New products on the market are likely to be simulated in a computer sometime during the development process. The environment for which the physical model of the product is developed may not always be the optimal for control simulations of the model. To be able to export models from one environment to another a common model definition must be defined. The Functional Mock-up Interface, FMI, provides
The origin of many environmental and health hazardous emissions from diesel engines are the crankcase gases. Since no regulations of the emission levels from the crankcase have existed in the past, no attention has been paid to cleaning crankcase gases. New regulations are coming up and they will all demand lower emissions from the engine. This has lead to the introduction of the Alfdex separator.
The aim of this Master Thesis was to measure and quantify the effect of a continuous visual stimulus on postural stability. The visual stimulus was applied using a Head Mounted Display through which the image of a vertically rotating cylinder was projected. It was hoped that the relationship between the speed of rotation of the cylinder and the body sway of the subject would be quantified through
This paper empirically investigates the relationship between product market competition and innovation in seven European countries for the period 1987-2006. To approximate change in competition level three measures are considered: mark-up level, import penetration and the number of firms on the market. Innovation is measured as R&D intensity. The analysis shows that effect of product market co
The study will be focusing specifically on the impacts that these entrepreneurs have had on the UK (regional) economy. In the last 20 years we have seen a wealth of studies analyzing the determinants of entrepreneurship. Though some of these studies are theoretical (e.g. Holmes and Schmitz, 1990), others are empirical (e.g. Evans and Leighton, 1990). The impacts of entrepreneurship, in terms of ec
The goal with this master thesis is to examine the usability in the Tetra PlantMaster. Tetra PlantMaster is the control system for the dairies that Tetra Pak develops. Tetra PlantMaster is the system which the operator uses in order to govern the entire process when raw milk becomes a product ready to be delivered to the grocery stores. This includes applications to produce soured milk, yoghurt, i
The study raises the question how (if at all) relations with university affect the innovativeness of new media firms in Skåne and to what extent it can be related to the type of knowledge base. The object of the analysis is 36 new media companies in the region. The data was selected using the methods of structured and semi-structured interviews. Open Innovation paradigm, knowledge base and knowled
This study investigates how the debt levels of firms belonging to the Nordic market change over time and what determines these changes. We find that contemporaneous changes in leverage are mainly determined by profitability, market timing, leverage deficits (deviations from target leverage) and changes in targets. We find two factors whose effects persist for at least ten years, namely profitabili
In recent years, business process management (BPM) is a vital methodology or strategy to drive business management agilely. It is an approach that can make the organization achieve effectiveness and efficiencies through creating and ameliorating its business processes according to its business strategies, objectives, and requirements. There is no doubt that dynamic and flexible business processes
The purpose of this thesis is to test the implications of the permanent income – life cycle hypothesis. According to Hall (1978), if the permanent income-life cycle hypothesis is valid, consumption should follow a random walk and no variable other than once-lagged consumption should help explaining current consumption. Two different tests are conducted. Firstly, consumption is regressed upon its o
Extended shelf-life milk can be produced by a combination of microfiltration and pasteurisation. However, due to the need for high cross-flow velocity during microfiltration, the energy consumption is high. One way of decreasing the energy demand during microfiltration is to use back-pulsing for fouling control. Microfiltration was performed in constant flux mode on skim milk to measure the foulin
This study reports increasing iron concentrations in rivers draining into the Baltic Sea. Given the decisive role of iron to the structure and biogeochemical function of aquatic ecosystems, this trend is likely one with far reaching consequences to the receiving system. What those consequences may be depends on the fate of the iron in estuarine mixing. We here assess the stability of riverine iron
Motivated by the recent discovery of a canyon of conductance suppression in a two-level equal-spin quantum dot system [Phys. Rev. Lett. 104, 186804 (2010)], the transport through this system is studied in detail. At low bias and low temperature a strong current suppression is found around the electron-hole symmetry point independent of the couplings, in agreement with previous results. By means of
Background: Medial temporal lobe atrophy (MTA) is an early sign of Alzheimer's disease (AD). The current method of choice for measuring MTA is volumetric measurement based on 3D magnetic resonance imaging (MRI), but this complicated method has not been implemented clinically. Purpose: To investigate whether simple computed tomography (CT) linear measurements of the brain could be of value in AD wo
Context. New instrumental capabilities and the wealth of astrophysical information extractable from the near-infrared wavelength region have led to a growing interest in the field of high resolution spectroscopy at 1-5 mu m. Aims. We aim to provide a library of observed high-resolution and high signal-to-noise-ratio near-infrared spectra of stars of various types throughout the Hertzsprung-Russell
Two-dimensional spectroscopy has recently revealed the oscillatory behavior of the excitation dynamics of molecular systems. However, in the majority of cases there is considerable debate over what is actually being observed: excitonic or vibrational wavepacket motion or evidence of quantum transport. In this letter we present a method for distinguishing between vibrational and excitonic wavepacke
Mn5Ge3(001) thin films grown on Ge(111) were studied by angle-and spin-resolved photoemission using synchrotron radiation in the 17-40 eV photon energy range. The photoelectron spectra were simulated starting from a first-principles band-structure calculation for the ground state, using the free-electron approximation for the final states, taking into account photohole lifetime effects and k(perpe
Parents influence the development of their offspring in many ways beyond the transmission of DNA. This includes transfer of epigenetic states, nutrients, antibodies and hormones, and behavioural interactions after birth. While the evolutionary consequences of such non-genetic inheritance are increasingly well understood, less is known about how inheritance mechanisms evolve. Here, we present a sim
In this paper, a numerical experiment, consisting of 90 simulations in Fire Dynamics Simulator (FDS), is conducted for two different purposes. Firstly, numerical experiments are explored as a research method in fire science, and it is demonstrated that numerical experiments could be used as a complement to traditional fire experiments in fire science research. Secondly, an evaluation of previously
