1. Aspects of analysis of small-sample right censored data using generalized Wilcoxon rank tests
Sammanfattning : 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. Child–Robot Interaction in Education
Sammanfattning : 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. LÄS MER
3. Unwrapping Cobol : Lessons in Crisis Computing
Sammanfattning : 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. Vortices in turbulent curved pipe flow-rocking, rolling and pulsating motions
Sammanfattning : 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. LÄS MER
5. Perceiving agents : Pluralism, interaction, and existence
Sammanfattning : 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. LÄS MER
