Complex models created from isosurface extraction or CAD and highly accurate 3D models produced from high-resolution scanners are useful, for example, for medical simulation, Vir­ tual Reality and entertainment. Often models in general require some sort of manual editing before they can be incorporated in a walkthrough, simulation, computer game or movie. The visualization challenges of a 3D ed...

This study set out to investigate the effect of peer- editing as a metacognitive strategy on the development of writing. It was hypothesized that peer-editing could be used to raise grammatical and compositional awareness of the learners. Forty pre-intermediate sophomores at Islamic Azad University-Tabriz Branch participated in the study, taking the course Writing I. To warrant the initial homo...

In this paper, we discuss wearable interfaces for a computational memory-aid useful in everyday life. The aim of this research is to develop an albuming system for augmenting human memory. SARA, a framework for augmented memory systems, provides users with four types of functions: Memory Retrieval, Memory Exchange, Memory Transportation, and Memory Editing. To be equipped with various strategie...

OWEN is an interactive tool for aligning two long DNA sequences that represents similarity between them by a chain of collinear local similarities. OWEN employs several methods for constructing and editing local similarities and for resolving conflicts between them. Alignments of sequences of lengths over 10(6) can often be produced in minutes. OWEN requires memory below 20 L, where L is the su...

This paper describes the assessment of MAPS (Memory Aiding Prompting System), a system that provides task support prompting to support independence for persons with cognitive disabilities and caregivers. MAPS consists of a handheld prompter and a multimedia editing tool for task script creation, storage, and modification. The need for ethnographic tool use is discussed and a short sub-set of th...

This paper addresses the problem of reliably measuring productivity gains by professional translators working with a machine translation enhanced computer assisted translation tool. In particular, we report on a field test we carried out with a commercial CAT tool in which translation memory matches were supplemented with suggestions from a commercial machine translation engine. The field test ...

This paper aims to survey the current state of research, development and use of Machine Translation (MT). Under ‘research’ the role of linguistics is discussed, and contrasted with research in ‘analogybased’ MT. The range of languages covered by MT systems is discussed, and the lack of development for minority languages noted. The new research area of spoken language translation (SLT) is review...

Sparse Voxel Directed Acyclic Graphs (SVDAGs) are an efficient solution for storing high-resolution voxel geometry. Recently, algorithms the interactive modification of SVDAGs have been proposed that maintain compressed geometric representation. Nevertheless, attributes, such as colours, require uncompressed storage, which can result in high memory usage over course application. The reason is c...

Capturing and rendering of real scenes in an immersive virtual environment is still a challenging task. In this paper we present a novel workflow, which emphasizes high-quality, view-dependent projective texturing at low memory cost, while allowing artist intervention to ensure image quality control. First, a small set of photographs of a real scene are used to create a 3D model, using standard...
