The role of packaging suppliers in food innovations in Sweden

This study investigated how selected packaging suppliers viewed innovations in food packaging, their role and the roles of other actors in the chain. Six companies and ten respondents were selected based on suggestions from previous interviews of retailers and food manufacturers. Data collection consisted of responses to specific questions followed by responses to open-ended questions. The results

Optimization of a Pendulum System using Optimica and Modelica

In this paper Modelica and Optimica are used to solve two different optimal control problems for a system consisting of a pendulum and a cart. These optimizations will demonstrate that Optimica is easy to use and powerful when optimizing systems with highly non-linear dynamics. The optimal control trajectories are applied to a real pendulum and cart system, in open loop as well as in closed loop w

Hormone Sensitive Lipase - in vitro phosphorylation

Abstract Fatty acids mobilized from triacylglycerol stores are a major energy source in humans. Mobilization occurs through the consecutive action of three lipases: adipose triglyceride lipase (ATGL), hormone-sensitive lipase (HSL) and monoglyceride lipase (MGL). Whereas ATGL and MGL only hydrolyse tri- and monoacylglycerols, respectively, HSL has a broad substrate range and hydrolyses cholesterol

Asynchronous Zipper [subscriber line duplex method]

Previously the authors presented a novel duplex method for very high bit-rate digital subscriber lines (VDSL) called Zipper. With this method all VDSL-modems on different wires in the same bindergroup have to be time-synchronized to avoid near-end cross-talk (NEXT). We describe a method which enables Zipper to run in a time-asynchronous mode. By introducing pulse-shaping in the transmitter and win

Cell signaling: a systems approach

All higher functions of the cell are dependent on cell signaling. It is the way of the cell to obtain information about the world surrounding it. By getting information on e.g. temperature, glucose concentrations, or the density of neighboring cells, the cell can make decisions on how to optimally act given the supplied information. Even though cells are very different, some of the basic mechanism

Characterisation and Some Statistical Aspects of Univariate and Multivariate Generalise d Pareto Distributions

Extreme value theory is about the distributions of very large or very small values in a time series or stochastic process. This has numerous applications connected with environmental science, civil engineering, materials science and insurance. A rather recent approach for modelling extreme events is the so called peak over threshold (POT) method. The generalised Pareto distribution (GPD) is a two-
