We propose a texture synthesis image inpainting method that minimizes energy function with the filling order which facilitates propagation of edge from the data region to the target region. As a result, the proposed method provides plausible restoration while propagating information of edge for the target region. Experimental results show the validity of the proposed method.

Priorities of digital industry have changed over decades. Now-a-days nanotechnology grasp the major attention of digital industry. Quantum dot Cellular Automata(QCA) came out to be an efficient nanotechnology which can replace existing technologies in nanoscale. One of the well studied and researched variant of QCA is 4 Dot 2 Electron QCA. In the present scope our complete focus will be on 2 Dot 1 Electron QCA which is an emerging variant of QCA. This paper presents an improved design strategy of Ex-OR gate using 2 Dot 1 Elecron Quantum Cellular Automata(QCA) which consists of only 23 many 2 Dot 1 Electron QCA cells. The proposed design reduces the number of cells in comparison to the existing Ex-OR gate design in [1]. The proposed design of the EX-OR gate not only ensures high degree of compactness but also a huge reduction in the amount of required energy. This design strategy reduces the energy requirement as well as energy dissipation both upto 15 percent. The proposed Ex-OR gate implementation achieves upto 95.83 percent of compactness which is nothing but an index of area utilization. This design methodology of Ex-OR gate can be utilized to design multiple digital logic circuits. In our present perview we use the Ex-OR gate design to implement different reversible logic gates such as Tofolli gate and Feynman gate. We also suggest the design methodology of the Fredkin gate which is a reversible gate. To the best of our knowledge the designs of reversible gates using 2 Dot 1 Electron QCA have not been reported in literature yet. The proposed designs are analyzed with respect to different energy parameters.

Quantum-Dot Cellular Automata (QCA) is coming to the forefront in the nanotechnology domain as it overcomes the serious technical limitations of CMOS technology. Here, using two-dimensional two-dot one-electron QCA cells we have designed a logically reversible half adder. Such half adders in pair are used to design a full adder. We have computed the potential energies to substantiate and analyse the proposed design and discussed the issues related to energy and power dissipation.

Medium-Voltage capacitor banks are widely used in distribution network applications such as power-factor correction, reducing energy consumption and power losses. However, using a switched capacitor bank can generate excessive transients to the electrical system. In this paper, the transients following the energization and de-energization of a capacitor bank are obtained using frequency dependent models of the distribution network. Furthermore, a detailed breaker model is employed to enhance the accuracy of the results since the effects of restrikes or prestrikes can wear the contacts of breaker leading to failure. Finally, a recently proposed diode based transient limiter is modeled to study its effectiveness on limiting the switching transients and its ability in eliminating risk of failure in the bank and its associated circuit breaker.

This paper proposes a model predictive control (MPC) approach for discrete-time jump Markov linear systems (JMLS) considering constraints on the inputs as well as on the expectancy of the states. Prediction equations for the first moment of the states are formulated, in which the dependencies on the inputs, on the expected values of disturbances, and on the current states are directly considered. For the computation of the matrices needed for predicting the first moment of the states, a recursive algorithm is presented. Finally, the prediction equations are used to formulate the MPC problem as a quadratic program (QP). Due to the recursive structure of the prediction equations and the formulation as a QP, the computational effort is low compared to existing approaches. Simulation results demonstrate the properties of the presented MPC approach and its capabilities of controlling large-scale JMLS online.

Distributed File system was widely used as a cloud computing backend storage with high scalability,low cost,and reasonable sequential I/O *** I/O workload is mostly composed of small random I/O and distributed file system does not have enough performance for this I/O *** for this gap,we applied a cache using memory and SSD(Solid State Drive) to distributed file *** cache was implemented in the file system's client *** uses memory as write cache and SSD as read cache with write-back policy for minimizing the I/O response *** distributed file system was implemented on user-level using Fuse(File system in User space) *** the client-side cache was used,the file server which previously could not support even 1024 users was improved enough to support more than 3000 *** applying the client-side cache,it is possible to solve the performance drawback of the distributed file system used for VDI storage.

In this paper, the accuracy of soft computing technique in solar radiation prediction based on series of measured meteorological data (monthly mean sunshine duration, monthly mean maximum and minimum temperature) taking from Iseyin meteorological station in Nigeria was examined. The process, which simulates the solar radiation with support vector regression (SVR), was constructed. The inputs were monthly mean maximum temperature (Tmax), monthly mean minimum temperature (Tmin) and monthly mean sunshine duration ( $$ \bar{n} $$ ). Polynomial and radial basis functions (RBF) are applied as the SVR kernel function to estimate solar radiation. According to the results, a greater improvement in estimation accuracy can be achieved through the SVR with polynomial basis function compared to RBF. The SVR coefficient of determination R 2 with the polynomial function was 0.7395 and with the radial basis function, the R 2 was 0.5877.
