This paper presents a game theoretic model that analyzes resource allocation strategies against an adaptive adversary to secure cargo container transportation. The defender allocates security resources that could interdict an unauthorized weapon insertion inside a container. The attacker observes the defender’s security strategy and chooses a site to insert the weapon. The attacker’s goal is to...

This paper presents a Heuristic Genetic Algorithm (HGA) for optimizing three dimensional (3D) arbitrary sized heterogeneous boxes into a container, by considering practical constraints facing in the shipment container loading industries. Objective of this research is to pack heterogeneous boxes of varying length, width and height into a container of standard dimension, without violating major p...

Container terminals play an important role in global cargo transportation and they have become an essential intermodal interface between the sea and the land. In the container terminal, the service area is often arranged into rectangular blocks, which leads to a mesh-like path topology. We present a mathematical model for general container routing in mesh yard layouts. Based on this model, a si...

In recent years, three types of linacs have been developed for large container inspection for customs application, viz., S-Band 9MeV travelling-wave (TW) linacs, S-Band 6MeV Standing-wave (SW) linacs and XBand 2.5MeV (SW) linacs. In cooperation with Tsinghua Tongfang Co. Ltd, a series of container inspection systems has been produced. Seven sets of large container inspection systems with 9MeV T...

Common middleware platforms support software components by providing a number of standard container services. Adding new container services can adapt a system to changed requirements without modifying its constituent components. Custom-made container services can intercept communication calls between system’s components and enforce new or changed requirements. Hence, legacy or off-the-shelf com...

In this contribution we optimize the transportation of containers in the hinterland of a local area with one terminal and one depot for empty containers and trucks. There are several customers who want to receive goods by inbound containers and several customers who want to ship goods by outbound containers. Additionally, there are empty inbound containers and empty outbound containers. We pres...

We have developed a new technique based on the passive gamma method for measuring a quantity of uranium in a uranium waste container (1200 liter volume). The measurement system consists of three NaI (Tl)detectors, one High Purity Germanium (HPGe) detector and a handling system. The measuring method uses two discrete gamma-ray energies emitted from the daughter nuclide Pa-234m (1001 keV and 766 ...

Sanitation improvement is crucial in saving lives that are lost due to water contamination. Progress towards achieving full sanitation coverage is still slow in low-income informal settlements in most developing countries. Furthermore, resources are being wasted on installing facilities that are later misused or never used because they do not meet the local demand. Understanding demand for impr...

This paper formulates the 3D Container ship Loading Planning Problem (3D CLPP) and also proposes a new and compact representation to efficiently solve it. Containers on board a Container ship are placed in vertical stacks, located in different sections. The only way to access the containers is through the top of the stack. In order to unload a container at a given port j, it is necessary to rem...
