Seediq – antisymmetry and final particles in a Formosan VOS language

This paper presents data from the Austronesian language Seediq, spoken in taiwan, which has both VOS order and final particles. It will be argued that the coccurrence of these two features is unexpected under a pre-antisymmetric analysis, whereas it is easily captured under an analysis couched in Kayne's Antisymmetry model, under the assumption that VOS order is derived by raising the predicate to

Master's Theses in Automatic Control 1984-1985

The report contains abstracts of Master theses (examensarbeten) made at the Department of Automatic Control, Lund, during the academic year 84/85. During this year 16 theses were made by 18 students. Most of the theses are written in Swedish with an English abstract.

Stability of a single vortex in a trapped Bose-Einstein condensate

We investigate the lowest state of a Bose-Einstein condensate with an off-center vortex state that is confined in a rotating harmonic potential. Our results are consistent with the fact that any single off-center vortex is unstable. Furthermore, a vortex state located at the center of the cloud first becomes locally stable as the rotational frequency increases. Finally our study implies the existe

On upward flame spread on thick fuels

Saito, Quintiere and Williams (1) developed an integral equation derived from quasi-steady thermal flame spread theory to describe spread up a thick solid. Allowance was made in this purely thermal model for a varying rate of pyrolysis and the relationship between flame length and burning rate was linearised. They discussed asymptotic solutions to their equation and derived the requirements for tw

On a phase diagram for random neural networks with embedded spike timing dependent plasticity

This paper presents an original mathematical framework based on graph theory which is a first attempt to investigate the dynamics of a model of neural networks with embedded spike timing dependent plasticity. The neurons correspond to integrate-and-fire units located at the vertices of a finite subset of 2D lattice. There are two types of vertices, corresponding to the inhibitory and the excitator

On the time-domain version of the optical theorem

The time domain version of the optical theorem is discussed. The theorem relates the sum of the scattered and absorbed energies, for a plane pulse that is scattered from a bounded obstacle, to the far field amplitude in the forward direction. Several fundamental results concerning the scattered and absorbed energies that follow from the theorem and from causality are discussed. Some results are ve

Linewidth modelling of C2H2-N-2 mixtures tested by rotational CARS measurements

The acetylene-nitrogen system is investigated in a combined theoretical and experimental effort in view of its thermometry applications. Accurate values of the rotational Raman linewidths of acetylene are of crucial importance for the computation of spectra from rotational coherent anti-Stokes Raman scattering (CARS) used for temperature and concentration evaluations. Since the direct measurements

Measurement of inclusive jet cross sections in photoproduction at HERA

Inclusive jet cross sections are measured in photoproduction at HERA using the H1 detector. The data sample of e(+)p --> e(+) + jet + X events in the kinematic range of photon virtualities Q(2) less than or equal to 1GeV(2) and photon-proton centre-of-mass energies 95 less than or equal to W-gammap less than or equal to 285GeV represents an integrated luminosity of 24.1pb(-1). Jets are defined usi

Isolation of alkylresorcinols: Classical and supercritical CO2 extraction methods

This chapter focuses on the use of different methods for isolation of alkylresorcinols. Alkylresorcinols are members of a lipid group called non-isoprenoid phenolic lipids. Different aspects of the extraction by classical methods and supercritical CO2 are discussed. Supercritical CO2 extraction of alkylresorcinols from rye bran is discussed for the first time. As compared to the classical extracti

Long-term Effect of Silica Fume on the Principal Properties of Low-Temperature-Cured Ceramic.

This article outlines an experimental and numerical study of the long-term interaction between silica fume and Portland cement in low-temperature-cured ceramics such as concrete subjected to air, water and sealed curing. For this purpose about 2000 kg of eight qualities of concrete were studied at 4 different ages, each over a period of 90 months. Half of the concretes contained 10% silica fume. P

A compilation and evaluation of species in the general Stephanodiscus, Cyclostephanos and Cyclotella with a new genus in the family Stephanodiscaceae

This paper includes species investigated through many years starting with original material from museum collections. A great number of species in the genera Stephanodiscus Ehrenberg, Cyclostephanos Round and Cyclotella (Kutzing) Brebisson, all in the family Stephanodiscaceae Makarova, are presented with holo-, lecto- and/or neotypes, type locality and information concerning nomenclature. A typus g

Recursive Structure and Motion from Image Sequences using Shape and Depth Spaces

In this paper a novel recursive method for estimating structure and motion from image sequences is presented. The novelty lies in the fact that the output of the algorithm is independent of the chosen coordinate systems in the images as well as the ordering of the points. It relies on subspace methods and is derived from both ordinary coordinate representations and camera matrices and from a so ca

Treatment strategy, disease activity, and outcome in four cohorts of patients with early rheumatoid arthritis

Objective-To compare four different inception cohorts of patients with early rheumatoid arthritis (RA) with respect to treatment strategies, disease activity, and outcome during a five year follow up period. Method-Data from cohorts of patients with early RA, with a standardised assessment at least every six months for five years from four different centres, were included in one database. Owing to
