As a laboratory demonstration platform, TUT-I mobile robot provides various experimentation modules to demonstrate the robotics technologies that are involved in remote control, computer programming, teach-and-playback operations. Typically, the teach-and-playback operation has been proved to be an effective solution especially in structured environments. The path generated in the teach mode an...

Application of multipath routing techniques in mobile ad hoc networks has been explored earlier, as multipath routing may help to reduce end-to-end delay, perform load balancing and consequently improve throughput. However, it has also been shown that the success of multipath routing in ad hoc wireless network depends on network topology and channel characteristics can severely limit the gain o...

The most common solutions to the light transport problem rely on either Monte Carlo (MC) integration or density estimation methods, such as uni& bi-directional path tracing or photon mapping. Recent gradient-domain extensions of MC approaches show great promise; here, gradients of the final image are estimated numerically (instead of the image intensities themselves) with coherent paths generat...

It is shown that the throughput capacity of wireless ad hoc networks using omni-directional antennas (OMN networks) is significantly decreased with the increased number of nodes. One major reason lies in the interference caused by using omni-directional antennas, which just broadcast radio signal in all directions. Thus, a communication with multiple short-ranged hops is suggested in such netwo...

Among the local consistency techniques used for solving constraint networks, path-consistency (PC) has received a great deal of attention. However, enforcing PC is computationally expensive and sometimes even unnecessary. Directional path-consistency (DPC) is a weaker notion of PC that considers a given variable ordering and can thus be enforced more efficiently than PC. This paper shows that D...

AGV systems are now becoming widely used in automatic material handling systems. One of the issues arising in applications is routing. This paper presents a bi-directional path layout and an algorithm for routing AGVs without conflicts. Mathematical relationships among certain key parameters of path and vehicle are derived to minimize the space requirements of the layout. The routing efficiency...
