In this article, a nonlinear active control technique is proposed so as to attain the synchronization of two different chaotic systems. Master and slave configuration is incorporated for the analysis. The main objective is to design Reduced Order Synchronization (ROS) scheme, where the order of the master system is greater than that of the slave system. Initially, active control technique based ROS is achieved and after that the results are extended to address reduced order synchronization in the presence of time delays in the systems. Based on Routh-Hurwitz criterion and Lyapunov stability theorem, the convergent behaviour of the error dynamics is proved. The theoretical results are validated by the detailed simulation results for Lorenz-Stenflo and Lü system.

In this paper, a method is proposed to denoise image based on semi-adaptive conductance function in anisotropic diffusion filter and bi-dimensional empirical mode decomposition. Here, the color image is utilized in the work to split the image into red, green and blue channels. To each channel component, the local difference value method is implemented where the noise contaminated pixels of the respective channel are replaced with the processed ones in which a Gaussian filter is used for smoothing. The bi-dimensional empirical mode decomposition decomposes the channel into its constituent intrinsic mode functions and the diffusion filter is applied to them. The various function parameters define the extent of diffusion to the channel like connectivity, conductance function, number of iterations and gradient threshold. Here, the conductance function is made semi-adaptive by introducing the gradient value of the image to the threshold parameter along with a preset constant term. The processed intrinsic mode functions, obtained by applying the modified diffusion filter in the conductance function, of each channel are combined and the final image is reconstructed by merging all the three channels. The experimented results thus obtained are evaluated and compared with other existing techniques based on the performance parameters like peak signal-to-noise ratio, mean square error and, structural similarity index and concluded that the proposed method is superior and efficient in both image denoising and feature retention.

Electrical energy increases its vast area day by day. Just like water it becomes necessary to save power for betterment of our future. So, an idea came into our minds why not we develop a technique for reducing the power demand by making corridor's lights efficient. In this documentation we discuss the experiment which was implemented in Electrical Engineering department's corridor of Rajkiya Engineering College Ambedkar Nagar, Uttar Pradesh, India. The main purpose of this experiment is to reduce the power consumption and make corridor lighting system to be more efficient. These experiments are mostly based on our observations that mainly college's corridor is used when the class period is going on and human movements during these period and the remaining time corridors are empty but the lights in corridor is always turn ON till the college is not over. To dealing this problem we use PIR (Passive Infrared) motion Sensor. PIR sensor is low-cost device and helps to minimizes the electricity bill. Finally, after implementation of this experiment we found drastic change in power consumption and it reduced by 77.78%.

Coronavirus disease 2019 (COVID-19) is a contagious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which has spread worldwide, creating an unprecedented pandemic situation. Due to rapid spreading, the pandemic forced several nations to impose lockdown for isolating the population and new policies of quarantine were adopted. After the government eased the restrictions, the most prominent challenges faced by daily commuters (employees or students) include maintaining a safe distance from others, regular sanitization, and washing hands, wearing masks and face shields, contact tracing, etc. It is quite difficult to practice social distancing and always use hand sanitizer when using public transport or at the workplace and people do not have a track of their temperature, heart rate, and oxygen saturation level. Though it is ideal to avoid traveling, when necessary some factors need to be considered such as personal hygiene, contactless interaction, disinfection, and monitoring important health parameters. Given this, we aim to develop an IoT-enabled compact wearable system including all essential features like an electronic face mask, an automatic sanitizer dispenser, and a Temperature-SpO2 monitoring wearable to avoid any physical touch and discomfort and alert the nearby doctors about irregularity in any parameter through the GSM module. The results of the software simulation of the system and the web-scraping using Python software to extract coordinates of containment zones are discussed in the paper.

In this work, a new approach lean on minor component analysis (MCA) neural learning and fractional derivative (FD) is introduced for the design of digital finite impulse response (FIR) filters. In this method, design problem is modeled as summation of integral error in passband and stopband region in term of polyphase components (PCs) of a FIR filter in frequency domain, which is solved by an efficient machine learning algorithm called minor component analysis (MCA) neural learning. For more accurate frequency response, fractional derivative is applied at a reference point in passband, and the resulted fractional derivative constraints (FDCs) are optimized by particle swarm based techniques, using an objective function formulated as summation of maximum error in pass band and stop band region and stopband attenuation (in magnitude) of a FIR filter. The comparative study with recently published results evidence the impact of proposed method.

Efficient routing with 100% survivability level is one of the challenging task for wavelength division multiplexing (WDM) optical networks. In this paper, we have proposed an efficient cluster based protection (CBP) strategy to improve the survivability in WDM optical networks. CBP strategy provides protection against a single link failure. In CBP, the connection requests are classified into different clusters. The requests having link-disjoint primary paths are considered in the same cluster. Each cluster is processed one by one as per the decreasing order of cluster size or the number of requests in a cluster. Simulation results of the proposed CBP strategy shows improved performance on the evaluating parameter of blocking probability (BP), resource overbuild (RO) and link load (LL) in comparison to the traditional shared path protection (SPP) strategy. CBP strategy shows 16.51 % and 12.57 % reduction in BP and RO, respectively. Also, the CBP distributes traffic load uniformly along each link of the network which is demonstrated by LL metric.

Solar energy is one of the most important non-conventional resources that can be used to produce electric energy through the solar photovoltaic process. A powerful advantage of solar photovoltaic (PV) systems is the use of comfortable and free energy from the sun. The characteristic of photovoltaic cell/array/module solar systems is necessary to gain a good show of structure under various conditions. The characteristics permit the simulation of photovoltaic cell/array/module systems that receive various solar temperatures and illumination levels. The solar array for a PV array turns on the unspecified variable, sometimes they turn on meteorological. This research paper expands the algebraic model in MATLAB/ Simulink environment of solar PV array system and plots different characteristics like Io - VO, Po-Vo, and Po- Io of solar array photovoltaic cell/array/module System

Partial shading has degrading effects on output productivity of the photovoltaic (PV) arrays that can be mitigated by various techniques for altering the connections of the PV modules. This paper proposes a technique to diminish the effects of shadowing on PV systems and to achieve greater global power maxima (GMPP) with the help of puzzle theory-based approaches such as the proposed algorithm to design a 6×6 size array. An investigation into the traditional electrical arrangements, e.g., Series-parallel (SP) and Total-cross-tied (TCT), is compared with in this paper. In addition, the proposed algorithm is helpful to arrange PV modules for enhancement power maxima values during non-uniform irradiation levels. MATLAB/Simulink based results are analyzed in terms of power loss (PL) and fill factor (FF). Critical observation carries the burden of showing the effective outcomes of the proposed PV array arrangement. The present paper is useful for academicians and researchers working to find new methods to decrease the partial shadowing effect on PV arrays to secure higher GMPP locations.

In the biomedical field, electrocardiogram (ECG) recording produces a large amount of data, which are stored in a digitized format for monitoring and diagnosis purposes. In this regard, it is essential to reduce data size due to memory constraints in ambulatory and tel-e-medicine systems. This paper proposes an algorithm using optimized tunable-Q wavelet transform (TQWT) to reduce the memory requirement. It has the flexibility to tune its parameters to obtain the desired compression. For optimizing the parameters of TQWT, nature-inspired algorithm ant colony optimization (ACO) is used. The compression is achieved by using a dead-zone quantizer (DZQ) and run-length encoding (RLE). Results illustrate that significant compression has been achieved at the cost of acceptable distortion in the signal quality. The performance of the proposed technique is evaluated using percentage-root-mean square difference (PRD), compression ratio (CR), and quality score (QS). The average value obtained of CR, PRD, and QS are given as 22.42, 4.52%, and 6.05, respectively.

In this paper design of fractional order controller for stable systems based on the IMC approach is presented. The proposed method creates a filter internally; therefore, phase lag obtained by an external filter in the system response can be avoided with the proposed method. It has the capacity to regulate the transient response and robustness of the system with a single parameter. This parameter plays a vital role to obtain the optimum response. Hence, a metaheuristic algorithm is considered. Numerous performance parameters and performance are considered to examine the proposed methodology efficacy. The proposed methodology performance has been carried out under load disturbance, robustness analysis. Also, its performance has been compared with various existing techniques.
