Cross-System Validation of Engagement Prediction from Log Files
Engagement is an important aspect of effective learning. Time spent using an e-Learning system is not quality time if the learner is not engaged. Tracking student disengagement wou...

Time Series Prediction by Perturbed Fuzzy Model
This paper presents a fuzzy system approach to the prediction of nonlinear time series and dynamical systems based on a fuzzy model that includes its derivative information. The u...

DARTS: Techniques and Tools for Predictably Fast Memory Using Integrated Data Allocation and Real-Time Task Scheduling
—Hardware-managed caches introduce large amounts of timing variability, complicating real-time system design. One alternative is a memory system with scratchpad memories which im...

Concepts From Time Series
This paper describes a way of extracting concepts from streams of sensor readings. In particular, we demonstrate the value of attractor reconstruction techniques for transforming ...

Branch Target Buffers: WCET Analysis Framework and Timing Predictability
—One step in the verification of hard real-time systems is to determine upper bounds on the worst-case execution times (WCET) of tasks. To obtain tight bounds, a WCET analysis h...
