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

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 …

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 …

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

We introduce cube-connected circulants as efficient models for communication networks.
We give an algorithm for computing a shortest path between any pair of vertices in a cube-…

Proper design of stent for application at specific aneurysm effect arteries could help to reduce
the issues with thrombosis and aneurysm. In this paper, four types of stent configuration …

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) …
