In the recent years, there has been an increase in applications of non-contact diffusion optical tomography. Especially when the objective is the recovery of fluorescence targets. The non-contact acquisition systems with the use of a CCD-camera produce much denser sampled boundary data sets than fibre-based systems. When model-based reconstruction methods are used, that rely on the inversion of a
P>Background: Studies of the nasal lavage fluid proteome have previously identified proteins differently expressed in patients with symptomatic allergic rhinitis, e.g. S100A7, prolactin-inducible protein (PIP), wingless-type MMTV integration site family, member 2B (WNT2B), Charcot-Leyden crystal protein (CLC) and palate lung nasal epithelial clone (PLUNC). The aim of the present study was to inves
This questionnaire survey was initiated to acquire information for prepration of a series of field studies. The paper deals with questions that were related to the thermal responses of the feet and footwear performance. The questionnaire was sent to a harbour, a telecommunication company and a customs office. At the harbour most of the workers used footwear with warm lining during winter. Half of
Proteins are composed of 20 different amino acids. In the translation process, each of these 20 amino acids is specifically recognized by their cognate aminoacyl-tRNA synthetase. The fidelity of this recognition system is essential if translation is to function properly. The development of an in vitro system based on this recognition scheme would make a powerful analytical tool with which to analy
We discuss models for ultrawideband propagation channels. In contrast to conventional channels, a UWB channel extends over such a large bandwidth that the propagation conditions for the different frequency components can be markedly different. There is also a much better temporal resolution of multipath components, which leads to a breakdown of the usual assumption of Rayleigh fading. This paper p
A kinetic model describing the enzymatic saccharification of wheat starch by a mixture of ol-amylase and amyloglucosidase has been developed. The model describes the influence of pH, glucose inhibition and starch and enzyme concentration, The results of experimental saccharification under different physical conditions, eg pH and temperature, were used to determine the parameters in the model. The
I focus on the distinction between sensation and perception. Perceptions contain additional information that is useful for interpreting sensations. Following Grush, I propose that emulators can be seen as containing (or creating) hidden variables that generate perceptions from sensations. Such hidden variables could be used to explain further cognitive phenomena, for example, causal reasoning.
The results of three ultra-wideband (UWB) measurement campaigns conducted in two different industrial environments are presented. A frequency range of 3.1 - 10.6 or 3.1 - 5.5 GHz was measured using a vector network analyzer and a virtual array technique enabling the investigation of smallscale statistics. The results show that the energy arrives in clusters, and that the abundance of metallic scat
A new tyre-force model for simultaneous braking and cornering is presented, which is based on combining existing empirical models for pure braking and cornering with brush-model tyre mechanics. The aim is to offer an easy-to-use, accurate model for vehicle-handling simulations. On a working tyre the contact patch between the tyre and the road is, in general, divided into an adhesion region where t
This report is the result of a thesis in mechanical engineering focused on product development. The project was performed at MarineDiesel, a company producing diesel engines for marine applications in Ängelholm, Sweden. A need of a sterndrive strong enough for large diesel engines is present on the market. This thesis involves hydraulic systems and mechanical geometry for trimming and steering of
This report covers the process and result in developing a hand hygiene station for a public environment. With disease spread getting more focus in todays media and society, we wanted to explore and develop a product that is helpful in decreasing the disease spread in our global society. Research was mainly conducted by information gathering from second hand sources, such as scientific- and trend
Denna studie har som syfte att undersöka hur Generation Y, en demografisk grupp som kännetecknas av miljöomtanke, teknologianvändning och resande betraktar den avancerade och multisensoriska kommunikationsformen Virtual Reality (VR) ur ett perspektiv av resande och hållbarhet. Målet är att förstå vilka faktorer som påverkar Generation Y att acceptera och använda VR för resande, samt att undersöka
This thesis is a material science research collaboration between the Division ofProduction and Materials Engineering at Lund Faculty of Engineering and theComputer-Aided Engineerings group at BorgWarner, Landskrona. The objectiveof the thesis is to explore the convertion of nanoindentation load-depth curves intotensile stress-strain curves, and to provide BorgWarner Landskrona with nanoin-dentatio
To move to lower modes in extreme ultra-violet lithography (EUVL) technology (and keep up with Moore’s law), new sources of soft X-ray radiation must be developed. It is clear from previous studies that Free Electron Lasers (FELs) can easily meet the in-band power requirements at these lower wavelength modes, however detailed studies for insertion devices (undulators) as a soft X-ray lithography (
In this study a coarse-grained model of intrinsically disordered proteins (IDPs) is evaluated to determine whether the model is suitable to use for analyzing the structure and dynamics of IDPs. IDPs are proteins that lack a stable tertiary structure which gives them a flexible structure. The aim with this study is to find a model that is appropriate to use for analyzing dynamics events of IDPs. To
We define a mathematical method that, given the form of an interaction network, defines an energy as a function of the state of the network. When combined with a suitable entropy, it yields a free energy that gives rise to the dynamics of the network, allowing solutions and optimal paths to be efficiently found. This is done primarily with the gene regulatory networks governing cell reprogramming
People who make models as their hobbies at home often generate more trash clutters than others. Once they start the modeling process, they often end up having small debris, sanding dust, and spilled paints on their desks. These tiny clutters will reduce their concentration and enthusiasm for the model-building process. It is quite difficult to collect them and get rid of them. Therefore, I design
