Abstract The rise of offshore marginal field development and low-cost CAPEX has given an impetus to O&G operators to challenge the common structural platform design especially for wellhead platform type. Demand to reduce the platform weight has been observed for the past 20 years. Typically, the challenge to meet this demand will be tremendous once the water depth exceed 50m. This paper will elaborate on how using an engineered design approach was implemented to obtain fast track onshore fabrication and offshore installation and meet the operator demand for minimal structural concept.

Tunable Lens

The electromagnetic (EM) properties of metasurfaces depend on both structural design and material properties. microelectromechanical systems (MEMS) technology offers an approach for tuning metasurface EM properties by structural reconfiguration. In the past 10 years, vast applications have been demonstrated based on MEMS metasurfaces, which proved to have merits including, large tunability, fast speed, small size, light weight, capability of dense integration, and compatibility of cost-effective fabrication process. Here, recent advances in MEMS metasurface applications are reviewed and categorized based on the tuning mechanisms, operation band and tuning speed. As an example, the pros and cons of MEMS metasurfaces for tunable lens applications are discussed and compared with traditional tunable lens technologies followed by the summary and outlook.

Pivoting Friction

This paper expounds on the deviation of measured coefficient of friction from the assignment when the friction pair of the spherical bearing changes from plane structure into spherical structure, and summarizes the common explanation of such phenomenon of the past. Through the analysis on the methods of the measurement test for the coefficient of spherical pivoting friction and an in-depth analysis on the relation between the motion state and relative motion of the internal parts of the spherical bearing generated by rotating it based on this method, a new calculation formula for the coefficient of pivoting friction of the spherical bearing is put forward, which is of great significance to in-depth understanding of the structural principles of spherical bearing, precise structural design and sound bearing applications.

Higher Education Costs

Over the past decade due the expansion of globalization there has been an increasing emphasis on internationalization among faculty, administration and accrediting agencies in the Higher Education.  Although to promote internationalization in the Higher Education, costs are a big challenge, one way to have the international actions with low cost, it is seeking for grants from different governmental agencies and foundations.The Fulbright Scholar program provides a long-standing and externally-funded means for internationalizing college and university curriculum. This article is going to share the perspective   of a Brazilian Fulbright Scholar at an American college and the institution perspective of the Fulbright scholar participation at the College.

Abstract Current demands by the consumer, the automobile industry, and the environment have determined the basis of this investigation. In the past, the requirements—ever faster, ever sportier—were accepted as decisive parameters for the development of our study. In the future, rational and safety-related tire characteristics as well as environmental consciousness will increase, whereas purely performance-related parameters will diminish in their importance. Through our light-weight tire project, we have paved the way for future tire generations. The first priority is the minimal use of material resources; this means a reduction of materials and energy in tire production by using advanced design and production methods without sacrificing performance standards. This benefits the consumer—the final judge of all of our activities—by considerably reducing the rolling resistance, leading to lower fuel consumption. Further design targets include the improvement of rolling behavior and increased comfort by reducing tire weight, and therefore a reduction in unsprung masses on the vehicle.

A low-cost wastewater disposal system was commissioned in 1959 to treat domestic and industrial wastewaters generated in the Latrobe River valley in the province of Gippsland, within the State of Victoria, Australia (Figure 1). The Latrobe Valley is the centre for large-scale generation of electricity and for the production of pulp and paper. In addition other industries have utilized the brown coal resource of the region e.g. gasification process and char production. Consequently, industrial wastewaters have been dominant in the disposal system for the past twenty-five years. The mixed industrial-domestic wastewaters were to be transported some eighty kilometres to be treated and disposed of by irrigation to land. Several important lessons have been learnt during twenty-five years of operating this system. Firstly the composition of the mixed waste stream has varied significantly with the passage of time and the development of the industrial base in the Valley, so that what was appropriate treatment in 1959 is not necessarily acceptable in 1985. Secondly the magnitude of adverse environmental impacts engendered by this low-cost disposal procedure was not imagined when the proposal was implemented. As a consequence, clean-up procedures which could remedy the adverse effects of twenty-five years of impact are likely to be costly. The question then may be asked - when the total costs including rehabilitation are considered, is there really a low-cost solution for environmentally safe disposal of complex wastewater streams?
