Video moment retrieval targets at retrieving a golden in video for given natural language query. The main challenges of this task include 1) the requirement accurately localizing (i.e., start time and end of) relevant an untrimmed stream, 2) bridging semantic gap between textual query contents. To tackle those problems, early approaches adopt sliding window or uniform sampling to collect clips ...

One of the methods for retrofitting reinforced concrete moment frames is the use of steel braces. In this research, the seismic performance of a double-skinned concrete framing system reinforced with two concentric (CBF) and eccentric (EBF) steel bracing, was investigated under seven near-fault earthquake records of varying intensity. For this purpose, two ten-story concrete frames with five sp...

In this paper we present a novel computational approach to predict the overall hyperelastic mechanical properties of ultralight cuboct cellular lattices made of brittle carbon fiber-reinforced polymer composites, such as the ones recently fabricated at the MIT Media Lab-Center for Bits and Atoms. These architected cellular composites, by combining both the specific features of composite materia...

A probabilistic frame is a Borel probability measure with finite second moment whose support spans R. A Parseval probabilistic frame is one for which the associated matrix of second moment is the identity matrix in R. Each probabilistic frame is canonically associated to a Parseval probabilistic frame. In this paper, we show that this canonical Parseval probabilistic frame is the closest Parsev...

BACKGROUND changes in lower-limb joint moments are important outcome measures for treatment and prevention of knee osteoarthritis. However, it is known that both the magnitude and amplitude of joint moments are affected by the choice of anatomical reference frame. The purpose of this study was to identify features of joint moment waveforms that, regardless of the choice of reference frame, are ...

The k-truss is a type of cohesive subgraphs proposed recently for the study of networks. While the problem of computing most cohesive subgraphs is NP-hard, there exists a polynomial time algorithm for computing k-truss. Compared with k-core which is also efficient to compute, k-truss represents the “core” of a k-core that keeps the key information of, while filtering out less important informat...

To study the fatigue performance of a composite girder with corrugated steel web (CSW) and tube (ST) truss, based on an engineering object, test finite element (FE) analysis were carried out. The failure mode sensitivities hot spot stress to geometric parameters above studied. position maximum crack discussed determined. Furthermore, life evaluation method was discussed. It found that linear ex...

A computational model is presented for determining deformations in complexly stressed beams of a structurally non-linear reinforced concrete frame transcendental state caused by special emergency action the form sudden removal one structural elements. The determination stress-strain after formation spatial cracks elements was carried out using calculated section. At same time, dynamic additiona...

Imperfection sensitivity properties are derived for finite dimensional elastic conservative systems exhibiting hill-top branching at which arbitrary many bifurcation points coincide with a limit point. The critical load at a hill-top branching point is demonstrated to be insensitive to initial imperfections when all the bifurcation points are individually symmetric. Therefore, it is not dangero...

In recent years, with the development of high-strength steel materials and improvements in welding technology, has been widely used structure. Nagoya Zokei University Art & Design project, 40m trusses is designed, 100mm thick TMCP440 was for diagonal members. The erection plan required on-site welded joints at ends diagonals, ensuring quality welds a major construction management issue. Therefo...
