Human Virtues and Vices in Shakespeare's Julius Caesar
Bala Swamy
Indian Streams Research Journal , 2012,
Abstract: The exposition of human nature is at its zenith in Shakespeare's tragic and historical playJulius Caesar which has 'its magnificent scenes and memorable characters.'1 The play isa study of love, friendship and human relationships. It answers the questions like whydoes an honest man err? Why do friends misunderstand each other and go to the extent ofmurdering each other? Why even good qualities like bravery and truthfulness getpunished? The present article is a study of the concepts like honesty, bravery andjealousy which emerge from the play. These qualities are portrayed in the personalitiesof the major characters who become symbols of these qualities. Julius Caesar is adifferent kind of tragedy because here, all the major characters get killed whether goodor bad.

Instrumentation in ultrasound cardiography
Swamy VMK
Journal of Postgraduate Medicine , 1979,
Abstract: Cardiac ultrasound/Echocardiography is a. simple, safe and non-invasive method for detecting heart diseases. When combined with ECG, X-ray and isotopic studies, ultrasound provides signifi-cant diagnostic information not previously available. M-Mode technique gives a unidimensional representation of movements of various structures of the heart whereas stop-action imaging or real time imaging gives a clear two-dimensional view of the various sections of the heart, thus permitting a comparison of anatomical juxta-positioning and continuity.

Improved Approximation Algorithms for Matroid and Knapsack Median Problems and Applications
Chaitanya Swamy
Computer Science , 2013,
Abstract: We consider the {\em matroid median} problem \cite{KrishnaswamyKNSS11}, wherein we are given a set of facilities with opening costs and a matroid on the facility-set, and clients with demands and connection costs, and we seek to open an independent set of facilities and assign clients to open facilities so as to minimize the sum of the facility-opening and client-connection costs. We give a simple 8-approximation algorithm for this problem based on LP-rounding, which improves upon the 16-approximation in \cite{KrishnaswamyKNSS11}. Our techniques illustrate that much of the work involved in the rounding algorithm of in \cite{KrishnaswamyKNSS11} can be avoided by first converting the LP solution to a half-integral solution, which can then be rounded to an integer solution using a simple uncapacitated-facility-location (UFL) style clustering step. We illustrate the power of these ideas by deriving: (a) a 24-approximation algorithm for matroid median with penalties, which is a vast improvement over the 360-approximation obtained in \cite{KrishnaswamyKNSS11}; and (b) an 8-approximation for the {\em two-matroid median} problem, a generalization of matroid median that we introduce involving two matroids. We show that a variety of seemingly disparate facility-location problems considered in the literature---data placement problem, mobile facility location, $k$-median forest, metric uniform minimum-latency UFL---in fact reduce to the matroid median or two-matroid median problems, and thus obtain improved approximation guarantees for all these problems. Our techniques also yield an improvement for the knapsack median problem.
Algorithms for Probabilistically-Constrained Models of Risk-Averse Stochastic Optimization with Black-Box Distributions
Chaitanya Swamy
Computer Science , 2008,
Abstract: We consider various stochastic models that incorporate the notion of risk-averseness into the standard 2-stage recourse model, and develop novel techniques for solving the algorithmic problems arising in these models. A key notable feature of our work that distinguishes it from work in some other related models, such as the (standard) budget model and the (demand-) robust model, is that we obtain results in the black-box setting, that is, where one is given only sampling access to the underlying distribution. Our first model, which we call the risk-averse budget model, incorporates the notion of risk-averseness via a probabilistic constraint that restricts the probability (according to the underlying distribution) with which the second-stage cost may exceed a given budget B to at most a given input threshold \rho. We also a consider a closely-related model that we call the risk-averse robust model, where we seek to minimize the first-stage cost and the (1-\rho)-quantile of the second-stage cost. We obtain approximation algorithms for a variety of combinatorial optimization problems including the set cover, vertex cover, multicut on trees, min cut, and facility location problems, in the risk-averse budget and robust models with black-box distributions. We obtain near-optimal solutions that preserve the budget approximately and incur a small blow-up of the probability threshold (both of which are unavoidable). To the best of our knowledge, these are the first approximation results for problems involving probabilistic constraints and black-box distributions. A major component of our results is a fully polynomial approximation scheme for solving the LP-relaxation of the risk-averse problem.
Electrochemical Synthesis of Titanium Nano Particles at Carbon Paste Electrodes and Its Applications as an Electrochemical Sensor for the Determination of Acetaminophen in Paracetamol Tablets  [PDF]
K. J. Gururaj, B. E. Kumara Swamy
Soft Nanoscience Letters (SNL) , 2013, DOI: 10.4236/snl.2013.34A006
Abstract: Titania nano particles were synthesized at carbon paste electrode by cyclic voltammetry and then it was employed for the determination of acetaminophen in phosphate buffer at pH 7.4. Carbon paste electrode with titania nano particle displayed excellent electrochemically catalytic activities by shifting the oxidation potential of acetaminophen towards the negative side. The mass transfer process at electrochemical interface was diffusion controlled. Electrochemical techniques such as, electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization methods were used to measure the resistance of the electrodes. The resistance of the titanium electrode decreased in two orders when compared to the bare carbon paste electrode; the decrease in the resistance of the electrode and increase in the surface area of the electrode are responsible for the negative shifting of the oxidation potential of acetaminophen. The present method was applied to the determination of actetaminophen in paracetamol tablet, urine and blood sample by using standard addition method and the obtained results were satisfactory with a good recovery of 98%.
Delivering Low Income Housing-Role of Access to Land and Credit in Gujarat, India  [PDF]
Jay Mittal, H. M. Shivanand Swamy
Current Urban Studies (CUS) , 2014, DOI: 10.4236/cus.2014.23023
Abstract: Housing, particularly for the poor and marginalised, is a complex urban problem that occupies centre-stage in present-day development issues. Access to housing is influenced by two major fac-tors—land, and finance. Absence of either (or both) of these results in mushrooming of high density, environmentally insanitary living areas commonly referred to as slums. The poor and vulnerable sections increasingly struggle to secure adequate quality of shelter, because of their inability to access land at affordable rates and finance to be built. As the inflow of the poor from rural to urban is, by now, accepted as inevitable, providing housing and economic opportunities for these would have to form part and parcel of any sustainable urban development strategy. In the state of Gujarat, formal housing supply is unable to meet even a fraction of the housing demands in urban areas. Thus a mix of private and informal sector housing has emerged in the past few decades. During the 1990s, the involvement of NGOs in facilitating access of the poor to housing finance also became increasingly significant. This paper presents a critical review of housing delivery systems in urban Gujarat with an emphasis on the poor. A schematic design for delivery of land and access to housing finance for poor households has also been presented.
