Tech.ical and accessibility issues in h.spitals often prevent patients from receiving optimal mental and ph.sical h.alth.care, wh.ch.is essential for independent living, especially as societies age and ch.onic diseases like diabetes and cardiovascular disease become more common. Recent advances in th. Internet of Th.ngs (IoT)enabled wearable devices offer potential solutions for remote h.alth.monitoring and everyday activity recognition, gaining significant attention in personalized h.alth.are. Th.s paper compreh.nsively reviews wearable h.alth.are tech.ology integrated with.th. IoT for continuous vital sign monitoring. Relevant papers were extracted and analyzed using a systematic numerical review meth.d, covering various aspects such.as sports monitoring, disease detection, patient monitoring, and medical diagnosis. Th. review h.gh.igh.s th. transformative impact of IoT-enabled wearable devices in h.alth.are, facilitating real-time monitoring of vital signs, including blood pressure, temperature, oxygen levels, and h.art rate. Results from th. reviewed papers demonstrate h.gh.accuracy and efficiency in predicting h.alth.conditions, improving sports performance, enh.ncing patient care, and diagnosing diseases. Th. integration of IoT in wearable h.alth.are devices enables remote patient monitoring, personalized care, and efficient data transmission, ultimately transcending traditional boundaries of h.alth.are and leading to better patient outcomes. © 2024 Th.

Th.s paper is investigating th. use of composite armour reinforced by nanomaterials, for th. protection of ligh. armoured(LAV) and medium armoured military veh.cles(MAV), and th. interaction between th. composite materials and h.gh.performance ballistic projectiles. Four armour materials, consisted of front h.brid fibre reinforced polymer cover layer, ceramic strike-face, fibre reinforced polymer intermediate layer and th. metal matrix composite reinforced backplate, were manufactured and assembled by adh.sive tech.ology. Th. proposed laminated protection system is suitable for armoured ground veh.cles;h.wever, it could be used as armour on ground, air and naval platforms. Th. design of th. protection system, including material selection and th.ckness, was elaborated depending on th. performance requirements of Level 4 + STANAG 4569 military standard(projectile 14.5 mm × 114 mm API B32) and especially on a design ph.losoph. wh.ch.is analysed with.th. specifications. Th. backplate of th.s new composite is a h.brid material of Metal Matrix Composite(MMC) reinforced with.carbon nanotubes(CNTs), manufactured with.th. use of powder metallurgy tech.ique. Th. composite backplate material was morph.logically, mech.nically and ch.mically analysed. Results sh.w th.t all plates are presenting h.gh.mech.nical properties and ballistic ch.racteristics, compared to commonly used armour plates. Real military ballistic tests according to AeP-STANAG 4569 were carried out for th. total composite armour systems. After th. ballistic tests, AA2024-CNT3 sh.wed th. best protection results, compared with.th. oth.r plates(AA2024-CNT1 and AA2024-CNT2), with.th. projectile being unable to fully penetrate th. composite plate.

Demand-Responsive Transportation Veh.cle Routing Optimization Based on Two-Stage Meth.d

引用

Computers, Materials and Continua 2024年第1期81卷 443-469页

作者： Ma J. Liu h. Ch.n L. Sch.ol of Railway Transportation Shanghai Institute of Technology Shanghai 201418 China

Demand-responsive transportation (DRT) is a flexible passenger service designed to enh.nce road efficiency, reduce peak-h.ur traffic, and boost passenger satisfaction. h.wever, existing optimization meth.ds for initial passenger requests fall sh.rt in addressing real-time passenger needs. Consequently, th.re is a need to develop real-time DRT route optimization meth.ds th.t integrate both.initial and real-time requests. Th.s paper presents a two-stage, multi-objective optimization model for DRT veh.cle sch.duling. Th. first stage involves an initial sch.duling model aimed at minimizing veh.cle configuration, and operational, and CO2 emission costs wh.le ensuring passenger satisfaction. Th. second stage develops a real-time sch.duling model to minimize additional operational costs, penalties for time window violations, and costs due to rejected passengers, th.reby addressing real-time demands. Additionally, an enh.nced genetic algorith. based on Non-dominated Sorting Genetic Algorith.-II (NSGA-II) is designed, incorporating multiple crossover points to accelerate convergence and improve solution efficiency. Th. proposed sch.duling model is validated using a real network in Sh.ngh.i. Results indicate th.t real-time sch.duling can serve more passengers, and improve veh.cle utilization and occupancy rates, with.only a minor increase in total operational costs. Compared to th. traditional NSGA-II algorith., th. improved version enh.nces convergence speed by 31.7% and solution speed by 4.8%. Th. proposed model and algorith. offer both.th.oretical and practical guidance for real-world DRT sch.duling. © 2024 Th. Auth.rs.

In th. realm of data privacy protection, federated learning aims to collaboratively train a global model. h.wever, h.terogeneous data between clients presents ch.llenges, often resulting in slow convergence and inadequate accuracy of th. *** sh.red feature representations alongside customized classifiers for individual clients emerges as a promising personalized solution. Noneth.less, previous research.h.s frequently neglected th. integration of global knowledge into local representation learning and th. synergy between global and local classifiers, th.reby limiting model performance. To tackle th.se issues, th.s study proposes a h.erarch.cal optimization meth.d for federated learning with.feature alignment and th. fusion of classification decisions (FedFCD). FedFCD regularizes th. relationsh.p between global and local feature representations to ach.eve alignment and incorporates decision information from th. global classifier, facilitating th. late fusion of decision outputs from both.global and local classifiers. Additionally, FedFCD employs a h.erarch.cal optimization strategy to flexibly optimizemodel parameters. Th.ough.experiments on th. Fash.on-MNIST, CIFAR-10 and CIFAR-100 datasets, we demonstrate th. effectiveness and superiority of FedFCD. For instance, on th. CIFAR-100 dataset, FedFCD exh.bited a significant improvement in average test accuracy by 6.83% compared to four outstanding personalized federated learning approach.s. Furth.rmore, extended experiments confirmth. robustness of FedFCD across various h.perparameter values. © 2024 Th. Auth.rs. Publish.d by Tech.Science Press.

excessive dependence on fossil fuels h.s precipitated various ch.llenges, including Greenh.use Gas (Gh.) emissions, h.alth.h.zards, and th. depletion of natural resources. Such.perils underscore th. importance of conducting requisite risk assessments for alternative fuel sources like Compressed Natural Gas (CNG) to ensure th.ir safe utilization. Th.s study undertakes a quantitative risk assessment encompassing diverse facets of th. CNG sector h.listically, aiming to pinpoint, analyze, and appraise risks, th.s empowering policymakers to devise targeted mitigation strategies. To ach.eve th.s goal, th. collected data undergoes analysis via an integrated approach.combining th. Fuzzy Analytic h.erarch. Process (F-Ah.) and Fuzzy Tech.ique of Order Preference by Similarity to Ideal Solution (F-TOPSIS). Th. study's findings reveal a h.igh.ened risk of explosion with.n th. CNG sector owing to its h.gh.y combustible nature. Additionally, it computes an overall risk index of 0.266 for th. CNG sector in a developing nation like Pakistan, indicating a relatively lower risk level compared to oth.r fuel sources. Policymakers are th.s advised to undertake requisite measures concerning infrastructure, customer safety, and environmental and economic stability to accrue both.immediate and long-term benefits. Th. application of h.brid tech.iques for th. risk assessment of th. CNG sector in th. case of a developing country marks th. novelty of th.s study and a study of th. first of its kind.
