 Abstract

Object detection plays a crucial role in modern computer vision, enabling applications ranging from autonomous driving and surveillance to robotics and healthcare. Traditional methods relied on handcrafted features such as Haar, HOG, and SIFT combined with classical classifiers like SVM and Adaboost. However, the advent of deep learning revolutionized object detection through Convolutional Neural Networks (CNNs) and advanced models such as the R-CNN family, YOLO, SSD, and Transformers. This review compares traditional and deep learning-based methods, summarizing their advantages, limitations, and applications while highlighting current challenges and potential future research directions.

 Abstract

The diaspora, which spans numerous regions and occupations, serves as a dynamic link between India and the global population. This abstract examines the Indian diaspora's impact on foreign policy, including its diplomatic, cultural, and economic aspects. From an economic perspective, the diaspora is a vital asset, supporting India's economy through investments, remittances, and business ventures. It fosters understanding and respect for Indian customs abroad and serves as a cultural ambassador. The diaspora uses advocacy, lobbying, and networking in host countries to exert diplomatic influence and improve India's soft power. Divergent perspectives and different allegiances among the diaspora provide challenges for Indian foreign policy. This abstract's short appraisal of the complex relationship between the diaspora and foreign policy emphasizes the Indian diaspora's transformative impact on India's global engagement.

 Abstract

This research examines customer opinion and satisfaction about Samsung goods in the Tiruchirappalli district, a notable market region in Tamil Nadu, India. The study mainly examines customer perceptions of Samsung as a brand and the degree of satisfaction with its goods in areas like cellphones, home appliances, and consumer electronics. The primary aims include identifying the determinants of customer preferences, evaluating the effects of product quality, innovation, price, availability, and after-sales service on contentment, and comprehending the influence of brand image on purchasing choices. Data collection was executed using a standardised questionnaire sent to a representative sample of Samsung customers in the neighbourhood. The comments were examined to discern trends and insights on customer behaviour. The results indicate that product quality and brand trust are essential determinants of customer happiness. Consumers acknowledged Samsung's creativity and technical progress but expressed issues around cost and the accessibility of service centres. The research elucidates generational disparities in perception and satisfaction, revealing that younger customers prioritise features and cost, whilst older populations emphasise durability and after-sales assistance. The report finishes with suggestions for Samsung to improve customer happiness in the Tiruchirappalli area. Recommendations include the implementation of localised marketing tactics, enhancement of service centre availability and accessibility, provision of competitive pricing, and ongoing innovation to address changing customer demands. This study offers significant insights for Samsung and comparable firms seeking to enhance their market presence in regional markets by matching their products with customer expectations.

 Abstract

The concept of Sah?daya - the ideal reader or spectator, is a cornerstone of Sanskrit poetics, embodying the refined sensibility required to fully experience rasa - the aesthetic essence of a work. This paper delves into the role and significance of Sah?daya as envisioned in classical texts, particularly the N??ya??stra and later elaborations by theorists like ?nandavardhana and Abhinavagupta. Far from being a passive observer, the Sah?daya is portrayed as an active participant whose cultivated taste, emotional receptivity, and intuitive grasp of suggestion (dhvani) allow for a profound engagement with poetic art. By analysing the qualities that define a Sah?daya, this paper highlights the dynamic interplay between artistic creation and aesthetic reception, reaffirming the continued relevance of this concept in discussions of literary theory and the philosophy of art.

 Abstract

The hallmark of diabetic mellitus (DM), a long-term metabolic disease, is hyperglycemia brought on by deficiencies in either insulin release or secretion, or both. With a projected of 537 million people affected globally in 2021 and predictions that this figure will increase to 783 million people by 2045, it has become a significant global health concern. Despite their effectiveness, traditional antidiabetic treatments like diabetes drugs and oral hypoglycemic medications are frequently linked to side effects like hypoglycemia, stomach problems, increased weight, and costly therapy. Because of their multiple intended activities, reduced adverse effect profiles, and affordability, traditional medications and organic items have gained popularity as alternate or additional methods to managing diabetes mellitus in the last few years. Many herbal products, such as the bark of Momordica charantia, Gymnasium sylvestre, but also Trinidad foenum- graecum, and opium sacred, have shown anti- diabetes properties through a variety of mechanisms, such as increased glucose production, enhanced glucose response, suppression of molecules that break down carbohydrates, antioxidant effects, and the defense of pancreatic ?-cells. Experimental and preliminary testing has shown encouraging results about the risk and effectiveness of various natural remedies. But there are still issues like inconsistent bioavailable chemicals, a lack of standards, and a dearth of extensive research studies. To sum up, botanical treatments present a viable adjunctive approach to the treatment of diabetes mellitus. When combined with traditional therapies and subjected to thorough scientific analysis, they may offer safer, more potent, and multipurpose diabetic therapy alternatives.

 Abstract

Gender equality in higher education involves not only eliminating structural barriers and gender-based discrimination, but also promoting inclusive, diverse, and effective educational policies that guarantee equitable and diversity-respecting academic environments. This perspective constitutes a fundamental axis for achieving sustainable development and building a more just, democratic, relevant, and quality society. This article aims to critically analyze the treatment of gender equality mainstreaming in the context of the Bengo Polytechnic Institute in Angola. The research is framed within a qualitative methodology, supported by a documentary review and theoretical analysis of the main conceptualizations of gender and their application in higher education. The results identify structural challenges, institutional gaps, and opportunities for improvement, with the aim of contributing to a more effective, transformative, and sustained implementation of the gender approach in Angolan higher education institutions.

 Abstract

The synthesis and characterization of nano ferrites have emerged as critical research areas due to their vast potential in cutting-edge technologies. Their exceptional electrical and magnetic properties--strongly shaped by the synthesis technique--enable a broad spectrum of advanced applications. This review highlights and compares a variety of synthesis methods, including sol-gel, auto-combustion, self-combustion, co-precipitation, reverse micelle, micro-emulsion, glass crystallization, precursor-based, and hydrothermal techniques, each contributing uniquely to the structural and functional attributes of nano ferrites. We focus on mixed metal ferrites with the general formula MFe?O? (where M = Cu, Fe, Mg, Mn, Ni, etc.), known for their superior performance over single-component systems. These nano ferrites exhibit remarkable properties such as high coercivity, magnetic anisotropy, Curie temperature, mechanical hardness, enhanced electrical resistivity and reduced eddy current losses. Our comprehensive analysis reveals that cation distribution, particle size, and morphology influence their behaviour. Mixed nano ferrites are versatile materials for various high-impact applications, including electronics, catalysis, sensors, data storage, and biomedicine. This review aims to understand better their synthesis strategies, core properties, and transformative potential in real-world applications.
