1. 1. A Fault Classification Approach to Software Process Improvement

   Författare :Kennet Henningsson; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Software development; Process improvement; Fault classification;

   Sammanfattning : The research presented is motivated by the demand for process improvement for companies active within software development. High demands on software quality are a reality. At the same time, short development time and low effort consumption are required. This stresses the necessity for process improvement. LÄS MER

3. 2. Faults and their influence on the dynamic behaviour of electric vehicles

   Författare :Daniel Wanner; Annika Stensson Trigell; Lars Drugge; Jonas Sjöberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fault classification; vehicle dynamics; electric vehicle; failure; fault-tolerant control; reconfiguration; fault handling; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik;

   Sammanfattning : The increase of electronics in road vehicles comes along with a broad variety of possibilitiesin terms of safety, handling and comfort for the users. A rising complexityof the vehicle subsystems and components accompanies this development and has tobe managed by increased electronic control. LÄS MER

4. 3. On Evaluating Test Techniques in an Industrial Setting

   Författare :Sigrid Eldh; Hans Hansson; Sasikumar Punnekkat; Joachim Wegener; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fault; Failure; Fault injection; Test Techniques; ; Computer science; Datavetenskap; Datavetenskap;

   Sammanfattning : Testing is a costly and an important activity in the software industry today. The systems are becoming more complex and the amount of code is constantly increasing. The majority of systems need to rely on its testing to show that it works, is reliable, and performs according to user expectations and specifications. LÄS MER

5. 4. On Fault Detection, Diagnosis and Monitoring for Induction Motors

   Författare :Mohammed Obaid Mustafa; Mohamed El Hachemi Benbouzid; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model based fault detection and diagnosis; Model free fault detection; Set Membership Identification SMI ; Uncertainty Bounds Violation Method; Model based Support Vector Classification; Linear and Nonlinear Classification; Minimum Volume Ellipsoid method; Broken Rotor Bars; Faults of Induction Motors; Three phase induction motor; Reglerteknik; Control Engineering;

   Sammanfattning : In this thesis, multiple methods and different approaches have been established and evaluated successfully, in order to detect and diagnose the faults of induction motors (IMs). The aim of this thesis is to present novel fault detection and isolation methods for the case of induction machines that would have the merit to be implemented online and being characterized by specific novel capabilities, when compared with the existing techniques.

7. 5. On Data Mining and Classification Using a Bayesian Confidence Propagation Neural Network

   Författare :Roland Orre; KTH; []
   Nyckelord :data mining; bcpnn; classification; neural network;

   Sammanfattning : The aim of this thesis is to describe how a statisticallybased neural network technology, here named BCPNN (BayesianConfidence Propagation Neural Network), which may be identifiedby rewriting Bayes' rule, can be used within a fewapplications, data mining and classification with credibilityintervals as well as unsupervised pattern recognition.BCPNN is a neural network model somewhat reminding aboutBayesian decision trees which are often used within artificialintelligence systems.
