Pollen-based quantitative reconstruction of land-cover change in Europe from 11,500 years ago until present - A dataset suitable for climate modelling

The major objective of this thesis was to produce descriptions of the land vegetation-cover in Europe for selected time windows of the Holocene (6000, 3000, 500, 200, and 50 calendar years before present (BP=1950)) that can be used in climate modelling. Land vegetation is part of the climate system; its changes influence climate through biogeophysical and biogeochemical processes. Land use such as

Reducing computational complexity of branch metric calculations in a trellis decoder

Trellis decoding is widely used, in this present day of communication and data storage, in a wide variety of applications such as decoding convolution codes, baseband detection for wireless systems and also to detect recorded data. This is achieved by implementing the Viterbi algorithm. This paper presents various methodologies of reducing the computational complexity of the branch metric unit in

Towards manufacturing of perfect magnets

Abstract in UndeterminedThe paper describes a magnetizing machine for producing permanent magnets of desired magnetization pattern by use of feedback control. This will in theory mean that an ideal magnetization pattern can be realized, what could be described as a perfect magnet. The machine is to be used for applications requiring high accuracy magnets in terms of the shape of the magnetized are

Comparison between infrared and Raman spectroscopic parameters on maturing rabbit bone

The molecular composition of the organic and inorganic matrices of bone undergoes alterations during maturation. The aim of this study was to compare Fourier transform infrared (FT-IR) and near-infrared (NIR) Raman microspectroscopy techniques for characterization of the composition of growing and developing bone from young to skeletally mature rabbits. Moreover, the specificity and differences of
