Mari Buche Is Co-author of Article in ACM SIGMIS Database

Published September 5, 2019

By Karen Johnson

Mari Buche (DataS), School of Business and Economics associate dean and professor of management information systems, is co-author of the article, “He Said, She Said: Communication Theory of Identity and the Challenges Men Face in the Information Systems Workplace,” which was published in the August 2019 issue of the newsletter ACM SIGMIS Database: the DATABASE for Advances in Information Systems.

Co-authors of the article are Cynthia K. Riemenschneider, Baylor University, and Deb Armstrong, Florida State University.

Abstract: The preponderance of the academic research focused on diversity in the IS field has emphasized the perspectives of women and racioethnic minorities. Recent research has found that following the appointment of a female CEO, white male top managers provided less help to colleagues, particularly those identified as minority-status (McDonald, Keeves, & Westphal, 2018). Additionally, Collison and Hearn (1994) assert that white men’s universal status and their occupancy of the normative standard state have rendered them invisible as objects of analysis. To develop a more holistic view of the IS workplace, we expand the academic exploration by looking at the challenges men face in the Information Systems (IS) workplace. Using a cognitive lens, we evoke the challenges men perceive they face at work and cast them into revealed causal maps. We then repeat the process evoking women’s perspectives of men’s challenges. The findings are analyzed using the Communication Theory of Identity (CTI) to determine the areas of overlap and identity gaps. This study advances our understanding of the cognitive overlap (and lack thereof) regarding the challenges facing men in the IS field, and provides another step toward developing a more inclusive IS work environment.

By Karen Johnson

Keith Vertanen, assistant professor of computer science (HCC), and Scott Kuhl (HCC), associate professor of computer science, are principal investigators of a recently funded three-year National Science Foundation grant for their project, “CHS: Small: Rich Surface Interaction for Augmented Environments.” The expected funding over three years is $499,552.00.

Vertanen and Kuhl are members of Michigan Tech’s Institute of Computing and Cybersystems (ICC) Center for Human-Centered Computing. A 2018 ICC research seed grant funded by ECE Alumnus Paul Williams was used to produce some of the preliminary results in the successful proposal. More info about the Williams Seed Grant can be found here: https://blogs.mtu.edu/icc/2019/07/16/appropriating-everyday-surfaces-for-tap-interaction/.

Abstract: Virtual Reality (VR) and Augmented Reality (AR) head-mounted displays are increasingly being used in different computing related activities such as data visualization, education, and training. Currently, VR and AR devices lack efficient and ergonomic ways to perform common desktop interactions such as pointing-and-clicking and entering text. The goal of this project is to transform flat, everyday surfaces into a rich interactive surface. For example, a desk or a wall could be transformed into a virtual keyboard. Flat surfaces afford not only haptic feedback, but also provide ergonomic advantages by providing a place to rest your arms. This project will develop a system where microphones are placed on surfaces to enable the sensing of when and where a tap has occurred. Further, the system aims to differentiate different types of touch interactions such as tapping with a fingernail, tapping with a finger pad, or making short swipe gestures.

This project will investigate different machine learning algorithms for producing a continuous coordinate for taps on a surface along with associated error bars. Using the confidence of sensed taps, the project will investigate ways to intelligently inform aspects of the user interface, e.g. guiding the autocorrection algorithm of a virtual keyboard decoder. Initially, the project will investigate sensing via an array of surface-mounted microphones and design “surface algorithms” to determine and compare the location accuracy of the finger taps on the virtual keyboard. These algorithms will experiment with different models including existing time-of-flight model, a new model based on Gaussian Process Regression, and a baseline of classification using support vector machines. For all models, the project will investigate the impact of the amount of training data from other users, and varying the amount of adaptation data from the target user. The project will compare surface microphones with approaches utilizing cameras and wrist-based inertial sensors. The project will generate human-factors results on the accuracy, user preference, and ergonomics of interacting midair versus on a rigid surface. By examining different sensors, input surfaces, and interface designs, the project will map the design space for future AR and VR interactive systems. The project will disseminate software and data allowing others to outfit tables or walls with microphones to enable rich interactive experiences.

Dr. Theda Daniels-Race to Present Seminar September 9

Published September 4, 2019

By Karen Johnson

Dr. Theda Daniels-Race, the Michael B. Voorheis Distinguished Professor in the Division of Electrical & Computer Engineering at Louisiana State University, will present her seminar, “Deposition, Characterization, and Developments in Hybrid Electronic Materials for Next-Generation Nanoelectronics,” on Monday, September 9, at 3:00 pm in Room 6452 of the Dow Environmental Sciences and Engineering Building.

This seminar is presented by the Institute of Computing and Cybersystems and the Michigan Tech Visiting Professor Program, which is funded by a grant to the Michigan Tech Provost Office from the State of Michigan’s King-Chavez-Parks Initiative.

Dr. Daniels-Race also has a joint appointment to the Center for Computation and Technology at Louisiana State University. She is the founder of the Applied Hybrid Electronic Materials & Structures Laboratory as well as Director of the ECE Division’s Electronic Materials & Devices Laboratory. Her research has encompassed a range of studies upon electronic materials from the growth of compound semiconductors via molecular beam epitaxy (MBE), to investigations of electron transport in low-dimensional systems such as quantum wells, wires, and dots, to device design and fabrication. Her current work is in the area of hybrid electronic materials (HEMs) and involves studies of sample morphologies, nanoscale electronic behavior, and the design of apparatus for HEM deposition.

Dr. Daniels-Race received her degrees in Electrical Engineering from Rice, Stanford, and Cornell universities, for the B.S., M.S., and Ph.D., respectively. As an undergraduate, she received a GEM (Graduate Engineering Minorities) Fellowship for her future MS studies, and while working on her masters, she was selected to receive one of fewer than ten CRFP (Cooperative Research Fellowship Program) competitive fellowships awarded nationally that year by AT&T for her PhD. Throughout her academic training, Daniels-Race worked in industry with corporations such as Union Carbide, Exxon, General Electric, and AT&T Bell Laboratories. She began her academic career with the ECE Department at Duke University, where she built that institution’s first MBE laboratory and, over the next thirteen years, established a program in experimental compound semiconductor materials research. Daniels-Race was recruited to join the LSU faculty where she conducts research upon HEMs for use in next-generation nanoscale devices. To the community she has been an active member of several professional societies including the IEEE, the American Physical Society, the Materials Research Society, and the National Society of Black Physicists. She is an ELATES (Executive Leadership in Academic Technology, Engineering and Science) alumna and is a strong advocate for minorities and women in science and engineering.

Seminar Abstract: Ubiquitous dependence upon semiconductor-based technology has reached a critical turning point. In effect “small has hit the wall” (Moore’s Law) as advancements, in everything from cell phones to satellites, struggle to keep pace with demands for smaller, faster, and ever more affordable devices. Thus, researchers operating under the broadly defined umbrella of nanoelectronics inherently challenge traditional solid-state electronic design paradigms and fabrication practices. To this end, my research focuses upon that which I have dubbed HEMs or “hybrid electronic materials.” In this talk, I will present an overview of work in progress, conducted by both my graduate and undergraduate students, as part of the Applied Hybrid Electronic Materials & Structures (AHEMS) Laboratory that I have established in the Division of Electrical and Computer Engineering at Louisiana State University. With an eye toward the next generation of electronics, new materials and nanoscale structures must be investigated in order to understand the unique physics and potential applications of electronic phenomena “beyond the transistor.” Using hybrid (inorganic-organic) electronic materials, my group works to characterize the nanoscale formations and electronic behavior of HEMs, as well as to develop innovative yet low-cost apparatus and techniques through which these materials may be explored.

Soner Onder Presents Keynote at SAMOS XIX

Published August 14, 2019

By Karen Johnson

Soner Onder (SAS), professor of computer science, presented a keynote lecture July 8, 2019, at the International Conference on Embedded Computer Systems: Architectures, Modeling and Simulation (SAMOS XIX) on Samos Island, Greece, which was held July 7-11. Onder’s talk was titled, “Form Follows Function: The Case for Homogeneous Computer Architectures.” Onder also participated in the conference’s “The Annual Open Mike Panel.”

Keynote Lecture Abstract: ”Form follows function” is a principle associated with 20th-century modernist architecture and industrial design which says that the shape of a building or object should primarily relate to its intended function or purpose”[2]. For best performance in computer architecture, form must follow function as well. What are form and function in computer architecture? Form is easy to understand and interpret in its dictionary meaning; Function is not so clear-cut. In this talk, I will start with a simple problem, an algorithm, and a basic program representation that will be interpreted by the machine, and show that delivering high performance rests on solving only a handful, but fundamentally difficult problems. I will argue that the mere existence of domain specific solutions that general purpose computing cannot match in performance is a testament that the general purpose computing is ”not general enough”. What makes an architecture ”not general enough” is not the architecture itself, but rather the mismatch between the function its form had followed and the actual semantics of programs. To illustrate the point, I will challenge the widely understood interpretation of instruction-level parallelism (ILP) as ”single-thread performance”, and show that this interpretation is too short-sighted. We can efficiently exploit all types of available parallelism, including process-level, thread-level and data level parallelism, all at the instruction-level, and this approach is both feasible and necessary to combat the complexity that is plaguing our profession. I will then discuss why an executable single-assignment program representation [1] may be the ultimate function whose implementations may result in homogeneous general purpose architectures that can potentially match the performance of accelerators for specific tasks, while exceeding the performance of any accelerator traditional architecture combination for general tasks. I will conclude by discussing our results with Demand-driven Execution (DDE), whose form follows this single-assignment program representation.

About SAMOS (from http://samos-conference.com/): SAMOS is a unique conference. It deals with embedded systems (sort of) but that is not what makes it different. It brings together every year researchers from both academia and industry on the quiet and inspiring northern mountainside of the Mediterranean island of Samos, which in itself is different. But more importantly, it really fosters collaboration rather than competition. Formal and intensive technical sessions are only held in the mornings.A lively panel or distinguished keynote speaker ends the formal part of the day, and leads nicely into the afternoons and evenings — reserved for informal discussions, good food, and the inviting Aegean Sea. The conference papers will be published by Springer’s Lecture Notes in Computer Science – LNCS and will be included in the DBLP Database.

About the Workshop on Parallel-in-time Integration (from https://parallel-in-time.org/ and https://parallel-in-time.org/events/9th-pint-workshop/)

Computer models and simulations play a central role in the study of complex systems in engineering, life sciences, medicine, chemistry, and physics. Utilizing modern supercomputers to run models and simulations allows for experimentation in virtual laboratories, thus saving both time and resources. Although the next generation of supercomputers will contain an unprecedented number of processors, this will not automatically increase the speed of running simulations. New mathematical algorithms are needed that can fully harness the processing potential of these new systems. Parallel-in-time methods, the subject of this workshop, are timely and necessary, as they extend existing computer models to these next generation machines by adding a new dimension of scalability. Thus, the use of parallel-in-time methods will provide dramatically faster simulations in many important areas, such as biomedical applications (e.g., heart modeling), computational fluid dynamics (e.g., aerodynamics and weather prediction), and machine learning. Computational and applied mathematics plays a foundational role in this projected advancement.

The primary focus of the proposed parallel-in-time workshop is to disseminate cutting-edge research and facilitate scientific discussions on the field of parallel time integration methods. This workshop aligns with the National Strategic Computing Initiative (NCSI) objective: “increase coherence between technology for modeling/simulation and data analytics”. The need for parallel time integration is being driven by microprocessor trends, where future speedups for computational simulations will come through using increasing numbers of cores and not through faster clock speeds. Thus as spatial parallelism techniques saturate, parallelization in the time direction offers the best avenue for leveraging next generation supercomputers with billions of processors. Regarding the mathematical treatment of parallel time integrators, one must use advanced methodologies from the theory of partial differential equations in a functional analytic setting, numerical discretization and integration, convergence analyses of iterative methods, and the development and implementation of new parallel algorithms. Thus, the workshop will bring together an interdisciplinary group of experts spanning these areas.
