BCI establishes a connection between the brain and a computer system, primarily focusing on assisting, enhancing, or restoring human cognitive and sensory - motor functions. BCI technology enables the acquisition of Electroencephalography (EEG) signals from the human brain. This research concentrates on analyzing the articulatory aspects, including Wernicke's and Broca's areas, for Silent Speech Recognition. Silent Speech Interfaces (SSI) offers an alternative to conventional speech interfaces that rely on acoustic signals. Silent Speech refers to the process of communicating speech in the absence of audible and intelligible acoustic signals. The primary objective of this study is to propose a classifier model for phoneme classification. The input signal undergoes preprocessing, and feature extraction is carried out using traditional methods such as Mel Frequency Cepstrum Coefficients (MFCC), Mel Frequency Spectral Coefficients (MFSC), and Linear Predictive Coding (LPC). The selection of the best features is based on classification accuracy for a subject and is implemented using the Integrated Stacking Classifier. The Integrated Stacking Classifier outperforms other traditional classifiers, achieving an average accuracy of 75% for both thinking and speaking states on the KaraOne dataset and approximately 86.2% and 84.09% for thinking and speaking states on the Fourteen Channel EEG for Imagined Speech (FEIS) dataset.","PeriodicalId":17010,"journal":{"name":"Journal of Scientific & Industrial Research","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135565601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This creates a fascinating phenomenon of user community acceptance and rating of these apps. Some apps are well-received by users due to factors such as performance, compatibility, and cost. This study has examined eleven factors that affect the performance of mobile banking apps like Google Pay, Phone Pay, and Paytm. Factors are identified by conducting a literature survey, analysing user reviews, and seeking expert opinions. It is worth noting that users tend to reject or dislike apps that pose challenges to them due to issues in the apps. Furthermore, the authors have utilized an Interpretive Structure Modeling (ISM) approach to develop a hierarchical structure for improvement of individual factors, along with MICMAC (Matrice d'Impacts Croisés Multiplication Appliquée á un Classment) analysis, to categorize the identified issues into four groups. Numerous studies have addressed issues related to mobile apps, but the classification or grouping of these issues has often been inadequate.

In the recent years, this wetland has witnessed significant changes owing to anthropogenic and natural factors. In this study, the land use and land cover changes are analyzed around the Ropar Wetland using remote sensing techniques by utilizing Landsat images and GIS software. The results showed a significant increase in agricultural land from 19% in 2000 to 37% in 2010, followed by a decrease to 28% in 2020. Barren, urban, and fallow land also showed a continuous increase from 20% in 2000 to 44% in 2020. The forest cover decreased from 47% in 2000 to 17% in 2020 and water bodies decreased slightly from 14% in 2000 to 10% in both 2010 and 2020. The pictorial representation of LULC (Land Use Land Change) changes over the years, including the area of the Ropar Wetland, provided insight into the shifting patterns of land use and cover. Results from NDWI (Normalized Difference Water Index) show a small decrease in water body area in the wetland over the years, with some fluctuations in the total area. MNDWI (Modified Normalized Difference Water Index) shows the sparse water area around the wetland. Natural processes including erosion and accretion have affected the wetland region around the river, causing a net loss of 55 hectares of land, over the past two decades. The findings of this study suggest that there is a need to implement effective management practices that recognize the complex interrelationships between land use, hydrology, and ecological processes to protect the Ropar Wetland's ecological and hydrological functions. Ongoing monitoring and assessing land use and cover changes are crucial for conserving wetland ecosystems.","PeriodicalId":17010,"journal":{"name":"Journal of Scientific & Industrial Research","volume":"48 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135566711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A level of student’s performance may be influenced by several factors like job of parents, sexual category and average scores obtained in prior years. Student’s performance prediction is a challenging chore, which can help educational staffs and students of educational institutions to follow the progress of students in their academic activities. Student performance enhancement and progress in educational quality are the most vital part of educational organizations. Presently, it is essential for an educational organization to predict the performance of students. Existing methods utilized only previous student performances for prediction without including other significant behaviors of students. For addressing such problems, a proficient model is proposed for prediction of student performance utilizing proposed Adaptive Aquila Optimization-allied Deep Convolution Neural Network (DCNN). In this process, data transformation is initiated using the Yeo-Johnson transformation method. Subsequently, feature selection is performed using Fisher Score to identify the most relevant features. Following feature selection, data augmentation techniques are applied to enhance the dataset. Finally, student performance is predicted through the utilization of a DCNN, with a focus on fine-tuning the network parameters for optimal performance. This fine-tuning is achieved through the use of the Adaptive Aquila Optimizer (AAO), ensuring the network is poised to deliver the best possible results in predicting student outcomes. Proposed AAO-based DCNN has achieved minimal error values of Mean Square Error, Root Mean Square Error, Mean Absolute Error, Mean Absolute Percentage Error, Mean Absolute Relative Error, Mean Squared Relative Error, and Root Mean Squared Relative Error, respectively.","PeriodicalId":17010,"journal":{"name":"Journal of Scientific & Industrial Research","volume":"49 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135566706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The literature survey shows various pulse compression techniques that are widely used to achieve superior range resolution and range detection performance. Several studies have been conducted on chaotic communication involving chaotic maps in recent years, producing promising results. These maps are used to generate different phase-coded sequences. The properties of the chaotic map sequences are almost random. The performance of these sequences has been studied with various optimization techniques in literature by employing a matched filter and a mismatched filter and is measured in terms of peak sidelobe ratio. But the performance has not improved significantly. This paper focused on improving performance using a new hybrid technique to design mismatched filters. This improvement is achieved by designing the coefficients of the mismatched filters using a combination of metaheuristic methods and an evolutionary algorithm for specializing in intensification and diversification. A significant improvement in the peak sidelobe ratio and range resolution is obtained when the mismatched filter is combined with adaptive filters at the output.","PeriodicalId":17010,"journal":{"name":"Journal of Scientific & Industrial Research","volume":"48 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135566709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of present study was to evaluate the ultrasonic sensors (viz. HC-SR04 and JSN-SR04T) for depth of flow and corresponding discharge rate measurement in irrigation channel of canal command. The effect of ambient temperature on ultrasonic sensors was also investigated for irrigation channel hydraulic response measurement. It was observed that the performance of calibrated and temperature compensated sensors was better than the uncalibrated ones. Moreover, the performance of JSN-SR04T was better with mean absolute deviation (MAD: 0.21 ± 0.01cm), root mean square error (RMSE: 0.82 ± 0.01) and mean absolute percentage error (MAPE: 0.46 ± 0.09) compared to HC-SR04 sensor with MAD (0.36 ± 0.07), RMSE (0.43 ± 0.08) and MAPE (1.54 ± 0.82), respectively. Hence, JSN-SR04T ultrasonic sensor was used in the developed sensing system for the measurement of flow depth. It was observed that the system measured flow rate when compared with the observed flow resulted in prediction error estimate MAD (0.13 ± 0.05 lps), RMSE (0.16 ± 0.05) and MAPE (2.09 ± 1.16) and coefficient of determination (R2: 0.99) for flow rate ranging from 2 to 20 lps. Overall, the study resulted in the development of a novel and economically viable open channel digital flow sensing system to measure discharge rate passing through the flume.
