Although it has been widely discussed in video surveillance, background subtraction is still an open problem in the context of complex scenarios, e.g., dynamic backgrounds, illumination variations, and indistinctive foreground objects. To address these challenges, we propose a simple yet effective background subtraction method that learns and maintains dynamic texture models within spatio-tempo...

A brick is a 3-connected graph such that the graph obtained from it by deleting any two distinct vertices has a perfect matching. Bricks are building blocks of the matching decomposition procedure of Kotzig, Lovasz and Plummer, and therefore many matching-related problems can be reduced to bricks. We prove, roughly, that every brick other than the Petersen graph can be generated from a “matchin...

Soft, 3D elastomeric structures and composite structures are easy to fabricate using click-e-bricks, and the internal architecture of these structures together with the capabilities built into the bricks themselves provide mechanical, optical, electrical, and fluidic functions.

Companies and government ministries alike have been rapidly shifting from the brick-andmortar to the brick-and-click business model following the tremendous improvements in telecommunications infrastructure, coupled with the ever increasing competitiveness and global influences in local industries. Security unquestionably plays a pivotal role in any online presence. Websites that are built and ...

A large number of researchers have studied the behavior of infilled frames. It is evident through their studies that infill walls can provide both an economic and practical means for the lateral stability of framed structures and a viable alternative for retrofitting existing structures to resist seismic, wind, and blast loads. Despite this, there is reluctance from the engineering community to...

XML retrieval, also referred to as Structured Document Retrieval is a discipline of information retrieval that focusses on the retrieval of relevant document fragments for a given information need that contains both structural and textual components. In this article we will focus on the theory behind Bricks, a visual query formulation technique for XML retrieval that aims at reducing the comple...

The paper deals with the application of combined nondestructive method for assessment of compressive strength of calcium silicate bricks. In this case, it is a combination of the rebound hammer method and ultrasonic pulse method. Calibration relationships for determining compressive strength of calcium silicate bricks obtained from nondestructive parameter testing for the combined method as wel...

We describe a simple and robust method to construct complex three-dimensional (3D) structures by using short synthetic DNA strands that we call "DNA bricks." In one-step annealing reactions, bricks with hundreds of distinct sequences self-assemble into prescribed 3D shapes. Each 32-nucleotide brick is a modular component; it binds to four local neighbors and can be removed or added independentl...

in this paper, nonlinear behavior of composite steel plate shear wall systems, in which steel infill plate is strengthened by fiber reinforced polymer (frp) layers, are experimentally investigated. tests are designed to evaluate the effect of glass-frp layers, layers number of gfrp and orientation of gfrp layers on the stiffness, shear strength, cumulative dissipated energy and other seismic pa...
