—The lifting scheme has become an important tool for designing filter banks and transforms of digital signal processing. Recently, the conventional lifting scheme that concerns the construction of 2-channel filter banks has been extended to M-channel filter banks (M > 2) bringing up the desirable properties of the lifting scheme to a broader range of(More)
In this paper we present an efficient VLSI architecture focusing on M-channel multirate filter banks using the lifting scheme. Since the M-channel lifting factorization results in a signal flow graph with an irregular structure, the architecture must have a high degree of flexibility to allow the implementation of basically different lifting(More)
BACKGROUND Aspergillus niger prolyl endoprotease (AN-PEP) efficiently degrades gluten molecules into non-immunogenic peptides in vitro. AIM To assess the efficacy of AN-PEP on gluten degradation in a low and high calorie meal in healthy subjects. METHODS In this randomised, double-blind, placebo-controlled, cross-over study 12 healthy volunteers(More)
UNLABELLED The use of paracetamol as tool to determine gastric emptying was evaluated in a cross over study. Twelve healthy volunteers were included and each of them consumed two low and two high caloric meals. Paracetamol was mixed with a liquid meal and administered by a nasogastric feeding tube. The post prandial paracetamol plasma concentration time(More)
Recently, the conventional lifting scheme that is widely used for the construction of Wavelets and 2-channel filter banks has been extended to M-channel filter banks (M > 2). This extension brings up the beneficial properties of the lifting scheme to a broader range of applications, like discrete cosine transforms. There exist many hand-crafted(More)
