We treat the problem of scheduling a owshop with pallet requirements. Each job in the owshop needs a pallet the entire time, from the start of its rst operation until the completion of the last operation, and the number of pallets in the shop at any given time is limited by an integer K. We prove that the problem is NP-hard in the strong sense for m 2 and K 3, and for m 3 and K 2, where m is th...

Although pallets have traditionally been constructed from wood, there has a shift towards making them plastic and other composite materials. Subsequently, the storage transportation industry inundated with questions about ‘the best’ pallet material type in relation to supply chain. In addition, rapidly changing global manufacturing environment, players difficulty justifying high capital cost of...

ÐThis paper considers the problem of illuminant estimation: how, given an image of a scene, recorded under an unknown light, we can recover an estimate of that light. Obtaining such an estimate is a central part of solving the color constancy problemÐthat is of recovering an illuminant independent representation of the reflectances in a scene. Thus, the work presented here will have application...

Smart structures are highly interconnected adaptive systems that are coordinated by cyber systems to optimize specific system objectives. To capture realistic IoT scenarios we must employ threat models that allow untrusted behavior and address system vulnerabilities, exploits and attack vectors. Resilience is defined in terms of stability, resistance to damage and self-healing. In this paper we...
