In polymer composites, the porosity acts mainly as a stress concentrator, which has detrimental effects depending on the shape and position of the voids. Also, the presence of voids is detrimental to the mechanical properties, which results in the need for an accurate method for their characterization in terms of morphology, position, and volume fraction. The aim of this study was to establish an appropriate procedure for the measurement of voids in a polymer composite using the mercury porosimetry technique. Data were also collected using the Taguchi approach. Subsequently, the feasibility of applying the Hg porosimetry methodology was confirmed through a comparison with standard techniques. Statistical analysis was used to determine the best Hg porosimetry parameters and pressures between 203 and 231 MPa was found to generate reliable results for the maximum porosity measurement, with no dependence on other parameters. Since the Hg porosimetry, acid digestion, and optical microscopy methods provided porosity results with a statistically significant similarity, it can be concluded that all these methods are feasible for the analysis of voids. Finally, potential benefits of the proposed porosity analysis methodology were highlighted through the characterization of the void volume, position, and morphology. POLYM. ENG. SCI., 2020.

This note aims to address the concerns and confusions raised by Jakub et al. (2020) on the article of Zhang and Meng published in Ocean Engineering in 2019. Zhang and Meng (2019) mainly proposed the probabilistic ship domain to capture the diverse navigational behaviors of captains based on the big AIS data with less emphasies on how to assess ship collision risk using the probabilistic ship domain. To achieve of the aim, we first examine two concepts of ideal ship domain and practical ship domain. We proceed to investigate the relationship between ship domain and ship collision risk using field data from restricted water in both Singapore strait and fairway. We finally discuss the onboard collision detection by using the probabilistic ship domain incorporating with the Closest Point of Approach (CPA). This note not only clarifies some confusions or misunderstandings of the applicaion of probabilistic ship domain for ship collision risk assessment bust also exhibits the values and merits of the probabilistic ship domain.
