Abstract
Purpose
The purpose of this paper is to present novel search formulations in gradient‐type methods for prediction of boundary heat flux distribution in two‐dimensional nonlinear heat conduction problems.
Design/methodology/approach
The performance of gradient‐type methods is strongly contingent upon the effective determination of the search direction. Based on the definition of this parameter, gradient‐based methods such as steepest descent, various versions of both conjugate gradient and quasi‐Newton can be distinguished. By introducing new search techniques, several examples in the presence of noise in data are studied and discussed to verify the accuracy and efficiency of the present strategies.
Findings
The verification of the proposed methods for recovering time and space varying heat flux. The performance of the proposed methods via comparisons with the classical methods involved in its derivation.
Originality/value
The innovation of the present method is to use a hybridization of a conjugate gradient and a quasi‐Newton method to determine the search directions in gradient‐based approaches.

Abstract
Purpose
The study considers a five-factor model toward online banking adoption in the context of banking customers in India and validates the proposed model. In addition, the authors consider the impact of validated factors on overall satisfaction of customers.
Design/methodology/approach
A five-factor online banking adoption model has been tested for reliability and validity by confirmatory factor analysis. For determining contribution of factors toward overall satisfaction level of banking customers structural equation modeling has been adopted. Four explanatory variables have been used to assess the overall satisfaction level of online banking users. A structured questionnaire incorporating variables identified from literature has been used as survey instrument for the study. Final respondent sample was 280 banking customers.
Findings
Trust, Usage Constraint, Ease of Use, Accessibility and Intention to Use as reliable and valid factors determining internet banking adoption among customers in India. Accessibility, Usage Constraints, Intention to Use portrayed strong and significant relationship with overall customer satisfaction. Trust and Ease of Use are relatively weaker and insignificant contributors toward overall customer satisfaction.
Originality/value
The existing studies in the context of e-banking in general and online banking in particular have been majorly confined to proposing key drivers toward adoption of such alternate banking mediums. By providing an insight towards satisfaction level of customers adopting online banking the proposed model attempts to fill this gap. As the study relates to banking customers in India, findings will be of particular value to domestic and foreign banking entities looking to leverage technology as a tool to attain stronghold with an emerging economic set-up.
