In a wide-area network with high-speed links, congestion may lead to poor utilization and the degradation of the service provided to the users. This paper presents a Cooperative Congestion Management Scheme in which the intermediate nodes in the vicinity of a congested link share their resources to offload this link before packets are discarded. The scheme uses a progression of proactive contro...

The software industry has much to be proud of today. The worldwide software and services market generates over $221 billion and has become one of the most significant economic forces of our time. Technologically, the industry has pioneered extraordinary new developments that improve the productivity of companies every day: graphical user interfaces, relational databases, object-oriented program...

This study investigates the relation between walking speed and the distribution of peak plantar pressure and compares a traditional ten-region subsampling (10RS) technique with a new technique: pedobarographic statistical parametric mapping (pSPM). Adapted from cerebral fMRI methodology, pSPM is a digital image processing technique that registers foot pressure images such that homologous struct...

The number of users with Wi-Fi-enabled devices now competing for airtime continues to grow at an astonishing rate. Not only is the user base growing, so too is the number of devices, as more and more people whip out their dual mode smartphones for some tasks, while using a laptop or tablet for others. But that is not all. The average airtime demands from each user are also growing, as the mix o...

Per-ow queueing with sophisticated scheduling is a candidate architecture for networks that provide advanced Quality-of-Service (QoS) guarantees. The hardest and most interesting scheduling algorithms rely on a common computational primitive: priority queues. Large priority queues are built using calendar queue or heap data structures. To support such scheduling for a large number of ows at OC-...

ATM technology places strict performance requirements on ATM systems, especially considering the scalability of the SDH/SONET physical layer to high speeds. Throughput preservation of the link speed through protocols to a higher layer application is a known problem in high-speed communication systems. The problem is being addressed with design methodologies that offer high speed data paths, usi...

Multicast services, assisted by special hardware, are being considered as part of high-speed wide area networks in order to support new generations of multi-user applications. This paper describes an application multicast service for high-speed WANs which is capable of exploiting multicast hardware. Indeed, this research was conducted in context of the spanning tree hardware structure of IBM Ne...

variable rate application (vra) based on site specific crop management (sscm) is an effective approach for optimizing the application of agricultural inputs and preventing the undesirable environmental impacts. design, construction and evaluation of a map-based vra system was the main objective followed in this research. for variable rate application based on the generated map, a direct injecti...

This paper describes a pipeline analog-to-digital converter is implemented for high speed camera. In the pipeline ADC design, prime factor is designing operational amplifier with high gain so ADC have been high speed. The other advantage of pipeline is simple on concept, easy to implement in layout and have flexibility to increase speed. We made design and simulation using Mentor Graphics Softw...
