Controle eletrônico das etapas do processo de planejamento de pacientes em radioterapia / Electronic control of the steps of the planning process of patients in radiotherapy

Brito, Carlos de 20 October 2017 (has links)
Em diversos serviços de radioterapia brasileiros há a premente necessidade de sistematização de processos que ainda hoje, mesmo com acesso à tecnologia da informação, é realizada manualmente. Este fato acontece com o controle dos pacientes em planejamento radioterápico onde os dados de todas as etapas do processo são inseridos em um quadro físico conforme executadas. Esses dados consistem desde o agendamento da tomografia de planejamento até a liberação do mesmo para o tratamento. O objetivo deste estudo é o desenvolvimento de um software para controle eletrônico de pacientes em processo de planejamento radioterápico, substituindo o quadro físico utilizado atualmente. Foi utilizado para este estudo a técnica de elicitação de requisitos, que resulta em um documento de requisitos que serve de base para a modelagem do sistema através de diagramas UML e modelagem conceitual do banco de dados MySql e posteriormente a utilização da técnica de mapeamento objeto relacional (MOR). A consistência nos dados permite acesso seguro e confiável à esses dados, facilita a obtenção de dados estatísticos e agiliza o processo de planejamento, já que de posse de estatísticas consistentes é possível a identificação de gargalos no processo e sua resolução com maior rapidez. O resultado deste estudo é um software e banco de dados que integra todas as informações do processo de planejamento radioterápico. / In Brazilian radiotherapy departments there is a pressing need for systematization of processes, that even today with the access of information technology is performed manually. The control of the patients in radiotherapy planning with the data of all the steps of the process are inserted in a physical board as they are executed. These data consist of scheduling since the planning tomography until the release of the patient for the treatment. The objective of this study is the development of a software for electronic control of patients in radiotherapy planning process, replacing the physical board currently used. The requirements for the elicitation technique was used for this study, which results in a requirements document that serves as the basis for modeling the system through UML diagrams and conceptual modeling of the MySql database and after using the relational object mapping technique (MOR). The data consistency allows secure and reliable access to these data, facilitates the collection of statistical data and streamlines the planning process, this consistent statistics allow the identification of limitation in the process and faster resolution. The result of this study is a software and database that integrates all the information of the radiotherapy planning process.

Informationsaustausch im interdisziplinären Entwicklungsprozess

Holowenko, Olaf, Oehm, Lukas, Majschak, Jens-Peter, Ihlenfeldt, Steffen 17 May 2018 (has links) (PDF)
Die Entwicklung moderner produktionstechnischer Systeme, z. B. Verpackungs- oder Werkzeugmaschinen, erfolgt aufgrund derer steigender Komplexität zunehmend in interdisziplinären Projektteams. Diesen gehören Entwickler unterschiedlichster Fachbereiche (Domänen) an, wie beispielsweise Vertriebsmitarbeiter, Konstrukteure, Arbeitswissenschaftler, Informatiker oder Designer. Sie alle generieren im iterativen Entwicklungsprozess Inhalte, die wiederum für andere Entwickler als Arbeitsgrundlage notwendig sind und an diese übergeben werden müssen. Der erforderliche, interdisziplinäre Informationsaustausch stellt heute immer noch ein Kernproblem bei der Maschinenentwicklung dar. In der vorliegenden Arbeit wird die aktuelle Situation bei der Informationsübergabe im Entwicklungsprozess analysiert, der Bedarf nach Assistenzsystemen abgeleitet und eine neue Herangehensweise zur Unterstützung der interdisziplinären Entwicklung als theoretische Basis für die Erstellung der Software „Smarte Werkbank“ vorgestellt.

Analys och vidareutveckling av lyftok till Dendro Lift ABs lyftbock LB2.5

Levin, Niklas January 2016 (has links)
Dendro Lift AB är ett företag som utvecklar och tillverkar lyftbockar för tunga lyft. Tillsammans med konstruktionsföretaget Mk3D tar Dendro Lift AB fram ett nytt koncept för en lyftbocksmodell till lyft av stödbenstruckar. Syftet med examensarbetet är att vidareutveckla lyftoket till lyftbocken LB2.5 genom att minska materialanvändningen och bereda plats för ett nytt damm- och petskydd. Målet med examensarbetet är att ta fram underlag för tillverkning av ett nytt lyftok som uppfyllde ställda krav. Vid genomförandet av examensarbetet gjordes en förstudie kring dimensioneringskraven, spänningar i skruvförband, utvärdering av spänningar i svetsar, finita elementmetoden och hållbar utveckling. Förstudien följdes av analyser och vidareutveckling av lyftoket med finita elementanalyser i mjukvaran ANSYS Workbench 17.2. Modeller togs fram i Autodesk Inventor Professional 2016. Resultatet visade att det nya lyftokets plåttjocklek kunde minskas från 15 mm till 10 mm och därmed reducerades materialanvändningen med cirka 66 kg. I det nya lyftoket bereddes även plats för en ny typ av damm- och petskydd. Slutsatsen blir att det gamla lyftoket är överdimensionerat och mindre material kan användas utan att funktionen i lyftoket försämras. / Dendro Lift AB is a company that develops and manufactures lifting jacks for heavy lifting. Along with the construction company Mk3D, Dendro Lift AB introduces a new concept for a lifting trestle designed to lift stackers. The aim of the thesis is to further develop the yoke fitted in the lifting jack LB2.5 by reducing its material use and make way for a new dust and finger protection. The goal of the thesis is to develop manufacturing plans for the production of a new lifting yoke that meets the applicable requirements. In the implementation of the thesis there was a preliminary study on the design requirements, tension in bolted joints, evaluation of stresses in welds, finite element method analysis and sustainable development. The pilot study was followed by analysis and further development of the yoke with finite element analysis in software ANSYS Workbench 17.2. Models were developed in Autodesk Inventor Professional 2016. The results showed that the plate thickness could be reduced from 15 mm to 10 mm in the new yoke and thus reduced material usage by about 66 kg. The new yoke was also prepared for a new type of dust and finger protection. The conclusion was that the old yoke is oversized and less material can be used without compromising the operation of the lifting jack.
