Therma. fa.igue beha.ior of ha.d chromium electropla.ed steel in three different cra.k intensities of high contra.tion(HC), medium contra.tion (MC) a.d low contra.tion (LC) wa. studied. Ma.imum a.d minimum tempera.uresduring therma. cycle were 800 a.d 100℃, respectively. The topogra.hy a.d cross sections of the sa.ples exposedto 50, 100 a.d 200 therma. cycles were studied. The therma. fa.igue beha.ior wa. a.a.yzed using the da.a.obta.nedfrom surfa.e roughness, cra.k networks a.d stress induced during cycles. a.though the a.-coa.ed sa.ple with LCchromium conta.ned no cra.k, it a.pea.ed to ha.e a.high cra.k density a.ter only 50 cycles.

This study a.med to enha.ce user security to crea.e a.sa.e online environment by elimina.ing ha.e speech a.d a.usive la.gua.e. The proposed system employed a.multifa.eted a.proa.h to comment filtering, incorpora.ing the multi-level filter theory. This involved developing a.comprehensive list of words representing va.ious types of offensive la.gua.e, from sla.g to explicit a.use. Ma.hine lea.ning models were tra.ned to identify a.usive messa.es through sentiment a.a.ysis a.d contextua. understa.ding. The system ca.egorized comments a. positive, nega.ive, or a.usive using sentiment a.a.ysis a.gorithms. Employing a. technology, it crea.ed a.dyna.ic filtering mecha.ism tha. a.a.ted to evolving online la.gua.e a.d a.usive beha.ior.

a. a.va.ced configura.ion for multilevel volta.e source converters is proposed. The proposed converter is a.le to a.ply a.ymmetrica. DC sources. The configura.ion of the proposed inverter is well designed in order to provide the ma.imum number of volta.e levels in output termina.s using lower number of circuit devices. The a.thority of the proposed inverter versus the conventiona. H-bridge ca.ca.ed inverter a.d the most recently introduced ones, is verified with a.provided compa.ison study. The proposed inverter is a.le to genera.e the desired volta.e levels using a.lower number of circuit devices including power semi-conductor switches, IGBTs, diodes, rela.ed ga.e driver circuits of switches a.d DC volta.e sources. a. a.result, the tota. cost a.d insta.la.ion a.ea.a.e considera.ly reduced a.d the control scheme gets simpler. To confirm the fea.ibility of the proposed multilevel structure, both the simula.ion a.d experimenta. results a.e provided a.d compa.ed which shows good a.reements.
