As the pandemic Covid-19 erupted worldwide in 2020, the entire world rapidly adopted online education as a means of sustaining the education system in universities and schools. However, the majority of students were unfamiliar with these methods, as they were accustomed to traditional classrooms. Some students may prefer online education over traditional education, but online education stress remains a persistent issue. This study investigated the stress encountered by students during online learning sessions. 220 university students participated in this quantitative correlational study. On the basis of 11 items developed and tested using Confirmatory Factor Analysis, a questionnaire consisting of three constructs of online learning stress, financial capacity, and positive perception of online learning was developed and administered. The data were subsequently evaluated using the Structural Model in order to comprehend the relationships between the variables. The model was discovered to have a high level of fitness and validity. Positive perceptions of online learning were discovered to predict student stress negatively. The financial capacity of students to purchase the necessary devices for online learning sessions had no effect on their stress levels. However, financial capacity is the antecedent of how positively students viewed online learning for themselves. This suggests that for online education to be successful, it is crucial to consider the students' perceptions by evaluating their access to all the devices and technologies associated with online learning.

The transition from in-person to online classes, accelerated by the global impact of Covid-19, has brought both accessibility and disengagement challenges. While online platforms facilitate learning for distant and international students, the loss of interactive elements diminishes the overall educational experience. This article proposes a novel solution inspired by MIT Professor Dr. Patrick Winston's concept of using “props” to enhance learning. Leveraging augmented reality (AR) technology, an application can be developed to introduce tangible AR elements into the online learning environment. The design and methodology outline the use of Python libraries, including OpenCV and Mediapipe, along with the Intel RealSense D435 depth camera. By employing hand-tracking techniques, real-world coordinates are deduced, allowing the creation of interactive AR objects. Trigonometry is utilized to convert 3D coordinates into 2D projections on the video screen, ensuring accurate representation. The visual perception of depth is achieved by subdividing lines, allowing for the dynamic interaction of virtual objects and real hands. The results and analysis section showcases the functionality of the developed application. A 3D cube or prism appears on-screen, responding to touch and rotation gestures. The collision detection algorithm, assuming a spherical bounding box, determines whether the cube is touched, altering its color and position accordingly. Limitations, such as the imprecise collision area for elongated shapes and potential aliasing issues, are discussed as sources of error. Looking forward, the discussion section explores future enhancements and applications. Incorporating advanced modeling tools like OpenGL or Wavefront could introduce more complex 3D models. Interactive features such as hand gestures for rotation or grabbing could further enrich the online learning experience. This project serves as a foundation for the development of interactive and engaging online

The U.S. Coast Guard is in the concept exploration phase of its Integrated Deepwater System (IDS) acquisition project. This project will define the next generation of surface, air and command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR) assets used to perform the Coast Guard's missions in the IDS environment (>50 NM off the U. S. coastline). As part of early technology investigations, the needs exist to: (1) analyze the workload requirements of the IDS, (2) identify alternative means to perform ship's work, and (3) optimize ship manning consistent with ship workload, performance criteria, and the available tools and equipment aboard. To reduce shipboard work requires an understanding of the mission and support requirements placed on the vessel and crew, how these requirements are currently met, and how requirements might otherwise be met to reduce workload and crew size. This study examined currently implemented workload and manpower reducing approaches of commercial maritime fleets, U.S. and foreign navies, and foreign coastguards. These approaches were analyzed according to evaluation criteria approved by the IDS acquisition project team. From this, strategies for shipboard work reduction that may be considered for adoption by the IDS were identified and analyzed according to performance and costs factors. Ten workload-reducing strategies were identified: damage control, bridge, multiple crewing, engineering, risk acceptance, modularity, deck, enabling technologies, ship/personnel readiness, and operability and maintainability.

Sustainable energy of Natural Gas (NG) has been an increasingly valuable and advantageous fossil fuel as it produces a cleaner combustion, and efficient consumption. Compressed Natural Gas (CNG) storage method and its utilisation has caused several problems due to high cost of installation for extensive 25.86 MPa highpressure bulky cylinder, internal cylinder corrosion, and the possibility of releasing an explosive compressed gas. Adsorb Natural Gas (ANG) storage as a new technology, where natural gas is adsorbed in a suitable adsorbent with high porosity to increase the volume of gas stored in the vessel at lower pressure 3.45 - 5.52 MPa is a promising alternative. The energy density stored in ANG storage system is greater than the CNG vessel at the same pressure. Solid sustainable material of Palm Kernel Shell (PKS) was treated chemically to obtain adsorbent media to determine its adsorption and desorption rate performance at certain pressure. The adsorbent obtained by treatment with KOH and H3PO4 labelled as PKS-ACB and PKS-ACA. Samples were characterised by SEM, BET, TGA and FTIR. The SEM, BET, TGA and FTIR results showed promising results. The adsorption rate of the first 20 minutes was 0.038 mmol/*** for PKS-ACA and 0.034 mmol/*** for PKSACB. The desorption rate of PKS-ACA and PKS-ACB was 643 mmol/*** and 430 mmol/***. There was no gas residual left in the sorbent. Findings highlighted that sustainable solid waste materials of palm kernel shell are renewable;its surface property as natural gas adsorbent storage known as ANG.

Due to the widespread nature of sun-related health risks, sophisticated UV monitoring systems are urgently needed. This research study introduces a cloud-based UV monitoring system with the intent of remotely tracking and analyzing UV exposure in real time. The system incorporates a network of UV sensors deployed in various locations, continuously collecting UV radiation data. These sensors are linked to a cloud system, which allows for easy sharing and processing of collected data. As a result, we're working to perfect a cutting-edge device that can monitor vitamin D absorption, measure cumulative UV exposure, and warn of impending danger. Extensive studies have demonstrated the benefits of UV exposure for both general health and protection against the newly discovered coronavirus. However, finding a happy medium is important because too much sun exposure can cause cancer, lupus flares, and cataracts. The proposed model gives users the ability to set their own daily UV exposure limits, taking into account clinically validated thresholds for various skin tones. The developed sensor module is able to measure the UV index with high precision even in bright sunlight because it closely mimics the skin erythema spectrum.

Space weathering is an important surface process occurring on the Moon and other airless bodies, especially those that have no magnetic field. The optical effects of the Moon’s space weathering have been largely investigated in the laboratory for lunar samples and lunar analogues. However, duplication of the pristine regolith on Earth is not possible. Here we report the space weathering from the unique perspective of the Chang′E-3′s (CE-3) "Yutu" rover, building on our previous work (Wang et al. 2017;Wu and Hapke 2018). Measurement of the visually undisturbed uppermost regolith as well as locations that have been affected by rocket exhaust from the spacecraft by the Visible-Near Infrared Spectrometer (VNIS) revealed that the returned samples bring a biased information about the pristine lunar regolith. The uppermost surficial regolith is much more weathered than the regolith immediately below, and the finest fraction is rich in space weathered products. These materials are very dark and attenuated throughout the visible and near-infrared (VNIR) wavelengths, hence reduce the reflectance and mask the absorption features. The effects on the spectral slope caused by space weathering are wavelength-dependent: the visible and near-infrared continuum slope (VNCS) increases while the visible slope (VS) decreases. In the visible wavelength, the optical effects of space weathering and TiO2 are identical: both reduce albedo and blue the spectra. This suggests that developing new TiO2 abundance algorithm is needed. Optical maturity indices are composition related and hence only locally meaningful. Since optical remote sensing can only sense the uppermost few microns of regolith and since this surface tends to be very weathered, the interpretation of surface composition using optical remote sensing data needs to be carefully evaluated. Sampling the uppermost surface is suggested. Copyright © 2018, The Authors. All rights reserved.

The mineralogy of mare basalts reflects the chemical composition of the magma source, as well as the physical and chemical environment of the rock's formation. It is significant for understanding the thermal evolution of the Moon. In this study, the spatial distribution of the mineralogy of the lunar northern nearside basalts was mapped using the Moon Mineralogy Mapper (M3) data. The study area, which is an elongated mare, Mare Frigoris and northern Mare Imbrium, was mapped and characterized into 27 units based on multi-source data, including spectrum, terrain, and element abundance. We extracted 177 M3 spectra from fresh craters. Spectral parameters such as absorption center and band area ratio (BAR) were obtained through data processing. The variation of mafic mineral of this region was acquired by analyzing these parameters. The basaltic units in eastern Mare Frigoris, which are older, have been found to be dominated by clinopyroxene with lower CaO compared to the returned lunar samples;this is similar to older basaltic units in Mare Imbrium. The basaltic units of western Mare Frigoris and Sinus Roris which are younger have been found to be rich in olivine. The late-stage basalts in Oceanus Procellarum and Mare Imbrium show the same feature. These wide-spread olivine-rich basalts suggest the uniqueness in the evolution of the Moon. Geographically speaking, Mare Frigoris is an individual mare, but the magma source region have connections with surrounding maria in consideration of mineral differences between western and eastern Frigoris, as well as mineral similarities with maria at the same location.97M50 (Primary), 85-03 (Secondary) Copyright © 2018, The Authors.
