DART is an ATM Network Interface Controller chip designed for both high bandwidth and low overhead communication. Innovative features are direct, protected application access to/from the network, host-assisted flow control, and¨message processing¨for flexible low overhead communication mechanisms. DART is being manufactured as a commercial product by(More)
It is well-known that the FDDI guarantees a bounded access delay and an average bandwidth for synchronous traac. However, this fact alone cannot eeectively support many real-time applications that require the timely delivery of each critical message. We solve this problem by developing a synchronous bandwidth allocation SBA scheme which calculates the(More)
The asynchronous transfer mode ATM is expected to be the multiplexing and switching technique for future broadband integrated service digital networks BISDNs which can transport almost all types of traac including bursty data traac and continuous voiceevideo frames. However, this capability cannot be realized without a proper congestion-control scheme. This(More)
In order to realize real-time communication over Ether-net or fast Ethernet, one must be able to bound the medium access time within an acceptable limit. The multiple access nature of an Ethernet makes it impossible to guarantee a deterministic medium access time (hence packet delivery deadlines) to individual stations. However, one can bound the medium(More)

MapReduce has been used at Google, Yahoo, FaceBook etc., even for their production jobs. However, according to a recent study, a single failure on a Hadoop job could cause a 50% increase in completion time. Amazon Elastic MapReduce has been provided to help users perform data-intensive tasks for their applications. These applications may have high fault(More)
Primary sensory neurons in the DRG play an essential role in initiating pain by detecting painful stimuli in the periphery. Tissue injury can sensitize DRG neurons, causing heightened pain sensitivity, often leading to chronic pain. Despite the functional importance, how DRG neurons function at a population level is unclear due to the lack of suitable(More)
Time-stamp in image shows the time when an image was taken, and which is important information for retrieval. An automatic photo time-stamp recognition approach is proposed in this paper. The proposed method consists of three steps: 1) A photo is roughly segmented to determine which area contains the photo time-stamp. Four detecting areas are chosen in this(More)
