Advancing Chart Question Answering with Robust Chart Component Recognition
The task of comprehending charts [1, 2, 3] presents significant challenges for machine learning models due to the diverse and intricate shapes of charts. The chart extraction task ensures the precise identification of key components, while the chart question answering (ChartQA) task integrates …

Message sequence chart specifications with cross verification
… specifications written with Message Sequence Charts and State Transition Diagrams.;In this work an algorithm is proposed in which all conditional MSCs are transformed into an algebraic representations, Message Flow Graphs and by stepwise refinement, a Global State Transition Graph is created. …

A robust Shewhart control chart adjustment strategy
The standard Shewhart control chart for monitoring process stability is generalized by selecting a point in time at which the distance between the control limits is reduced. Three cost models are developed to describe the total cost per unit time of monitoring the mean of a process using both the …

Using Live Sequence Chart Specifications for Formal Verification
… on investigating the use of Live Sequence Charts (LSCs), a graphical and intuitive language directly suited for expressing communication behaviors of a system as the specification language for a system under test. The research presents two methods for using LSCs as a specification language: …

VisText: A Benchmark for Semantically Rich Chart Captioning
Captions that describe or explain charts help improve recall and comprehension of the depicted data and provide a more accessible medium for people with visual disabilities. However, current approaches for automatically generating such captions struggle to articulate the perceptual or cognitive …

Control chart procedures based on cumulative gauging scores
Control charts based on cumulative gauging scores rely on gauge scoring systems used for transforming actual observations into integer gauging scores. In some cases, the gauging scores are easy to obtain by using a mechanical device such as in the go-no-go inspection process. Thus, accurate …

The Minimax control chart for multivariate quality control
A new multicharacteristic control chart designed to detect shifts in the mean of a multivariate process is proposed. It is assumed that the correlation matrix is known and that the distribution of the data is multivariate normal. The new chart is based on the minimum standardized sample mean …

Retrospective chart review of surgical patients and chronic pain
… nature of CPSP by creating a retrospective chart review of surgical patients to understand standard demographics, preexisting health conditions, and surgical factors that may increase the incidence of CPSP. METHODS: This study focused on exploring the incidence of CPSP in two distinct …

VisuaLint: Sketchy In Situ Annotations of Chart Construction Errors
Chart construction errors, such as truncated axes or inexpressive visual encodings, can hinder reading a visualization, or worse, imply misleading facts about the underlying data. These errors can be caught by critical readings of visualizations, but readers must have a high level of data and …

A variable sampling interval chart for a combined statistic
… is an extension of the work on variable sampling charts (<i>VSI</i>) for monitoring a single parameter. An attempt is made to develop a chart which can simultaneously monitor both the process mean and process variance. The chart is based on a statistic which combines both mean and variance. After …

Chart Question Answering with an Universal Vision-Language Pretraining Approach
Charts are widely used for data analysis, providing visual representations and insights into complex data. To facilitate chart-based data analysis using natural language, several downstream tasks have been introduced recently including chart question answering. However, existing methods for these …

Meeting Joint Commission Compliance by Improving the Chart Audit Process
… in the nursing documentation of patients’ charts. In order to do so, a redesign of their current chart auditing system needed to occur to take the process from pen and paper to an electronic database where the data gathered from the audit could be disseminated. The quality improvement team …

A Performance Analysis of the Minimax Multivariate Quality Control Chart
… analysis of three different Minimax control charts is performed with respect to their Chi-Square control chart counterparts under several different conditions. A unique control chart must be constructed for each process described by a unique combination of quality characteristic mean vector …
