In the last decades this image has begun to change, especially as regards geographical mobility, while our knowledge of social mobility of rural preindustrial Europe is still rudimentary. This study focus on social attainment and mobility in a rural community of nineteenth century so

Analysis of Approximations to Dual Control

The dual control problem for time-varying or non-linear systems is inherently analytically and computationally untractable due to the demand of alternating minimizations and mean value computations. Hence, it has to be approached using approximations leading to suboptimal dual control. The core of the successful approximative controller is its ability to be able to consider future changes in the d

This doctoral dissertation deals with a phenomenon that is often referred to in sports, but still poorly understood from a scientific angle: psychological momentum (PM). No consensus has been agreed on how to label this phenomenon, and other terms such as momentum or behavioural momentum (BM) are often used interchangeably.

Methods for understanding the mobile user experience

Methods for observing what happens in the wild are nonetheless being employed because they bring results that the traditional methods of evaluation do not yield. In this paper we describe and discuss methods used at our lab for understanding the mobile user experience. These methods range from quantitative to qualitative evaluation, and
