Quantitative analysis of circadian variation in atrial fibrillation frequency
Circadian variation in atrial fibrillation (AF) frequency is explored in this paper by employing recent advances in signal processing. Once the AF frequency has been estimated and tracked by a hidden Markov model approach, the resulting trend is analyzed for the purpose of detecting and characterizing the presence of circadian variation. With cosinor analysis, the results show that the shortterm v

The ethanol-water humidification process in Evgt cycles
Ethanol from bio-products has become an important fuel for future power production. However, the present production technology is rather expensive. This paper focuses on how to lower the production cost of ethanol extraction from mash, and to use the ethanol as a primary fuel in gas turbines for heat and power production. Today, ethanol is produced during distillation by supplying energy to extrac

Addressing resource efficiency through the Ecodesign Directive: a review of opportunities and barriers
The European Union has initiated a number of initiatives to improve resource efficiency in Europe. The Ecodesign Directive is one of the policy instruments that could aid the transition towards a more resource efficient economy. So far, the Directive has mainly been applied to set requirements related to energy efficiency, but there is potential for setting legal standards that increase product du
Dynamic Modelling and Simulation of Liquid Food Process Lines
Popular Abstract in Swedish I följande arbete har ett dynamiskt modellbibliotek av komponenter utvecklats för processlinjer. Analysen inriktades mot karakteristiska aspekter för processlinjer för flytande livsmedel, och nya modeller utvecklades för byte av fluidum, dispersion, blandfaser och första ordningens kemiska reaktioner i rör och värmeväxlare. Modellernas beräkningseffektivitet och noggranIn the present work a dynamic model library of components for process lines was developed. The analysis addressed characteristic aspects of liquid food process lines, and new models were developed for fluid transitions, dispersion, mixing zones and first-order chemical reactions in pipes and heat exchangers. The computational efficiency and accuracy of the models were analysed. It was demonstrated

Automatic Grid Control in Adaptive BVP Solvers
Modern adaptive techniques in two-point boundary value problems generate the mesh by constructing a function that maps a uniform grid to the desired nonuniform grid. This paper describes a new control algorithm for constructing a grid density function $phi(x)$, such that the local mesh width $Delta x_{j+1/2}=x_{j+1}-x_j$ is computed as $Delta x_{j+1/2} = varepsilon_N / varphi_{j+1/2}$. Here $varep
