Representations of concepts from multivariate statistics are studied using multilinear algebra. Applications are given to the analysis of seasonal multivariate time series. The first paper concerns a class of permutation matrices which are representations of permutation operators on tensor spaces. In the second paper, the derivation of moments and cumulants of Hilbert space valued random variabl

OBJECTIVE: To determine moment arm lengths from seven knee muscles and the patellar tendon. The knee muscles were the biceps femoris, semitendinosus, semimembranosus, gracilis, sartorius, and the lateral and medial gastrocnemius muscles. DESIGN: The moment arms were calculated based on MRI measurements. BACKGROUND: Moment arm lengths of different muscles with respect to the joint centre of rotatio

Popular Abstract in Swedish Stjärnors radialhastigheter har i mer än ett sekel haft betydelse för studiet av Vintergatans och stjärnhoparnas kinematik. Radialhastigheten är den hastighet en stjärna, eller ett annat objekt, har längs synlinjen från en given observatör. Hittills har radialhastigheter bestämts med hjälp av spektroskopi, genom att observera spektrallinjer vars vilovåglängder är kända.This work demonstrates the determination of absolute stellar radial velocities from geometrical principles, i.e. using astrometry. Such `astrometric radial velocities' are obtained independently of spectroscopic information. While spectroscopic radial velocities are affected by line shifts from astrophysical processes on the stellar surfaces, by gravitational redshift and various other effects, as

Complex product form generation methods have rarely been used within the field of industrial design. The difficulty in their use is mainly linked to constraints – such as functionality, production and cost – that apply to most products. By cou-pling a mathematically described morphology to an optimisation system, it may be possible to generate a complex product form, compliant with engineering and

Within the framework of the European project, PROSPER, field experiments with ISA (Intelligent Speed Adaptation) were carried out in Hungary and Spain. Twenty vehicles in each country were equipped with two kinds of ISA systems: 1) warning via an active accelerator pedal and 2) warning via beep signals and flashing red light when exceeding the speed limit. Both systems are based on a GPS receiver

The catalytic properties and the inter-domain electron transfer of cellobiose dehydrogenase (CDH) from the ascomycete fungus Myriococcum thermophilum adsorbed on graphite and thiol (SAM) modified gold electrodes were investigated using cyclic voltammetry, flow injection amperometry and UV-Vis spectroelectrochemistry. The fabrication and characterisation of a noncompartmentalised, mediator and cofa

Boken är en rapport från en konferens på Kreta september 2002. I inledningsanförandet introducerar jag några i den moderna västliga diskussionen vanliga uppfattningar av betydelse för relationen mellan naturvetenskap och religion, bland andra panenteism och kritisk realism. Två exempel illustrerar frågor som berör relationen mellan bioteknologi och kristen antropologi: Möjligheten att med hjälp av

The purpose of this thesis is to study how the Swedish working-class authors, and close friends, Eyvind Johnson (1900-1976) and Rudolf Värnlund (1900-1945) during the interwar period portray the individual and collectives of different kinds. The studied novels are Eyvind Johnson’s Timans och rättfärdigheten (1925; Timans and righteousness), Bobinack (1932), Romanen om Olof (1934-1937; The novel ab

It is well known that Catholic nuns and sisters played an important role in modern society, and that they in many ways paved the way for the entrance of women into professional life within the social sector. Modern research has also pointed out their social achievements as missionaries in the third word. But it is less known that female Catholic congregations also led school, hospitals and other s
