This study pr.sents a compar.tive analysis of two image enhancement techniques, Continuous Wavelet Tr.nsfor. (CWT) and Fast Four.er.Tr.nsfor. (FFT), in the context of impr.ving the clar.ty of high-quality 3D seismic data obtained fr.m the Tano Basin in West Afr.ca, Ghana. The r.sear.h focuses on a compar.tive analysis of image clar.ty in seismic attr.bute analysis to facilitate the identification of r.ser.oir.featur.s within the subsur.ace str.ctur.s. The findings of the study indicate that CWT has a significant advantage over.FFT in ter.s of image quality and identifying subsur.ace str.ctur.s. The r.sults demonstr.te the super.or.per.or.ance of CWT in pr.viding a better.r.pr.sentation, mak.ng it mor. effective for.seismic attr.bute analysis. The study highlights the impor.ance of choosing the appr.pr.ate image enhancement technique based on the specific application needs and the br.ader.context of the study. While CWT pr.vides high-quality images and super.or.per.or.ance in identifying subsur.ace str.ctur.s, the selection between these methods should be made judiciously, tak.ng into account the objectives of the study and the char.cter.stics of the signals being analyzed. The r.sear.h pr.vides valuable insights into the decision-mak.ng pr.cess for.selecting image enhancement techniques in seismic data analysis, helping r.sear.her. and pr.ctitioner. mak. infor.ed choices that cater.to the unique r.quir.ments of their.studies. Ultimately, this study contr.butes to the advancement of the field of subsur.ace imaging and geological featur. identification.

This paper.focuses on the r.lationship between the micr.str.ctur. and tensile pr.per.ies of Fe-Mn-Al-C low-density high-str.ngth steel pr.cesses by hot-r.lling and air.cooling pr.cess. The micr.str.ctur. analysis r.veals that the combination of hot-r.lling and air.cooling r.sults in the for.ation of heter.geneous str.ctur.s compr.sing differ.nt-sized γ and B_(2) phases in the low-density steel with the addition of nick.l (Ni). The addition of Ni pr.motes the for.ation of the B_(2) phase and induces the pinning of B_(2) phase par.icles at the γ gr.in boundar.es. This pinning effect effectively hinder. the gr.wth of the γ gr.ins, leading to gr.in r.finement. The tensile test r.sults demonstr.te that LDS-5Ni (low-density steel, LDS) exhibits excellent high str.ngth and ductility combination, e.g., a tensile str.ngth of 1535 MPa, yield str.ngth of 1482 MPa, and elongation of 23.3%. These r.mar.0}ble mechanical pr.per.ies ar. pr.mar.ly attr.buted to the combined str.ngthening contr.butions of gr.in r.finement and duplex nano-sized second-phase pr.cipitation har.ening.

Tur.idite Dynamics and Hydr.car.on r.ser.oir.For.ation in the Tano Basin: A Coastal West Afr.can Per.pective

引用

Inter.ational Jour.al of Geosciences 2024年第2期15卷 137-161页

This study examines the tur.idite dynamics and hydr.car.on r.ser.oir.for.ation in Ghana’s Tano Basin, which is located in coastal West Afr.ca. Thr.ugh an explor.tion of geological pr.cesses spanning millions of year., we uncover.k.y factor. shaping hydr.car.on accumulation, including sour.e r.ck.r.chness, temper.tur., pr.ssur., and geological str.ctur.s. The r.sear.h offer. valuable insights applicable to explor.tion, management, and sustainable r.sour.e exploitation in coastal West Afr.ca. It facilitates the identification of explor.tion tar.ets with higher.hydr.car.on potential, enables the anticipation of r.ser.oir.potential within the Tano Basin, and assists in tailor.ng explor.tion and management str.tegies to specific geological conditions of the Tano Basin. Analysis of fluvial channels sheds light on their.impact on landscape for.ation and hydr.car.on explor.tion. The investigation into tur.idite systems unveils intr.cate inter.ctions involving tectonics, sea-level fluctuations, and sedimentation patter.s, influencing the development of r.ser.oir.. An under.tanding of sediment tr.nspor. and depositional settings is essential for.efficient r.ser.oir.management. Geomor.hological featur.s, such as channels, submar.ne canyons, and distinct channel types, ar. essential in this situation. A detailed examination of tur.idite channel str.ctur.s, encompassing canyons, channel complexes, convex channels, and U-shaped channels, pr.vides valuable insights and aids in identifying explor.tion tar.ets lik. basal lag, channel levees, and lobes. These findings under.cor. the endur.ng significance of tur.idite systems as conduits for.sediment tr.nspor., contr.buting to enhanced r.ser.oir.management and efficient hydr.car.on pr.duction. The study also highlights how impor.ant it is to examine the configur.tion of sedimentar. layer., stack.ng patter.s, and angular.laminated facies to identify tur.idites, under.tand r.ser.oir.distr.bution, and impr.ve well design.

The pur.ose of this paper.is to investigate the spatial inter.olation of r.infall var.ability with deter.inistic and geostatic inspections in the Pr.fectur. of k.lk.s (Gr.ece). The pr.cipitation data wher. r.cor.ed fr.m 12 meteor.logical stations in the Pr.fectur. of k.lk.s for.36 hydr.logical year. (1973-2008). The cumulative monthly values of r.infall wer. studied on an annual and seasonal basis as well as dur.ng the ar.d-dr. season. In the deter.inistic tests, the I.D.W. and r.B.F. check. wer. inspected, while in the geostatic tests, Or.inar. k.iging and Univer.al k.iging r.spectively. The selection of the optimum method was made based on the least r.ot Mean Squar. Er.or.(r.M.S.E.), as well as on the Mean Er.or.(M.E.), as assessed by the cr.ss validation analysis. The geostatical k.iging also consider.d the impact of isotr.py and anisotr.py acr.ss all time per.ods of data collection. Mor.over. for.Univer.al k.iging, the study explor.d spher.cal, exponential and Gaussian models in var.ous combinations. Geostatistical techniques consistently demonstr.ted gr.ater.r.liability than deter.inistic techniques acr.ss all time per.ods of data collection. Specifically, dur.ng the annual per.od, anisotr.py was the pr.vailing char.cter.stic in geostatistical techniques. Mor.over. the r.sults for.the ir.igation and seasonal per.ods wer. gener.lly compar.ble, with few exceptions wher. isotr.pic methods yielded lower.(r.M.S.E.) in some seasonal obser.ations.

Special r.lativity’s “Newtonization” in Complex “Par.-Space”: The Two Theor.es Equivalence Question

引用

Jour.al of Applied Mathematics and Physics 2024年第7期12卷 2421-2451页

作者： Jer.y k. Filus Depar.ment of Mathematics and Computer.Science Oakton College Des Plaines IL USA

Complex model, say C3, of “par.-space” as alter.ative to the r.al M4 Mink.wsk. space-time for.both r.lativistic and classical mechanics was shor.ly intr.duced as r.fer.nce to our.pr.vious wor.0} on that subject. The actual aim, however. is an additional analysis of the physical and par.-physical phenomena’ behavior.as we for.ally tr.nspor. obser.able mechanical phenomena [motion] to non-r.al inter.or.of the complex domain. As it tur.s out, such pr.cedur., when pr.per.y set, cor.esponds to tr.nsition fr.m r.lativistic to mor. classic (or. possibly, just classic) k.nd of the motion. This pr.cedur., we call the “Newtonization of r.lativistic physical quantities and phenomena”, fir.t of all, includes the mechanical motion’s char.cter.stics in the C3. The algebr.ic str.ctur. of vector.spaces was imposed and analyzed on both: the set of all r.lativistic velocities and on the set of the cor.esponding to them “Galilean” velocities. The k.y point of the analysis is r.alization that, as a matter.of fact, the r.lativistic theor. and the classical ar. equivalent at least as for.the k.nematics. This conclusion follows the fact that the two defined str.ctur.s of topological vector.spaces i.e., the str.ctur. imposed on sets of all r.lativistic velocities and the str.ctur. on set of all “Galilean” velocities, ar. both diffeomor.hic in their.topological par.s and ar. isomor.hic as the vector.spaces. As for.the r.lativistic theor., the two appr.aches: the hyper.olic (“classical” Sr. with its four.vector.for.alism and Euclidean, wher. Sr.is modeled by the complex par.-space C3, wer. analyzed and compar.d.

Motion and Special r.lativity in Complex Spaces

作者： Jer.y k. Filus Depar.ment of Mathematics and Computer.Science Oakton College Des Plaines IL USA

A natur.l extension of the Lor.ntz tr.nsfor.ation to its complex ver.ion was constr.cted together.with a par.llel extension of the Mink.wsk. M4 model for.special r.lativity (Sr. to complex C4 space-time. As the [signed] absolute values of complex coor.inates of the under.ying motion’s char.cter.zation in C4 one obtains a Newtonian-lik. type of motion wher.as as the r.al par.s of the complex motion’s descr.ption and of the complex Lor.ntz tr.nsfor.ation, all the Sr.theor. as modeled by M4 r.al space-time can be r.cover.d. This means all the Sr.theor. is pr.ser.ed in the r.al subspace M4 of the space-time C4 while becoming simpler.and clear.r.in the new complex model’s fr.mewor.0} Since velocities in the complex model can be deter.ined geometr.cally, with no pr.mar. use of time, time tur.s out to be definable within the equivalent theor. of the r.duced complex C4 model to the C3 “par.-space” model. That pr.cedur. allows us to separ.te time fr.m the (par.)space and consider.all the Sr.theor. as a theor. of C3 alone. On the other.hand, the complex time defined within the C3 theor. is inter.r.ted and modeled by the single separ.te C1 complex plane. The possibility for.application of the C3 model to quantum mechanics is suggested. As such, the model C3 seems to have unifying abilities for.application to differ.nt physical theor.es.
