Realistic radio channel models are crucial for the success of vehicle-to-vehicle (V2V) system investigations. In this paper, we summarize the important parameters for V2V channel models and describe relevant measurement campaigns. Also, we develop and evaluate an ns-3 simulation model of a realistic V2V channel model that is based on measurements in Sweden. The channel model incorporates the effec

The use of duty-cycled ultralow-power wake-up receivers (WRxs) can significantly extend a node lifetime in low-power sensor network applications. In the WRx design, both the low-power operation of the WRx and the wake-up beacon (WB) detection performance are of importance. We present a system-level analysis of a duty-cycled WRx design, including an analog front end, a digital baseband, the WB stru

In this paper, optimization problems arising in model predictive control (MPC) and in distributed MPC aresolved by applying a fast gradient method to the dual of the MPC optimization problem. Although the development of fast gradient methods has improved the convergence rate of gradient-based methods considerably, they are still sensitive to ill-conditioning of the problem data. Since similar opti

In the Gambia, Osusu has helped women to be resilient to various types of precarity for a long time. Though the country has recently recognized the importance of financial inclusion by adopting a National Financial Inclusion Strategy (NFIS), the informal practice of Osusu continues to exist and evolve. Through 20 semi-structured interviews with women who are members of Kafoos that operate Osusu, t

Modern societies rely on a stable supply of electric power from highly complex energy systems. Balancing demand and supply at electricity markets becomes increasingly challenging with the rising share of highly volatile renewable energy sources (RES) and the influence of climate change. Within this uncertain environment, actors face major challenges for planning and decision making. Thus, this the

Large capital inflows have always been a cause of concern for policy makers. While most countries experience episodes of large capital inflows, Advanced Economies tend to fare slightly better, while Emerging Economies experience more adverse effects. This study identifies 228 such episodes of large capital inflows in 1980-2019, in 38 countries. Further, an attempt is made to analyse the aftermath

This study analyzes the European Union’s (henceforth EU) terrorism agenda. The overarching aim of the research is to gain in-depth knowledge and understanding of how the EU represents the problem of terrorism and what solutions they present to counter it. Hence, Lasse Lindekilde’s (2012) model, which he used to study the Danish government’s counter- radicalization Action Plan, is adopted, and used

Due to COVID-19, many organisations have switched to a predominantly remote working environment. Whereas formal meetings have quickly been integrated, informal commu-nication appears to be more difficult online. Despite the importance of informal commu-nication and several positive outcomes of informal communication on employees, this aspect has largely been neglected in organisational communicati

This study investigates the relation between preferences and cognitive effort in decision making tasks in a natural setting. Does the way a supermarket’s shelves are organized affect how easy it is to choose what items to purchase? Does it affect the quality of our choice? The eye-movements of participants were recorded during their regular shopping trips in two supermarkets with different shelf

This thesis explores the relationship between feminism and advertising from the individual woman's perspective. In-depth qualitative interviews with fourteen Swedish women have been conducted, in which a number of feminist advertisement videos have been viewed and discussed. This has been done in order to explore which audience reactions and actions that these advertisements generate; an area

This is a comparative case study of the Committee of the Regions and regional offices. It explores using written records whether history can unveil contrasting features between these two systems using historical institutionalism as the guide. First, it examines the beginning of regional engagement in the European Union with the formation of European Regional Development Fund and the Single Europea

This thesis puts forward the idea that the radical other that constitutes and threatens our society is not to be found outside its limits, but that it is something inherent to our society. It proposes that the threatening other, the constitutive outside of society, is the subject 'the poor', that in its failure to partake in the labour market, fails to conform to the rules of the market, a

This paper discusses the relationship between the Mouridiyya order and the Jamatou Ibadou Rahmane Association- two significant and quite different Muslim organizations in Senegal. This case is illuminated in order to help explain why supposedly opposed groups entertain peaceful relationships. The data analyzed derives from nine interviews conducted between January 2014 and March 2014, in Dakar, Se

Syftet med den här uppsatsen är att undersöka definitonen av en icke-internationell väpnad konflikt. Konflikten i Libyen respektive Syrien kommer att användas som exempel på hur olika detta kan tolkas. Definitonen av en konflikt är av stor betydelse för vilka regler som ska appliceras på den och för straffansvar. IIVK regleras i internationell humanitär rättsliga (IHR) konventioner som GenèvekonveThe purpose of this paper is to examine what constitutes a non-international armed conflict (NIAC), using the conflicts in Libya respectively Syria as examples of how different this can be interpreted. This definition is of great importance when it comes to what rules to apply and criminal accountability. NIACs are regulated in international humanitarian law (IHL) conventions such as the Geneva Co

When girls in Japan acquired the right to higher education in the wake of the Meiji reformation in the 19th century, these girls began to talk in a way that was considered vulgar by the public. It was called teyo dawa kotoba (teyo dawa speech) – and over time it became what we call female speech today. During the Meiji and Taisho periods proper ladies did not talk that way, and it was considered t

Det huvudsakliga syftet med denna uppsats är att undersöka om ett fullgott juridiskt ramverk i syfte att skydda den arktiska regionen redan är etablerat, eller om ytterligare juridiska instrument behöver tillkomma för att så ska vara fallet. Frågan diskuteras med bakgrund av det faktum att den arktiska isen smälter i en hög takt, och att framtiden för regionen sannolikt kommer att se väldigt annorThe main purpose of this thesis is to examine whether or not the legal framework to govern the Arctic can be said to be in place already, or if additional judicial measures need to be taken, given the future that awaits the region as a result of the ongoing rapid ice melt. For many decades, or even centuries, it was the common perception that the Arctic would remain permanently ice-covered, and be
