Abstract (sommario):
We address the problem of retrieving a specific moment from an untrimmed video by a query sentence. This is a challenging problem because a target moment may take place in relations to other temporal moments in the untrimmed video. Existing methods cannot tackle this challenge well since they consider temporal moments individually and neglect the temporal dependencies. In this paper, we model the temporal relations between video moments by a two-dimensional map, where one dimension indicates the starting time of a moment and the other indicates the end time. This 2D temporal map can cover dive

Abstract (sommario):
Abstract If ω is a closed G-invariant 2-form and μ is a moment map, we obtain necessary and sufficient conditions for equivariant prequantizability that can be computed in terms of the moment map μ. Our main result is that G-equivariant prequantizability is related to the fact that the moment map μ should be quantized for certain vectors on the Lie algebra of G. We also compute the obstructions to lift the action of G to a prequantization bundle of ω. Our results are valid for any compact and connected Lie group G.

Abstract (sommario):
We consider a G-invariant star-product algebra A on a symplectic manifold (M,ω) obtained by a canonical construction of deformation quantization. Under assumptions of the classical Marsden-Weinstein theorem we define a reduction of the algebra A with respect to the G-action. The reduced algebra turns out to be isomorphic to a canonical star-product algebra on the reduced phase space B. In other words, we show that the reduction commutes with the canonical G-invariant deformation quantization. A similar statement in the framework of geometric quantization is known as the Guillemin-Sternberg con

For loading of excavator drive units, it is necessary to use electromechanical loads with a high torque up to 16,000 Nm in a low speed range from 0 to 150 min-1 with a maximum output of 50 kW. The electromechanical load consists of an asynchronous dynamometer assembly with a tilting torque measurement system in conjunction with a front three-speed gearbox. The dynamometer is powered by a converter with vector control. To determine the torque at the gearbox output, a correction must be made and the influence of operating temperature and operating speed must be taken into account. Experimental m

Abstract (sommario):
This thesis is mainly concerned with the study of hypersymplectic structures in gauge theory. These structures arise via applications of the hypersymplectic quotient construction to the action of the gauge group on certain spaces of connections and Higgs fields. Motivated by Kobayashi-Hitchin correspondences in the case of hyperkähler moduli spaces, we first study the relationship between hypersymplectic, complex and paracomplex quotients in the spirit of Kirwan's work relating Kähler quotients to GIT quotients. We then study dimensional reductions of the ASD equations on $mathbb R^{2,2}$. We

This PhD is written in the context of the Curatorial/Knowledge programme at Goldsmiths College. It deals foremost with a conversation between art practice and the curatorial, where a thesis emerges as a consideration of art practice as more than just the work of an artist. In the context of the dissertation, art practice “stages” tensions between official, institutional and situated knowledge and knowledges that are unpredictable, unfixed, and uncontained — tensions that are at the heart of what is meant by “curatorial/knowledge. ” I make a distinction between the exhibition as a bracketed, te

Geometrically nonlinear finite element analysis is used to create the maps for compliant mechanisms consisting of slender beams. In addition to the topology and shape, the overall proportions and the proportions of the cross-sections of the beam segments are kept fixed

The results evidence that the lack of consensus with respect to how fouling proceeds is bond to yield engine performances that differ by large.

However, the microturbine was using an existing turbocharger rotor component with unknown margins. Therefore, the purpose of this paper is to perform both theoretical and experimental analyses of the dynamic characteristics of the 12-pound thrust microt

Abstract (sommario):
Map key international and national days, events, moments relating to Covid-19 (e.g. health, socio-economic, inclusion impacts) to inform Covid Collective’s schedule of publications and activities. Mapping should include: - UN/international days; - Global events, e.g. COP 26; - National days/key events in Covid Collective countries; - Key milestones, anniversaries tied to the pandemic.

Abstract (sommario):
The purpose of this report is to provide a set of ground motion models (GMMs) to be considered by the U.S. Geological Survey (USGS) for their National Seismic Hazard Maps (NSHMs) for the Central and Eastern U.S. (CEUS). These interim GMMs are adjusted and modified from a set of preliminary models developed as part of the Next Generation Attenuation for Central and Eastern North-America (CENA) project (NGA-East). The NGA-East objective was to develop a new ground-motion characterization (GMC) model for the CENA region. The GMC model consists of a set of GMMs for median and standard deviation of

Abstract (sommario):
Horizontality is a salient social phenomenon of the last decade. It asserts itself against hierarchies in social movements and countless other collective practices around the world. It constitutes a characteristic of an emergent sociality that demands the attention of the social sciences. The 2010s are a moment as important as “the Sixties”, a time when Ivan Illich called for the development of tools of conviviality, and horizontality may be categorized as one of them. Today’s horizontality may be related to that of populations that have been the focus of anthropologists interested in their lo

Abstract (sommario):
Studying earthquakes in Baffin Bay and the surrounding regions is challenging. There is no knowledge of earthquake activity in this region prior to 1933 when a moment magnitude (MW) 7.4 earthquake occurred in Baffin Bay. With improved instrumentation, increased seismograph coverage in the north, and modern analysis techniques, knowledge and understanding of earthquakes in the Baffin region is improving. Active seismic zones include Baffin Bay, the east coast of Baffin Island, and the Labrador Sea, separated by areas of low seismicity. Focal-mechanism solutions show a mix of faulting styles, pr

Abstract (sommario):
This document is the final project report of the Next Generation Attenuation for Central and Eastern North America (CENA) project (NGA-East). The NGA-East objective was to develop a new ground-motion characterization (GMC) model for the CENA region. The GMC model consists of a set of new ground-motion models (GMMs) for median and standard deviation of ground motions and their associated weights to be used with logic-trees in probabilistic seismic hazard analyses (PSHA).

Abstract (sommario):
This guideline and its associated software River-X present a methodology for the assessment of pipeline integrity under hydrodynamic loads and impact loads from floating or moving debris in the river. The software provides a numerical tool with a user-friendly interface for assessing the risk of pipeline failure following the principles outlined in this guideline. The River-X simulates sections of exposed pipeline including the anchoring in the embankment and plastic material behavior for 2 basically different scenarios; an exposed pipeline on/in riverbed and a free spanning pipeline.
