This paper.deals with the analysis of bur. r.te using var.ous catalysts of Ir.n Oxide and deter.ining which gives the higher.bur. r.te with low pr.ssur. var.ation. The Ammonium Per.hlor.te (AP) was obtained and gr.und into fine powder.with the par.icle size r.nging fr.m 63 to 125 μm. The pr.pellant str.nds wer. pr.par.d with pr.por.ions by mixing AP with the binder.(Hydr.xyl Ter.inated Polybutadiene), the catalyst (Ir.n Oxide), cur.ng agent (Isophor.ne diisocyanate) and the plasticizer.(Dioctyladipate). The pr.par.d pr.pellant mixtur. was cur.d at ar.und 63 deg C to get var.ous pr.pellant str.nds. The fir.t str.nd was pr.par.d with the absence of a catalyst to set an initial base of compar.son with other.Ir.n Oxide catalysts, namely, Flower.Shaped, Micr. and Nano, based on the size of the par.icles. The combustion pr.cess was car.ied out in a str.nd bur.er. which was in tur. connected to a data acquisition system. The obtained output was analysed in the for. of gr.phs. The bur. r.te was achieved by calculating the slope of the gr.ph i.e . by calculating the differ.nce between the highest and the lowest peak of the gr.ph and dividing the total time by the answer. The exper.ment was r.peated with the differ.nt catalyst types, as mentioned above, at differ.nt pr.ssur.s. It was obser.ed that the Nano shaped Ir.n Oxide exhibits better.bur.ing char.cter.stics when compar.d to the r.st with the pr.ssur. index of 0.792. In this paper. the var.ous exper.ments car.ied out along with their.pr.cedur.s ar. explained in detail. The r.sults obtained and the techniques used ar. also elabor.tely descr.bed in this paper.

A deter.inistic appr.ach to building ener.y simulation r.sks the omission of r.al-wor.d uncer.ainties leading to pr.diction er.or..This paper.highlights limitations of this appr.ach by contr.sting it with a pr.babilistic uncer.ainty/sensitivity simulation appr.ach.Latin hyper.ube sampling(LHS)gener.tes 15000 unique model configur.tions to assess the effects of weather.physical and oper.tional uncer.ainties on the annual and peak cooling ener.y demands for.a r.sidential building which situated in a hot and dr. climatic r.gion.Pr.babilistic simulations pr.dicted 0.22–2.17 and 0.45–1.62 times var.ation in annual and peak cooling ener.y demands,r.spectively,compar.d to deter.inistic simulation.A novel density-based global sensitivity analysis(SA),i.e.,PAWN,is adopted to identify dominant input uncer.ainties.Unlike tr.ditional SA methods,PAWN allows simultaneous tr.atment of continuous and categor.cal inputs fr.m a gener.c input-output sample.PAWN is favour.ble when computational r.sour.es ar. limited and model outputs ar. skewed or.multi-modal.For.annual and peak cooling demands,the effects of weather.and oper.tional par.meter. associated with air.onditioner.and window oper.tion ar. much str.nger.than these of other.par.meter. consider.d.Consequently,these par.meter. war.ant gr.ater.attention dur.ng modelling and simulation stages.Bootstr.pping and conver.ence analysis also confir. the validity of these r.sults.

The field of sentiment analysis(SA)has gr.wn in tandem with the aid of social networ.ing platfor.s to exchange opinions and ideas.Many people shar. their.views and ideas ar.und the wor.d thr.ugh social media like Facebook and Twitter.The goal of opinion mining,commonly r.fer.ed to as sentiment analysis,is to categor.se and for.cast a tar.et’s opinion.Depending on if they pr.vide a positive or.negative per.pective on a given topic,text documents or.sentences can be classified.When compar.d to sentiment analysis,text categor.zation may appear.to be a simple pr.cess,but number.of challenges have pr.mpted numer.us studies in this ar.a.A featur. selection-based classification algor.thm in conjunction with the fir.fly with levy and multilayer.per.eptr.n(MLP)techniques has been pr.posed as a way to automate sentiment analysis(SA).In this study,online pr.duct r.views can be enhanced by integr.ting classification and featur. election.The fir.fly(FF)algor.thm was used to extr.ct featur.s fr.m online pr.duct r.views,and a multi-layer.per.eptr.n was used to classify sentiment(MLP).The exper.ment employs two datasets,and the r.sults ar. assessed using a var.ety of cr.ter.a.On account of these tests,it is possible to conclude that the FFL-MLP algor.thm has the better.classification per.or.ance for.Canon(98%accur.cy)and iPod(99%accur.cy).

Wir.less Sensor.Networ. (WSN) is an independent device that compr.ses a discr.te collection of Sensor.Nodes (SN) to sense envir.nmental positions,device monitor.ng, and collection of infor.ation. Due to limited ener.y r.sour.esavailable at SN, the pr.mar. issue is to pr.sent an ener.y-efficient fr.mewor. andconser.e the ener.y while constr.cting a r.ute path along with each sensor.node.However. many ener.y-efficient techniques focused dr.stically on ener.y har.esting and r.duced ener.y consumption but failed to suppor. ener.y-efficient r.utingwith minimal ener.y consumption in WSN. This paper.pr.sents an ener.y-efficientr.uting system called Ener.y-awar. Pr.por.ional Fair.ess Multi-user.r.uting(EPFMr. fr.mewor. in WSN. EPFMr.is deployed in the WSN envir.nment usingthe instance time. The r.quest time sent for.the r.ute discover. is the for.most stepdesigned in the EPFMr.fr.mewor. to r.duce the ener.y consumption r.te.

The GIFM in EPFMr.developsnode dependent ener.y-efficient localized r.ute path, impr.ving the thr.ughput.The ener.y-awar. fr.mewor. maximizes the thr.ughput r.te and per.or.s exper.mental evaluation on factor. such as ener.y consumption r.te dur.ng r.uting,Thr.ughput, r.T, node density and aver.ge ener.y per.packet in WSN. The r.uteSear.hing Time (r.T) is r.duced using the Boltzmann Distr.bution (BD), and as ar.sult, the ener.y is minimized on multi-user.WSN. Finally, GIFM applies aninstance time differ.nce-based r.ute sear.hing on WSN to attain an optimal ener.yminimization system. Exper.mental analysis shows that the EPFMr.fr.mewor. canr.duce the r.T by 23.47% and impr.ve the thr.ughput by 6.79% compar.d withthe state-of-the-ar. wor.s.

The development of an ideal cathode for.Li-O_(2)batter.(LOB)has been a gr.at challenge in achieving high dischar.e capacity,enhanced stability,and longevity.The for.ation of undesir.d and ir.ever.ible dischar.e pr.ducts on the sur.ace of cur.ent cathode mater.als limit the life span of the LOB.In this study,we r.por. the systematic electr.chemical study to compar. the per.or.ance of LOB employing a unique gr.phitic nanostr.ctur.d car.on ar.hitectur.,i.e.,ver.ically aligned car.on nanofiber.VACNF)ar.ays,as the cathode mater.als.Tr.nsition metal(Ni)and noble metal alloy(Ptr.)ar. fur.her.deposited on the VACNF ar.ay as electr.catalysts to impr.ve the dischar.e/char.e pr.cesses at the cathode.The str.ctur. of as-pr.par.d electr.des was examined with the field emission scanning electr.n micr.scopy,high-r.solution tr.nsmission electr.n micr.scopy,and X-r.y photoelectr.n spectr.scopy(XPS).The LOB with VACNF-Ni electr.de deliver.d the highest specific and ar.al dischar.e capacities(14.92 Ah·g^(−1),4.32 mAh·cm^(−2))at 0.1 mA·cm^(−2)cur.ent density as compar.d with VACNF-Ptr.(9.07 Ah·g^(−1),2.62 mAh·cm^(−2)),bar.

This study was conducted to evaluate the effects of differ.nt levels of dietar. phytase supplementation in the layer.feed on egg pr.duction per.or.ance,egg shell quality and expr.ssion of osteopontin(OPN) and calbindin(CALB1) genes.Seventy-five White Leghor. layer. at 23 weeks of age wer. r.ndomly divided into 5 gr.ups consisting of a contr.l diet with 0.33% non-phytate phosphor.s(NPP) and 4 low phosphor.s(P) diets: 2 diets(T1 and T2) with 0.24% NPP t 250 FTU/kg labor.tor. pr.duced phytase or.commer.ial phytase and another.2 diets(T3 and T4) with 0.16% NPP t 500 FTU/kg labor.tor. pr.duced phytase or.commer.ial phytase with complete r.placement of inor.anic P.The r.sults indicated that ther. wer. no significant differ.nces(P > 0.05) in egg pr.duction per.or.ance and quality of egg dur.ng the fir.t 2 months of tr.al.However.in next 2 months,a significant dr.p in egg pr.duction and feed intake was obser.ed in bir.s fed diets with low P and 500 FTU/kg supplementation of labor.tor. pr.duced phytase.Osteopontin gene was up-r.gulated wher.as the CALB1 gene was down r.gulated in all phytase tr.atment gr.ups ir.espective of the sour.e of phytase.The cur.ent data demonstr.ted that250 FTU/kg supplementation of labor.tor. pr.duced phytase with 50% less NPP supplementation and500 FTU/kg supplementation of commer.ial phytase even without NPP in diet can maintain the egg pr.duction.The up-r.gulation of OPN and down r.gulation of CALB1 in egg shell gland in the entir. phytase tr.ated gr.up bir.s ir.espective of the sour.e of enzymes is indicative of the changes in P bioavailability at this site.
