BANKING SECTOR REFORMS AND EQUITY - A SUB-REGIONAL ANALYSIS IN ANDHRA PRADESH
The changes in government policies are continuous to correct the ill effects of its earlier policies. In this study an attempt is made to examine the equity aspect due to reforms in the banking sector at sub-regional level in the state of Andhra Pradesh covering the period 1985 to 2004. The analysis indicates that the share of rural areas in number of branches, number of accounts, deposits and credit declined during pre and post liberalisation periods. Despite declining shares in most of the parameters especially those of credit and deposits, there is positive growth in both the periods. However, the growth of these parameters is more in urban areas. The distribution of credit among the sectors indicates that the share of agricultural sector in accounts and credit declined during pre and post liberalisation periods. The share of agricultural credit declined in all the regions during pre and post liberalisation periods. This is true with respect to credit and number of credit accounts. In the case of other sectors, the share in accounts and credit increased in both the periods. Though, the share in the agriculture sector declined in all the regions, per account credit increased in all the regions during both the periods. It may be concluded that liberalisation has increased inequalities. But the rate of increase in inequalities is arrested to a certain extent in the recent past. But if one looks at the growth of credit given to different sectors and growth of credit in rural and urban areas, one may not come to this kind of conclusion.Banking Sector Reforms, Equity, Andhra Pradesh
Transformational derivation of programs using the Focus system
A program derivation support system called Focus is being constructed. It will formally derive programs using the paradigm of program transformation. The following issues are discussed: (1) the integration of validation and program derivation activities in the Focus system; (2) its tree-based user interface; (3) the control of search spaces in program derivation; and (4) the structure and organization of program derivation records. The inference procedures of the system are based on the integration of functional and logic programming principles. This brings about a synthesis of paradigms that were heretofore considered far apart, such as logical and executable specifications and constructive and transformational approaches to program derivation. A great emphasis has been placed, in the design of Focus, on achieving small search spaces during program derivation. The program manipulation operations such as expansion, simplification and rewriting were designed with this objective. The role of operations that are expensive in search spaces, such as folding, has been reduced. Program derivations are documented in Focus in a way that the high level descriptions of derivations are expressed only using program level information. All the meta-level information, together with dependencies between derivations of program components, is automatically recorded by the system at a lower level of description for its own use in replay
A finite element solver for 3-D compressible viscous flows
Computation of the flow field inside a space shuttle main engine (SSME) requires the application of state of the art computational fluid dynamic (CFD) technology. Several computer codes are under development to solve 3-D flow through the hot gas manifold. Some algorithms were designed to solve the unsteady compressible Navier-Stokes equations, either by implicit or explicit factorization methods, using several hundred or thousands of time steps to reach a steady state solution. A new iterative algorithm is being developed for the solution of the implicit finite element equations without assembling global matrices. It is an efficient iteration scheme based on a modified nonlinear Gauss-Seidel iteration with symmetric sweeps. The algorithm is analyzed for a model equation and is shown to be unconditionally stable. Results from a series of test problems are presented. The finite element code was tested for couette flow, which is flow under a pressure gradient between two parallel plates in relative motion. Another problem that was solved is viscous laminar flow over a flat plate. The general 3-D finite element code was used to compute the flow in an axisymmetric turnaround duct at low Mach numbers
Total Minimal Dominating Signed Graph
Cartwright and Harary considered graphs in which vertices represent persons and the edges represent symmetric dyadic relations amongst persons each of which designated as being positive or negative according to whether the nature of the relationship is positive (friendly, like, etc.) or negative (hostile, dislike, etc.). Such a network S is called a signed graph. Signed graphs are much studied in literature because of their extensive use in modeling a variety socio-psychological process and also because of their interesting connections with many classical mathematical systems
Anticipatory adjustments to being picked up in infancy
Anticipation of the actions of others is often used as a measure of action understanding in infancy. In contrast to studies of action understanding which set infants up as observers of actions directed elsewhere, in the present study we explored anticipatory postural adjustments made by infants to one of the most common adult actions directed to them - picking them up. We observed infant behavioural changes and recorded their postural shifts on a pressure mat in three phases: (i) a prior Chat phase, (ii) from the onset of Approach of the mother's arms, and (iii) from the onset of Contact. In Study 1, eighteen 3-month-old infants showed systematic global postural changes during Approach and Contact, but not during Chat. There was an increase in specific adjustments of the arms (widening or raising) and legs (stiffening and extending or tucking up) during Approach and a decrease in thrashing/general movements during Contact. Shifts in postural stability were evident immediately after onset of Approach and more slowly after Contact, with no regular shifts during Chat. In Study 2 we followed ten infants at 2, 3 and 4 months of age. Anticipatory behavioural adjustments during Approach were present at all ages, but with greater differentiation from a prior Chat phase only at 3 and 4 months. Global postural shifts were also more phase differentiated in older infants. Moreover, there was significantly greater gaze to the mother's hands during Approach at 4 months. Early anticipatory adjustments to being picked up suggest that infants' awareness of actions directed to the self may occur earlier than of those directed elsewhere, and thus enable infants' active participation in joint actions from early in life
Gap solitons with null-scattering
We study excitation of gap solitons under the conditions of coherent perfect
absorption (CPA). Our system consists of a symmetric periodic structure with
alternating Kerr nonlinear and linear layers, illuminated from both the ends.
We show near-total transfer of incident light energy into the gap solitons
resulting in null-scattering. We also report on the nonlinear super-scattering
(SS) states. Both the CPA and the SS states are shown to be characterized by
typical field distributions. Both the exact and the approximate results (based
on nonlinear characteristic matrix method) are presented, which show good
agreement
