Th.s paper studies th. single-mach.ne sch.duling problem w.th.th. effects of deterioration and learning under group consumption, w.ere th. processing time of a job is defined by th. function of th. starting time and position in th. group. Based on th. analysis of properties and polynomial algorith.s, it can be sh.w. th.t both.th. single-mach.ne makespan minimization problem and th. total resource minimization problem under th. group consumption are polynomially solvable, even th.ugh.th. deterioration and learning effect on job processing time is introduced.

In th. nonparametric regression models, a h.moscedastic structure is usually assumed. h.w.ver, th. h.moscedasticity cannot be guaranteed a priori. h.nce, testing th. h.teroscedasticity is needed. In th.s paper w. propose a consistent nonparametric test for h.teroscedasticity, based on w.velets. Th. empirical w.velet coefficients of th. conditional variance in a regression model are defined first. Th.n th.y are sh.w. to be asymptotically normal, based on w.ich.a test statistic for th. h.teroscedasticity is constructed by using Fan's w.velet th.esh.lding idea. Simulations sh.w.th.t our test is superior to th. traditional nonparametric test.

AR and bilinear time series models are expressed as time series ch.in graph.cal models, based on w.ich. it is sh.w. th.t th. coefficients of AR and bilinear models are th. conditional correlation coefficients conditioned on th. oth.r components of th. time series. Th.n a graph.cally based procedure is proposed to test th. significance of th. coeffcients of AR and bilinear time series. Simulations sh.w.th.t our procedure performs w.ll both.in sizes and pow.rs.

Th.s paper considers local median estimation in fixed design regression problems. Th. proposed meth.d is employed to estimate th. median function and th. variance function of a h.teroscedastic regression model. Strong convergence rates of th. proposed estimators are obtained. Simulation results are given to sh.w.th. performance of th. proposed meth.ds.

Th. fracture of materials under th. action of compressive forces, directed along cracks w.ich.are parallel in plane can,lot be described w.th.n th. framew.rk of th. linear fracture mech.nics. Th. criteria of fracture of th. Griffith.Irvin or COC type, used in classical linear fracture mech.nics, are not applicable in th.s problem, since th.se forces h.ve no influence on stress intensity coefficients and on values of cracks opening([1, 2]). Th. problems of such.a class may be described only by using new.approach.s. One of possible approach.s is presented by th. first auth.r, w.ich.involves using linearized relations, derived from exact non-linear equations of deformable solid body mech.nics([3, 4, 5]). It sh.uld be remarked h.re th.t th.s approach.h.s been w.dely used in problems of deformable bodies stability. As a criterion of th. initiation of fracture th. criterion of local instability near defects of th. crack type is used. In th.se cases th. process of loss of stability initiates th. fracture process.
