Biased magnetic materials in RAM applications

The magnetization of a ferro- or ferri-magnetic material has been modeled with the Landau-Lifshitz-Gilbert (LLG) equation. In this model demagnetization effects are included. By applying a linearized small signal model of the LLG equation, it was found that the material can be described by an effective permeability and with the aid of a static external biasing field, the material can be switched b

Fel mossman

Note on the right identification of the Tollund man belonging to the "bog people" cf Seamus Heaney, who confuses The Grauballe man and the Tollund man in a poem.

Engineering protein-carbohydrate interactions - lessons from natural and evolved carbohydrate binding modules

Protein-carbohydrate interactions are of central role in all living organism. In the studies presented in this thesis several strategies for engineering such interactions have been investigated. In the first study the binding affinity of a carbohydrate binding module (CBM) was improved a 100-fold through affinity maturation. Also, in that study it was discovered that all the selected, matured muta

Optimal Linear Joint Source-Channel Coding with Delay Constraint

The problem of joint source-channel coding is considered for a stationary remote (noisy) Gaussian source and a Gaussian channel. The encoder and decoder are assumed to be causal and their combined operations are subject to a delay constraint. It is shown that, under the mean-square error distortion metric, an optimal encoder-decoder pair from the linear and time-invariant (LTI) class can be found
