In this paper, we propose a modified extra-gradient method (MEGM) for solving quadratic optimization. In the MEGM method, we use a matrix parameter G k to balance the primal and dual variables. Numerical results show that the MEGM method significantly improves both computational cost and iteration number compared to the classical extra-gradient method.

Achieving network throughput maximization through power control has been a long standing open problem in interference-limited wireless networks. Firstly, we introduce the wireless channel propagation model. Secondly, basing on the model we put forward a compensation power control method named CPCMID (A Compensating Power Control Method Based on Interference Detection), which triggers the power control process by computing the network interference. The experiments results show that CPCMID is effective to reduce the shock of the network, and can get better network performance and convergence effects.
So far, the genetic algorithm has been presented for the energy-aware scheduling of virtual machines to minimize the total busy time of servers. However, this algorithm does not consider the criteria for service-level...

The Sanskrit Encyclopaedic Dictionary conceived and compiled by Deccan College Post Graduate Institute, Pune, India is available in paper format. For greater reach, there is a need for digitization of the dictionaries and conversion of these volumes into a comprehensive structured database. These volumes have Articles with a typical complex structure. In this paper, a novel approach for Automatic Lexical Element Extraction from Sanskrit Encyclopaedic Dictionary Pages (ALEE-SED) that consists of Sanskrit Dictionary Page Segmentation into articles and their meaning blocks using Optical Character Recognition (OCR) and Detectron2 Model further followed by an intelligent article wise dictionary (Lexical) element extraction is described.

In this paper we have presented a new variant of diversity guided PSO algorithm named QIPSO for solving global optimization problems. The QIPSO algorithm makes use of a quadratic crossover operator to maintain the level of diversity in the swarm population, thereby maintaining a good balance between the exploration and exploitation phenomena and preventing premature convergence. We have compared it with Basic Particle Swarm Optimization (BPSO) and another diversity guided PSO called ARPSO. The numerical results show that QIPSO outperforms the other two algorithms in all the seventeen cases taken in this study.

In recent years, the development of intelligent cabins has been rapid, but testing and evaluation usually involves detecting a single component, lacking a quantitative evaluation method for the overall performance of intelligent cabins. To address this issue, firstly, study the visual interaction elements inside the cabin and summarize the visual interaction testing methods; Then, research auditory interaction testing methods and establish a noise library to achieve reproducible experiments on common external environments; Finally, establish a multi-dimensional comprehensive evaluation method for the intelligent cabin to achieve a comprehensive evaluation of the overall performance of the intelligent cabin.
Visual Place Recognition (VPR) techniques commonly utilize Contrastive Losses (CL) to train models that generate compact and discriminative global descriptors for images. These models often result in poor performance ...

In Peer-to-Peer (P2P) multi-channel live streaming, helper peers with surplus bandwidth resources act as micro-servers to compensate the server deficiencies in balancing the resources between different channel overlays. With deployment of helper level between server and peers, optimizing the user/helper topology becomes a challenging task since applying well-known reciprocity-based choking algorithms is impossible due to the one-directional nature of video streaming from helpers to users. Because of selfish behavior of peers and lack of central authority among them, selection of helpers requires coordination. In this paper, we design a distributed online helper selection mechanism which is adaptable to supply and demand pattern of various video channels. Our solution for strategic peers' exploitation from the shared resources of helpers is to guarantee the convergence to correlated equilibria (CE) among the helper selection strategies. Online convergence to the set of CE is achieved through the regret-tracking algorithm which tracks the equilibrium in the presence of stochastic dynamics of helpers' bandwidth. The resulting CE can help us select proper cooperation policies. Simulation results demonstrate that our algorithm achieves good convergence, load distribution on helpers and sustainable streaming rates for peers.

This paper predicts the presence of the limit cycle for a class of nonlinear fractional-order feedback control plants with separable nonlinearities. The concept of describing function along with the Nyquist contour is extended to evaluate the amplitude and frequency of such periodic oscillations for a fractional-order time-delay system. The critical value of plant gain is evaluated below which the system response shows convergence and oscillations fail to sustain. The accuracy of the proposed technique has been substantiated by comparing it with the results from MATLAB/SIMULINK applications.
