چکیده
This paper describes a new interface, which supports volume rendering with haptic interaction, between a haptic device and the application. The currently available GHOST SDK represents only the haptic environment as a hierarchical collection of geometric objects. We have developed a volume-based GHOST Application Programming Supplement Interface Library (APSIL) for volume visualization which is based on voxel representation, rather than on geometric representation. APSIL is an extension of the GHOST SDK and consists of some new classes to process volume haptic rendering and compute interaction forces according to the density of the volume data, velocity of movement, and environmental factors. Applications communicate with the haptic device through our APSIL library on a higher-level interface based on GHOST SDK.

Strategies to Overcome Network Congestion in Infrastructure Systems
Networked Infrastructure systems deliver services and/or products from point to point along the network. Demand for the services provided by such systems is typically cyclic, creating inefficiencies in capacity utilization. Congestion pricing provides incentives to shift demand from peak time periods to lower demand periods. This effectively increases the capacity of the system without the need...
