Laser-Based Cancer Diagnostics and Therapy - Tissue Optics considerations.

Near-IR light penetrates deeply into tissue, but as the scattering coefficient is much larger than the absorption coefficient in this wavelength region, direct viewing through tissue is very difficult. In order to detect and locate inhomogeneities located inside tissue a time-resolved technique was developed, based on gated viewing, i.e. detecting the first arriving photons with the shortest path

Urak Lawoi - A Field Study of an Indigenous People in Thailand and their Problems with Rapid Tourist Development

This essay is about Urak Lawoi, an indigenous people in Andaman Sea outside the West Coast of Thailand. The study shows what has happened to them when being deprived of their territory and forced to abandon their culture, lifestyle and traditional economic subsistence. Urak Lawoi have until recently maintained a culture, language and life style set apart from that of the rest of Thai society. Dur

Simple and Causal Twisted-Pair Channel Models for G.fast Systems

The use of a hybrid copper and fiber architecture is attractive in both fixed access and mobile backhauling scenarios. This trend led the industry and academia to start developing the fourth generation broadband system, which aims at achieving bitrates of 1 Gbps over short copper loops. In this context, accurate models of short twisted-pair cables operating at relatively high frequencies are key e

Productive Robots and the SMErobot Project

The need for keeping manufacturing and workplacesin Europe calls for new ideas and concepts for productiverobots with focus on their usefulness for Small andMedium sized Enterprises (SMEs). The activitiesfrom the Robotics Research at LTH, [3], [4], [2], andin particular those related to the SMErobot project[1] comprise efforts in this direction. The SMErobotproject is a recently started four-year-

Energy Management and Control of Electrical Drives in Hybrid Electrical Vehicles

Hybrid vehicles have attracted tremendous attention during the last years. Increasing environmental concern and a steady increase in fuel prices are key factors for the growing interest. Hybrid vehicles, which benefits from having at least two different energy converters and two different energy storage systems, have proven to have significant potential to improve fuel economy without reducing the
