Transient MHD Radiative Fluid Flow over an Inclined Porous Plate with Thermal and Mass Diffusion: An EFDM Numerical Approach
No full textIon-Slip Effects on Bingham Fluid Flowing Through an Oscillatory Porous Plate with Suction
No full textThis paper investigates the remarkable effects for introducing the Ion-slip characteristics in the magnetohydrodynamic phenomena on the drift of Bingham fluid when flowing through the inner territory of two porous parallel plates in correspondence with the suction case. The lower plate (L-plate) is as steady while the upper one (U-plate) is oscillatory, which oscillates in its own plane at time t>0. A magnetic field, which is uniform, is affixed perpendicular to the plates. The U-plate temperature oscillates while the L-plate temperature is constant. Numerical performance is presented by the MATLAB R2015a simulation tool with the explicit Finite difference Method (FDM) algorithm. To ensure the preciseness and convergence of the solutions, careful attention has been given on the criteria of stability and convergence of the FDM schemes. As an outcome, the converged solution is obtained for Pr ≥ 0.066, βi ≥ 2, Ha ≤ 20, h ≤ 8, S ≥ −10 and Re ≤ −0.017 with the arbitrary choice of βe = 0.10 and Ec = 0.01. The mesh sensibility test gives the competent mesh space at (m,n)=(60,60). The time sensibility test ensures that the solutions at dimensionless time, τ=2.0 will be steady-state. The exactitude of the current study is obtained by comparing with the published results. Finally, the physical influences of several governing parameters, including Ionslip on the fluid property like velocity, local shear stress, temperature and Nusselt number are discussed and decorated graphically
#nowplaying-rs
No full text<p>The nowplaying-rs dataset features context- and content features of listening events. It contains 11.6 million music listening events of 139K users and 346K tracks collected from Twitter. The dataset comes with a rich set of item content features and user context features, as well as timestamps of the listening events. Moreover, some of the user context features imply the cultural origin of the users, and some others - like hashtags - give clues to the emotional state of a user underlying a listening event.</p>
<p>The dataset contains three files:</p>
<ul>
<li>user_track_hashtag_timestamp.csv contains basic information about each listening event. For each listening event, we provide an id, the user_id, track_id, hashtag, created_at </li>
<li>context_content_features.csv: contains all context and content features. For each listening event, we provide the id of the event, user_id, track_id, artist_id, content features regarding the track mentioned in the event (instrumentalness, liveness, speechiness, danceability, valence, loudness, tempo, acousticness, energy, mode, key) and context features regarding the listening event (coordinates (as geoJSON), place (as geoJSON), geo (as geoJSON), tweet_language, created_at, user_lang, time_zone, entities contained in the tweet).</li>
<li>sentiment_values.csv contains sentiment information for hashtags. It contains the hashtag itself and the sentiment values gathered via four different sentiment dictionaries: AFINN, Opinion Lexicon, Sentistrength Lexicon and vader. For each of these dictionaries we list the minimum, maximum, sum and average of all sentiments of the tokens of the hashtag (if available, else we list empty values). However, as most hashtags only consist of a single token, these values are equal in most cases. Please note that the lexica are rather diverse and therefore, are able to resolve very different terms against a score. Hence, the resulting csv is rather sparse. The file contains the following comma-separated values: <hashtag, vader_min, vader_max, vader_sum,vader_avg, afinn_min, afinn_max, afinn_sum, afinn_avg, ol_min, ol_max, ol_sum, ol_avg, ss_min, ss_max, ss_sum, ss_avg >, where we abbreviate all scores gathered over the Opinion Lexicon with the prefix 'ol'. Similarly, 'ss' stands for SentiStrength. </li>
</ul>
<p>Please note that user_track_hashtag_timestamp.csv and context_content_features.csv partly provide the same features. We deliberately chose to do so to be able to provide useable files that do not have to be matched and joined with each other to perform e.g., simple recommendation tasks.</p>
<p>Please also find the training and test-splits for the dataset in this repo. Also, Asmita provides prototypical implementations of a context-aware recommender system based on the dataset at https://github.com/asmitapoddar/nowplaying-RS-Music-Reco-FM.</p>

A Low SWaP-C Radar Altimeter Transceiver Design for Small Satellites
No full textThis paper discusses the design details of a high resolution, low "Size, Weight, Power and Cost" (SWaP-C) radar altimeter (RA) system. Operating frequency of the radar is chosen within the Ka-band to achieve the desired size and weight requirements, that are highly demanded for the small satellite missions in a cost-efficient way. We propose a system design such that, an intended radar altimeter can be built by using the Commercial off the Shelf (COTS) components. The simulation results show that the proposed RA has high potentiality for realization.Accepted author manuscriptMicrowave Sensing, Signals & SystemsAtmospheric Remote SensingMathematical Geodesy and Positionin
Multistatic Radar Imaging for Traffic Monitoring
No full textThis work presents a novel radar system for vehicle imaging. The proposed system is based on estimation of target parameters like range and velocity and generation of the final radar image. For this purpose, a multistatic Frequency Modulated Continuous Wave (FMCW) Synthetic Aperture Radar (SAR) system is implemented. Both the simulation and on site measurements show that such a radar system has the potential to replace the current very expensive sensors.Accepted author manuscriptMicrowave Sensing, Signals & System
Psychedelics as Tools for Self-Development: An Integral Approach: Psychedelics as Tools for Self-Development: An Integral Approach
No full textThis project attempts to explore and answer the question “ As seen from an integralperspective, how can psychedelic substances best be used as tools for self-development? ”. Inorder to explore this, the project utilizes Spiral Dynamics and Integral Theory, in particularthe Quadrant Model, put forth by author Ken Wilber. The paper features 3 separateinterviews as its primary research data, supplemented by an excerpt from GrahamHancock’s book “ The Divine Spark” and an excerpt from Dr. Richard Louis Miller’s book“Psychedelic Medicine” . In the analysis, the research question is explored by the applicationof Spiral Dynamics in order to delineate the personal growth, experienced by the subjects,as result of using psychedelic substances. In extension of this, these changes are positionedin relation to The Quadrant Model. Followingly, the literary excerpts are also analyzed, andso provide an additional layer of depth to the analysis. Concludingly, the findings of theproject form a comprehensive framework based on The Quadrant Model. The function ofthis framework is to offer anyone, who seeks to utilize psychedelic as tools for personaldevelopment, valuable insights and considerations in order to ensure a successful outcome.This project attempts to explore and answer the question “ As seen from an integralperspective, how can psychedelic substances best be used as tools for self-development? ”.

Political Participation of Minors in India: A Critical Perspective from the Prism of the UNCRC
No full textThe participation of children in a political demonstration has proven to be an enduring issue in India owing to the public agitations against the Citizenship Amendment Act and the farm laws, with the latter being withdrawn recently. Under the hegemonic liberal paradigm, the underlying risk is that civil and political rights may be envisaged as the exclusive domain of adults. Children are merely viewed as apprentice citizens who do not have the capacity to exercise rational choice. The operative presumption is located in a binary wherein children are pliant beneficiaries, and the state is a benign caretaker in charge of determining their best interests. It thereby negates children’s autonomy and reduces them to disenfranchised spectators in an adult-centric social fabric. Moreover, the protectionist approach enables the state to evade its obligation of preserving democratic spaces wherein minors can protest safely and make their voices heard. State functionaries and judicial authorities in India have also been complicit in adopting an infantilising stance. In this paper, the author makes a case for recognising the agency of children such that they can exercise their ‘autonomy’ right to political participation. This paper incorporates diverse perspectives in existing child rights literature, including those emanating from the Global South, to argue in favour of an epistemic reorientation in child rights law discourse. Moreover, the author relies upon key interpretations of UNCRC provisions made by the Committee on the Rights of the Child and argues for facilitating a participative environment where children can exercise their civil and political rights. The ‘best interests’ test should not be wielded as a sword from an adult standpoint to curtail children’s rights in the political domain.Keywords: Children's Rights, Citizenship Act, Political Participation
Alternative Dispute Resolution for Sustainable Peace: A Pragmatic Proposition
No full textIn lieu of formal judicial process under the common law jurisprudence, tools and techniques of alternative dispute resolution (hereafter ADR) - as the same are so called ~ stand way ahead toward peace-building discourse in the contemporary society, as it was earlier. In forthcoming paragraphs. the author strives to articulate with arguments of his own - and corroborate (t)his position that (i) in Its given time and place - the twenty-first century South Asia - ADR, in technical sense of the term, seems a misnomer, because the same stands here in vogue as the mainstream judicious process toward peaceful settlement of disputes between and among individuals or group of individuals since time immemorial; (ii) also, with wide variety of tools and techniques of ADR, the author grapples with jurisprudence of the same to attain sustainable peace sans remnants of prejudice against one another. Besides, in perspective of hitherto ordeal of common law - procedural Law in particular - the author asserts imperative need for minute introspection toward befitting jurisprudence to suit the soil and its people in South Asia; thereby, get rid of the given piecemeal peace process the State grapples with in the course of its myopic dispute governance
