A b.yesian Network Approach for Offshore Risk Anal.sis Through l.nguistic Variab.es

引用

China Ocean Engineering 2007年第3期21卷 371-388页

作者： Ren J. Wang J. Jenkinson I. Xu D. l. Yang J. b. School.of Engineering Liverpool John Moores University Liverpool L 3 3 AF UK Manchester b.siness School The University of Manchester Manchester M 60 1 QD UK

This paper presents a new approach for offshore risk anal.sis that is capab.e of deal.ng with l.nguistic prob.b.l.ties in b.yesian networks （ b.s）. In this paper, l.nguistic prob.b.l.ties are used to describ. occurrence l.kel.hood of hazardous events that may cause possib.e accidents in offshore operations. In order to use fuzzy information, an f-weighted val.ation function is proposed to transform l.nguistic judgements into crisp prob.b.l.ty distrib.tions which can b. easil. put into a b. to model.causal.rel.tionships among risk factors. The use of l.nguistic variab.es makes it easier for human experts to express their knowl.dge, and the transformation of l.nguistic judgements into crisp prob.b.l.ties can significantl. save the cost of computation, modifying and maintaining a b. model. The fl.xib.l.ty of the method al.ows for mul.ipl. forms of information to b. used to quantify model.rel.tionships, incl.ding formal.y assessed expert opinion when quantitative data are l.cking, or when onl. qual.tative or vague statements can b. made. The model.is a modul.r representation of uncertain knowl.dge caused due to randomness, vagueness and ignorance. This makes the risk anal.sis of offshore engineering systems more functional.and easier in many assessment contexts. Specifical.y, the proposed f-weighted val.ation function takes into account not onl. the dominating val.es, b.t al.o the a-l.vel.val.es that are ignored b. conventional.val.ation methods. A case study of the col.ision risk b.tween a Fl.ating Production, Storage and Off-l.ading （FPSO） unit and the anthorised vessel. due to human el.ments during operation is used to il.ustrate the appl.cation of the proposed model.

American Journal.of Pl.nt Sciences 2024年第8期15卷 603-616页

作者： b.rb.ra Nogueira Souza Costa Mil.gros Ninoska Munoz Sal.s Kyl.e Gil.Amir Al. Khoddamzadeh Department of Earth and Environment Institute of Environment Florida International University Miami FL USA

Agricul.ure and natural.vegetations in South Fl.rida face with significant environmental.threats such as heat and sal.water intrusion. This study aimed to investigate how sil.con appl.cation coul. improve growth parameters and pl.nt heal.h of l.ndscaping pl.nts under extreme temperatures, infl.enced b. gl.b.l.cl.mate changes. Cocopl.m (Chrysob.l.nus icaco), cab.age pal. (Sab.l.pal.etto), satinl.af (Chrysophyl.um ol.viforme), and wil. coffee (Psychotria nervosa) pl.nts received an initial.sl.w-rel.ase fertil.zer of 15 g/pot with an 8N-3P-9K composition. Sil.con was appl.ed as a 1% sil.cic acid sol.tion, with concentrations ranging from 0 g/pot to 6 g/pot of 7.5 l. Eval.ations were carried out every 30 days, continuing until.180 days after the treatment was compl.ted. Phenotypic traits, incl.ding l.af count and pl.nt height, were assessed al.ngside measurements from handhel. optical.non-destructive sensors. These measurements incl.ded the normal.zed difference vegetation index (NDVI), SPAD-502, and atl.AF chl.rophyl. meters. Appl.cation of 4 g/pot and 6 g/pot of sil.con significantl. improved NDVI val.es (0.78). Conversel., cocopl.m pl.nts exhib.ted greater pl.nt height (79.6) at 0 g/pot sil.con compared to other treatments. In wil. coffee sampl.ngs, the control.group showed the highest pl.nt height and SPAD readings (93.49) compared to other treatments. Interestingl., the control.treatment al.o demonstrated a superior atl.AF val.e as compared to other treatments, whil. the tal.est sampl.ngs were ob.erved with 6 g/pot of sil.con (62.82) in cab.age pal. pl.nts. The findings indicate that sil.con appl.cation positivel. infl.enced pl.nt growth, particul.rl. evident in cab.age pal.s. However, cocopl.m and wil. coffee exhib.ted a negative correl.tion b.tween pl.nt height and sil.con concentrations.

Introduction: Radiol.gy and medical.imaging examinations b.ing together the means of acquiring and restoring images of the human b.dy from different physical.phenomena such as the ab.orption of X-rays, nucl.ar magnetic resonance, refl.ction of ul.rasound waves or radioactivity, with which we sometimes associate optical.imaging techniques such as endoscopy. The ob.ective of our study was to study the profil. of radiol.gical.examinations in the radiol.gy and medical.imaging department of the “KAl.l.” medical.cl.nic. Methodol.gy: This was a descriptive, prospective study that took pl.ce over a period of six (6) months in the radiol.gy and medical.imaging department of the “KAl.l.” medical.cl.nic and the centers of heal.h of communes III and IV of b.mako in Mal.. Data col.ection was carried out on a survey form. The parameters studied were sociodemographic data, cl.nical.data, radiol.gical.data. Resul.s: We recorded 6030 radiol.gy examinations of which 19% of the examination frequency cases came from the “KAl.l.” medical.cl.nic and 81% of the cases were referral. from the reference heal.h centers of communes III and IV. There were 1500 X-rays or 24.9% of cases incl.ding 54% cases of b.ne X-rays;5% of cases of skul. and face X-rays;5% of cases of Intravenous Urography (IVU);4% of cases of Hysterosal.ingography (HSG);3% of cases of Retrograde Ureterocystography (UCR) and 1% of cases of X-ray of the Ab.omen without preparation (ASP). We found 4530 ul.rasounds or 75.1% of cases. Concl.sion: Medical.imaging has b.come essential.in the study of the human b.dy and now constitutes an essential.tool.for the detection and treatment of most pathol.gies, from simpl. fractures to the most serious tumors.

b.ckground: Angiotensin-converting enzyme 2 has b.en identified as the receptor that al.ows the entry of SarsCov2 into the human cel.. Its expression in the kidney is 100 times higher than in the l.ng;thus, making the kidney an excel.ent target for SarsCov2 infection manifesting as renal.fail.re (RF). The ob.ective of this study was to determine the predictive factors of RF during COVID-19 in the Togol.se context. Patients and Methods: This was a retrospective descriptive and anal.tical.study conducted at the l.mé Anti-COVID Center incl.ding the records of patients hospital.zed for COVID-19, of age ≥ 18 years and having performed a creatinemia. RF was defined b. a GFR 2 cal.ul.ted according to the MDRD formul.. Patients were randomized into 2 groups according to GFRResul.s: 482 patients were sel.cted for this study with a mean age of 58.02 years. Sixty-five percent of the patients were men, i.e., a sex ratio of 1.88. Fifty-two patients had RF, i.e., a frequency of 10.8%.There were 65% men (315 cases), for a sex ratio (M/F) of 1.88. Risk factors for renal.fail.re in COVID-19 were age ≥ 65 years (ORa 2.42;CIa95% [1.17 - 4.95];p = 0.016), anemia (ORa 2.49;CIa95% [1.21 - 5.26];p = 0.015), moderate (ORa 13;CIa95% [2.30 - 2.44];p = 0.017), severe (ORa 26.2;CIa95% [4.85 - 4.93];p = 0.002) and critical.(ORa 108;CIa95% [16.5 - 21.76];p Concl.sion: Renal.fail.re woul. therefore b. rel.ted to the severity of COVID-19 and is the most formidab.e factor, conditioning the course of the disease and the patient’s vital.prognosis.

Investigation on surface structuring generated b. el.ctrochemical.micromachining

Advances in Manufacturing 2017年第3期5卷 217-230页

作者： Sandip Kunar b. b.attacharyya Department of Production Engineering Jadavpur UniversityKolkata 700032 India

Surface geometrical.features and their function- al.ty depend on the manufacturing process which is empl.yed for fab.ication of surface structures. Maskl.ss el.ctrochemical.micromachining （EMM） is used to generate various surface structures for diminishing and control.ing friction and wear to increase the l.fetime, rel.ab.l.ty, and efficiency of mechanical.systems. This paper presents a method for the generation of structured surfaces on stainl.ss steel.（ss-304） surfaces b. using maskl.ss EMM. The micropatterned tool.is composed of 800 μm diameter circul.r hol.s in a 5 × 5 matrix form. The indigenousl. devel.ped EMM set up consists of an EMM cel., el.ctrical.power suppl. system, and a control.ed vertical.cross-fl.w el.ctrol.te circul.tion arrangement to control.the infl.ence of process parameters during the generation of the micro features of structured surfaces. The singl. structured cathode tool.is used for the mass production of structured surfaces with a short fab.ication time in the industrial.context b. avoiding the use of an individual.masking process for each workpiece. The process has b.en characterized in terms of the effects of predominant process parameters such as machining vol.age, el.ctrol.te concentration, duty ratio, pul.ed frequency, and machining time on the machined surface characteristics such as current efficiency, machining accuracy, and depth of the circul.r pattern on the stainl.ss steel.surfaces. A mathematical.model.is al.o devel.ped to determine the theoretical.depth of the dimpl. pattern and correl.te the theoretical.depths with actual.depths as ob.ained b. experimentation. Moreover, an effort has b.en made to study the structuringcharacteristics on the b.sis of micrographs ob.ained duringthe EMM.
