A new filter bank approach for speaker recognition front-end is proposed. The conventional mel-scaled filter bank is replaced with a speaker-discriminative filter bank. Filter bank is selected from a library in adaptive basis, based on the broad phoneme class of the input frame. Each phoneme class is associated with its own filter bank. Each filter bank is designed in a way that emphasizes disc...

We study the genealogical structure of samples from a population for which any given generation is made up of direct descendents from several previous generations. These occur in nature when there are seed banks or egg banks allowing an individual to leave offspring several generations in the future. We show how this temporal structure in the reproduction mechanism causes a decrease in the coal...

River banks are exposed to bank erosion and destruction. One of the river engineering goals is to provide human life requirements and reduce river danger. So spreading extent of this phenomenon, whose risk and other important factors must be recognized. Using groins is one of the control ways that by accurate design and accurate performance, bank erosion control and field reclamation would be p...

How to design bank capital requirements when banks can misreport the value of their assets? We show that the answer depends critically on the existence of secondary markets for bank assets. Without secondary markets, capital requirements based on banks’reporting are more socially desirable than a fixed capital requirement if savings on costly bank capital are suffi ciently high. Yet with second...

In recent work (Gopinath and Stein 2017), we explore how a currency like the dollar can become entrenched as a dominant global currency, focusing on the two-way feedback between trade invoicing and banking structure. The basic idea is that when a larger share of a country’s imports are invoiced in dollars, its citizens have a greater demand for dollar-denominated safe claims. This in turn leads...

This article examines whether the dividendpolicy of bank holding companies is used as a signal of their quality. The study found evidence to support the dividend signaling argument-that is, that there is a positive relationship between bank dividendsper share and bank quality rating. Aaiiitionally, an inverse relationship between the dividend payout ratio and bank quality was found. Therefore, ...

T his study investigates the impact of bank regulation on financial development in the MENA countries for the period 1995-2014. Restrictions on activity, foreign banks, and capital were used as proxies for bank regulation. Also, bank supervisory power, independence, private monitoring, and moral hazard were used as proxies for bank supervision. Liquid liabilities, private credit, and...

A flotation bank is a serial arrangement of cells. How to optimally operate a bank remains a challenge. This article reviews three reported strategies: air profiling, mass-pull (froth velocity) profiling and Peak Air Recovery (PAR) profiling. These are all ways of manipulating the recovery profile down a bank, which may be the property being exploited. Mathematical analysis has shown that a fla...
