Groundwater vulnerability assessment is a crucial step in th. efficient management of groundwater resources,especially in areas with.intensive anth.opogenic activities and groundwater *** th. present study,th. DRASTIc meth.d was applied using Geograph.c Information System(GIS)to delineate groundwater vulnerability zones in th. Erbil Dumpsite area,central Erbil Basin,North.*** sh.wed th.t th. area was classified into four vulnerability classes:Very low(16.97%),low(27.67%),moderate(36.55%)and h.gh.18.81%).Th. south.rn,south.eastern and north.rn parts of th. study area exh.bited th. h.gh.st vulnerability potential,wh.le th. central-north.rn,north.rn and north.western regions displayed th. lowest vulnerability ***,results of th. single-parameter sensitivity analysis indicated th.t amongst th. seven DRASTIc parameters,th. unsaturated zone and th. aquifer media were th. most influencing *** conclustion,th. correlation of 25 nitrate concentration values with.th. final vulnerability map,assessed using th. Pearson correlation coefficient,yielded a satisfac.ory result of R=0.72.

Th. Unified Field

Journal of Modern Ph.sics 2024年第7期15卷 1010-1035页

作者： Joseph.h. (cass) Forrington Managing Editor Journal of Cosmology California USA

Th.s is a Unified Field description based on th. h.lograph.c Time Dilation cosmology, TDc, model, wh.ch.is an eternal continuum evolving forward in th. forward direction of time, at th. speed of ligh., c, at an invariant 1 s/s rate of time. Th.s is th. Fundamental Direction of Evolution, FDE. Th.re is also an evolution down time dilation gradients, th. Gravitational Direction of Evolution, GDE. Th.se evolutions are gravity, wh.ch.is th. evolutionary force in time. Gravitational velocities are compensation for th. difference in th. rate of time, dRt, in a dilation field, and th. dRtis equal to th. compensatory velocity’s percentage of c, and is a measure of th. force in time inducing th. velocity. In applied force induced velocities, th. dRt is a measure of th. resistance in time to th. induced velocity, wh.ch.migh. be called “anti-gravity” or “negative gravity”. Th. two effects keep th. continuum uniformly evolving forward at c. It is demonstrated th.t gravity is already a part of th. electromagnetic field equations in way of th. dRt element contained in th. TDc velocity formula. Einstein’s energy formula is defined as a velocity formula and a modified version is used for ch.rged elementary particle solutions. A time dilation-based derivation of th. Lorentz force ties gravity directly to th. electromagnetic field proving th. unified field of gravity and th. EMF. It is noted h.w we could possibly create gravity drives. Th.s is followed by a discussion of black h.les, proving supermassive objects, like massive black h.le singularities, are impossible, and th.t black h.les are massless Magnetosph.ric Eternally collapsing objects (MEcos) th.t are vortices in spacetime. .

Th.s paper validates th. optimal operation for a grid-connected double-fed induction generator (DFIG) in an oscillating water column power plant (oWcPP). Th.s study presents a novel optimization tech.ique called th. circulatory system-based optimization (cSBo) approach.to develop six adaptive fuzzy logic controllers (AFLcs) with.30 parameters and compare th.m to ch.otic-billiards optimization (c-Bo) and genetic algorith. (GA). Th. proposed controller is also compared with.a proportional-integral differential (PID) controller based on a self-adaptive global-best h.rmony search.(SGh.). cSBo-based AFLcs are fully investigated under different scenarios and experimented with.using a real-time interface DSP1104. Th. results of using cSBo-AFLcs revealed a fast time response, fast convergence, less oversh.ot and minimal error compared with.th.se ach.eved with.c-Bo-AFLc, SGh.-PID and GA-AFLc during different case studies. Th. cSBo-based AFLcs ensure maximum power from th. DFIG in an oWcPP and enh.nce dynamic response with.very low errors. Th. results sh.w th.t th. cSBo sh.ws better power tracking by 25% as compared with.c-Bo, by 45% wh.n compared with.th. GA and by 56% wh.n compared with.PID. Moreover, th. integral absolute errors of six controllers are investigated to demonstrate th. feasibility of cSBo-AFLc. Th. root mean square of th. errors of six controllers using cSBo is improved by 68.27% wh.n compared with.GA, by 22.57% wh.n compared with.c-Bo and by 38.42% wh.n compared with.PID. Th.se indicators demonstrate th. feasibility of cSBo wh.n compared with.oth.r algorith.s with.th. same oWcPP. Th.s paper validates th. optimal operation of a grid-connected double-fed induction generator in an oscillating water column using a novel optimization tech.ique called th. circulatory system-based optimization approach. Experiments using a real-time simulator demonstrate th. feasibility of th. approach.wh.n compared with.oth.r algorith.s. Graph.cal Abstract

In areas with.large temperature differences, th. uneven distribution of temperatures in th. cRTS III ballastless track slab due to daytime sunligh. can cause warpage deformation, leading to periodic rail irregularities th.t increase th. wh.el-rail impact of h.gh.speed veh.cles and accelerate track structure damage. Th.refore, it is necessary to study th. dynamic contact relationsh.p between th. composite slab and th. base plate during veh.cle running. Th. results of th. study sh.w th.t: 1) Under th. influence of temperature gradients, th. composite slab tends to deform elliptically. With.a positive temperature gradient, th. middle part of th. track slab bulges upward, causing th. slab to be supported by its four corners. conversely, with.a negative temperature gradient, th. four corners of th. track slab bulge upward, resulting in th. slab being supported by its center. 2) Temperature gradients can lead to separation between th. composite slab and th. base plate, reducing th. contact area between layers. During veh.cle running, th. contact area between layers gradually increases, but th. separation cannot be completely c.osed. 3) Th. temperature gradient significantly affects th. vertical displacement of th. track. Th. vertical displacement in th. middle of th. slab increases with.a positive temperature gradient. In contrast, th. vertical displacement at th. ends of th. slab increases with.a negative temperature gradient. 4) Th. stress of self-compacting concrete at th. side position significantly increases under a positive temperature gradient, with.th. vertical stress increasing by 2.7 times wh.n th. temperature gradient increases from 0 to 90 ℃·m−1. © 2024

Th. Balise Transmission Module (BTM) unit of th. on-board train control system is a crucial component. Due to its unique installation position and complex environment, th.s unit h.s a h.gh.r fault rate with.n th. on-board train control system. To conduct fault prediction for th. BTM unit based on actual fault data, th.s study proposes a prediction meth.d combining reliability statistics and mach.ne learning, and ach.eves th. fusion of prediction results from different dimensions th.ough.multi-meth.d interactive validation. Firstly, a meth.d for predicting equipment fault time targeting batch.equipment is introduced. Th.s meth.d utilizes reliability statistics to construct a model of th. remaining faultless operating time distribution considering uncertainty, th.reby predicting th. remaining faultless operating probability of th. BTM unit. Secondly, considering th. complexity of th. BTM unit's fault mech.nism, th. small sample size of fault cases, and th. potential presence of multiple fault features in fault text records, an individual-oriented fault prediction meth.d based on Bayesian-optimized Gradient Boosting Regression Tree (Bayes-GBRT) is proposed. Th.s meth.d ach.eves better prediction results compared to linear regression algorith.s and random forest regression algorith.s, with.an average absolute error of only 0.224 years for predicting th. fault time of th.s type of equipment. Finally, a multi-meth.d interactive validation approach.is proposed, enabling th. fusion and validation of multi-dimensional results. Th. results indicate th.t th. predicted fault time and th. actual fault time conform to a log-normal distribution, and th. parameter estimation results are basically consistent, verifying th. accuracy and effectiveness of th. prediction results. Th. above research.findings can provide tech.ical support for th. maintenance and modification of BTM units, effectively reducing maintenance costs and ensuring th. safe operation of h.gh.speed railway, th.s h.
