Runtime Detection Of A Bandwidth Denial Attack From A Rogue Network-On-Chip, Rajesh Jayashankarashridevi, Dean Michael Ancajas, Koushik Chakraborty, Sanghamitra Roy

Electrical and Computer Engineering Faculty Publications

In this paper, we propose a covert threat model for MPSoCs designed using 3rd party Network-on-Chips (NoC). We illustrate that a malicious NoC can disrupt the availability of on-chip resources, thereby causing large performance bottlenecks for the software running on the MPSoC platform. We then propose a runtime latency auditor that enables an MPSoC integrator to monitor the trustworthiness of the deployed NoC throughout the chip lifetime. For the proposed technique, our comprehensive cross-layer analysis indicates modest overheads of 12.73% in area, 9.844% in power and 5.4% in terms of network latency.

Modifying The Adm1 Model To Predict The Operation Of An Anaerobic Digester Co-Digesting Municipal Sludge With Bakery Waste, Morris E. Demitry, Jianming Zhong, Conly Hansen, Michael Mcfarland

Civil and Environmental Engineering Faculty Publications

Anaerobic Digestion Model Number1 (ADM1) was modified in order to predict accurately the impact of co-digesting bakery waste (BW) with municipal sludge (MS). BW is an industrial waste (300,000 gallons per day in USA) that contains a high concentration of organic matter (carbohydrates, low lipids and non-detected proteins). BW is an easily biodegradable substrate for creating a favorable microorganism growth environment, which enhances the biogas production needed for wastewater facilities. The modified ADM1 successfully predicted changes in pH, volatile fatty acids (VFA), propionic acid and methane gas production. The ADM1 outputs were compared to experimental batch reactor results of actual …

Thermal Earth Resource Monitoring Instrument (Thermi) Size, Weight And Power (Swap) Reduction, T. Newswander, Z. Bergen, J. Hancock, S. Hansen, A. Shumway, J. Stauder, D. Williams

Space Dynamics Laboratory Publications

The Thermal Earth Resource Monitoring Instrument (THERMI) has been designed to meet stringent Landsat heritage requirements with reduced size, weight and power (SWaP). The instrument design provides Earth resource monitoring through the use of two long-wave infrared bands that measure the land surface temperatures. These bands are especially valuable for monitoring water resources and water use. Instrument subsystems, including electronics, cryocooler, thermal management, optical telescope assembly, focal plane module, in-flight calibrator, and scene select mirror were studied and conceptually designed to reduce overall THERMI SWaP. Reductions in SWaP make it possible for THERMI to fit on a small satellite bus …

Phase Change Cells And The Verification Of Gallium As A Thermal Calibration Reference In Space, Harri Latvikoski, Gail E. Bingham, T. Shane Topham, Igor Podolski

Space Dynamics Laboratory Publications

The validation of models of global climate change and accurate measurement of the atmosphere and surface temperatures require that orbital sensors have low drift rates, and are monitored or regularly recalibrated by accepted standards. Phase change materials (PCM), such as those that make up the ITS-90 standard, are the basis for international commerce and have been suggested for monitoring and recalibration of orbital temperature sensors. Space Dynamics Laboratory (SDL) and its partners have been developing miniaturized phase change reference technologies that could be deployed on an orbital blackbody for nearly a decade. A significant part of this effort has been …

Contributions Of Mass And Bond Energy Difference And Interface Defects On Thermal Boundary Conductance, Nicholas A. Roberts, Changjin Choi

Mechanical and Aerospace Engineering Faculty Publications

The impact of mass and bond energy difference and interface defects on thermal boundary conductance (TBC) is investigated using non-equilibrium molecular dynamics (NEMD) with the Lennard-Jones (L-J) interatomic potential. Results show that the maximum TBC is achieved when the mass and bond energy of two dissimilar materials are matched, although the effective thermal conductivity is not necessarily a maximum due to the contributions of the thermal conductivity of the constituent materials. Mass and bond energy differences result in a mismatch between phonon dispersions, limiting high frequency phonon transport at the interface. This frequency mismatch is defined by a frequency ratio, …

Agricultural Water Management In The Sevier River Basin, Utah: A Multidisciplinary Approach, Daeha Kim

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Sevier River Basin situated in south central Utah is characterized by its semiarid climate, snowmelt-driven runoff, and high dependency on agricultural economy. High evapotranspiration and low precipitation make agricultural production challenging, but naturally stored water in the snowpack in the mountains alleviates water stresses during high water demand seasons. The snowmelt-driven river flow along the main channel is highly exploited for irrigation for farms near the Sevier River. Reservoir operations and river diversions result in heavily regulated flows from the upper to the lower basins. The return flows of over-irrigated water in the upper basin increase salinity of surface …

Attacker-Induced Traffic Flow Instability In A Stream Of Automated Vehicles, Daniel D. Dunn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Highway systems world wide continue to see an ever increased number of vehicles and subsequently a rise in congested traffic. This results in longer commute times, wasted energy as vehicles idle in stop and go traffic, and increases the risk of accidents. In short, increased congestion costs time and money. These issues have prompted much research into Automated Highway Systems (AHS). In AHS vehicles using computer algorithms can safely travel at much smaller inter-vehicle distances than human drivers are capable of. This increases the capacity of existing highway systems. Sensors aboard each vehicle make this possible by monitoring their surroundings. …

Tackling Voltage Emergencies In Noc Through Timing Error Resilience., Rajesh Jayashankarashridevi, Dean Michael Ancajas, Koushik Chakraborty, Sanghamitra Roy

Electrical and Computer Engineering Faculty Publications

Aggressive technology scaling exacerbates the problem of voltage emergencies in emerging MPSoC systems. Network-on-Chips, the de-facto standard for connecting on-chip components in forthcoming devices play a central role in providing robust and reliable communication. In this work, we propose DrNoC (droop resilient network-on-chip)-two microarchitectural techniques to mitigate voltage emergency-induced timing errors in NoCs and preserve error-free communication throughout the network. DrNoC employs frequency downscaling and a pipeline error-recovery mechanism to reclaim corrupted flits in the router. Compared to the recently proposed NSFTR fault-tolerant technique, DrNoC offers a 27% improvement in energy-delay efficiency.

Interdisciplinary Modeling For Water-Related Issues Graduate Course, Laurel Saito, Alexander Fernald, Timothy Link

All ECSTATIC Materials

The science and management of aquatic ecosystems is inherently interdisciplinary, with issues associated with hydrology, atmospheric science, water quality, geochemistry, sociology, economics, environmental science, and ecology. Addressing water resources issues in any one discipline invariably involves effects that concern other disciplines, and attempts to address one issue often have consequences that exacerbate existing issues or concerns, or create new ones (Jørgensen et al. 1992; Lackey et al. 1975; Straskraba 1994) due to the strongly interactive nature of key processes (Christensen et al. 1996). Thus, research and management of aquatic ecosystems must be interdisciplinary to be most effective, but such truly …

Development Of A Decision-Making Methodology To Design A Water Quality Monitoring Network, J. Keum, Jagath J. Kaluarachchi

Civil and Environmental Engineering Faculty Publications

The number of water quality monitoring stations in the USA has decreased over the past few decades. Scarcity of observations can easily produce prediction uncertainty due to unreliable model calibration. An effective water quality monitoring network is important not only for model calibration and water quality prediction but also for resources management. Redundant or improperly located monitoring stations may cause increased monitoring costs without improvement to the understanding of water quality in watersheds. In this work, a decision-making methodology is proposed to design a water quality monitoring network by providing an adequate number of monitoring stations and their approximate locations …

Are We Preparing The Next Generation? K-12 Teacher Knowledge And Engagement In Teaching Core Stem Practices, Louis S. Nadelson, Anne Seifert, J. Kade Hendricks

Teacher Education and Leadership Faculty Publications

Background: Several of the recent reform efforts in K-12 STEM education (e.g. Next Generation Science Standards [NGSS and Common Core State Standards-Mathematics [CCSS-M]) have included significant emphasis on the practices of STEM. We argue that K-12 teachers' ability to effectively engage their students in these core STEM practices is fundamental to the success of potential and current engineering students and their subsequent careers as engineers. Practices such as identifying problems, modeling using mathematics, and arguing from evidence are fundamental processes in engineering. Helping students develop their capacity to engage in these practices early in their education will increase the likelihood …
