    A Novel Vision Transformer Approach for Driver Fatigue Detection from EEG Signal with Correlation-Based Channel Selection
    (Scopus, 2024-12-19) Khan, Robiul; Roy, Dipon; Ali, Md. Wajed; Refat, Kawsar Ahmed; Naziullah, Shekh
    Driver fatigue poses a critical threat to road safety, necessitating the development of robust detection methods to minimize traffic accidents and societal burdens. Deep neural networks have recently been effectively applied to Electroencephalography (EEG)-based driving fatigue detection. Nevertheless, most of the existing models, particularly those relying on extensive pooling, often struggle to capture long range dependencies within images. To address this issue, we propose a Correlation-based Channel Selection (CCS) with a Vision Transformer (ViT) approach for driver fatigue detection using an EEG. Our methodology integrates a pioneering Channel Selection (CS) block to extract discriminative channels via CCS. This mechanism systematically identifies the most informative EEG channels crucial for fatigue detection. Subsequently, we leverage Continuous Wavelet Transform (CWT) to convert the selected EEG channels into a time-frequency spectral image. Finally, the resulting time-frequency spectral images, encompassing both temporal and spectral information, are concatenated and fed into the Vision Transformer (ViT) model to classify them as either normal or fatigued. The proposed model is evaluated on a publicly available EEG dataset containing recordings from twelve subjects. The model achieved superior accuracy: 95.83% for the effective selected combined subject and 99.925% for the average accuracy of each subject, demonstrating its potential for robust driver fatigue detection.

    Discrimination Against Women: Legal Gaps and the Role of Reform in Promoting Gender Equality"
    (Daffodil International University, 2025-11-11) Roy, Dipon
    Discrimination against women is defined as the people who are treated differently simply due to their gender identity or gender expression. Discrimination can present in a variety of ways, such as unbalanced treatment in the workplace, less access to education, less access to health care, and social exclusion. Discrimination reinforces negative stereotypes, impedes social equity, and irrationally impedes growth. Discrimination against women is a complex and multifaceted issue with historical roots. Discrimination is often tied to societal norms that come from historical belief systems around role-based expectations, perceptions of gender-based roles, and perceptions of power imbalances, which are often unconsciously reinforced, and the degree of impact on individuals relates to opportunities and experiences, and overall impact on well-being and health. Addressing discrimination takes an entire society approach, a multi-faceted approach that must address the conceptualization of social norms, with considerations for equitable opportunity and social norms through incentives, laws, etc., ensuring that there are legal protections for all people, irrespective of their gender identity or gender expression.
