The United States Merchant Marine Academy is one of the five United States service academies. It is charged with training officers for the United States Merchant Marine, branches of the military, or the transportation industry.Midshipmen are trained in marine engineering, navigation, ship's administration, maritime law, personnel management, international law, customs, and many other subjects important to the task of running a large ship.

Uncertainty is a major issue facing electric utilities in planning and decision making. Modeling uncertainty can be based on the approach called "Unknown but Bounded" in which upper and lower limits on the uncertainties are assumed without probability distributions. Interval mathematics provides a tool for the practical implementation and extension of the unknown but bounded concept. The calculation of transmission line sag and inductance are used as examples to illustrate the use of interval mathematics. The purpose of sag calculations is to determine the change in cable length, given a fixed span and an interval of cable sag values, for numerous variations in temperature. The resulting change in cable length will therefore be an interval corresponding to the interval of cable sag values. Inductance values are also calculated using the traditional single point numbers as well as interval numbers. The values from these two methods are compared to prove the validity of interval analysis. © 2012 IEEE. Source

Results are presented from experiments and computational fluid dynamics (CFD) simulations involving the streamlining of suspended underwater pipelines or structures subject to impacts from sediment/water mixtures. The experiments showed that a considerable reduction in force may be achieved by streamlining, and this reduction in force is most significant at lower Reynolds numbers. Several shapes were tested: round, airfoil, and wedge. Of these, the wedge exhibited the lowest drag coefficient-about one-fifth of the cylindrical pipe at low values of the Reynolds number, and about half at higher Reynolds numbers. © 2012 American Society of Civil Engineers.

The United States Merchant Marine Academy's (USMMA) Master of Science in Marine Engineering (MMaeR) program is celebrating its 10th anniversary in 2015. MMaeR was conceived, developed, and implemented by Professor Jose Femenia, who was at that time, department head of the USMMA. The first entering class was limited to alumni of USMMA and the six state maritime academies, to help provide for a focused program. In 2008, admission was opened to applicants not processing an undergraduate background in marine engineering. MMaeR is a 36-credit, 12-course program offered through a blending of online synchronous and asynchronous sessions to deliver the course content. Courses are offered year-round using traditional semester timeline. Six of the seven core classes address the principle topics of particular interest to marine engineers. The program's online delivery enables students to continue their professional careers while pursuing higher education. Source

Driven by globalization and the Chinese export-oriented economy, ports in China have experienced exponential growth in the past decade. The Chinese port industry has gone through several stages of reform, from a central-control system with inadequate investment and poor efficiency to a large-scale and highly competitive system with various types of public-private partnerships. Today, the Chinese port industry is characterized by rapid growth, large-scale foreign investment, and liberalization of port policy. Of the top 10 container ports in the world, six are in China. This accomplishment is largely because of port reforms; in recent years, corporatization and joint venture have become the hallmark of port development in China. This study reviewed the evolution of China's port reform and policy changes supported by port statistics, examined a brief case study of port development in Shanghai, China, and analyzed policy changes in port governance, legal framework, and funding mechanisms. The analysis integrated key milestones in policy change and port development. Port reform has become an enabler of China's economic development and international trade. The unique model of port governance and administration provides an effective tool for macrocontrol at the national level and private-sector investment in cargo-handling systems and management expertise. Whether the port reform will take the next step toward more private sector involvement and what type of public-private partnership will form remain to be seen. Source

Simulation of the flow and deposition from a laboratory turbidity current, in which dense mixtures of sediment move down a narrow, sloping channel and flow into a large tank. SSIIM CFD software is used to model 3-D flow and deposition. SSIIM predicts the height of the accumulated mound to within 25% of experimental values, and the volume of the mound to 20%~50%, depending on the concentration of sediment and slope of the channel. The SSIIM predictions were consistently lower than experimental values. In simulations with initial sediment volumetric concentrations greater than 14%, SSIIM dumped some of the sediment load at the entry gate into the channel, which was not the case with the experimental runs. This is likely due to the fact that the fall velocity of sediment particles in SSIIM does not vary with sediment concentration. Further simulations of deposition from turbidity currents should be attempted when more complete experimental results are available, but it appears for now that SSIIM can be used to give approximate estimates of turbidity current deposition. © 2010 Harbin Engineering University and Springer Berlin Heidelberg.
