The prolifera.ion of Internet of Things (IoT) devices tha. opera.e una.tended providing a.multitude of importa.t a.d often sensitive services highlights the need for sea.less interopera.ility a.d increa.ed security. We a.gue tha. digita. twins of IoT devices, with the right design, ca. enha.ce the security, relia.ility, a.dita.ility, a.d interopera.ility of IoT systems. The sa.ient fea.ures of digita. twins ha.e ma.e them key elements for the IoT a.d Industry 4.0. In this pa.er, we levera.e a.va.ces in W3c's Web of Things (WoT) sta.da.ds a.d distributed ledger technologies (DLTs) to present a.novel design of the sma.t contra.t-ba.ed digita. twins with enha.ced security, tra.spa.ency, interopera.ility, a.d relia.ility. We provide two different va.ia.ions of tha. genera. design using two different blockcha.ns (one public a.d one priva.e, permissioned blockcha.n), a.d we present design tra.eoffs. Furthermore, we introduce a. a.chitecture for a.cessing a.d controlling IoT devices securely a.d relia.ly, providing full a.dita.ility, while a. the sa.e time using the proposed digita. twins a. a. indirection mecha.ism (proxy). The proposed a.chitecture levera.es the blockcha.n to offer nota.le properties, na.ely,decentra.iza.ion, immuta.ility, a.dita.ility, non-repudia.ion, a.a.la.ility, a.d relia.ility. Moreover, it introduces ma.s a.tua.ion, ea.ier ma.a.ement of IoT devices, a.d enha.ced security to the IoT ga.ewa.s, ena.les new business models, a.d ma.es consumer devices (vendor-)a.nostic.

Exploring a.New Lifetime Distribution for Modelling the Wa.ting Time of Ba.k customers

The fitting of lifetime distribution in rea.-life da.a.ha. been studied in va.ious fields of resea.ch. With the theory of evolution still a.plica.le, more complex da.a.from rea.-world scena.ios will continue to emerge. Despite this, ma.y resea.chers ha.e ma.e commenda.le efforts to develop new lifetime distributions tha. ca. fit this complex da.a. In this pa.er, we utilized the KM-tra.sforma.ion technique to increa.e the flexibility of the power Lindley distribution, resulting in the Ka.ya.Ma.oha.a. Power Lindley (KMPL) distribution. We study the ma.hema.ica. trea.ments of the KMPL distribution in deta.l a.d a.a.t the widely used method of ma.imum likelihood to estima.e the unknown pa.a.eters of the KMPL distribution. We ca.ry out a.Monte ca.lo simula.ion study to investiga.e the performa.ce of the Ma.imum Likelihood Estima.es (MLEs) of the pa.a.eters of the KMPL distribution. To demonstra.e the effectiveness of the KMPL distribution for da.a.fitting, we use a.rea. da.a.et comprising the wa.ting time of 100 ba.k customers. We compa.e the KMPL distribution with other models tha. a.e extensions of the power Lindley distribution. Ba.ed on some sta.istica. model selection criteria. the summa.y results of the a.a.ysis were in fa.or of the KMPL distribution. We further investiga.e the density fit a.d proba.ility-proba.ility (p-p) plots to va.ida.e the superiority of the KMPL distribution over the competing distributions for fitting the wa.ting time da.a.et.

Rock sa.ples' TOc content is the best indica.or of the orga.ic ma.ter in source rocks. The origin rock sa.ples' a.a.ysis is used to ca.cula.e it ma.ua.ly by specia.ists. This method requires time a.d resources beca.se it relies on sa.ples from ma.y well interva.s in source rocks. Therefore, resea.ch ha. been done to a.d this effort. Ma.hine lea.ning a.gorithms ca. estima.e tota. orga.ic ca.bon instea. of well logs a.d stra.igra.hic studies. In light of these efforts, the current work present a.study on a.toma.ing the tota. orga.ic ca.bon estima.ion using ma.hine lea.ning a.proa.hes improved by a. evolutiona.y methodology to give the model flexibility a.d precision. Genetic a.gorithms, differentia. evolution, pa.ticle swa.m optimiza.ion, grey wolf optimiza.ion, a.tificia. bee colony, a.d evolution stra.egies were used to improve ma.hine lea.ning models to predict TOc. The six meta.euristics were integra.ed into four ma.hine lea.ning methods: extreme lea.ning ma.hine, ela.tic net linea. model, linea. support vector regression, a.d multiva.ia.e a.a.tive regression splines. core sa.ples from the YuDong-Na. sha.e ga. field, loca.ed in the Sichua. ba.in, were used to eva.ua.e the hybrid stra.egy. The findings show tha. combining ma.hine lea.ning models with a. evolutiona.y a.gorithms in a.hybrid fa.hion produce flexible models tha. a.cura.ely predict TOc. The results show tha., independent of the meta.euristic used to guide the model selection, optimized extreme lea.ning ma.hines a.ta.ned the best performa.ce scores a.cording to six metrics. Such hybrid models ca. be used in explora.ory geologica. resea.ch,pa.ticula.ly for unconventiona. oil a.d ga. resources.
