This paper investigates a hybrid wavelength division multiplexing (WDM) multiple access protocol combining the advantages of preallocation and reservation-based schemes using a subcarrier multiplexing (SCM) technique for passive double star optical networks. We include a node-grouping scheme in the proposed protocol to increase channel utilization and to reduce sensitivity to queueing delay tim...

Double black hole binaries are among the most important sources of gravitational radiation for groundbased detectors such as LIGO or VIRGO. Even if formed with lower efficiency than double neutron star binaries, they could dominate the predicted detection rates, since black holes are more massive than neutron stars and therefore could be detected at greater distances. Here we discuss an evoluti...

A “double star” is a tree with two internal vertices. It known that the Gyárfás–Sumner conjecture holds for double stars, is, every star H $H$ , there function f ${f}_{H}$ such if G $G$ does not contain as an induced subgraph then ? ( ) ? ? $\chi (G)\le {f}_{H}(\omega (G))$ (where ,\omega $ are chromatic number and clique of ). Here we prove can be chosen to polynomial.

چکیده: در گل های شاخه بریده به حداقل رساندن ضایعات پس از برداشت و افزایش عمر ماندگاری با در نظر گرفتن هزینه های بالای تولید امری بسیار مهم و ضروری است به خصوص در مورد گل های شاخه بریده رز که جایگاه خاصی در تجارت گیاهان زینتی دنیا دارند. گل رز از تیره گلسرخیان، با نام علمی rosahybrida می باشد. این تحقیق به منظور بررسی اثرات کاربرد سطوح مختلف نانو ذرات نقره بصورت تیمار مداوم و محلول پاشی در ارق...

We examine the vitrification and melting of asymmetric star polymer mixtures by combining rheological measurements with mode coupling theory. We identify two types of glassy states, a single glass, in which the small component is fluid in the glassy matrix of the big one, and a double glass, in which both components are vitrified. Addition of small-star polymers leads to melting of both glasses...
