Environmental pollution is considered to be one of the main concerns in the construction industry. Environmental pollution has become a major challenge to construction projects due to the huge amount of pollution caused by construction projects. There are different types of environmental impact indicators, such as the greenhouse gas (GHG) footprint, eutrophication potential (EP), acidification ...

Received: June 06, 2017 Revised: July 05, 2017 Accepted: July 19, 2017 Abstract: Introduction: The use of polymer wastes in pavement as road is an increasing trend in the road construction sector. Those new pavements reduce the amount of solid waste disposed into landfills and provide more sustainable construction due to the use of in-situ materials. Polyurethane foam waste is a thermostable po...

This paper will present a knowledge layer used by a hierarchical on-road driving planner that represents a road network as a discrete set of attributed road states. This knowledge layer facilitates the construction of a planning graph by providing simulation and prediction services to the planning system. These services allow the determination of possible spatial transitions along a road networ...

BACKGROUND The human tissue kallikrein gene family, located at chromosome 19q13.4, is the largest contiguous family of proteases in the human genome. The locus encodes all 15 members of the family, 13 of which have been reported as potential biomarkers for several carcinomas and other non-neoplastic diseases. Kallikreins are expressed by a wide range of tissues and implicated in a number of phy...

Turbidity and suspended-sediment changes from stream-crossing construction on a forest haul road in West Virginia, USA" (2013). USDA Forest Service / UNL Faculty Publications. Paper 247. A forested headwater watershed in West Virginia was monitored to examine changes to in-stream turbidity following the construction of a 0.92 km (0.57 mi) haul road. Due to the design of the study, most of the s...

With the increasing traffic contradiction between supply and demand, urban traffic problems have become quite complex. Reasons for traffic congestion have become much more diverse. During the construction of urban road project, the surrounding road network will encounter a huge impact, traffic problems therefore emerged. Simulation is an important means for transport impact assessment, which ha...

This paper presents MODEST, aMethOD to hElp System Testing. MODEST can reduce the overall e ort required during software construction, using an extended design speci cation produced in a UPlike software process. This speci cation is used to automate test generation and execution, decreasing the e ort required during test activities. The method deals with Information Systems that follow an archi...
