Yash Chopra
No full textAs a charismatic director in the Indian film industry, Chopra’s name is synonymous with the glamour of the romantic film and a certain style within Indian culture. Spanning four decades, his directed features include some of the classic films of Indian film history, such as Deewaar and Kabhi Kabhie. His directorial career began in 1959 with Dhool Ka Phool and he has been a major producer since 1973, consolidating his success in the 1990s with a series of huge box office hits including Dilwale Dulhaniya Le Jayenge. He has also worked in other Hindi movie genres, directing action movies such as Mashaal and a thriller, Darr. This book discusses in depth his work with the Hindi megastar Amitabh Bachanan in films such as Deewaar, Trishul, Kala Patthar and Silsila and how, in his transformation of the look of mainstream cinema in Dil To Pagal Hai and other films, Yash Chopra has proved to be a tireless innovator within a mainstream tradition. The author integrates this analysis with information about the man and his work, based on interviews with Yash Chopra, his family, his colleagues, his stars, his contemporaries and major critics that include views from Amitabh Bachchan, Shahrukh Khan, Shashi Kapoor and Sri Devi. A study of a top contemporary Indian film director, Rachel Dwyer’s book also examines the influence on Chopra of predecessors such as Raj Kapoor and how his own legacy can be seen in such films as Kuch Kuch Hota Hai and younger directors such as Karan Johar and Aditya Chopra

The competition for partners in matching markets
No full textWe study the competition for partners in two-sided matching markets with heterogeneous agent preferences, with a focus on how the equilibrium outcomes depend on the connectivity in the market. We model random partially connected markets, with each agent having an average degree d in a random (undirected) graph and a uniformly random preference ranking over their neighbors in the graph. We formally characterize stable matchings in large random markets with small imbalance and find a threshold in the connectivity d at [Formula: see text] (where n is the number of agents on one side of the market), which separates a “weak competition” regime, where agents on both sides of the market do equally well, from a “strong competition” regime, where agents on the short (long) side of the market enjoy a significant advantage (disadvantage). Numerical simulations confirm and sharpen our theoretical predictions, and demonstrate robustness to our assumptions. We leverage our characterizations in two ways: First, we derive prescriptive insights into how to design the connectivity of the market to trade off optimally between the average agent welfare achieved and the number of agents who remain unmatched in the market. For most market primitives, we find that the optimal connectivity should lie in the weak competition regime or at the threshold between the regimes. Second, our analysis uncovers a new conceptual principle governing whether the short-side enjoys a significant advantage in a given matching market, which can moreover be applied as a diagnostic tool given only basic summary statistics for the market. Counterfactual analyses using data on centralized high school admissions in a major U.S. city suggests that both our design insights and our diagnostic principle have practical value.

Problems, limitations and implementational failures in public interest environmental litigation through an analysis of the Kanpur tanneries Ganga pollution …
No full textThe field of environmental law has seen an influx of litigation, especially public interest litigation, in cases where the government policy or the institutional machinery of Pollution Control Boards has failed to bring redressal. Dereliction becomes a matter of grave public concern - big enough to allow an individual to seek the Court's directions to avoid any further harm to the environment, and ultimately protect human rights. One such case has been that of MC Mehta v. Union of India,1 that is, the Kanpur TanneriesGanga Pollution case, wherein a citizen in his own capacity looked to prevent tanneries situated in Kanpur from polluting and discharging their trade affluents in Ganga. 2 The matter was raised after steps were not taken by industries and the concerned lawful authorities to control this act of public nuisanc
Accretion rates and radiative efficiencies of Sagittarius A* and nearby supermassive black holes estimated using empirical relations: Implications for accretion models
No full textThe Bondi accretion rate of black holes in our and nearby galaxies Messier
87, NGC 3115, NGC 1600, and Cygnus A have been determined or constrained using
Chandra or other observations. It, however, remains unknown how much mass from
the Bondi radius reaches each black hole and how much is accreted. We determine
the accretion rate and radiative efficiency for each black hole using two
well-tested empirical relations: one relates a black hole's accretion rate to
its mass and redshift, and the other relates the radiative efficiency to the
Eddington ratio and redshift. We get an accretion rate of ~0.00002 solar mass
per year and radiative efficiency of ~0.9 for Sagittarius A* and an accretion
rate of ~0.09 solar masses per year and radiative efficiency of ~0.68 for NGC
1600; and values in between these extremes for the rest. The derived mass
inflow rate onto each black hole (not the accretion rate) essentially matches
the reported Bondi accretion rate. Thus, the results do not support the ADIOS
and CDAF models, but whether the dissipated energy not reflected in a black
hole's observed luminosity is advected as in the ADAF model remains uncertain.
Furthermore, contrary to current model expectations, the derived radiative
efficiencies are orders of magnitude higher and radiative efficiency increases
as the accretion rate decreases and a BH ages. A physical basis is found
relating the empirical formulation of accretion rate to Bondi accretion.Comment: 11 pages, 1 figure, i tabl

MPC-based motion cueing algorithm for a 6 DOF driving simulator with actuator constraints
No full textDriving simulators are widely used for understanding Human-Machine Interaction, driver behavior and driver training. The effectiveness of such simulators in this process depends largely on their ability to generate realistic motion cues. Though the conventional filter-based motion cueing strategies have provided reasonable results, these methods result in poor workspace management. To address this issue, linear MPC-based strategies have been applied in the past. However, since the kinematics of the motion platform itself is non-linear and the required motion varies with the driving conditions, this approach tends to produce sub-optimal results. In this thesis, a nonlinear MPC-based algorithm is presented which incorporates the non-linear kinematics of the Stewart platform within the MPC algorithm to increase the effectiveness and utilize maximum workspace. Further, adaptive weights-based tuning is used to smoothen the movement of the platform near its physical limits. Full-track simulations were carried out and performance indicators were defined to objectively compare the response of the proposed algorithm with classical washout filter and linear MPC-based algorithms. The results indicate a better reference tracking with lower root mean square error and higher shape correlation for the proposed algorithm. Lastly, the effect of the adaptive weights based tuning was also observed in the form of smoother actuator movements and better workspace utilization
