Computer Science and Computer Engineering Faculty Publications and Presentations

The common modeling of digital twins uses an information model to describe the physical machines. The integration of digital twins into productive cyber-physical cloud manufacturing (CPCM) systems imposes strong demands such as reducing overhead and saving resources. In this paper, we develop and investigate a new method for building cloud-based digital twins (CBDT), which can be adapted to the CPCM platform. Our method helps reduce computing resources in the information processing center for efficient interactions between human users and physical machines. We introduce a knowledge resource center (KRC) built on a cloud server for information intensive applications. An information model …

Microdisk Resonator With Negative Thermal Optical Coefficient Polymer For Refractive Index Sensing With Thermal Stability, Tao Ma, Jinhui Yuan, Feng Li, Lei Sun, Zhe Kang, Binbin Yan, Qiang Wu, Xinzhu Sang, Heng Liu, Fang Wang, Bo Wu, Chongxiu Yu, Gerald Farrell

Articles

In this paper, we propose a microdisk resonator with negative thermal optical coefficient (TOC) polymer for refractive index (RI) sensing with thermal stability. The transmission characteristics and sensing performances by using quasi-TE01 and quasi-TM01 modes are simulated by a three-dimensional finite element method. The influences of the TOC, RI, and thickness of the polymer on the sensing performances are also investigated. The simulation results show that the RI sensitivity Sn and temperature sensitivity ST with different polymers are in the ranges of 25.1-26 nm/RIU and 67.3-75.2 pm/K for the quasi-TE01 mode, and 94.5-110.6 nm/RIU and 1.2-51.3 pm/K for the quasi-TM01 …

Faculty & Staff Scholarship

A comprehensive monitoring program was conducted to measure the rock mass displacements, support response, and stress changes at a longwall tailgate entry in West Virginia. Monitoring was initiated a few days after development of the gateroad entries and continued during passage of the longwall panels on both sides of the entry. Monitoring included overcore stress measurements of the initial stress within the rock mass, changes in cable bolt loading, standing support pressure, roof deformation, rib deformation, stress changes in the coal pillar, and changes in the full three-dimensional stress tensor within the rock mass at six locations around the monitoring …

Deep Cover Bleeder Entry Performance And Support Loading: A Case Study, Ted M. Klemetti, Mark Alexander Van Dyke, Ihsan Berk Tulu

Faculty & Staff Scholarship

Several questions have emerged in relation to deep cover bleeder entry performance and support loading: how well do current modeling procedures calculate the rear abutment extent and loading? Does an improved understanding of the rear abutment extent warrant a change in standing support in bleeder entries? To help answer these questions and to determine the current utilization of standing support in bleeder entries, four bleeder entries at varying distances from the startup room were instrumented, observed, and numerically modeled. This paper details observations made by NIOSH researchers in the bleeder entries of a deep cover longwall panel—specifically data collected from …

Synthesis Of Volatile And Thermally Stable Aluminum Hydride Complexes And Their Use In Atomic Layer Deposition Of Metal Thin Films, Kyle Blakeney

Boundary Effects On The Locomotion Of Active Janus Particles, Marola W. Issa, Nicky R. Baumgartner

Undergraduate Research Posters 2018

Self-propelled or “active” micrometer scale particles are capable of supplying local mechanical work, necessary for microscale cargo delivery and useful in other applications within bioimaging and sensing. Research in the last decade has focused on developing, measuring, and manipulating the locomotion mechanisms of active particles in simple environments. However, many applications will be in complex environments with nearby boundaries or variations in physiochemical cues. This poster reports the directed motion of platinum coated polystyrene particles at infinite dilution in the presence of H2O2, which acts as a fuel to drive motion. A transport mechanism called “diffusiophoresis” drives motion of the …

Cardiovascular Biomechanical Models, Ethan Kung

Publications

Computational and in vitro methods offer powerful means to model the cardiovascular system and investigate biomechanics related to blood flow, cardiovascular tissue, and medical devices. These models can be constructed to directly describe human anatomy and physiology, and can be more highly controlled compared to animal models. Low-order models composed of lumped-parameter elements and simplified descriptions of cardiac function can capture the global physiology, while high-order models exhibiting detailed 3D anatomy and dynamics can provide highly realistic replication of biomechanical interactions in a small region of the circulation. Multiscale models offer the freedom to capture biomechanics in different regions at …

Dynamic Choke Sensing For Timing Error Resilience In Ntc Systems, Aatreyi Bal, Shamik Saha, Sanghamitra Roy, Koushik Chakraborty

Electrical and Computer Engineering Faculty Publications

Process variation (PV) is a conspicuous predicament for submicrometer VLSI circuits. In this paper, we illustrate "choke points" as a vital consequence of PV in the near-threshold computing domain. Choke points are PV affected sensitized logic gates with increased delay deviation. They dominate the choice of critical paths postfabrication. To mitigate the timing errors induced thereby, we propose dynamic choke sensing (DCS). This technique senses the timing error causing opcode sequences, and uses the knowledge to prevent similar sequences from causing errors in the future. We propose two variants of our scheme. Our techniques provide ~55% improvement in performance and …

Milwaukee Wet Weather Flow Management System Planning, David Watkins

All ECSTATIC Materials

Many older cities across the United States rely on combined sewers to convey both stormwater runoff and sanitary sewage. Combined sewer overflows (CSOs), containing untreated sewage, occur during extreme wet weather, when the capacity of these combined sewer systems is exceeded. Across the U.S., CSOs pose a serious threat to water quality in thousands of lake, river, and coastal ecosystems. In addition to harming the natural environment, they may be a threat to human health and have adverse economic consequences (e.g., beach closings, reduced aesthetics, tourism impacts).

In this assignment, students role-play engineering consultants tasked with developing a cost-effective plan …

Creating A Consistent Oceanic Multi-Decadal Intercalibrated Tmi-Gmi Constellation Data Record, Ruiyao Chen

Electronic Theses and Dissertations

The Tropical Rainfall Measuring Mission (TRMM), launched in late November 1997 into a low earth orbit, produced the longest microwave radiometric data time series of 17-plus years from the TRMM Microwave Imager (TMI). The Global Precipitation Measuring (GPM) mission is the follow-on to TRMM, designed to provide data continuity and advance precipitation measurement capabilities. The GPM Microwave Imager (GMI) performs as a brightness temperature (Tb) calibration standard for the intersatellite radiometric calibration (XCAL) for the other constellation members; and before GPM was launched, TMI was the XCAL standard. This dissertation aims at creating a consistent oceanic multi-decadal Tb data record …

Structured Light-Field Focusing 3d Density Measurements Of A Supersonic Cone, Ryonosuke Ozawa
