Several Trade off Features of Quantum Steering in Distributed Scenario

Abstract: In the present work, we address the question of how bipartite steering violation takes place among multi-partite systems (where each sub-system have Hilbert space dimension restricted to two) based on the maximal violations of the bipartite steering inequality of the reduced pairwise qubit systems. We have derived a trade-off relation which is satisfied by those pairwise bipartite maximal steering violations, which physically can be understood as providing restrictions on the distribution of steering among subsystems. For a three-qubit system, it is impossible that all pairs of qubits violate the steering inequality, and once a pair of qubits violates the steering inequality maximally, the other two pairs of qubits must both obey the steering inequality. We also present a complementarity relation between genuine entanglement present in a tripartite state and maximum bipartite steering violation by its reduced states.

Addressing the valuation problem in multi-round combinatorial auctions

Abstract: Multi-round combinatorial auctions have been infrequently employed for essentially two reasons, the computational complexity of the Winner Determination Problem, and the need to provide information feedback to bidders to enable them to bid meaningfully. Here we take a fresh look at the second issue. In business environments, a bidder's valuation of a package can change in response to signals from other bidders. In the absence of feedback, bidders are forced to expend time and resources to determine these package valuations as accurately as possible. We propose a multi-round combinatorial auction scheme with inter-round feedback called RevalSlot that helps a bidder to converge to an appropriate valuation for a package. This is likely to prove attractive to bidders and thereby increase bidder participation. We also propose a simplified version of the scheme called RevalBundle that requires fewer solutions of the Winner Determination Problem.

Laminated Composite Hypar Shells as Roofing Units: Static and Dynamic Behavior

Abstract: This chapter presents a broad perspective of the recent research done on laminated composite hypar shells used as roofing units. Different types of analysis including bending, vibration, buckling, impact, and failure are included. The chapter is collated and categorized based on various aspect of research. The first aspect concentrates on typical analyses including problems in which various boundary conditions and laminations are considered. Then it focuses on the structural complexities which include stiffened shells, shells with cutouts, etc. The basic results of theoretical and experimental investigations of stress-strain state, vibration, buckling, and failure are summarized in this chapter incorporating the review of materials published in scientific and technical journals and proceedings in recent times.

Design of UWB filter using DGS and Slot SRR array with band rejection for IEEE 802.11a WLAN

Abstract: In this paper an ultra-wideband filter is designed using periodic defected ground structures as low pass filter and Slot SRRs in the conducting strip as a band reject filter to prevent interference from WLAN. The high pass characteristic is obtained by an interdigital capacitor in the conducting strip. The average insertion loss is 1.6 dB in the passband. The band stop filter rejects frequencies from 5.21 GHz to 5.9 GHz with maximum rejection being -33.46 dB at 5.4 GHz and stopband rejection is upto -68.61 dB and -60dB in the upper and lower stop-bands respectively. Keywords-communication systems, ultrawideband technology, microwave filters, SRRs, WLAN.

Studies on Solvent Extraction of Ethanol during Fermentation under Agitated Condition

Abstract: In the present investigation, an attempt has been made to study the effect of agitation on simultaneous fermentation and extraction of ethyl alcohol in the presence of ethyl benzene as solvent. Three separate studies, viz. agitation of both the aqueous and non-aqueous phases at the same rotational speed of agitator (the range being 100–300 rpm), agitation of the non-aqueous phase keeping the aqueous phase static and agitation during fermentation in the absence of solvent, were carried out. In each case, Sacchoromyces cerevisiae was used as the microorganism in the production media with 10% (w/v) glucose as substrate at 30°C. It was observed that, in general, an increase in agitator speed decreased ethanol production under a solvent-free system. Under the aqueous phase static and organic phase agitated conditions, the maximum yield of ethanol in aqueous phase was obtained at a 200 rpm agitator speed after 12 h of incubation. It was further noticed that extraction of ethanol in the organic phase in...
