Recent Technical and Management Improvements in US Inland Waterway Transportation
(Routledge, part of the Taylor & Francis Group, 1999-07-01)
Over the last several years, the US inland waterway transportation industry has significantly reduced its fuel consumption and improved its efficiency, with the side effect of less fuel tax collected per ton of cargo ...
Options for Nonindigenous Species Control and Their Economic Impact on the Great Lakes and St. Lawrence Seaway: A Survey
(Society of Naval Architects and Marine Engineers (SNAME), 2003-01-01)
Nonindigenous species (NIS) cause substantial economic and ecological problems in the United States and other countries with marine trade. Current legislation and regulations require mandatory ballast water exchange for ...
An Improved Formulation for Bulk Cargo Ship Scheduling with a Single Loading Port
(Routledge, part of the Taylor & Francis Group, 2001-10-01)
This paper presents an improved, significantly more efficient formulation of an existing model for bulk cargo or semi-bulk cargo ship scheduling problems with a single loading port. The original model, published by Ronen ...
Aftertreatment control and adaptation for automotive lean burn engines with HEGO sensors
(John Wiley & Sons, Ltd., 2004-03)
Control of aftertreatment systems for lean burn technology engines represents a big challenge, due to the lack of on-board emission measurements and the sensitivity of the hardware components to ageing and sulphur poisoning. ...
Time-varying Ultimate Strength of Aging Tanker Deck Plate Considering Corrosion Effect
(Elsevier, 2008-10)
This paper presents a semi-probabilistic approach to assess the time-varying ultimate strength of aging tanker's deck plate considering corrosion wastage. The procedure includes (1) defining the limit state function of ...
New Models on the Ocean Acoustic Detection Process
(Acoustical Society of America, 1981-06)
The basic problem of the ocean acoustic detection process is formulated analytically under the assumption of fully developed saturated phase random multipath acoustic fluctuations. Detection is defined as occurring whenever ...
Improved methods for thin, surface boundary layer investigations
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-10)
New techniques are developed to improve the velocity flow-field measurement capability within a free-surface boundary layer region on which progressive capillary-gravity waves are present. Due to the extremely thin but ...
Visually Augmented Navigation for Autonomous Underwater Vehicles
(IEEE, 2008-04)
As autonomous underwater vehicles (AUVs) are becoming routinely used in an exploratory context for ocean science, the goal of visually augmented navigation (VAN) is to improve the near-seafloor navigation precision of such ...
An Overview of AUV Algorithms Research and Testbed at the University of Michigan
(IEEE, 2008-10-13)
This paper provides a general overview of the autonomous underwater vehicle (AUV) research projects being pursued within the Perceptual Robotics Laboratory (PeRL) at the University of Michigan. Founded in 2007, PeRL's ...
