Ek duniyā alag sī Narrative strategies and Adivasi representation in the short stories of Vinod Kumar
No full textThis paper investigates the narrative strategies of representation used by the Indian author Vinod Kumar in his literary writing about the life and spaces of the Adivasi. The focal point of this study consists in the fact that the author is a non-Adivasi, thus placing him and his writing in the center of a very much debated issue of Hindi literature i.e. the polarity between the writing through sympathy (Hindi sahānubhūti) and the writing through personal experience (anubhūti). This study-case looks at how the author, being a dikū, an outsider describes the ‘other’ (i.e. the Adivasi). The results show that the author’s representation of the Adivasi, based on a solid empirical knowledge of his ‘other’, contains some elements of romanticism revealing both his outsideness and a strong empathy for the ‘other’.Masteruppsats i indologi 2019</p

Parameterized algorithms for conflict-free colorings of graphs
No full textIn this paper, we study the conflict-free coloring of graphs induced by neighborhoods. A coloring of a graph is conflict-free if every vertex has a uniquely colored vertex in its neighborhood. The conflict-free coloring problem is to color the vertices of a graph using the minimum number of colors such that the coloring is conflict-free. We consider both closed neighborhoods, where the neighborhood of a vertex includes itself, and open neighborhoods, where a vertex does not included in its neighborhood. We study the parameterized complexity of conflict-free closed neighborhood coloring and conflict-free open neighborhood coloring problems. We show that both problems are fixed-parameter tractable (FPT) when parameterized by the cluster vertex deletion number of the input graph. This generalizes the result of Gargano et al.(2015) that conflict-free coloring is fixed-parameter tractable parameterized by the vertex cover number. Also, we show that both problems admit an additive constant approximation algorithm when parameterized by the distance to threshold graphs.
We also study the complexity of the problem on special graph classes. We show that both problems can be solved in polynomial time on cographs. For split graphs, we give a polynomial time algorithm for closed neighborhood conflict-free coloring problem, whereas we show that open neighborhood conflict-free coloring is NP-complete. We show that interval graphs can be conflict-free colored using at most four colors
The parameterized complexity of happy colorings
No full textConsider a graph G=(V,E) and a coloring c of vertices with colors from [?]. A vertex v is said to be happy with respect to c if c(v)=c(u) for all neighbors u of v. Further, an edge (u,v) is happy if c(u)=c(v). Given a partial coloring c of V, the Maximum Happy Vertex (Edge) problem asks for a total coloring of V extending c to all vertices of V that maximises the number of happy vertices (edges). Both problems are known to be NP-hard in general even when ?=3, and is polynomially solvable when ?=2. In [IWOCA 2016] it was shown that both problems are polynomially solvable on trees, and for arbitrary k, it was shown that MHE is \NPH{} on planar graphs and is \FPT{} parameterized by the number of precolored vertices and branchwidth.
We continue the study of this problem from a parameterized prespective. Our focus is on both structural and standard parameterizations. To begin with, we establish that the problems are \FPT{} when parameterized by the treewidth and the number of colors used in the precoloring, which is a potential improvement over the total number of precolored vertices. Further, we show that both the vertex and edge variants of the problem is \FPT{} when parameterized by vertex cover and distance-to-clique parameters. We also show that the problem of maximizing the number of happy edges is \FPT{} when parameterized by the standard parameter, the number of happy edges. We show that the maximum happy vertex (edge) problem is \NPH{} on split graphs and bipartite graphs and polynomially solvable on cographs

Assessment of Bubble Pump Model for Fluid Directional Motion from Asymmetric Heated Ratchets in Nucleate Boiling Regime
No full textPassive two-phase fluid cooling systems are of major interest for cooling electronics in terrestrial and micro gravity environments due to their compactness and minimization of moving parts. In this thesis, the use of asymmetry for bubble ebullition and growth on a heated surface to passively generate lateral motion of fluid within an open-ended channel is discussed. The asymmetry is achieved by locating reentrant slot cavities on one face of a mm-scale 30/60-degree ratchet. Two such ratcheted walls with cavities in every third ratchet form the vertical walls of an open-ended channel. The ratcheted walls are heated using a serpentine thick-film metallic heater. The open-ended channel is located within a quiescent pool of a dielectric fluid. Visualization studies show that bubbles and slugs tend to move in a preferential direction within the open channel. This direction corresponds to the 30-degree slope face of the ratchet, in which the reentrant cavity is located. Prior studies have alluded to two potential mechanisms for this preferential lateral motion- (1) bubble pump model developed by Kapsenberg et al. [14], which attributes the lateral motion to the momentum imparted by the growing bubble to the surrounding liquid, and (2) asymmetry in the curvature of the slug that spans several ratchet lengths, resulting in a net surface tension force along the 30-degree slope of the ratchet. In order to assess the importance of the bubble pump model, bubble ebullition and growth from the nucleation sites for different heat fluxes and subcooling temperatures are captured using high speed videos and are analyzed using custom image processing of high-speed videos. The major purpose of the image processing is to detect the bubbles in the frames and obtain height and diameter of the bubbles attached to the ratchet in each frame. Active contouring and segmentation techniques are used to detect bubbles in the frames. The velocity imparted by the growing bubble on the ratchet to the surrounding liquid is calculated using this data with the semi empirical model of Kapsenberg et al. This predicted velocity is compared against velocities of detached small (Stokes) bubbles in the field of view obtained using particle (bubble) tracking velocimetry. This comparative analysis has revealed that the semi empirical formula predicts the horizontal velocity imparted by the growing bubble on the ratchet with a deviation of ±15% of the horizontal velocity obtained from the particle tracking velocimetry except for high subcooling mid heat flux condition. Overall, it was observed that around 20-30 mm/s of lateral velocity is imparted in the surrounding fluid by the bubble growing on ratchet. These results validate the bubble pumping model and the semi empirical formula developed by Kapsenberg in the nucleate boiling regime.
Issues in adjustment lending
No full textReaping the full benefit of adjustment packages depends on a government's commitment to reform as well as a variety of complementary factors, many of which have not been duly considered because of the lack of time, resources, and skills. It is becoming increasingly clear that if these packages are to be more effective and credible, the menu of policy options might be expanded in three areas. One is translating adjustment policies into improved economic performance -- the objective of domestic strategy. The second is reconciling policy reforms with changing external strategy. The third is improving the process of adjustment itself. The report concludes that attention needs to be placed on the commitment to price reforms and nonprice areas. Support might increase for the outward orientation of countries -- if discussions are extended to consider external factors and if nondistortionary ways of promoting domestic production are explored. There must also be greater government commitment to building support for the reforms as well as flexiblity in the external financing community.Environmental Economics&Policies,Economic Theory&Research,Country Strategy&Performance,Achieving Shared Growth,ICT Policy and Strategies

Facilitated Tabletop Games in a Mediated Environment
No full textTabletop games that require the aid of a human facilitator are typically designed for a physical environment. However, during the COVID-19 pandemic, lockdown measures prevented people from gathering. Therefore, tabletop games were sometimes played and facilitated in a mediated environment using online communication tools instead. But this setting possibly deteriorates the players’ game experience. To understand the effect of playing facilitated tabletop games in a mediated environment we measured the player experience of the game Cue Kitchen in a mixed-method study comparing physical and mediated game sessions. Forty-four players played eleven game sessions, three in a physical environment and eight in a mediated environment. Of all seven dimensions of game experience measured, only one differed significantly between the two experimental conditions: players in a mediated environment became significantly more tired than players in a physical environment. The qualitative results explained why: players in a physical setting can wander off, while players in an online setting have to stay focused on their screen and, therefore, grow more tired. The research results suggest that facilitated tabletop games may be played in a mediated environment instead of a physical environment, without significant loss of player experience.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Policy AnalysisOrganisation & Governanc
“Risk Management Can Actually Be Fun”: Using the Serious Cards for Biosafety Game to Stimulate Proper Discussions About Biosafety
No full textAs part of a Dutch Science Foundation project called T-TRIPP, the authors developed the serious game Cards for Biosafety. The aim of Cards for Biosafety is to let young biotechnology researchers learn more about biosafety. Analyses of workshops with researchers from the biotechnology domain as well as results of interviews with several biosafety officers clearly indicated the need for such a serious game with a focus on educational learning. Cards for Biosafety is a physical (also playable online on Tabletopia) round-based card game and playable with up to eight players. The game itself consists of scenario, risk and measure cards, and the task of the players is to choose risk and measure cards that fit the scenario explained by the facilitator at the beginning of each round. To test the efficiency of Cards for Biosafety as a learning tool, the authors conducted two online-workshops with twelve participants. The results of these sessions have not only shown that Cards for Biosafety is a well-designed game, but also a successful game to achieve the intended learning goal. In addition, the authors recognized that ‘fun’ is an important element in the game which leads to ‘learning’ in a very effective way. Future research should focus on the role of such positive states in serious games and their influence on learning outcomes.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Policy AnalysisGame La
