Dymola and Modelica_EmbeddedSystems in Teaching-Experiences from a Project Course

This contribution presents experiences from a master level project course where a Modelica-based tool, Dymola, supporting embedded control system design has been used. In a recent initiative, the Modelica language has been enhanced to support modeling of embedded systems and code generation targeted at micro processors. Then new specification is sup-ported by, e.g., Dymola and enables wide range o

Natural Radiative Lifetimes of the 5p6s^(1)P_(1) , 5p6s^(3)P_(1,2), and 5p5d^(3)D_(1,2,3) Levels of the Sn I Spectrum by Zero Field Level Crossing Spectroscopy

Natural radiative lifetimes of some excited levels belonging to the 5 p 6 s and 5 p 5 d configurations have been measured by the Hanle method. Some of the levels could be optically excited only from the metastable 3 P 1 and 3 P 2 levels of the 5 p 2 ground configuration. These comparatively low-lying levels were sufficiently populated at the temperature necessary to produce a Sn atomic beam. The f

To move ahead - the extension of a life-world

This licentiate thesis is a monography complemented with one published article: “Interactive Design – the desire for autonomous upright mobility: A longitudinal case study, Technology and Disability 19 (2007) 213-224”. My hope is that the combination of the monographic part (with its phenomenological tone, personified and situated), and the more unbarked “Technology and Disability” article (with i

Recursive estimation of the continuous-time process parameters

The problem of continuous-time process parameter identification is considered. Filtered input-output process signals are used to create a linear differential equation governed by the same continuous-time process parameters. The estimation scheme is implemented by sampling the filtered signals and using a recursive least squares algorithm (RLS). The choice of filter leads to different parameter con
