The monitoring and tracking of construction equipment, e.g., excavators, is great interest to improve the productivity, safety, sustainability projects. In recent years, digital technologies are leveraged develop systems for equipment. These commonly used detect and/or track different pieces However, research work has indicated that performance equipment system improves when they able also reco...

There are analytic methods for designing protective barriers however, they lack sufficient efficiency and considering the NCRP (National Council on Radiation Protection and measurements) reports, designing mechanical protective barrier in order to protect the initial x-ray radiation and absorption of the ray quality of such radiation is different. In this study, computer software was designed t...

Awkward postures during the oper­ ation of heavy construction equipment are a consequence of improper cab de­ sign and work procedures. Poor visi­ bility of the task, limited room in the cab, excessive forces required to operate levers/pedals, and improper seat designs are some of the characteristics of a poorly designed cab. If not controlled, awkward posture of any body part can result in in­...

Aiming at the characteristics which variable air volume air conditioning system is multi-variable, nonlinear and uncertain system, normal fuzzy neural network is hard to meet the requirements which dynamic control of multi-variable. In this paper, we put forward a recursive neural network predictive control strategy based on T-S fuzzy model. Through T-S fuzzy recursive neural network predictor ...

Relative to coal fired and natural gas fired power plants, nuclear power plants are more expensive to build but less expensive to run. This annex describes advanced construction methods to reduce nuclear power's construction costs, mainly by shortening the time needed to build a plant. Each of the methods described below has been used in one or more of the projects listed in Table IV-1. None is...

The objective of this study was to determine whether the 4 pieces of equipment for cutting moulding, cutting reinforcement rods, carrying carpet rolls, and fitting drain pipes can lighten the work load of construction work. The results indicate that the effect of using the new ergonomically designed equipment was positive. The cutter for reinforcement rods proved to be useful, bent back posture...

This paper purports to provide answers to the following questions with regard to multi-crane building construction sites: (1) Do such construction sites differ from smaller sites only in magnitude, or are there unique characteristics that stem from the size of the site and the multitude of cranes? (2) Is equipment planning for such projects similar to that of projects serviced by a small number...
