Tool support for design patterns using specification with reference attributed grammars

Design patterns are abstract descriptions of solutions to often recurring problems. They are a means to communicate experience in design. Over the past years, along with the increase in popularity of object-oriented design patterns, some problems with the use of them have been identified. One of these lies in documenting software systems using design patterns. Experience has shown that both in the

Vowel quantity in West Swedish - the villain of the piece?

This paper consists of two, somewhat disparate parts. In the first part, some experiences of two years of fieldwork are summarized, concentrating, as the subtitle suggests, on the very heart of phonetic fieldwork: the encounters and interviews with the informants. As a result of the fieldwork, the project now has access to recordings from approximately 1300 speakers of more than 100 dialects of Sw

Diffusive-Ballistic Heat Transport in a Two-Dimensional Square Plate Using Energy Conserving Dissipative Particle Dynamics

Diffusive-ballistic heat transport in a two-dimensional square plate was simulated using energy conserving dissipative particle dynamics (DPDe). The solution domain was considered to be a two-dimensional square plate surrounded by walls at constant temperatures, where DPD particles are uniformly distributed. The effects of phonon mean free path was incorporated by its relation to the cutoff radius

SI vid LTH: Rapport om SI-verksamheten vid LTH 2011/12-2013/14

Supplemental Instruction (SI) är som framgår av namnet ett komplement till den ordinarie undervisningen i en kurs. Tanken med SI är att inlärningen av ett ämne förstärks genom utbyte av tankar och idéer mellan studenterna. Vid LTH är SI-verksamheten knuten till en initiell ”svår” kurs för nybörjarstudenter. SI sker i möten om ca 5-15 studenter där diskussionen leds av en äldre student. Den äldre s

Material forces in computational single-slip crystal-plasticity

In this contribution, we elaborate the material force method with application to standard dissipative materials, in particular crystal-(elasto)plasticity. It thereby turns out that material heterogeneities caused by the gradient of the corresponding slip parameters induce additional material volume forces. As a result, we observe that these forces contribute to computations of typical boundary val

Luminosity determination and simulation of the LUCID detector at the ATLAS experiment

The aim of this thesis is to describe how the luminosity can be measured in the ATLAS experiment at the Large Hadron Collider. Luminosity is a fundamental quantity that is used in most physics studies at the LHC. For example in order to measure cross sections. Firstly, the detector description of LUCID which has been implemented in the global ATLAS software framework is described and validated. Se

Chemical and Morphological Characterisation of Aerosol Particles in the Tropopause Region

Popular Abstract in Swedish Små partiklar i form av vätska eller fast material mellan 0.001 till 100 µm i diameter, kan sväva i luften och kallas då aerosolpartiklar. De påverkar direkt på klimatet genom att reflektera solstrålar ut till rymden. Detta gör att vi får ett kallare klimat. Indirekt kan de påverka klimatet genom att verka som kondensationskärnor vid molnbildning. Med detta påverkar de The aim of this work was to study atmospheric aerosols, focusing on the chemical composition, the morphology and the origin of the aerosol in the upper troposphere and lowermost stratosphere. An aerosol sampler was developed for this purpose. A new method for quantitative analysis of the major components of the aerosol, i.e. C, N and O was developed, and methodologies for single-particle analysis

The interplay between money market development and changes in monetary policy operations in small European countries, 1980-2000

We study the interplay between money market development and changes in monetary policy operating procedures in 11 European countries from c. 1980 up to the launch of EMU. Aspects of money market development such as the size and structure of different market segments, and institutional and regulatory changes, are addressed. We recount and empirically examine the extent of reorientation of monetary

Collaborative music making and artistic agency

The focus of this chapter is on musical agency in professional contexts and in Higher Music Education (HME). What is musical agency? How can musical agency be investigated, promoted, and developed? Cultural-historical activity theory approaches hold a potential for exploring and answering such questions with a dialectical perspective on creativity. Three examples of interventionist studies from a

Near BER optimal partial response codes

Partial response signaling (PRS) codes with maximal minimum Euclidean distance have previously been found by linear programming. These perform very well in the narrowband-high energy region, but they were not optimized for minimal bit error rate (BER), so they are only optimal in the limit of infinite signal to noise ratio. Here we search for codes that perform better for more practical signal to

Polyamine-Dependent Early Cellular Signals and Cell Proliferation

When a resting cell is awakened to enter the cell cycle by mitogenic stimulation, a complex molecular machinery involving positive and negative regulation of cell-cycle progression is initiated. Part of the machinery is quite well-known. It involves receptors of various kinds, protein interactions, phosphorylation reactions, and molecular cascades carrying the signal to enter the cell cycle from t

Dual band ISM 2.4 GHz and 5 GHz finger antenna

A dual band antenna for two ISM bands at 2.4 GHz and 5 GHz has been evaluated. The antenna structure derives its advantage by deploying several radiators as fingers spreading from a single feeding point. Each radiator functions as both a half-wave and a quarter-wave radiator. Arranging them in parallel matches the half-wave resonance to 50 W. By carefully selecting the angle to ground plane and us
