Att vara universitetslärare

Väldigt roligt är det att få skriva om just detta. Det är ju universitetslärare jag varit i halva mitt liv. Under ständigt funderande över vad jag gör och vad det är bra för. Vilka sammanhang jag finns i. Här följer ett litet urval av mina erfarenheter, tankar och drömmar - de flesta framtidsinriktade.

Tracking time-variant cluster parameters in MIMO channel measurements

This paper presents a joint clustering-and-tracking framework to identify time-variant cluster parameters for geometry-based stochastic MIMO channel models. The method uses a Kalman filter for tracking and predicting cluster positions, a novel consistent initial guess procedure that accounts for predicted cluster centroids, and the well-known KPowerMeans algorithm for cluster identification. We te

Bundle Adjustment using Conjugate Gradients with Multiscale Preconditioning

Bundle adjustment is a key component of almost any feature based 3D reconstruction system, used to compute accurate estimates of calibration parameters and structure and motion configurations. These problems tend to be very large, often involving thousands of variables. Thus, efficient optimization methods are crucial. The traditional Levenberg Marquardt algorithm with a direct sparse solver can be

Transport Phenomena Coupled by Chemical Reactions in Methane Reforming Ducts

Mass, heat and momentum transport processes are strongly coupled with catalytic chemical reactions in a methane steam reforming duct. In this paper, a threedimensional calculation method is developed to simulate and analyze reforming reactions of methane, and the effects on various transport processes in a steam reforming duct. The results show that the design and operating parameters grouped as c

Variations in indoor temperature in residential apartments of different size and building category

In a case study, comprising 1177 residential apartments with 3248 rooms, temperature registrations every 15th minute in all living-rooms and bedrooms, during one year, in the system for individual metering and billing of space heating costs, were analyzed. The apartments were divided into two categories, apartment blocks from 1960th and row houses from about 1990. Apartments mean temperatures and

The function of art students' use of studio conversations in relation to their artwork

The article focuses on individual students’ studies within a practicebased MFA program in visual art in Sweden. The individual cases of studying that form the basis for this investigation, represent a particularly autonomous and self-directed kind of studying. Although the kind of autonomy and selfdirection varies between visual art programs, as well as its extent, these are largely qualities that
