A new design method for complex-valued two-channel FIR filter banks with both orthogonality and symmetry properties is developed. Based on a novel linear matrix inequality (LMI) characterization of trigonometric curves, ...

Volatilities and correlations for equity markets rise more after negative returns shocks than after positive shocks. Allowing for these asymmetries in covariance forecasts decreases mean-variance portfolio risk and ...

The symmetry of an optical waveguide determines its modal degeneracies. A fiber with rotational symmetry of order higher than 2 has modes that either are nondegenerate and support the complete fiber symmetry or are twofold ...

Background and Objective Many women do not recognize their risk for coronary heart disease, or identify and respond to cardiac symptoms by seeking medical assistance when symptoms occur. These factors contribute to delays ...

The synchromesh type synchroniser has been introduced to dual clutch transmission applications for gear selection prior to shifting. Historical research into this type of mechanism has targeted the application to manual ...

Many interesting issues are posed by synchronization of cycles. In this paper, we define synchronization and show how the degree of synchronization can be measured. We propose heteroscedasticity and serial correlation ...

This paper addresses the causes of synchronous torques in split-phase induction motors. First, an analytical model is outlined to describe the processes involved in producing synchronous torques. This involves the consideration ...

This research investigates the synergies of applying a Rapid Application Development (RAD) process model to support e-Business project management. The paper reports on the results of eleven unstructured interviews with ...

The pressures on existing infrastructures are significant: demand is beginning to outstrip supply; aging infrastructure poorly maintained presents an increasing risk; and rejection of urban sprawl forces increasing population ...
