Using the isospin-dependent quantum molecular dynamics model, we study the effect of charge asymmetry and isospin-dependent cross section on nuclear stopping and multiplicity of free nucleons and light mass fragments. Simulations were carried out for the reactions 124X<inf>m</inf>+124X<inf>m</inf>, where m varies from 47 to 59 and for 40Y<inf>n</inf>+40Y<inf>n</inf>, where n varies from 14 to 23. Our study shows that nuclear stopping depends strongly on the isospin of the cross section. © 201...

Future network's main requirements are compact size, support to heterogeneous network which drive the requirements for multiband support. Self-similar shaped structure have useful applications in cellular telephone and microwave communications etc. Video conferencing, streaming video are main applications that are included in future networks and requirements for these applications are high data rates which require to have high bandwidth. But our aim to derive an antenna which works on large b...

In this paper, an introduction and overview of MEMS technology with a focus on RF applications of MEMS in the design of mobile terminal are presented. Such RF MEMS switches have displayed excellent RF characteristics, including lower insertion loss, higher isolation, zero power consumption, small size and weight and very low intermodulation distortion, and long battery life. It is desirable for a single device to access the additional several services like DCS, PCS, GSM, EGSM, CDMA, WCDMA, GP...

We study warped product semi-invariant submanifolds of nearly cosymplectic manifolds. We prove that the warped product of the type M⊥×fMT is a usual Riemannian product of M⊥ and MT , where M⊥ and MT are anti-invariant and invariant submanifolds of a nearly cosymplectic manifold M, respectively. Thus we consider the warped product of the type MT×fM⊥ and obtain a characterization for such type of warped product.

In the literature, several methods are proposed for solving transportation problems in fuzzy environment but in all the proposed methods the parameters are represented by normal fuzzy numbers. [S.H. Chen, Operations on fuzzy numbers with function principal, Tamkang Journal of Management Sciences 6 (1985) 13–25] pointed out that in many cases it is not to possible to restrict the membership function to the normal form and proposed the concept of generalized fuzzy numbers. There are several...

Recent development in wireless sensor network (WSN) has shown the importance of routing protocols as they differ in application and networking architecture. The efficiency of WSNs strongly depends on the routing protocol used. In this paper, we have discussed some of the important protocols of network and data-link layer. Various issues such as energy efficiency, lifetime, scalability of network and mobility of nodes have been discussed here. The paper concludes with open research issues.

In this paper, a pair of second-order multiobjective mixed symmetric dual programs over arbitrary cones is formulated. The usual duality results are then established for the aforementioned pair using the notion of η-bonvexity/η-pseudobonvexity assumptions.

Materialseries with compositional formula Ba0.9Sr0.1ZrxTi1xO3 (BSZT) were prepared by conventionalsolid state reaction route. XRD pattern shows that all the samples are well crystallized into perovskite structure. Tetragonality was found to decrease with increase in Zr content. Effect of substitution of Zr on dielectric constant, tangent loss and nature of transition temperature is discussed in the present paper.

BACKGROUND: The effect of coupled biological and photochemical processes for treatment of bio-recalcitrant effluents from chlorination (C) and first alkaline extraction (E1) stages of soda pulp bleaching in an agro-residue based pulp and paper mill has been investigated. RESULTS: The work aims to evaluate the coupled effect on the extent of degradation in terms of chemical oxygen demand (COD) reduction. Biological treatment of C and E1 effluent resulted in 30% and 57% COD, respectively, a...
