This appendix presents additional discussion on several aspects of the proposed algorithm. Sec. A presents a modification of our algorithm which enables users to reflect local connectivity in link prediction. The remaining sections focus on the label propagation application. Sec. B and C discuss functionalities of active label acquisition and adding new images to the match graph while Sec. D di...
The aim of this research is to examine the market potential for wood plastic composite (WPC) products in the highway construction sector in place of nonrenewable materials (e.g. virgin plastic and steel) and preservative-based products (treated wood). State-level transportation officials indicate that the majority of highway construction purchases are conducted by highway construction contracto...
As the premier material in construction industry across the world, concrete has major role in the effects of construction to our environment. Consumption of concrete is very high due to extensive use of concrete in many structural applications. The rapid infrastructural growth in developing countries and production of many by-product as waste material making high role to concrete producers in i...
Current approaches in planning building site equipment evaluate static periods, e.g. construction phases. As a consequence these states provide a rudimentary optimized layout plan, however without considering the material flow and corresponding interactions in a precise form. Due to dynamic processes, which could obstruct the material flow, an adaption of the equipment layout during individual ...
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
One of the most frequently corrosion type is the atmospheric corrosion. Carbon steel behavior at atmospheric corrosion is presented on base of the literature data study. This has been reported to account for more failures in terms of cost and tonnage than any other type. About 80% from all degradations produced by corrosion in the metallic constructions are due to the atmospheric corrosion. The...
Introduction: Nearly half of occupational accidents in Iran occur in construction sites. Therefore, modeling of occupational accidents in these sites is one of the solutions to design safety strategies to reduce occupational accidents in the field of construction. This study was designed and conducted with the aim of modeling the cause-consequence of accidents in construction sites. Material a...
concrete is one of the most widely used materials in construction industry. many large and important structures such as power plants, bridges, dams and buildings employ concrete as main material. propagation of crack is considered one of the main reasons in failure of concrete structures. the process of formation and crack growth is one of the major and complex issues in concrete, because concr...
Polymer-cement composites (PCCs) are materials in which the polymer and mineral binder create an interpenetrating network and co-operate, significantly improving the performance of the material. On the other hand, the need for the utilization of waste materials is a demand of sustainable construction. Various mineral powders, such as fly ash or blast-furnace slag, are successfully used for the ...
