Visualizing Anomalous Activity in the Movement of Critical Infrastructure Employees

Visualizing Anomalous Activity in the Movement of Critical Infrastructure Employees

ABSTRACT The paper presents an approach to the movement analysis of the employees of critical infrastructure based on combination of data-mining and visualizations techniques. It consists of two stages – finding groups of employees with similar behavior and detection of the anomalies. The groups of similarities are defined using Kohonen self-organizing map (SOM); spatiotemporal patterns […]

A Smartphone Application for Location Recording and Rescue Request Using Twitter

A Smartphone Application for Location Recording and Rescue Request Using Twitter

ABSTRACT A prototype of an Android smartphone application named “T-support” is presented in this study. This application enables supported users (elderly, handicapped people, or children) who needs daily support to share their location coordinates via Twitter. Supporting users (families, neighbors, or relatives of the supported user) can then check the location coordinates of the supported […]

Orientation and Displacement Detection for Smartphone Device Based IMUs

Orientation and Displacement Detection for Smartphone Device Based IMUs

ABSTRACT Commonly, navigation uses GPS signals to determine location. In addition, GPS data can be collected over time to determine path taken. In spite of the ubiquity of GPS signals on the earth’s surface, there are certain locations where GPS signals are not available, such as inside a buildings or tunnels. Therefore, to determine accurate […]

Privacy-Preserving Learning Analytics: Challenges and Techniques

Privacy-Preserving Learning Analytics: Challenges and Techniques

ABSTRACT Educational data contains valuable information that can be harvested through learning analytics to provide new insights for a better education system. However, sharing or analysis of this data introduce privacy risks for the data subjects, mostly students. Existing work in the learning analytics literature identifies the need for privacy and pose interesting research directions, […]

Combining University Student Self-regulated Learning Indicators and Engagement with Online Learning Events to Predict Academic Performance

ABSTRACT Self-regulated learning theories are used to understand the reasons for different levels of university student academic performance. Similarly, learning analytics research proposes the combination of detailed data traces derived from technology-mediated tasks with a variety of algorithms to predict student academic performance. The former approach is designed to provide meaningful pedagogical guidance, while the […]

Estimation of Passenger Route Choice Pattern Using Smart Card Data for Complex Metro Systems

Estimation of Passenger Route Choice Pattern Using Smart Card Data for Complex Metro Systems

ABSTRACT Metro systems play an important role in meeting the demand for urban transportation in large cities. The understanding of passenger route choice is critical for public transit management. The wide deployment of automated fare collection (AFC) systems opens up a new opportunity. However, only each trip’s tap-in and tap-out time stamp and stations can […]

Embedding Spatio-temporal Information into Maps by Route-Zooming

Embedding Spatio-temporal Information into Maps by Route-Zooming

ABSTRACT Analysis and exploration of spatio-temporal data such as traffic flow and vehicle trajectories have become important in urban planning and management. In this paper, we present a novel visualization technique called route-zooming that can embed spatio-temporal information into a map seamlessly for occlusion-free visualization of both spatial and temporal data. The proposed technique can […]
