Simulation studies are today an important tool in the development of new networks. For this purpose the NS-3 network simulator can be used. The focus of this thesis work lies on 802.11ac, the latest version of the Wi-Fi standard. NS-3 does not support the IEEE 802.11ac standard and the goal was to implement features for this. Different deployment scenarios were modeled in various conditions and th
Studier har funnit att en liten grupp persistenta våldsbrottsdömda är ansvarig för majoriteten av brottslighet. Syftet med denna studie var att bredda förståelsen för persistens i våldsbrottslighet genom att undersöka dess kopplingar till self-control (självkontroll). Studien undersökte brottshistorik, psykiatriska diagnoser och olika aspekter av begreppet självkontroll i en grupp bestående av 251Studies have shown that a small group of offenders, persistent in violent criminal behavior are responsible for the majority of criminal convictions. The aim of the current study was to broaden the understanding of persistent criminal behavior by investigating its associations to self-control. The study investigated the criminal history, mental health and self-control in a sample of 251 incarcerat
Randall Collins modell för en lyckad interaktionsritual kräver fyra ingredienser; kroppslig närvaro, en tydlig gräns i förhållandet till utomstående, delad fokuserad uppmärksamhet mot samma mål och slutligen att ritualen producerar ett kollektivt medvetande där känslan av tillhörighet blir central. (Collins, 2004) Kollektiv upprymdhet skapas, vilket innebär att deltagare i interaktionsritualen g
Inledning: I Sverige är all personal inom hälso- och sjukvård skyldiga att göra en orosanmälan om de misstänker att barnet de har hand om far illa. Det finns få studier om röntgensjuksköterskans upplevelse av ansvar och skyldigheter i samband med röntgenbesök. Syfte: Att undersöka röntgensjuksköterskans kunskap, upplevelse av ansvar och skyldigheter vid misstanke om att de barn de undersöker utsät
Undersökningen syftar till att beskriva medarbetarnas och ledarnas uppfattningar om det hälsofrämjande arbete som sker på arbetsplatsen. I syftet ingår att kartlägga likheter och skillnader mellan medarbetare och ledares olika uppfattningar. Datainsamling sker med en fenomenografisk utgångspunkt i form av semistrukturerade intervjuer. Intervjuerna äger rum på två olika företag, med två olika arbe
The purpose of this study is to understand how we talk and write about and our understanding of crimes, the perpetrator and victims. By using a gender discourse analysis of the media reporting of a specific crime committed in Sweden, “Knutbydramat” with two perpetrators of different sexes, we aim to see how the media represent and therefore consolidate the social norms in a society. The discourse
In this thesis the observation of the rare associated particle production of a J/psi meson in association with a W boson is reported using 20.3 fb^-1 of data from proton-proton collisions at 8 TeV with the ATLAS detector. Currently, the way a J/psi meson is produced at the Large Hadron Collider is not well understood and there are competing theories to describe this production. In combination with
”Now, we become just as sporadic participants” A qualitative study experience of individual counselor’s facility A counselor at a hospital is a person who is working with the mental health of the patients. Due to today’s fast-pace society stress and other mental health problems has become more and more common which has led to a higher demand of counselor workers. Alongside the practical counseli
This study investigated the empirical generalizability of the relationship between sexual minorities Lesbian, Gay, Bisexual and Transsexual (LGBT), shame and mental and physical health. It was an extension of existing studies and inspired by the framework of Mereish and Poteat’s study in 2015, “A Relational Model of Sexual Minority Mental and Physical Health”. First hypothesis was that there would
Denna uppsats undersöker medarbetarnas syn på den interna kommunikationen på ett fastighetsföretag, med utgångspunkt från en medarbetarenkät utförd av organisationen. Enkäten visar att en del av medarbetarna som arbetar på olika områden, upplever att de får för lite information. Syftet med uppsatsen är att undersöka hur den interna kommunikationen upplevs och fungerar utifrån ett medarbetarperspek
Mapping and quantifying forest information about e.g. land cover, tree height and biomass has traditionally been a both time-consuming and labour-intensive part of forestry and forest research as field measurements typically are collected manually using handheld equipment. Remote sensing has proved to be a valuable complement to field based measurements as it enables for fast and relatively cheap
Education for all, what does it mean? For me, that all children have the right to education and are given possibilities to obtain this right. Though, is that the reality for all children in practice? Several reports, national as well as international, indicate that this is not the case for undocumented children in Sweden, despite their right to actual enjoyment of the rights protected in the Conve
Recruitment plays an important role in an organization on many different levels. A recruiter can, depending on his or her leeway, be considered to have a major influence on the business. An experiment was conducted to find out if real recruiters are focusing on different aspects depending on the job applicant’s ethnic background. Established hypotheses were examined on the basis of the person-envi
In a globalized world organizations and the software industry face issues in developing services for distinct markets and regions. National particularities, apart from linguistic conventions of countries and regions, constitute a pertinacious problem in software development as the implications culture have for localization are difficult to anticipate and address. This thesis strives to shed some
This work relates to the proposed n-nbar experiment at ESS and covers a procedure with which future neutron research can be made using a small TPC prototype. Settings for the GEM amplification voltage supply and main drift field across the chamber have been established using minimum ionizing cosmic muons as a reference. To be able to reconstruct tracks in three dimensions and measure the deposited
Abstrakt Bakgrund: Vårdrelaterade infektioner orsakas av bristfälliga hygienrutiner och bidrar till stor risk för patientsäkerheten. Detta leder till lidande för patienterna och en ökad risk för förlängda vårdtider men även höga kostnader för samhället. Syfte: Denna litteraturstudie syftar till att belysa faktorer som påverkar hygienrutiner som kan minska risken för vårdrelaterade infektioner. Me
Uppsatsens syfte är att undersöka lagändringen den 13 juni 2014 i lag (2005:59) om distansavtal och avtal utanför affärslokaler. Undersökningen utreder avtal på distans och avtal utanför affärslokaler mellan en konsument och en näringsidkare för varor och tjänster. Uppsatsen granskar ändringar där den svenska lagstiftningen är tillämplig men kommer även bestå av EU-rättsligt material. Anledningen This essay’s purpose is to analyze the amendment of 13 July 2014 in the Swedish Distance Contract Act. The study discusses the distance contract and off-premises contracts between a trader and a consumer for products and services. This essay analyzes the changes where the Swedish law is applicable but it will also include analyzes of EU law. The reason is that the amendment is based on an EU Direc
The characteristics of Boron Carbide (B4C) coated polyvinyltoluene scintillators with a sputtered B4C coating ranging between 200 and 1000 nm have been studied using a photomultiplier - Lanthanum Bromide detector setup with a PuBe neutron source. The raw data from the detectors was analysed by imposing a detector coincidence condition. The coated scintillators have been compared with a commercial
