The Al-alloying treated tungsten carbide (WC)-Co tool was subjected to grinding using a jaw crusher and planetary mill followed by three wet chemical treatment steps to establish an effective recycling process for WC scraps, especially those generated as bulky and hard scrap. This alloyed WC tool was readily ground to a powder of 1 mm or less and divided into two portions that were 150 μm in si...

We propose and estimate a novel transport layer mobility management scheme: Seamless IP diversity based Generalized Mobility Architecture (SIGMA). SIGMA provides seamless handover for mobile hosts and is based on Stream Control Transmission Protocol (SCTP), which is a new dependable transport protocol to transport SS7 signaling messages over IP network. We also show that our handover scheme can...

Punicagranatum cv. Malassaveh is one of the most desirable commercial cultivars in Iran. In thisstudy some experiments were conducted to introduce the best hormonal treatments for directadventitious shoot regeneration from mentioned cultivar via cotyledonary explants. For thispurpose, both liquid and agarMurashige and Skoog (1962) (MS) medium supplemented with BAat 2, 4.5, 9, 13 μM alone and in...

Paging is a well established technique to reduce signalling cost in mobile devices. Different proposals in literature has shown the implementation and improvement of Mobile IP with paging. Here we propose P-SIGMA, an improved, more signalling cost effective version of SIGMA, an IP diversity based end to end transport layer mobility scheme. We show that with all the benefits of a transport layer...

Let $S(G^{sigma})$ be the skew-adjacency matrix of the oriented graph $G^{sigma}$, which is obtained from a simple undirected graph $G$ by assigning an orientation $sigma$ to each of its edges. The skew energy of an oriented graph $G^{sigma}$ is defined as the sum of absolute values of all eigenvalues of $S(G^{sigma})$. Two oriented graphs are said to be skew equienergetic iftheir skew energies...
