In their professional practice, designers serve different roles as experts in user behaviour, taste experts and conveyors of symbolic meaning. Combining these roles, however, is not necessarily unproblematic, especially so in contexts that are incongruent with the personal preferences of the designer. In seeking to understand this challenge in designers’ professional practice, it is relevant to hi

In a laboratory study the impact of the surrounding light on alertness was study. Two types oflight sources were examined, LEDs and T5 fluorescent tubes. The illuminance level in theworking area was kept constant (500 lx), while the surrounding light was varied between 100och 350 cd/m2. Subjective ratings of the emotional status and the experience of the lightingenvironment as well as physiologica

Redgörelse för diskussionerna om att eventuellt föreslå en kvinna till lektor i engelska vid Lunds universitet 1890, baserad på originalhandlingar i Lunds universitetsarkiv.

I denna text utgår jag från termen Industrial Cool för att diskutera hur tidigare industriella miljöer får ny dragningskraft. Termen betecknar hur traditionell tillverkningsindustri estetiseras och kulturaliseras på nya sätt. Detta är en följd av att stora delar av industrin i Västvärlden läggs ner eller flyttas till låglöneländer. I takt med att dessa sektorer av industrin blir något som allt fle

In 1949, Swedish actress Ingrid Bergman caused a well known scandal in Hollywood by leaving her Swedish husband Petter Lindström and their daughter for Italian film director Roberto Rossellini. The effects of this scandal in America have been thoroughly described in works like Bergman’s autobiography (Bergman, 1980), Donald Spoto’s recent biography on Bergman (Spoto, 1997) and in specialized schol

In this study, topological structures of a separation bubble in a ribbed channel are identified and analyzed. Particle image velocimetry (PIV) and POD (proper orthogonal decomposition) filter are used to give the velocity vector field. The ribs obstruct the channel by 20% of its height and are arranged 9 rib heights apart. The Reynolds number is 22000 based on the bulk-mean velocity and channel he

Atmospheric aerosol particles affect our living environment in many ways. Their effects are influenced by the interaction between the aerosol particles and the ubiquitous water vapour. The number-size distribution is a primary important parameter for aerosol particles and can be measured using the differential mobility particle sizer (DMPS). Programs have been developed to invert DMPS measurement

An impulse radio transmitter at 60 GHz with pulse duration time down to 100 ps is reported. OOK modulation is presented and the results show promise for other modulation schemes. The transmitter consists of a gated tunnel diode in parallel with a coplanar waveguide, which is a design that provides direct conversion from the baseband pulse train to radio frequency wavelets with a center frequency o

A simple and direct method based on hollow fibresupported liquid membrane (HFSLM) extraction and liquid chromatography equipped with a UV detector was developed for analysis and quantification of parabens in cosmetic products. The parabens analysed included methyl, ethyl, propyl, isobutyl and butyl paraben. The HFSLM extraction was carried out by employing di-n-hexyl ether as organic liquid that w

Popular Abstract in Swedish Proteinvecknings- och proteindesign-problemen studeras med hjälp av modeller med låg upplösning och endast två typer av aminosyror, hydrofoba och hydrofila. Förutom hydrofoba krafter innehåller modellerna sekvensoberoende lokal växelverkan som visar sig ha stor påverkan på termodynamiken hos dessa modeller. Modellerna studeras med hjälp av dynamisk-parameter Monte CarloThe protein folding and protein design problems are addressed, using coarse-grained models with only two types of amino acids, hydrophobic and hydrophilic. In addition to hydrophobicity forces, the models contain sequence-independent local interactions which are found to strongly influence the thermodynamics of these models. The models are studied using the dynamical-parameter Monte Carlo method.

This study is done within the framework of a project aimed at developing a wearable device (a bracelet) intended to support sensory motor rehabilitation of children with visual impairments. We present an exploratory study of aesthetic/hedonistic preferences for sounds and touch experiences among visually impaired children. The work is done in a participatory setting, and we have used mixed methods
