Wearable Sensor-Based Location-Specific Occupancy Detection in Smart Environments
(Hindawi, 2018)Occupancy detection helps enable various emerging smart environment applications ranging from opportunistic HVAC (heating, ventilation, and air-conditioning) control, effective meeting management, healthy social gathering, ... -
DeActive: Scaling Activity Recognition with Active Deep Learning
(ACM, 2018)Deep learning architectures have been applied increasingly in multi-modal problems which has empowered a large number of application domains needing much less human supervision in the process. As unlabeled data are abundant ... -
UnTran: Recognizing Unseen Activities with Unlabeled data using Transfer Learning
(IEEE, 2018)The success and impact of activity recognition algorithms largely depends on the availability of the labeled training samples and adaptability of activity recognition models across various domains. In a new environment, ... -
Forecasting Gas Usage for Big Buildings using Generalized Additive Models and Deep Learning
(IEEE, 2018)Time series behavior of gas consumption is highly irregular, non-stationary, and volatile due to its dependency on the weather, users’ habits and lifestyle. This complicates the modeling and forecasting of gas consumption ... -
A Flash Flood Categorization System using Scene-Text Recognition
(IEEE, 2018)Detecting flash floods in real-time and taking rapid actions are of utmost importance to save human lives, loss of infrastructures, and personal properties in a smart city. In this paper, we develop a low-cost low-power ... -
Evaluating Disaster TIme-Line from Social Media with Wavelet Analysis
—For over a decade, social media has proved to be a functional and convenient data source in the Internet of things. Social platforms such as Facebook, Twitter, Instagram, and Reddit have their own styles and purposes. ... -
Classifying Eyes-Free Mobile Authentication Techniques
(Journal of Information Security and Applications (JISA), 2018-06)Mobile device users avoiding observational attacks and coping with situational impairments may employ techniques for eyes-free mobile unlock authentication, where a user enters his/her passcode without looking at the device. ... -
Firearm Detection Using Wrist Worn Tri-Axis Accelerometer Signals
Gunshot detection traditionally has been a task performed with acoustic signal processing. While this type of detection can give cities, civil services and training institutes a method to identify specific locations of ... -
How Do We Talk Ourselves Into These Things? Challenges with Adoption of Biometric Authentication for Expert and Non-Expert Users
(ACM, 2018)Biometric authentication offers promise for mobile security, but its adoption can be controversial, both from a usability and security perspective. We describe a preliminary study, comparing recollections of biometric ... -
Towards Supporting Mobile Device Users Facing Severely Constraining Situational Impairments
(ACM, 2018)A subset of “Situationally Induced Impairments and Disabilities” (SIID), termed “Severely Constraining Situational Impairments” (SCSI), was explored at the user task and motivational level, to better understand the challenges ... -
Automatically Infer Human Traits and Behavior from Social Media Data
(2018)Given the complexity of human minds and their behavioral flexibility, it requires sophisticated data analysis to sift through a large amount of human behavioral evidence to model human minds and to predict human behavior. ... -
Recent trends in machine learning for human activity recognition—A survey
(Wiley, 2018)There has been an upsurge recently in investigating machine learning techniques for Activity Recognition (AR) problems as that have been very effective in extracting and learn-ing knowledge from the activity datasets. The ... -
Enhancing spatial query results using semantics and multiplex networks
(HETERONAM, 2018)Geographic information retrieval (GIR) research mainly focuses on finding relevant geographic artifacts along one layer, although answers to queries should preferably include artifacts across multiple layers.This paper ... -
Automated Detection of Substance Use-Related Social Media Posts Based on Image and Text Analysis
(IEEE, 2017)Abstract—Nowadays, teens and young adults spend a significant amount of time on social media. According to the national survey of American attitudes on substance abuse, American teens who spend time on social media sites ... -
A Comparison of Big Data Application Programming Approaches: A Travel Companion Case Study
(IEEE, 2017)With advances of big data technologies, there are many possible ways to program for each big data application. A challenge is to know the differences of the program approaches and decide which programming approach is the ... -
Towards Understanding Connections between Security/Privacy Attitudes and Unlock Authentication
(USEC, 2018)In this study, we examine the ways in which user attitudes towards privacy and security relating to mobile devices and the data stored thereon may impact the strength of unlock authentication, focusing on Android's graphical ... -
Behavioral Health Management of Space Dwelling Groups: Safe Passage Beyond Earth Orbit
(Originally published by: The Behavior Analyst Today, 2010)Plans to pursue space expeditionary missions beyond Earth orbit have occasioned renewed concern that crew behavioral health and performance effectiveness, along with spacecraft habitability, will present major challenges ... -
Behavior Analysis of Team Performance: A Case Study of Membership Replacement
(Originally published by: The Behavior Analyst Today, 2010)A three-person team performance task (TPT) is described, and evaluative results are presented under conditions of individual fixed ratios required to complete a work component and a team fixed ratio required to complete ... -
Programmed instruction for teaching Java: Consideration of learn unit frequency and rule-test Performance
(Originally published by: The Behavior Analyst Today, 2010)At the beginning of a Java computer programming course, nine students in an undergraduate class and nine students in a graduate class completed a web-based programmed instruction tutoring system that taught a simple computer ...
