While it is widely acknowledged that the performance improvement in current biometrics-based personal authentication systems is necessary, it is not clear what mechanisms could be used to improve the performance. In this paper, we formulate the problem of multiple biometrics integration and examine whether the improvement in performance could be achieved from integrating multiple biometrics. Fo...

In models with a capital spillover, the market outcome is not Pareto e cient since agents ignore the positive externalities caused by investment. One might conclude that taxes on investment or subsidies to consumption will reduce welfare. However in a model of endogenous growth, either a small tax on capital income, whose proceeds are wasted, increases growth and welfare or a small marginal sub...

This article is a call for action to the relevant stakeholders to improve access to care and treatment for patients with rare diseases in the Asia-Pacific region by looking into three main areas: (a) developing legislative definitions to confer enforceable protection, (b) creating or strengthening policies by objectively measuring the impact brought about by rare diseases and establishing platf...

Doubly-fed induction generator (DFIG) based wind turbines with traditional maximum power point tracking (MPPT) control provide no inertia response under system frequency events. Recently, the DFIG wind turbines have been equipped with virtual inertia controller (VIC) for supporting power system frequency stability. However, the conventional VICs with fixed gain have negative effects on inter-ar...
