چکیده
The metric around a ball with surface charge, obtained from the Einstein-Maxwell equations, has three independent parameters – radius and ball’s gravitational radius, equal to of matter. electric field energy there is only outside contributes same sign as Therefore, an increase in charge enhances effects gravity, increasing radii orbits shadows, redshifts deflection angles. At collapse, rest frame center, freezes above inner layers freeze matter inside them, i.e. collapsed becomes not black hole, but frozar, object gravitationally frozen structure. frozar’s follows its tends thus contains two instead three. located over total mass, for ball, finite. Observable consequences frozar are ball. On contrary, hole theory, Reissner-Nordström mass at infinity, which depends on diverges, since it includes diverging point charge. To ignore this divergence, was renormalized replaced “observable” mass. Then, already by mistake, dependence missed. result double disregard number unphysical consequences, inverse case complicated physical picture. It argued that horizons weakens gravity decreasing observable such redshifts, seriously stated positive antigravitates, physically absurd.

Consistent Binary Classification with Generalized Performance Metrics
Performance metrics for binary classification are designed to capture tradeoffs between four fundamental population quantities: true positives, false positives, true negatives and false negatives. Despite significant interest from theoretical and applied communities, little is known about either optimal classifiers or consistent algorithms for optimizing binary classification performance metric...

Software Metrics have become essential in software engineering for several reasons, among which quality assessment and reengineering. In the context of the European Esprit Project FAMOOS, whose main goal was to provide methodologies for the reengineering of large industrial software systems, we have developed the Moose Reengineering Environment, based on the language independent FAMIX metamodel...
متن کاملfinsler metrics with special landsberg curvature
in this paper, we study a class of finsler metrics which contains the class of p-reducible andgeneral relatively isotropic landsberg metrics, as special cases. we prove that on a compact finsler manifold,this class of metrics is nothing other than randers metrics. finally, we study this class of finsler metrics withscalar flag curvature and find a condition under which these metrics reduce to r...
متن کاملClassification using non-standard metrics
A large variety of supervised or unsupervised learning algorithms is based on a metric or similarity measure of the patterns in input space. Often, the standard euclidean metric is not sufficient and much more efficient and powerful approximators can be constructed based on more complex similarity calculations such as kernels or learning metrics. This procedure is benefitial for data in euclide...
