A variety of group 4 metal catalytic systems (C2-symmetric {EBTHI}-, {SBI}-type zirconocene complexes (C2-1–4); C1-symmetric (C1-5–8) and Cs-symmetric (Cs-9) {Cp/Flu}-type zirconocene complexes; Cp*2ZrCl2 (Cp* 2-10)), half-metallocene complexes (CpTiCl3, HM-11), constrained-geometry (CGC-12) titanium catalysts) and post-metallocene catalysts (Dow’s ortho-metallated amido-pyridino hafnium comple...

Depending on whether bidirectional links or unidirectional links are used for communications, the network topology under a given range assignment is either an undirected graph referred to as the symmetric topology, or a directed graph referred to as the asymmetric topology. The Min-Power Symmetric (resp., Asymmetric) k-Node Connectivity problem seeks a range assignment of minimum total power su...

چکیده: برش مورد مطالعه در 15 کیلومتری جاده ایلام به سمت مهران در منطقه ای تحت عنوان تنگ گراب قرار دارد. سازند گورپی متشکل از سنگهای نرم و تیره رنگ و لیتولوژی نرم بر روی سازند ایلام با سنگهای آهکی سخت و به رنگ سفید و نخودی قرار دارد. در این مطالعه تعداد 51 گونه متعلق به 23 جنس از فرامینیفرهای پلانکتونیک شناسایی و محدوده ی حضور آنها در برش مورد مطالعه تعیین شد. بر این اساس این سازند به 12 بایوزو...

We consider symmetric Markov chains on Zd where we do not assume that the conductance between two points must be zero if the points are far apart. Under a uniform second moment condition on the conductances, we obtain upper bounds on the transition probabilities, estimates for exit time probabilities, and certain lower bounds on the transition probabilities. We show that a uniform Harnack inequ...

The logarithmic transformation has long been used to present data that has both large and small components that are significant, such as neutron scattering data, or to present data that say covers a wide range of time-scales, such as NMR relaxation data. A more general transformation, that is applicable to many different disciplines, is offered here, that is particularly suitable for representi...

This paper describes a new, novel low computational-cost approach for recovering geometric structure and pose information of a 3D surface rotationally symmetric about an axis given an unorganized set of 3D range data which covers only a small patch of the surface. Self occluding contours are not seen here. All the parameters necessary to completely define the corresponding surface are estimated...
