A novel nonuniform cosine modulated filter bank is presented, mixing the concepts of warped DFT (Discrete Fourier Transform) filter bank and pseudoQMF system (Quadrature Mirror Filter). Unequal bandwidths are achieved by allpass transformation of uniform polyphase system. The cosine modulation results in real valued channel signals, and hence simplified subband processing. The considered filter...

evaluation of performance and productivity is among the fundamental concepts inmanagement. in order to achieve their goals, organizations must evaluate theirperformance. one of the important stages of performance appraisal is evaluation oforganization’s efficiency. banks, financial and credit institutions are among the mostimportant organizations of every economic system, because every activity...

Handwriting recognition has been one of the active and challenging research areas in the field of image processing and pattern recognition. It has numerous applications that includes, reading aid for blind, bank cheques and conversion of any hand written document into structural text form. Neural Network (NN) with its inherent learning ability offers promising solutions for handwritten characte...

This paper summarizes experiences and results of productively using knowledge discovery and data mining technology in a large retail bank. We present data mining as part of a greater effort to develop and deploy an integrated IT-infrastructure for loyalty based customer management, combining data warehousing, online analytical processing (OLAP), and campaign management together with data mining...

We introduce a framework for treating multirate filter banks for signal and image processing applications, as well as communication applications, in a unified way. We show how methods from group and ring theory can be applied to derive structural properties of filter banks.

Purpose. To determine whether the rate of graft detachment in patients undergoing the DSAEK procedure is influenced by the time elapsed between donor death and tissue implantation. Methods. Data on procedure outcome and donor tissue for patients undergoing the DSAEK procedure were reviewed. Data on time elapsed between harvest, processing, storage, and implantation of the tissue, as well as don...

This paper presents a decision support model aimed at the assessment of reputational risks associated with bank operation. The innovative aspect of the model is that it combines different types and sources of information: structured and unstructured, quantitative and qualitative, internal and external. Unstructured, qualitative and external aspects are represented by sentiment of news and blogs...
