Scalable Distributed Kalman Filtering for Mass-Spring Systems

This paper considers Kalman Filtering for massspring systems. The aim is a scalable distributed implementation where nodes communicate in a sparse pattern and the state estimate for each node is available locally and usable for control. The focus is on translation invariant systems, to make use of the powerful results available based on Fourier Transform methods. In this case it is known that Kalm

Modelling of Granular Materials

The aim of this doctoral study is to develop and implement a material model for granular materials. The course of this work was concentrated upon a non-associated plasticity model with yield surface and the flow potential expressed in terms of the mean stress p and the third stress invariants I3. The plastic work hardening in the model depends upon both plastic volumetric and deviatoric strain inc

Data Quality Quantification for Time Domain IP Data Acquired along a Planned Tunnel near Oslo, Norway

Tests were done measuring resistivity and time domain induced polarisation using standard multi-core cable spreads and a special layout with separate cable spreads for transmitting current and measuring potentials. For both types of cables spreads both normal and reciprocal measurements were done in order to estimate the measurement errors. The tests were done along a planned tunnel stretch outsid

Humanism and Lutheran Confessional Culture

The seventeenth century saw the culmination of what has traditionally been called “Lutheran Orthodoxy”. Earlier a rather underestimated period, the time of “Lutheran Orthodoxy” has started to attract a fairer share of attention within the concept of Confessional Culture (recently coined by Professor Dr. Thomas Kaufmann). An enormously important but sometimes slightly overlooked part of this cultur
