BACKGROUND Different visual acuity chart can be targeted to evaluate the visual function of patients with different eye diseases. We conducted a comparative analysis of the digital logarithm of the minimum angle of resolution (LogMAR) vision chart and the standard logarithmic vision chart for the measurement of visual acuity after retinal detachment surgery. METHODS We used the digital LogMAR...

OBJECTIVES To evaluate the feasibility, applicability and the value of customised symphysio fundal height (SFH) charts developed for women of Indian origin in the United Kingdom (UK: CSFH - In chart) and women of African origin in the UK (CSFH - Af chart) in detecting fetal growth restriction and predicting low birth weight (LBW) of the neonate in a Lankan population, and to compare these resul...

The attribute Conforming Run Length (CRL) control chart has attracted increasing research interests in Statistical Process Control (SPC). It decides the process status based on the interval or distance between two nonconforming units. This article proposes a Generalized CRL chart (namely GCRL chart) for monitoring the mean of a measurable quality characteristic x under 100% inspection. To run a...

This paper will present a generalisation of chart parsing able to cope with the case where the object being parsed is a particular kind of diagram (a flowgraph) and the grammar is an appropriate type of graph grammar (a flowgraph grammar). A feature that often occurs in such diagrams is structure sharing. This paper also discusses the problem of diagram recognition in the case where structure s...

This paper presents an algorithm for incremental chart parsing, outlines how this could be embedded in an interactive parsing system, and discusses why this might be useful. Incremental parsing here means that input i8 analysed in a piecemeal fashion, in particular allowing arbitrary changes of previous input without exhaustive reanalysis. Interactive parsing means that the analysis process is ...

Introduction In the field of linguistics, Active Chart Parsing (ACP) is an algorithm that generates all possible parsings of a sentence, given an ambiguous grammar. Therefore, ACP would be one part of a natural language interface to a database server, if real-time processing could be achieved. Parallel processing is one way to achieve real-time performance. A previously reported parallelization...

This work explores the problem of incremental analysis in the context of chart parsing, probably the most commonly used framework for the analysis of natural language. Incrementality here means that syntax correctness of a text is checked dynamically as the text is edited, changing the internal representation of the analysis rather than generating an entirely new one. This implies that the syst...

In this paper, we introduce a system that aims at recognizing chart images using a model-based approach. First of all, basic chart models are designed for four different chart types based on their characteristics. In a chart model, basic object features and constraints between objects are defined. During the chart recognition, there are two levels of matching: feature level matching to locate b...

Different acoustic variables such as pitch, volume, timbre and position can be used to represent quantitative, qualitative and categorical aspects of the information. Such sonifications are particularly useful for those with visual impairments; they are also beneficial in circumstances where visual representations would be impossible to use or to enrich a graphical realization. We demonstrate m...
