An Investigation into the Mediating Influence of Customer Expertise on the Antecedents and Consequences of Affect within Professional Service Markets

This study examines the mediating influence of consumer expertise on the antecedents and consequences of Affect within a professional services market context. Whilst there is increasing evidence to suggest an empirical link between Affect evoked and satisfaction within such contexts, previous research has largely ignored the role of consumer expertise as a mediating influence. Using a scenario based approach, the objective of the study was to test for multigroup invariance among competing structural models based on the ability of the respondents to form expectation and performance assessments about the service they are receiving. The results indicate that it is important to examine different levels of consumer expertise in detail to better understand how certain characteristics such as experience and qualifications influence the priority and functionality attached to service attributes when making satisfaction judgments within a professional service context. This may in turn have broader implications for our contextual understanding of services

Mathematical theory of electrical networks.

In this thesis an attempt has been made to present a mathematical model of an electrical network based on Kron's work and further to use this model, for analyzing electrical network problems. To begin with, we shall represent an electrical network as a linear graph. The electrical network problem is presented in an abstract topological form, and the condition on the property of branch impedance matrix for the unique existence of the solution is developed. The various contradictions of the linear graph model are then pointed out. To remove these contradictions, a topological model, consisting of branches only, which is called the branch network or 1-network by Kron is introduced. The various concepts of 1-networks are generalized to any dimension p. The properties of p-networks are described with the help of elementary concepts of algebraic topology. Finally, diakoptic and co-diakoptic property of p-network is described as a direct outcome of p-network theory

Fluid-structural interaction with application to rocket engines

International audienceThe objective of this work is to develop a finite element model for studying fluid–structure interaction. The geometrically non-linear structural behaviour is considered and based on large rotations and large displacements. An arbitrary Lagrangian–Eulerian (ALE) formulation is used to represent the compressible inviscid flow with moving boundaries. The structural response is obtained using Newmark-type time integration and fluid response employs the Lax–Wendroff scheme. A number of numerical examples are presented to validate the structural model, moving mesh implantation of the ALE model and complete fluid–structure interaction

Not AvailableAlliums are widely consumed as food and medicine but modestly understood for their genetic constitution and design. Huge, complex and repetitive genomes, biennial life cycle, strong inbreeding depression and apomixes have thwarted development of optimal genotypes, especially in the third world. However, genetic diversity assessment, markerassisted breeding, introgression of some vital genes, doubled haploid production, induction of fertility in apomicts, organellar transcriptome sequences, gene annotation and genetic engineering have been achieved to certain extent and continue to develop further. In this review, current achievements in these areas of research for enhancing yield, processing quality, therapeutic value, storage and biotic stress resistance in important edible Allium species have been compiled.Not Availabl
