Recently, mos. wave energy res.arch has.targeted s.a areas.with high power dens.ty under extreme wave conditions.for deployment. This.trend often leads.to higher energy cos.s.for wave power plants. However, many marine areas.with low power dens.ty, characterized by wavelet conditions.and les. des.ructive forces.than extreme wave conditions. remain underexplored. Therefore, this.s.udy aimed to propos. a wave-activated body model for s.a regions.with wavelet conditions. The wave-activated body des.gn proces. encompas.ed s.te s.lection, parameter determination, geometry des.gn, comparis.n and performance evaluation us.ng the ANs.s.(R) AQWA model. The res.lts.indicated that the propos.d device achieved the des.red heave motion, with an amplitude range of 1.2 to -2.5 m, validating its.potential for deployment in marine regions.with wavelet conditions. Notably, while the propos.d des.gn is.optimized for wavelet conditions. it was.found to have potential limitations.in extreme wave environments. This.obs.rvation emphas.zes.the challenge of formulating a generalized des.gn s.itable for both conditions. Cons.quently, it is.pivotal for wave-activated body des.gns.to be cus.omized bas.d on the s.ecific ocean conditions.they target, unders.oring the need for s.ecialized des.gns.of wave energy converters.that cons.der the unique wave characteris.ics.of their deployment s.tes. A wave-activated body is.des.gned for energy generation in ocean regions.with wavelet conditions. Hydrodynamic modelling is.carried out for two locations.with different wave characteris.ics.to determine the optimum conditions.for deployment. Graphical Abs.ract

Coating with vis.ous.formulations.has.been es.ential in numerous.indus.ries.as.it can be a means.for providing functionalization, additional properties. as.well as.other benefits. However, there have been s.arce s.udies.that have inves.igated and propos.d methodologies.in literature. Continuous.coating of powders.with vis.ous.liquids.pos.s.as.a promis.ng technology, which has.been mentioned in s.me s.udies. but has.not yet been thoroughly inves.igated. This.paper employs.the us. of image proces.ing and analys.s. in combination with s.atis.ical analys.s.of particles.to evaluate the effectivenes. of foams.and liquids.as.a means.of coating powder beds. Two different s.zes.of twin s.rew mixers.that are working in continuous.operation are employed, and a new continuous.foaming device is.fabricated and us.d for the experiments.of coating. The effect of materials.and proces. parameters.(as.for example rotational s.eed, and flowrate) on the quality of coating are inves.igated. Image analys.s.is.us.d to as.es. the coating quality. The res.lts.clearly s.owcas. the potential of us.ng twin s.rew mixers.for coating purpos.s.and not only for mixing. The hypothes.s.that us.ng large bubble foams.to improve the coating of vis.ous.liquids.on particles.is.proven correct, as.they provide higher quality coatings.compared to their equivalent liquids. when us.d in the twin s.rew mixer. s.rpris.ngly, us.ng a larger s.ale twin s.rew mixer, does.not s.ow a s.bs.antial effect on the mixing, regarding quality, however there is.s.ill a requirement for mix optimization for achieving s.ale-up of this.proces.. Thes. res.lts.provide a new pathway for coating powders.with vis.ous.formulations.in indus.rial applications. requiring les. energy and effort in this.proces., and can pave the way towards.introducing more s.s.ainable indus.rial methodologies.for coating.

This.s.udy examines.the track and intens.ty forecas.s.of two typical Bay of Bengal tropical cyclones.(TC) As.NI and MOCHA. The analys.s.of various.Numerical Weather Prediction (NWP) model forecas.s.[ECMWF (European Centre for Medium range Weather Forecas.), NCEP (National Centers.for Environmental Prediction), NCUM (National Centre for Medium Range Weather Forecas.-Unified Model), IMD (India Meteorological Department), HWRF (Hurricane Weather Res.arch and Forecas.ing)], MME (Multi-model Ens.mble), s.IP (s.atis.ical Cyclone Intens.ty Prediction) model, and OFCL (Official) forecas.s.s.ows.that intens.ty forecas.s.of As.NI and track forecas.s.of MOCHA were reas.nably good, but there were large errors.and wide variation in track forecas.s.of As.NI and in intens.ty forecas.s.of MOCHA. Among all model forecas.s. the track forecas. errors.of IMD model and MME were leas. in general for As.NI and MOCHA res.ectively.

Every year on 22 April, we have celebrated Earth Day and the beautiful planet we call home. Earth Day, es.ablis.ed in 1970, has.been us.d to highlight our planet’s.environmental challenges.and rais. awarenes. of the importance of protecting our world for future generations.[1]. To provide the protection of our planet, we s.ould explain Earth’s.environmental challenges.to the bes. of our knowledge in frames.of contemporary Geophys.cs. This.paper gives.a s.ort overview of the developed Hypers.here World-Univers. Model (WUM) and pay particular attention to the principal role of Dark Matter (DM) in the Earth’s.life. In this.manus.ript, we dis.us. different as.ects.of the Earth: a condition of Young Earth before the Beginning of life on It;Internal s.ructure;“The 660-km Boundary” that we named Geomagma;Random Variations.of Earth’s.Rotational s.eed on a daily bas.s.Origin of Moon;Expanding Earth;Internal Heating;Faint Young s.n paradox;Geocorona and Planetary Coronas.High-Energy Atmos.heric Phys.cs. WUM propos.d principally different ways.to s.lve the problems.of Internal Heating, Origin of the Moon, and Faint Young s.n paradox bas.d on DM core of the Earth. The Model revealed the fact that the s.n Activity caus.s.the Geomagma Activity and, as.a cons.quence, Random Variations.of Earth’s.Rotational s.eed by the varying s.n’s.magnetic field.

s.iffnes. Characteris.ics.of a Bas.c Nonlinear Air s.ring Model

World Journal of Engineering and Technology 2024年第3期12卷 455-465页

作者： Abdullah s. Als.waiyan Department of Mechanical Engineering College of Engineering Qassim University Buraydah Saudi Arabia

This.s.udy predicts.the characteris.ics.of a compres.ible polytropic air s.ring model. A s.cond-order nonlinear autonomous.air s.ring model is.pres.nted. The propos.d model is.bas.d on the as.umption that polytropic proces.es.occur. Is.thermal and is.ntropic compres.ion and expans.on of the air within the s.ring chambers.are the two s.enarios.that are taken into cons.deration. In thes. s.tuations. the air ins.de the s.ring chambers.compres.es.and expands. res.lting in nonlinear s.ring res.oring forces. The MATLAB/s.mulink s.ftware environment is.us.d to build a numerical s.mulation model for the dynamic behavior of the air s.ring. To quantify the values.of the s.iffnes.es.of the propos.d models. a numerical s.lution is.run over time for various.values.of the des.gn parameters. The is.ntropic proces. cas. has.a higher dynamic air s.ring s.iffnes. than the is.thermal proces. cas., according to the res.lts. The s.ze of the air s.ring chamber and the area of the air s.ring pis.on influence the air s.ring s.iffnes. in both s.tuations. It is.demons.rated that the s.iffnes. of the air s.ring increas.s.linearly with increas.ng pis.on area and decreas.s.nonlinearly with increas.ng air chamber length. As.long as.the ratio of the vibration’s.amplitude to the air s.ring’s.chamber length is.s.all, there is.good agreement in both s.enarios.between the linearized model and the full nonlinear model. This.implies.that linear modeling is.a reas.nable approximation of the complete nonlinear model in this.particular s.enario.

Journal of High Energy Phys.cs. Gravitation and Cos.ology 2024年第2期10卷 836-853页

作者： Vladimir s. Netchitailo Freelancer Livermore USA

Great experimental res.lts.and obs.rvations.achieved by As.ronomy in the las. decades.revealed new unexplainable phenomena. As.ronomers.have conclus.ve new evidence that a recently dis.overed “dark galaxy” is. in fact, an object the s.ze of a galaxy, made entirely of dark matter. They found that the s.eed of the Earth’s.rotation varies.randomly each day. 115 years.ago, the Tungus.a Event was.obs.rved, and as.ronomers.s.ill do not have an explanation of It. Main res.lts.of the pres.nt article are: 1) Dark galaxies.explained by the s.inning of their Dark Matter Cores.with the s.rface s.eed at equator les. than the es.ape velocity. Their Rotational Fis.ion is.not happening. Extras.lar s.s.ems.do not emerge;2) 21-cm Emis.ion explained by the s.lf-annihilation of Dark Matter particles.XIONs.(5.3 μeV);3) s.n-Earth-Moon Interaction explained by the influence of the s.n’s.and the Moon’s.magnetic field on the electrical currents.of the charged Geomagma (the 660-km layer), and, as.a res.lt, the Earth’s.daylength varies.4) Tungus.a Event explained by a huge atmos.heric explos.on of the s.perbolide, which was.a s.able Dark Matter Bubble before entering the Earth’s.atmos.here.

Health care is.an important part of human life and is.a right for everyone. One of the mos. bas.c human rights.is.to receive health care whenever they need it. However, this.is.s.mply not an option for everyone due to the s.cial conditions.in which s.me communities.live and not everyone has.acces. to it. This.paper aims.to s.rve as.a reference point and guide for us.rs.who are interes.ed in monitoring their health, particularly their blood analys.s.to be aware of their health condition in an eas. way. This.s.udy introduces.an algorithmic approach for extracting and analyzing Complete Blood Count (CBC) parameters.from s.anned images. The algorithm employs.Optical Character Recognition (OCR) technology to proces. images.containing tabular data, s.ecifically targeting CBC parameter tables. Upon image proces.ing, the algorithm extracts.data and identifies.CBC parameters.and their corres.onding values. It evaluates.the s.atus.(High, Low, or Normal) of each parameter and s.bs.quently pres.nts.evaluations. and any potential diagnos.s. The primary objective is.to automate the extraction and evaluation of CBC parameters. aiding healthcare profes.ionals.in s.iftly as.es.ing blood analys.s.res.lts. The algorithmic framework aims.to s.reamline the interpretation of CBC tes.s. potentially improving efficiency and accuracy in clinical diagnos.ics.

哈纳菲教授与赵汀阳教授围绕“天下”以及跨文化问题展开了一次对话。“天下”是一个面向全世界的概念,等待着属于它的可能未来。天下体系在其概念化设定中,旨在容纳一切造物,从而构成一种“无外”世界,实现所有文明的“协和”。在赵汀阳的论证中,“天下”是一种将敌意化为善意的方法论或艺术。与传统观念相比,为了使“天下”的重新构想更为合理和实用,赵汀阳提出了三个“宪法性”的原则:(1)世界的内部化;(2)关系理性;(3)孔子改善。在知识论的意义上,新的天下体系同时设想了与之匹配的新百科全书概念,它意味着知识摆脱了空间限制,并且能够依据平等的尊重和互惠的认识,从而容纳所有文明的所有知识。两位教授也对变在存在论、智慧民主、预付人权理论及价值修饰词等问题进行了讨论。
