses of the Computer Science and by the modern administration concepts, and optimization of processes studied by the Production Engineering. Such studies were addressed for the obtaining of practical results that they can be quickly applied in the Brazilian companies, that is to say, inside the national financial-technological context. Those researches tried to document which is the format of the system, so that they are capable to facilitate and to automate the planning of the production of an industry or company of services. It was intended like this to register the concepts and necessary philosophies to build a tool for optimization of productive processes that it solves, or attenuate, eventual problems caused by restrictions in the readiness of resources (equipment, work-hand, material and time) or by another nature.
