  1. 1. Coherence and Reliability: Studies in Bayesian Epistemology

    Författare :Stefan Schubert; Teoretisk filosofi; []
    Nyckelord :HUMANIORA; HUMANITIES; coherence; Bayesian epistemology; reliability; higher order beliefs; reliability-conduciveness; truth-conduciveness; formal coherence theory; witness scenarios;

    Sammanfattning : In this thesis the connection between coherence and reliability is investigated. The question may be phrased as follows: does the fact that a set of testimonies is coherent imply that the witnesses who have reported these testimonies are reliable? The same question may also be expressed in terms of beliefs: does the fact that a set of beliefs is coherent imply that the beliefs were reliably produced? Traditionally, coherence theorists have thought that coherence is connected to truth, but in this dissertation the thesis is that it is rather connected to reliability. LÄS MER

  3. 2. Structural Reliability and Identification with Stochastic Simulation - Application to Railway Mechanics

    Författare :Sadegh Rahrovani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; model reduction; time-integration; finite element model; sleeper-ballast load characterization; stochastic simulation; Bayesian system identification;

    Sammanfattning : System identification of structures based on measured response data can play a key role in improving reliability based structural designs. However, the experimental limitations of in situ tests and uncertainties of required model complexity together with the inverse nature of system identification give rise to a number of challenging issues.

    Sammanfattning : We consider the problem of estimating the failure stresses of bundles (i.e. the tensile forces that destroy the bundles), constructed of several statisti-cally similar fibres, given a particular kind of censored data. LÄS MER

  7. 5. Program Analysis for Performance and Reliability

    Författare :Jacob Lidman; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; static dynamic program analysis; abstract interpretation; performance; reliability;

    Sammanfattning : The increased demand for computing power has lead designers to put an ever increasing number of cores on processor dies. This advance has been made possible through miniaturization and effectivization of the underlying semi-conductor technology. As a by-product, however, the resulting computer systems are more vulnerable to interference. LÄS MER
