Privacy-Preserving Visual Recognition Framework for Surveillance
Abstract The widespread deployment of video surveillance systems has raised privacy awareness to the public. The main reason is that the facial attributes provide details about the identity of a subject and reveal other person-related information such as gender, race, and age. When humans are the dominant objects of interest in computer vision (CV) applications,
Applying Machine Learning to mitigate RF impairments in wireless communications systems
Abstract In traditional wireless communications systems, multiple complex digital signal processing blocks are designed to combat the imperfect radio frequency front-end components. However, due to Part-to-part, Voltage, and Temperature variation, an algorithm working well on one device may not work well on the others. Also, it is not efficient as each block needs to regularly
Designing 6G Wireless Communication Networks
Abstract In the current wireless communication system, propagation environment is randomly varying and independent to both base stations and user devices. There might be a period the propagation environment experiences a deep fading and thus the quality of service for one or multiple users is unacceptable. A promising technology for the sixth-generation wireless communication is
Vacuum Packaged Low-Power Resonant MEMS Strain Sensor
Abstract This paper describes a technical approach toward the realization of a low-power temperature- ompensated micromachined resonant strain sensor. The sensor design is based on two identical and orthogonally-oriented resonators where the differential frequency is utilized to provide an output proportional to the applied strain with temperature compensation achieved to first order. Interface circuits comprising
An Efficient QoE-Aware HTTP Adaptive Streaming over Software Defined Networking
Abstract Due to the increase in video streaming traffic over the Internet, more innovative methods are in demand for improving both Quality of Experience (QoE) of users and Quality of Service (QoS) of providers. In recent years, HTTP Adaptive Streaming (HAS) has received significant attention from both industry and academia based on its impacts on
Global Context Aware Convolutions for 3D Point Cloud Understanding
Abstract Recent advances in deep learning for 3D point clouds have shown great promises in scene understanding tasks thanks to the introduction of convolution operators to consume 3D point clouds directly in a neural network. Point cloud data, however, could have arbitrary rotations, especially those acquired from 3D scanning. Recent works show that it is
Post-COVID-1 9 Reflections Around the World: A New AJPH Forum
Abstract Emotions are key drivers of consumption in the tourism and hospitality sector. Therefore, advancing our understanding of the determinants of consumer emotions is critical for tourism and hospitality marketers to effectively influence consumer affect-driven consumption behavior. However, research on the determinants of pre-consumption emotions remains under-explored. This study aims to fill the research gap
Prioritizing Training Needs of School Health Staff: The Example of Vietnam
Abstract Competencies of school health staff (SHS) members, including school nurses, are crucial to improving child and adolescent health. In Vietnam, although SHS members are dispatched to schools, they have limited training opportunities. This study identified SHS members’ training needs in a province of Vietnam. A cross-sectional, online survey was conducted with 204 SHS members.
Differential Wound Healing Capacity of Mesenchymal Stem Cell-Derived Exosomes Originated From Bone Marrow, Adipose Tissue and Umbilical Cord Under Serum – and Xeno-Free Condition
Abstract Exosomes are nano-scale and closed membrane vesicles which are promising for therapeutic applications due to exosome-enclosed therapeutic molecules such as DNA, small RNAs, proteins and lipids. Recently, it has been demonstrated that mesenchymal stem cell (MSC)-derived exosomes have capacity to regulate many biological events associated with wound healing process, such as cell proliferation, cell
