Verbal interviews performed by trained clinicians are a common form of assessments to measure cognitive decline. The aim in this paper is to study the usability of automated methods for evaluating verbal cognitive status assessment tests for the elderly. If reliable, such methods for cognitive assessment can be used for frequent, non-intrusive, low-cost screenings and provide objective and long...

Geometric resolution is one of several performance criteria which have to be considered when evaluating and comparing diierent scanners. This paper describes a strategy how to investigate the geometric scanner resolution, in particular for high performance lm scanners. For reasons of objectivity and investigation speed these testing procedures are automated as far as possible. We compare visual...

The U.S. armed services are widely adopting simulation-based training, largely to reduce costs associated with live training. Ideally, instructors would observe each individual within the context of team performance and provide instruction based on observed misunderstandings, inefficient task execution, ineffective or inappropriate actions and so forth. However, it is impossible for instructors...

based model describing the processes of interception, infiltration, surface runoff, and erosion from small agricultural and urban watersheds (Smith et al., 1995). In this model, watersheds are represented by subdividing contributing areas into a cascade of one-dimensional overland flow and channel elements using topographic information. A broadly updated version of KINEROS, KINEROS2 may be used...

Automated essay scoring (AWE) software, which uses artificial intelligence to evaluate essays and generate feedback, has been seen as both a boon and a bane in the struggle to improve writing instruction. We used interviews, surveys, and classroom observations to study teachers and students using AWE software in 4 secondary schools. We found AWE to be a modest addition to the arsenal of teachin...

This document contains a short summary of results, achieved using the alternative skills assessment system developed for Mobile Education Center. The system was designed as client-server application and can be used for automated examination of practical skills and knowledge in the area of digital systems design and modelling using VHDL. The communication in Mobile Education Center is based on w...

Introduction: Flow artifacts in MR images can appear as image ghosts within and outside the body cavity. Technical improvements aimed at suppressing these image ghosts often rely on expert scoring (1,2) or on semi-automated methods demanding tissue segmentation and estimation of statistical properties of intensity distribution (3) to evaluate the efficacy of the methods. These approaches can be...

Middleware for Web service compositions, such as BPEL engines, provides the execution environment for services as well as additional functionalities, such as monitoring and self-tuning. Given its role in service provisioning, it is very important to assess the performance of middleware in the context of a Serviceoriented Architecture (SOA). This paper presents SOABench, a framework for the auto...

A system is described which automatically identifies cephalometric landmarks on digital cephalometric radiographs. The accuracy of the automated system in identifying nineteen cephalometric landmarks is assessed. The accuracy obtained with the automated system is less than that of manual tracing. The automated system has particular difficulty in identifying landmarks which lie on poorly defined...

In this thesis, we investigate automated assessment (AA) systems of free text that automatically analyse and score the quality of writing of learners of English as a second (or other) language. Previous research has employed techniques that measure, in addition to writing competence, the semantic relevance of a text written in response to a given prompt. We argue that an approach which does not...
