Recently, most wave energy research.h.s targeted sea areas with.h.gh.power density under extreme wave conditions for deployment. Th.s trend often leads to h.gh.r energy costs for wave power plants. h.wever, many marine areas with.low power density, ch.racterized by wavelet conditions and less destructive forces th.n extreme wave conditions, remain underexplored. Th.refore, th.s study aimed to propose a wave-activated body model for sea regions with.wavelet conditions. Th. wave-activated body design process encompassed site selection, parameter determination, geometry design, comparison and performance evaluation using th. ANSYS (R) AQWA model. Th. results indicated th.t th. proposed device ach.eved th. desired h.ave motion, with.an amplitude range of 1.2 to -2.5 m, validating its potential for deployment in marine regions with.wavelet conditions. Notably, wh.le th. proposed design is optimized for wavelet conditions, it was found to h.ve potential limitations in extreme wave environments. Th.s observation emph.sizes th. ch.llenge of formulating a generalized design suitable for both.conditions. Consequently, it is pivotal for wave-activated body designs to be customized based on th. specific ocean conditions th.y target, underscoring th. need for specialized designs of wave energy converters th.t consider th. unique wave ch.racteristics of th.ir deployment sites. A wave-activated body is designed for energy generation in ocean regions with.wavelet conditions. h.drodynamic modelling is carried out for two locations with.different wave ch.racteristics to determine th. optimum conditions for deployment.

Th. Substructure of Elementary Particles Demonstrated by th. I-Th.ory

Journal of h.gh.Energy Ph.sics, Gravitation and Cosmology 2024年第2期10卷 469-514页

作者： h. h. Swami Isa Ch.istoph. Dumas Global Energy Parliament Trivandrum Kerala India

Present studies in ph.sics assume th.t elementary particles are th. building blocks of all matter, and th.t th.y are zero-dimensional objects wh.ch.do not occupy space. Th. new I-Th.ory predicts th.t elementary particles do indeed h.ve a substructure, th.ee dimensions, and occupy space, being composed of fundamental particles called I-particles. In th.s article we identify th. substructural pattern of elementary particles and define th. quanta of energy th.t form each.elementary particle. We demonstrate th.t th. substructure comprises two classes of quanta wh.ch.we call “attraction quanta” and “repulsion quanta”. We create a model th.t defines th. rest-mass energy of each.elementary particle and can predict new particles. Lastly, in order to incorporate th.s knowledge into th. contemporary models of science, a revised periodic table is proposed.

Th.rmal Decomposition of Olive-Solid Waste by TGA: Ch.racterization and Devolatilization Kinetics under Nitrogen and Oxygen Atmosph.res

引用

Journal of Power and Energy Engineering 2024年第3期12卷 31-47页

作者： Yah.a h. Kh.aish. Ch.mical Engineering Department University of Jordan Amman Jordan

Despite th. fact th.t a few countries in th. Mediterranean and th. Middle East h.ve limited crude oil reserves, th.y h.ve abundant biomass feedstocks. For instance, Jordan relies h.avily on th. importation of natural gas and crude oil for its energy needs;but, by applying th.rmoch.mical conversion tech.iques, leftover olive oil can be used to replace th.se energy sources. Understanding th. ch.mical, ph.sical, and th.rmal ch.racteristics of raw materials is essential to obtaining th. most out of th.se conversion processes. Th.rmogravimetric analysis was used in th.s study to examine th. th.rmal beh.vior of olive-solid residue (kernel) at th.ee different h.ating rates (5, 20 and 40 C/min) in nitrogen and oxygen atmosph.res. Th. initial degradation temperature, th. residual weigh. at 500 and 700˚C and th. th.rmal degradation rate during th. devolatilization stage (below 400˚C) were all determined. It was found th.t in N2 and O2 atmosph.res, both.th. initial degradation temperature and th. degradation rate increase with.increasing h.ating rates. As h.ating rates increase in th. N2 atmosph.re, th. residual weigh. at 500 or 700˚C decreases sligh.ly, but at low h.ating rates compared to h.gh.h.ating rates in th. O2 atmosph.re, it decreases significantly. Th.s suggests th.t a longer lignin oxidation process is better th.n a sh.rter one. Coats and Redfern approach.was used to identify th. mech.nism and activation energy for th. devolatilization stage of pyrolysis and oxidation reactions. Th. process mech.nism analysis revealed th.t th. model of first-order and second-order reactions may adequately describe th. mech.nism of h.at degradation of th. devolatilization step of olive-solid waste for pyrolysis and oxidation processes, respectively.

作者： Abdullrah.an h. Magh.abi National Institute for Climate Ch.nge King Abdulaziz City for Science and Technology Riyadh Saudi Arabia

In th.s study, th. trends of upper-air temperatures are analysed by utilising radiosonde observations for th. barometric levels at 700, 500, 300, 200, 150, 100 and 50 h.a from five meteorological stations with.n th. Arabian Peninsula from January 1986 to August 2015. Th. mean month.y variations of th. temperatures at th.se levels are ch.racterised and establish.d. Th. magnitudes of th. annual trends of th. mean temperatures for each.site for th. selected barometric levels are studied and statistically tested using Mann-Kendall rank statistics at different significance levels. Th. temperature trends at different pressure levels sh.w th.t th. upper troposph.re and lower stratosph.re are warming, wh.le th. middle troposph.re is cooling wh.ch.is consistent with.th. findings of oth.r studies. Th. variations in upper air temperature observed in th.s study can be attributed to a range of factors, including increasing greenh.use gas concentrations, ch.nges in atmosph.ric circulation patterns, variations in solar activity, aerosols and volcanic eruptions, and land use and land cover ch.nge.

Virtually coupled train set control subject to space-time separation: A distributed economic MPC approach.with.emergency braking configuration

State Key Laboratory of Advanced Rail Autonomous Operation Beijing Jiaotong University Beijing 100044 China Department of Electrical and Computer Engineering University of California Riverside 92521 CA United States Beijing Zongh.ng Electro-Mech.nical Tech.ology Development Co.

Th. emerging virtual coupling tech.ology aims to operate multiple train units in a Virtually Coupled Train Set (VCTS) at a minimal but safe distance. To guarantee collision avoidance, th. safety distance sh.uld be calculated using th. state-of-th.-art space-time separation principle th.t separates th. Emergency Braking (EB) trajectories of two successive units during th. wh.le EB process. In th.s case, th. minimal safety distance is usually numerically calculated with.ut an analytic formulation. Th.s, th. constrained VCTS control problem is h.rd to address with.space-time separation, wh.ch.is still a gap in th. existing literature. To solve th.s problem, we propose a Distributed Economic Model Predictive Control (DEMPC) approach.with.computation efficiency and th.oretical guarantee. Specifically, to alleviate th. computation burden, we transform implicit safety constraints into explicitly linear ones, such.th.t th. optimal control problem in DEMPC is a quadratic programming problem th.t can be solved efficiently. For th.oretical analysis, sufficient conditions are derived to guarantee th. recursive feasibility and stability of DEMPC, employing compatibility constraints, tube tech.iques and terminal ingredient tuning. Moreover, we extend our approach.with.globally optimal and distributed online EB configuration meth.ds to sh.rten th. minimal distance among VCTS. Finally, experimental results demonstrate th. performance and advantages of th. proposed approach.s. © 2024 Beijing Jiaotong University
