2. 1. Models and meaning : on management models and systems of meaning when implementing change

   Author : Jacob Hallencreutz; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management;

   Abstract : Change has become a vital business partner for many organizations. Survival of most organizations depends on their ability to implement adequate changes to support the organization. This thesis deals with questions about measurement systems, process based system models and organizational change with a specific focus on implementation challenges. READ MORE

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-speed railway bridges; Bridge dynamics; Running safety; Passenger comfort; Structural reliability; Meta-models; Surrogate models; Adaptive sampling; Reliability-based design optimization; Höghastighetsjärnvägsbroar; Brodynamik; Trafiksäkerhet; Passagerarkomfort; Konstruktioners tillförlitlighet; Metamodeller; Surrogatmodeller; Adaptiv sampling; Tillförlitlighetsbaserad designoptimering; Structural Engineering and Bridges; Bro- och stålbyggnad;

   Abstract : Increasing the operational speed of trains has attracted a lot of interest in the last decades and has brought new challenges, especially in terms of infrastructure design methodology, as it may induce excessive vibrations. Such demands can damage bridges, which in turn increases maintenance costs, endangers the safety of passing trains and disrupts passenger comfort. READ MORE

5. 3. Under the skin of change : meanings, models and management

   Author : Jacob Hallencreutz; Jan Forslin; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management;

   Abstract : For society at large, and organizations in particular, the magnitude, speed, impact, and unpredictability of change, are greater than ever before. But despite the need for unceasing transformation, there seems to be a general consensus between practitioners and scholars that few are successful when trying to lead organizational change.

6. 4. Analyzing Substation Automation System Reliability using Probabilistic Relational Models and Enterprise Architecture

   Author : Johan König; Lars Nordström; Sebastian Lehnhoff; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability analysis; substation automation; Enterprise Architecture; probabilistic analysis; Probabilistic Relational Models; Bayesian networks; software reliability; failure rates; fault tree analysis;

   Abstract : Modern society is unquestionably heavily reliant on supply of electricity. Hence, the power system is one of the important infrastructures for future growth. READ MORE

7. 5. Statistical analysis and simulation methods related to load-sharing models

   Author : Patrik Rydén; Yuri Belyaev; Uwe Jensen; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Non-parametric and parametric estimation; load-sharing models; asymptotic distribution; martingale; resampling; life testing; reliability;

   Abstract : We consider the problem of estimating the reliability of bundles constructed of several fibres, given a particular kind of censored data. The bundles consist of several fibres which have their own independent identically dis-tributed failure stresses (i.e.the forces that destroy the fibres). READ MORE
