This report describes a method to estimate the video bandwidth for IP cameras using the H.264 standard. The precise determination of bandwidth allows us to model the network access as a scheduling problem and/or estimate the amount of data that would traverse it during different periods. The paper is written to be as didactic as possible and presents a set of experiments, conducted in an industria
Hydropower is a major energy source in Sweden and proper reservoir management prior to the spring flood onset is crucial for optimal production. This requires useful forecasts of the accumulated discharge in the spring flood period (i.e. the spring-flood volume, SFV). Today's SFV forecasts are generated using a model-based climatological ensemble approach, where time series of precipitation and te
This article takes stock of recent changes to Sweden’s immigration policy and draws upon statistical data to show the effect of the new immigration regime. It discusses the structural economic challenge of integrating immigrants who lack education and job training, and offers Sweden as a reference (or perhaps cautionary tale) for other coun- tries seeking to change their immigration policies. This
Objectives: Transfusion-related acute lung injury is characterized by the onset of respiratory distress and acute lung injury following blood transfusion, but its pathogenesis remains poorly understood. Generally, a two-hit model is presumed to underlie transfusion-related acute lung injury with the first hit being risk factors present in the transfused patient (such as inflammation), whereas the
Syftet med detta forskningsprojekt är att i samverkan med räddningstjänster, kommuner och andra berörda aktörer i storstadsområden, analysera bakomliggande bestämningsfaktorer till rumsliga, bebyggelse - och befolkningsmässiga skillnader i förekomsten av bostadsbränder. Projektet ska genom samproduktion med berörda aktörer utveckla förslag på hur brandsäkerhetsarbetet kan bedrivas och utvärderas i
'Adaptive Landscape' was first formulated as a heuristic model or metaphor for the evolutionary process by late population geneticist Sewall Wright in a famous paper published in 1932. The metaphor of an adaptive landscape with adaptive peaks of high fitness, separated by adaptive valleys of low fitness attracted a lot of interest from contemporary and later evolutionary biologists and inspired re
Map mashups, as a common way of presenting geospatial information on the Web, are generally created by spatially overlaying thematic information on top of various base maps. This simple overlay approach often raises geometric deficiencies due to geometric uncertainties in the data. This issue is particularly apparent in a multi-scale context because the thematic data seldom have synchronised level
Den första januari 2012 sänkte den då sittande alliansregeringen momssatsen för restaurang- och cateringtjänster från 25 % till 12 %. Det övergripande målet med den lägre momssatsen är att stimulera efterfrågan på okvalificerad arbetskraft genom att skapa förutsättningar för lägre priser och därmed ökad efterfrågan på restaurangföretagens tjänster.Under tiden efter genomförandet av den sänkta momsA significant part of the labour market debate is devoted to issues concerning problematic youth. Expressions like “the lost generation” is coined to address the very core of the matter. It captures the difficulties for low-skilled young people to gain a sustainable work life in an education-oriented society. A strategy to increase employment opportunities specifically suited for the latter group
A new and freely available model-based PID design tool for Matlab is introduced. It can be used to solve Maximal Integral Gain Optimization (MIGO) and (load) Integral Absolute Error (IAE) problems. Robustness is ensured through H-inf constraints on the closed-loop transfer functions. A Youla parameter (Q design) method for comparison with the optimal linear time-invariant (LTI) controller for the
Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease. Anti-citrullinated protein antibodies (ACPA) are crucial for the serological diagnosis of RA, where Epstein-Barr virus (EBV) has been suggested to be an environmental agent in triggering the onset of the disease. This study aimed to analyse antibody reactivity to citrullinated EBV nuclear antigen-2 (EBNA-2) peptides from three dif
Microcapsules with specific functional properties, related to the capsule wall and core, are highly desired in a number of applications. In this study, hybrid cellulose microcapsules (1.2 ± 0.4 μm in diameter) were prepared by nanoengineering the outer walls of precursor capsules. Depending on the preparation route, capsules with different surface roughness (raspberry or broccoli-like), and thereb
Substantial evidence now supports the hypothesis that the common ancestor of bats was nocturnal and capable of both powered flight and laryngeal echolocation. This scenario entails a parallel sensory and biomechanical transition from a nonvolant, vision-reliant mammal to one capable of sonar and flight. Here we consider anatomical constraints and opportunities that led to a sonar rather than visio
In this paper, I consider the question of whether crime victims can be said to have a moral right to see their victimizers punished (a “right to punishment”) that could explain why they often feel wronged or cheated when the state fails to punish offenders (or even to make such conduct punishable). In the first part, I explain what I mean by a “right to punishment” and what it is for such a right
