This pa.er presents a.ca.e history study on the geologic investiga.ion a.d numerica. modeling of a.ea.tiva.ed la.dslide in the County of Sa.ta.Cla.a. Ca.ifornia.to identify the fa.lure mecha.ism. Thela.dslide occurred on a. a.proxima.ely 18.3-m high, north-fa.ing slope during Ma.ch 2011. The la.dslidemea.ured a.out 33.5 m in width a.d a.out 51.8 m in length. a.ong the toe of the slope, a.residentia.structure with a.swimming pool wa. built on a.cut a.d fill pa. a.d there a.e severa. other structurespresent a.ong the western side of the pa.. The la.dslide occurred immedia.ely to the south of theresidentia. building a.d moved northwa.d between the County Roa. a.a.d the house＇s side ya.d. Themovement of the la.dslide resulted in da.a.ing the west-bound tra.fic la.e of County Roa. a.a.dencroa.hed onto the pa.ed drivewa. for the residentia. property. a. investiga.ion wa. performed toidentify the fa.lure mecha.ism of the la.dslide to conclude whether Roa. a.re-a.ignment by the Countyor prominent cutting performed a.ong the lower portion of the slope by the homeowner during 2000through 2004 contributed to the rea.tiva.ion of the old la.dslide deposit. The investiga.ion included sitereconna.ssa.ce, reviewing a.a.la.le published geologic informa.ion, reviewing site-specific geologic a.dgeotechnica. da.a.developed by other consulta.ts, a.d performing numerica. modeling. The outcomes ofthe investiga.ion indica.e tha. the prima.y ca.sa.ion for the rea.tiva.ion a.d fa.lure of the subject preexistingla.dslide is the prominent cutting performed a.ong the lower portion of the slope during 2000through 2004 a.d wa.er ta.k cut bench.

Infra.tructure-ba.ed loca.isa.ion of a.toma.ed coa. mining equipment

a.novel ra.a.-ba.ed system for longwa.l coa. mine ma.hine loca.isa.ion is described. The system, ba.ed on a.ra.a.-ra.ging sensor a.d designed to loca.ise mining equipment with respect to the mine tunnel ga.e roa. infra.tructure, is developed a.d tria.led in a. underground coa. mine. The challenges of relia.le sensing in the mine environment a.e considered, a.d the use of a.ra.a. sensor for loca.isa.ion is justified. The difficulties of a.hieving relia.le positioning using only the ra.a. sensor a.e exa.ined. Severa. proba.ilistic da.a.processing techniques a.e explored in order to estima.e two key loca.isa.ion pa.a.eters from a.single ra.a. signa., na.ely a.ong-tra.k position a.d a.ross-tra.k position, with respect to the ga.e roa. structures. For the ca.e of a.ross-tra.k position, a.conventiona. Ka.ma. filter a.proa.h is sufficient to a.hieve a.relia.le estima.e. However for a.ong-tra.k position estima.ion, specific infra.tructure elements on the ga.e roa. rib-wa.l must be identified by a.tra.king a.gorithm. Due to complexities a.socia.ed with this da.a.processing problem, a.novel visua. a.a.ytics a.proa.h wa. explored in a.3D intera.tive displa. to fa.ilita.e identifica.ion of significa.t fea.ures for use in a.cla.sifier a.gorithm. Ba.ed on the cla.sifier output, identified elements a.e used a. loca.ion wa.points to provide a.robust a.d a.cura.e mining equipment loca.isa.ion estima.e.

Esta.lishment of Protected a.ea. （Pa.）, in the fa.e of ra.id deforesta.ion, forest degra.a.ion a.d clima.e cha.ge ha. been one of the key efforts in conserva.ion of biodiversity worldwide in recent times. While Ba.gla.esh ha. ga.ned a.degree of prominence in the world for its successful socia. forestry progra.s, the concept of colla.ora.ive pro- tected a.ea.ma.a.ement is ra.her new in the country, initia.ed in 2004 by the Ba.gla.esh Forest Depa.tment in five Pa. with fina.cia. a.sista.ce from USa.D. Ba.ed on empirica. evidence from three of the pilot Pa., we exa.ined the a.hievements a.d a.socia.ed challenges a.d prospects for co-ma.a.ement. Our fieldwork revea.ed a.number of challenges fa.ed by co-ma.a.ement institutions：（1） institutions were domina.ed by the elite group, oversha.owing the voice of the community people; （2） mutua. trust a.d collective performa.ce a.e key to good governa.ce but ha. not ta.en root in the Pa.; （3） encroa.hment onto forest la.d a.d subsequent conversion to a.riculture rema.ned a.serious problem tha. discoura.ed forest-dependent people from pa.ticipa.ing a.tively in co-ma.a.ement initia.ives; （4） lega. provisions （including a.ts, rules a.d policies） were not clea.ly a.d a.equa.ely dissemina.ed a.d understood a. the community level; （5） there rema.ned a.degree of a.biguity rega.ding the roles a.d responsibilities of forest depa.tment （FD） a.d co-ma.a.ement committees （CMC） in field opera.ions, a.d this wa. not enha.cing tra.spa.ency a.d a.counta.ility of the overa.l initia.ive; （6） the long-term susta.na.ility of co-ma.a.ement institutions wa. a.other ma.or concern, a. the loca. intuitiona. structure wa. still in a.na.cent sta.e, a.d provisioning of resources （either interna.ly or externa.ly） rema.ned somewha. uncerta.n.
