[Background] The game industry faces fierce competition and games are developed on short deadlines and tight budgets. Continuously testing and experimenting with new ideas and features is essential in validating and guiding development toward market viability and success. Such continuous experimentation (CE) requires user data, which is often limited in early development stages. This challenge is

Market forces and legislation push the recovery of used material as part of developing a sustainable society. Materials made of forest fibres have the advantage compared to other materials that they are easy to recycle. It saves resources. Production of paper based on used fibres uses also less energy than paper containing new fibres. The market focus on recovery makes it a reasonable assumption,

In this work we study the problem of constructing precoders for spatially multiplexed multiple-input multiple output (MIMO) channels with close to optimal minimum Euclidean distance. In order to exploit the full potential of such designs, an ML detector must be used. Our design takes the decoding complexity into account and constrain it to a reasonable level. For our simplest case, the ML det

Quality of the polymer product produced by injection molding process are strongly affected by the mechanical properties of the skin-core structure formed during injection molding operation. It is desirable to know the mechanisms of the skin-core structure and the influence from process parameters and material properties to the skin-core formation in the injection molding. This paper focuses on cha

WLANs based on IEEE 802.11 are becoming more and more popular both in commercial and residential settings. However, the very success of 802.11 may become a threat to the technology itself. Since there are only a limited number of non-overlapping channels available in the IEEE 802.11 WLAN standards, this can lead to interference among WLANs in dense areas. In this paper, we investigate the effects

The design of radio-frequency inductively-degenerated CMOS low-noise-amplifiers does not follow the guidelines for minimum noise figure. Nonetheless, state-of-the-art implementations achieve noise figure values very close to the theoretical minimum. In this brief contribution, we point out that this is due to the effect of the parasitic overlap capacitances in the MOS device acting as transconduct

This paper reports on a new type of spherical agarose chromatography particles characterized by two sets of pores, normal diffusion pores, characteristic of all agarose materials and very wide pores, so-called superpores or flow pores. These superpores allow part of the chromatographic flow to pass through each individual particle, which gives improved mass transfer, especially in situations where

This thesis examines how meanings of female body hair are constructed, negotiated, and contested within digital spaces in contemporary China, focusing on the #armpithairfreedom on Rednote. While existing research on body hair and digital feminism is largely grounded in Western contexts, this study addresses a critical gap by situating analysis within China’s culturally specific and platform-regula

All human practices are, ultimately, set and defined by limits; be they social, economic, physical, or environmental. Yet even in the face of such realities, practices which transgress the confines of possibility remain remarkably obdurate. This thesis addresses the issue of one such practice, i.e. the escalation of personal mobility across time and space which pushes above and beyond systemic bou

Glycerol formation is vital for reoxidation of nicotinamide adenine dinucleotide (reduced form; NADH) under anaerobic conditions and for the hyperosmotic stress response in the yeast Saccharomyces cerevisiae. However, relatively few studies have been made on hyperosmotic stress under anaerobic conditions. To study the combined effect of salt stress and anaerobic conditions, industrial and laborato

A polymer foil based array with 9 gold electrodes for chronic electrophysiological recordings in the CNS has been developed. A polymer, SU-8, is pattered using photolithography techniques used every day in micro fabrication. This is beneficial if the electrode would be manufactured on a large scale basis. The technique makes it easy to adapt the array to best fit the structure of interest at the t

The study describes extraction of extracellular polymeric substances (EPS) from sewage sludge by applying enzymes and enzymes combined with sodium tripolyphosphate (STPP). Additionally, a systematic study of two non-enzymatic extraction agents is described. The assessment of the released products is made by colorimetrical methods and polysaccharides/glycoconjugates identification by the interactio

We present a batch method for recovering Euclidian camera motion from sparse image data. The main purpose of the algorithm is to recover the motion parameters using as much of the available information and as few computational steps as possible. The algorithm thus places itself in the gap between factorisation schemes, which make use of all available information in the initial recovery step, and s

Much of the progress in astronomy follows imaging with improved resolution. In observing stars, current capabilities are only marginal in beginning to image the disks of a few, although many stars will appear as surface objects for baselines of hundreds of meters. Since atmospheric turbulence makes ground-based phase interferometry challenging for such long baselines, kilometric space telescope cl

The shielding at an accelerator-driven spallation neutron facility plays a critical role in the performance of the neutron scattering instruments, the overall safety, and the total cost of the facility. Accurate simulation of shielding components is thus key for the design of upcoming facilities, such as the European Spallation Source (ESS), currently in construction in Lund, Sweden. In this paper

IKEA is a product developing company, known for putting packaging and logistics issues at the top of its agenda. At IKEA, the product and the packaging are developed concurrently with the aim of lowering the total cost from the supplier to the customer. During the years 2002 to 2004, a pckaging redesign project was conducted at IKEA. The purpose of the project was to redesign the packaging for an

Research in service management and marketing has in the past decade highlighted the concept of value creation. In service organizations value creation is described as a process in which the customer uses a company's value proposition in a meaningful way. However, research has tended to ignore the contextual meaning, and few empirical studies have shown how context is relevant. Therefore, the aim o
