In this paper, we present a new structure for linear−phase filter banks without redundancy, which have unequal−length filters at each subband. First, we extend the simplified lattice structure of the linear−phase filter bank to the unequal−length linear−phase paraunitary filter bank. In general, the unequal−length linear−phase paraunitary filter bank has equal−length filters at both the analysi...

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 analyze the transmission effects of monetary policy in a general equilibrium model of the financial sector, with bank lending and securities markets. Bank lending is constrained by capital adequacy requirements, and asymmetric information adds a cost to outside bank equity capital. In our model, monetary policy does not affect bank lending through changes in bank liquidity; rather, it operat...

We study how corporate financing evolved during the Twentieth century in Britain. We document a remarkable transition from single to multiple firm-bank relationships. Larger, global, or transparent companies with greater needs for bank credit were more likely to add a bank, especially when located in more competitive local banking markets. Deregulation and intensifying competition in the bankin...

Several empirical studies have supported the hypothesis that bank relationships have economic value. By examining the effect of a Japanese bank failure on the profitability of client firms, this paper shows that the impact of a bank failure on clients depends on clients depends on the client’s characteristics and the method of bank liquidation, and that the value of bank relationships has been ...

The relationship between the target and acquiring banks in a bank merger is examined to determine if any factors contribute to the likelihood of a bank merger. Logistic models are used in an attempt to model the merger decision of both the target and the acquirer banks. I find some evidence larger banks holding riskier portfolios are more likely to acquire other banks. ** The author would like ...

Gravitational forces acting on in situ bank material act in concert with hydraulic forces at the bank toe to determine rates of bank erosion. The interaction of these forces control streambank mechanics. Hydraulic forces exerted by flowing water on in situ bank-toe material and failed cohesive material at the bank toe are often sufficient to entrain materials at relatively frequent flows and to...

To provide more insights into the responses of the soil seed bank and vegetation to human disturbance intensity, we selected four land use types, including: native grassland (no human disturbance), abandoned artificial grassland (light human disturbance), artificial grassland (moderate human disturbance), and farmland (severe human disturbance) in a semi-arid climate of northern China. The spec...

Increasing attention in invasion biology is being paid to measuring and understanding the impacts of invasive species. For plant invasions, however, the impact of invasion on soil seed bank communities has been under-studied. At six sites in southern Germany, we investigated whether areas invaded by Solidago gigantea and Solidago canadensis experienced a reduction in seed bank species richness,...

A growing number of commentators advocate enhancing the role of market discipline in the banking industry. They argue that if private sector stakeholders can discourage excessive risk-taking and encourage safe banking practices through the pricing of bank securities, then the extensive regulatory framework currently in place may be unnecessarily burdensome. In the wake of recent studies conclud...
