Slotting allowances, which are lump-sum transfers paid by food manufacturers to grocery retailers in return for various retail concessions, are becoming increasingly common in wholesale grocery markets. This article extends the literature on slotting allowances by considering two features that previously have been ignored: the role of food processors in determining these pricing arrangements, a...

The surgery of fractured bones is often a very complex problem. That is the reason why it would be beneficial to create a geometric and mechanic model of the bones before surgical intervention. The model geometry is based on the CT images of the patient and the known physical properties of the bone. A computerised system is presented here, called MedEdit, which helps a surgeon plan an operation...

OLAP (Online Analysis Processing) applications have very special requirements to the underlying multidimensional data that differs significantly from other areas of application (e.g. the existence of highly structured dimensions). In addition, providing access and search among multiple, heterogeneous, distributed and autonomous data warehouses, especially web warehouses, has become one of the l...

We analyze two parallel finite element implementations of the 2D time-dependent advection diffusion problem, one for multi-core clusters and one for CUDA-enabled GPUs, and compare their performances in terms of time and energy consumption. The parallel CUDA-enabled GPU implementation was derived from the multi-core cluster version. Our experimental results show that a desktop machine with a sin...

A miniaturized square resonator bandpass filter with circular stubs was designed, fabricated, and characterized. Analytical calculations were carried out to determine the critical filter parameters and the design was optimized using a 3D electromagnetic finite-element solver. The measured results were in good agreement with the designed results. The proposed filter exhibits significant improvem...

In contrast to 2D scatterplots, the existing 3D variants have the advantage of showing one additional data dimension, but suffer from inadequate spatial and shape perception and therefore are not well suited to display structures of the underlying data. We improve shape perception by applying a new illumination technique to the pointcloud representation of 3D scatterplots. Points are classified...

This paper discusses the design and implementation of a Pythonbased toolset to aid in assessing the response of the UK’s Advanced Gas Reactor nuclear power stations to earthquakes. The seismic analyses themselves are carried out with a commercial Finite Element solver, but understanding the raw model output this produces requires customised post-processing and visualisation tools. Extending the...

Knowledge embedded in a data stream is likely to be changed as time goes by. Identifying the recent change of the knowledge quickly can provide valuable information for the analysis of the data stream. However, most mining algorithms over a data stream are not able to extract the recent change of knowledge in a data stream adaptively. This is because the obsolete information of old data element...

$ The corresponding author, Member, IEEE and IEEE Computer Society Abstract: In this paper, we first develop a parallel algorithm for prefix computation on an n × n mesh of trees (MOT). For n data elements, the algorithm requires 4 log n + O(1) time using n2 processors. Using the MOT prefix, we next propose a prefix algorithm on an n × n OTIS mesh of trees. This algorithm for n4 data elements i...
