Using nano-technology materials in the asphalt pavement industry is new compared with Portland cement concrete. The main objective of this study is to investigate the effects of nano-silica modification on some properties of a penetration grade asphalt cement and a typical asphalt concrete. 60/70 penetration grade bitumen was modified with different percentages of nano-silica (i.e. 1, 3 and 5%,...

We study the problem of detecting hierarchical ties in a social network by exploiting the interaction patterns between the actors (members) involved in the network. Motivated by earlier work using a rank-based approach, i.e., Rooted-PageRank, we introduce a novel timesensitive method, called T-RPR, that captures and exploits the dynamics and evolution of the interaction patterns in the network ...

Abstract. This study aims to investigate the application of artificial intelligence (AI) methods in predicting resilient modulus soil mixtures with polyethylene (PE) bottles and polypropylene (PP). The AI used are neural network (ANN) classification regression random forest (CRRF), modeling was conducted using a database 160 datasets. also evaluated importance different input parameters on accu...

the conceptualization of resilience as a general or multidimensional construct and recognizing the inhibitors and facilitators of it are the main issues in the resilience literature. therefore, the present study investigated the discriminant variables of educational resilient and emotional resilient groups in person-focused approach, to examine the general or multidimensional construct of resil...

Big cities in developing countries face many obstacles related to the built environment when confronted by socioeconomic inequalities, which is reflected uneven access basic living infrastructure, such as sanitation and housing. In light of new approaches traditional materials building techniques, this article aims investigate use digital fabrication tools production lightweight precast systems...
