Precisely classifying and tracking these species enriches our comprehension of their movement patterns and empowers us to create precise maps of species-specific territories. Such profound insights are pivotal in conserving endangered species, promoting sustainable fishing practices, and preserving marine ecosystems’ overall health and equilibrium. To partially address these needs, we present a proposed model that combines YOLOv8 for object detection with ByteTrack for tracking. YOLOv8’s oriented bounding boxes help to improve object detection across angles, while ByteTrack’s robustness in various scenarios makes it ideal for real-time tracking. Experimental results using the SEAMAPD21 dataset show the model’s effectiveness, with YOLOv8n being the lightweight yet modestly accurate option, suitable for constrained environments. The study also identifies challenges in fish tracking, such as lighting variations and fish appearance changes, and proposes solutions for future research. Overall, the proposed model shows promising fish tracking and counting results, which is essential for monitoring marine life.","PeriodicalId":178341,"journal":{"name":"Defense + Commercial Sensing","volume":"6 11","pages":"130610E - 130610E-7"},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141378676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While concerns about the threats of misinformation on the mental health of individuals have garnered attention, there remains a critical gap in our understanding of how misinformation uniquely affects the young generation, particularly those belonging to underrepresented groups. Emerging evidence suggests that underrepresented groups among the young generation, including marginalized communities, ethnic minorities, and socioeconomically disadvantaged individuals, often face heightened vulnerabilities to the harmful effects of misinformation. These groups encounter a unique intersection of social, economic, and cultural factors, exacerbating their susceptibility to false or harmful information. Understanding the differential impacts of misinformation within these communities is vital for creating targeted interventions and support mechanisms. With a long-term goal of offering a thorough understanding of the current state of knowledge in this critical area, this paper reports a preliminary literature review examining how false information about vaccines spreads on social media, creating a huge problem called an “infodemic” and revealing how misinformation against vaccines gets shared in social media and why people believe them. In addition, a small-scale case study is conducted based on the dataset collected by the team.","PeriodicalId":178341,"journal":{"name":"Defense + Commercial Sensing","volume":"14 20","pages":"130580Y - 130580Y-17"},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141380134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A strict, lifelong gluten-free diet is the only treatment. Currently, the most commonly used methods for gluten test are based upon enzyme-linked immunosorbent assay, which is sample-destructive, and requires cumbersome processing procedures, and therefore are not suitable for high-throughput real-time screening detection of gluten in foods. In this study, a Fourier-Transform Infrared (FT-IR) spectroscopy-based approach was proposed for authentication of gluten-free flour. Three chemical standards including gliadin, gluten, and starch from wheat and 62 different types of flour products were scanned by FT-IR spectroscopy over the wavenumber range of 4000 and 400 cm-1. Notable absorbance differences were observed between the chemical standards of gliadin and gluten and starch from wheat over the wavenumber range of 1800-450 cm-1. The mean absorbance profiles of gluten-free and non-gluten free categories of flour demonstrated varying spectral characteristics between 1800 and 1500 cm-1. The Principal Component Analysis (PCA)- Linear Discriminant Analysis (LDA) models built upon the original absorbance of flour between 1800 and 1500 cm-1 achieved overall prediction accuracies of at least 95.7%. The potential of FT-IR technique in identifying and authenticating gluten-free flour was demonstrated.","PeriodicalId":178341,"journal":{"name":"Defense + Commercial Sensing","volume":"105 3","pages":"1306009 - 1306009-6"},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141377918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the core of our methodology is the integration of Long Short-Term Memory (LSTM) networks with Proximal Policy Optimization (PPO) models, utilizing a deep reinforcement learning framework to interpret and predict user movement intentions in real time. By harnessing sensor fusion that combines surface electromyography (sEMG) and Inertial Measurement Units (IMU) from sensor arrays placed around the quadriceps and gastrocnemius muscles, our system employs an adaptive nonlinear sliding mode control with Pneumatic Artificial Muscles (PAMs), thereby directing the exoskeleton's movement and positioning. The LSTM network processes temporal sequences of sensor data to capture the dynamics of human motion, while the PPO model optimizes the control policy to ensure smooth and responsive movements aligned with the user intentions. Focusing initially on basic maneuvers integral to Activities of Daily Living (ADL), our system demonstrates promising preliminary results in mimicking natural limb movements, laying the groundwork for future clinical applications. This paper specifically delves into the utilization of the LSTM-PPO framework for controlling an avatar prior to testing the exoskeleton, representing a significant step towards realizing a responsive and intuitive exoskeleton control system.","PeriodicalId":178341,"journal":{"name":"Defense + Commercial Sensing","volume":"3 7","pages":"1305805 - 1305805-9"},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141380429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have been developing SPD technology previously reported at DCS2022 but recently achieved detection and recording of photoelectron (PE) pulse width ⪅500ps with 1Gcps saturation count with near 7LOG Dynamic Range (DR). The current challenge involves developing a spectral photon detection system that works in the range from ultraviolet to near infrared region. We have developed a six-decade dynamic range spectrometer from 360nm to 820nm, with a 42 channels fiber array (42CH) that distributes each spectral window onto an individual pixel-coupled silicon photomultiplier (SiPM), each channel has a 10.9nm bandwidth. The detected PE streams of the 42CH are captured with an FPGA at 10Gs/s with 100ps time resolution using multi-GHz electronics and thermoelectric cooling, and produce a huge data stream of 420Gs/s. We have identified interference problems on the system which arise from using conventional packaging with gold wire connection in dry nitrogen such as oscillation, crosstalk between adjacent channels and interference from external radiation such as Wi-Fi and cellular RF signals. To resolve electrical interference and improve signal quality, the sensor chips were mounted on an eight-layer Chip-On-Board (COB). Improving the sensor environment was the other focus for our system. We have designed a two stagesthermoelectric device targeted at -30°C with a moisture getter in the sensor package to reduce the thermal electron and the dark count of the SiPM. This design is an innovative approach in the packaging method that helps to control the environment inside the sensor. Earlier photon spectroscopy required a considerable time to scan a full spectral range using a monochromator. Our newly developed 42CH multiwavelength spectrometer allows the capture of a spectral fingerprint in microseconds to microseconds with potential readout in SI units. The system under development will contribute various applications in the fast-developing quantum field.","PeriodicalId":178341,"journal":{"name":"Defense + Commercial Sensing","volume":"58 4","pages":"1305902 - 1305902-9"},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141376365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gadsden","doi":"10.1117/12.3013732","DOIUrl":"https://doi.org/10.1117/12.3013732","url":null,"abstract":"Deployed for purposes of GPS, defense, atmospheric and space research, environmental monitoring, broadcasting, and communication, Earth observation satellites are complex systems that require the design of highly reliable control and estimation algorithms. A satellite’s Attitude Determination and Control System (ADCS) must be able to operate accurately, in a robust manner against unexpected conditions, especially in missions that demand more intricate tasks. The desire for optimal and robust performance in satellites has been the driving factor behind decades of attitude control research. With computers, the performance of spacecraft subject to some mission can be simulated to test new control methods, but the availability of real satellites to researchers for testing these algorithms is very limited. To solve this issue, attitude control simulators have been developed, such that algorithms and hardware can be tested inexpensively in a lab environment, while maintaining a high level of accuracy to the environment it emulates. The Nanosatellite Attitude Control Simulator (NACS) has been developed at McMaster University for this purpose. Consisting of a mock 1U CubeSat, an air-bearing configuration, and an Automatic Balancing System (ABS), rotational attitude control experiments are conducted in-lab without deployment, simulating the zero-gravity of space. The mechanism responsible for environment simulation is the ABS, which minimizes residual torque due to gravity by influencing the center of mass (CoM) of the system, thereby improving control performance and efficiency. The performance of the ABS in a balancing task is presented, where system parameters of inertia and CoM are estimated from response data. Three filtering strategies are investigated for this purpose, providing varying degrees of accuracy and computational cost.","PeriodicalId":178341,"journal":{"name":"Defense + Commercial Sensing","volume":"84 s373","pages":"130620M - 130620M-19"},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141376330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
