A number of techniques have been proposed to provide run- time performance guarantees while minimizing power consumption. One drawback of existing approaches is that they work only on a fixed set of components (or actuators) that must be specified at design time. If new components become available, these management systems must be redesigned and reimplemented. In this paper, we propose PTRADE, a n

There are many reasons why heat transfer and heat exchangers play a key role in the development of sustainable energy systems as well as in the reduction of emissions and pollutants. In general, all attempts to achieve processes and thermodynamic cycles with high efficiency, low emissions, low costs include heat transfer and heat exchangers to a large extent. It is known that sustainable energy de

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

Carrier frequency offset (CFO) synchronization is a crucial issue in the implementation of orthogonal frequency division multiplexing (OFDM) systems. Since current technology tends to implement different standards in the same wireless device, a common frequency synchronization structure is desirable. Knowledge of the physical frame and performance and cost system requirements are needed to choose

This paper introduces a two-dimensional extension of the well established Rietveld refinement method for modeling neutron time-of-flight powder diffraction data. The novel approach takes into account the variation of two parameters, diffraction angle 2θ and wavelength λ, to optimally adapt to the varying resolution function in diffraction experiments. By doing so, the refinement against angular- a

BACKGROUND: The objective of this study was to assess, in a large data set from Swedish Medical Health Registries, whether maternal obesity and maternal morbid obesity were associated with an increased risk for various structural birth defects. METHODS: The study population consisted of 1,049,582 infants born in Sweden from January 1, 1995, through December 31, 2007, with known maternal weight and

Childhood and adolescence are critical periods of neural development and physical growth. The malnutrition and related medical complications resulting from eating disorders such as anorexia nervosa (AN), bulimia nervosa (BN) and eating disorder not otherwise specified may have more severe and potentially more protracted consequences during youth than during other age periods. The consensus opinion

Under de senaste åren har stora resurser lagts på forskning kring utvecklingen av biomaterial för ersättning av fossil-baserade material. Förpackningsindustrin i synnerhet är en sektor känd för att generera enorma mängder fast avfall, med produkter som inte sällan har betydligt kortare livslängd än sina materialkomponenter. Polylaktid (PLA) är en mångsidig biopolymer som används kommersiellt föIn recent years, large efforts have been put into the research of biomaterial synthesis for the replacement of fossil-based materials. Particularly in the packaging industry, a sector responsible for generating enormous amount of solid waste in which products have a considerably shorter life span than their material components. Polylactic acid (PLA) is a versatile, commercial biopolymer used fo

Industrial pasteurisation is a heat-intensive process with significant potential for decarbonisation. This study investigates how open-source Modelica libraries can be adapted for industry, especially for food industry, and integrated to replace fossil-based thermal systems. Investigations are done to evaluate models of heat pumps, thermal energy storage, specifically the stratified tank, and sol

Network cameras observe physical spaces but lack an inherent understanding of the scenes they see. This thesis presents a pipeline for floor and wall instance segmentation from a single uncalibrated RGB image, requiring no scene-specific prior information such as camera intrinsics, depth sensors, floor plans, or labelled floor and wall data for training. The detected instances are intended to supp

Electronic Image Stabilization is a method to digitally stabilize a video feed to remove unwanted motion by transforming the image. The aim is to create a better viewing experience, reduce bitrate, and simplify further video analytics. This thesis explores different algorithms to stabilize Pan-Tilt-Zoom surveillance cameras made by Axis Communications. Many scenarios are investigated, but the case

Förarapplikationer används i allt större utsträckning hos yrkesförare för att stödja företags ruttplanering, orderhantering, dokumentation och intern/extern kommunikation. När förare behöver läsa, tolka och/eller interagera med information i situationer kopplade till körning kan dessa system även skapa visuell, manuell och kognitiv distraktion, vilket ökar risken för trafikrelaterade skador. DettaDriver applications are increasingly used in professional driving to support route planning, order management, documentation, and communication. When drivers need to read, interpret, or interact with information in close proximity to driving, these systems can also create visual, manual, and cognitive distractions, increasing traffic safety risk. This master's thesis was conducted in collabora

Importance: Accurate risk prediction of morbidity and mortality in patients with heart failure with preserved ejection fraction (HFpEF) may help clinicians risk stratify and inform care decisions. Objective: To develop and validate a novel prediction model for clinical outcomes in patients with HFpEF using routinely collected variables and to compare it with a biomarker-driven approach. Design, Se

Music therapy is a “vocally demanding profession” [1, p. 46]. Currently, little is known about the prevalence and about the possible risk factors for voice disorders within music therapy. As music therapy workspaces may not always be ideal in terms of acoustics, the aim of the study is to investigate room acoustics and noise as risk factors for possible voice disorders among music therapists in Fi
