Despite morphological divergence, the two orchid genera Gymnadenia andNigritella are closely related and hybrids are often encountered at places wheremembers of the two genera grow together. On basis of pollination studies, it hasbeen suggested that members of Nigritella should have served as pollen parent tothese hybrids. Hybridization does not go beyond primary hybrid formation, butone of the hy
Diamond-Blackfan anemia (DBA) is a rare congenital disease where the patients suffer from macrocytic anemia due to reduced numbers of erythroid precursors in the bone marrow. Most patients carry mutations in ribosomal proteins, such as ribosomal protein S19 (RPS19), which causes deficient ribosome biogenesis and affects protein translation. Ribosomal protein mutations also cause increased apoptosi
The modelling of large systems is greatly simplified if their hierarchical decomposition and interconnection structure can be described graphically. The paper describes a system allowing input of block diagrams and continuous zooming to view internal details. Model equations are automatically transformed to assignment statements when possible, allowing efficient explicit integration routines to be
Modern antenna design for communication systems revolves around two extremes: devices, where only a small region is dedicated to antenna design, and base stations, where design space is not shared with other components. Both imply different restrictions on what performance is realizable. In this paper properties of both ends of the spectrum in terms of MIMO performance is investigated. For small a
Background: Numerous different types of variations can occur in DNA and have diverse effects and consequences. The Variation Ontology (VariO) was developed for systematic descriptions of variations and their effects at DNA, RNA and protein levels. Results: VariO use and terms for DNA variations are described in depth. VariO provides systematic names for variation types and detailed descriptions fo
This master thesis present a simulation environment developed in Matlab/Simulink, which can be used for control design and code generation for real-time control experiments for the Gantry-Tau parallel robot. The Gantry-Tau is a new parallel robot concept which offers great rigidity, high speeds and large workspace. The kinematics library presented in this thesis is developed for the 5 degrees of f
Every car has its own cornering dynamics, some are oversteered, meaning that they respond more to a steering input, and some are understeered, responding less to a steering input. These dynamics depend on a wide range of parameters, the size and weight of a car and the distribution of the weight to name a few. The main part of this thesis is aimed at controlling the cornering dynamics. More specif
When using industrial robots in production lines both speed and accuracy is of great importance. This thesis investigates how off-line optimization can be used to create references to a control structure with the aim of traversing a given path in as little time as possible, under given input constraints, without deviating from the path. In this thesis Modelica and Optimica is used to formulate and
In patients unsuitable for standard, infrarenal endovascular aneurysm repair (EVAR) due to an inadequate or inappropriate infrarenal neck, various options have been proposed to achieve a suitable endovascular repair. The primary objective in this setting is to move the endograft sealing zone to a healthier, more cranial segment of the aorta. The need for a solution for problematic proximal neck an
The robust Capon beamformer has been shown to alleviate the problem of signal cancellation resulting from steering vector errors, caused, e.g., by calibration and/or angle- of-arrival errors, which would otherwise seriously deteriorate the performance of an adaptive beamformer. Here, we examine robust Capon beamforming of multi-dimensional arrays, where robustness to angle-of-arrival errors is nee
We examine consumer certainty of future preferences and overconfidence in predicting future preferences. We explore how preference certainty and overconfidence impact the option value to revise today's decisions in the future. We design a laboratory experiment that creates a controlled choice environment, in which a subject's choice set (over food snacks) is known and constant over time, and the t
Complex formation between [Pd(H2O)(4)](2+) and oxalate (ox = C2O42-) has been studied spectrophotometrically in aqueous solution at variable temperature, ionic strength and pH. Thermodynamic parameters at 298.2 K and 1.00 mol dm(-3) HCIO4 ionic medium for the complex formation [Pd(H2O)(4)](2+) + H(2)ox (sic) Pd(H2O)(2)(ox)] + 2H(3)O(+) with equilibrium constant K-1H (in mol dm(-3)) are logio K-1,K
Popular Abstract in Swedish Idag kan vi mäta mycket låga halter av gifter i t. ex. dricksvatten och livsmedel, bland annat genom utvecklingen av nanosensorer. Sensorerna kan också använda's medicinskt, t. ex för att väsentligt underlätta livet för diabetiker. Idag drabba's diabetespatienter ofta av nedsatt känsel i fingrarna på grund av dagliga nålstick. Med hjälp av de nya sensorerna kan vi nu mäA new type of Bioelectronic Nanosensor Device with potential applications in medicine,biotechnology and environmental analysis was designed. The nanosensor is based on RISFET (Regional Ion Sensitive Field Effect Transistor) technology. The design of the nanosensor involves use of a set of nano-sized electrodes on the surface of a silicon chip, giving the chip the ability to sense extremely low con
Popular Abstract in Swedish Arbetet har bestått av att dels experimentellt samt dels med hjälp av matematiska modeller undersöka och kartlägga förloppen för nya samt "gamla" metoder att rena rökgaser från kol- och olje eldade kraftverk.Combustion of fossil fuels is the main source for emissions of sulfur dioxide and nitrogen oxides. Emission regulations and the growing environmental awareness will make great demands upon cost-effective deSO2 and deNOx techniques in the future. Many of the techniques available today have been on the market for a long time, however, most of them still have a potential for improvement. To be able t
