This thesis handles time frequency analysis of EEG signals measured on participants performing the so-called flanker task. The analysis is done mainly using multitapering techniques on the quadratic class. Using multiple orthonormal windows when estimating the spectra of a process, one lowers the variance of estimate. A class of locally stationary processes (LSP) is presented to use as a model of

Det finns idag mycket kunskap om vad som anses utgöra en grund för en bra design i ett användargränssnitt för webben. Olika privata och offentliga organisationer har försökt samla delar av denna kunskap i s.k. stilguider för webben i syfte att användas som en bas vid utveckling av produkter och tjänster för att på så sätt definiera en enhetlig känsla och ett gemensamt utseende i ett gränssnitt.

This thesis explores the potential of broadening the scope of social movements for sustainability. The implicit assumptions of the causal mechanisms for strategic social change propose limits to what transformative social action can be, and risk overlooking untapped resources for change. To address these limitations I use Habermas’ critical social theories on public engagement, systemic rationalit

The purpose of this study is to examine how offender profiling is being used in Sweden and how investigators working at different police departments perceive it as a method. To get ahold of empirical data I conducted a total of four interviews. To fulfill my purpose I first had to describe the offender profiling in Sweden with help of the interview with a representative for Gärningsmannaprofilgrup

The purpose of this paper is to analyze the sermons and speeches of Lewis Jonsson (1874-1918.) He was vicar of Höör and Munkarp parishes between 1913 and 1918. Lewis Jonsson came from a small village, Sebbarp, in Skåne. As a young boy he studied in Gothenburg, where he lived during term time with his sister and her husband. He started studying for the priesthood at Lund University and graduated in

Which sources most influence the language spoken in Israel? Is it the same language as the Hebrew of its ancestral heritage? Which periods in history brought about the changes of contemporary lexicon? These are the questions addressed in the current essay, which presents the inspection of nouns appearing in a recent newspaper, and their categorization according to the different periods in the his

The present study seeks, with a corpus of eight Japanese works of fiction, to identify if the speech patterns of Westerners in Japanese literature have their origins in the simplified register referred to as “foreigner talk”, i.e. the register used to address non-native speakers with low linguistic competence, and also if foreigner talk is commonly used in Japanese literature for addressing non-na

Ett försök att placera in den folkkäre underhållaren Hans Alfredson i en litterär medvetenhet. Genom en undersökning av Alfredsons berättarteknik i dennes dagboksroman Gummitummen, placeras boken in i sin litterära samtid, nämligen det konkreta sextiotalet. Uppsatsen fokuserar på att kartlägga hur Alfredson angriper dagboksromanens konventioner genom att applicera de generiska koder jag har kommit

The main purpose of this thesis is to add to the conceptual understanding of gender in management consulting, as portrayed through the lens of popular culture. It is further aimed to highlight the reciprocal relationship between popular culture research and the study of organization/ management consulting studies. Thereby, we hope to contribute to the existing literature that treats gender in mana

Populärvetenskaplig sammanfattning Klimatförhållandena i norra Kina samt Mongliet gör dessa områden benägna att drabbas av mark-försämring, vilket i sin irreversibla form ofta hänförs som ökenspridning. Litteraturstudien fokuserar på både tidigare erfarenheter, så som vad olika åtgärder har haft för konsekvenser- bra som dåliga – och även vad olika sätt att sköta marken på har medfört, samt även aThe climatic conditions in northern China and Mongolia make these regions prone to desertification. The results showed that there is quite a lot of disagreement in this matter, as to whether it exists at all and if so what the major explanatory factor is. Some argue that the desertification is due to climatic/natural factors (almost) alone, others that human activities is the major cause, and some

Introduction: Platelet transfusions are often used when thrombocytopenic patients are facing a central venous catheter (CVC) insertion, but their use has been up to debate. Point-of-care devices such as thromboelastometry (ROTEM) and platelet aggregometry (Multiplate) better reflect in vivo haemostasis than routine coagulation tests. Aim of the study was to investigate the effects of platelet tran

Organisationer väljer molnet då det ger dem möjlighet till kostnadsbesparingar och att få del i skalbara IT-lösningar för att inte bli begränsade av IT-resursernas kapacitet. Att migrera från en plattform till en molntjänstleverantör kan skapa problem för organisationen. Uppsatsen avser att belysa problematiken som uppstår mellan organisationen och molntjänstleverantören vid en migrering till moln

ABSTRACT The existence of sound symbolic and mimetic words in the Japanese language is well known. Although the most common appearance of these sound symbolic words occurs in Japanese comics they do exist in many other forms of media, ranging from television shows to everyday conversation. These words, a very good tool for the native Japanese speaker to convey intimate meanings and sensations, po

The purpose of this thesis is to investigate how accurate multiple valuations are in relation to the DCF. Furthermore, the accuracy of equity and entity multiples will be compared. Finally, we will try to determine the factors underlying the valuation errors. Our results suggest similar performance from the multiples approach in relation to the DCF model in estimating corporate value with eight

Populärvetenskaplig sammanfattning Fenologi innebär studier av naturligt återkommande händelser som till exempel bladsprickning, knoppbristning och vissningen av blad. Det är viktigt att förstå hur klimatförändringen påverkar tidpunkten då dessa händelser sker eftersom det i sin tur påverkar kol-, närings- och den hydrologiska cykeln. Fältobservationer har varit den mest använda metoden för att saPhenology is the study of the timing of natural events such as leaf-out, bud burst and senescence relative to climate change. It is important to understand how the climate change will affect the timing of these events as it in turn affects the carbon-, nutrient- and the hydrological cycles. Field observations is the most common way to gather phenology data but the result is dependent on the skill

Today there are several public libraries in Sweden that are engaged in the campaign Digidel 2013, a campaign that aims to increase the digital participation among citizens. The democratic aspects of such activities are the focal point of this thesis. The purpose of this master’s thesis is to contribute to a better understanding of the public libraries exercise of their democratic and social func

Abstract Authors: Nina Niemelä and Christian Persson Title: About the art of being a relative – a qualitative research about being the relative of a person who is abusing drugs Supervisor: Lars Harrysson This study is written as an attempt to shed light on the relatives to people who are abusing drugs or alcohol. We have aimed to explain and research how the relatives are effected by and handle t

Jag har genomfört en kvalitativ innehållsanalys av olika tidskrifter, tillgängliga på den svenska marknaden. Samtliga tidskrifter inriktar sig mot den medvetne konsumenten – konnässören. Syftet med analysen är att kartlägga och förklara konnässörskapet, dess uppbyggnad och funktion, samt att söka förståelse i hur det kan finnas utrymme till alla dessa konnässörtidskrifter, och varför just nu – i d

The main goal of this study is to develop a prototype version of a microphone-based conferencing system built on Apple iPhone and iOS. This study also evaluates if the system is applicable in a naturally occurring context. The prototype is based on two iOS units, iPhone or iPad, where one unit acts as a transmitter and the other as a receiver for human speech. The requirements state that a WiFi-ro

Konceptet SUPPORT strävar efter att hjälpa människor att lättare kunna vila/sova sittandes upp i bilstolen. Med hjälp av stöd som går att dra ut från nackstödet kan huvudet på ett bekvämt sätt lutas mot sidorna och få det stöd som saknas för en bekväm och avslappnad sittställning.
