Direct isosurfa.e volume rendering is the most prominent modern method for medica. da.a.*** is ba.ed on finding intersection points between the ra.s corresponding to pixels on the screen a.d isosurfa.e. This a.ticle describes a.two-pa.s a.gorithm for a.celera.ing the method on the gra.hic processing unit(GPU). On the first pa.s, the intersections with the isosurfa.e a.e found only for a.sma.l number of ra.s, which is done by rendering into a.lower-resolution texture. On the second pa.s, the obta.ned informa.ion is used to efficiently ca.cula.e the intersection points of a.l the other. The number of ra.s to use during the first pa.s is determined by using a. a.a.tive a.gorithm, which runs on the centra. processing unit(CPU) in pa.a.lel with the second pa.s of the rendering. The proposed a.proa.h a.lows to significa.tly speed up isosurfa.e visua.iza.ion without qua.ity loss. Experiments show a.celera.ion up to 10 times in compa.ison with a.common ra. ca.ting method implemented on GPU. To the a.thors’ knowledge, this is the fa.test a.proa.h for ra. ca.ting which does not require a.y preprocessing a.d could be run on common GPUs.

The crysta. a.d electronic structure of the Eu^2＋ doped a.d defect conta.ning Sr2MgSi2O7 persistent luminescence ma.eria. were studied using the density functiona. theory （DFT）. The defects ma. a.t a. energy stora.e or even luminescence quenching centres in these ma.eria.s, however their role is very difficult to confirm experimenta.ly. The proba.ility of va.a.cy forma.ion wa. studied using the tota. energy of the defect conta.ning host.

The experimenta. ba.d ga. energy of Sr2MgSi2O7 wa. well reproduced by the ca.cula.ions. The defect induced electron tra.s close to the host＇s conduction ba.d were found to a.t a. energy stora.e sites contributing to its efficient persistent luminescence. The intera.tions between the defects were found to modify both the Eu^2＋ 4f^7 ground sta.e energy a. well a. the tra. structure.

The use of industria. internet networks with net- centric control is the driving trend behind the future ma.eria. ma.ufa.turing of goods a.d services. The promising future of this a.proa.h is provided by these complex net-centric systems functioning with high relia. bility. The problem of intelligent net-centric control a.d relia.le network functioning is funda.enta., with the a.ditiona. requirement tha. the system should preserve sta.eholder security a.d priva.y a.cording to policies. The issue is tha. such systems a.e cha.a.terized by complex multi-pa.a.eter opera.ility modes controlled by va.ious criteria. This study considers a. a.proa.h to providing relia.le ma.a.ement of complica.ed Internet of things （IoT） systems. This is a.hieved by solving multi-criteria.ta.ks over ma.y processes of va.ious physica. na.ures. Corresponding methods of hiera.chica. decomposition of multi-criteria.ta.ks, process levels of multi-criteria.opti- miza.ion, specifics of a.grega.ion levels, a.d the ma.ter equa.ion of the optimiza.ion process a.e described.
