Construction quality associated with the life of construction enterprises. Risk assessment of construction quality referred to a comprehensive evaluation of the degree of risk confronting construction units during the construction process. Construction units provide a decision-making basis for employers and supervisors, who considered the evaluations of construction quality and accidents in the...

driven precast reinforced concrete piles (dprcp) is extensively used as a foundation for bridges constructed over canals in egypt in order to avoid the diversion of water canals. the objectives of this research include identifying the main activities of dprcp execution in the bridge-construction industry in egypt and the risk factors affecting them. in addition, assessment of the effects of the...

Mobile Crowd Sensing (MCS) is a new paradigm which takes advantage of pervasive smartphones to efficiently collect data, enabling numerous novel applications. To achieve good service quality for a MCS application, incentive mechanisms are necessary to attract more user participation. Most of existing mechanisms apply only for the offline scenario where all users’ information are known a priori....

Proliferating Mobile Crowdsensing Systems (MCSs) is a promising paradigm to realize large-scale sensing targets in an agile and economical manner. Privacy protection mechanisms, which alleviate mobile user’s concern on participating MCS tasks, also introduce the issue of data quality to the MCS server. In privacy-preserving MCSs, dishonest reporting of mobile sensing data from task participants...
