Background Endotracheal suctioning (ETS) is one of the most common invasive procedures
performed by critical care nurses (CCNs) to remove accumulated pulmonary secretions, …

In this paper, we extend traditional hub location models for an intermodal network design on
a sparse network structure. While traditional hub location problems have been employed for …

Water resource allocation is the process of assessing and determining a mechanism on
how water should be distributed among different regions, sectors and users. Over the recent …

We propose a generalized model of drayage operations that incorporates the coupling and
precedence principles, allows for live and separation operation modes, relaxes the …

We study the uncapacitated 2-allocation p-hub median problem (U2ApHMP), which is a
special case of the well-studied hub median problem. The hub median problem designs a hub …

Interconnection networks provide an effective mechanism for exchanging data between
processors in a parallel computing system. One of the most efficient interconnection networks is …

Cayley graphs are highly attractive structures for communication networks because of their
many desirable properties, including vertex-transitivity and efficient routing algorithms [4]. The …

The convoy movement problem (CMP) involves the routing and scheduling of a large
number of vehicles and personnel across a network. A convoy is a group of (typically, army) …

We study recursive cubes of rings as models for interconnection networks. We first redefine
each of them as a Cayley graph on the semidirect product of an elementary abelian group by …

This research aims to provide a comprehensive analysis of halal certification processes,
consumer perceptions, and the regulatory landscape in Batam City, Indonesia. The study …
