Implicit spoken language diarization

Spoken language diarization (LD) and related tasks are mostly explored using the phonotactic approach. Phonotactic approaches mostly use explicit way of language modeling, hence requiring intermediate phoneme modeling and transcribed data. Alternatively, the ability of deep learning approaches to model temporal dynamics may help for the implicit modeling of language information through deep embedding vectors. Hence this work initially explores the available speaker diarization frameworks that capture speaker information implicitly to perform LD tasks. The performance of the LD system on synthetic code-switch data using the end-to-end x-vector approach is 6.78% and 7.06%, and for practical data is 22.50% and 60.38%, in terms of diarization error rate and Jaccard error rate (JER), respectively. The performance degradation is due to the data imbalance and resolved to some extent by using pre-trained wave2vec embeddings that provide a relative improvement of 30.74% in terms of JER

‘Is this a time of beautiful chaos?’: reflecting on international feminist legal methods

This article considers how Margaret Jane Radin’s theory of the feminist double bind can bring conceptual clarity to the difficulties feminisms face in engaging with political and legal institutions of global governance. I draw on her theory to reinitiate a conversation on ideal and nonideal theory, in order to answer the call of key proponents in international legal feminism to reevaluate methodologies in critiquing mainstream institutions. By providing an account of how to navigate the double bind, this article brings conceptual clarity to the tension between resistance and compliance that has been argued to lie at the heart of the feminist project in international law. I demonstrate how this theoretical framework can foster greater pluralist perspectives in feminist engagement of ideal theories to temper the deradicalising and conservative risk of navigating feasibility constrained nonideal strategies

Mahatma Gandhi and the Prisoner’s Dilemma: Strategic Civil Disobedience and Great Britain’s Great Loss of Empire in India

This paper examines the relationship between statutory monopoly and collective action as a multi-person assurance game culminating in an end to British Empire in India. In a simple theoretical model, it is demonstrated whether or not a collective good enjoys (or is perceived to enjoy) pure jointness of production and why the evolutionary stable strategy of non-violence was supposed to work on the principle that the coordinated reaction of a ethnically differentiated religious crowd to a conflict between two parties (of colonizer and colonized) over confiscatory salt taxation would significantly affect its course. Following Mancur Olson (1965) and Dennis Chong (1991), a model of strategic civil disobedience is created which is used to demonstrate how collective action can be used to produce an all-or-nothing public good to achieve economic and political independence

Effect of multilayer selective radiative anti-reflective coating on crystalline silicon photovoltaics for operating temperature reduction

Low heat transfer coefficient of ethylene-vinyl acetate hinders heat evacuation, and this causes a rise in temperature of the laminated solar module under AM1.5 spectrum. A new selective radiative antireflective coating (SR-ARC) has been proposed for the temperature reduction of the solar module and also effort has been made to improve the absorption in the 300–1100 nm wavelength range. We have compared the single, dual, triple and quad-layer of different transparent ARC materials with a different combination. In each category, we have optimised the SiO2, Al2O3, Si3N4 and TiO2 thin films layer stack as ARC coating and then compared the stacks for their SR-ARC properties.
