Nowadays the recommender system has grown in social media, mobile devices, personal use, and etc. on the internet every site has used the recommender system to attract the users or improve the site uses. But the existing recommender system has less accuracy, less recommendation speed and insufficient support to the current environment. To solve this problem, we propose the Hybrid MI technique which is based on existing MI technique. The existing MI technique is insufficient in speed, accuracy, and support, to solve this issue we proposed Hybrid MI technique. The existing methods failed to achieve accuracy, flexibility and early recommendations. These problems are overcome by a recently presented method called MI which is recommendation system extending ROSE. But the limitation of MI is that no end user satisfaction is taken into the considerations, and hence there is always scope for improvement in accuracy. In this project we are presenting HMI (Hybrid MI) technique in which we are improving the accuracy by relevance feedback method, in which log of feedbacks should be maintained and based on end users feedbacks, the proposed system can refine and regenerate more accurate recommendations next time for the same query with less time.

The problem of seismic protection from the main types of surface acoustic waves and shear-pressure (SP) evanescent waves emanating from vicinity of an epicenter of an earthquake is discussed. Herein, SP waves represent a kind of the evanescent waves arising at critical angles of incident of bulk shear waves. The proposed seismic protection method utilizes vertical trenches (vertical barriers) filled with the specially constructed granular metamaterials. Some of nonlinear hyperelastic models along with nonlinear and inelastic models are analyzed for applications using granular metamaterials in case of cyclic dynamic loadings that correspond to arrival of the large intensity surface acoustic and evanescent waves. The main attention is paid to arrival of the large intensity Rayleigh, Rayleigh-Lamb and SP waves, as the most frequent waves and the most dangerous waves for engineering structures. Some of the new constitutive equations for metamaterials exhibiting different elastic moduli at tension and compression phases are proposed and discussed. © Published under licence by IOP Publishing Ltd.

Approximate circuits have been developed to provide good tradeoffs between power consumption and quality of service in error resilient applications such as hardware accelerators of deep neural networks (DNN). In order to accelerate the approximate circuit design process and to support a fair benchmarking of circuit approximation methods, libraries of approximate circuits have been introduced. For example, EvoApprox8b contains hundreds of 8-bit approximate adders and multipliers. By means of genetic programming we generated an extended version of the library in which thousands of 8- to 128-bit approximate arithmetic circuits are included. These circuits form Pareto fronts with respect to several error metrics, power consumption and other circuit parameters. In our case study we show how a large set of approximate multipliers can be used to perform a resilience analysis of a hardware accelerator of ResNet DNN and to select the most suitable approximate multiplier for a given application. Results are reported for various instances of the ResNet DNN trained on CIFAR-10 benchmark problem.

Remodeling involves the transition from existing models of the given system to the models of some other class that reveals possibilities for overcoming research difficulties. Takagi-Sugeno (T-S) fuzzy models provide an established approach to description, analysis and synthesis of nonlinear systems. However the potential of transition to fuzzy description on the basis of T-S models is not fully understood and implemented in analysis and synthesis of nonlinear systems. The paper uncovers the peculiarities of the approach to nonlinear system remodeling based on T-S fuzzy models. It demonstrates the scheme of fuzzy remodeling that allows replacing the initial model of the nonlinear system by the T-S fuzzy model equivalent to it in a bounded area of the phase space. The examples illustrating the range of approach applications are given. It is shown that the transition from a nonlinear model to a T-S fuzzy one enables us to solve various analysis and control tasks via the implementation of the apparatus of linear matrix inequalities. The sources of conservatism of fuzzy remodeling, that lie in peculiarities of T-S fuzzy models are emphasized. © 2020 IEEE.

The profitability of the livestock industry largely depends on cost-effective feed formula as feed accounts for a large proportion of production costs. Recently, it is one of research hotspots that investigation on how to scientifically formulate livestock feed reducing the cost. In this work, an Improved Tabu Search (ITS) algorithm is proposed to study the pig feed formula optimization method. The proposed ITS algorithm focuses on combination of the tabu search algorithm and intelligent optimization algorithms, which can obtain advantages of global and local optimization search from traditional optimization algorithms. The experimental results show that the ITS algorithm can achieve higher precision search and performs better than other optimization algorithms. © 2021, Springer Nature Singapore Pte Ltd.

nonlinear least squares type iterative solver for f(x)= 0 is considered based on successive solution of orthogonal projections of the linearized equation on a sequence of appropriately chosen lowdimensional subspaces. The bases of the latter are constructed using only the first-order derivatives of the function. The techniques based on the concept of the limiting stepsize along normalized direction (developed earlier by the author) is used to guarantee the monotone decrease of the nonlinear residual norm. The results of numerical testing are presented, including not only small-sized standard test problems, but also larger and harder examples, such as algebraic problems associated with canonical decomposition of dense and sparse 3D tensors as well as finite-difference discretizations of 2D nonlinear boundary problems for 2nd order partial differential equations.

This paper explores a comprehensive study at the application of second harmonic generation in low power laser generation by introducing electro-optically adjustable nonlinear phase shift inside a LiNbO3 crystal. Research on electro-optically adjustable nonlinear phase shift in high power laser generation is completed already by way of the usage of special crystals having higher electro-optic coefficients and higher damage threshold. However, crystal having lower damage threshold can withal be habituated to create this mentioned phenomenon if having better electro-optic coefficients. Hence, on this paper the advanced traits of LiNbO3 like higher electro-optic coefficients and lower damage threshold that makes this crystal very much handy to increase cascaded nonlinearity in low power laser generation are proposed. As consistent with our theoretical analysis, the propagating fundamental wave is oscillating at 1064 nm parallel to y-axis of the crystal having crystal cut at \theta=67.14737{\circ} and \phi=90^{\circ} in phase matching direction. A analytical voltage of ±2.5 kV is applied across the crystal's thickness of 5 mm along z-axis of the crystal that creates the phase shift in between the incident and reconveretd fundamental waves which is nonlinear in nature. This nonlinear phase shift can be facilely tuned from maximum to minimum value by adjusting the applied external electric field. © 2020 IEEE.
