Evaluation of some integrals relevant to multiple scattering by randomly distributed obstacles
This paper analyzes and solves an integral and its indefinite Fourier transform of importance in multiple scattering problems of randomly distributed scatterers. The integrand contains a radiating spherical wave, and the two-dimensional domain of integration excludes a circular region of varying size. A solution of the integral in terms of radiating spherical waves is demonstrated. The method empl

Improvement in Time-domain IP Data Quality with Multi-electrode Systems by Separating Current and Potential Cables
Good quality time-domain IP data can be obtained using multi-electrode resistivity-IP equipment and standard electrode cable layouts at sites with favourable electrode contact. High contact resistances often result in low signal levels and capacitive coupling problems making the IP signals drown in noise. We tested an approach for measuring with separated cable spreads for current transmission and

Evolutionism har mörk historia
Sekularister använder gärna Darwin som slagträ mot meningsmotståndare med en religiös värdegrund. Men evolutionismens vetenskapshistoria är allt annat än ljus och dess förklaringsvärde ytterst begränsat vid analyser av kulturer och samhällen, skriver religionsantropologen Pierre Wiktorin vid Lunds universitet i ett svar till Birgitta Forsman (Aktuella frågor 11/2-2009).

Turning older people’s experiences into innovations: ippi as the convergence of mobile services and TV viewing
This paper presents the results of a research project in which a patented system for asynchronous communication (“ippi”) is used as the basis for a prototype communication device utilizing the participants’ televisions as the primary interface. The aim was to study the extent to which older people’s lifelong experiences watching TV reduced their uncertainty when faced with TV-based applications. T

Domain decomposition in acoustic and structure–acoustic analysis
Finite element analysis in acoustics, structure–acoustics, and structure–hydroacoustic engineering applications leads to large systems of equations, and is still a challenge to current high-performance computer systems. The demands for extremely large models are due to large physical domains or the desire to resolve high-frequency levels, at least as long as the different modes are separated, say
Chemical characterization of cyanogen bromide fragments from the beta-chain of human complement factor C3
The isolated beta-chain of human complement factor C3 (C3 beta) was fragmented by cyanogen bromide. Nine fragments were defined by gel filtration and high-pressure liquid chromatography, and characterized with respect to their Mr, amino acid composition and N-terminal amino acid sequence. Approx. 30% of the primary structure of C3 beta was determined. Alignment of the 3 N-terminal fragments allowe
A Pilot study on audio induced pseudo-haptics
In this paper we describe a small pilot study designed to explore the possibility of spatial pseudo haptic effects induced by artificial audio feedback. Four basic audio designs were investigated: pan, continuous since tone, virtual harp and noise. For reference a visual pseudo haptic effect together with real haptic effects were also included. The results indicate noise and spatially distributed
"I'm an ordinary faggot" – Scripts of male homosexuality in urban and rural Sweden in the 1940s
The paper explores the flux of male homosexual identity between urban subcultures and small rural settings in Sweden. Eve Kosofsky Sedgwick has claimed that we cannot interpret Foucault’s History of Sexuality as if one understanding of sexuality was substituted by another, but that many forms of sexuality coexist in any given time. Inspired by her analysis, this paper claims that a shift between t

Polymer Mediated Surface Forces
The issue of controlling the stability between colloidal particles in solution is important, at least for industrial applications, relying on efficient flocculation or stable dispersions. The objective of this thesis is to shed some light on fundamental mechanisms behind the interplay between attractive and repulsive forces, in solutions containing colloids and polymers. We approach the probl

Perpendicular to grain fracture analysis of wooden structural elements - Models and applications
Popular Abstract in Swedish Trä är ett konstruktionsmaterial med många positiva egenskaper, både avseende mekaniska och tekniska egenskaper och avseende det som ibland kallas mjuka egenskaper. Trä har generellt hög styrka i förhållande till sin vikt, det är ett naturligt förnybart material och det anses av många vara estetiskt tilltalande. Jämfört med andra vanliga konstruktionsmaterial som stål oThis thesis concerns experimental and theoretical work regarding perpendicular to grain fracture in wooden structural elements. The experimental part concerns strength tests of glulam beams with a hole. The theoretical parts concern development of two models for strength and fracture analysis, both based on fracture mechanics approaches, and their application to analysis of beams with a hole and d
