: We present a new input device for controlling three-dimensional graphics applications: the YoYo. The device consists of three elastically connected rings in a row, which can be m...
Abstract. Electronic payment systems for wireless devices need to take into account the limited computational and storage ability of such devices. Micropayment schemes seem well su...
The VPN Tree Routing Conjecture states that there always exists an optimal solution to the symmetric Virtual Private Network Design (sVPND) problem where the paths between all ter...
