Many countries have increased the use of renewable energy and strongly promoted offshore wind power (OWP). However, OWP in Asia is preliminary stage development, for which no precedents exist. The literature on generation has mostly investigated causes onshore turbine accidents risk prevention, more work risks associated with domestic required market development. According to statistics interna...

Lean production theory, as a production management tool, describes a system that delivers a finished product free from defects, to a customer in zero time, and with nothing left in inventory. Recently, the concepts of lean production have been introduced to construction yet have generally been rejected. Lean construction concepts were recently tested in a simulation environment and were found t...

The construction industry is always looking for new, creative ways to increase the effectiveness and precision of its operations. use drones cut-and-fill operations in one area where great progress has been made. Construction sites are now being surveyed by order gather data analysis decision-making. In this paper, we examine usage cut fill how they might be used conjunction with aerial analyti...

Efficiency multipliers for construction productivity are often estimated on an ad-hoc basis, depending on the project characteristics. The purpose of the study is to define a structured approach allowing the determination of the appropriate empirical productivity relations and efficiency multipliers along with their respective values. The proposed method breaks down a given construction activit...

Universal hashes are usually based on some multivariate polynomials in message and key blocks (elements of some underlying ring R). These are implemented by using multiplications (which dominates the computational time) and additions. Two such hashes are pseudo dotproduct (PDP) hash and Bernstein-Rabin-Winograd (BRW) hash which require n/2 multiplications for n message blocks. In this paper we ...

Easydrawer is a graphical computer application which helps users to draw 2D constructions as they would do on a sheet of paper using a pair of compasses, a ruler and a pen. Easydrawer can significantly increase the productivity of geometrical drawers and help in making the construction process transparent to persons who are currently trained in technical drawing. The application comes with some...
