In order to detect the obstructive sleep apnea (OSA) accurately, a non-contact way using Doppler radar is presented in this paper. The residual comparison based algorithm has been proposed to enhance the body movement cancellation and pre-event baseline calculation, so that the OSA event can be detected accurately. The experimental result shows the effectiveness of the proposed method for diagnosing...
Large-scale self-organised systems, such as distributed community energy systems, have called for coordination approaches that are able to deal with issues such as heterogeneity, inter-dependence and dynamic variability. Holonic institutions have been proposed as an approach to converging the structuration required for multi-scale, multi-criteria optimisation in nested enterprises with the formal...
Consumer acceptance is of great interest in the adoption of novel multimedia products and services. A number of factors can greatly influence the customer experience during a video session, impacting the acceptability of the product or service. Factors such as the Technical Quality (TQ) which covers the technical aspects of the signal quality can be controlled from the network provider. On the other...
A new intra coding method based on one dimensional line prediction with one dimensional transform is presented. The H.264/AVC design includes a multidirectional spatial prediction method to reduce spatial redundancy by using neighboring samples as a prediction for all the samples in a block of data to be encoded. In the proposed intra coding method, the spatial prediction is performed based on line...
Inter-organizational collaboration often occurs in complex, dynamic and unpredictable environments. Regulating structures should be represented explicitly and independently from the acting components at different levels of abstraction in order for stakeholders to be able to analyze the overall setup and decide on their participation. This paper proposes a framework for describing collaboration relationships...
Most of previous works on coverage problem are based on omni-directional sensing model. Due to different sensing capability in different direction, directional sensor networks require new solutions. We present two direction optimizing algorithms: greedy direction adjusting (GDA) algorithm and equitable direction optimizing (EDO) algorithm. GDA algorithm optimizes direction merely according to the...
