The objective of the dissertation thesis has been the information-lexical analysis of Czech medical reports and the usability of international classification systems in the Czech healthcare environment. The analysis of medical reports has been based on the attributes of the Minimal Data Model for Cardiology (MDMC). Narrative medical reports and structured medical reports from the ADAMEK software application have been used. For the thesis SNOMED CT and ICD-10 classification systems have been used. There has been compared how well attributes of MDMC are recorded in narrative and structured medical reports. The language analysis of the Czech narrative medical reports has been made. A new application for measuring diversity in medical reports written in any language is proposed. The application is based on the general concepts of diversities derived from f-diversity, relative f- diversity, self f-diversity and marginal f-diversity. The thesis has come to the conclusion that using a free text in medical reports is not consistent and not standardized. The standardized terminology would bring benefits to physicians, patients, administrators, software developers and payers and it would help healthcare providers as it could provide complete and easily accessible information that belongs to the process of...

Open Platform Communication Unified Architecture, or OPC UA, is a world-leading communication protocol specializing in unifying and automating production systems communication. In 2018 the OPC Foundation, an industrial consortium, started the OPC UA Field eXchange initiative to develop the current protocol to extend the reach of the communication down to field level devices like sensors and actuators. This paper explores whether OPC UA FX software can be implemented and integrated with HMS Networks’ product AnyBus CompactCom M40.  The problem formulation stems from the future need for factory communication. For factories to compete, they need to adapt and keep up with the technological progression. OPC UA FX is based on decentralized communication where devices transmit data to each other by distributing the load over the entire system.   The purpose of this report is to, based on the Open62541 implementation, develop software that extends OPC UA with PubSub functionality and methods that enable two or more instances to run as an FX application, meaning that the program publishes and subscribes data simultaneously. Once the software is developed, we integrate it on an AnyBus CompactCom 40 module. This will work as a communication prototype that proves that it is possible to extend OPC UA with FX into HMS Networks’ products.  Open62541 is used to gather libraries and methods needed for OPC UA development. The software is developed using C in Visual Studios and integrated into the hardware using Eclipse.  The result in the form of software was a connection-oriented data exchange, based on the OPC UA information model, where two or more instances can publish and subscribe to information simultaneously. HMS Networks can use the result on their way to implementing OPC UA FX in their products.  In conclusion, the Open62541 implementation is beneficial when developing the OPC UA protocol. The software is complete, but it could not be fully integrated into the CompactCom module. The achieved application is still useful for the development of HMS Network’s products that might use the protocol. / Open Platform Communication Unified Architechure, eller OPC UA, är ett av de världsledande kommunikationsprotokoll som är specialiserat i att förena kommunikation i produktionssystem. 2018 startade OPC Foundation, ett industriellt konsortium, ett initiativ vid namn OPC UA Field eXchange med målet att utvekcla det nuvarande protokollet så att det kan användas till kommunikation på låg nivå, exempelvis mellan sensorer och ställdon. Denna rapport utforskar ifall det är möjligt att utveckla protokollet och integrera det i HMS Networks modul AnyBus CompactCom 40.  Problemformluleringen baseras på framtida behov hos fabriker relaterat till automatisering. För att konkurrera framöver behöver fabriker anpassa sig till utvecklingen inom automatisering. OPC UA FX fokuserar på decentralierad kommunikation mellan enheter som fältanordning, maskin och moln samtidigt för att belastningen ska delas upp över hela systemet. Samtidigt som enheter i industiella nätverket fritt ska kunna överföra data mellan varandra oberoende vilken tillverkare som skapat enheten.   Syftet med arbetet är att, baserat på Open62541, utveckla PubSub teknologi med metoder som möjlighetsgör att två eller fler instanser av en FX applikation ska kunna transportera data genom att prenumerera på och publicera data samtidigt. När mjukvaran fungerar är tanken att integrera mjukvaran på en AnyBus CompactCom 40 modul för att bevisa att implementationen är möjlig i ett praktiskt sammanhang.  Open62541 används för att inkludera nödvändiga OPC UA bibliotek, funktionalitet och datatyper. Protokollet utvecklas i C i en VisualStudio miljö och integreras med hjälp av Eclipse. Resultatet i form av mjukvara var en kopplings intriktat data utbyte, baserad på OPC UA information modell, där en eller två instanser av ett program kan publicera och prenumerera på data samtidigt. HMS Networks kan använda resultatet i arbetet att implementera OPC UA FX i deras produkter. ​Sammanfattningsvis är Open62541 ett mycket användbart verktyg för utvekcling av OPC UA protokol. Dessvärre lyckades inte integrationen av mjukvaran i CompactCom modulen helt och hållet, men det som åstadkommits i arbetet kan i hög grad användas för fortsatt utveckling av OPC UA FX i HMS Networks produkter.

Purpose: The purpose of this paper is to examine how material, vital for the designprocess (supporting documents) is handled throughout the entire process. From obtaining the material from the document-administer until the material is transformed and applicable in a BIM-software in the design-process. Method: The first method is a case study that contains semi-structured interviews with one large as well as one small design-firm in Sweden, but also the biggest client regarding infrastructure in Sweden. Secondly, the other part of this thesis work is to perform an experiment containing two parts where the first one is to examine supporting material of an ongoing infrastructure-project and evaluate the quality, as well as constructing conversion rules to evaluate how supporting documents can be implemented. Findings: All the respondents in the conducted survey reported that supporting material regarding electric-, telecommunication- and fibre-optic cables were supporting material with the lowest degree of accuracy. Furthermore, the most used file-format is DWG, but file-formats like PDF, JPG, XML and LAS are also file-formats that is used according to the respondents. All the respondents suggest that a standardised way of using supporting documents would be an efficient way of standardising the process. The findings from the experiment concluded that the most used file-format used as supporting material is DWG (79%), followed by PDF (21 %). The quality varied between different providers. Supporting material provided straight from the contractor in DWG had great or excellent quality. Material as PDF/JPG needed to be processed in order to be used in a BIM-software. The implementing of conversion rules resulted in way of implementing these. In order to use this, the supporting document needs to be digital, in this case as DWG-files. Well established ways of using colours, layers and names in the CAD-software is vital. Implications: In order to make the way of handling the supporting material more efficient, a standardised way of handling these need to be used, as well as standardised file-formats. By making the supporting material digital, this will make the material more accessible, thus is the quality of e.g. PDF and JPG “not sufficient” because a BIMuser must convert these files manually, which provide one source of error. Therefore, these files lack interoperability. Regarding the material provided by the contractor, the design-firm need to have direct communication with the provider of the supporting material to take advantage of DWG-files and use the same file-formats, layers etc., to reduce the time it takes to convert the supporting documents manually. Limitations: A limitation is that only one large and one small design-firm is analysed. One part of a complete BIM-software is used, so the external validity is low, because the result may only be used in another small design-firm with the same project configurations and programmes. The experiment, where Conversion Rules were examined did only embrace wells (water-systems). / Syfte: Syftet med detta examensarbete är att ta reda på hur underlagshanteringen ser ut igenom hela processen från tillhandahållning av underlaget till implementering i projekteringsprocessen. Metod: Den första är en fallstudie som består av kvalitativa semi-strukturerade intervjuer med en stor och en liten konsultfirma inom projekteringsprocessen, såväl som den största beställaren av infrastrukturprojekt i Sverige. Den andra delen är ett experiment som är uppdelat i två delar där den första är att ta reda på hur underlag ser ut och bedöma dessa i ett pågående infrastrukturprojekt. Den andra delen är att upprätta så kallade konverteringsregler för att importera underlag i en BIM-mjukvara. Resultat: Samtliga respondenter i intervjuerna svarade att underlag gällande el-, teleoch fiberoptikkablar är underlag med lägst grad av träffsäkerhet/noggrannhet. Vidare svarade respondenterna att DWG är filformatet som oftast används. Andra filformat som PDF, JPG, XML och LAS är även det filformat som används. Samtliga respondenter redogjorde även för vissa åtgärder som kan vidtas för att standardisera underlagshantering i branschen. Däribland efterfrågas en standardisering av underlagshantering gällande lagernamn, färger, filformat osv. I experimentet visade det sig att underlag i DWG-format svarar för (79 %) av underlagen, följt av PDF (21 %). Kvaliteten varierade mellan olika källor, där underlag tillhandahållna direkt av entreprenören i DWG hade bra eller utomordentlig kvalitet. Underlag i from av PDF/JPG måste omvandlas för hand för att kunna används i en BIM-mjukvara. Implementeringen av konverteringsregler resulterade i en arbetsgång för att implementera konverteringsregler i projekteringsprocessen. För att göra detta krävs underlag i DWG-format. Konsekvenser: För att göra underlagshanteringsprocessen mer effektiv, behövs ett standardiserat sätt att använda dessa, såväl som filformat. Genom att digitalisera underlag bidrar detta till att höja antagningsgraden i CAD- och BIM-mjukvaror. Således är kvalitén av exempelvis PDF och JPG ”inte tillräckligt” på grund av att en person manuellt måste omvandla dessa filer, som bidrar till en felkälla. Därav är interoperabiliteten bristfällig. Gällande material tillhandahållen av entreprenören, så måste en god kommunikation upprättas mellan de båda parterna för att dra nytta av underlag i DWG, och använda samma filformat, lager etcetera, för att reducera tidsåtgången i att konvertera exempelvis PDF-filer manuellt. Begränsningar: Endast en stor och en lite konsultfirma analyseras. Endast en del av en komplett BIM-mjukvara används, därav låg extern validitet, då resultatet endast kan appliceras i en annan liten konsultfirma med samma projekt-konfigurationer och program. I experimentet där konverteringsregler utreddes inkluderades endast brunnar (VA).

La maitrise de la complexité croissante tant de nos organisations socioéconomiques que de nos systèmes et infrastructures technologiques, impose des systèmes informatiques de plus en plus intégrés. L’organisation de nos sociétés avancées ne pourrait plus se développer dans des conditions raisonnables sans le support des technologies de l’information. Les différents systèmes d’information s’intègrent ainsi de plus en plus en un maillage informationnel formant ainsi un système de systèmes qui se complexifie de jour en jour et de ce fait devient de plus en plus vital. Ces systèmes des systèmes doivent répondre à deux types d’objectifs : i) la réalisation d’un système par l’intégration de systèmes offerts par différents fournisseurs, ii) l’interopération de systèmes déjà en service en vue d’obtenir des propriétés nouvelles dues à leur coopération, généralement avec une augmentation d’efficacité. Ces objectifs et cette complexité ne peuvent être appréhendés par une démarche purement analytique. C’est pourquoi nous avons préconisé à travers cette thèse une solution de système de systèmes basée sur un graphe d'interopérabilité construit sur une comparaison hiérarchique ontologique. La mise en œuvre de cette approche à travers l’utilisation d’une plateforme d’agents mobile permet une recherche dynamique de services visant à satisfaire au mieux les critères de qualité exigés par l’utilisateur. / Mastering the increasing complexity of our socio-economic organizations and technology infrastructure requires more and more integrated information systems. The organization of our advanced societies could no longer grow on reasonable terms without the support of information technology.The different information systems belongs more and more to an informational meshing, forming in this way a complex system of systems which is getting complex day after day and because of that is becoming increasingly vital.This system of systems must meet two objectives: i) implementation of a system by integrating systems offered by different providers, ii) interoperation of systems already in use in order to obtain new properties due to their cooperation, usually with an efficiency increase.These objectives and this complexity can be grasped by a purely analytical approach. That is why we have advocated throughout this thesis a solution of system of systems based on an interoperability graph built on a hierarchical ontological comparison (foundation of trust). The platform of mobile agents associated with this system will implement a dynamic search of services which tries to satisfy the quality criteria required by the user.

Présenté dans la littérature comme une nouvelle technologie, le Cloud Computing est devenu incontournable dans la mise en place et la fourniture des services informatiques. Cette thèse s’inscrit dans le contexte de cette nouvelle technologie qui est en mesure de transformer la mise en place, la gestion et l’utilisation des systèmes d’information. L'adoption et la vulgarisation du Cloud ont été ralenties par la jeunesse même des concepts et l'hétérogénéité des solutions existantes. Cette difficulté d'adoption se manifeste par l'absence de standard, l'hétérogénéité des architectures et des API, le Vendor Lock-In imposé par les leaders du marché et des manques qui ralentissent la fédération. La motivation principale de la thèse est de simplifier l'adoption du cloud et la migration vers ses environnements et technologies. Notre objectif est de proposer des solutions d'interopérabilité et de fédération dans le Cloud. Le travail de recherche s’est aussi articulé autour de deux grands axes. Le premier concerne le rapprochement des réseaux du futur et des Clouds. Le deuxième axe concerne l'interopérabilité et la fédération entre solutions et services cloud. Une analyse de l’état de l’art sur le Cloud Computing et le Cloud Networking, a permis de confirmer des manques pressentis et de proposer deux architectures de fédération Cloud. La première architecture permet le rapprochement entre le Cloud Computing et le Cloud Networking. La seconde architecture facilite l'interopérabilité et le courtage de services Cloud. L'étude des deux architectures a fait ressortir deux composants primordiaux et essentiels pour assurer la fédération: une interface générique et un système d'échange de messages. Ces deux composants correspondent à deux contributions centrales de la thèse et reflètent l’ensemble des contributions (quatre au total) du travail de recherche / Presented in the literature as a new technology, Cloud Computing has become essential in the development and delivery of IT services. Given the innovative potential of Cloud, our thesis was conducted in the context of this promising technology. It was clear that the Cloud would change the way we develop, manage and use information systems. However, the adoption and popularization of Cloud were slow and difficult given the youth of the concepts and heterogeneity of the existing solutions. This difficulty in adoption is reflected by the lack of standard, the presence of heterogeneous architectures and APIs, the introduction of Vendor Lock-In imposed by the market leaders and the lack of cloud federation principles and facilitators. The main motivation for our PhD is to simplify the adoption of the cloud paradigm and the migration to cloud environments and technologies. Our goal has consequently been to improve interoperability and enable federation in the cloud. The thesis focused on two main areas. The first concerns the convergence of future networks and clouds and the second the improvement of federation and interoperability between heterogeneous cloud solutions and services. Based on our work in state of the art about Cloud Computing and Cloud Networking, we defined in this thesis two architectures for Cloud federation. The first architecture enables the merging (convergence) of Cloud Computing and Cloud Networking. The second architecture addresses interoperability between services and proposes cloud-brokering solutions. The study enabled the identification of two essential components for cloud federation, namely: a generic interface and a message exchange system. These two components have been two contributions of our thesis. The proposed federation architectures and these two components summarize the four major contributions of our work

Learning Management Systems (LMSs) are widely used in higher education to improve the learning, teaching, and administrative tasks for both students and instructors. Such systems enrich the educational experience by integrating a wide range of services, such as on-demand course material and training, thus empowering students to achieve their learning outcomes at their own pace. Courses in various sub-fields of Computer Science that seek to provide rich electronic learning (e-learning) experience depend on exercise material being offered in the forms of quizzes, programming exercises, laboratories, simulations, etc. Providing hands on experience in courses such as Internetworking could be facilitated by providing laboratory exercises based on virtual machine environments where the student studies the performance of different internet protocols under different conditions (such as different throughput bounds, error rates, and patterns of changes in these conditions). Unfortunately, the integration of such exercises and their tailored virtual environments is not yet very popular in LMSs. This thesis project investigates the generation of on-demand virtual exercise environments using cloud infrastructures and integration with an LMS to provide a rich e-learning in an Internetworking course. The software deliverable of this project enables instructors to dynamically instantiate virtual laboratories without incurring the overhead of running and maintaining their own physical infrastructure. This sets the foundations for a virtual classroom that can scale in response to higher system utilization during specific periods of the academic calendar. / Lärplattformar (eng. Learning Management Systems (LMS)) används i stor utsträckning för högre utbildning för att förbättra lärande, undervisning och administrativa uppgifter för både studenter och instruktörer. Sådana system berikar den pedagogiska erfarenheten genom att integrera ett brett utbud av tjänster, såsom on-demand kursmaterial och träning, vilket ger studenterna möjlighet att uppnå sina lärandemål i egen takt. Kurser inom olika delområden av datavetenskap som syftar till att ge en bred erfarenhet av elektroniskt lärande (e-learning) har träningsmaterial i form av frågesporter, programmeringsövningar, laboratorier, simuleringar etc. Praktiskt erfarenhet i kurser som Internetworking kan underlättas genom att tillhandahålla laboratorieövningar baserade på virtuella maskinmiljöer där studenten studerar prestanda för olika internetprotokoll under olika förhållanden (t.ex. olika gränsvärden, felfrekvenser och förändringsmönster under dessa förhållanden). Tyvärr är integrationen av sådana övningar och deras skräddarsydda virtuella miljöer ännu inte populär i LMSs. Detta examensarbete undersöker generering av virtuella träningsmiljöer på begäran med hjälp av molninfrastruktur och integration med en LMS för att ge ett rikt e-lärande i en Internetworking-kurs. Programvaran som levereras av detta projekt gör det möjligt för instruktörer att dynamiskt instansera virtuella laboratorier utan att behöva hantera sin egen fysiska infrastruktur. Detta sätter grunden för ett virtuellt klassrum som kan skala med högre systemutnyttjande under specifika perioder av den akademiska kalendern.

The challenge of interoperability is to retain model integrity when different software applications exchange and interpret model data. Transferring CAD data between heterogeneous CAD systems is a challenge because of differences in feature representation. A study by the National Institute for Standards and Technology (NIST) performed in 1999 made a conservative estimate that inadequate interoperability in the automotive industry costs them $1 billion per year. One critical part of eliminating the high costs due to poor interoperability is a neutral format between heterogeneous CAD systems. An effective neutral CAD format should include a current-state data store, be associative, include the union of CAD features across an arbitrary number of CAD systems, maintain design history, maintain referential integrity, and support multi-user collaboration. This research has focused on extending an existing synchronous collaborative CAD software tool to allow for a neutral, current-state data store. This has been accomplished by creating a Neutral Parametric Canonical Form (NPCF) which defines the neutral data structure for many basic CAD features to enable translation between heterogeneous CAD systems. The initial architecture developed begins to define a new standard for storing CAD features neutrally. The NPCF's for many features have been implemented in a multi-user interoperability program and work between NX and CATIA CAD systems. The 2D point, 2D line, 2D arc, 2D circle, 2D spline, 3D point, extrude, and revolve NPCF's will be specifically defined. Complex models have successfully been modeled and exchanged in real time and have validated the NPCF approach. Multiple users can be in the same part at the same time in different CAD systems and create and update models in real time.
