Gas purification using membrane gas absorption processes

Owing to the increasing energy demand and the abundance of low quality natural gas reservoirs containing high percentages of CO2, considerable attention is given to the bulk removal of CO2 and upgrading of low quality natural gas. The main goal in doing so is to increase the heating value of natural gas and to reduce the transportation cost

TOWARDS DEMAND DRIVEN PUBLISHING: APPROCHES TO THE PRIORITISATION OF DIGITISATION OF NATURAL HISTORY COLLECTIONS DATA

Natural history collections represent a vast repository of biodiversity data of international significance. There is an imperative to capture the data through digitisation projects in order to expose the data to new and established users of biodiversity data. On the basis of review of current state of digitization of natural history collections, a demand driven approach is advocated through the use of metadata to promote and increase access to natural history collection data

Deterministic Factorization of Sparse Polynomials with Bounded Individual Degree

In this paper we study the problem of deterministic factorization of sparse polynomials. We show that if $f \in \mathbb{F}[x_{1},x_{2},\ldots ,x_{n}]$ is a polynomial with $s$ monomials, with individual degrees of its variables bounded by $d$, then $f$ can be deterministically factored in time $s^{\mathrm{poly}(d) \log n}$. Prior to our work, the only efficient factoring algorithms known for this class of polynomials were randomized, and other than for the cases of $d=1$ and $d=2$, only exponential time deterministic factoring algorithms were known. A crucial ingredient in our proof is a quasi-polynomial sparsity bound for factors of sparse polynomials of bounded individual degree. In particular we show if $f$ is an $s$-sparse polynomial in $n$ variables, with individual degrees of its variables bounded by $d$, then the sparsity of each factor of $f$ is bounded by $s^{O({d^2\log{n}})}$. This is the first nontrivial bound on factor sparsity for $d>2$. Our sparsity bound uses techniques from convex geometry, such as the theory of Newton polytopes and an approximate version of the classical Carath\'eodory's Theorem. Our work addresses and partially answers a question of von zur Gathen and Kaltofen (JCSS 1985) who asked whether a quasi-polynomial bound holds for the sparsity of factors of sparse polynomials

Survey of Socio-Economic status of rural Women: Analysis of aoSwayam siddhaa

Women make up 52 of our country s population Women have an important role in building up the contemporary Society but the socio-economic status of women is very poor rated Government is trying to change this scenario by implementation of several schemes like Swashakti Swadhar Swayam siddha Swayamsiddha is the scheme of socio-economic upliftment of rural women It has been started by department of Women Child Development in year 2001 Swayamsiddha worked in the rural routs by the help of Self Help Group SHG model of microfinance Swayamsiddha has been covered 650 Blocks of all states of the country The first phase of scheme is completed recentl

Africa's adjustment to transnational capital : the political economy of the African Union and the New Partnership for Africa's Development.

This dissertation situates Africa’s macro-restructuring through the AU-NEPAD in the context of a disciplined post-colonial Africa. It challenges the claims of the AU-NEPAD as being reflective of the aspirations of Africa’s people and the appropriate African solution to Africa’s structural challenges. This study argues that the ostensible counterhegemonic discourse of AU-NEPAD vis-à-vis global capitalism merely expresses a new politics of reformism that ensures Africa integrates its national circuits of accumulation into global capitalism on the terms of transnational capital. Africa’s adjustment to transnational capital through the AU-NEPAD is not the same as national debt based conditionality adjustment. Instead, AU-NEPAD macro-restructuring is treated as a multidimensional class project to ensure a new African order is constituted in which Africa’s states and societies are further subordinated to the non-hegemonic rule of transnational capital. AU-NEPAD macro-restructuring is central to facilitating Africa’s continental passive revolution and creating the conditions for a new scramble for Africa’s natural resources, markets and states. This study explains the role of AU-NEPAD macro-restructuring as a class project of the transnational fraction of Africa’s ruling classes in three ways. First, it highlights how the shifting relations of force of a disciplined Africa spawned a conjuncture in which nationally based transnational class formation and structural change created the conditions for a continental project of Afro-neoliberal macro-restructuring. This study historicises the underpinnings of this project. It shows how a class consensus emerged around new concepts of control for the macro-restructuring of Africa. Such new concepts of ‘security and stability’, ‘liberal democracy’, ‘globalisation’ and ‘partnership’ cemented the basis for a common Afro-neoliberal consensus within the transnational fraction of Africa’s ruling classes. This consensus expressed itself concretely through the AUNEPAD and indigenised transnational neoliberalism as Afro-neoliberalism at the continental level. iv Second, this study goes inside the AU-NEPAD project to understand how Afroneoliberalism works at the level of macro-restructuring as distinct from national structural adjustment to transnational capital. It shows how macro-restructuring is a form of adjustment but grounded in situated class practices at a continental level. Such class practices are materially grounded and express the structural and direct power of the transnational fraction of Africa’s ruling class to advance AU-NEPAD macrorestructuring. Concepts, principles, discourses, policy frameworks and various tactics are expressions of these class practices. In this study the AU-NEPAD is based on five key strategic thrusts which inform class practices inside AU-NEPAD macro-restructuring: (i) the discourse of the African Renaissance and Afro-neoliberal capitalism through which pan-Africanism is appropriated; (ii) the imposition and construction of partnership on the continent; (iii) using peace and stability interventions not just to end conflict but to implant Afro-neoliberal societies and assimilate illiberal Africa; (iv) excluding and coopting mass forces and (v) fostering ‘partnership’ with the US-led transnational historical bloc. Finally, this study explains AU-NEPAD macro-restructuring as a class project by bringing into view how Afro-neoliberalism as an instrument of class rule is further defined at the intersection with and through responses from key multi-lateral and private transnational institutions within the US-led transnational historical bloc. This study shows how the UN, the IMF and World Bank, the G8 and the World Economic Forum embrace AU-NEPAD macro-restructuring and globalise a consensus about what Africa means and what its development challenges and solutions are. In this process of hegemonic engagement Africa is integrated into global capitalism through a new balance between consent and coercion and the politico-ideological integration of the Afroneoliberal historic bloc into the US-led transnational historical bloc on the terms of transnational capital

Early Warning Signals for Cryptocurrency Market States

Being archetypal complex systems, financial markets exhibit rich set of dynamics in their interactions. In this paper, we focus on the recently evolved cryptocurrency market as an example of a complex system and analyse the evolution of cross correlation structure of cryptocurrencies in the 5 year period from 2017 to 2022. We observe characteristic correlation structures in the observation time window duration and use these specific structures to cluster the cryptocurrency market in 4 market states

Design and Development of a Computer Vision Algorithm and Tool for Currency Recognition in Indian Vernacular Languages for Visually Challenged People

God created this universe and all living and non-living entities. Human is one of the best among His creations and in Human beings, eyes are the best gift of God to see His creations. As of now, humans are considered as the only developed creatures among God's creations and have developed themselves from Stone Age to the Computing Era. As the human civilizations grew up, the transactions have moved from barter system to currency. Every country has its own currency in terms of coins and paper notes. Each of the currency of Individual County has its unique features, colors, denominations and international value. We, all, having been given two beautiful eyes could recognize the currency easily but the same is not easy for blind people. The denomination can easily be recognized for a currency but it becomes difficult to identify a counterfeit currency from the real one. Especially for the blind people, it is a herculean task like finding a needle from haystack. The motive behind this work is to develop and test a robust computer vision algorithm(s) to identify the Indian currency, mainly paper-based currency, in Indian Regional languages
