1. 6. Validation and time series analysis of global stratospheric data sets

   Författare :Ashley Jones; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; OSIRIS; MIPAS; remote sensing; data assimilation; Trend; stratosphere; ozone; linear regression; Odin; validation;

   Sammanfattning : The depletion of ozone from the stratosphere and the impact of global warming have been identified as phenomena caused as a result of anthropogenic activity. Scientists are thus trying to find quicker and more reliable ways to analyse these environmental problems. LÄS MER

3. 7. On the Design and Validation of Fault Containment Regions in Distributed Communication Systems

   Författare :Håkan Sivencrona; RISE; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault handling and membership agreement; Byzantine faults; asymmetric faults; fault injection; time-triggered protocol; fault containment regions; slightly-out-of-specification faults; validation;

   Sammanfattning : This thesis has a two fold focus where the first is an evaluation of a time-triggered communication protocol implementation, TTP-C1, which was stressed by use of heavy-ion fault injection. The gathered result showed a novel type of failures, earlier known only from theory, so-called slightly-out-of-specification faults, that manifested as Byzantine failures with resulting system inconsistence.

4. 8. Definition and validation of requirements management measures

   Författare :Annabella Loconsole; Jürgen Börstler; Björn Regnell; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Requirement; Measures; Volatility; Theoretical Validation; Empirical Validation; Prediction Model; Correlational Study; Subjective Estimation.; Software engineering; Programvaruteknik;

   Sammanfattning : The quality of software systems depends on early activities in the software development process, of which the management of requirements is one. When requirements are not managed well, a project can fail or become more costly than intended, and the quality of the software developed can decrease. LÄS MER

5. 9. An approach to systems engineering tool data representation and exchange

   Författare :Erik Herzog; Anders Törne; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; engineering processes; information systems; data exchange; data representation; COTS; Information technology; Informationsteknologi;

   Sammanfattning : Over the last decades computer based tools have been introduced to facilitate systems engineering processes. There are computer based tools for assisting engineers in virtually every aspect of the systems engineering process from requirement elicitation and analysis, over functional analysis, synthesis, implementation and verification.

7. 10. An Open Architecture Approach for the Design and Development of Web and Mobile Software

   Författare :Bahtijar Vogel; Arianit Kurti; Marcelo Milrad; Tommi Mikkonen; Andreas Kerren; Kari Systä; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; open architecture; flexibility; evolvability; customizability; extensibility; web and mobile software; open standards; open source; dynamic requirements; dynamic changes; heterogeneous device environments; GQM; Data- och informationsvetenskap; Computer and Information Sciences Computer Science; Computer Science; Datavetenskap; Media Technology; Medieteknik;

   Sammanfattning : The rapid evolution of web and mobile technologies as well as open standards are important ingredients for developing open software applications. HTML5, affordable electronics, and connectivity costs are some of the trends that drive the web towards an open platform and lead to an increased use of distributed applications. LÄS MER
