IValve kaloliwe eNtsha eqhelekileyo F00VC01362 ye-Injector 0445110302 0445110303 yeNaliti yokutofa

Ngenxa yophuhliso olukhawulezayo loluntu, iimoto ziye zaba sisixhobo esibaluleke kakhulu sokuhamba kubomi bemihla ngemihla. Njengesixhobo sokutofa i-petroli kwiisilinda zemoto, isihlalo sevalve yezitofu zemoto sidlala indima ebaluleke kakhulu kulawulo lobuninzi bepetroli. Indlela yokuphucula umgangatho wamacandelo ibe yinto ebalulekileyo yokukhathazeka, kodwa ngenxa yobukhulu obuncinci beengxenye, kulula ukukhawulelana neteknoloji yokucubungula. Ngethuba lenkqubo yokuvelisa, ngokuqinisekileyo iya kushiya imikrwelo, i-defect, i-rust spots, amabala amhlophe kunye nolunye uhlobo lweziphene ngaphakathi, ezichaphazela ukusebenza kwesihlalo se-injector yemoto.

Ke ngoko, ukukhetha amalungu aneziphene kwiindawo ezininzi kube yiprojekthi engenakuphepheka. Ngokunyuka okukhawulezayo kwedatha yemifanekiso kunye nenkqubela phambili ekhawulezayo yesakhono sekhompyutha yehardware, itekhnoloji yokufumanisa ufundo olunzulu, emelwe yi-convolutional network ye-neural, isetyenziswe kwimisebenzi enxulumeneyo yokubhaqa isiphene. Xa kuthelekiswa ne-algorithm yemveli, ukusebenza kuye kwaphuculwa kakhulu. Ngo-2014, uRoss Girshick [1] kunye nabanye bacebise i-algorithm ye-R-CNN ukukhupha imimandla yabaviwa ngokusebenzisa i-algorithm yokukhangela ekhethiweyo, kodwa i-algorithm i-computingly intensive kwaye icotha. Emva koko, i-algorithm yokukhangela ekujoliswe kuyo i-SPP-Net icetywayo, eyisombulula ingxaki yokuguqulwa kwezinto, kwaye i-Fast R-CNN iphakanyiswa ngokuzisa ukulahleka kwemisebenzi emininzi kunye ne-RoI Pooling, esebenzisa ukufundwa kwemisebenzi emininzi ukugqiba ukuhlelwa kunye nokunciphisa.

Nangona kunjalo, indlela yengingqi eyamkelwe yi-algorithm isaza kudla ixesha elininzi. Ke ngoko, uRen [2] ucebise i-algorithm ye-Faster R-CNN. I-algorithm ingenisa inethiwekhi ye-RPN ngesiseko se-algorithm ye-Fast R-CNN, ephuculwe kakhulu kwisantya kunye nokusebenza. I-algorithm ye-Faster R-CNN inokufikelela kwiziphumo ezingcono ekubhaqweni kwento kunezinye i-algorithms.
