Automated action classification of construction workers and equipment from videos is a challenging problem that has a wide range of potential applications in construction. These applications include, but are not limited to, enabling rapid construction operation analysis and ergonomic studies. This research explores the potential of an emerging action analysis framework, Bag-of-Video-Feature-Wor...

This paper presents principles of designing multisegment mechanical system. Represented is a model of a single segment, its extension in form of a couple of segments and the final construction – a fragmentary and simplified silhouette of a human form named the biped. This paper describes procedure of construction of the biped’s digital model using Matlab package. It also discusses test run of a...

In January 2017, a large wind turbine blade was installed temporarily in a city square as a public artwork. At first sight, media photographs of the installation appeared to be fakes - the blade looks like it could not really be part of the scene. Close inspection of the object shows that its paradoxical visual appearance can be attributed to unconscious assumptions about object shape and light...

over the past years, lake water levels have decreased considerably by various factors and the subsequent emergence of salt plain has brought disastrous consequences that need an essential action. therefore, this study aimed to investigate the effects of drying up and increasing lake water salt and landsat satellite images were used during different time periods in 9 years. to identify the new a...

In this paper, we propose a new global routing methodology named SEGRoute, which is based on grid graph segmentation of the given routing problem. The SEGRouting methodology first divides the grid graph of the routing problem into various segments; it then performs routing for the various segments (completing routing if possible and trying to maintain minimum wirelength) and then performs a “se...

We consider the problem of digitalizing Euclidean line segments from R to Z. Christ et al. (DCG, 2012) showed how to construct a set of consistent digital segment (CDS) for d = 2: a collection of segments connecting any two points in Z2 that satisfies the natural extension of the Euclidean axioms to Z. In this paper we study the construction of CDSs in higher dimensions. We show that any total ...

This paper describes the results of a study of the phonetic and phonological factors affecting the rhythm and timing of spoken Korean. Stepwise construction of a CART model was used to uncover the contribution and relative importance of phrasal, syllabic, and segmental contexts. The model was trained from a corpus of 671 read sentences, yielding 42,000 segments each annotated with 69 linguistic...

In order to improve the shortcomings of traditional constant section and gradual space elevator system, combined with advantages a model segmented system is designed. This has characteristics easier construction, more practical functions, maintenance. The cyclic iterative method proposed calculate stress distribution system. maximum variation scale different segment numbers analyzed compared re...
