TL;DR: In this article, a majority-layered T hybridization is proposed to synthesize the reversible circuits using QCA, which can realize the area-efficient QCA counterparts of reversible benchmark circuits.
Abstract: The atomistic quantum-dot cellular automata (QCA) based implementations of the reversible circuits have got tremendous exposures in the last few days, due to “room-temperature workability” of the QCA. The researchers are in serious need of a methodology that can realize the area-efficient QCA counterparts of reversible benchmark circuits. In this work, a novel methodology named majority-layered T hybridization is proposed to synthesize the reversible circuits using QCA. Firstly the reversible library consisting of CNTS Gates have been generated to validate the usability of the proposed methodology. Then, an elementary QCA module of 3×3 Toffoli Gate have been proposed and extended in the realization of 4×4, 5×5 and 6×6 Toffoli Gates (multi-control Toffoli Gates). The proper mathematical modelling of the several QCA design metrics like effective area, delay and O-cost has been established. The QCA counterpart of 3×3 Toffoli Gate reports 18.61% less effective area and 8.33% less O-cost compared to th...

TL;DR: In this paper, a new electronically tunable differential input integrator (ETDII) using the composite current feedback amplifier (CFA) and multiplication-mode current conveyor (MMCC) building block is presented, wherein the control voltage (Vc) of the MMCC tunes its time constant (τ).
Abstract: A new electronically tunable differential input integrator (ETDII) using the composite current feedback amplifier (CFA) and multiplication-mode current conveyor (MMCC) building block is presented, wherein the control voltage (Vc) of the MMCC tunes its time constant (τ). Effects of the device parasitic capacitances had been examined and appropriate compensation design is proposed to obtain high-quality (q) realization. Analysis shows that τ is practically active insensitive to device port mismatch errors (ϵ). A quadrature voltage controlled oscillator (VCO) is implemented utilizing the ETDII after suitably configuring a double-integrator loop with grounded capacitors in the same topology. With the loop closed, the ETDII topology realizes some new electronically tunable synthetic immittance function at appropriate nodes. Satisfactory experimental results for the proposed realizations had been verified with PSPICE macro-model simulation and by hardware test.

TL;DR: This model is extended and applied for tracking of multiple cloud clusters so that it can be utilized for weather nowcasting.
Abstract: Thermal infrared images are quite useful in detection of convective clouds for meteorological purposes. Several techniques are available for the detection and tracking of clouds in satellite thermal infrared images. Temperature induced mean based cloud motion prediction model is one of them. But so far, it has been implemented for tracking single cloud cluster. In the present work this model is extended and applied for tracking of multiple cloud clusters so that it can be utilized for weather nowcasting.

TL;DR: Transmission map is a crucial reference to retrieve the dehazed output in single image dehazing, and it is suggested that this map should be placed at the top of the output list to facilitate easy retrieval of the data.
Abstract: Single image dehazing is an ill-posed, challenging issue out of several dehazing techniques due to its limited information. Transmission map is a crucial reference to retrieve the dehazed o...

TL;DR: A compromise-tolerant DTN is envisioned, where time-varying pseudonyms are used to obscure the actual identity and safeguard the privacy of genuine nodes, and unique implicit session key agreement facilitates the establishment of credential-free secure communication session between two legitimate nodes and protects the data from being revealed to the adversaries.
Abstract: Researchers have proposed to set up "infrastructure-less" peer-to-peer opportunistic network (also known as Delay Tolerant Network) using smart phones carried by different victims or volunteers in post-disaster scenario. Volunteers may use this DTN to relay sensitive situational data. However, in such fragile network environment, some malicious nodes may try to intercept, manipulate data with the intention of corruption and fraud. Furthermore, an adversary node may compel a trusted node to compromise its security credentials or may physically capture the node. As a result, attackers get the authority to sign any message on behalf of the compromised node and can launch various attacks to perturb the network. To combat these attacks, we envision a compromise-tolerant DTN, where time-varying pseudonyms are used to obscure the actual identity and safeguard the privacy of genuine nodes. Unique implicit session key agreement facilitates the establishment of credential-free secure communication session between two legitimate nodes and protects the data from being revealed to the adversaries. Periodic certificate revocation scheme restricts use of any compromised credentials beyond a certain time. We evaluate iSecure scheme using ONE simulator to understand feasibility, performance and overhead.
