This paper formalizes the use of integral and differential cumulants for measurements of multiparticle event-by-event transverse momentum fluctuations, rapidity fluctuations, as well as net-charge fluctuations. This enables the introduction of multiparticle balance functions, defined based on differential correlation functions (factorial cumulants), that suppress two- and three-prong resonance dec
Beginning with researching past, present and future tent structures, analyzing the tent market and the use of party tents, the initial aim of creating a truly modular party tent that is suited for its purpose was processed, discussed and refined into four design directions. With help from a thorough function analysis and evaluation, a winning direction was chosen and developed further. With help f
During an archaeological excavation in Uppåkra 2010 I found a so-called “guldgubbe”(goldfoilfigure). This find really caught my attention and especially so because their functions are still debated. This master thesis is about the meaning and use of this, more appropriately called, goldfoilfigure. Many attempts to solve the questions surrounding the functions of the figures have been made during t
The purpose of this paper is to investigate how different observers and reporters in the international debate form different opinions concerning current events in the Russian Republic of Chechnya in Caucasus and to try to illuminate what different consequences these different mediaconstructions might have for our public and political understanding of the situation, and the consequences these views
Populärvetenskaplig sammanfattning: Är det möjligt att bestämma geokemi i fält? Geokemisk analys kan utföras på några minuter utan någon förberedelse av provmaterial med en portabel XRF (röntgenfluorescens). Om man gör ett pulver av provet blir resultaten bättre. Portabel XRF är dock inte någon metod som används mer än i första stadiet. Frågan är hur mycket sämre resultaten för ytanalyser blir är The development of XRF instruments (x-ray fluorescence) has enabled faster analysis with simple preparation of the material. It is also contemplated that one should bring the instrument in field and analyze surfaces without any sample preparation. In this study, a new geochemical analysis of Karlshamn dyke made by portable XRF-analysis is presented. Twelve samples were analyzed of powder, represen
The global pandemic COVID-19 made it impossible for psychodynamic psychotherapists to continue with in-person psychotherapy and they had to transform their work to the digital platform. There is a research gap regarding psychodynamic psychotherapists experiences of video-delivered psychotherapy which is emergent to investigate since previous research has shown that the therapeutic relationship suf
This master degree project has had the purpose of designing a chair for small scale serial production in Sweden. Origin has been a big focus point, and the wood has been carefully selected to minimise ecological footprint through transportation of the product. Another focus point has been the complicated process of designing a chair that is unique. The report includes the background of the carpent
A small wind power plant connected to the grid has been modeled in Modelica/ Dymola and controlled using external controllers written in C++. The small wind power plant consists of three wind power units with a nominal power of 3kW and one grid connection interconnected with an internal DCgrid. All the controls needed for control and optimization for the operation of the individual parts in the pl
Abstract The aspiration of this essay was to search for explanations why children who are victims of sexual abuse don´t tell someone immediately about their horrifying experiences. Commonly, their way of dealing with the trauma is instead silence for many years until they decide to reveal the abuse. I have read four autobiographies written by people who were themselves, when they were children, vi
Tall buildings have lately become a problem to design because of the development of light weighted steel frames and wind loads. An important task of a structure is the absorption of horizontal loads and the capacity to transfer the resulting moment down into the ground. It is the engineer’s task to make sure that the structure’s performance is sufficient when it comes to safety and serviceability.
Det har skrivits mycket om Karen Blixen genom åren, både av danska, svenska och engelsktalande författare. Hennes liv och författarskap har fascinerat många, så även mig. I min uppsats kommer jag att ta fasta på några frågeställningar med anknytning till Den afrikanske farm. Ett syfte är att belysa genreproblematiken, och svårigheten att sätta in Den afrikanske farm i något av de vedertagna genre
Monte Carlo simulations have been performed for two simple models of a titrating polyelectrolyte: (i) a rigid rod and (ii) a freely jointed chain. Both models have fixed bond lengths, and the polyelectrolyte charges interact through a screened Coulomb potential. Chains consisting of 80-1000 monomeric units have been studied at three salt concentrations: 0.001, 0.01, and 0.1 M. Conformational prope
Lately, different wearable form factors have reached the consumer domain. Wearables enable at-a-glance access to information and can continually sense the surrounding environment. Internet of Things (IoT) researchers have focused on the main enabling factors: The integration of several technologies and communication solutions. Less effort has been devoted to exploring how not-so-tech-savvy end use
To harvest the benefits of III-V nanowires in optoelectronic devices, the development of ternary materials with controlled doping is needed. In this work, we performed a systematic study of n-type dopant incorporation in dense InxGa(1-x)P nanowire arrays using tetraethyl tin (TESn) and hydrogen sulfide (H2S) as dopant precursors. The morphology, crystal structure and material composition of the na
Mushroom bodies are the iconic learning and memory centers of insects. No previously described crustacean possesses a mushroom body as defined by strict morphological criteria although crustacean centers called hemiellipsoid bodies, which serve functions in sensory integration, have been viewed as evolutionarily convergent with mushroom bodies. Here, using key identifiers to characterize neural ar
We have estimated the activation energy for aromatic oxidation by compound I in cytochrome P450 for a diverse set of 17 substrates using state-of-the-art density functional theory (B3LYP) with large basis sets. The activation energies vary from 60 to 87 kJ/mol. We then test if these results can be reproduced by computationally less demanding methods. The best methods (a B3LYP calculation of the ac
This document describes the package CHIRON which includes two libraries, chironitself and jbnumlib. chiron is a set of routines useful for two-loop numerical results in chiral perturbation theory (ChPT). It includes programs for the needed one-and two-loop integrals as well as routines to deal with the ChPT parameters. The present version includes everything needed for the masses, decay constants
In iterative receiver structures, soft information becomes available after the decoding stage in the first iteration. This information is used to enhance the quality of the channel estimates for the next iteration. Channel estimation plays a crucial role in multi-user detection because the effective identification sequence for each user strongly depends on the channel characteristics. To combine d
Popular Abstract in Swedish Avhandlingen behandlar robotteknik och de nya möjligheter som den kan ge människor med rörelsehinder. Jag fokuserar på teknikanvändaren och teknikanvändningen, speciellt på vad som gör robothjälpmedel värda att använda. Distinktion görs mellan användvärdhet och användbarhet. Erfarenheter från användning av den rullstolsmonterade robotarmen Manus visar att tekniska krav
