 Abstract

Real photographs frequently contain complex blur, such as the combination of space-variant and space-invariant blur, which is challenging to mathematically represent. In this work, we provide a cutting-edge blur kernel-free picture deblurring technique. We use two photographs, one fuzzy with low shutter speed and low ISO noise, and the other noisy with fast shutter speed and high ISO noise, both of which may be easily obtained in low-light conditions. By dividing the blurred picture into patches, we can use the corresponding patches in the noisy image to extend the Gaussian mixture model (GMM) and describe the underlying intensity distribution of each patch. Utilizing an analysis of the optical flow between the two pictures, we generate patch correspondences. The Expectation Maximization (EM) algorithm is utilized to estimate the parameters of GMM. To preserve sharp features, we add an additional bilateral term to the objective function in the M-step. We eventually add a detail layer to the deblurred image for refinement. Extensive experiments on both synthetic and real-world data demonstrate that our method outperforms state-of-the terms of robustness, visual quality, and quantitative metrics.

 Abstract

There is an increasing trend to use products manufactured from the Carbon Fiber Reinforced Plastics or Carbon Fiber Reinforced Polymer (CFRP) composites in the industry like aerospace, automotive, sports, medical, renewable energy etc. It is because of the lighter weight, higher strength, hence, higher strength-to-weight ratio of these materials, their higher corrosion resistance, higher fatigue resistance etc. Manufacturing of products from CFRP composites need precise machining, including cutting. Cutting of these materials is very difficult and inefficient with non-laser traditional techniques. Using continuous wave (cw) or pulsed fiber lasers solves many of these limitations of cutting CFRP composites. These processes have been optimized by many researchers for reducing the heat affected zones (HAZ) by optimizing the laser parameters like its power, pulse duration, feeding speed etc. Finally the environmental hazards of laser-based cutting of CFRP composites and the safety measures are also discussed in this paper.

 Abstract

The development of MEMS has been driven by the need for miniaturization and lowering the overall manufacturing cost. The field of MEMS is concerned with the development of integrated systems of sensors, actuators and associated electronics. Even though the electronics industry provides an economy of scale for the silicon industry, crystalline silicon is still a complex and relatively expensive material to produce. The development of polymer micromachining technologies that complement traditional silicon approaches has enabled the broadening of microelectromechanical systems (MEMS) applications. Polymeric Bio-MEMS (Biomedical Micro-Electro-Mechanical Systems) have great potential in their current and future applications which include genomics, proteomics, molecular diagnostics, point-of-care diagnostics, tissue engineering, single cell analysis and implantable micro-devices. The polymeric materials are very fragile and not rigid which restrict their manufacturing processes. To minimize many such problems, excimer lasers and femtosecond lasers have been used for the precise micromachining of Bio-MEMS, the details of which are discussed in this paper.

 Abstract

The banking sector has undergone a significant transformation with the adoption of Artificial Intelligence (AI). Prior to AI adoption, many banks faced challenges such as inefficient manual processes, inadequate risk management, loan processing , credit scoring, poor customer experience and major cyber crime issues. However, AI has emerged as a game-changer, enabling banks to streamline operations, improve customer service, enhance security, personalize offerings, fraud detection, ROI maximization and tailor solutions. This research explores the current state of AI in banking and financial services, as well as how AI can overcome cyber crime in banks with the help of cyber security wing. Stepping up AI adoption it will predict online frauds, loan defaults by using AI algorithms and to train the data to learn how to respond to different situations. The AI industry in India is expected to reach$7.8 billion by 2026, with a significant chunk of this investment coming from the banking sector. This study also gives an insight into the positive and negative impact of an Artificial Intelligence in Indian Banking Industries and also cyber crime issues related to banking sector. This paper gives the detail of the descriptive nature of customer awareness And perception toward the Artificial intelligence

 Abstract

Rohinton Mistry's Such a Long Journey (1991) is a seminal work in Indian English literature, narrating the plight of the middle-class Parsi protagonist Gustad Noble amidst the socio-political turbulence of 1970s Bombay. The novel is a rich interplay of private loss and public betrayal, examining how personal lives are deeply impacted by the larger forces of history and politics. This paper investigates how Mistry portrays the decay of urban life, the erosion of moral and political ideals, and the spiritual crisis faced by the individual. It also situates the novel within the broader framework of postcolonial literature, exploring its thematic complexity, historical consciousness, and literary craftsmanship. Through a close reading of the text and engagement with secondary scholarship, the paper offers a comprehensive understanding of Such a Long Journey as both a historical document and a humanist narrative.

 Abstract

The movement for the unification of Karnataka was a historic and transformative process aimed at integrating all Kannada-speaking regions into one administrative entity. The unification movement, spanning several decades, culminated in 1956 with the establishment of Karnataka state, reshaping the political, cultural, and social landscape of the region. This article presents a qualitative analysis of the significance of this movement, delving into its causes, the challenges encountered, the post-unification scenario, and suggestions for the region's future growth. By exploring the intricacies of the movement and its aftermath, this paper aims to provide a comprehensive understanding of the impact of the unification on Karnataka's identity, unity, and development.

 Abstract

After India attained independence in 1947, the country faced the herculean task of political integration, with over 560 princely states scattered across the subcontinent. These states were not legally bound to join either India or Pakistan, and their future was uncertain. Sardar Vallabhbhai Patel, India's first Deputy Prime Minister and Home Minister, played a pivotal role in bringing about the peaceful integration of these diverse states into the Indian Union. With remarkable diplomacy, foresight, and determination, Patel used a mix of persuasion, strategic force, and legal mechanisms to unify India. This paper explores his instrumental role, the challenges faced, the strategies adopted, and the lasting impact on India's unity and sovereignty. It also assesses literature on the subject and offers findings and suggestions for contemporary nation-building efforts.

 Abstract

The concept of viscosity is commonly used to characterize a material, but it is not adequate to describe the mechanical behavior of a substance, particularly non-Newtonian fluids. several other rheological properties which relate the relations between the stress and strain rate tensors under different flow conditions, such as oscillatory shear, or extensional flow can be described the mechanical behavior of non-Newtonian fluids like Blood. Viscoelasticity is a rheological phenomenon that describes the flow properties of complex fluids like blood. Viscoelastic materials have interesting properties. They exhibit both viscous behavior as well as elasticity. The viscosity and elasticity of blood are direct indicators of how these parameters affect the ability of the blood to flow under the shear conditions imposed by the pulsatility of the circulation. The present study aims at 1.)To measure velocity of blood for different flow rates in a capillary tube, which is achieved by allowing the blood to flow in a capillary tube of different radii and 2) To measure ultrasonic velocity and absorption in blood at different frequencies. The data is presented and findings and conclusions are drawn from this data.
