چکیده
In this paper we present a new Monte Carlo rendering algorithm that seamlessly integrates the ideas of shooting and gathering power to create photorealistic images. The algorithm can be explained as a generalisation of the well-known path tracing algorithm. Test results show that it performs signiicantly better for typical indoor scenes where indirect lighting is important.

Two optimal algorithms for finding bi-directional shortest path design problem in a block layout
In this paper, Shortest Path Design Problem (SPDP) in which the path is incident to all cells is considered. The bi-directional path is one of the known types of configuration of networks for Automated Guided Vehi-cles (AGV).To solve this problem, two algorithms are developed. For each algorithm an Integer Linear Pro-gramming (ILP) is determined. The objective functions of both algorithms are t...

متن کاملAn Extended Fault - Tolerant Link - State Routing Protocol in the Internet 1
Link-state routing protocols, such as OSPF and IS-IS, are widely used in the Internet today. In link-state routing protocols, global network topology information is first collected at each node. A shortest path tree (SPT) is then constructed by applying the Dijkstra’s shortest path algorithm at each node. Link-state protocols usually require the flooding of new information to the entire (sub)ne...
متن کاملEfficient path protection in bi-directional WDM systems
Bi-directional WDM transmission is a technique that allows data to be transmitted simultaneously in both directions of a fiber, with different sets of wavelength channels for each direction. Compared with unidirectional WDM systems, it not only saves the cost of deploying extra fibers, but also allows more flexible bandwidth provisioning. To exploit this flexibility, we investigate path protect...
متن کاملA Single-Fiber Bi-directional Self-Healing WDM Metro-Ring Network with Bi-directional OADM
We propose and demonstrate a single-fiber bi-directional WDM self-healing ring network with simple bidirectional OADM. By employing our proposed alternate-path switching scheme, the bi-directional traffic can be restored promptly under single fiber failure. Introduction Bi-directional wavelength division multiplexing (WDM) self-healing ring (SHR) network [1-2] is an attractive and cost-effectiv...
