We consider three different versions of the Zak transform (ZT) for discrete-time signals, namely, the discretetime ZT, the polyphase transform, and a cyclic discrete ZT. In particular, we show that the extension of the discrete-time ZT to the complex z-plane results in the polyphase transform, an important and well-known concept in multirate signal processing and filter bank theory. We discuss ...

Umbilical cord blood transplants are now used to treat numerous types of immune- and blood-related disorders and genetic diseases. Cord blood (CB) banks play an important role in these transplants by processing and storing CB units. In addition to their therapeutic potential, these banks raise ethical and regulatory questions, especially in emerging markets in the Arab world. In this article, t...

Traditional monetary theory has largely ignored the role of bank equity. Bank-centred accounts of how monetary policy affects the real economy usually focus on the role of reserves and reserve requirements in determining the volume of demand deposits and, in the case of the bank lending channel, bank loans. As Benjamin Friedman (1991) observed, “Traditionally, most economists have regarded the ...

The customer group of small and medium enterprises (SME) was only rarely an object of investigation. Especially SMEs are a difficult group for banks to be profitable in. An obvious trend in this context is the strategy of banks to increase profits by improving cross-selling fi...

The purpose of this paper is twofold. First, a comprehensive review is performed on the existing two-channel FIR filter banks as well as on the design techniques proposed in the literature for designing these banks. We concentrate on alias-free banks. These banks can be first classified into perfect-reconstruction and nearly perfect-reconstruction banks. The nearly perfectreconstruction filter ...

Online banking applications are used by more and more people all over the world. Most of the banks are providing these services to their customers. The authentication methods varies from the basic user and password to username and a onetime password (OTP) generated by a virtual or a physical digipass. The common thing among authentication methods is that the login wepage is provided through a s...

Despite progress in the development of computational means, human input is still critical in the production of consistent and useable aligned corpora and term banks. This is especially true for specialized corpora and term banks whose end-users are often professionals with very stringent requirements for accuracy, consistency and coverage. In the compilation of a high quality Chinese-English le...
