Why only few are so successful ?
In many professons employees are rewarded according to their relative
performance. Corresponding economy can be modeled by taking independent
agents who gain from the market with a rate which depends on their current
gain. We argue that this simple realistic rate generates a scale free
distribution even though intrinsic ability of agents are marginally different
from each other. As an evidence we provide distribution of scores for two
different systems (a) the global stock game where players invest in real stock
market and (b) the international cricket.Comment: 8 pages, 3 eps figures, elsart.cls (included), accepted in Physica
Authentication Based on Texture Analysis And SVM Classification
This paper presents for identification and here used a fusion mechanism that amalgamates both, a Canny Edge detection and a Circular Hough Transform to detect the iris boundaries in the eye’s digital image. We then applied the Gabor Wavelet filter instead of using 1D Log-Gabor filter in order to exact the deterministic patterns in a person’s iris in the form of a feature vector. By comparing the quantized vectors using the Hamming Distance operator, we determine finally and for classification used Support vector Machine
Critical Behavior of Sandpile Models with Sticky Grains
We revisit the question whether the critical behavior of sandpile models with
sticky grains is in the directed percolation universality class. Our earlier
theoretical arguments in favor, supported by evidence from numerical
simulations [ Phys. Rev. Lett., {\bf 89} (2002) 104303], have been disputed by
Bonachela et al. [Phys. Rev. E {\bf 74} (2004) 050102] for sandpiles with no
preferred direction. We discuss possible reasons for the discrepancy. Our new
results of longer simulations of the one-dimensional undirected model fully
support our earlier conclusions.Comment: 8 pages, 3 eps figures, accepted in Physica A, elsart.cls attache
An Empirical Study of Branding Strategy at Dealer point for Selling of Car-a qualitative & systematic Review of Literature
India is one of the world’s fastest growing automobile markets and is poised to become the third largest passenger’s car market by 2020 (Philip, L. 2016, Economic Times). The recorded sales growth of 4 wheelers like passenger car & utility vehicle has also risen up to 7.87 % and 6.25% respectively during April-March 2016 (SIAM, 2015-16). But what makes a car maker like Japan’s Maruti Suzuki and Korea’s Hyundai enjoys more than 67% of market share while others like US car makers Ford India and General Motors combined market share is just 4-5%(Philip,L.2016,The Economic Times). Sales in the North & East region have evidenced only 5%of changes in the FY16 which is comparatively lower than the west & south region (Khan,A.N,2016, The Economic Times). The Japanese car makers(Honda, Hyundai, Isuzu Motors, Nissan &Toyota) achieved an average of 48.01% of growth till July 2016 having a better stand from the Indian car makers (Hindustan Motors, M&M,M&S, Tata & Force motors) i.e. 6.74% (Autocar Pro News Desk, July 2016). In this study the researcher explored the factors affecting the satisfaction of prospective car buyers and existing car users at dealer point and facilitate dealer to create a brilliant “moment of truth” (Pioneered by JanCarlzon) when a customer encounter with company.(Madge, Davidson & Beaujean, 2006
Evaluation of the carcass and commercial characteristics of carps
The role of carcass evaluation techniques in aquaculture research programs, especially in genetics, breeding, production management, feeding and nutrition, cannot be overemphasized. Knowledge of production efficiencies and growth potentials in relation to desired carcass attributes has provided an impetus to improvements in genetic selection techniques and management of aquatic food animals. Accurate, standard and uniform methods of carcass evaluation are critically important. A standard format developed for collection of data on carps is presented in this paper
A novel realization of the Calogero-Moser scattering states as coherent states
A novel realization is provided for the scattering states of the -particle
Calogero-Moser Hamiltonian. They are explicitly shown to be the coherent states
of the singular oscillators of the Calogero-Sutherland model. Our algebraic
treatment is straightforwardly extendable to a large number of few and
many-body interacting systems in one and higher dimensions.Comment: 9 pages, REVTe
Finite-time fluctuations in the degree statistics of growing networks
This paper presents a comprehensive analysis of the degree statistics in
models for growing networks where new nodes enter one at a time and attach to
one earlier node according to a stochastic rule. The models with uniform
attachment, linear attachment (the Barab\'asi-Albert model), and generalized
preferential attachment with initial attractiveness are successively
considered. The main emphasis is on finite-size (i.e., finite-time) effects,
which are shown to exhibit different behaviors in three regimes of the
size-degree plane: stationary, finite-size scaling, large deviations.Comment: 33 pages, 7 figures, 1 tabl
