Towards birational aspects of moduli space of curves
No full textThesis (S.M.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2010.Cataloged from PDF version of thesis.Includes bibliographical references (p. 43-46).The moduli space of curves has proven itself a central object in algebraic geometry. The past decade has seen substantial progress in understanding its geometry. This has been spurred by a flurry of ideas from geometry (algebraic, symplectic, and differential), topology, combinatorics, and physics. One way of understanding its birational geometry is by describing its cones of ample and effective divisors and the dual notion of the Mori cone (the closed cone of curves). This thesis aims at giving a brief introduction to the moduli space of n-pointed stable curves of genus ... and some intuition into it and its structure. We do so by surveying what is currently known about the ample and the effective cones of ... , and the problem of determining the closed cone of curves ... The emphasis in this exposition lies on a partial resolution of the Fulton-Faber conjecture (the F-conjecture). Recently, some positive results were announced and the conjecture was shown to be true in a select few cases. Conjecturally, the ample cone has a very simple description as the dual cone spanned by the F-curves. Faber curves (or F-curves) are irreducible components of the locus in ... that parameterize curves with 3g - 4 + n nodes. There are only finitely many classes of F-curves. The conjecture has been verified for the moduli space of curves of small genus. The conjecture predicts that for large g, despite being of general type, ... behaves from the point of view of Mori theory just like a Fano variety. Specifically, this means that the Mori cone of curves is polyhedral, and generated by rational curves. It would be pleasantly surprising if the conjecture holds true for all cases. In the case of the effective cone of divisors the situation is more complicated. F-conjecture. A divisor on ... is ample (nef) if and only if it intersects positively (nonnegatively) all 1-dimensional strata or the F-curves . In other words, every extremal ray of the Mori cone of effective curves NE1(Mg,n) is generated by a one dimensional stratum. The main results presented here are: (i) the Mori cone ... is generated by F-curves when ...by Shashank S. Dwivedi.S.M

‘Offensive’ writing: Sex and prostitution in the works by Hansda Sowvendra Shekhar
No full textThis article considers some works by the Santhal author Hansda Sowvendra Shekhar in light of the fierce critiques they attracted. Against the accusation of pornographic and offensive writing, I maintain not only that the criticism Shekhar’s works received is unjustified (something that has also been claimed by others), but also that it is symptomatic of a mood with its roots in the West that has spread all over the world. I argue that behind this kind of criticism lies the imposition of identity politics on literary works on one side, and the contemporary concern with political correctness on the other. Further, I also show that despite the progressive agenda such a criticism wants to represent and defend, it ends up producing regressive implications. Shekhar’s case appears thus to be particularly enlightening in showing the limits of identity politics and political correctness in literary criticism
Action-Reflection-Adaptation-Public Learning: Excerpts from the Life of a Pracademic. Larry Susskind in conversation with Shekhar Chandra
No full textLarry Susskind is Ford Professor of Urban and Environmental Planning at the Massachusetts Institute of Technology (MIT). His research interests focus on the theory and practice of multiparty negotiation and public dispute resolution, the practice of public engagement in local decision-making, global en-vironmental treaty-making, and the resolution of science-intensive policy disputes, particularly those related to climate change adaptation. He is an experienced mediator, having helped to settle more than 50 resource management and development disputes in many parts of the world, mostly through the Consensus Building Institute, which he founded in 1991. Larry is the author or co-author of more than twenty books including, most recently, Environmental Problem-Solving (Anthem), Managing Climate Risks in Coastal Communities: Strategies for Engage-ment, Readiness, and Adaptation (Anthem), the second edition of Environmental Diplomacy (Oxford Press), and Good for You, Great for Me (Public Affairs Press).He is one of the co-founders of the in-ter-university Program on Negotiation at Harvard Law School, where he now directs the MIT-Harvard Public Negotiations Program, serves as Vice-Chair for Instruction, and co-directs the Negotiation Pedagogy Initiative. This booklet is based on the author’s frequent interactions with Larry over several years at MIT. During his doctoral studies, the author has had multiple opportunities to work with Larry that not only inspired the author’s research but also exposed him to some of Larry’s important scholarly contributions to the planning field. Conversations in the booklet are grouped under five broad public policy questions to which Larry has made important contributions.AESOP Young Academics Booklet Project Conversations in Planning, Booklet
Topological Relationships and Their Use
No full textTopological relations between spatial objects have been widely recognized, implemented, and used in GIS. They provide a notion of the general structure and the interactions of spatial objects. Topology avoids dealing with geometry by introducing topological primitives, namely, boundary, interior, and exterior.Accepted Author ManuscriptUrban Data Scienc
Stereo-PIV Measurement of Turbulence Shear Stress in a Stirred Flow Mixer
No full textThe turbulence dissipation rate and turbulence shear stress are estimated inside a cylindrical, stirred flow mixer by carrying out Stereo PIV measurements in twelve vertical and three horizontal planes. The flow domain is vertically oriented, filled with the water. A commercially-available, three-blade impeller, HR-100, is used as the agitator. The impeller is mounted near the tip of a thin, rigid shaft, which is aligned along the central axis of the flow domain. The impeller rotates with the constant angular speed of 150RPM, and the Reynolds number based on the impeller diameter and the blade's tip-velocity is equal to 59400. The turbulence statistics in the vertical measurement planes are reported before (Shekhar C, Nishino K, Yamane Y and Huang J, \u93Stereo-PIV measurement of turbulence characteristics in a flow mixer\u94 Journal of Visualization 15 (2012) pp.293~308), which revealed that the rotation induces a downward, as well as tangential, bulk flow motion, which convects the turbulence generated at the blade-water interface, causing the turbulence level below the impeller to be much higher than the level above it. The present study is the second part of the same project, and reports the turbulence statistics in the horizontal measurement planes. The results show that the turbulence level is high in the area swept by the rotating impeller blades and underneath. However, in the outside region, the turbulence damps down and becomes negligible. The vertical and horizontal measurement results are also combined to estimate the production, convection, viscous diffusion, and turbulence dissipation terms of the turbulence kinetic energy's budget equation, along with the turbulence shear stress, along the lines where the different vertical and horizontal planes intersect
