Graph-based real-time fault diagnostics

A real-time fault detection and diagnosis capability is absolutely crucial in the design of large-scale space systems. Some of the existing AI-based fault diagnostic techniques like expert systems and qualitative modelling are frequently ill-suited for this purpose. Expert systems are often inadequately structured, difficult to validate and suffer from knowledge acquisition bottlenecks. Qualitative modelling techniques sometimes generate a large number of failure source alternatives, thus hampering speedy diagnosis. In this paper we present a graph-based technique which is well suited for real-time fault diagnosis, structured knowledge representation and acquisition and testing and validation. A Hierarchical Fault Model of the system to be diagnosed is developed. At each level of hierarchy, there exist fault propagation digraphs denoting causal relations between failure modes of subsystems. The edges of such a digraph are weighted with fault propagation time intervals. Efficient and restartable graph algorithms are used for on-line speedy identification of failure source components

On Causal Relations between Mental Organizer, Action under Mental Processes, and Social Environment

The purpose of the research was to study the relationships between mental organizers, action under mental process, and social environment through observation. A category system for each behavior was constructed and data were analyzed with matrices to find out kinds of root causes in causal dynamic. Reliability, subjectivity, and validity of observation were assessed. The coefficient of reliability was 0.937. The observation had about 11% subjectivity, and the frequencies were in the categories where they should be, mainly. Results indicate that there occurs causal variety. The causes are not stable. As an entity, the results show that it is possible to tackle mind processes through the causation. Furthermore, the processes are in series but they drop by in a parallel mode when the task becomes more difficult. However, the mindamic seems to have the greatest possible number of the degrees of freedom, simultaneously

On life, death and radical critique: A non-survival guide to the Brave New Higher Education for the intellectually pregnant

This paper joins the call to arms against the domestication of critique in organisation studies. It argues that we have become too pre-occupied with our professional survival to stand firm against the normalising pressure of the new higher education and its publish-or-perish machinery. We trade away too much radicalism in exchange for legitimacy, which results in widely accepted but toothless forms of critique. The paper draws on two contrasting metaphors of Huxley's Brave New World and intellectual pregnancy to illustrate some of the challenges faced by early-career academics entering the world of the Brave New Higher Education as academic ‘savages’. It discusses the almost imperceptible socialisation of the savage into the ‘rationalised myths’ of the brave new world to the point that alternatives become literally unthinkable. The paper suggests that we can fight this slippage and the associated domestication of critique by giving up our obsession with survival and by remembering/envisioning alternative realities, such as that of intellectual pregnancy deriving from the fragile idealism of the savage's doctoral world

ADR and Scottish commercial litigators : a study of attitudes and experience

Reports on the findings of a study of the use of alternative dispute resolution (ADR) by commercial litigators in Scotland. Analyses survey responses from commercial litigators on a range of issues, including: (1) their own knowledge of, training in, and actual experience of ADR; (2) reasons why they might recommend or decline use of ADR; (3) the outcome of ADR procedures they have used; (4) ADR as a business opportunity; (5) the role of courts in encouraging ADR; and (6) reasons why the take up of ADR in Scotland has not been greater

Archon Genomics X PRIZE Validation Protocol

This document is a collective assembly of techniques designed to test the quality and accuracy of 100 whole human genome sequences resulting from the $10 Million Archon Genomics X PRIZE (AGXP) competition. The purpose of this article is to enlist constructive criticism from the genomic and genetic community on the outlined approaches. The intent for the final version of this Validation Protocol is to become a useful standard by which to gauge the capabilities of whole genome sequencing technologies that emerge even after 2012
