Solution of wave-like equation based on Haar wavelet
Naresh Berwal,Dinesh Panchal,C. L. Parihar
Le Matematiche , 2012,
Abstract: Wavelet transform and wavelet analysis are powerful mathematical tools for many problems. Wavelet also can be applied in numerical analysis. In this paper, we apply Haar wavelet method to solve wave-like equation with initial and boundary conditions known. The fundamental idea of Haar wavelet method is to convert the differential equations into a group of algebraic equations, which involves a finite number or variables. The results and graph show that the proposed way is quite reasonable when compared to exact solution.
Bayesian and hierarchical Bayesian analysis of response - time data with concomitant variables  [PDF]
Dinesh Kumar
Journal of Biomedical Science and Engineering (JBiSE) , 2010, DOI: 10.4236/jbise.2010.37095
Abstract: This paper considers the Bayes and hierarchical Bayes approaches for analyzing clinical data on response times with available values for one or more concomitant variables. Response times are assumed to follow simple exponential distributions, with a different parameter for each patient. The analyses are carried out in case of progressive censoring assuming squared error loss function and gamma distribution as priors and hyperpriors. The possibilities of using the methodology in more general situations like dose- response modeling have also been explored. Bayesian estimators derived in this paper are applied to lung cancer data set with concomitant variables.
The Implications of Mandatory Corporate Social Responsibility—A Literature Review Perspective  [PDF]
Dinesh Ramdhony
Theoretical Economics Letters (TEL) , 2018, DOI: 10.4236/tel.2018.83031
Abstract: The purpose of this paper is to discuss the implications of mandatory corporate social responsibility (CSR) contributions: the CSR levy. Using public interest theory as the theoretical lens, this paper adopts a pro-regulation approach and justifies the introduction of the CSR levy in Mauritius, based on the economic and business environment prevailing at the time. Secondary literature sources are used to investigate. Two further questions related to mandatory CSR are investigated: Does the CSR levy result in a competitive disadvantage? Does the CSR levy reduce profits? We conclude that the CSR levy does not disadvantage firms due to the uniform amount and its universal application. Furthermore, it can attract Foreign Direct Investment (FDI) and Socially Responsible Investment (SRI). However, the CSR levy does negatively impact on profits but has the potential to pay higher returns in the future if viewed as an investment. This research needs to be complemented by studies that empirically investigate the impacts of the CSR levy on companies and sectors in Mauritius.
Some Common Fixed Point Theorems Satisfying Meir-Keeler Type Contractive Conditions  [PDF]

Open Journal of Discrete Mathematics (OJDM) , 2018, DOI: 10.4236/ojdm.2018.82004
Abstract: In this article, we establish some common fixed point results for two pairs of compatible mappings satisfying Meir-Keeler type contractive conditions in metric space and dislocated metric space which extend and improve some similar fixed point results in the literature.
Privacy Negotiation in Socio-Technical Systems  [PDF]
Murthy Rallapalli, Dinesh Verma
Technology and Investment (TI) , 2012, DOI: 10.4236/ti.2012.31003
Abstract: A socio-technical system (STS) is an approach to complex organizational work design that recognizes the interaction between people and technology in workplaces. The term also refers to the interaction between society’s complex infra-structures and human behavior. In this sense, society itself, and most of its substructures, are complex socio-technical systems. This paper addresses a class of socio-technical systems, represented by web services in a number of domains and attempts to understand the possibility of empowering the web users and consumers to have a say in the develop-ment of privacy agreements. This paper examines the likelihood of the web users and consumers leveraging such a capability, should it exist. This should improve the way privacy agreements are handled that benefits both the service providers and the web users.
A Unified Model of Neoarchean-Proterozoic Convergence and Rifting of Indian Cratons: Geophysical Constraints  [PDF]
Dinesh Chandra Mishra
International Journal of Geosciences (IJG) , 2011, DOI: 10.4236/ijg.2011.24063
Abstract: Neoarchean and Proterozoic sutures and collision zones are identified in the Indian Peninsular Shield based on high seismic velocity; gravity highs and high conductivity in the upper crust due to thrusting while sub- ducted side are demarcated based on geophysical signatures of crustal thickening and back arc type basins. Some of them appear to form triple junctions. The Bouguer anomaly map of the south Indian shield when transformed to apparent density map through harmonic inversion, provided high density linear zones coin- ciding with the shear zone and the transition zone-the Moyar Bhavani Shear Zone (MBSZ) between the Eastern Dharwar Craton (EDC) and the Western Dharwar Craton (WDC) and the Dharwar cratons and the Southern Granulite Terrain (SGT), respectively. It is supported by high seismic velocity and high conductiv- ity suggesting them to be caused by high grade granulite rocks related to Neoarchean-Paleoproterozoic su- tures and collision zones. These investigations also suggest thick crust (~40 - 50 km) under the WDC and the SGT forming crustal root of 50 - 52 km in the south western part and thin crust of 31 - 32 km under the EDC indicating direction of convergence and subduction as E-W and N-S between the EDC and the WDC and Dharwar cratons and the SGT, respectively. It gave rise to contemporary lower crustal granulite rocks in the northern part of the SGT and Cauvery shear zone (CSZ) as collision related central core complex of various deep seated intrusive rocks of Paleo-Mesoproterozoic period. The second case belonging to Meso-proterozoic period is related to the collision of the Bundelkhand craton and the Bhandara-Bastar craton (BBC) and the Dharwar craton (DC) in Central India along the Satpura Mobile Belt (SMB) and the BBC and the DC along the Godavari Proterozoic Belt due to N-S and NE-SW convergences, respectively. This process has given rise to lower crustal granulite rocks of high density, high velocity and high conductivity along the SMB and the GPB. An upper mantle conductor delineated south of the western part of the SMB under Dec- can Volcanic Province and a regional gravity gradient almost sub parallel to it indicate an interface with flu- ids separating rocks of different densities that appears to demarcate the trace of the Proterozoic subduction and suture related to the SMB collision zone during Mesoproterozoic period. High reflectivity of the lower crust along seismic profiles across the SMB indicate an extensional phase prior to this convergence. The SMB is connected to the Aravalli Delhi Mobile Belt (ADMB) in the western
New Electronically-Controllable Lossless Synthetic Floating Inductance Circuit Using Single VDCC  [PDF]
Dinesh Prasad, Javed Ahmad
Circuits and Systems (CS) , 2014, DOI: 10.4236/cs.2014.51003
Abstract:

A new electronically-controllable lossless floating inductance (FI) circuit (without any matching condition) has been presented, which employs only one Voltage Differencing Current Conveyor (VDCC), one grounded capacitor and one grounded resistor. The main aim of the paper is to present a new floating inductance simulator using single active device with minimum passive components. The proposed floating inductance simulator can be electronically controllable by changing the bias current. The workability of the new presented FI circuit has been verified using SPICE simulation with TSMC CMOS 0.18 μm process parameters.

A study of axi-symmetric waves through an isotropic thermoelastic diffusive medium
Kumar, Rajneesh;Panchal, Meenakshi;
Computational & Applied Mathematics , 2011, DOI: 10.1590/S1807-03022011000200001
Abstract: the paper deals with the propagation of axial symmetric cylindrical surface waves in a cylindrical bore through a homogeneous isotropic thermoelastic diffusive medium of infinite extent. the three theories of thermoelasticity namely, coupled thermoelasticity (ct), lord and shulman (l-s) and green and lindsay (g-l) are used to study the problem. the frequency equations, connecting the phase velocity with wave number, radius of bore and other material parameters, for empty and liquid filled bore are derived. the numerical results obtained have been illustrated graphically to understand the behaviour of phase velocity and attenuation coefficient versus wave number of a wave. a particular case of interest has also been deduced from the present investigation.
