Stroke is one of the three most common causes of death and the sixth most common cause of disability worldwide. Building effective and efficient stroke care systems is critical for improving patient outcomes in the prevention, treatment, and rehabilitation of stroke. A systems approach is necessary to improve the way stroke is treated so that patients have access to the most appropriate treatment...
In this paper, we study a cooperative spectrum sensing scheme for cognitive radio systems where each sensor transmits multibit quantized information to a fusion center where the decision about the availability or occupancy of the channel is made. In particular, we introduce a linear-quantization scheme that is based on a single parameter and derive the optimal detector at the fusion center...
In this paper, we present the error probability expressions for a wideband coherent spatially correlated Multiple Input Multiple Output (MIMO) channel in low signal to noise ratio (SNR) regimes. Prior works have depicted a decrease in performance due to spatial correlation in high SNR regimes. This work proves that in a power limited broadband MIMO system, spatial correlation across the channel fading...
In this paper, we propose a low complexity multi-bit multi-user combining strategy for cooperative spectrum sensing in cognitive radio networks. We consider the optimal detector where the fusion center receives multi-bit sensing information from several nodes and combine them to make a final decision on the status of the channel. Each node employs a linear quantization technique to generate its multi-bit...
It is crucial than ever to measure manufacturing losses due to non-compliance of customer specifications. To assess these losses, industry is widely using proportion of non conformance PNC for performance evaluation of their manufacturing processes. Various methods have been proposed to estimate PNC for univariate quality characteristics, however estimating an accurate PNC for non-normal multivariate...
