A runtime system for implementation of image processing operations is presented. It is designed for working in a flexible and distributed environment related to the software architecture of a newly developed UAV system. The software architecture can be characterized at a coarse scale as a layered system, with a deliberative layer at the top, a reactive layer in the middle, and a processing layer a

Background: Hardwood spent sulfite liquor (HSSL) is a by-product of acid sulfite pulping process that is rich in xylose, a monosaccharide that can be fermented to ethanol by Scheffersomyces stipitis. However, HSSL also contains acetic acid and lignosulfonates that are inhibitory compounds of yeast growth. The main objective of this study was the use of an evolutionary engineering strategy to obtai

The temperature distribution in concrete structures varies due to annual and daily climate variations. Solar radiation, air temperature, wind speed and long-wave radiation affect the temperature in the structure and may cause longitudinal and transversal movements. If these movements are restrained, stresses and strains can be induced which may contribute to cracking. To be able to predict the lon

Banverket äger och förvaltar ett stort antal tunnlar samtidigt som planering och byggande pågår för ett flertal tunnlar. Syftet med föreliggande arbete är att öka kunskapen och på sikt förbättra och förenkla processen angående personsäkerhet i tunnlar. Rapporten beskriver det inventeringsarbete som utförts med avseende på både befintliga och nya tunnlar med fokus på personsäkerhet...

A major component of aircraft noise is the jet noise created by the high velocity hot stream exhausting from a jet engine, interacting with itself and with the surrounding cold air. In the present paper the flow and acoustic fields that are generated by two coaxial jets are considered. Numerically, the problem is divided into a flow related part (Navier-Stokes system of equation) and an acoustic p

The purpose of this paper is to provide an ex-post evaluation of the effectiveness of the South Korean Green New Deal (GND) as an instrument to deliver both an economic recovery and improved environmental performance. We use the energy sector as the main scope for our analysis when measured against climate-related indicators (e.g. CO2 emissions, energy intensity, share of renewable energy in suppl

Finger tapping to isochronous pacing stimuli is a well established experimental paradigm first described in the late 19th century. Two variables of common interest in rhythmic tapping tasks are timing variability and constant error. However, a difficulty when estimating these variables is that at interstimulus intervals longer than 2 seconds participants regularly overshoot the target interval and

The amount of data in large-scale software engineering contexts continues to grow and challenges efficiency of software engineering efforts. At the same time, information related to requirements plays a vital role in the success of software products and projects. To face the current challenges in software engineering information management, software companies need to reconsider the current models

In order to make the hydrogen economy fully sustainable, renewable resources have to be employed for its production. Simulation models, developed with Aspen Plus to calculate mass and energy balances, will be used to integrate the process steps necessary to produce pure hydrogen from biomass in a 2-stage fermentation process. The main challenge is the reduction of water and heat demand connected t

Syftet med denna studie är att utifrån mitt empiriska material kartlägga och beskriva hur föräldrar till barn intagna på 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 av föräldrarna. ”Föräldrar” blir i undersökninThe aim of this study is to analyze how mothers with children placed 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 mothers who were interviewed spoke about some Coordinators that they appreciated. They then pain

Governmental organisations are becoming more critically dependant on IT systems such as communication systems or patient data systems, both for their everyday tasks and their role in crisis relief activities. Therefore it is important for the organisation to analyse the reliability of these systems as part of the organisation’s risk and vulnerability analysis process. This paper presents a practic

A number of approaches for fungicide determination are presented. A surface sampling technique is utilised for the determination of fungicide foliar residues on greenhouse surfaces, mainly leaves. The procedure is based on solvation of the fungicides on the leaf surface with ethanol and HPLC analysis. It was applied to studies of the environment in greenhouses including investigations of decline r

Husserlian phenomenological theory is offered as an integrated and integrating for an understanding of management decision making and related issues in work and organizational sciences. The aspects of meaning, meaning constitution, subjective processes, and perspectives, mutual understanding of each other´s perspective, individuals as horizons of possible worlds are central to this conception, mak

This paper discusses the results of a time-dynamic analysis of the possible effects of government and utility-sponsored energy-efficiency programs on electric energy use in Swedish commercial buildings. In the study, which includes efficient lighting, improvements in ventilation, commercial cooling and cooking, we use energy scenarios to analyse how policy measures can effect future energy demand.

This paper presents a sensitivity analysis of unsteady-state SOFC-GT-HS operation based on two different characteristic maps of centrifugal compressor taken from open literature and scaled by the law of similitude to match the design point of the Hybrid System. The system layout under investigation is a pressurised type comprising a low and high temperature recuperator. Computations are based on a
