Coming Close? -Techno-Culture and The Longings for Intimacy

How are longings for intimacy engendered in different ways in relation to technology use? How can alternative uses of consumer electronics make us more aware about the conditions for mediation and technology use? The presentation will reflect on a specific consumer electronics product called the Intenso Viddy, which is a cheap video messenger marketed as a lifestyle/mobility-gadget. With it’s inco

Direct Camera Pose Tracking and Mapping With Signed Distance Functions

In many areas, the ability to create accurate 3D models is of great interest, for example, in computer vision, robotics, architecture, and augmented reality. In this paper we show how a textured indoor environment can be reconstructed in 3D using an RGB-D camera. Real-time performance can be achieved using a GPU. We show how the camera pose can be estimated directly using the geometry that we repr

Concrete Roofing Tiles

Good roofing materials are both difficult to find and expensive in developing countries. Roofing tiles using cement as the binding agent have been produced in Europe for over 150 years, and have partially replaced burnt ceramic tiles for purely economic reasons. Although modern factories can produce 10,000 tiles per person per day with a few workers, small-scale hand production still offers both g

Debris-free Laser-plasma Soft X-Ray Source for Microscopy.

This thesis describes the initial development of a new high-brightness table-top soft X-ray source suitable for microscopy. The laser-plasma utilises liquid droplets as targets and the absolute line emission in the water window (A-=2.3-4.4 nm) is typically 1·1012 photons/(stedine·pulse). The narrow bandwidth radiation makes the source suitable for zone plate optics used in microscopy. Compared to

Decision Support for Extreme Programming Introduction and Practice Selection

This paper presents an investigation concerning the introduction of Extreme Programming (XP) in software development organisations. More specifically the concept of using a decision support method known as the Analytical Hierarchy Process (AHP) is evaluated by a group of students and a group of developers and the outcome is compared to experiences from an XP case study. The results provide an indi

Use of couple-stress theory in elasto-plasticity

One way to avoid vanishing dissipative energy and localization to zero volume when examining localization and softening problems, is to introduce an internal length scale for the material by means of couple-stress theory. Here, the ‘constrained’ Cosserat theory is adopted where the displacement field also determines the rotation field. For this ‘constrained’ Cosserat theory an elasto-plastic theor
