On-Line Undergraduate Laboratories in Signal and Image Processing, Communications, and Controls @ Arizona State University
Engineering - Electrical (55)
Arizona State University is fully developing and evaluating a web-based undergraduate laboratory tool in the areas of undergraduate digital signal processing(DSP), communications, image processing and controls. We have already developed and successfully tested a prototype laboratory tool (J-DSP) for use in the undergraduate DSP class. This web-based prototype supports capabilities for online signal processing simulations and provides laboratory experiences to distance learning and on-campus undergraduate students. The tool is based on a collection of novel Java applets that support a user-friendly object oriented environment. This exemplary Java software supports a simulation environment that enables students to establish and execute experiments from any computer platform that is equipped with a web browser.
This work provides significant extensions of the laboratory prototype to the other areas (communications, image processing and controls), an assessment and dissemination strategy that includes test sites, and a plan to sustain development, dissemination, and evaluation after the CCLI project. The prototype lab and the proposed extensions represent perhaps the first comprehensive effort to provide on-line lab experiences in distance learning environments. We anticipate that this novel concept can be extended to different types of subjects at different levels of education, e.g., on-line experiments at levels and topics ranging from high-school physics to community college science labs and college-level engineering subjects. The prototype J-DSP along with its proposed extensions to "hot" systems topics such as communications, image processing, and advanced controls will enable new web-course developers to seamlessly integrate online experiments to their web-course content.

Igert: An Arts, Sciences and Engineering Research and Education Initiative For Experiential Media @ Arizona State University
This IGERT award at the Arts, Media and Engineering Program at Arizona State University will develop research and training mechanisms for the creation of a new class of media scientists. These scientists will produce new approaches for the integration of computational elements and digital media in the physical human experience. Their work will result in experiential media systems - hybrid physical-digital environments that address significant challenges in key areas of the human condition such as health, education and everyday living.
The knowledge required to create experiential media systems is currently fragmented across engineering, sciences and arts. This IGERT award will train a new generation of hybrid media engineers-scientists-artists who are equipped to transcend this fragmentation. The training will be realized through a large interdisciplinary network combining expertise from twelve contributing disciplines. This network will allow integrated advanced research in sensing, modeling, feedback, experiential construction and learning. The research will result in new knowledge in media systems as well as within each contributing area. It will also result in the development of large-scale applications of societal significance. The graduate training mechanisms are implemented through formally approved concentrations within the graduate degree programs of participating disciplines. They combine discipline specific education in one of the IGERT research areas with interdisciplinary training in media development. The framework of this IGERT allows for methodology found in the sciences to be combined with creativity found in the arts. It will bridge the gap between computation and the physical experience, advance human-centric technologies and produce major advances in education, rehabilitation, communication, and everyday living. IGERT is an NSF-wide program intended to meet the challenges of educating U.S. Ph.D. scientists and engineers with the interdisciplinary background, deep knowledge in a chosen discipline, and the technical, professional, and personal skills needed for the career demands of the future. The program is intended to catalyze a cultural change in graduate education by establishing innovative new models for graduate education and training in a fertile environment for collaborative research that transcends traditional disciplinary boundaries.

Collaborative Research: An Astronomical-Calibrated Time Scale For the Mesozoic Era @ Arizona State University
This collaborative project will assemble a continuous Astronomical Time Scale (ATS) for the Mesozoic Era (65 to 251 million years ago) from orbitally forced paleoclimate cycles recorded in stratigraphic data. The results should improve estimates of rates and timings of a wide range of Earth system processes by at least an order of magnitude. Project activities will be coordinated with more than a dozen international partners and will utilize the expertise of the Cretaceous, Jurassic, and Triassic subcommissions of the International Commission on Stratigraphy. The grand "team" goal is to extend the ATS, now virtually complete for the Cenozoic Era (0 to 65 million years ago), to encompass the past 250 million years. The methods that underpin the Cenozoic ATS will be applied to the Mesozoic. Emphasis will be placed on the goodness of fit of stratigraphic signals to astronomical models, duplication of records from different regions, and high-resolution calibration to geomagnetic polarity signatures and integrated bio- and chemostratigraphy. To aid in the science, a universally accessible signal processing toolbox will be created to modernize and unite leading statistical time series techniques used in cyclostratigraphic research, as well as in many other geoscience fields. Numerical ages from the reconstructed ATS will be inter-calibrated with other dating techniques in conjunction with NSF's EARTHTIME Project. All data and tools will be documented and accessible through multiple NSF public database systems, including GEON, CHRONOS, PaleoStrat, PBDB, and others. This project fulfills an ongoing global community initiative to develop a continuous, astronomical-calibrated, International Geologic Time Scale for the past quarter billion years of Earth history.

Biomedical Innovations Using Implementation-Aware Agile Sensing and Signal Processing @ Arizona State University
Title: Biomedical Innovations Using Implementation-Aware Agile Sensing and Signal Processing Abstract: Medical condition diagnosis is heavily based on sensor measurements and their processing. These measurements correspond to waveforms that propagate over the complex body environment and are transformed linearly or nonlinearly according to the characteristic environment properties. However, the medical community does not fully exploit the potentials of advanced processing matched to nonlinear structures or modern sensor technologies such as waveform agility that leads to significant estimation performance improvements. This research exploits advanced implementation-aware sensing and processing techniques to improve medical diagnosis by: (a) efficient processing using compressed sensing and nonlinear time-varying spectral methods; (b) estimation of environment descriptors and disease state parameters combined with waveform-agile sensing; and (c) mapping estimation and waveform-agile sensing algorithms onto field-programmable gate arrays. This framework brings revolutionary advances in diagnosing, treating, and tracking disease states that are otherwise difficult to obtain as advanced processing techniques are either not available or too costly. The investigators also design on-line software toolboxes with sensing experiments for use in outreach programs to recruit and retain freshmen and underrepresented student populations.
The research integrates advanced signal processing, stochastic Bayesian estimation, and waveform-agile sensing with implementation-aware algorithms to improve estimation of disease states. The investigators study time-frequency techniques matched to nonlinear structures to process biomedical data. Compressive sensing methodologies are developed that reduce the number of required measurements and allow for alternative computational algorithms. Mathematical descriptors are designed to model disease states using time-varying transfer functions. Sequential Bayesian techniques and waveform adaptation are used to estimate information. Algorithm reconstruction procedures are developed that trade high performance for reduced implementation cost. Finally, the investigators design algorithms cognizant of complexity and memory requirements.

Distributed and Robust Estimation For Cyberphysical Systems Using a Nonlinear Consensus Approach @ Arizona State University
Objective:
The objective of this project is to design and test nonlinear, robust, and power-aware consensus estimation algorithms for fully distributed cyber-physical systems (CPS). Systems that use a large number of networked sensors with limited transmission range due to power limitations are considered. Such systems have a large number of transmitters that are subject to non-Gaussian impulsive noise and network interference. Robust decentralized distributed sensing will be considered with joint design of the sensing and communication systems with low-power constraints.
Intellectual Merit:
The intellectual merit is in the novel design of distributed nonlinear consensus algorithms to solve parameter estimation problems for CPS applications. Proposed convergence analysis, and variance of the estimators in the presence of these nonlinearities go beyond existing analyses of linear approaches. The research will provide power-aware consensus estimation algorithms with minimal assumptions about the sensing and channel noise through judicious design of nonlinearities. Algorithms will be tested with photo-voltaic array data and a testbed will be developed to address and characterize real-time estimation.
Broader Impact:
The broader impacts are on alternative energy, environmental, infrastructure monitoring, and STEM education. The PIs will design educational software modules that use sensing as a paradigm to illustrate basic concepts in probability and communications at the undergraduate level. Dissemination and education efforts will include computer and mobile-based applications using the award-winning JAVA-DSP software packages. The investigators will also actively recruit students from under-represented minorities to work on the project.

Rapid: Collaborative Research: Covid-19 Hotspot Network Size and Node Counting Using Consensus Estimation @ Arizona State University
In order to open up the economy in light of the reality of COVID-19, a suite of solutions are needed to minimize the spread of COVID-19 which include providing tools for businesses to minimize the risk for their employees and customers. It is important to detect transmission hotspots where the contact between infected and uninfected persons is higher than average. This project will provide information to assess precisely the size, density and locations of COVID-19 hotspots and enable issuing well-informed advisories based on data-driven continuous risk assessment. Every step will be taken to ensure privacy and network security and specific algorithms will be developed for secure access and information transfer. The project will access databases at CDC, Johns Hopkins and the WHO, and create a comprehensive website to disseminate real-time localized COVID-19 hotspot data, while maintaining privacy. The project will create new algorithms and embed them in iOS and Android apps that will continuously interact with databases. The software for mobile devices as well as central hubs will be made publicly available through APIs for use by the broader community.
The project will use advanced consensus-based methods for estimating network area/size, node locations and node counts in a network based on minimal transmit-receive data. The proposed methods will lead to significant improvements compared to existing algorithms. The project will design consensus-based algorithms to estimate (a) the center, radius, and consequently, the size of the network, and (b) the number of users in the network. Localization algorithms will be designed that work with noisy and incomplete data. The proposed work is different from the contact-tracing technology used by Google and Apple which is limited to newer devices. The proposed algorithms and software will advance the state of the art while retaining compatibility with emerging and existing mobile technology. The project will help reduce COVID-19 infections and save lives. The research will also have applicability to other fields such as the E911 system, indoor user tracking, infrastructure-free implementations applicable to robotics, autonomous systems and vehicle fleets, and location-aware patient care and other mobile health applications. The developed algorithms can be used in other emergency situations, such as locating clusters of sheltering groups in the case of earthquakes and tsunamis, to assist first responders in finding survivors after an event, and for detection of transmission nodes in the case of future pandemics or future waves of COVID-19. Outreach activities will be integrated with the research and include the creation of software and web content for dissemination.

Ires Track 1: Sensor Information Processing and Machine Learning For Wearable Devices @ Arizona State University
This IRES project brings together advances in sensor devices with machine learning and digital signal processing (DSP) algorithms in an international research endeavor that promises to elevate precision in mobile and wearable technologies. Arizona State University (ASU) faculty and students will collaborate with the Dublin City University (DCU) Insight Center for Data Analytics, which has a synergistic relationship with ASU in several areas including sensors, analytics, machine learning (ML), wearables and Internet of Things (IoT). ASU brings expertise in flexible sensors, chemical and biosensors, statistical signal processing, bio-informatics, and machine learning. DCU brings expertise in data analytics, human activity monitoring, environmental monitoring, artificial intelligence, sensor analytics and big data analysis. IRES participating students will spend an immersive six-week summer program at the DCU Insight Center to actively improve their ML and sensor research skills; participants will produce and evaluate sensor analytics, and create algorithms and software for IoT, wearables and mobile health monitoring. Programs and workshops will be established to train IRES participants to skillfully and effectively present their research in international settings. Weekly presentations at the international site and guidance by international mentors will enrich the cohort’s professional experience. Embedding students in the DCU Insight center funded by European Union (EU) and Irish Science Foundation (ISF) grants will provide knowledge on EU and international research practices, ethics, standards and policies.
The goals of this project are to: a) advance the science of integrated design of sensors and machine learning algorithms, b) train and enable a diverse cohort of students to make research contributions in integrated sensing and ML for IoT systems, c) gain knowledge on international policies/standards of deploying AI, big data systems, and sensors, and d) provide experiences that broaden understanding of global practices and career options. This project is motivated by the fact that inexpensive sensors are required for IoT, mobile health and wearable systems; to achieve the requisite precision, sensor design must be accompanied by corrective ML and SP algorithms. IRES research therefore focuses on the overlap of new sensor device design and novel ML algorithm development. In terms of ML, one of the key objectives is to develop compact, low power algorithms adequate for integration with sensors and mobile devices. IRES project areas include flexible sensors, sensor information management, efficient deep learning, and big data analysis. Example research project applications include biomarker detection, big data processing, gait detection, and deep neural nets for sensor and IoT systems. Work will be disseminated via collaborative publications and presentations in international conferences and refereed journals. Industry engagement at the ASU SenSIP and DCU Insight centers will provide ongoing valuable feedback, and annual external evaluation will assess progress and outcomes across all IRES activities.
