We present a multi-core, GPU-based framework for simulation and visualization of two-dimensional floods, based on the full implementation of Saint Venant equations. A validated CPU-based flood model was converted to NVIDIA’s CUDA architecture. The model was run on two different NVIDIA graphics cards, a GeForce 8400 GS and a Tesla T10. The model was tested using two case study applications. Impl...

Payment card associations offer both debit and credit cards and, until recently, engaged in a tie-in on the merchant side through the so-called honor-all-cards (HAC) rule. The HAC rule came under attack on the grounds that the credit and debit card markets are separate markets and that the associations lever their market power in the “credit card market” to exclude on-line debit cards and there...

Consider three players Alice, Bob and Cath who hold a, b and c cards, respectively, from a deck of d = a+ b+ c cards. The cards are all different and players only know their own cards. Suppose Alice and Bob wish to communicate their cards to each other without Cath learning whether Alice or Bob holds a specific card. Considering the cards as consecutive natural numbers 0, 1, ..., we investigate...

In this article, we present the rationale, development and preliminary evaluation of a novel set materials to encourage improve consideration users their needs during process architectural design. Our focus is specifically on two areas: user-centred design principles spatial cognition research. To end, developed decks flash-cards, termed Architectural Strategies Cards (72 cards) Spatial Cogniti...

Network smart cards are smart cards with networking capabilities. They have opened new opportunities for the use of smart cards in Internet applications. At the same time, network smart cards are exposed to network security threats just as other computers on the Internet. Unfortunately, existing designs of network security mechanisms, such as packet filtering, may not be best suited for smart c...

Smart cards (also called chip cards or IC-cards) are portable modest computing devices with programmable data store and certain tamper-resistance capabilities. They are embedded in a plastic card that looks like a traditional magnetic stripe credit-card. We review the state of the art of e-commerce applications of smart cards.

Till recently it was impossible to have more than one single application running on a smart card. Multiapplication cards, and especially Java Cards, now make it possible to have several applications sharing the same physical piece of plastic. Today, these cards accept to load code only after an authentication. But in the future, the cards will be open an everybody should be authorized to upload...
