In order to establish an objective method of evaluating pillow comfort, we investigate the relation between the sensory evaluation of pillows and the compression properties of pillows. The subjective evaluation values of hardness, fitness and total comfort were correlated with the compression energy WC and the displacement Δ T at the maximum load of 50gf/cm². Pillows which have large values of WC and Δ T were regarded as softer, fitter and more comfortable. Pillows estimated as being soft and fit showed larger contact areas and less contact pressure on the head. For the pillows which have the same flat shape, a good agreement between the individual judges was shown in the assessments of hardness and height. The shape and packing density of polyethylene pipes affected the degree of the hardness of the pillows.

If an electric current i flows in a metal in the direction of the temperature‐gradient dT―dx' or in the inverse direction, then besides Joule's heat an evolution or an absorption of heat takes place in the metal. This phenomena is called Thomson effect, and the heat‐quantity thus evolved or absorbed Thomson‐heat. Thom‐son‐heat W generated during time t in unit volume of the metal is given by the following expression:

Relationships have been investigated between subjective pressure sensation and objective pressure measured, for knit garments of different sizes and fabrics with different extensibilities. Fechner's logarithmic law is used to investigate the relations. Equations are obtained for describing the Psychophysical mechanism of clothing pressure perception under certain conditions. Objective pressure measuring had high predictive power with regard to subjective pressure sensation only under those conditions. Wearing pressure comfort has a negative correlation with feelings of fetter, scratchy, heavy and pressure, and has a poor correlation with feelings of softness and smoothness. Using factor analysis with principal factor solutions and rotated by the Varimax method, we obtained factor matrices.

This techno-centric and too much busy day-to-day living style of citizens pressurizes the implementation of E-ticketing service to adapt with change. Thus, this study aims to examine the factors influencing railway passengers’ E-ticketing service acceptance and usage intention in Bangladesh and to extend the widely used Technology Acceptance Model through inserting two new constructs.

This paper employs structural equation modeling to test model’s paths developed through theoretical research framework. Moreover, a structured questionnaire was administered at different railway stations in northern and western parts of Bangladesh to collect data. Total of 302 responses were considered for statistical analysis to test hypotheses after considering anomalies and outliers in raw data.

The study results show that technology trust (TT) has the strongest impact on passengers’ E-ticketing usage intention rather than perceived ease of use and perceived usefulness (PU). Meanwhile, the easiness of using technology to reserve tickets does matter to female passengers rather than male passengers wherein PU and TT do not do that.

The findings of this study might be helpful for the railway authorities to improve the ticket reservation service quality online by developing the advanced booking application and minimizing the pressure on other transportation. Therefore, this empirical study will contribute to this domain for further study that ensures full satisfaction of passengers and uplift the railway passengers’ usage intention for E-ticketing which then helps the government to implement the digitization slogan with efficiency and effectiveness.
