This paper considers the relationship between economic factors and national security. While considering a broad number of issue areas, the principal theme of the course is the way in which economic factors (as immigration) fundamentally influence the national security of the region, and the way in which those factors shape and constrain the strategies chosen to pursue that security. South-South...

All previously proposed position based routing algorithms for wireless ad hoc networks were based on forwarding the actual message along multiple paths toward an area where destination is hopefully located. The significant communication overhead can be avoided if the routing strategy is changed. We propose that the source node issues several search 'tickets' (each ticket is a 'short' message co...

We consider the problem of estimating the endpoints (source and destination) of a transmission in a network based on partial measurement of the transmission path. Sensors placed at various points within the network provide the basis for endpoint estimation by indicating that a specific transmission has been intercepted at their assigned locations. During a training phase, test transmissions are...

In this paper, we study Resource Constrained Best Upgrade Plan (BUP) computation in road network databases. Consider a transportation network (weighted graph) G where a subset of the edges are upgradable, i.e., for each such edge there is a cost, which if spent, the weight of the edge can be reduced to a specific new value. In the single-pair version of BUP, the input includes a source and a de...

Determination of source-destination connectivity in networks has long been a fundamental problem, where most existing works are based on deterministic graphs that overlook the inherent uncertainty in network links. To overcome such limitation, this paper models the network as an uncertain graph where each edge e exists independently with some probability p(e). The problem examined is that of de...

The movement of health care workers from countries with resource scarcity and immense need ("source" countries) to areas of resource abundance and greater personal opportunity ("destination" countries) presents a complex set of decisions and relationships that affect the development of international health care systems. We explore the extent to which ethical quandaries arising from this movemen...

Zika virus is an Arbovirus identified first time in 1947 in Uganda. Zika epidemic is a threat far greater than the Ebola outbreak. The World Health Organization has urged Asian countries to be vigilant about the risk of spreading Zika virus and preventive measures to control it. In Iran, 64 species of mosquitoes from Culicidea family have been reported three of which belong to the Aedes genus, ...
