Based on a sorting network, the proposed approximate median filters (APMF) produce acceptable image quality on low-cost hardware. A specialized comparator is being developed to increase the noise-elimination capabilities of such filters. The inexact median filters (IMF) have a regular and modular architecture. Further, to reduce the power consumed by digital systems clock gating is employed. Clock with a View Into the Future Gating is a unique way of computing each FF's clock enabling signals one cycle ahead of time, based on the current cycle data of the FFs it depends on. By allocating a whole clock cycle for the computation of the enabling signals and their propagation, it avoids the strict timing constraints of adaptive geometric features-based filtering (AGFF) and data-driven. In addition, to give a better assessment of intrinsic mode filter (IMF) performance, a novel error evaluation approach based on a histogram-based error dispersion plot was presented. The proposed filter is effective in terms of power, area, and speed, according to simulation findings. The filter's output quality is comparable to that of a precise filter, despite the trade- off between filtering precision and circuit features. In addition, the deterioration is almost unnoticeable to the naked eye. When the clock power is reduced, the entire system's power is reduced as well.

Adhoc networks are becoming a new wireless networking technology built for mobile hosts that are becoming more popular. Instead of relying on fixed infrastructure, ad hoc networks, as opposed to standard mobile wireless networks, are completely mobile. In this paper, we introduce a security mechanism in which packets are encoded and decoded using an arbitrary method selection scheme. The recommended model's functionality is assessed, and it is discovered that there was no reduction in control overhead, however a little delay has been introduced as a result of the authentication approach. Our outcome is that the recommended security architecture will function well for heavily loaded systems with a high mobility and that it may be updated to include other cryptographic algorithms in future versions. Ultimately, the quantitative analysis is carried out, where for the instance of length of the character set to 100; the suggested modified SFO ultimately outperformed to those already in use, with cost function being 22 % significantly greater than available PSO, 20% significantly bigger than available GWO, 19% significantly greater than available WOA as well as 21 % bigger than available SFO. The comparison study with conventional models confirms the suggested model's gives effective performance in terms of dissimilar analysis.

Air pollution, Asthma, and Gross Domestic Product (GDP) are very important indicators to human life and development and it has been found that air pollution has a big effect on the latter two. In this paper, we find the correlation factor and to what extent air pollution has an effect on those two. For this, we chose 20 American states, handpicked the ones having unique features with respect to pollution levels, asthma cases, GDP numbers, and the datasets for the past 20 years of each state were taken. We chose 6 toxic pollutants, namely PM2.5, Carbon Monoxide, Sulfur Dioxide, PM10, Ozone, and Nitrogen Dioxide with each dataset including daily readings of these pollutants for the past 20 years in each state. The idea behind our model is to use all these data and find the extent to which air pollution is related to the asthma cases and the GDP of a state. For this, we use 4 models, namely Neural Network (NN), Random Forest (RFC), Support Vector Machines (SVM) and K-Nearest Neighbors (KNN). We use metrics like Root Mean Square Error (RMSE), Mean Absolute Error (MAE) and R-Squared to evaluate our results. We observed a positive correlation between rates of asthma and GDP and pollution data. NN gave the best prediction accuracy especially for GDP (Average: 76%) followed closely by SVM. SVM's also had the least MAE while RFC had the least RMSE.

The pandemic situation has greatly affected normal working in various sectors. One of the affected sectors is education. Due to online meeting platforms, there was not much difficulty in conducting theory classes. But the real challenge was conducting the lab classes and exams. We take up the problem of conducting computer programming assessment in online mode. One may argue that computer systems and handheld devices are common nowadays, and there are not many hurdles in handling lab sessions. But conducting a fair assessment is a challenging task. We propose a novel virtual platform with monitoring features to facilitate a smooth assessment. Our platform detects the student's face and verifies if there is any proxy. Further, the platform sends the student's image to the examiner for verification. Our platform detects the number of faces within the camera frame. We include modules to detect if the student uses a mobile phone during the examination. The trained model will be deployed in tensorflow workspace which can be easily integrated into the platform as an API and we have verified the efficiency of the model. We observe a 1.47 loss value, which shows the efficiency and feasibility of our proposed model.

Wearable and implantable medical devices are revolutionizing health-care today with lab-on-a-chip technologies because they can register a wide range of physiological and environmental parameters. Implantable Medical Devices (IMDs) and Wearable Medical Devices (WMDs) with bio-sensors have modernized the way high-quality, safe health care is delivered. The wearable device is more readily available than IMDs and does not require additional installation expenditures. It is critical to find solutions for battery depletion, resolution, and data prevention in Wearable Medical Devices (WMDs). The purpose of this paper is to provide a strategy for overcoming current wearable technology challenges. SAR-ADC has a flexible binary search approach, good power efficiency, and high resolution, and the recommended system aids in wearable sensor node reconfigurability. Wearable Medical Devices could generate medical data and communicate it via wireless networks to a cloud-based system. During the data transfer to the cloud, the Man in the Middle will steal confidential medical information. Advanced Encryption Standard (AES) methods are active in Wireless Sensor Networks (WSNs) to safety net the data from loss or stealing of data. AES is a hardware-based encryption method that safeguards data from a variety of threats. As a result, the suggested system uses the AES algorithm to transform data that un-encrypted into encrypted data. The 128 bit AES algorithm was used with the XILINX 14.5 software, yielding a result of 7.528 ns minimum time and 296.8MHz frequency, with a throughput of 1.70 GB/s.

Breaks down boundaries and inspires creativity. These are just a few examples of how communication affects the world around us. Many successful people use this tremendous tool of communication to change the world, while others with disabilities in speech, hearing, or having multiple disabilities use sign language to change the world. However, the disadvantage of employing sign language is that not everyone would be able to understand it. To address this issue, a sensor-based system is proposed with five flex sensors put on five fingers as binary bits, yielding a total of 32 options in this study. In addition, this proposal includes two options for broadening the reach of terms. This proposed model eliminates the need for other types of sensors besides flex sensors, lowering production costs significantly. It is more accurate and efficient than vision-based approaches because it is sensor-based. Because of this project, people who do not understand sign language can communicate easily with people who have speech or hearing problems.

Non-Orthogonal Multiple Access (NOMA) is one of the upsurging technologies for the Beyond 5G communication network that finds application in M2M, V2V, and connecting low-power IoT devices. NOMA exploits the multiplexing of signals in the power domain but with the same frequency. The conventional multiple access scheme is Orthogonal Multiple Access (OMA), whose performance is far less efficient when compared to NOMA. Fairness Index (FI) is one of the performance metrics that analyzes the quality of service offered by NOMA and OMA systems. In this paper, the Jain's Fairness Index (JFI) of the NOMA and OMA systems are analyzed with two users and then with more users. For the available bandwidth of 20 MHz with five users, the FI for NOMA is 0.9058, and that for OMA is 0.7087, ensuring the possibility of massive connections with the NOMA system.

Augmented Reality (AR) is a young area that is rapidly developing. Its goal is to bring the virtual and real worlds together. By incorporating virtual things into our view of the actual world, AR aims to improve our experience of it. This paper introduces a new gesture controlled AR system, which performs hand gesture recognition using novel acquisition devices such as the Leap Motion and Kinect sensors. And using these devices, it is feasible to collect a highly thorough description of the hand posture, which is used to identify exact gestures. To recognize the executed gestures, an ad-hoc feature set based on the location and orientation of the fingertips is generated and inputted into a Random Forest classifier. In order to increase recognition performance, a collection of features is taken from the depth computed by the Kinect and coupled with the Leap Motion ones and a recognition rate around 81 % is achieved. And those gestures are interfaced with the Unity 3D in order to implement a hand gesture based human machine interaction system.

A stacked microstrip patch antenna using a microstrip feed line for UWB functions has been proposed in this paper. By using two different substrate for assigning the property of stack FR4 and Rogers RT/duroid 5880 with a dielectric constant (εr) of 4.4 and 2.2, respectively, with a gap of 1.5 mm, is assigned. Overall antenna dimensions are 27 mm × 30 mm × 4.7 mm. The concept of EM coupling means that the conduction occurs so that proper matching is desired in this antenna. Multiple slots increase the flow of conductivity in different regions. The simulated results show the bandwidth (B.W) obtained at 3.34 - 4.42 GHz, 6.0012.56GHz GHz with a gain ranging from 4.5 to 8 dB. Throughout this entire region, the proposed antenna provides $mathrm{S}_{11} < -10$ dB.

The wireless communication field is growing tremendously. To achieve the key requirements of future wireless networks, reconfigurable intelligent surface (RIS) assisted communication is a new research direction. RIS consists of more passive reflectors, and it can direct the signal towards the desired user by adjusting the phase shift of passive elements, hence signal-to-noise ratio (SNR) can be improved. The ideal RIS can compensate the channel effects completely. Practically, the compensation of each and every phase of RIS elements is very difficult. In this work, an algorithm for intelligent discrete phase shifter assisted RIS is developed. The proposed algorithm is tested with one-bit and two-bit discrete phase shifters. Discrete phase shifter maps the required phase of RIS elements to discrete phase levels and steers the beam. Through simulations, it is observed that the increase in discrete phase levels and RIS elements offers performance similar to ideal RIS assisted communication.
