The origin and scaling of the current measured during steady electrospinning of polymer solutions in organic solvents is considered. It is demonstrated that, for a specified electric field strength, E, flow rate, Q, and conductivity, K, the total measured current scales as I TOTAL ~EQ 0.5 K 0.4 , for a wide variety of polymer solutions with different(More)
The seminal ideas of de Gennes and Doi and Edwards have provided the theoretical framework for much of the recent effort to model the rheological behavior of entangled polymer melts and solutions. Recent theoretical work has incorporated a number of important additions to the basic Doi-Edwards theory, including an explicit description of chain stretch and(More)
In the present study we have proposed a secured geocaste routing in VANET with two stage efficient communication protocol. The communication protocol operates on two stages. In the first stage vehicles transmit messages within its transmission range of its radar and to the VANET Server. In the second stage VANET Server receives messages from vehicles and(More)
4-G mobile communications system is offering high speed data communications technology having connectivity to all sorts of the networks including 2-G and 3-G mobile networks. Authentication of a mobile subscriber (MS) or a subnetwork and a main network are an important issue to check and minimize security threats or attacks. An advanced artificial(More)
(servers in PDSN) examines the authenticity of MS. In this paper, we propose a mutual authentication technique that verifies the authenticity of the subscriber as well as the network by subscriber's password, SIM and biometric property of the subscriber. Two biometric parameters are used in which one biometric parameter is stored in SIM and the other(More)

Authentication of mobile subscribers and network are a challenging issue to the researchers due to increasing security threats and attacks with the enhanced population of wireless traffic. 3-G or advanced mobile communication system has been developed to speed up the data communication. 3-G mobile communications use two different switching techniques:(More)
—Two types of ad hoc networks in mobile communications are mainly existing; one is Mobile Ad Hoc Network (MANET) and other one Vehicular Ad Hoc Network (VANET). Vehicular Ad Hoc Network (VANET) is highly demanded wireless ad hoc network. It is based on IEEE 802.11 wireless standard, which facilitates vehicle to vehicle and vehicle to roadside communications(More)
—Different logic gates like MV, NOT, AOI, NNI etc under QCA nanotechnology are introduced. NNI gate is highly effective regarding space and speed consideration. Any Boolean functions are synthesized by MV and NNI gates or simply NNI gates alone, eliminating inverter (NOT) gate. A new method for realizing adder circuit in binary reversible logic is invented.(More)
