Sub-sampling Approach for Unconstrained Arabic Scene Text Analysis by Implicit Segmentation based Deep Learning Classifier
Get PDFThe text extraction from the natural scene image is still a cumbersome task to perform. This paper presents a novel contribution and suggests the solution for cursive scene text analysis notably recognition of Arabic scene text appeared in the unconstrained environment. The hierarchical sub-sampling technique is adapted to investigate the potential through sub-sampling the window size of the given scene text sample. The deep learning architecture is presented by considering the complexity of the Arabic script. The conducted experiments present 96.81% accuracy at the character level. The comparison of the Arabic scene text with handwritten and printed data is outlined as well
ESL University Students2019; Attitudes Towards Using WhatsApp in Academic Writing
No full textThis study examined the relationship between behavioural intention and the Technology Acceptance Model (TAM) variables: Perceived usefulness, ease of use and attitudes towards WhatsApp tool in teaching and learning academic writing skills in Botswana. This study accurately hypothesized a positive and significant relationship between behavioural intention to use WhatsApp in academic writing and dimensions of usefulness, and extent of use of WhatsApp. However, there was no significant relationship between ease of use and behavioural intention (0.436); and perceived web based privacy (0.878). 120 questionnaires were distributed with a response rate of 85%. 70 questionnaires were administered at the University of Botswana and 50 at Botho University also in Botswana. The questionnaire consisted of a 5-Point Likert Scale. The data were subjected to validity and reliability in order to explicate the psychometric competence of the scale items in the Botswana context. Correlation and regression analysis established the association and relationship of the hypothesized sub-constructs in this study. Simple random probability sampling technique was adopted in this empirical study. Scale items were adapted from Davis2019;s (1989) TAM model. The findings thus provide a strategic platform for understanding learners in Synchronous and Asynchronous discussion in Digital Learning mode of the 21st Century

In the scenario of transmitting encrypted text message over AWGN and Rayleigh fading channels, it is noticeable that implementation of Repeat and Accumulate channel coding and Group Detection (GD) approach aided Efficient Zero- Forcing (ZF) signal detection techniques is very much robust and effective in retrieving transmitted text messages for all users
On Application of Artificial Neural Networks to Control Quality of Protection Environment
Get PDFThe principles of constructing artificial neural networks for a quality control system for the operation of ship equipment related to environmental protection are considered. The concentration of harmful substances in exhaust gases and bilge waters depends on many factors related to both the condition of the equipment and external conditions. Analytically describing this dependence is extremely difficult, therefore, it is proposed to use artificial neural networks to monitor the state of equipment. The paper describes how to create a neural network such as a self-organizing feature map and methods for its training
