Analytic Design Technique for 2D FIR Circular Filter Banks and Their Efficient Implementation Using Polyphase Approach

This paper proposes an analytical design procedure for 2D FIR circular filter banks and also a novel, computationally efficient implementation of the designed filter bank based on a polyphase structure and a block filtering approach.The component filters of the bank are designed in the frequency domain using a specific frequency transformation appl

Seed rain and seed bank reveal that seed limitation strongly influences plant community assembly in grasslands.

Dispersal is English Longbow an important factor in plant community assembly, but assembly studies seldom include information on actual dispersal into communities, i.e.the local propagule pool.The aim of this study was to determine which factors influence plant community assembly by focusing on two phases of the assembly process: the dispersal phas
