Abstract

One way of communicating with the deaf is to speak sign language. The chief barrier to little Indian sign language (ISL) research was the language diversity and variations in place. It is essential to learn sign language to communicate with them. Most learning takes place in peer groups. There are very few materials available for teaching signs. Thus, signing is very challenging to learn. Fingerspelling is the first step in sign learning and is used whenever there is no appropriate sign or if the signatory is unfamiliar with it. Sign language learning tools currently available use expensive external sensors. Through this project, we will take this field further by collecting a dataset and extracting functionally helpful information used in several supervised learning methods. Our current work presents four validated fold cross results for multiple approaches. The difference from the previous work is that we used different figures for our validation set than the training set in four-fold cross-validations.

Abstract

Designing with cultural, wisdom, way of life, beliefs, and other values that have been passed down through generations. Let's produce a creative product that is entertaining and varied. One of them is to design a mascot to be used in the media as a character and representation of something, and to imply that this mascot will be able to act on behalf of those representatives. It is clear that Phuket has an exceptional and valuable cultural capital. In addition, there are numerous traditions, rituals, beliefs, customs, arts, and civilizations that are indigenous to the local population. It was thought that this study did a good job of figuring out how to use cultural values to make characters by applying design theory or design science to creativity. It also did a good job of figuring out how applicable the methods and design approaches were.

Abstract

Systematic design for testability (DFT) is a technique to enhance the testability of design so that it is further organized and self-regulating. The objective of systematic DFT is to enhance a circuit's operability and evidence. This can be performed in a variety of ways. The scan pattern method is the extremely predominant, and it modifies the design's internal sequential circuitry. In this manuscript, frequently used industry standard functional register-transfer level (RTL) designs are chosen. Structured DFT approach is adopted to do scan insertion and automatic test pattern generation (ATPG) to enhance the testability. Proposed methodology provides the controllability and observability for the clocks and reset used in chosen RTL designs by eliminating S rule and D rule violations by adding test logic. Also able to insert stuck at faults and achieve fault coverage of 97.78% and test coverage of 99.26% for DFT architecture for Wallace tree multiplier design, and found different classes of faults as testable and untestable faults and also performed fault simulation for the intended designs to detect fault from the created deterministic patterns.

Abstract

Business process modeling (BPM) is a field of computer science that can be used by every organization to maintain its workflow pattern. Adopting this can significantly improve the workflow and can identify problems with the workflow in terms of resource optimization. In this article, the idea of representing the business processes of a Bangladeshi Educational Institute using the business process model and Notation 2.0 has been presented. In this case study, a business process model for the information system at the departmental level of East West University (EWU) has been designed after analyzing 15 key business processes by interviewing stakeholders. After classifying the created as-is business process models based on two criteria- order of actor participation and participation of external entities/departments, two areas of optimization in the workflow pattern have been proposed, load optimization and online automation. This documented model of the business processes has multi-purpose uses. It can be used for resource management, as a guide for stakeholders to better understand a business process, and as a guideline for new employees. This study has shown that by adopting business process modeling, an educational institution could march toward a better and enhanced workflow pattern by identifying problems in it.

Abstract

Whale optimization algorithm (WOA) is an emerging nature-inspired, swarm-intelligence based algorithm to solve optimization problems more efficiently. This algorithm is based on the bubble-net hunting strategy of the humpback whales. It has gained immense popularity among researchers, typically, due to its simple nature, fast convergence, and having minimum parameters. In the recent past, it has been widely adopted in various fields including data mining, machine learning, wireless sensor networks, cloud computing, civil engineering, and power systems due to its optimal performance. The WOA has given competitive results in comparison to the state-of-the-art optimization algorithms. In this study, we aim to present a comprehensive survey of WOA consisting of more than eighty existing variants of WOA. More specifically, we intend to put forward key aspects of WOA variants with reference to modifications and applications. Further, we classify the most dominant variants of WOA in distinct categories based on modification area such as equation modification, parameter tuning or the problem space for which an algorithm has been specifically altered. We believe that this study will be beneficial for the community working on optimization problems and it can serve as a basis for understanding the modification and improvement process of an optimization algorithm.

Abstract

The support vector machine (SVM), one of the most effective learning algorithms, has many real-world applications. The kernel type and its parameters have a significant impact on the SVM algorithm's effectiveness and performance. In machine learning, choosing the feature subset is a crucial step, especially when working with high-dimensional data sets. These crucial criteria were treated independently in the majority of earlier studies. In this research, we suggest a hybrid strategy based on the Harris Hawk optimization (HHO) algorithm. HHO is one of the lately suggested metaheuristic algorithms that has been demonstrated to be used more efficiently in facing some optimization problems. The suggested method optimizes the SVM model parameters while also locating the optimal features subset. We ran the proposed approach HHO-SVM on real biomedical datasets with 17 types of cancer for Iraqi patients in 2010-2012. The experimental results demonstrate the supremacy of the proposed HHO-SVM in terms of three performance metrics: feature selection accuracy, runtime, and number of selected features. The suggested method is contrasted with four well-known algorithms for verification: firefly (FF) algorithm, genetic algorithm (GA), grasshopper optimization algorithm (GOA), and particle swarm algorithm (PSO). The implementation of the proposed HHO-SVM approach reveals 99.967% average accuracy.

Abstract

The performance of every electrical system depends on the different electrical devices especially transformers. Petroleum-based mineral oil is widely used for insulation and cooling purpose. The disadvantage of mineral oil is its low biodegradability and is a major threat to the ecosystem due to its poor oxidative stability. To remedy the drawbacks, focus on alternative fluids that can replace traditional mineral oil. Alternative liquids such as natural esters are used which do not panic the ecosystem. With the support of additives in natural esters liquids, the productivity of the oil can be increased, paving the path for the green conversion of liquids in high voltage applications. The purpose of this article is to analyze the electrical properties of the newly developed indigenous oil. The inhibited oil was insulating oil to which antioxidants were added such as 2,6-ditertiary-butylparacresol, butylated hydroxyl anisole and tertiary butyl hydro qunine to slow down the oxidation rate and to check the electrical properties. This article discusses the electrical properties of mineral oil, developed indigenous oil with and without antioxidants as per IEC62770 standards. A 1.1 kVA transformer was then designed in a laboratory for load tests and Indigenous oil performance under load was evaluated.

Abstract

Reserve the wireless sensor networks (WSNs) lifetime for as long as possible is a current goal. In WSNs, sensors are often limited in power. However, uneven power consumption (UPC) reduces lifetime, and its deterioration is considered one of the most critical problems. Therefore, balancing the energy consumption is a significant issue in the WSN, necessitating a routing protocol that is energy-efficient that extends the life of the network. A few protocols have been used to balance energy use across network nodes. This paper proposed a routing protocol energy-saving called Bacterial foraging optimization routing protocol (BFORP). BFORP attempts to investigate the problem of the life of WSNs. It can decrease the routing of excessive messages that may result in severe energy waste by recycling the information that frequents the source node into the sink. In the proposed method, the preferable node in the sending routes may be chosen by prioritizing the lowest traffic load, the highest residual energy, and the shortest path to the sink. In comparison to the known protocols used in routing, the results of the simulation have proven the efficacy of the suggested protocol in lowering energy employment and reducing the delay of end-to-end.

Abstract

This paper develops a maximum power point tracking (MPPT) approach for a microgrid-linked solar photovoltaic (PV) system based on the concept of a perturb and observe (P&O) approach. It is an iterative algorithm that requires a starting point to trace the maximum power point tracking. This study proposes the P&O MPPT algorithm for a 3-ɸ grid-connected PV system. In this work, the PV system is modeled as a DC grid-connected PV system, and the MPPT algorithm is applied to that model. An MPPT application is used in this proposal to amplify the effectiveness of the PV array in face of any unsteady climatic circumstances. Hence, the highest energy could be secured out of the solar PV array and interfaced with the grid. The voltage source converter will empower defining of boundaries and greatest degrees of force from sunlight-based chargers in an efficient way. A few outcomes like the current, voltage and result power for each different mix have been noted.
