The present paper presents the analysis, carried out by the Ocensa pipeline, against a case of longitudinal or axial landslide to the pipeline in the KM 35 + 690, starting from the identification by inertial tool, the geotechnical characterization and the analysis of Soil-pipe interaction, excavation and stress relief and the techniques used to mitigate the effects of sliding on the pipe.

A large portion of infrastructure was flooded by water running off pavements or overflowing from the drainage systems in Fiji. The main objectives of this study are to identify the most suitable drainage management solution to reduce the overflow of the drainage system in Fiji, and to develop a framework of drainage management systems. The literature review was conducted to identify various drainage systems used to mitigate flooding around the world. After the review, the characteristics of Fiji such as climate pattern, location and soil type were analysed in the case study section. Secondary data which was obtained from Australia, Norway, the Netherlands, the U.S., Korea, and China were used in the research. The characteristics of Fiji were then mapped to other countries and a scoring system was created to analyse the suitability of different flood mitigation techniques in Fiji. Finally, multiple flood management strategies were proposed, and a drainage management framework for flood mitigation was developed.

This work is part of a multidisciplinary project developing design and manufacturing methods for narrow-gauge surgical instruments intended for advanced minimally invasive surgery. The instruments are designed specifically for Penn State’s lost mold rapid infiltration forming process, which is capable of fabricating hundreds of freestanding meso-scale parts. In previous work, a 1 mm diameter forceps case study demonstrated the design and fabrication process. The forceps is a monolithic compliant mechanism (CM) that relies on contact to re-distribute maximum stresses to generate larger elastic tip deflections; a phenomenon defined here as contact stress-relief. Prototypes were developed and evaluated in an end user surgical simulator. Feedback from 11 clinicians identified the total jaw opening of the forceps must be increased in the next generation of prototypes. This paper focuses on exploiting the benefits of contact-aided compliant mechanism (CCM) design to obtain larger elastic tip deflections and thus jaw openings. Using the commercially available finite element software package ANSYS to model large deformation and contact, an optimization problem is developed to determine the effects of incorporating additional contact elements in a CCM design on maximizing elastic tip deflection. Results show that designs with multiple contact elements generate larger elastic tip deflections due to a multi-stage contact stress-relief profile.
