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

Benevolent technotopias and hitherto unimaginable meats: Tracing the promises of in vitro meat

Today, in vitro (Latin: in glass) meat researchers strive to overhaul meat production technologies by producing meat outside animal bodies, primarily by culturing cells. In the process, meat should become healthier, more environmentally friendly and kinder to animals. In this article, I scrutinize (and problematize) this promissory discourse by examining the world that proponents envision alongsidToday, in vitro (Latin: in glass) meat researchers strive to overhaul meat production technologies by producing meat outside animal bodies, primarily by culturing cells.

Application-Set Driven Exploration for Custom Processor Architectures

Custom architectures are often adopted as more efficient alternatives to general purpose processors in terms of performance and power. However, the design of such architectures requires experts both in hardware and the application domain. In this paper we propose a method for speeding up the design space exploration. Our method, based on Pareto points, identifies sets of solutions in terms of scal

Human Trafficking and Slavery Reconsidered : Conceptual Limits and States' Positive Obligations in European Law

By reconsidering the international law definitions of human trafficking, slavery, servitude and forced labour, the book demonstrates that in embracing the human trafficking legal framework the international community side-lined the human rights commitments against slavery, servitude and forced labour that in many respects provide better protection for abused migrants. This development urgently req

Urban Radio Access Networks

The increase in demand for high-data rates on the move in the complex urbanenvironment requires either the allocation of new spectrum such as availablecontiguous spectrum in the mm-wave band or the use of novel configurationssuch as the application of massive multiple-input multiple-output (MIMO)technology. To enable the design of efficient wireless networks, an understandingof the propagation phe
