چگونگی تغییر هزینه های تعمیر و نگهداری بدلیل تصادفی بودن آنها بشدت وابسته به شرایط منطقه ای می باشد. بنابراین برای برآورد هزینه هایی مانند هزینه استهلاک، نمی توان رابطه استاندارد پیشنهاد کرد ولی می توان در حد قابل قبولی ...

We describe a construction which yields unbounded derivations

and strongly continuous one-parameter automorphism groups of certain

group C*-algebras. As an application, we show that a simple C*-algebra can

have an automorphism...

In this note we show that any derivation of a simple C*-algebra,

whose range is not dense, is closable. We also derive a necessary and sufficient condition

for a *-derivation of a C*-algebra, which is defined on the domain of a closed...

The research community has recently witnessed the

emergence of Multi-Processor System on Chip

(MPSoC) platforms consisting of a large set of

embedded processors. Particularly, Interconnect

networks methodology based...

In this paper, we determine the behavior of the c-nilpotent multi-
plier of Lie algebras with respect to the direct sum. Then we give some results
on the c-capability of the direct sum of nite dimensional Lie algebras....

The five-toed jerboas of the genus Allactaga

inhabit arid areas of Asia and North Africa and are widely

distributed in deserts, semideserts, and steppe regions

of Iran. Many morphological and morphometric ...
