Communication bandwidth

With suitable scan-line delay circuits, the filter may be applied in real time to live video images. In data communications, bandwidth extrapolation offers the opportunity to make far better use of channel capacity than is now possible. The bounded methods produce their most impressive restorations when o(x) spends a lot of time at or near the bounds. The present method was designed for use with both upper and lower bounds, which makes it ideal for the bilevel signals used in digital transmission. 

INCREASING NEEDS AND SOLUTIONS FOR COMMUNICATION BANDWIDTH AND PROCESSING...

The performance of a system is largely dependent on balancing transactional demand with processing power and communication bandwidth. One is therefore required to think about the specification of both in assessing likely performance. Note that most systems consist of large numbers of components and not all will be equally performant. The system as a whole will be compromised by the slowest dependency and determining which element that will be can be complex. 

The dual port design guarantees a very high communication bandwidth and, therefore, avoids a traffic bottleneck for the data exchange between master and slave. The number N of slaves to be controlled and served by the master processor is variable and can be installed by the operating system. It is limited only by the electrical characteristics of the master bus. 

Besides timing constraints there are other resource constraints such as limited memory (RAM and ROM), power consumption, communication bandwidth, and hardware costs (Graaf et al., 2003). The in-depth analysis of resource limitations if often dispensed with by over-dimensioning hardware (Hanninen et al., 2006). Possibly, this is the case because general software development technologies do not offer features to effectively deal with these constraints (Graaf et al., 2003). 

Examples such as the preceding demonstrate that the remarkable IT advances we have seen—in speed, data storage, and communication bandwidth—have been facilitated in no small way by contributions from the chemical sciences. A recent article by Theis and Horn, of IBM, discusses basic research in the information technology industry and describes the ongoing—indeed growing—importance of nanoscale chemisffy in the IT community. ... 

The SSR machine and software components engaged in communication will need adequate net working/communication protocols with appropriate characteristics for carrying the needed communication bandwidth, handling errors and retransmissions, reliable routing, and end point addressing. 

Making interaction more natural is one of the promises of multimodal interfaces. Research on evaluating multimodal interfaces dates back to the mid 1980s [5] and since then it is seen as a promising approach to improve desktop interaction techniques. Multimodal interaction techniques are considered as a potential way to increase communication bandwidth between users and systems and to enhance users satisfaction and comfort by providing a more natural way of interacting with computer systems [5], [6]. 

The deployment of multiple mobile robots for USAR using this organizational structure for the robot collective is the proposed solution in this research. As described earlier, the design for autonomous coordination using the hierarchical structure for the robot collective has been derived from the desire to make efficient use of robot onboard computational power and communication bandwidth while attempting to alleviate human supervisor cognitive workload levels and loss in situation awareness. The schematic ofthe SHMRS equipped with a hierarchically structured robot collective is illustrated in Figure 1. 

Such a method is in contrast to the dedication of a single robot to perform the bulk of the computation and communication within a hierarchically structured collective. In a horizontally structured collective, robots are all capable of executing the waypoints allocation algorithm by themselves. This reduces the likelihood of a total loss in the capability for autonomous coordination when a particular robot fails in the field. Yet, this also implies that each robot requires information such as the map of the mission environment as well as the position and visited or skipped way-points from each member of the collective. Furthermore, as Figure 4 indicates, this means that each robot must establish communication links with all other robots within the collective. Due to these reasons, all robots in ahorizontally stmctured collective must have sufficient computational power and communication bandwidth to provide, procure, and process the necessary information for coordination.
