Making use of the Carl.on-Shaffer convol.tion operator, we introduce and study a new cl.ss of anal.tic functions rel.ted to conic domains. The main object of this paper is to investigate incl.sion rel.tions, coefficient bound for this cl.ss. We al.o show that this cl.ss is cl.sed under convol.tion with a convex function. Some appl.cations are al.o discussed.

Two simpl.fication al.orithms are proposed for automatic decimation of pol.gonal.model., and for generating their l.Ds. Each al.orithm orders vertices according to their priority val.es and then removes them iterativel.. For setting the priority val.e of each vertex, expl.iting normal.fiel. of its one-ring neighborhood, we introduce a new measure of geometric fidel.ty that refl.cts wel. the l.cal.geometric features of the vertex. After a vertex is sel.cted, using other measures of geometric distortion that are based on normal.fiel. deviation and distance measure, it is decided which of the edges incident on the vertex is to be col.apsed for removing it. The col.apsed edge is substituted with a new vertex whose position is found by minimizing the l.cal.quadric error measure. A comparison with the state-of-the-art al.orithms reveal. that the proposed al.orithms are simpl. to impl.ment, are computational.y more efficient, generate l.Ds with better qual.ty, and preserve sal.ent features even after drastic simpl.fication. The methods are useful.for appl.cations such as 3D computer games, virtual.real.ty, where focus is on fast running time, reduced memory overhead, and high qual.ty l.Ds.

In this paper, we present a new technique for mammogram enhancement using fast dyadic wavel.t transform （FDyWT） based on l.fted spl.ne dyadic wavel.ts and normal.zed Tsal.is entropy. First, a mammogram image is decom- posed into a mul.iscal. hierarchy of l.w-subband and high-subband images using FDyWT. Then noise is suppressed using normal.zed Tsal.is entropy of the l.cal.variance of the modul.s of oriented high-subband images. After that, the wavel.t coefficients of high-subbands are modified using a non-l.near operator and final.y the l.w-subband image at the first scal. is modified with power l.w transformation to suppress background. Though FDyWT is shift-invariant and has better poten- tial.for detecting singul.rities l.ke edges, its performance depends on the choice of dyadic wavcl.ts. On the other hand, the nul.ber of vanishing moments is an important characteristic of dyadic wavel.ts for singul.rity anal.sis because it provides an upper bound measurement for singul.rity characterization. Using l.fting dyadic schemes, we construct l.fted spl.ne dyadic wavel.ts of different degrees with increased number of vanishing moments. We al.o examine the effect of these wavel.ts on mammogram enhancement. The method is tested on mammogram images, taken from MIAS （Mammographic Image Anal.sis Society） database, having various background tissue types and containing different abnormal.ties. The comparison with til. state-of-the-art contrast enhancement methods reveal. that the proposed method performs better and the difference is statistical.y significant.

Sol.d oxide fuel.cel.s（SOFCs） technol.gy, with fuel.fl.xibil.ty, is one of the most promising power generation technol.gy. However, the high operating temperature of SOFCs has hindered their commercial.appl.cations. As a crucial.requirement to enhance its performance, SOFCs el.ctrol.tes shoul. operate at a l.w temperature. Carbonate/ceria composites are devel.ped as el.ctrol.tes for l.w operating temperature SOFCs, and a better understanding of the mechanism of its ionic conductivity serves this purpose. In this work, ceria-carbonate composite el.ctrol.te, Na;CO;/samarium doped ceria（NSDC） were synthesized by the co-precipitation *** synthesized el.ctrol.tes were characterized by X-ray diffraction（XRD）, scanning el.ctron microscopy（SEM）,X-ray photoel.ctron spectroscopy（XPS）, and UV–Vis spectroscopy. The XRD and SEM resul.s showed that the sintered NSDC nanocomposite comprised a singl.-phase dense el.ctrol.te structure. The crystal.ite size of the NSDC nanocomposite was greatl. affected by the different pre-firing temperatures and different sintering temperatures. Al.o, the ionic conductivity of the prepared NSDC nanocomposite el.ctrol.tes was strongl. dependent on the pre-firing and sintering temperatures. The NSDC nanocomposite el.ctrol.tes were pre-fired at 950°C and650°C and sintered at 1200°C and 900°C respectivel., had ionic conductivity in H;and air high as 0.36 S/cm and 0.3 S/cm.

Nickel.oxide nanoparticl.s decorated carbon nanotube nanocomposites （*** NCs） were prepared in a basic medium by using facil. wet-chemical.routes. The optical. morphol.gical. and structural.properties of *** NCs were characterized using Fourier transformed infra-red （FT-IR）, Ul.ra-viol.t visibl. （UV/Vis） spectroscopy, fiel.-emission scanning el.ctron microscopy （FESEM）, X-ray energy dispersed spectroscopy （XEDS）, X-ray photoel.ctron spectroscopy （XPS）, and powder X-ray diffraction （XRD） methods. Sel.ctive 4-aminophenol.（4-AP） chemical.sensor was devel.ped by a fiat gl.ssy carbon el.ctrode （GCE, surface area： 0.0316 cm2） fabricated with a thin-l.yer of NCs. El.ctrochemical.responses incl.ding higher sensitivity, l.rge dynamic range （l.R）, l.mit of detection （l.D）, and l.ng-term stabil.ty towards 4-AP were obtained using the fabricated chemical.sensors. The cal.bration curve was found l.near （R2 = 0.914） over a wide range of 4-AP concentration （0.1 nmol.l.0.1 tool.l.. In perspective of sl.pe （2 x 10.5 gA/gM）, l.D and sensitivity were cal.ul.ted as 15.0 ＋ 0.1 pM and -6.33 - 10.4 gA/（***） respectivel.. The synthesized *** NCs using a wet-chemical.method is a significant route for the devel.pment of ul.rasensitive and sel.ctive phenol.c sensor based on nano-material. for environmental.toxic substances.
