The Effect of Signaling Rate on Information Rate for Single Carrier Linear Transmission Systems

We consider the effect of signaling rate (baud rate) on the information rate of single carrier linear transmission systems with Gaussian inputs. Several different communication scenarios are investigated: correlated or uncorrelated symbols, a fixed modulation pulse or a modulation pulse varying with the signaling rate and frequency selective or flat channels. For uncorrelated symbols, we show that

"Kärlek mötte mig i varje stycke" : mission och materialitet i det humanitära arbetet bland armeniska flyktingar i Thessaloniki, 1923-1947

In this article I discuss how material things can function as a key to a wider understanding of the mission enterprise. From the example of the Swedish missionary Alma Johansson, who worked among Armenian refugees in Thessaloniki, 1923–1947, I analyze the role of needlework in the humanitarian work and show how exchanges of needlework over the borders created cosmopolitan bonds of solidarity betwe

The PREDICTS database: a global database of how local terrestrial biodiversity responds to human impacts.

Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species' threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a rang

Endogenous Dynamics of Institutional Change

A parsimonious set of mechanisms explains how and under which conditions behavioral deviations build into cascades that reshape institutional frameworks from the bottom up, even if institutional innovations initially conflict with the legally codified rules of the game. Specifically, we argue that this type of endogenous institutional change emerges from an interplay between three factors: the uti

In Situ Characterization of Nanowire Dimensions and Growth Dynamics by Optical Reflectance

Optical reflectometry is commonly used as an accurate and noninvasive characterization tool when growing planar semiconductor layers. However, thin-film analysis schemes cannot be directly applied to nanowire systems due to their complex optical response. Here, we report on reliable in situ characterization of nanowire growth with high accuracy using optical reflectance spectra for analysis. The m

An investigation of Cu(II) and Ni(II)-catalysed hydrolysis of (di)imines

The reactions of six diimine ligands with Cu(II) and Ni(II) halide salts have been investigated. The diimine ligands were Ph2C=N(CH2)(n)NC=Ph-2 (n = 2 (Bz(2)en, 1a), 3 (Bz(2)pn, 1b), 4 (Bz2bn, 1c)), N, N'-bis-(2-tert-butylthio- 1-ylmethylenebenzene)-2,2'diamino-biphenyl (2), N,N'-bis-(2-chloro-1-ylmethylenebenzene)-1,3diaminobenzene (3) and N,N'-bis-(2-chloro-1-ylmethylenebenzene)-1,2-ethanediamin

Chyliza leguminicola Melander, 1920 (Diptera: Psilidae) new to the Palaearctic fauna.

The Nearctic species Chyliza leguminicola Melander, 1920 has been found breeding in Denmark. It is reported here for the first time in the Palaearctic region. The first known Danish record is from 1991, and the species is well established at least in the eastern part of Jutland. Data on the distribution as currently known is presented. It is possible that C. leguminicola is actually established bu

Introduction

Our continuously changing global environment requires continuous and detailed monitoring for us to understand how ecosystems are structured and function in response to climatic changes. Understanding the arctic ecosystems is of particular importance (Oechel et al., 1997). Indeed, rather than in boreal and temperate regions, the forecasted climatic changes will be first and most pronounced in the A

Pseudomonas aeruginosa Uses Dihydrolipoamide Dehydrogenase (Lpd) to Bind to the Human Terminal Pathway Regulators Vitronectin and Clusterin to Inhibit Terminal Pathway Complement Attack.

The opportunistic human pathogen Pseudomonas aeruginosa controls host innate immune and complement attack. Here we identify Dihydrolipoamide dehydrogenase (Lpd), a 57 kDa moonlighting protein, as the first P. aeruginosa protein that binds the two human terminal pathway inhibitors vitronectin and clusterin. Both human regulators when bound to the bacterium inhibited effector function of the termina

Production of pi/K/p from intermediate to high p(T) in pp, p-Pb and Pb-Pb collisions measured by ALICE

In this work the results on the transverse momentum distributions (similar to 0.3 < p(T) < 15 GeV/c) of charged pions, kaons and (anti)protons, measured in pp and Pb-Pb collisions at root S-NN = 2.76 TeV and in p-Pb collisions at root S-NN = 5.02 TeV, presented. The evolution of the spectral shapes and particle ratios with multiplicity is shown and the similarities among the different systems are

Pushed into Unemployment, Pulled into Retirement: Facing Old Age in Gothenburg, 1923-1943

Along with rapid growth and improved standards of living, the first decades of the twentieth century saw the introduction of new technology and new ways to organize production. There are contrasting views on what impact these developments, often summarized as the Second Industrial Revolution, had on the situation of old men in the labour market. Some contemporary observers and modern-day historian

Planar Motion and Visual Odometry: Pose Estimation from Homographies

This thesis concerns ego-motion and pose estimation of a single camera under the assumptions of planar motion and constant internal camera parameters. Planar motion is common for cameras mounted onto mobile robots, particularly in indoor scenarios, as they remain at a constant height above the ground plane. In Paper A, a parametrisation of the camera motion and pose is presented, along with an ite

On Aniridia in Sweden and Norway

Introduction Aniridia (iris more or less missing), is a congenital, dominant, inherited, serious and sight-threatening disease, most often appearing as an isolated eye disorder. It is caused by mutations in the PAX6 gene, the master gene of the development of the eye. Typically, Aniridia causes severe visual impairment. In addition to glare caused by the iris defect, underdevelopment of the macula

Abstract in Danish I den vestlige del af Limfjorden findes en række kystklinter, hvor eocæne lag er blottet. Moler er en ca. 55-56 millioner år gammel diatomit, som indeholder lag af uforvitret vulkansk aske samt et stort antal velbevarede marine og terrestriske fossiler. Stolleklint Leret og Fur Formationen har et usædvanligt fossilselskab med mange repræsentanter for insekter, fisk, fugle og ski

Drought, death and the sun in Ugarit and ancient Israel : A philological and comparative study

The sun and its heat are two of the most universal symbols known to humanity, yet their supposed meanings vary greatly. The sun can be thought of as a giver of life, but its hot and scorching rays can also be associated with drought and the powers of destruction. The present study concerns the latter view of the sun and related ideas as reflected in the Hebrew Bible and the cuneiform alphabetic te

Projektet utifrån institutionspersonalens perspektiv

Syftet med denna studie är att utifrån mitt empiriska material kartlägga och beskriva hur de anställda på de särskilda ungdomshemmen tolkar, definierar, och upplever ett behandlingsprojekt, som involverade olika myndigheter, benämnt Motverka Våld och Gäng. Dessutom uppmärksammas hur de anställda samordnarna uppfattades och kategoriserades. I institutionspersonalens framställning är samordnarens The aim of this study is to map out and describe the way employees in Swedish juvenile homes interpret, define and perceive, on the one hand, the project “Motverka Våld och Gäng” meaning “Counteract Violence and Gangs”, and on the other hand the role of the Coordinators employed in this project. The role of the Coordinator is formally clear and unproblematic. The project management directives sta

Housing Accessibility Methodology Targeting Older Poeple - Reliable Assessments and Valid Standards

Older people have more functional limitations than younger people and they form a segment of the population that is more dependent on mobility devices than other age groups. Since they spend most of their time at home, their dwelling is an important environmental arena for performing everyday activities. Barriers in the environment can limit or hinder activity performance. Therefore, older people
