He serves as the Chair of the Joint ASNE/SNAME Committee on Environmental Engineering and also as Chair of ASTM Ships and Marine Technology Marine Environmental Protection Subcommittee (F25.06).

Regulations governing the discharge of sewage from ships have been in force since the early 1970's. In response, the marine industry has developed ever more complex systems and processes for managing these wastes. The first compliance method involved holding wastes until they could be legally discharged;as technology advanced, treatment systems were developed and installed to enable discharge within regulated waters. As the size and number of ships as increased with maturation of the ocean tourism business, more restrictive regulations have been enacted to minimize the impact on sensitive waters. The trend is toward increasing regulation of both sewage and graywater. The most recent action occurred on 12 October 2005 when the Governor of California signed into law Senate Bill 771 regulating most ship liquid discharges within state waters. This paper describes the development of an innovative advanced wastewater treatment technology, based on advanced oxidation, bearing in mind the lessons learned from systems developed by industry over the past thirty years.

Zeolite micropattern created from structurally similar hydrophobic Sil-1 and hydrophilic ZSM-5 zeolites, and tested for the immobilization of fluorescein isothiocyanate conjugate bovine serum albumin (BSA-FITC), biotin conjugate bovine serum albumin (Biotin-BSA), Hochest 33342 and rhodamine conjugate α- bungatoxin, were preferentially deposited onto hydrophobic ZSM-5 patterns regardless of the pattern geometry. Being inorganic, the zeolite micropattern does not deteriorate with time and can be readily reused by simply burning away the deposited chemicals and biomolecules. This suggests that compositional micropattern of zeolite could be used to create high resolution array of biomolecules on flat substrate.

The height supplied by the GPS system is merely mathematics. In most studies the height shall be referred to the Geoid. With a sufficient number of Level References with known horizontal and vertical coordinates it is almost always adjusted by polynomials of Least Squares Method that allow the interpolation of geoidal undulations. These polynomials are inefficient when extrapolating the data outside the study area. Thus the aim of this work is to present a new method for modeling the surface of Local Geoid based on the technique of Artificial Neural Networks. The study area is the Hydrological Basin of Rio dos Sinos which is located in Rio Grande do Sul State -Brazil and for the training of the neural network undulations data supplied by the MAPGEO2004 program was used. The program was developed by the Instituto Brasileiro de Geografia e Estatística (Brazilian Institute of Geography and Statistics) with an absolute error band bigger than 0.5 meter. Even with such a big error, the data supplied by MAPGEO2004 can be used in the training of a neural network, because it is tolerant to errors and noises. The efficiency of the model was tested in 8 points with known undulations and distributed throughout the study area. On these points the model has presented, through calculated discrepancies, a root mean square error of 0.170 meter, approximately. The study shows that this method can be an alternative in modeling local and/or regional Geoid.

The NANOOS-Pilot project (Northwest Association of Networked Ocean Observing Systems) is an ongoing effort to develop coastal ocean observing assets for the integrated observation of the estuaries and shorelines of the Pacific Northwest. The project is actively building nowcast and predictive capabilities for this environment, as well as interactive access to archival data, real-time data, and selected forecasts. In addition to the potential benefits accrued to the many sectors that depend upon the coastal waters of the Pacific Northwest, there are a number of education opportunities related to ocean observatories involving undergraduate and graduate institutions, K-12 schools and adult literacy programs. In this work, we describe some ocean technology applications of the NANOOS-Pilot and focus on the educational use of the system in a senior-level Civil engineering course on Coastal Infrastructure. © American Society for engineering Education, 2006.

Attracting high school students to college engineering programs has been recognized as a challenge by several engineering organizations. One of the reasons for the low percentage enrolment of high school graduates into engineering programs is that many math/science teachers and counselors lack understanding of engineering applications within the subjects they teach and prospects associated with engineering careers. The instruction at the school level is often criticized for not adequately emphasizing science and mathematics, especially connections with engineering applications. Many students have difficulty connecting math and science courses to common phenomena seen all around and to future careers. This problem is further aggravated on Indian reservations in North Dakota because of their isolated locations and distance from industries. The authors developed a weekend academic program, "Sunday Academy", carried out on four North Dakota Indian reservations, to stimulate Native American students' interest in science, technology, engineering, and mathematics (STEM), to attract to engineering programs, and to engage high school teachers and tribal college instructors in the process of developing engineering and applied science lesson plans. The academy consisted of a series of one-day academic sessions presented monthly to junior and senior high school students. The lesson plans for the sessions were developed collaboratively by a group of university and community college faculty and high school teachers. This project provided unique opportunities for engineering professors to work with high school students directly, to familiarize high school teachers and tribal college instructors with engineering concepts and approaches, and to be knowledgeable about and sensitive to Indian culture. To make it a successful program, the authors had to overcome various challenges, including selection of lesson topics and hands-on activities that are interesting and suitable for the st

Various techniques of autostereoscopic three-dimensional (3D) display for displaying real 3D information have been investigated in recent years. We have performed research and application of integral videography (IV), which is an animated display technique based on the principle of integral photography (IP). Although IV and IP are ideal ways to display 3D images, their spatial viewing resolution and high-speed image rendering algorithm must be improved. The pixel pitch of the display and the lens pitch are the main factors affecting IV image quality. We improved the image quality by increasing the number and density of the pixels. Parallel image processing and displaying method were also developed for animated IV imaging. We have created a scalable high-resolution image using multiple projection and project it onto a small screen to achieve high-density pixels using long-focal-length projection optics. Furthermore, an image calibration method was developed for geometrical correction and color modulation to generate seamless IV images. We evaluated the developed device by displaying an X-ray computed tomography (CT) image. Measurement of the geometrical accuracy of the reproduced IV images demonstrated that the spatial resolution of the display system matched that by theoretical analysis. Experimental results showed that our technique is very effective in obtaining 3D animated images with practical spatial resolution. © 2006 Wiley Periodicals, Inc.
