With increasing pressures to reduce greenhouse gas emissions, heavy-duty freight is moving to electrification, but this shift remains challenging due to high energy demand, long operating hours, strict delivery schedules, and limited tolerance for charging downtime. This thesis examines whether battery swapping combined with Battery-as-a-Service can contribute to the sustainability transition of h
The COST2100 channel model is a reference channel model which provides dynamic multiple-input multiple-output channel responses for radio system simulations. In this paper, channels created by the COST2100 model were compared to channel measurements in order to understand behaviours of the model. Model parameters of the COST2100 model were derived by dynamic double-directional channel measurements
Coordinated Multi Point (CoMP) transmission and reception techniques are used in order to improve the performance of single or multiple cells in wireless systems. A system using CoMP techniques is capable of jointly optimizing its transmission and/or reception and, hence, achieving higher performance. In this work, performance evaluation of three CoMP techniques are performed based on simulations
This thesis explores the long-term viability of integrating Boat-to-Grid (B2G) systems into electric marine vessels, considering technical reliability, environmental impact, and economic feasibility. Through degradation modeling, simulation-based analysis, lifecycle assessment, and financial modeling within the context of Göteborg, Sweden, this work offers a framework to understand how electric bo
To enable realistic studies of massive multiple-input multiple-output systems, the COST 2100 channel model is extended based on measurements. First, the concept of a base station-side visibility region (BS-VR) is proposed to model the appearance and disappearance of clusters when using a physically-large array. We find that BS-VR lifetimes are exponentially distributed, and that the number of BS-V
Research has been pointing out that productivity in the building industry is stagnant and in some cases declining. Poor productivity of craftsmen is one of the causes of cost and time overruns on building projects. Productivity of labour is particularly important especially in developing countries where most of the building work is still carried out on manual basis. The objective of this research
The control of the Touch Hand: a low-cost electrically powered prosthetic hand is explored in this paper. A novel Haptic User Interface is proposed and tested as a supplement for amputee-prosthetic EMG control. The performance of the prosthetic hand is tested through gripping tests. The hand is capable of performing a lateral grip of 3.7 N, a power grip of 19.5 N and to passively hold a weight of
The purpose of this thesis is to estimate the costs associated with hand injuries inflicted by log splitters and circular saws, and by doing this also estimate a value of prevention. This is carried out in the form of a cost of illness study with an incidence approach. A consecutive data material comprising 57 patients was obtained from the Department of Hand Surgery at Malmö University Hospital (
To estimate current and future avoidable smoking-attributable costs in Sweden for the year 2007.
The cost of ownership of a power plant is partly governed by the efficiency of the turbine island. The turbine stands for the production revenues when transforming the energy in fuel into electric power and district heating. One gauge of the quality of the individual processes is the component efficiency - the current work addresses the turbine part of the power plant. The turbine efficiency is d
ObjectivesThe main objective of this study was to derive cost estimates of five major foodborne illnesses (campylobacteriosis, salmonellosis, enterohemorrhagic Escherichia coli (EHEC), yersiniosis and shigellosis) in Sweden. These estimates provide a necessary contribution to perform future cost-benefit analyses aimed at reducing the burden of foodborne disease. A secondary aim was to obtain estim
OBJECTIVE: To determine costs of illness for adult diabetes mellitus (DM), including complications caused by DM. DESIGN: A population-based multicentre cross- sectional study including an interview and a physical examination of patients identified as having DM. The patients' medical records were analysed regarding diagnoses and complications attributable to DM. SETTING: Eight health care centres o
3G networks and services are being launched all over the world. The basic investments on equipment have already been made according to preliminary traffic forecasts. However, if the mobile data traffic acquires "Internet-like" proportions, network capacity shortage will become a reality in densely populated areas, such as city centers and business parks. In that case, smart antennas may be the sol
The pervasive use and insatiable demand for high-performance wireless devices globally are driving the development of new communication technologies and standards. In this chapter, we present advancements in the area of terminal antenna systems and describe how they play a major role in enabling strict performance requirements to be met in future systems. As opposed to conventional systems that do
This paper examines the relationship between credit ratings and aggregate, as well as individual pillar CSR scores during the periods of 2009 and 2014 for European corporations. The results indicate that the aggregate CSR scores did not influence credit ratings for either period. However, social pillar scores had a statistically significant impact on credit ratings during the financial crisis of 2
This paper aims to explore if theory from the literature on Social Democratic parties can account plausibly for relatively better election results of the Swedish Social Democrats (SAP). With the use of multiple OLS regression it explores whether expansion of municipal labor decommodifying programs lead to more favorable municipal election results for SAP. Labor decommodification is measured throug
Power-to-X (PtX) is an emerging approach in decarbonizing industries hard to electrify, and is in many cases requiring stable hydrogen supply to maximize production. Hydrogen is produced via electrolysis and requires large amounts of electricity, which can be expensive, especially when considering highly fluctuating electricity prices. One solution in reducing electricity related costs is to integ
