A Petri Net-Based Approach To Reconfigurable Manufacturing Systems Modeling, Linda L. Zhang, Brian Rodrigues Jan 2009

A Petri Net-Based Approach To Reconfigurable Manufacturing Systems Modeling, Linda L. Zhang, Brian Rodrigues

Research Collection Lee Kong Chian School Of Business

Reconfigurable manufacturing systems (RMSs) have been used to provide manufacturing companies with the required capacities and capabilities, when needed. Recognizing (1) the importance of dynamic modeling and visualization in decision making support in RMSs and (2) the limitations of the existing studies, we model RMSs based on Petri net (PN) techniques with focus on the process of reconfiguring system elements while considering constraints and system performance. In response to the modeling difficulties identified, a new formalism of colored timed PNs is introduced. In conjunction with colored tokens and timing in colored PNs and timed PNs, we further define a reconfiguration …

Transportation and border security systems have a common goal: to allow law-abiding people to pass through security and detain those people who intend to harm. Understanding how intention is concealed and how it might be detected should help in attaining this goal. In this paper, we introduce a multidisciplinary theoretical model of intent concealment along with three verbal and nonverbal automated methods for detecting intent: message feature mining, speech act profiling, and kinesic analysis. This paper also reviews a program of empirical research supporting this model, including several previously published studies and the results of a proof-of-concept study. These studies …

Automatic, Multimodal Evaluation Of Human Interaction, Matthew L. Jensen, Thomas O. Meservy, Judee K. Burgoon, Jay F. Nunamaker Jr. Jan 2009

This article outlines an approach for automatically extracting behavioral indicators from video, audio, and text and explores the possibility of using those indicators to predict human-interpretable judgments of involvement, dominance, tension, and arousal. We utilized two-dimensional spatial inputs extracted from video, acoustic properties extracted from audio and verbal content transcribed from face-toface interactions to construct a set of multimodal features.Multiple predictive models were created using the extracted features as predictors and human-coded perceptions of involvement, tenseness, and arousal as the criterion. These predicted perceptions were then used as independent variables in classifying truth and deception. Though the predicted values for …

Social Or Academic Language Intervention? You Don’T Have To Choose, Lee Robinson Jan 2009

Social Or Academic Language Intervention? You Don’T Have To Choose, Lee Robinson

Faculty Publications

Students with a variety of types of language impairments exhibit deficits that affect both social interactions and academic performance. Two types of theory of mind underlie social and academic language skills: interpersonal and intrapersonal. In this article, the authors describe strategies for developing interpersonal and intrapersonal theory of mind abilities with the goal of promoting the inferencing skills essential for comprehension of social and academic language.

Assessment Centers At The Crossroads: Toward A Reconceptualization Of Assessment Center Exercises, Filip Lievens, Robert P. Tett, Deidra J. Schleicher Jan 2009

Assessment Centers At The Crossroads: Toward A Reconceptualization Of Assessment Center Exercises, Filip Lievens, Robert P. Tett, Deidra J. Schleicher

Research Collection Lee Kong Chian School Of Business

Exercises are key components of assessment centers (ACs). However, little is known about the nature and determinants of AC exercise performance. The traditional exercise paradigm primarily emphasizes the need to simulate task, social, and organizational demands in AC exercises. This chapter draws on trait activation theory in proposing a new AC exercise paradigm. First, we develop a theoretical framework that addresses the complexity of situational characteristics of AC exercises as determinants of AC performance. Second, we argue for planting multiple stimuli within exercises as a structured means of eliciting candidate behavior. Third, we show how the new paradigm also has …
