ABSTRACT - Data sharing is an important functionality in cloud storage. In this paper, we show how to securely, efficiently, and flexibly share data with others in cloud storage. We describe new public-key cryptosystems that produce constant-size ciphertexts such that efficient delegation of decryption rights for any set of ciphertexts are possible. The novelty is that one can aggregate any set of secret keys and make them as compact as a single key, but encompassing the power of all the keys being aggregated. In other words, the secret key holder can release a constant-size aggregate key for flexible choices of ciphertext set in cloud storage, but the other encrypted files outside the set remain confidential. This compact aggregate key can be conveniently sent to others or be stored in a smart card with very limited secure storage. We provide formal security analysis of our schemes in the standard model. We also describe other application of our schemes. In particular, our schemes give the first public-key patient-controlled encryption for flexible hierarchy, which was yet to be known.

 Abstract

Exhaust manifolds play a crucial role in enhancing the performance of Internal Combustion (IC) engines, and their design is paramount for optimal functionality. This article focuses on conducting a Computational Fluid Dynamics (CFD) analysis to assess the impact of velocity, temperature, and back pressure on the overall (volumetric) efficiency of exhaust manifolds. Specifically, two different designs of exhaust manifolds are compared in this study. Furthermore, the investigation is extended to evaluate the influence of various fuels, including LPG, alcohol, and gasoline, on the overall efficiency. The obtained results are compared to determine the most effective design for the exhaust manifolds. The CFD analysis is carried out using ANSYS software and FUSION 360 software. Gasoline fuel exhibited lower pressure and velocity values, while type A manifold demonstrated higher pressure values, indicating superior performance and efficiency compared to type B manifold.

 Abstract

The Hahn-Banach Theorem is a fundamental result in functional analysis with profound implications in various branches of mathematics. Traditionally, its proofs have been presented using algebraic and analytic techniques. However, this research paper takes a novel approach by providing a geometric insight into the proof of the Hahn-Banach Theorem. By leveraging geometric concepts and visualizations, we aim to enhance the understanding and intuition behind this important result. The paper begins by introducing the Hahn-Banach Theorem and its significance in functional analysis. We then delve into the geometric interpretation of the theorem, highlighting the key geometric ideas that underlie its proof. We explore the geometric notions of separation and convexity, which form the basis for the Hahn-Banach Theorem's geometric formulation. We present a step-by-step geometric proof of the Hahn-Banach Theorem, elucidating the connections between geometric concepts and the mathematical arguments. We employ diagrams, illustrations, and visual aids to aid in the comprehension of the proof, providing readers with an intuitive understanding of the geometric reasoning involved. We discuss the advantages of the geometric approach in terms of its clarity, visualization, and potential for geometric generalizations. We compare and contrast our geometric proof with traditional algebraic and analytic proofs, highlighting the unique insights and advantages offered by the geometric perspective. We discuss applications of the Hahn-Banach Theorem in other areas of mathematics, showcasing the significance of understanding its geometric foundations. We conclude by emphasizing the value of geometric insights in facilitating a deeper understanding of the theorem and its broader implications. This research paper presents a geometric approach to proving the Hahn-Banach Theorem, providing readers with new insights into this fundamental result. By employing geometric intuition and visualization, we aim to enhance comprehension, foster geometric thinking, and promote further exploration of the Hahn-Banach Theorem in both functional analysis and related fields.

 Abstract

In this paper we first solve a double convolution integral equation involving the product of the general class of polynomials.On account of the general nature of our main result, solutions of a large number of other double convolution integral equations involving the product of several useful polynomials can also be obtained as its special cases. The one variable analogue of the main result which is also quite general in nature and of interest in itself has also been given. A special caseof this latter result yields a known formula obtained by Srivastava and Buschman (3).

 Abstract

This presentation highlights the life and works of some eminent women scientists in Chemistry and Biochemistry - now no more with us. The path to eminence was not easy for the pioneers. The pioneering woman scientist in Chemistry was Professor (Mrs.) Asima Chatterjee, the first woman General President of the Indian Science Congress Association. Asima Chatterjee primarily studied the Chemistry and medicinal properties of plants native to India. Her research contributed to the development of drugs that treated epilepsy and malaria amongst others. Kamala Sohonie, of the same generation, was the first Indian woman to earn a PhD degree in Science from Cambridge University. She was one of the earliest scientists working on Biochemistry in India. She became the Director of the Institute of Science, Bombay. Of two succeeding generations Darshan Ranganathan and Charusita Chakravarty made significant contributions to Organic and Bio-organic Chemistry, and Theoretical Chemistry, respectively.

 Abstract

Management education has a vital role to play in today's dynamic business environment since the management graduates play a key role in the economic development of the country. With the dynamic changes taking place in the economic scenario; it makes it even more difficult for organisations to survive in the competitive environment. Management institutions have mushroomed in India, but quality delivered by them still remains elusive. It is a well-admitted fact the Indian management education is struggling very hard to survive with the rapid changing global scenario. It is at the crossroads where it needs direction and vision immediately. Hence, it is my responsibility to highlight the challenges in the Indian management education to make it relevant with the changing times and technologies.
