This paper discusses a critical study of fault detection.an. fault time an.lysis in.a Un.fied Power Flow Con.roller (UPFC) tran.mission.lin.. Here the Discrete Wavelet Tran.form (DWT) an. Discrete Fourier Tran.form (DFT) approach are used for processin. the faulty curren. sign.l to obtain.fun.amen.al curren. sign.l. The extracted fault curren. sign.ls from the curren. tran.former are fed to DWT an. DFT approach for computin. spectral en.rgy (SE). The differen.ial spectral en.rgy (DSE) of phase curren.s are evaluated by takin. the differen.e of SE obtain.d at sen.in. an. receivin. en.. The DSE is the key factor for decidin. the fault in.an. of the phase or n.t. The Daubechy mother wavelet (db4) is used here because of its high accuracy of detection.with less processin. time. The n.velty of the scheme is that it can.accurately detect the critical fault variation.of the lin.. n.mber of simulation. are validated at the extreme con.ition.of the lin. an. compared to other con.en.ion.l existin. scheme. Multi-phase fault in.double circuit lin., CT saturation. UPFC operatin. con.ition.(series voltage an. an.le), UPFC location.an. win. speed variation.in.ludin. win. farm simulation.are validated to verify the performan.e of the scheme. The advan.ages of the scheme is that it works effectively to detect the fault at an. stage of critical con.ition.of the lin. an. fault detection.time remain. within.20 msec (less than.on. cycle period). This scheme protects both in.ern.l an. extern.l zon. in.ludin. parameter variation.of the lin..

This study reports the n.trogen.uptake rate （usin. 15n.tracer） of phytoplan.ton.in.surface waters of differen. fron.al zon.s in.the In.ian.sector of the Southern.Ocean.（SO） durin. austral summer of 2013. The in.estigated area en.ompasses four major fron.al systems, i.e., the subtropical fron. （STF）, suban.arctic fron. （SAF）, polar fron.-1 （PF1） an. polar fron.-2 （PF2）. Southward decrease of surface water temperature was observed, whereas surface salin.ty did n.t show an. sign.fican. tren.. n.trien. （n.3- an. SiO44-） con.en.ration. in.reased southward from STF to PF; while ammon.um （n.4＋）, n.trite （n.2-） an. phosphate （PO433 remain.d compara- tively stable. An.lysis of n.trien. ratios in.icated poten.ial n.limited con.ition. at the STF an. SAF but n. such scen.rio was observed for PF. In.terms of phytoplan.ton.biomass, PF1 was foun. to be the most productive followed by SAF, whereas PF2 was the least productive region. n.trate uptake rate in.reased with in.reasin. latitude, as n. systematic spatial variation.was discern.d for n.4＋ an. urea （CO（n.2）2）. Lin.ar relation.hip between.n.trate an. total n.uptake reveals that the studied area is capable of exportin. up to 60% of the total production.to the deep ocean.if the en.iron.en.al settin.s are favorable. Like n.uptake rates the f-ratio also in.reased towards PF region.in.icatin. comparatively higher n.w production.in.the PF than.in.the subtropics. The moderately high averagefiratio （0.53） in.icates poten.ially n.ar equal con.ribution. by n.w production.an. regen.rated production.to the total productivity in.the study area. Elevation.in.n.uptake rates with declin.n. temperature suggests that the SO with its vast quan.ity of cool water could play an.importan. role in.drawin. down.the atmospheric CO2 through the ＂solubility pump＂.

Lacustrin. sedimen. preserves high-resolution.biogeochemical records of past variation. in.watershed processes con.rollin. lake sedimen.ation. The curren. study explores historical variation. in.autochthon.us an. allochthon.us sedimen. supplies to a large tropical freshwater lake system(Upper Lake, Bhopal) protected un.er the in.ern.tion.l Ramsar Con.en.ion.of 2002 again.t an.hropogen.c pressures. For this purpose, multi-proxy biogeochemical data are presen.ed for organ.c matter(total organ.c carbon. total n.trogen. phosphorous, an. loss on.ign.tion.[LOI] at550°C), carbon.te(LOI at 950°C), lithic sedimen.(alumin.m, titan.um, iron. calcium, magn.sium,sodium, potassium, man.an.se, zircon.um, n.obium, hafn.um, tan.alum, thorium, uran.um, an. rare earth elemen.s), an. an.hropogen.c in.uts(lead) measured in.a 38 cm lon. sedimen. core retrieved from the lake. In.addition.to the lacustrin. sedimen. core, the samples of catchmen. bedrock, surface soils, major stream sedimen., an. eolian.dust collected from the lake periphery also are an.lyzed. The systematic biogeochemical excursion. in.the upper core section.top ～8 cm) in.icate in.reased an.hropogen.c in.uts, watershed den.dation.by agricultural activities, artificially reduced fluvial sedimen. supply, relatively in.reased dust in.uts an. lake eutrophication.in.the last few decades. The curren. study un.erscores the roles of an.hropogen.c lan.-use an. wetlan. con.ervation.practices in.the rapid alteration.of autochthon.us an. allochthon.us sedimen. supplies to open.aquatic ecosystems. Further, risin. lake eutrophication.levels despite a man.ged reduction.in.allochthon.us sedimen. supplies seem challen.in. to con.rol due to dissolved n.trien. supply from urban.sewage discharge an. run.ff from agricultural lan. in.the watershed.

Static an. dyn.mic properties of both complemen.ary n.Ge/p-Si an. p-Ge/n.Si hetero-jun.tion.DoubleDrift IMPATT diodes have been.in.estigated by an.advan.ed an. realistic computer simulation.techn.que, devel- oped by the authors, for operation.in.the Ka-, V- an. W-ban. frequen.ies. The results are further compared with correspon.in. Si an. Ge homo-jun.tion.devices. The study shows high values of device efficien.y, such as 23%, 22% an. 21.5%, for n.Ge/p-Si IMPATTs at the Ka, V an. W ban.s, respectively. The peak device n.gative con. ductan.es for n.Si/p-Ge an. n.Ge/p-Si hetero-jun.tion.devices foun. to be 50.7× 10^6 S/m^2 an. 71.3× 106 S/m^2, which are -3-4 times better than.their Si an. Ge coun.erparts at the V-ban.. The computed values of RF powerden.ity for n.Ge/p-Si hetero-jun.tion.IMPATTs are 1.0 ×10^9, 1.1 × 10^9 an. 1.4× 10^9 W/m^2, respectively, for Ka-, V- an. W-ban. operation. which can.be observed to be the highest when.compared with Si, Ge an. n.Si/p-Ge devices. Both of the hetero-jun.tion., especially the n.Ge/p-Si hetero-jun.tion.diode, can.thus become a superior RF-power gen.rator over a wide ran.e of frequen.ies. The presen. study will help the device en.in.ers to choose a suitable material pair for the developmen. of high-power MM-wave IMPATT for application. in.the civil an. defen.e-related aren..

This gen.ralizes the sequen.e space m(φ) in.roduced an. studied by Sargen.[10]. We study some of its properties like solidity, completen.ss, an. obtain.some in.lusion.results. We also characterize the multiplier problem an. obtain.the correspon.in. spaces dual to m(E k , φ, Λ). We prove some gen.ral results too.
