There are increasing concerns over building code, regulation compliance, and quality assurance issues in adopting off-site construction techniques the industry related to meeting client expectations regulatory requirements. Performance-based regulations often allow for space innovation but not a safe those who intend introduce new prescribed regulations. Through series of surveys conducted Swed...

Construction sites grinds out deep noises, mostly from vehicles, equipment and array of machineries. Surplus noise is not only infuriating and diversionary, but can lead to hard of hearing, blood pressure, sleeping trouble and awful stress. High noise levels in construction escalate the nature and environment. Among various pollutions noise pollution from construction industry is one of the imp...

This paper presents an optimization approach for estimating the 3D parameters of buildings from multiple images by fitting the observations to the geometric building models. Through multi-image traingulation, the coordinates of the building corners and their covariances are estimated from the located image corresponding points. Then by a constrained optimization the estimated point positions an...

Protein phosphorylation is one of the most pervasive post-translational modifications, regulating diverse cellular processes in various organisms. As mass spectrometry-based experimental approaches for identifying phosphorylation events are resource-intensive, many computational methods have been proposed, in which phosphorylation site prediction is formulated as a classification problem. They ...

A computer program is described which constructs maps of restriction endonuclease cleavage sites in DNA molecules, given only the fragment lengths. The program utilizes fragment length data from single and double restriction enzyme digests to generate maps for linear or circular molecules. The search for a map can be limited to the unknown (insert) region of a recombinant phage or plasmid. Typi...

The NIST Construction Metrology and Automation Group (CMAG), in cooperation with the NIST Intelligent Systems Division (ISD), is developing performance metrics and researching issues related to the design and development of a "Next Generation LADAR" sensor that will enable general automation in structured and unstructured environments. This paper quickly reviews the basic physics and implementa...

In the planning phase of every construction project, layout of temporary facilities is a crucial task; site layout can affect safety, travel cost and time, construction productivity, and space utilization. However, site layout planning can be a complicated problem, due to the interdependency of influencing factors. Although interaction among activities is one of the major drivers of site layout...

In UK's construction industry, site dumpers cause more serious accidents than in any other type of construction plant. Previous research has indicated that driver behaviour plays a pivotal role in the vast majority of these accidents. Using a mental models-based approach, 20 dumper drivers were interviewed with regard to the process by which several typical types of accident occurred. It was fo...
