Dual wavelet frames and their associated dual framelet filter banks are often constructed using the oblique extension principle. In comparison with the construction of tight wavelet frames and tight framelet filter banks, it is indeed quite easy to obtain some particular examples of dual framelet filter banks with or without symmetry from any given pair of low-pass filters. However, such constr...

Providing blood units for patients with an antibody to a high-prevalence antigen or with multiple common antibodies is a constant challenge to the blood banks. Finding a compatible donor requires extensive screening, with incurs a large amount of investment. In this article, we share our experience of organizing a rare donor inventory with limited resources, we include the strategy used for fin...

This study determines whether it is possible to distinguish between conventional and Islamic banks in the Gulf Cooperation Council (GCC) region on the basis of financial characteristics alone. Islamic banks operate under different principles, such as risk sharing and the prohibition of interest, yet both types of banks face similar competitive conditions. The combination of effects makes it unc...

This paper develops a theory of trust in lending, and uses it to analyze the potential market segmentation between banks and fintech lenders. Trust enables lenders to have assured access to financing regardless of market conditions, whereas a loss of trust makes this access conditional on market conditions and the perceived incentives of self-interested lenders to make prudent loans. As long as...

This study seeks to determine the impact of mergers on efficiency and productivity of commercial banks in Malaysia for the period from 1995 until 2005. The study uses a non-parametric approach, namely DEA, to estimate the efficiency scores and to construct the Malmquist productivity index. To enable this estimation, three bank inputs and outputs were used. Amongst the findings are that banks ex...

Perfect reconstruction (PR) filter banks have found numerous applications, and have received much attention in the literature. For linear filter banks, necessary and sufficient conditions for PR have been established for most practical situations. Recently, nonlinear filter banks have been proposed for image coding applications. These filters are generally simple, and produce better results tha...

Privatization which refers to the transition of ownership and management of state-owned enterprises to the private sector, is one of the main drivers of economic prosperity. In this paper, the performance of the state, private, and privatized banks have been compared through examining the effects of privatization in the banking system on its performance. The data from 11 banks during the 13-yea...

The time to fix the roof is when the sun is shining risk management has not been uppermost on the Islamic banking sector’s agenda in recent years. It is crucial for Islamic banks (IBs) to have comprehensive risk management framework as there is growing realization among IBs that sustainable growth critically depends on the development of a comprehensive risk management framework. Islamic b...

An accurate semi-analytical approach for modeling electromagnetic scattering and guidance by photonic crystals formed by layered parallel-arrays or crossed-arrays of circular cylinders is presented , using the lattice sums technique, the T matrix algorithm, and the generalized reflection and transmission matrices for a layered system. The method is quite general and applies to various configura...
