Hubs are facilities to collect arrange and distribute commodities in telecommunication networks, cargo delivery systems, etc. In this paper, an uncapacitated phub center problem in case of single allocation and also multiple allocation will be introduced in which travel times or transportation costs are considered as fuzzy parameters. Then, by proposing new methods, the presented problem is con...

Most work in the deep learning systems community has focused on faster inference, but arriving at a trained model requires lengthy experiments. Accelerating training lets developers iterate faster and come up with better models. DNN training is often seen as a compute-bound problem, best done in a single large compute node with many GPUs. As DNNs get bigger, training requires going distributed....

This study was inspired in part by calls for research to explore the ubiquitous phenomenon of phubbing in the academic environment. The goal of our study is to explore the phenomenon of phubbing and its consequences among students. Combining observations, questionnaires, quasi-experimental research design and focus groups interviews, our findings suggest that students phub a substantial amount ...

New formulation and a branch-and-cut algorithm for the multiple allocation p-hub median problem Sergio García, Mercedes Landete and Alfredo Marín Septiembre 2011 ISSN 1576-7264 Depósito legal A-646-2000 Abstract This article deals with the uncapacitated multiple allocation phub median problem, where p facilities (hubs) must be located among n available sites in order to minimize the transportat...

Lately, increasing concern has focused on the incessant and intrusive use of smartphones across a wide range interpersonal relational contexts. Of is that many people appear to snub someone during face-to-face interactions by focusing more their smartphone than partner, namely, phubbing. Individuals with insecure attachment styles may phub intimate others often. However, such relationships have...
