We present new synthetic broad-band photometric colors for late-type giants based on synthetic spectra calculated with the PHOENIX model atmosphere code. The grid covers effective temperatures T-eff = 3000... 5000 K, gravities log g = - 0.5... + 3.5, and metallicities [M/H] = + 0.5... - 4.0. We show that individual broad-band photometric colors are strongly affected by model parameters such as mol
Popular Abstract in Swedish I denna avhandling studeras skolsituationen för elever med båda föräldrarna födda utomlands. Samband mellan elevernas bakgrund, övriga faktorer som i tidigare forskning visat sig betydelsefulla och skolresultat identifieras och analyseras. Studien utgår från de data som insamlades inom ramen för "Det nationella programmet för utvärdering", som genomfördes 1992. UtvärderThe overall purpose of this study was to provide knowledge about the school situation of pupils in Sweden whose parents were both born abroad. The connections between the pupils’ background, other factors shown to be significant in earlier studies, and school results have been identified and analysed. The study was based on the data compiled as part of the National Programme of Evaluation, which w
In the last decades, the growing competitiveness of the market has continuously driven the forming companies to highly optimize their products regarding offered performance at minimum cost. In order to achieve better products, studies where conducted with different material models when simulating the forming process of titanium. The material is often used in heat exchanger applications. Titanium h
This paper presents a fully integrated downlink for low-cost remote antenna units in fiber-fed distributed multi-antenna systems. To reduce the cost of optical parts, an intermediate frequency(IF) signal is distributed over the fiber, and the circuit consists of an optical receiver, a single side-band frequency up-converting radio transmitter, and LO generation circuitry. The optical to electrical
The paper deals with the structure-motion problem for uncalibrated cameras, in the case that subsidiary information is available, consisting, for example, in known coplanarities or parallelities among points in the scene, or known positions of some focal points (hand-eye calibration). Despite unknown camera calibrations, it is shown that in many instances the subsidiary information makes affine or
The use of Intelligent control schemes in Nonlinear Model Based Control (NMBC) has gained widespread popularity. Neural Networks, in particular, have been used extensively to model the dynamics of nonlinear plants. However, in most cases, these models do not lend themselves to easy maneuvering for controller design. Therefore, a common need is being felt to develop intelligent control strategies t
In this Licentiate Dissertation presents a new model for selecting environmental performance indicators in order to improve environmental management. The suggested Total Cost Indicators support a support a preventive approach to environmental management, where environmental issues are addressed before they arise - and before they become costs. The method of selecting indicators builds on earlie
Vehicles in the future are anticipated to have the ability to communicate and exchange useful information in order to avoid collisions. However, for this cooperation to be possible all vehicles will have to be equipped with compatible wireless IEEE 802.11p modules that implement intelligent transport systems operating in the 5 GHz frequency band standard (ITS-G5 or WAVE). During the implementation
Popular Abstract in Swedish De flesta produkter som vi dagligen använder tillverkas genom att utnyttja fossila råvaror som olja, kol och naturgas. Ett stort problem är att dessa råvaror bara finns i begränsade mängder i naturen, vilket medför att de förr eller senare tar slut. Dessutom medför förbränning av fossila råvaror att det bildas miljöskadande gaser (t.ex. koldioxid) som ansamlas i atmosfäOne of the major challenges facing the world today is the reduction of our dependency on fossil resources as their exploitation has severe negative effects on the environment. One way of realizing this is to utilise the components of lignocellulosic biomass to a greater extent as feedstock for various industrial products. However, such utilisation requires the extraction of the biopolymers from th
Artikeln behandlar Svenska Läkaresällskapets engagemang och diskussion kring det tyska folkets nöd efter första världskriget, och i vilken mån sällskapet kunde involvera sig i frågan och i så fall på vilket sätt. Artikeln ställer även frågan om så kallad humanitär verksamhet kan betecknas som "opolitisk" och om inte vetenskapliga organisationer agerar med politiska motiv även om dessa inte deklare
