Increa.es in wildfire a.tivity in the western United Sta.es ha.e prompted la.d ma.a.ers to reeva.ua.e ma.a.ement pra.tices. In the Colora.o Front Ra.ge, where popula.ion density is high, there is often a.grea. concern rega.ding wildfire which lea.s to efforts tha. will reduce fire ha.a.d. The most common method of a.hieving this goa. is to thin the forest of sma.l dia.eter trees. Oftentimes these pra.tices a.e underta.en with little knowledge of the ecologica. consequences of such trea.ments. We investiga.ed the effect(s) of three trea.ments (control, thinning-only a.d broa.ca.t chipping) on tra.e ga. fluxes (CO2, CH4, a.d N2O), litter ma.s, a.d soil ca.bon a.d nitrogen. In a.sma.l plot study, we used a.2 × 3 × 3 ra.domized complete block design to determine the influence of nutrient a.endments (woodchips, nitrogen, a.d phosphorus a.a.la.ility) on tra.e ga. fluxes. The sta.d-ma.a.ement study revea.ed tha. neither thinning-only nor broa.ca.t chipping significa.tly a.fected soil ca.bon or nitrogen, while thinning-only significa.tly reduced the a.ount of forest floor litter. Ea.h tra.e ga. flux wa. significa.tly a.fected by the da.e of sa.pling (June or a.gust). CO2 a.d N2O fluxes ea.h ha. a.significa.t intera.tion between trea.ment a.d sa.pling da.e. We a.tribute this to a.difference in moisture a.a.la.ility between the sa.pling times. In the plot study we found tha. only the intera.tion between woodchip a.dition a.d phosphorus a.a.la.ility significa.tly a.fected CO2 flux. Nitrous oxide fluxes were not significa.tly a.fected by a.y combina.ion, however, metha.e upta.e wa. found to respond significa.tly to different nitrogen a.d phosphorus levels.

Dispa.ity estima.ion is a. ill-posed problem in computer vision. It is explored comprehensively due to its usefulness in ma.y a.ea. like 3D scene reconstruction, robot na.iga.ion, pa.ts inspection, virtua. rea.ity a.d ima.e-ba.ed rendering. In this pa.er, we propose a.hybrid dispa.ity genera.ion a.gorithm which uses census ba.ed a.d segmenta.ion ba.ed a.proa.hes. Census tra.sform does not give good results in textureless a.ea., but is suita.le for highly textured regions. While segment ba.ed stereo ma.ching techniques gives good result in textureless regions. Coa.se dispa.ities obta.ned from census tra.sform a.e combined with the region informa.ion extra.ted by mea. shift segmenta.ion method, so tha. a.region ma.ching ca. be a.plied by using a.fine tra.sforma.ion. a.fine tra.sforma.ion is used to remove noise from ea.h segment. Mea. shift segmenta.ion technique crea.es more tha. one segment of sa.e object resulting into non-smoothness dispa.ity. Region merging is a.plied to obta.n refined smooth dispa.ity ma.. Fina.ly, multila.era. filtering is a.plied on the dispa.ity ma. estima.ed to preserve the informa.ion a.d to smooth the dispa.ity ma.. The proposed a.gorithm genera.es good results compa.ed to the cla.sic census tra.sform. Our proposed a.gorithm solves sta.da.d problems like occlusions, repetitive pa.terns, textureless regions, perspective distortion, specula. reflection a.d noise. Experiments a.e performed on middlebury stereo test bed a.d the results demonstra.e tha. the proposed a.gorithm a.hieves high a.cura.y, efficiency a.d robustness.

a.uminium ba.ed composites conta.ning 1, 1.5 a.d 2wt. % of na.o-sized Tita.ium Ca.bide pa.ticula.es (TiC), with a. a.era.e of 45nm, reinforcement were synthesized using low energy pla.eta.y ba.l mill followed by hot extrusion. Microstructura. cha.a.teriza.ion of the ma.eria.s revea.ed uniform distribution of reinforcement, gra.n refinement a.d the presence of minima. porosity. Properties cha.a.teriza.ion revea.ed tha. the presence of na.o-TiC pa.ticula.es led to a. increa.e in ha.dness, ela.tic modulus, 0.2% yield strength (0.2% offset on a.stress-stra.n curve), a.d the stress a. which a.ma.eria. exhibits a.specified perma.ent deforma.ion, Ultima.e Tensile Strength (UTS) a.d ductility of pure a.uminum. Fra.togra.hy studies revea.ed tha. the fra.ture of pure a.uminum occurred in ductile mode due to the incorpora.ion a.d uniform distribution of na.o-TiC pa.ticula.es. a. a.tempt is ma.e in the present study to correla.e the effect of na.o-sized TiC pa.ticula.es a. reinforcement a.d processing type with the micro structura. a.d tensile properties of a.uminum composites. The mecha.ica. properties, na.ely, the UTS, ha.dness, gra.n size a.d distribution of the reinforcement in the ba.e meta. were studied in a. sintered a.d extruded conditions. Orowa. strengthening criteria.wa. used to predict the yield strength of a.-TiC composites in the present work a.d experimenta. results were compa.ed with the theoretica. results.
