1. 1. Enterprise Architecture for Information System Analysis : Modeling and assessing data accuracy, availability, performance and application usage

   Författare :Närman Per; Mathias Ekstedt; Pontus Johnson; Sjaak Brinkkemper; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Enterprise Architecture; Metamodeling; Decision-making; Data Accuracy; Service Availability; Service Performance; Technology Acceptance Model; Task Technology Fit;

   Sammanfattning : Decisions concerning IT systems are often made without adequate decision-support. This has led to unnecessary IT costs and failures to realize business benefits. The present thesis presents a framework for analysis of four information systems properties relevant to IT decision-making. LÄS MER

3. 2. Airborne cognitive systems in search of an appropriate context: Studies of the introduction of new technology in aviation using a cognitive systems engineering approach

   Författare :Örjan Goteman; Ergonomi och aerosolteknologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lufttransportteknik; Air transport technology; Safety; RNAV; Pilot; Automation Modes; HUD; Datalink; Cognition; Automation; Aviation;

   Sammanfattning : Abstract Technology is always designed for an assumed user in an assumed context. In commercial aviation, these design assumptions are clearly spelt out in that both crew and equipment are certificated for a specific operation as stated in the aircraft flight manual. LÄS MER

4. 3. Scalable Streaming Graph and Time Series Analysis Using Partitioning and Machine Learning

   Författare :Zainab Abbas; Vladimir Vlassov; Peter Van Roy; Paris Carbone; Vasiliki Kalavri; Vincenzo Massimiliano Gulisano; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stream processing; graph processing; time series; big data; machine learning; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Recent years have witnessed a massive increase in the amount of data generated by the Internet of Things (IoT) and social media. Processing huge amounts of this data poses non-trivial challenges in terms of the hardware and performance requirements of modern-day applications. LÄS MER

5. 4. Model Based Fault Diagnosis : Methods, Theory, and Automotive Engine Applications

   Författare :Mattias Nyberg; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Model based fault diagnosis is to perform fault diagnosis by means of models. An important question is how to use the models to construct a diagnosis system. To develop a general theory for this, useful in real applications, is the topic of the first part of this thesis. LÄS MER

7. 5. Computational fluid dynamics in theoretical simulations of elastohydrodynamic lubrication

   Författare :Torbjörn Almqvist; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

   Sammanfattning : The work presented in this thesis concerns computer simulations of lubrication processes, and the main part deals with simulations in the elastohydrodynamic lubrication (EHL) regime. The thesis summarises the work performed in the five papers referred to as Paper A, B, C, D and E. LÄS MER
