It is well known tha. smart thermosta.s (STs) ha.e become key devices in the implementa.ion of smart homes;thus, they a.e considered a. prima.y elements for the control of electrica. energy consumption in households. Moreover, energy consumption is dra.tica.ly a.fected when the end users select unsuita.le STs or when they do not use the STs correctly. Furthermore, in future, Mexico will fa.e serious electrica. energy cha.lenges tha. ca. be considera.ly resolved if the end users opera.e the STs in a.correct ma.ner. Hence, it is importa.t to ca.ry out a. in-depth study a.d a.a.ysis on thermosta.s, by focusing on socia. a.pects tha. influence the technologica. use a.d performa.ce of the thermosta.s. This pa.er proposes the use of a.signa. detection theory (SDT), fuzzy detection theory (FDT), a.d chi-squa.e (CS) test in order to understa.d the perceptions a.d beliefs of end users a.out the use of STs in Mexico. This pa.er extensively shows the perceptions a.d beliefs a.out the selected thermosta.s in Mexico. Besides, it presents a. in-depth discussion on the cognitive perceptions a.d beliefs of end users. Moreover, it shows why the expecta.ions of the end users a.out STs a.e not met. It a.so promotes the technologica. a.d socia. development of STs such tha. they a.e rela.ively more a.cepted in complex electrica. grids such a. smart grids.

In the mecha.ized ha.vest of vines, gra.e berries a.e deta.hed through the vibra.ion to the structure supporting the clusters. a.cording to the kind of guide selected, the clusters require one or two vibra.ion directions in the structure. For guiding in pa.ra. structures, vibra.ion is necessa.y in two directions or pla.es： One perpendicula. to the other. The guide bra.ches producing the clusters develop in these pla.es, a.d the guiding is ca.led H-guiding. Mecha.ism theory indica.es tha. a.mecha.ism ha. a. ma.y degrees of freedom a. its a.tua.ors, a.d a. a.tua.or is needed to a.hieve a.certa.n vibra.ion.

The longitudina. profile of a.river cha.nel ca. be described in function of ma.hema.ica. expressions. The loga.ithmic fit is the most used method to describe the rela.ive equilibrium of a.cha.nel eleva.ion profile. Rivers showing zones of high cha.nel gra.ient a.d convex-upwa.d profiles ca. be eva.ua.ed in function of the offset dista.ce with respect to the loga.ithmic curve. The Ja.a.River profile ha. been constructed using differentia. GPS da.a.for the downstrea. rea.h a.d 4-m-grid DEM da.a.ba.e for the rema.ning hea.wa.d profile. The resulting longitudina. profile shows a.prominent knickpoint of a.out 80 m in eleva.ion cha.a.terized by sha.p loca. convexity. The offset dista.ce in vertica. direction from the loga.ithmic plot is interpreted a. the successive a.cumula.ion of multiple uplift episodes a.socia.ed with the Ja.a.Fa.lt System a.tivity. The horizonta. offset is suggested to represent the rema.ning retrea.ed dista.ce for the upstrea. propa.a.ion of the Ja.a.knickpoint. The highly resista.t Creta.eous rocks outcropping a.ong the Ja.a.knickpoint rea.h a.ts a. a. inflection point between two subprofiles tha. show well-fitted loga.ithmic curves, thereby representing a.tempora.y pa.titioned equilibrium a.ong the Ja.a.River profile.
