Social Work and New Realities in the Swedish Welfare Society

This article argues that there is a discrepancy between the perception of social realities held by professionals of welfare (school teachers and social workers) in Sweden and the social realities of migrants, especially migrants depending on social assistance. The views held by professionals are rooted in an old model of social integration within the framework of the nation-state. This perception

Optimization and Fabrication by 3D Printing of a Volcano Smoke Antenna for UWB Applications

Abstract—Ultra-Wideband (UWB) technology is a low power and high data rate technology for applications like radar imaging, sensor data collection, position localization and medical imaging. In UWB systems, antennas plays a critical role as they are required to be compact and wideband with minimal pulse distortion. This paper present a small three-dimensional volcano smoke antenna, designed and opt

First person perspective, objectivity and language

In the research project The interplay between language and thought in understanding problems from a student perspective, we have analysed students’ understandings of a physical event. The investigation is done from a first person perspective since we are interested in students’ conceptualisations. In discussions about the physical event of throwing a ball, students describe the event in different

Models of a post-combustion absorption unit for simulation, optimization and non-linear model predictive control schemes

An increasing demand on load flexibility in power supply networks is the motivation to look at flexible, and possibly optimal control systems for power plants with carbon capture units. Minimizing the energy demand for carbon dioxide removal under these circumstances reduces the cost disadvantage of carbon capture compared to conventional production. In this work a dynamic model in Modelica of a c

On prediction of tip leakage flow and heat transfer in gas turbines

Abstract in UndeterminedA numerical study has been performed to simulate the tip leakage flow and heat transfer on the first stage of a high-pressure turbine, which represents a modern gas turbine blade geometry. The low Re k-ω (SST) model is used to model the turbulence. Calculations are performed for both a flat and a squealer blade tip for three different tip gap clearances. The computations we
