Mobile apps redistributing surplus food are receiving increased attention for their sustainability benefits. Nevertheless, there is limited research on the opportunities created businesses to penetrate Bottom of Pyramid (BoP) market. Drawing Service-Dominant (S-D) logic, affordance and means-end theories, this study investigates how waste mobile can support sustainable value co-creation at BoP....

We describe a novel recursive lter design technique for multi-scale \pyramid" transforms. The recursion in the design technique follows that of the pyramid construction, and allows us to solve a reduced design problem at each step. We demonstrate the use of this technique by designing lters of various orientation bandwidths for use in a \steerable pyramid" image transform.1

In this work, we present a registration framework for cardiac cine MRI (cMRI), tagged (tMRI) and delay-enhancement MRI (deMRI), where the two main issues to find an accurate alignment between these images have been taking into account: the presence of tags in tMRI and respiration artifacts in all sequences. A steerable pyramid image decomposition has been used for detagging purposes since it is...

We present ERSS 2005, our entry to this year’s DUC competition. With only slight modifications from last year’s version to accommodate the more complex context information present in DUC 2005, we achieved a similar performance to last year’s entry, ranking roughly in the upper third when examining the ROUGE-1 and Basic Element score. We also participated in the additional manual evaluation base...

A distributed counter is a concurrent object which provides a fetch-and-increment operation on a shared value. On the basis of a distributed counter, one can implement various fundamental data structures, such as queues or stacks. We present the counting pyramid, an efficient implementation of a distributed counter in a message passing system, which is based on software combining. The counting ...

This paper represents Hybrid model image fusion algorithm based on combination of pyramid method and Wavelet method .To improve the Quality of output image an Algorithm is proposed by using Laplacian pyramid and Gradient pyramid methods from pyramid method and, Haar wavelet from Wavelet method. This algorithm creates new images for further image processing applications like Enhancement, Segment...

The proposed scheme of pyramid broadcasting is a new way of rendering Video On Demand service at metropolitan scale. In pyramid broadcasting, the most frequently requested movies are multiplexed on the broadcast network, resulting in radical improvement of access time and e cient bandwidth utilization. We provide analytical and experimental evaluations of pyramid broadcasting based on its imple...

Recently, we presented a new image pyramid, called the Riesz pyramid, that uses the Riesz transform to manipulate the phase in non-oriented sub-bands of an image sequence to produce real-time motion-magnified videos. In this report we give a quaternionic formulation of the Riesz pyramid, and show how several seemingly heuristic choices in how to use the Riesz transform for phase-based video mag...

In this paper we introduce a new type of Pascal’s pyramids. The new object is called hyperbolic Pascal pyramid since the mathematical background goes back to the regular cube mosaic (cubic honeycomb) in the hyperbolic space. The definition of the hyperbolic Pascal pyramid is a natural generalization of the definition of hyperbolic Pascal triangle ([2]) and Pascal’s arithmetic pyramid. We descri...

Early ecologists identified a pyramidal trophic structure in terms of number, biomass and energy transfer. In 1943, the psychologist Maslow put forward a pyramid model to describe layers of human needs. It is indicated that the pyramid principle is universally applicable in natural, humanistic and social disciplines. Here, we report that a pyramid structure also exists in urban public health (U...
