The California Maritime Academy is one of 23 campuses in the California State University system and is one of only seven degree-granting maritime academies in the United States and the only one on the west coast. It is located in Vallejo, California. The university offers six different Bachelor's degrees, and one Master's degree, but no Doctoral degrees. Wikipedia.

Low dielectric constant materials play a key role in modern electronics. In this regard, hollow particle reinforced polymer matrix composites called syntactic foams may be useful due to their low and tailored dielectric constant. In the current study, vinyl ester matrix/glass hollow particle syntactic foams are analyzed to understand the effect of hollow particle wall thickness and volume fraction on the dielectric constant of syntactic foams. The dielectric constant is found to decrease with increase in the hollow particle volume fraction and decrease in the wall thickness. Theoretical estimates are obtained for the dielectric constant of syntactic foams. Parametric studies are conducted using the theoretical model. It is found that a wide range of syntactic foam compositions can be tailored to have the same dielectric constant, which provides possibility of independently tailoring density and other properties based on the requirement of the application. © 2013 Springer Science+Business Media New York.

A collection of applications of polymer matrix syntactic foams is presented in this article. Syntactic foams are lightweight porous composites that found their early applications in marine structures due to their naturally buoyant behavior and low moisture absorption. Their light weight has been beneficial in weight sensitive aerospace structures. Syntactic foams have pushed the performance boundaries for composites and have enabled the development of vehicles for traveling to the deepest parts of the ocean and to other planets. The high volume fraction of porosity in syntactic foams also enabled their applications in thermal insulation of pipelines in oil and gas industry. The possibility of tailoring the mechanical and thermal properties of syntactic foams through a combination of material selection, hollow particle volume fraction, and hollow particle wall thickness has helped in rapidly growing these applications. The low coefficient of thermal expansion and dimensional stability at high temperatures are now leading their use in electronic packaging, composite tooling, and thermoforming plug assists. Methods have been developed to tailor the mechanical and thermal properties of syntactic foams independent of each other over a wide range, which is a significant advantage over other traditional particulate and fibrous composites. © 2013 The Minerals, Metals & Materials Society.

A combined basis of analytic Gaussian functions and grid-based finite element-discrete variable representation spherical harmonic expansion is specialized for the description of continuum electron dynamics in the presence of electrons held fixed in core molecular orbitals. The applicability of this hybrid representation designed for general problems involving accurate determination of molecular continua wave functions is illustrated for photoionization of second-row diatomic molecules. Accurate descriptions of such electron continuum dynamics are a necessary step towards analyzing correlated double continua photoejections. Examination of this hybrid method in comparison to a more computationally expensive pure grid-based single-center expansion reveals several key advantages that by design make it attractive for describing processes involving one or more electrons moved to the continuum. © 2014 American Physical Society.

An emerging class of materials that are hybrid in nature is propelling a technological revolution in energy, touching many fundamental aspects of energy-generation, storage, and conservation. Hybrid materials combine classical inorganic and organic components to yield materials that manifest new functionalities unattainable in traditional composites or other related multicomponent materials, which have additive function only. This Research News article highlights the exciting materials design innovations that hybrid materials enable, with an eye toward energy-relevant applications involving charge, heat, and mass transport. Hybrid materials are a key class of emerging compounds in which organic and inorganic components are united to produce materials with new capabilities. This is in distinct contrast to composite materials that have additive functionality only. Recent advances in the field are reviewed, which show the broad impact hybrids will have on applications ranging from electronics, heat transfer, and mass transport. © 2015 WILEY-VCH Verlag GmbH & Co.

While human rights protection has been promoted on land with greater or lesser degrees of success, there is little conversation about human rights at sea at the national, international or corporate level. A number of recent security developments in the maritime domain such as maritime piracy and its impact on seafarers and those who protect them, human trafficking at sea, illegal migration, and human slavery in some maritime industries have raised this issue to greater prominence. Consequently, there is a need for highlighting human rights issues towards the end of protecting and respecting individual human rights in the maritime context, as well as mitigating and providing remedies for "human rights violations in the daily running of the maritime industry and for workers in the maritime environment." © 2014 Australian Maritime College, an institute of the University of Tasmania.
