We propose an ultra high frequency (UHF) radio frequency identification (RFID, 902-928 MHz in the US) channel emulation testbed that is capable of simultaneously emulating unique wireless channels. The proposed system can potentially be an invaluable tool in the design and validation of RFID-based Internet of Things (IoT) sensors and systems. Emula...
Conference Paper
Wearable sensors with RFID (Radio Frequency Identification) tags are considered to be an integral part of the upcoming revolution in the IoT (Internet of Things) sector. As with many deployed IoT sensor systems, dynamic environment conditions present challenges in reliably measuring system performance; this difficulty is enhanced due to proprietary...
Chapter
The discovery of the applicability of radio-frequency identification (RFID) for inductive coupling to a stretchable fabric antenna has enabled biomedical sensing applications using wearable, passive, unobtrusive smart garment devices. Stretching of knitted fabric antennas embedded into wearable garments allows correlation of physical properties of...
Conference Paper
Future advances in the medical Internet of Things (IoT) will require sensors that are unobtrusive and passively powered. With the use of wireless, wearable, and passive knitted smart garment sensors, we monitor infant respiratory activity. We improve the utility of multi-tag Radio Frequency Identification (RFID) measurements via fusion learning acr...

Low-energy battery-less passive RFID (Radio Frequency Identification) tags will be an integral part of the upcoming IoT (Internet of Things) revolution. Applications for such tag-systems include medical applications, inventory management, security, localization, household application, etc. Currently, there is a growing demand for passive RFID-based...
Conference Paper
With the use of a wireless, wearable, passive knitted smart fabric device as a strain gauge sensor, the proposed algorithm can estimate biomedical feedback such as respiratory activity. Variations in physical properties of Radio Frequency Identification (RFID) signals can be used to wirelessly detect physiological processes and states. However, it...
Conference Paper
Using a wearable electromyography (EMG) and an accelerometer sensor, classification of subject activity state (i.e., walking, sitting, standing, or ankle circles) enables detection of prolonged "negative" activity states in which the calf muscles do not facilitate blood flow return via the deep veins of the leg. By employing machine learning classi...
Conference Paper
The Nifty Assignments special session is all about promoting and sharing the ideas and ready-to-use materials of successful assignments. Each presenter will introduce their assignment, give a quick demo, and describe its niche in the curriculum and its strengths and weaknesses. The presentations (and the descriptions below) merely introduce the ass...

Utilizing passive Radio Frequency Identification (RFID) tags embedded in knitted smart-garment devices, we wirelessly detect the respiratory state of a subject using an ensemble-based learning approach over an augmented Kalman filtered time-series of RF properties. Methods: We propose a novel approach for noise modeling using a "reference tag," a...
Conference Paper
Radio Frequency Identification (RFID) technology is often deployed for inventory management scenarios. In inventory applications, a known or unknown number of RFID tags are queried in a discrete manner and for a single, short period of time, until each tag is recognized by the interrogator device. Passive RFID provides several benefits conducive to...
Conference Paper
Signal processing of time-series properties of Radio Frequency Identification (RFID) tags and novel work in textile knitted antennas for garment devices have enabled real-time detection of motion-based artifacts through unobtrusive, wireless, wearable devices. Capturing the Received Signal Strength Indicator (RSSI) as a time-series signal, we class...
Conference Paper
We have applied passive Radio Frequency Identification (RFID), typically used for inventory management, to implement a novel knit fabric strain gauge assembly using conductive thread. As the fabric antenna is stretched, the strength of the received signal varies, yielding potential for wearable, wireless, powerless smart-garment devices based on sm...
Article
Recent advancements in conductive yarns and fabrication technologies offer exciting opportunities to design and knit seamless garments equipped with sensors for biomedical applications. In this paper, we discuss the design and application of a wearable strain sensor, which can be used for biomedical monitoring such as contraction, respiration, or l...
Conference Paper
We describe an "unplugged" activity that exposes data structures and algorithms involved in image representation and compression, using multi-colored Post-It Notes®. We use Post-It's to illustrate how color images can be encoded and decoded so they can be stored efficiently on a computer and/or transmitted efficiently across a network. This provide...
Conference Paper
Wearable smart devices have become ubiquitous, with powered devices capable of collecting real-time biometric information from its users. Typically, these devices require a powered component to be worn and maintained, such as a battery-powered sensor, Bluetooth communications device, or glasses. Pregnancy and infant monitoring devices may be uncomf...
Conference Paper
Educating STEM students in the techniques of massively parallel computing anticipates a growing current and future need for scientists, engineers, and analysts who are facile with Big Data. Using very low cost hardware (Raspberry Pi) and free software (Hadoop) we are exposing students to distributed computing while limiting expense. We anticipate t...
Conference Paper
This session invites educators interested in sharing and/or learning about experiences with tools for automatic feedback on technical work: the "if", "why" and "how". This includes experiences with program testing, problem-solving exercises, or quizzes, generated or checked with engines with expert-level technical capabilities, to scale up feedback...
Article
The recent growth of agent-based software systems was achieved without the development of a reference architecture. From a software engineering standpoint, a reference architecture is necessary to compare, evaluate, and integrate past, current, and future agent-based software systems. The agent systems reference architecture (ASRA) advances the age...
Article
We describe our experience in teaching an integrated module in networks, mathematics, and cryptography, suitable for high school students. The objective is to design a lesson with minimal prerequisite background and a varying degree of programming experience, with an aim towards exciting students early on about computing. Students create and implem...

The slow adoption of agent-oriented methodologies as a paradigm for developing industry systems is due in part to their lack of integration and general-purpose use. There exists a need to define common patterns, relationships between components, and structural qualities that a reference architecture for agent-based systems would solve. However, the...

Agent-based systems have been the object of intense research over the past decade. While great theoretical progress has been made, the software frameworks for creating agent-based systems offer considerable variability in their capabilities and functionality. This paper introduces a reference model for agent-based systems. The purpose of a referenc...

Since the 1960's, Computer Assisted Instruction (CAI) has been promoted as the new standard for teaching and learning. Schools were provided with computers and internet connections at an astounding rate in the 1990's, but there was no correlated increase in student performance. 1 Investigation into this problem has revealed that computer technology...

Agent systems are unique in their design and functionality; as such, they require unique techniques to pro- file, reverse engineer, test, and secure. The Agent Systems Reference Model (ASRM) provides a standard for the development and deployment of agent systems. To support the informed construction of the ASRM, we explored existing techniques for...

The current state of the art in agent technology sees that several implementations of agent frameworks exist. However, there is lit- tle agreement on the terms and concepts used to describe such sys- tems, which is a significant barrier towards adoption of these tech- nologies by industry, military and commercial entities. A clear def- inition of t...
