In this paper, a new two-parameter window function - Raised semi-ellipse (RSE) is proposed. The obtained from fixed elliptical known as Semi-ellipse by raising the radius of minor axis parameter (β), and applied for design finite impulse response (FIR) digital filters. spectral parameters proposed are determined first compared with Kaiser – 2-parameter adjustable window. Subsequently, in its ap...

BACKGROUND Practices vary in the duration of newly initiated antidepressant treatment, even after adjusting for patient characteristics. It was hypothesised that this may be because of differences between practices in demographic (practice deprivation and antidepressant prescribing rates), organisational (practice size and proportion of female GPs), and clinical factors (proportion of new episo...

OBJECTIVE Evidence suggests that medication errors have a higher incidence in children and infants than in adults. At present, there is limited local data that investigates the drug prescription trends in pediatric populations. This study aims at understanding drug utilization patterns in pediatric patients at Sultan Qaboos University Hospital (SQUH), Oman. MATERIALS AND METHODS A retrospecti...

BACKGROUND Bacterial resistance due to antibiotic misuse is reported every day. Such threat calls for a consensus to develop new strategies to prevent the development of antibiotic resistance of bacteria. Medical doctors must play a pivotal role to control and prevent the misuse of antibiotics. There were complaints that prescribers are lacking behind in updates and advancement in the field. To...

This paper considers the problem of delay-dependent robust H∞ filtering for linear parameter-varying (LPV) systems with time-invariant delay in the states and outputs. It is assumed that the state-space matrices affinely depend on parameters that are measurable in real-time. By taking the relationship between the terms in the Leibniz-Newton formula and a suitable change of variables into accoun...

This article presents numerical analysis of mixed convection laminar flow of a second grade viscoelastic fluid due to cylinder of elliptic cross-section with prescribed surface heat flux. Dimensionless nonlinear analysis is computed employing Keller-box method. Skin friction coefficient and Nusselt number are emphasized specifically. These quantities are displayed graphically to examine their b...

The connection between the Bondi-Sachs (BS) and the Newman-Penrose (NP) framework for the study of the asymptotics of the gravitational field is done. In particular the coordinate transformation relationg the BS luminosity parameter and the NP affine parameter is obtained. Using this coordinate transformation it is possible to express BS quantities in terms of NP quantities, and to show that if...
