Tacit Descriptions: Uncovering Ambiguity In Crowdsourced Descriptions Of Motions And Materials, Shreyosi Endow, Cesar Torres

Association of Computing Machinery Open Access Agreement Publications-Archive

Although a picture, GIF, or tutorial video is "worth a thousand words", every viewer has a unique perspective of which words they ‘see.’ Packed with rich meaning, these words, or descriptions, are often used to describe the ambiguity of working with materials, artifacts, and processes in creative practices. Our work reframes the traditional crowdsourced description tasks to leverage crowdworker diversity in generating a corpus of tacit descriptions. These descriptions are synthesized into a typology and describe how users communicate ambiguity and tacit knowledge embedded in unfamiliar material properties and familiar handed motions. We propose three design concepts that demonstrate how …

Thermoplastic Kilnforms: Extending Glass Kilnforming Techniques To Thermoplastic Materials Using Ontology-Driven Design, Mohammad Abu Nasir Rakib, Jeremy Scidmore, Justin Ginsberg, Cesar Torres

Association of Computing Machinery Open Access Agreement Publications-Archive

The ecology of thermoplastic materials is rapidly evolving, enabling an exciting landscape of functional, aesthetic, and interactive forms. Despite their utility in fused flament fabrication (FFF), an even larger and untapped design space exists for thermoplastics. In this work, we introduce a design method that leverages similarities with a more mature medium (glass) to guide a material-centered exploration of a new medium (thermoplastics). Through a collaboration between domain experts in thermoplastics and glass, we synthesized an ontology of kilnforming techniques and developed an annotated portfolio of thermoplastic kilnforms that capture generative design directions for altering the phenomenological qualities of plastic, …

Smartfunction: An Immersive Vr System To Assess Attention Using Embodied Cognition, Ashish Jaiswal, Aref Hebri, Pavel Hamza Reza, Zadeh Mohammad Zaki, Fillia Makedon

Association of Computing Machinery Open Access Agreement Publications-Archive

In traditional neuropsychological tests, executive functions (EFs) are typically evaluated using paper and pencil or computer-based sit-down tasks. However, a new assessment framework, the Automated Test of Embodied Cognition (ATEC), has been developed to measure EFs and embodied cognition through physical tasks. This paper proposes integrating the ATEC system with virtual reality (VR) to evaluate and diagnose attention-deficit disorders using embodied cognition (EC) principles. The VR system will utilize Meta Quest 2 VR headsets and controllers with motion sensors to accurately capture users’ physical movements. The collected motion data will be transmitted to a remote server for evaluation through machine …

Association of Computing Machinery Open Access Agreement Publications-Archive

We present a method for extracting high-level semantic information through successful landmark detection using feature fusion between RGB and depth information. We focus on the classification of specific labels (open path, humans, staircases, doorways, obstacles) in the encountered scene, which can be a fundamental source of information enhancing scene understanding, and acting towards the safe navigation of the mobile unit. Experiments are conducted using a manual wheelchair equipped with a stereo RGB-D camera that captures image instances consisting of multiple labels before fine-tuning on a pre-trained Vision Transformer (ViT).

A Teleoperation Framework For Robots Utilizing Control Barrier Functions In Virtual Reality, Aref Hebri, Sneh Acharya, Fillia Makedon

Association of Computing Machinery Open Access Agreement Publications-Archive

This paper describes a novel shared control teleoperation framework for mobile robots that utilizes Control Barrier Functions (CBFs) as filtering mechanism to prevent a human operator from making dangerous actions. The proposed framework demonstrates the potential to create a CBF controller that enables users with no prior knowledge of robotics to safely tele-navigate mobile robots with limited situational awareness. As formal methods, we utilize a hand-crafted CBF, which acts as a repulsive field to describe unsafe regions withing the robot’s vicinity. The implementation of the application was deemed possible by creating a Virtual Reality (VR) simulation in the Unity Engine …

Detecting Cognitive Fatigue In Subjects With Traumatic Brain Injury From Fmri Scans Using Self-Supervised Learning, Ashish Jaiswal, Ramesh Babu Ashwin, Zadeh Mohammad Zaki, Glenn Wylie, Fillia Makedon

Association of Computing Machinery Open Access Agreement Publications-Archive

Understanding cognitive states from fMRI data have yet to be investigated to its full extent due to its complex nature. In this work, the problem of understanding cognitive fatigue among TBI patients has been formulated as a multi-class classification problem. We built a Spatio-temporal encoder model using convolutions and LSTMs as the building blocks to extract spatial features and to model the 4D nature of fMRI scans. To learn a better representation of the data and the condition, we used a self-supervised learning technique called "Contrastive Learning" to pretrain our encoder with a public dataset BOLD5000 and further fine-tuned our …

Evaluation Of Video Compression Methods For Network Transmission On Diverse Data: A Case Study, Roman Strukov, Vassilis Athitsos

Association of Computing Machinery Open Access Agreement Publications-Archive

There is a variety of video compression methods proposed in the literature. Choosing the best method for a specific type of video can involve a lot of experimentation and trial-and-error. This paper offers a quantitative evaluation of three popular compression methods, namely HEVC, MJPEG, MJPEG2000. Our evaluation uses five different types of video data that are commonly transmitted over a network. We use two evaluation metrics, namely PSNR and encoding time. While our evaluation is still preliminary, and will eventually be expanded to include more compression methods, larger datasets, and more metrics, it already includes features not encountered in evaluations …

Turbohash: A Hash Table For Key-Value Store On Persistent Memory, Xingsheng Zhao, Chen Zhong, Song Jiang

Association of Computing Machinery Open Access Agreement Publications-Archive

Major efforts on the design of persistent hash table on a non-volatile byte-addressable memory focus on efficient support of crash consistency with fence/flush primitives as well on non-disruptive table rehashing operations. When a data entry in a hash bucket cannot be updated with one atomic write, out-of-place update, instead of in-place update, is required to avoid data corruption after a failure. This often causes extra fences/flushes. Meanwhile, when open addressing techniques, such as linear probing, are adopted for high load factor, the scope of search for a key can be large. Excessive use of fence/flush and extended key search paths …

Cogcues: Shifting Perception Through Interactive Projected Cues In Still Life Drawing, Bijisa Pyakurel, Shreyosi Endow, Carlos Donjuan, César Torres

Association of Computing Machinery Open Access Agreement Publications-Archive

The ability to visually discern shape, form, and value is fundamental to observational drawing. However, developing this skill requires a drawer to perceive a “raw” version of the scene being drawn, often referred to as regaining the innocence of the eye. This work investigates how interactive projected light cues can be used to alter the perception of drawing objects and understand how users might control their own perception. We introduce an augmented reality system capable of dynamically projecting interactive light cues onto objects within a live drawing studio. We present the design of three cues that address challenging percepts for …

Towards Robust Lidar-Based 3d Detection And Tracking Of Uavs, Tasnim Azad Abir, Endrowednes Kuantama, Richard Han, Judith Dawes, Rich Mildren, Phuc Nguyen

Association of Computing Machinery Open Access Agreement Publications-Archive

In this paper, we study the robustness of lidar-based 3D detection & tracking of UAVs. We investigate the effective detection ranges of different UAVs based on their construction materials and the effective range & 3D detection performance of a specific UAV at different atmospheric visibility conditions. Further, we examine to what extent lidar-based systems can track a drone's trajectories via real-world experiments and point cloud data processing. Using a COTS lidar-based system (Livox Mid-40), we confirm that we can track UAVs in a fine-grained manner at up to 80m distance under various environmental conditions (i.e., morning, afternoon, and night).

Dronechase: A Mobile And Automated Cross-Modality System For Continuous Drone Tracking, Neel R. Vora, Yi Wu, Jian Liu, Phuc Nguyen

Association of Computing Machinery Open Access Agreement Publications-Archive

This paper presents DroneChase, an automated sensing system that monitors acoustic and visual signals captured from a nearby flying drone to track its trajectory in both line-of-sight and non-line-of-sight conditions under mobility settings. Although drone monitoring has been an active research topic, most of the existing monitoring systems focus only on line-of-sight conditions and do not perform well under blockage conditions. Inspired by the human ability to localize objects in the environment using both visual and auditory signals, we develop a mobile system that integrates the information from multiple modalities into a reference scenario and performs real-time drone detection and …

Effects Of A Repeated Reading Intervention Delivered Online To Upper Elementary Students, John Elwood Romig, Ashley Jetton

SAGE Open Access Agreement Publications-Archive

Repeated reading is an intervention with strong evidence for improving students' oral reading fluency. However, little research has examined the use of this intervention outside of traditional school contexts. School closures due to COVID-19 forced schools and teacher preparation programs to create new approaches to evidence-based reading interventions that could be delivered online. This study examined the effects of a repeated reading fluency intervention delivered synchronously online. A single-case repeated acquisition design examined the intervention's effects on three upper elementary students' correct word reading fluency, defined as the number of words read correctly per minute. Visual analysis indicated repeated readings …

The Lived Experiences Of Faculty Conducting Post-Simulation Debriefing In Nurse Practitioner Programs, Jodi Borden Duncan

Doctoral Dissertations and Projects

Simulation-based education is a teaching–learning pedagogy widely used in nursing programs today. While much research has been done on student perceptions of simulation and the fact most learning occurs in the post-simulation debriefing session, little research has been done on how learning takes place in debriefing. Nurse practitioner faculty also use simulation as a teaching methodology, but the implementation of debriefing methods and faculty experiences with debriefing sessions are not known. As simulation may not be counted as direct clinical hours in nurse practitioner programs, more research must be done before the substitution of hours can be considered. The substitution …

Findings suggest a substantial reliance on motor vehicles and it was evident that many participants had never seriously considered what they would do if they …

Incorporating Job Competition And Matching To An Indicator-Based Transportation Equity Analysis For Auto And Transit In Dallas-Fort Worth Area, Seyedsoheil Sharifiasl, Subham Kharel, Qisheng Pan

SAGE Open Access Agreement Publications-Archive

Transportation equity is a vital but vague issue for planners and engineers in the United States, where mobility-based transportation planning has triggered the disproportionate distribution of benefits and burdens in the transportation system. Previously, transportation equity studies have evaluated equity using different transportation service metrics and socio-demographic factors. Job accessibility is one principal metric for transportation quality as it directly relates to a community's economic prosperity. While most equity studies analyze aggregate accessibility for a single mode, our study measures blue-collar and white-collar job accessibilities for automobile and transit by incorporating job proximity, competition, and matching, using the Dallas-Fort Worth …

Students were to complete their racism audit on their school campus. However, several students refused to complete the assignment. Some students refused for fear of job repercussions, while others accused Dr. Edwards of indoctrinating them with liberal political ideologies. This case explores the complexity and dilemmas that faculty encounter as they engage in antiracism leadership teaching during a time of racial …

Electrical Resistivity Imaging For Identifying Critical Sulfate Concentration Zones Along Highways, Mina Zamanian, Natnael Asfaw, Prakash Chavda, Mohsen Shahandashti

SAGE Open Access Agreement Publications-Archive

Assessing sulfate concentration levels and their distributions within road alignments is crucial for the design of highway projects. Sulfate minerals in soils react with calcium-based additives, leading to sulfate-induced heaving and pavement failures. However, a reasonable assessment of the extent and levels of sulfate concentration using current practices, such as conventional laboratory-based methods, is still challenging because of the spatial heterogeneity of sulfate minerals and their seasonal fluctuations. This study aims to assess the application of electrical resistivity imaging (ERI) to determine levels and distributions of sulfate concentration. Finite element and least-squares optimization were used to process the data and …

Reducing Officer-Involved Deaths Of Civilians In Urban Areas: Forecasting The Effects Of Departmental Policies, James D. Kelsay, Ian A. Silver, Leah C. Butler

SAGE Open Access Agreement Publications-Archive

Recent police-involved deaths of Black civilians have sparked public outcry and demand for police reforms. However, many departmental policies intended to reduce the lethal use-of-force by police officers lack empirical support for their effectiveness. To address this shortcoming, a Bayesian random intercept model is used to forecast the effects of eight departmental policies on the number of police-involved civilian deaths across 66 police departments. Results suggest that although several policies are associated with a reduction in officer-involved deaths of civilians in some police departments, they are unlikely to eliminate officer-involved deaths completely. Specifically, we observed that introducing additional departmental policies …
