During grinding processes, numerous grains interact with the workpiece material producing mechanical and thermal loads on the surface. In the field of thermal simulation of grinding processes, a widely used approach is to substitute numerous cutting edges by a single moving distributed heat source of a specific geometrical shape referring to the theory of Carslaw and Jaeger. This heat source is th

IKEA is a product developing company, known for putting packaging and logistics issues at the top of its agenda. At IKEA, the product and the packaging are developed concurrently with the aim of lowering the total cost from the supplier to the customer. During the years 2002 to 2004, a pckaging redesign project was conducted at IKEA. The purpose of the project was to redesign the packaging for an

Popular Abstract in English Proteins are a class of biological macromolecules that perform countless fundamental and diverse functions in living organisms. Chemically speaking, they are polymers built out of monomeric units called amino acids. All biological proteins are constructed out of 20 different amino-acid types. To form protein molecules, amino acids are linked together in a linear chain lThe minimum free energy state of a protein (the native state) is encoded by its amino-acid sequence. Due to the many torsional degrees of freedom (DOF) available to a polypeptide chain, a vast number of conformations is possible. Therefore, to predict the native state of a protein directly from sequence, a computer algorithm must evaluate a large number of possible conformations using accurate sco

The Swedish Pompeii Project started in 2000 as a research and fieldwork activity initiated by the Swedish Institute in Rome. The aim was to record and analyze an entire Pompeian city-block, Insula V 1. Since autumn 2011 a new branch of advanced digital archaeology, involving 3D reconstructions and documentation methods, was added to the project agenda. The insula was completely digitized using las

Spray drying is a widely used process to produce pharmaceutical powders. In traditional spray drying, the particle size distribution is wide and not well controlled. Using EHD atomization for spray drying offers a possibility to tailor the particle size and morphology. In conventional EHD spray drying, the generated particles are charged and need to be discharged to avoid Rayleigh breakup. Dischar

This paper presents a new framework for solving geometric structure and motion problems based on the L-infinity-norm. Instead of using the common sum-of-squares cost function, that is, the L-2-norm, the model-fitting errors are measured using the L-infinity-norm. Unlike traditional methods based on L-2, our framework allows for the efficient computation of global estimates. We show that a variety

This dissertation provides the first comprehensive account of the prosody of Halh (Khalkha) Mongolian as spoken in Ulaanbaatar, the capital of the Republic of Mongolia. The phonological description is based on acoustic analysis of speech data collected from nine Mongolian-speakers. The dissertation consists of two major parts, the first dealing with rhythmic and the second with tonal properties of

1. Stocking of piscivores in shallow, eutrophicated lakes to reduce cyprinid densities is a common approach in lake restorations. Young-of-the-year (YOY) pike Esox lucius are frequently used to reduce cyprinid densities, but their effectiveness is equivocal. This study uses a simple model to assess the efficacy of pike stocking as a lake restoration tool. 2. The model evaluates YOY pike consumptio

The internal structure of composite gels made of responsive microgel particles inserted into a bulk hydrogel (N-isopropylacrylamide microgel particles in a cross-linked dimethylacrylamide matrix) has been investigated from the diffusion behavior of poly(ethylene glycol) (PEG) probes through the network, in the absence of specific interactions between the diffusing molecules and the system. The eff

We have observed and investigated random telegraph noise in the photoluminescence (PL) from small InP quantum dots (QDs) in GaInP. Very few of the QDs exhibit switching between two states, which have similar total intensities, but distinctly different spectra. Usually, one of the states dominates at low excitation power and the other at high excitation power. The switching occurs on the time scale

Deviances in early event-related potential (ERP) components reXecting auditory and phonological processing are well-documented in children at familial risk for dyslexia. However, little is known about brain responses which index processing in other linguistic domains such as lexicon, semantics and syntax in this group. The present study investigated eVects of lexical-semantic priming in 20- and 24

Much of the progress in astronomy follows imaging with improved resolution. In observing stars, current capabilities are only marginal in beginning to image the disks of a few, although many stars will appear as surface objects for baselines of hundreds of meters. Since atmospheric turbulence makes ground-based phase interferometry challenging for such long baselines, kilometric space telescope cl

We present a batch method for recovering Euclidian camera motion from sparse image data. The main purpose of the algorithm is to recover the motion parameters using as much of the available information and as few computational steps as possible. The algorithm thus places itself in the gap between factorisation schemes, which make use of all available information in the initial recovery step, and s

We propose new applications of three-terminal ballistic junctions (TBJs) in nanoelectronics. It is found that for a TBJ with one of its three branch contacts, say the right branch contact, being grounded, the output voltage, V-c, from the central branch as a function of the voltage, Vl, applied to the left branch shows a diode characteristic: V-c approximately follows Vl linearly when Vl is negati

Wind erosion causes severe damage on sandy soils in agricultural areas of north-west Europe. The weather conditions during erosion events are the result of the general atmospheric circulation and are key components in the erosion process. Principal component analysis (PCA) in combination with a non-hierarchical cluster analysis was conducted on de-seasonalized daily mean-sea-level pressure (MSLP)

In this study a method for the analysis of simultaneous multiple measurements of kinematics and stabilizing forces related to human postural dynamics is proposed. Each subject in a group of normal subjects (n=10) was tested with eyes-open and eyes-closed with simultaneous but uncorrelated vestibular and proprioceptive stimuli in order to investigate the contributions of individual sensory feedback
