A sports video analysis application was developed by Spiideo for mobile devices. It presents recordings from practices and competitive games for game-play analysis. Available tools, such as on-screen drawings, require a robust background foreground segmentation. The currently used segmentation method have difficulties to master the shifting conditions in weather, shadows and shirt colors. The pu
Like many engineering programs in Europe, the final part of most Swedish software engineering programs is a longer project in which the students write a Master's thesis. These projects are often conducted in cooperation between a university and industry, and the students often have two supervisors, one at the university and one in industry. In particular, the Bologna Process that is currently unde
Conflict-driven pseudo-Boolean solvers optimize 0-1 integer linear programs by extending the conflict-driven clause learning (CDCL) paradigm from SAT solving. Though pseudo-Boolean solvers have the potential to be exponentially more efficient than CDCL solvers in theory, in practice they can sometimes get hopelessly stuck even when the linear programming (LP) relaxation is infeasible over the real
Control of network systems with uncertain local dynamics has remained an open problem for a long time. In this paper, a distributed minimax adaptive control algorithm is proposed for such networks whose local dynamics has an uncertain parameter possibly taking finite number of values. To hedge against this uncertainty, each node in the network collects the historical data of its neighbouring nodes
We study dynamics in a network of interacting agents updating their binary states according to a time-varying threshold rule. Specifically, agents revise their state asynchronously by comparing the weighted average of the current states of their neighbors in the interaction network with possibly heterogeneous time-varying threshold values. Such thresholds are determined by an exogenous signal repr
Cooperative transmission by base stations (BSs) can significantly improve the spectral efficiency of multiuser, multicell, multiple input multiple output (MIMO) systems. We show that contrary to what is often assumed in the literature, the multiuser interference in such systems is fundamentally asynchronous. Intuitively, perfect timing-advance mechanisms can at best only ensure that the desired si
Abstract in UndeterminedSignal detection algorithms providing likelihood informationfor coded spatial-multiplexing multiple-input multipleoutput(MIMO) wireless communication system pose a criticaldesign challenge due to their prohibitively high computationalcomplexity. In this paper, we present a low-complexity soft-outputdetection algorithm by adopting four implementation-friendlyalgorithm-level
In this article, we describe a system that classifies relations between entities extracted from an image. We started from the idea that we could utilize lexical and semantic information from text associated with the image, such as captions or surrounding text, rather than just the geometric and visual characteristics of the entities found in the image. We collected a corpus of images from Wikipedi
Low-Power Wide-Area Networks operating in the unlicensed bands are being deployed to connect a rapidly growing number of Internet-of-Things devices. While the unlicensed sub-GHz band offers favorable propagation for long-range connections, measurements show that the energy consumption of the nodes is still mostly dominated by the wireless transmission affecting their autonomy. We investigate the p
A novel low-complexity detection scheme is proposed for the multiple-input multiple-output (MIMO) single-carrier frequency division-multiple access (SC-FDMA) systems, which is suitable for ASIC implementations. The proposed detection scheme makes an initial estimate of the transmitted signal based on a minimum mean square error (MMSE) frequency domain equalizer (FDE) detector and finds symbols wit
Pseudo-random functions are a fundamental building block in many cryptographic applications. In certain scenarios, a weaker notion (where security is restricted to uniformly random input), but more computationally efficient, called weak pseudo-random functions, is sufficient. In this work, we present new differential attacks on the main binary weak pseudo-random function constructions, namely the
We apply the statistical sparse jump model, a recently developed, interpretable and robust regime-switching model, to infer key features that drive the return dynamics of the largest cryptocurrencies. The algorithm jointly performs feature selection, parameter estimation, and state classification. Our large set of candidate features are based on cryptocurrency, sentiment and financial market-based
When creating models of a system, there is always a tradeoff between the ease of modelling a part and the increased value it brings to the model. Learning a model using machine learning instead, we are able to capture all kinds of things we don't necessarily understand, but can need large amounts of data to learn even the things we find simple. Using universal differential equations we can combine
Højesteret frågade domstolen i Europeiska Unions om förhandsavgörande i fallet om Post Danmarks hade missbrukat sin dominerande ställning med tolkning under artikel 102 i funktionsfördraget. Post Danmark hade tillämpat prisstrategier som förvärvats synergier som upprätthålls av sitt utbud av flera produkter. Post Danmark har kunnat tvinga ned priserna på den relevanta marknaden för oadresserade brHøjesteret asked the Court of Justice of the European Unions for a preliminary ruling of the situation of Post Danmark abusive dominant position under article 102 TFEU. Post Danmark had applied price strategies acquired from synergies maintained from its range of products. Post Danmark was able to force prices down on the relevant market for unaddressed mail in the market of Denmark. The pricing h
1 ‘The World Turned Upside Down’: art and ethics in the rise of the ‘Stone Age South’ The thrust of today’s migrations seems largely ‘Northward’—even in the Antipodes where they are clearly headed towards the opposite pole. The ‘South’ has tended to signal ‘underdevelopment and crisis ’. But it has also flagged up notions of ‘other possibilities, alternative perspectives’, other ‘designs for livin

EG har kontinuerligt ägnat sig åt reglering av kemiska produkter. 1967 antogs första rättsakten som rörde kemikaliekontroll. Under 1960- och 70-talen antogs gemenskapslagstiftning främst för att undanröja hinder för den gemensamma inre marknaden och därmed främja den fria varurörligheten. Under 1980-talet blev miljöskydd ensamt skäl att anta lagstiftning på kemikalieområdet. Genom åren har ett ant
Johnson Matthey Formox är ett företag som designar och säljer fabriker för produktion av kemikalien formaldehyd. Företaget tillverkar även katalysatorer för detta ändamål. För att erbjuda en bra och konkurrenskraftig produkt till sina kunder är företaget måna om att processen skall vara effektiv och framförallt kostnadseffektiv. En del i detta är att kartlägga hur vatten påverkar produktionen av fThis diploma work has been performed in collaboration with Johnson Matthey, a company supplying catalysts and technologies, such as formaldehyde plants and catalysts. The aim of the master thesis project was to investigate if and how water impacts the partial oxidation of methanol to formaldehyde over a FeMo-catalyst. The investigation covers how water affects the selectivity to the main product a
The active site of the [FeFe] hydrogenases contains two Fe ions bound to one Cys ligand, three CO molecules, two CN(-) ions, and a dithiolate ligand. The nature of the last of these has been much discussed, and it has been suggested that it contains C, N, or O as the bridgehead atom. Most experimental studies indicate a N atom, whereas a recent density functional theory (DFT) study of a crystal st
Poor public perception can obstruct a construction project in a damaging way. Knowledge about public opinion should be considered as a relevant area of expertise for project managers and as an essential cost element in the planning and completion of construction projects. A consensual approach to a siting controversy requires informal face-to-face interaction among chosen representatives from all
This study describes the chydorid (Branchiopoda, Anomopoda) assemblages from 66 European shallow lakes, and presents data relating the assemblages to lake type and ecological quality. Forty species, out of a total recorded European fauna of 60 species, were found in the study sites. No significant differences were found between chydorid assemblages associated with rock and plant substrata. Pattern
