  1. 1. Aspects of analysis of small-sample right censored data using generalized Wilcoxon rank tests

    Author : Marie-Louise Öhman; Hans Nyquist; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Censored generalized Wilcoxon rank test statistics; Variance estimation; Jackknifing; Influence function; Gross error sensitivity; Break-Down point; Sensitivity curve; Location parameter estimation; Product-Limit estimator and Monte-Carlo Simulation; Statistics; computer and systems science; Statistik; data- och systemvetenskap; Statistics; statistik;

    Abstract : The estimated bias and variance of commonly applied and jackknife variance estimators and observed significance level and power of standardised generalized Wilcoxon linear rank sum test statistics and tests, respectively, of Gehan and Prentice are compared in a Monte Carlo simulation study. The variance estimators are the permutational-, the conditional permutational- and the jackknife variance estimators of the test statistic of Gehan, and the asymptotic- and the jackknife variance estimators of the test statistic of Prentice.

  2. 2. Child–Robot Interaction in Education

    Author : Sofia Serholt; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; child–robot interaction; education; robotics; ethics; responsible research and innovation; stakeholders; ethics;

    Abstract : Advances in the field of robotics in recent years have enabled the deployment of robots in a multitude of settings, and it is predicted that this will continue to increase, leading to a profound impact on society in the future. This thesis takes its starting point in educational robots; specifically the kind of robots that are designed to interact socially with children. READ MORE

  3. 3. Unwrapping Cobol : Lessons in Crisis Computing

    Author : Linda Hilfling Ritasdatter; Susan Kozel; Maria Hellström Reimer; Florian Cramer; Nishant Shah; Malmö universitet; []
    Keywords : Crisis; Execution; Maintenance; Cobol; Automation; Global Flows; Y2K; Human Factor; Outsourcing; Development; Legacy Systems; Programming Languages; History of Computing; HCI; Software Wrapping; Postcolonial Studies; Diffraction; Broken world thinking; Grace Hopper; Media Archaeology; Debugging; Zombie Media; Obsolescence; Technological Development; Unsettling Ontologies; Fourth Industrial Revolution; Artificial Intelligence; Interaktionsdesign; Interaktionsdesign;

    Abstract : By engaging with COBOL, a detested and would-be obsolete programming language, the dark sides of automation are examined in this thesis: hidden workforces and computational infrastructures that are, in reality, central to the execution and maintenance of global economic and informational flows. Frictions within these flows are made more visible in moments of crisis when asymmetrical power structures are surfaced, as demonstrated in an analysis of the infamous Y2K Bug, its connection to the outsourcing boom in India and the legacy of COBOL.

  4. 4. Vortices in turbulent curved pipe flow-rocking, rolling and pulsating motions

    Author : Athanasia Kalpakli Vester; P. Henrik Alfredsson; Ramis Örlü; Nils Tillmark; Knud Meyer; KTH; []
    Keywords : Turbulence; curved pipes; swirling flow; pulsatile flow; time-resolved stereoscopic particle image velocimetry; hot-wire anemometry; proper orthogonal decomposition; turbocharger;

    Abstract : This thesis is motivated by the necessity to understand the flow structure of turbulent flows in bends encountered in many technical applications such as heat exchangers, nuclear reactors and internal combustion engines. Flows in bends are characterised by strong secondary motions in terms of counter-rotating vortices (Dean cells) set up by a centrifugal instability. READ MORE

  5. 5. Perceiving agents : Pluralism, interaction, and existence

    Author : Erik Lagerstedt; Serge Thill; Maria Riveiro; Paul Hemeren; Ron Chrisley; Högskolan i Skövde; []
    Keywords : HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Interaction Lab ILAB ; Interaction Lab ILAB ;

    Abstract : Perception is a vast subject to study. One way to approach and study it might therefore be to break down the concept into smaller pieces. Specific modes of sensation, mechanisms, phenomena, or contexts might be selected as the proxy or starting point for addressing perception as a whole. READ MORE
