Psychological and cultural insights into consumption of luxury western brands in India
No full textIndia has always had wealthy elites such as the maharajas, upper class and royalty that consume luxury products throughout its consumption history. The relatively recent economic rise of the middle class with an increase in disposable income is leading to consumption of luxury en mass. This qualitative study examines why consumers buy luxury, what they believe luxury is and how their perception of luxury impacts buying behaviour in the context of India. The present study explores luxury constructs drawn from the literature and provides some explanation for luxury consumption behaviour in India. The findings reveal that psychological and cultural factors in Indian society play a major part in shaping luxury consumption. While the findings suggest little support for homogenous luxury preference, Indian consumers share cultural characteristics of lavish consumption of luxury and display of wealth in social functions. Luxury reflects conspicuous consumption and status, and signals wealth for individuals, and conveys social identity and status in Indian society

Diagnostics and prognostics with acoustic emission, vibration and spectrometric oil analysis for spur gears; a comparative study
No full textWhilst vibration and spectrometric oil analysis for gear fault diagnosis are
well established, the application of AE to this field is still in its infancy.
This paper describes an experimental investigation on spur gears in which
natural pitting was allowed to occur. Throughout the test period, AE, vibration
and spectrometric oil samples were monitored continuously in order to correlate
and compare these techniques to natural life degradation of the gears. It was
observed that the AE technique was the most sensitive in detecting and
monitoring pitting

Effect of lateral pipe-soil interaction on controlled lateral buckling using pre-deformed pipeline
No full textA novel approach to eliminate the onset of global buckling in pipelines is investigated in the paper. The method is based on pre-deforming a pipeline continuously with a specific wavelength and amplitude prior to installation on the seabed. The response of the pipeline to applied high temperature and pressure was studied in conjunction with variations in the lateral pipe-soil interaction (PSI) – both as uniform friction along the pipe and also with locally varying friction. Pipe and seabed parameters representing a typical wet-insulated infield flow line on soft clay are used. The pre-deformed pipeline has a higher buckle initiation temperature compared to a straight pipeline due to the reduced effective axial force build-up resulting from the low axial stiffness generated by the predeformed lobes along the pipeline. The results from this paper show that the strains in the predeformed pipeline are not significantly affected by the local variability of lateral PSI but rather by the global mean PSI. At a typical lateral soil resistance, i.e. a friction coefficient of 0.5, lateral buckling occurs at a very high temperature level that is not common in the subsea operation. At a very low friction, i.e. 0.1, lateral buckling occurs at a lower operating temperature but the strain is insignificant. The longitudinal strain of the pipeline is not highly sensitive to the lateral PSI, which is a quite different response to an initially straight pipeline. Therefore, this method could prove to be a valuable tool for the subsea industry as it enables the pipeline to be installed and operated safely at very high temperatures without the need for lateral buckling design and installation of expensive structures as buckle initiators. Even if the pre-deformed pipeline buckles at a very high temperature, during cycles of heat-up and cool-down the buckle shape ‘shakes down’ by geometric rearrangement to minimize the energy, and in doing so creates a series of ‘short pipelines’ in which the longitudinal strain is self-controlled. The system is therefore shown to be very robust in the conditions investigated and not affected by one of the biggest unknowns in seabed pipeline engineering, which is the local variability in lateral PSI
Effect of initial Out-of-Straightness (OOS) on predeformed pipeline for controlling lateral buckling
No full textA novel method of controlling lateral buckling, which involves pre-deforming a pipeline continuously into specific wavelength and amplitude prior to installation on the seabed, is reported in this paper. This paper first introduces the concept of pre-deforming pipe and then presents the results of FE analysis of different initial pre-deformation shapes that can influence the buckling behaviour of this pipeline system. Several random distributions of out-of-straightness are applied along the predeformed pipeline to investigate the sensitivity of the system to one of the largest uncertainty factors in pipeline designs – the exact as-laid configuration. Results show that with suitable selection of an initial pre-deformed shape and dimension, the system will only buckle at temperature and pressure levels that are unrealistically high for currently developed gas fields. It is found that both the buckle initiation load and the longitudinal strain are not sensitive to the inherent distribution of OOS. This makes a continuously pre-deformed pipeline a reliable, robust and safe lateral buckling management system. <br/
Controlling lateral buckling of subsea pipeline with sinusoidal shape pre-deformation
No full textIt is common for subsea pipelines to operate at high pressures and high temperatures (HPHT) conditions. The build-up of axial force along the pipeline due to temperature and pressure differences from as-laid conditions coupled with the influence of the seabed soil that restricts free movement of the pipeline can result in the phenomenon called ‘lateral buckling’. The excessive lateral deformation from lateral buckling may risk safe operation of the pipeline due to local axial strains that potentially could be severe enough to cause fracture failure of welds or collapse of the pipeline. Engineered buckles may be initiated reliably during operation by using special subsea structures or lay methods which are expensive. This paper introduces and exemplifies a novel method that involves continuously deforming the pipeline prior to or during installation with prescribed radius and wavelength to control lateral buckling that could be a valuable modification of the practical design of offshore pipelines. Previous published work has shown that installation of a pipeline with such continuous deformations is feasible. The results from an example pipeline case described here show that the pipeline can be installed and operated safely at elevated temperatures without the need for other expensive buckle initiation methods.</p
