We present a survey of techniques for the reduction of streaking artefacts caused by metallic objects in X-ray Computed Tomography (CT) images. A comprehensive review of the existing state-of-the-art Metal Artefact Reduction (MAR) techniques, drawn predominantly from the medical CT literature, is supported by an experimental comparison of twelve MAR techniques. The experimentation is grounded i...

A prepolarized MRI (PMRI) scanner was used to image near metal implants in agar gel phantoms and in in vivo human wrists. Comparison images were made on 1.5- and 0.5-T conventional whole-body systems. The PMRI experiments were performed in a smaller bore system tailored to extremity imaging with a prepolarization magnetic field of 0.4 T and a readout magnetic field of 27-54 mT (1.1-2.2 MHz). Sc...

Much remains to be done before agricultural trade is as liberal as world trade in manufactures. But agriculture is distorted by more than agricultural policies. In developing countries especially, farming is discouraged not only by farm protection policies in high-income countries but also by those countries' own manufacturing policies and distortions to services markets. This paper explores th...

This paper proposes an automatic acquisition method for preparation roles (PRs) and utilization roles (URs), which are analogues of agentive and telic roles in Generative Lexicon Theory. URs roughly express the purpose and function of a given object, and are defined as paraphrases of expressions such as “using an object” or “enjoying an object.” A PR of an object is defined as an expression ref...

Purpose – The purpose of this paper is to highlight undergraduates as an emergent student–scholar author group and to encourage institutions to take a future-oriented view, focusing greater attention to and support of undergraduate’s publishing. Design/methodology/approach – Highlighting benefits derived from undergraduate research (UR) experiences and publishing taken from the literature and e...
