Biometrics consists of techniques for uniquely recognizing humans based upon one or more intrinsic physical or behavioral traits such as Iris, fingerprint, Face and Palm geometry etc. To overcome the limitations of Unimodal biometric system, a multimodal biometric is proposed. Amongst the various fusion levels, feature level fusion is expected to offer better recognition. Feature level fusion f...

This paper introduces the system of Word Segmentation and analyzes its evaluation results in the Fourth SIGHAN Bakeoff . A novel method has been used in the system, which main idea is: firstly, the main problems of WS have been classified, and then a cascaded model has been used to gradually optimize the system. The core of this WS system is the segmentation of ambiguous words and the internal ...

This paper describes a multilevel Z-source inverter for solar photovoltaic applications. The conventional power conversion topology performs either buck or boost the input voltage for non linear load depending upon duty ratio and modulation index in a multiple stage conversion with the help of impedance source passive network (L and C), which is usually known as Z-Source, which couples the n le...

The idea of learning cascade, recently introduced to characterize the progressive evolution of the immune system response from low-aanity to high-aanity lymphocites, is explored by means of extensive computer simulations. In a recent work 7] it was proposed that the Immune System (IS) learns how to withstand attacks by foreign invaders, the \Antigens" (Ag for short) by means of a so-called \lea...

In this study, artificial neural networks (ANNs) have been used for performance analysis of a CO2/NH3 cascade refrigeration system using a data set, obtained from a thermodynamic model implemented in EES. Thermodynamic parameters of the system are estimated in terms of condensing temperature of ammonia, evaporating temperature of carbon dioxide, condensing temperature of carbon dioxide and temp...

Cray began delivery of their next generation XC30 supercomputer systems in late 2012. One of the first systems, “Edison,” was delivered to NERSC and in this paper we present preliminary performance results obtained on this machine. The primary new feature of the XC30 architecture is the Cray “Aries” interconnect that includes a 48-port high radix router with a dragonfly topology. To demonstrate...

A comprehensive understanding of how resources are utilized is required to support a circular bioeconomy. This article presents the first systematic assessment forest biomass flows and stocks in Portugal analyzes circularity resource efficiency through set indicators, while providing recommendations for their use improvement different contexts. Material Flow Analysis was developed 2015, includi...

A cascade CRISPR/cas nucleic acid diagnostic system, which can achieve high-sensitive and single-base specificity without target amplification, was developed for miRNA detection.

Venous ischemia in a closed compartment results congestion, impeded blood supply, cell death and cascade of events that involves immune system to remove cellular debris.

Although conventionally associated with fibrin clot degradation, recent work has uncovered new functions for the tissue plasminogen activator (tPA)/plasminogen cascade in central nervous system physiology and pathology. This extracellular proteolytic cascade has been shown to have roles in learning and memory, stress, neuronal degeneration, addiction and Alzheimer's disease. The current review ...
