The unpredictability of the occurrence of epileptic seizures contributes to the burden of the disease to a major degree. An automatic system that detects seizure onsets would allow patients or the people near them to take appropriate precautions, and could provide more insight into these phenomena, thereby revealing important clinical information. Thus,(More)
For many decades correlation and power spectrum have been primary tools for digital signal processing applications in the biomedical area. The information contained in the power spectrum is essentially that of the autocorrelation sequence; which is sufficient for complete statistical descriptions of Gaussian signals of known means. However, there are(More)
Epilepsy is characterized by the spontaneous and unforeseeable occurrence of seizures, during which the perception or behavior of patients is disturbed. An automatic system that detects seizure onsets would allow patients or the people near them to take appropriate precautions, and could provide more insight into these phenomena. The use of non-linear(More)

The third generation mobile system or Universal Mobile Telecommunication System (UMTS) offers IP based multimedia applications and services with end-to-end quality of service (QoS) guarantee. The key part providing these services is the policy-based QoS control architecture in the IP Multimedia Subsystem (IMS). In this tutorial article, we describe the(More)
Epilepsy is a pathological condition characterized by the spontaneous and unforeseeable occurrence of seizures, during which the perception or behaviour of patients is disturbed. An automatic early detection of the seizure onsets would help the patients and observers to take appropriate precautions. Various methods have been proposed to predict the onset of(More)
For power-constrained wireless ad hoc networks, a crucial issue in routing and multicasting is to conserve as much power as possible while still achieving good throughput performance. In this paper, we propose a class of power-efficient multicasting algorithms using a new cost function that jointly optimizes power conservation and path efficiency.(More)
– An analytical formulation of the outage probability in terms of bit error rate specification for variable bit rate (VBR) multiclass services in the uplink of a multirate DS-CDMA-based cellular system is presented. The analytical framework is formulated for the general case in which different traffic classes have different spreading gains and within a(More)
