On using Directional Information for Parameter Space Decomposition in Ellipse Detection
No full textIn this paper we use the parametric polar representation to extend the application of edge directional information from circle to ellipse extraction. As a result we obtain a mapping which decomposes the parameter space required for ellipse extraction into two independent sub-spaces and one final histogram accumulator. The mapping includes the tangent of the angle of the first and second directional derivatives. These tangents are computed by considering edge direction at two border points. We show that the use of gradient information for parameter space decomposition avoids the intensive point labelling imposed by geometric constraints used by other approaches
Does education cause participation in politics?
No full textIn most studies of political behavior in Western countries, it is found that
individuals with higher education participate to a greater extent in political activities
than individuals with lower levels of education. According to the conventional view,
education increases skills and knowledge but also affects political interest and political
efficacy; factors that all in turn trigger political participation. This dissertation tests two
alternative explanations to the conventional view. The first alternative – the relative
education model – claims that the social status gained by education drives participation
and not the educational experience. According to the second alternative explanation –
the pre-adult socialization model – the relationship is largely due to self-selection effects.
It suggests that pre-adult factors heavily affect both educational choice as well as
political participation in adulthood. The first three papers evaluate the relative
education model while the last two papers deal with the pre-adult socialization model.
The first paper deals with the research question: Is the relative education model
supported in the Swedish context? The second paper deals directly with the causal
mechanism: Does social network position mediate the effect of education on political
participation? The third article brings the discussion on the relative education model
further by providing the first country comparative test of the relative education model,
using data from 37 countries. Hence, it deals with the research question: Is the effect of
education on political participation absolute or relative in a comparative perspective?
The three first articles present evidence in favor of the relative education model. The
fourth paper employs matching techniques on data from the UK to mimic an
experimental test of the causal effect of higher education. It deals with the question: Is
college education a cause or a proxy for political participation? This paper contributes
to the discussion by using a more extensive set of pre-adult covariates than previous
studies, including important information on childhood cognitive ability. The fifth paper
moves from length of education to testing the impact of type of education. It presents a
panel study that follows Swedish adolescents over time during the first year in the
gymnasium (upper secondary level) in order to answer the question: Does type of
education affect political participation? The findings of both paper four and five point in
favor of the pre-adult socialization model; education seems to be a proxy rather than a
cause for political participation. Taken together, the five papers provide weak evidence
that the educational experience directly causes participation. Thus, the dissertation
challenges the conventional view on how education is related to participation

A Lagrangian sub-grid model for the dispersion of clouds of tracers
No full textTurbulence models are expected to satisfy the conflicting requirements of accuracy and computational efficiency. Here we discuss a new model that was recently developed in order to accurately and efficiently describe the dynamic of a clouds of tracers particles in Large Eddy Simulations of homogeneous and isotropic turbulent flows. The models incorporates the multi-scale nature of time and space turbulent velocity correlations that are essential in order to correctly reproduce the relative dispersion of multi-particle clouds. The model can be seen as an off-grid solver for the Eulerian velocity field at the positions of a given number of Lagrangian tracers that self-consistently move with it. Extensions to non homogeneous and isotropic turbulence as well as to the dynamics of particles will be discussed
Rate of breakup of small inertial aggregates in homogeneous turbulence
No full textThe hydrodynamic breakup of small inertial aggregates in homogenous and isotropic turbulence is studied through numerical simulations. Small inertial aggregates are subject to shear stress caused by the local velocity gradient and drag stress caused by the relative velocity of the aggregate and the fluid flow. In our simulations, we follow aggregates moving through the flow and record the total stress acting on them. Breakup is assumed to occur when the total stress overcomes a predefined threshold representing the aggregate strength. By determining how long it takes for an aggregate to reach a stress exceeding its strength for the first time, we are able to derive a breakup rate. It is found that with increasing aggregate inertia, the drag stress rapidly becomes the dominant stress resulting in an increase of the breakup rate with increasing the aggregate inertia
