In the IoT era, mobile sensors may be used to supervise inhabitants' health and publish acquired health data to cloud servers for communication, encouraging the creation of e-healthcare record (e-hcr) systems. Mobile cloud computing combines the features and advantages of mobile and cloud computing while overcoming this. However, before it can be extensively utilised, e-hcr systems must solve issues about privacy and efficiency. One of the most important aspects is the confidentiality of e- hcr's. Another challenge with mobile cloud computing is that wearable devices are typically resource constrained. The goal of this article is to discuss networked healthcare can help with application. Furthermore, if e-hcr data access laws are known, the online phase may create the final cypher messages fast. Proposed e-hcr access control framework supports access rules specified systems. © 2023 IEEE.

In designing a power system, efficacious synchronization of directional over-current relays (DOCRs) plays a pivotal role in guaranteeing the system's stability and ensuring continuous power flow, even in the event of disturbance. However, attaining this optimized strategy pertains to the persistence of solving extremely constrained and nonlinear optimized complications. The main intention is to formulate an optimized coordination strategy to optimize the overall operational time (OT) of DOCRs. This involves featuring optimized values of decision variables, specifically the relay plug settings (PS) and time dial settings (TDS). The designed formulation for DOCRs is employed on various IEEE bus networks like the 8, 9, and 15 bus systems. Comparative evaluation of obtained results is accomplished with numerous algorithms that showcase the competency of the GAMS-driven optimization strategy. The results depict that there is an improvement of 1.8-23 % in the total operational time of relays depending upon the test system under consideration. © 2024 IEEE.

Cobalt ferrite (CoFe2O4) based catalysts are known to have the excellent catalytic traits due to their usefulness as a photocatalyst and electrocatalyst for the hydrolysis of water in the field of sustainable growth. This research work is reported to understand the impact of calcination temperature on the photo and electro catalytic nature of CoFe2O4 ferrites for the green H2 generation. The CoFe2O4 ferrite has been fabricated using the sol-gel auto-combustion (SG) approach at different calcination temperatures (650°C, 750°C). According to the Rietveld refined XRD data, all samples showed the formation of Fd3m geometry representing the spinel phase with crystallite size increasing from 30.65 to 46.01 nm. The morphological studies revealed the existence of aggregates. The size of the aggregates with spherical morphology changes with the calcination temperature going from 46.78 nm to 92.55 nm. The VSM analysis indicates the ferromagnetic behavior of fabricated cobalt ferrites with the rise in saturation magnetization. The optical band analysis showed systematic band reduction to 1.45 eV from 1.72 eV. Moreover, it was observed that the inclining temperature causes increase in the inverse type of the cobalt ferrite, which benefits the catalytic processes. The water splitting studies demonstrated that the samples calcined at 750°C have high catalytic activity for both photo and electrocatalysis processes. The highest achieved H2 yield is of 27.99 mmol gcat−1 in 8 hours by the CF3 sample with the lowermost achieved Tafel slope of 106.22 mV/dec. Therefore, the current work shows that the cobalt ferrites have un-tapped potential in the field of H2 energy production. © 2025 Hydrogen Energy Publications LLC

The need for software improvement is growing widely due to the demand for technology development. The issues that arise by expanding the software processes in the workplace are expense, lack of understanding, time constrained, and lack user experience. This research paper focuses on proposing a framework for integrating design thinking into software process improvement. The secret to project success may lie in fusing methodological and reusable approaches with human-centric techniques. A mixed-methods research strategy is proposed to compile thorough information and reach conclusions. In addition, it incorporates components of both qualitative and quantitative research (secondary research and descriptive analysis). The assumption is that the existing model significantly affects the user satisfaction variable. This indicates a statistically significant association between the individual's experience (number of years) and design thinking integration into the software process improvement. The variables in the proposed model and the dependent variable user satisfaction accounts for 6.1 © 2024 IEEE.

Natural fibers are being explored nowadays to provide tensile strength needed in cementitious matrices. To give better bondage between the fibers and the matrices, surface enhancements for natural fibers can be induced through chemical treatments. In the current study, fibers are extracted from Bambusa Blumeana, an abundant local species of bamboo plant from the Philippines. Bamboo slats are pre-treated with varying concentration of 5%, 10% and 15% sodium hydroxide (NaOH) and extracted fibers are treated with 10% aluminium sulfate (Al2(SO4)3) solution. Extracted bamboo fibers are subjected to Single Strand Tensile test. It is observed that bamboo slats submerged in 5% NaOH provides better mean tensile peak load. Scanning Electron Microscopy (SEM) images shows however that the fibers submerged in higher concentrations has developed rougher surface enhancements. The results can be used for developing bamboo fiber reinforced fly-ash based geopolymer composites and with further studies, can be applied as textile reinforcement for structural strengthening or retrofitting. © 2022 IABSE Symposium Prague, 2022: Challenges for Existing and Oncoming Structures - Report.

Dynamic Characteristics of Rolling Agricultural Tire

engineering in Agriculture, Environment and Food 2021年第1期14卷 1-12页

作者： Fujita, Katsuhide Saito, Takashi Kaneko, Mitsugu Department of Mechanical Engineering National Institute of Technology Ube College Japan Department of Mechanical Engineering Graduate School of Science and Technology for Innovation Yamaguchi University Japan Quality Analysis Center Research & Development Center Innovation & Technology Division YANMAR HOLDINGS CO.

When operating a tractor on a pavement, its vibration is greatly affected by the lug excitation force, which is caused by the interaction between the road and agricultural tire. Therefore, it is important to understand the characteristics of the lug excitation force to elucidate the mechanism of tractor vibration. However, it is difficult to directly measure the lug excitation force during rolling motion owing to the requirements of complicated measurement methods. Therefore, no studies have determined the lug excitation force. In this study, an agricultural tire is modeled as a 3-dimensional rigid ring model, which is useful for estimating the lug excitation force. Consequently, a new technique to determine the lug excitation force is presented. The shaft displacement and shaft force during rolling motion are measured in 3-dimensions through rolling test, and the lug excitation force is determined from the test data. The characteristics of the lug excitation and shaft forces are investigated, including the correlation between these and the tire vibration characteristics. Furthermore, the transfer characteristics of the lug excitation force with respect to the shaft force are analyzed, and the effect of the tire vibration characteristics on the transfer characteristics is examined. The developed technique is very useful in reducing tractor vibration caused by the lug excitation force. © 2021 Elsevier B.V.. All rights reserved.

Although wave glider has many excellent features that other unmanned surface vehicles cannot compare with, and has a wide application prospect, it is still a small unmanned surface vehicle with limited ability. In practical application, the wave glider has many defects such as poor resistance to sabotage, limited carrying capacity, unable to get in position quickly and so on. While the fatal flaw of the wave glider is that it is easily damaged by man due to its low speed on the surface. Therefore, the wave glider requires continued technological innovation. This paper presents a design scheme of wave glider capable of autonomous vigilance and emergency diving. The feasibility and challenges of the scheme are preliminarily demonstrated, which provides a way to improve the survivability of wave gliders against man-made damage. © 2022 by the International Society of Offshore and Polar Engineers (ISOPE).
