This paper contributes to semantic representation of human demonstrated actions for robot execution of time constrained tasks. We propose a semantic action encoding method based on interactions between the subject and objects in the scene. Our semantic framework is enriched with a descriptive spatial reasoning method which leads to accurate segmentation and recognition of unique action primitives.
Understanding continuous human actions is a non-trivial but important problem in computer vision. Although there exists a large corpus of work in the recognition of action sequences, most approaches suffer from problems relating to vast variations in motions, action combinations, and scene contexts. In this paper, we introduce a novel method for semantic segmentation and recognition of long and co
We present a novel unsupervised framework, which links continuous visual features and symbolic textual descriptions of manipulation activity videos. First, we extract the semantic representation of visually observed manipulations by applying a bottom-up approach to the continuous image streams. We then employ a rule-based reasoning to link visual and linguistic inputs. The proposed framework allow
Dogs exhibit an exceptional range of morphological diversity as a result of their long-term association with humans. Attempts to identify when dog morphological variation began to expand have been constrained by the limited number of Pleistocene specimens, the fragmentary nature of remains, and difficulties in distinguishing early dogs from wolves on the basis of skeletal morphology. In this study
BACKGROUND: Shiga toxin (Stx) is the main virulence factor of enterohemorrhagic Escherichia coli, a food-borne pathogen that colonizes the intestine causing gastroenteritis and, in severe cases, hemolytic uremic syndrome. Stx was shown to induce ATP release in vivo and in vitro and blockade of purinergic P2X receptors inhibited its cytotoxicity. Here we investigated the intracellular signaling eve
With a significant impact on turbomachinery blade performance, surface curvature distribution becomes one of the essential factors in the design of high-efficiency blades. This study focuses on applying computational fluid dynamics (CFD) to evaluate turbine rotor blade performance. The main aim is to analyze the influence of incidence and geometry shape on the performance of a gas-turbine blade in
In this work, we present a new single-stage method for subject agnostic face swapping and identity transfer, named FaceDancer. We have two major contributions: Adaptive Feature Fusion Attention (AFFA) and Interpreted Feature Similarity Regularization (IFSR). The AFFA module is embedded in the decoder and adaptively learns to fuse attribute features and features conditioned on identity information
This chapter is an exploration of the concept of periphery when applied to regions. Specifically, it unpacks what we mean when we talk about places, specifically regions, as “peripheral”. It does this from the perspective of a sub-discipline of human geography: regional economic geography. In this field, peripheral regions are becoming increasingly interesting to researchers due to their key roles
Regional studies often treat the region as a sub‑national unit, and it spans from neighbourhoods to cross‑border macro‑regions. In Asia, this elasticity is intensified by language. Words that look equivalent on paper rarely carry identical histories, politics, or scales. This short piece reflects on the Chinese notion of quyu (区域) and how it travels between domestic and international contexts, see
Quantitative laser-based diagnostics like Raman spectroscopy are essential for studying high-temperature processes, but their application in intensely luminous and transient environments such as plasma torches is severely limited by overwhelming background emission. This study focuses on the quantitative thermometry of a 7 kW atmospheric air plasma jet, an environment where such measurements are n
This guidebook offers practice‑oriented guidance for initiating, developing, and sustaining collaborative housing projects across Europe. Building on the EU‑funded CO‑HOPE (Collaborative Housing in a Pandemic Era) research project and its Urban Living Lab, it synthesizes insights from the planning processes of studied collaborative housing initiatives. Grounded in participatory workshops with resi
A numerical and experimental study of partial admission in a low reaction two-stage axial air test turbine is performed in this paper. In order to model one part load configuration, corresponding to zero flow in one of the admission arcs, the inlet was blocked at one segmental arc, at the leading edge of the first stage guide vanes. Due to the unsymmetrical geometry, the full annulus of the turbin
Darknet framställs ofta som en digital värld präglad av avvikelse och kriminalitet – en plats där ”allt är tillåtet” och som därför anses kräva övervakning och kontroll. Trots detta är kryptoforum fortfarande relativt understuderade. Med utgångspunkt i tre års etnografiskt fältarbete ger denna avhandling nya insikter i de interna dynamikerna i en till stor del dold onlinegemenskap. Genom att kombiThe Darknet is often portrayed as an online realm marked by deviance and criminality – a space where “anything goes” and therefore requires policing. Yet its cryptoforums remain comparatively understudied. Drawing on three years of ethnographic fieldwork, this dissertation provides new insights into the internal dynamics of a largely hidden online community. Combining digital observations with 19
Despite a wealth of sophisticated CFD-methods, most designs are still based on one-dimensional and two-dimensional inviscid analytical tools. In such methods, realistic loss and angle assessment are indeed critical in order to arrive at correct loading, flow coefficient and reaction. The selected values are normally retained through the detailed design sequence for each iteration. This means that
In this article, we use a crowd theoretical perspective to look at student crowds and how they have been managed through various subdivisions of student housing. How has the student cohort been territorialised and divided into entities according to differences in group sizes, gender, family constellations, etc., and how has housing played a role in these social differentiations? Using the history
In medieval Scandinavia, parchment was a crucial writing material for everything from property deeds and judicial matters to religious works and account keeping. As society became more and more invested in literacy, the demand for parchment grew. However, the supply of animals for parchment could not increase to the same extent without great changes in animal husbandry. This thesis explores how me
In this work, numerical analysis was performed to predict the behaviour of high Reynolds number turbulent cross-flows used in film cooling applications. The geometry included one row of three discrete coolant holes inclined at 30 degrees to the main flow. In the computational model, the width of the channel was cut into one sixth and symmetry boundaries were applied in the centreline of the coolan
Possession of flowers that trap fly pollinators is a conservative trait within the genus Ceropegia, in which pollination systems can be generalized or highly specialized. However, little is known about the role of plant–pollinator interactions in the maintenance of species boundaries. This study examined the degree of plant–pollinator specialization and identified the parameters responsible for sp
A critical step during in vitro sexual propagation of terrestrial orchids is the treatment of the microscopic seeds with a disinfecting solution that kills bacteria and fungi attached to the seeds. This treatment is necessary to prevent infection of the culture vessels. At the same time, the treatment serves to scarify the seeds, a process that disrupts seed dormancy and initiates germination. The
