The emerging need for the current medical devices to achieve immediate visualization and performing diagnostic imaging at real time augurs the demand for high computational power of the associated electronic circuitry. The demand for such a high computational requirement is often met by using software methods to accelerate the computation which is possible only to a certain extent, impairing the feasibility of real time imaging and diagnosis. In this paper, a new method of using Digital Signal Processors (DSP) with a specialized Pipelined Vision Processor (PVP) embedded at the hardware level to accelerate the routinely time consuming imaging computation is proposed and validated. A lab prototype is built for the feasibility study and clinical validation of the proposed technique. This unique architecture of the PVP in a dual core Digital Signal Processor offers a high performance accelerated framework along with it’s large on chip memory resources and reduced bandwidth requirement provides as an ideal architecture for reliable medical computational needs. We have taken two sets sample studies from SPECT for validation – 27 cases of Thyroid Medical History and 20 cases of Glomerular Filtration Rate of Kidneys. The results were compared to definitive post scan SIEMENS image analysis software. From the statistical results, it is clearly shown that, this method achieved very superior accuracy and 250% acceleration of computational speed. OAPA

While the network traffic has seen exponential increase, the revenues have not maintained the same pace. New methods have to be explored to reduce this gap between traffic and revenue. One such method is convergence in networking layers. In this work, we study the convergence of OTN and DWDM layer from a network planning perspective. We compare the costs of planning networks without and with convergence and show that the multilayer planning offers least cost for higher traffic volumes.

In this paper we experiment and analyze the Multipath TCP (MPTCP) proposed by Internet Engineering Task Force (IETF). The authors consider MPTCP offerings such as multipath aggregation, increased throughput, enhanced resilience, network handover and employing various congestion control algorithms over multipaths to aggregate available bandwidth as key factors to assess experiments with various topologies.
