A flexible runtime system for image processing in a distributed computational environment for an unmanned aerial vehicle

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

Adaptation of Scheffersomyces stipitis to hardwood spent sulfite liquor by evolutionary engineering

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

Integration study on a two-stage fermentation process for the production of biohydrogen

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

Maskinisk darwinism: teknikens naturhistoria hos Samuel Butler och Gilles Deleuze

This paper provides perspectives on the development of an idea of the machine as a living being in the 20th century by looking at the relationship between the writings of Samuel Butler and Gilles Deleuze concerning the evolution of machines as an extension of—and in competition with—the human organism. Ultimately, Butler and Deleuze both describe a mechanical or “machinic" vitalism and evolutionis

Stable Peptide of the Endogenous Opioid Enkephalin Precursor and Breast Cancer Risk.

In experimental studies, enkephalins (ENKs) and related opioids have been implicated as negative regulators of breast cancer development by enhancing immune-mediated tumoral defense as well as directly inhibiting cancer cells. We hypothesized that plasma levels of ENKs are predictive of the long-term breast cancer risk. Therefore, our objective was to measure pro-ENK A, a surrogate for mature ENK,

Estimation of Extreme Climatic Thermal Actions in Concrete Structures

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

Flow and noise investigations of a separate flow exhaust system

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

Assessing the effectiveness of the ‘Green Economic Stimulus’ in South Korea: Evidence from the energy sector

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

Separating predictive responses from reactive responses in isochronous finger tapping using Bayesian hierarchical modeling

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

Towards scalable information modeling of requirements architectures

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

Risk Analysis for Critical Systems with Reliability Block Diagrams

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

Surface Sampling and Automated Liquid Membrane Extraction of Fungicides

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

Defective paracrine signalling by TGF beta in yolk sac vasculature of endoglin mutant mice: a paradigm for hereditary haemorrhagic telangiectasia

Hereditary haemorrhagic telangiectasia (HHT) is an autosomal dominant disorder in humans that is characterised by multisystemic vascular dyplasia and recurrent haemorrhage. Germline mutations in one of two different genes, endoglin or ALK1 can cause HHT. Both are members of the transforming growth factor (TGF) beta receptor family of proteins, and are expressed primarily on the surface of endothel

Compliance with the WHO Surgical Safety Checklist: deviations and possible improvements.

BACKGROUND: /st>Previous research suggests that the World Health Organization Surgical Safety Checklist time-out reduces communication failures and medical complications and supports development of better safety attitudes. Previous research also indicates that different values can affect the implementation of interventions. OBJECTIVE: /st>To investigate the actual usage of the checklist in practic
