    Algorithms and Interaction Potentials: phase density, surface tension and carbon dioxide

    No full text
    This thesis is an amalgamation of articles (Papers I–V) by the author. We present a perturbation algorithm to calculate the phase density, and thus the partition function including its temperature dependence. It works for Hamiltonians that are not too dissimilar, for which an extra degree of freedom interpolating between the two is defined so that microcanonical sampling allows the calculation of the ratio between the phase densities at any energy. The method is illustrated on a number of problems of different dimensionalities. In Paper I, we consider an anharmonic Einstein crystal, the square-well tetradecamer, and liquid gold. In addition, we consider the one-dimensional rotor and the low-dimensional ideal gas in a homogeneous external field, two Hamiltonians that display a phase transition at well-defined critical energies. We consider the interaction of linear molecules and discuss two coarse-grained pair potentials for their description. In Paper III, one of these potentials has been parametrized for the vapor-liquid envelope of carbon dioxide using two adjustablesobtaining good agreement, but for a detailed description of the carbon dioxide dimer and trimer structures, such coarse-graining fails. As reported in Paper IV, conventional all-atom force field descriptions also fail in describing the experimental second and third virial coefficients but an all-atom description with coarse-grained, single-site anisotropic three-body dispersion and single-site electrostatic induction manages to reproduce them. In addition, we note that this simple anisotropic three-body dispersion correction is essential for predicting the correct relative stability of the experimental trimer conformations when combined with a literature parametrization of the dimer ab initio potential energy surface. We present a simple method for calculating the surface tension with respect to vacuum from cluster simulations, by relating the scalar pressure to the infinitesimal isothermal pressure-volume work and equating it with the expression from classical nucleation theory. We then discuss the effect of molecular polarization on the surface tension using this method, as well as study its effect on the second and third virial coefficients of the fluid of polarizable Stockmayer molecules. The surface tension increases with polarizability, but so does its rate of decrease with temperature. The Tolman length is found positive and largely insensitive to temperature but increases non-linearly with increasing molecular polarizability. We discuss the semi-empirical calculation of the crystal-water surface tension of the pharmaceutical bicalutamide as reported in Paper V and provide a slight modification of the procedure

    Bibliometric author evaluation through linear regression on the coauthor network

    The rising trend of coauthored academic works obscures the credit assignment that is the basis for decisions of funding and career advancements. In this paper, a simple model based on the assumption of an unvarying “author ability” is introduced. With this assumption, the weight of author contributions to a body of coauthored work can be statistically estimated. The method is tested on a set of some more than five-hundred authors in a coauthor network from the CiteSeerX database. The ranking obtained agrees fairly well with that given by total fractional citation counts for an author, but noticeable differences exist

    Tireless in His Service: Rasmus Andersen, Pastor and Author 1878-1924

    No full text
    Of the four founders of the Danish Lutheran Church in America in 1872, the one concerning whom the most information exists is Rasmus Andersen. Yet it has been my observation that comparatively little is known about him. A reason for this is that, to my knowledge, no comprehensive biography exists, and there is almost nothing available in the English language. Most of the material that does exist is to be found in the Danes World Wide Archives ( Udvandrerarkivet ) in Aalborg, Denmark. According to Birgit Flemming Larsen, who oversees that archive, the Andersen collection is the largest at the Aalborg archive. It consists of 104 archival boxes, filled with books, letters, diaries, memoirs, ministerial records, copies of letters sent, unpublished manuscripts and much more. The Danes World Wide Archives constitutes a treasure trove for the researcher who is interested in Rasmus Andersen

    Fem och en halv komposition : Skriftlig reflektion inom självständigt, konstnärligt arbete

    No full text
    In this work I have explored different ways of communicating the notated music (even in a more abstract form) to the musicians. How can I develop the aesthetics I am aiming for by using specific techniques in notation. I have also investigated how to incorporate the strengths of each improviser and whether it is possible to use these strengths as a compositional factor The group consists of a group of seven musicians playing 9 different instruments in total: trumpet, trombone, mellophonium, alto saxophone, tenor saxophone, clarinet, bass trombone, double bass and drums. During this project I wanted to make the most of composing and arranging for this particular constellation of instruments and the musicians who plays them.   The music I have written is for the most part influenced by jazz but sometimes bordering to a more classical or orchestral approach. In this project, I have challenged myself as an instrumentalist and a composer by utilizing a low C-string on the double bass. And while it made some passages more technically difficult to execute on the instrument, it has pushed me forward as a composer in wanting to explore all the different sounds and timbres available. The project resulted in a recording session at Sunnanå Studio, Sweden.Repertoar samt mediedokumentation:1.

    Perehdytysopas Pirkanmaan saneerauspalvelu Oy:lle

    No full text
    Tämän opinnäytetyön tarkoituksena on perehdytysopas toimeksiantajayritys Pirkanmaan saneerauspalvelu Oy:n uusille työntekijöille. Yrityksellä ei ole aiemmin ollut perehdytysopasta työntekijöilleen, vaan uusien työntekijöiden perehdytys on toteutunut kokeneempien työntekijöiden toimesta työmailla. Lisäksi perehdytyksen yhteydessä yrityksen hallilla on pidetty perehdytyskierros, jolloin työnjohto on näyttänyt eri materiaalien sijainnit, kertonut lyhyesti yleisiä asioita yrityksestä ja työntekijän työtehtävistä. Tämän opinnäytetyön tavoitteena on, että jatkossa uusien työntekijöiden töiden aloittaminen on helpompaa sekä selkeämpää. Lisäksi tavoitteena on myös vähentää työnjohdon sekä kokeneempien työntekijöiden kuormitusta uusien työntekijöiden perehdyttämisessä. Opinnäytetyössä perehdyttämisen lisäksi työssä käsitellään rakennusalan työturvallisuutta, työsuoritteita ja niissä käytettäviä materiaaleja. Työssä tarkastellaan myös työkoneiden ja- välineiden turvallista käyttöä, Easoft-toiminnanohjausjärjestelmää sekä laadunvarmistukseen liittyviä asioita. Lopuksi pohditaan mahdollisia jatkotoimenpiteitä. Tämän perehdytysoppaan tekemiseen on kerätty tietoa kirjallisista lähteistä, haastateltu pitkään yrityksessä olleita ammattilaisia sekä tämän opinnäytetyön tekijän kokemuksia rakennusalalta. Tulevaisuudessa perehdytysopas on tarkoitus jakaa uusille työntekijöille (työsopimusta kirjoittaessa) sekä uusille vuokratyöntekijöille. Uusien työntekijöiden sekä vuokratyöntekijöiden tulee tutustua perehdytysoppaaseen ennen varsinaisten töiden aloitusta. Perehdytysopasta voidaan tulevaisuudessa muokata työnjohdon toimesta työntekijöiltä kerätyn palautteen perusteella. Lisäksi opasta muokataan, mikäli yrityksen toimintatavat ja työsuoritteet muuttuvat.The purpose of this thesis is an orientation guide for the new employees of the employer company Pirkanmaan Saneerauspalvelu Ltd. The company has not previously had an orientation guide for its employees, so the orientation of new employees has been implemented by more experienced workers in the workplace. In addition, during the orientation an induction tour has been held in the hall, where the supervisors have shown the locations of different materials, briefly told general things about the company and which tasks belong to whom. The objective of this thesis is to make it easier and clearer for the new employees to start working. In addition, the aim is to reduce the burden on supervisors as well as more experienced employees when orienting a new employee. In addition to orientation, this thesis deals with construction occupational safety, work processes and the materials used. The work also examines the safe use of machines and equipment used to work, ERP system called Easoft and issues regarding quality assurance. In the end potential follow-ups are pondered. To create this orientation guide information was collected from various written sources. In addition, professionals working in the company has been interviewed and the own experiences of the author of this thesis on the construction industry has been collected. In the future, the orientation guide will be distributed to new employees when writing an employment contract and also for new agency workers. The new employees as well as the agency workers should read the orientation guide before starting the actual work. In the future, the orientation guide can be modified by the management based on feedback from employees. In addition, the guide will be modified according to the changes of the company's policies and processes

    Rasmus Sorensen and Danish Emigration, 1847-1863

    No full text
    Probably no individual played a more seminal role in the limited Danish emigration to North America before and during the Civil War than Rasmus Sorensen. From the late 1840s until the early 1860s this author, educator, politician, and social reformer led three groups of his countrymen to Wisconsin and, through numerous booklets, speeches, and letters encouraged others to settle elsewhere in the United States and Canada. Yet Sorensen has generally been little more than a supernumerary in the historiography of this transatlantic migration. Its pioneering historian, Peter Sorensen Vig, devoted twelve pages to him in his mammoth compendium, a dozen more than John Bille allowed him in his disjoint narrative of 1896. Arne Hall Jensen described Sorensen \u27s life in two paragraphs in 1937, giving various biographical details without interpreting their significance. There is little to indicate that the recent revival of interest in the Danish-American field will reverse this long tradition of neglect. In his monumental study of emigration from Denmark, Kristian Hvidt relates his activities in a scant paragraph, perhaps justifiably, because Sorensen \u27s lifespan fell completely outside Hvidt\u27s chronological framework

    Downgrade

    No full text
    A downgrade (or downgrading, downgraded) has been used in slightly different ways throughout the CA and IL literature, but always with a general sense of scaling down or attenuating a turn or action, usually with respect to something prior. The point of comparison may either be others’ prior talk or one’s own talk, or some unmarked default turn design, against which different alternative formulations are measured

    Turn allocation

    No full text
    Turn allocation is one component of the turn-taking system, the other being the turn-constructional component (Sacks, et al. 1974). The turn-allocational component refers to the coordinated ways in which speakership is transferred among participants at transition-relevance places (TRPs)

    Turn holding

    No full text
    Turn holding, also known as floor holding, refers to practices that a current speaker may deploy to inhibit what might otherwise be hearable as a transition-relevance place (TRP) (see, e.g., Selting 2000). Current speakers thereby work to secure speakership beyond such points, engendering a projected or actual multi-unit turn

    Registering and repair-initiating repeats in French talk-in-interaction

    No full text
    This article examines the prosody and sequential organisation of repeats in French talk-in-interaction. Repeats in French are used for initiating repair, as well as for registering receipt. I show for two sequential contexts – after first pair parts and after second pair parts – that the action import of the repeat depends on its prosodic design; prosody allows participants to differentiate between repair-initiating (i.e. questioning) and receipt-registering repeats. While questioning repeats make a response conditionally relevant, registering repeats do not – however, they do not preclude a response either. Registering repeats are sometimes responded to with confirmation tokens, and sometimes not; when produced, such responses are a contingent possibility rather than an expectable second pair part. In the selection and design of confirmation tokens, participants distinguish between solicited and volunteered confirmations. The article relates these findings to prior research on repetition and sequence organisation in French and also in English, Russian and Finnish.</p
