The problem of sewage and waste disposal from U. S. Navy ships is recognized by the highest authorities in the Navy. Many activities and individuals are deeply involved in the total problem and its numerous subcategories. The problem of costs of disposal is one of these. This paper discusses four optional methods for the disposal of shipboard domestic wastes. The annualized investment and operating costs associated with the implementation of each of the options are presented. The model considers non-nuclear, sea-going surface ships with a manning level greater than 50 men. Estimates were developed on a per ship per class basis and aggregated for the total surface fleet. This approach permits the inevstigation of different combinations of the options by merely specifying the number and type of ships to be considered in any option. Changes in military effectiveness, which is at least an equally important problem as costing, were not addressed.

Incorporating uncertainty assessment into hydrological simulation is of vital significance for providing valuable information for conserving and restoring the ecology environment in arid and semiarid regions. In this study, a sparse polynomial chaos expansions method was developed to quantify hydrological model parameter uncertainties on model performance in Kaidu river basin, China. A four dimension two order polynomial chaos expansions model was built and the effect of four parameters were quantified based on the coefficients of the polynomial chaos expansions model. Results indicated that precipitation in summer has more significant influence on model output than that in other seasons. High Sobol sensitivity indices values (0.22 in spring, 0.17 in summer, 0.21 in autumn and 0.29) for the interaction of precipitation and maximum capacity for fast store demonstrate that they are the major factors affecting runoff generation. These results can help reveal the flow processes and provide valuable information for water resources management.

ABSTRACTABSTRACTAll-terrain vehicle (ATV) crashes are one of the leading causes of death and injury in agriculture across the United States. Use of ATVs is highly prevalent in rural areas and has seen an increase in their application for a variety of agricultural work tasks. Empirical research on the use of these vehicles for agricultural tasks and associated injuries is limited, especially in the United States. Moreover, little is known about the risk factors associated with ATV-related injuries while doing farm work. A comprehensive review was conducted to evaluate the current injury burden of ATV use in agriculture, the need for future research, and possible solutions related to agricultural ATV safety. Potential injury prevention approaches are evaluated based on the hierarchy of control, including elimination or substitution (using side-by-side vehicles instead of ATVs or modifying ATV design), engineering control (operator protection devices), administrative authority (regulations and standards in the United States and around the world), training, and use of personal protective equipment. In addition, vehicle nomenclature, risk factors, and crash mechanisms are reviewed. Recommendations to decrease the likelihood of ATV crashes and injuries are provided.

Multimodal Transportation 2023年第4期2卷

作者： Mishra, Raunak Pulugurtha, Srinivas S. Mathew, Sonu Former Graduate Student of Infrastructure and Environmental Systems Ph.D. Program The University of North Carolina at Charlotte 9201 University City Boulevard Charlotte 28223-0001 NC United States Professor & Research Director of Civil & Environmental Engineering Department Director of Infrastructure Design Environment and Sustainability (IDEAS) Center The University of North Carolina at Charlotte 9201 University City Boulevard Charlotte 28223-0001 NC United States Post-Doctoral Researcher of IDEAS Center The University of North Carolina at Charlotte 9201 University City Boulevard Charlotte 28223-0001 NC United States

Growing population, rapid urbanization, and increasing travel demand emphasize the need for reliable public transportation systems and sustainable transportation planning. A reliable bus service fosters a more significant, satisfied, and committed base of users. This research focuses on examining the association between on-time performance (OTP) and road network, demographic, socioeconomic, and land use characteristics to identify relevant external factors for proactive and reliable public transportation system planning. The analysis was conducted at a bus stop level. Bus arrival/departure data from the Charlotte Area Transit System (CATS) was obtained. The road network, demographic, socioeconomic, and land use characteristics were captured within 0.25-mile and 0.50-mile buffers. Pearson correlation analysis was conducted to understand the association between OTP and road network, demographic, socioeconomic, and land use characteristics by day of the week and time of the day. The results show that OTP is associated with external factors such as the number of signalized or cul-de-sac/dead-end intersections, number of lanes, network density, population, income (median and total), and land use types related to residential and commercial/employment purposes within the bus stop vicinity. The findings provide vital insights for transit agencies to enhance scheduling, service and maximize benefits, effectively utilize available resources, plan, and provide equitable services to all riders. © 2023 The Author(s)

To evaluate the reliability of information technology equipment under various thermal and air-pollution conditions, a mechanistic model based on multi-ion transport and chemical reactions was developed. The model was used to predict Cu corrosion caused by Cl2-containing pollutant mixtures. It also accounted for the effects of temperature (25°C and 28°C), relative humidity (50%, 75%, and 95%), and synergism. It also identified higher air temperature as a corrosion barrier and higher relative humidity as a corrosion accelerator, which agreed well with the experimental results. The average root mean square error of the prediction was 13.7 Å. © 2023, The Authors. All rights reserved.

NAVAL ENGINEERS JOURNAL 1997年第3期109卷 385-393页

作者： Vaughters, TG Mardiros, MF Theodore G. Vaughters:has more than thirty years of engineering and program management experience in the development and testing of material handing hardware systems to transfer cargo from ship-to-shore from ship-to-ship and within both Navy and commercial ships. From 1967 to 1977 he was a supervisory naval architect at Hunters Point Naval Shipyard and Mare Island Naval Shipyard. In 1977 he joined his present organization and became office head in 1987. He has received numberous awards including the Meritorious Civilian Service Award for the management of a program which development a Ro/Ro ship offshore unloading facility. His department is currently engaged in a number of RDT&E logistics program which include environmental ligistics Navy logistics modeling and simulation mobile offshore bases sea based logistics strategic sealift joint service ligistics over the shore systems underway replenishment and shipboard cargo handling systems. Martin F. Mardiros:has been working on JLOTS related systems for eight years as a engineer at the Naval Surface Warfare Center Carderock Division. He has a B.S.E. degree in naval architecture from the University of Michigan He has participated in numberous JLOTS and JLOTS related exercises since 1988. Mr Mardiros has fielded a evaluation of full scale prototype sea state 3 JLOTS systems for evaluation and demonstration such as the Air Cushion Vehicle Landing Platform (ACVLAP) improved mooring and fendering systems for causeway ferries and motion mitigation sytems for the Roll-On/Roll-Off Discharge Facility. Mr. Mardiros recently headed up the JLOTS Sea State 3 Option Study which is being used by the Navy and Army to develop their JLOTS master plan.

Joint Logistics Over the Shore (JLOTS) operations involve the unloading of ships without the benefit of fixed port facilities. Container ships, roll-on/roll-off (Ro/Ro) ships, break bulk ships, heavy lift ships, and tankers are the most common merchant vessels utilized in JLOTS operations to transport military cargo. A major problem is that the current JLOTS system is inoperative in sea state 3 and greater conditions. When seas build above sea state 3 the motion and relative motion of lighters and ships create extremely dangerous conditions which preclude the movement of cargo. New technology is currently being developed by the Navy, Army and the Defense Advanced Research Projects Agency (DARPA) to improve JLOTS operations. Several new JLOTS subsystems were recently tested as part of an Office of the Secretary of Defense (OSD) sponsored joint services test and evaluation program called JLOTS III (June 1993). JLOTS III showed that lighters, cargo transfer systems, and personnel do not have the capability or training to perform in sea state 3, as currently required by military doctrine. Subsequent to the JLOTS III testing, a number of R&D innovations have been examined and a Heavy Weather (Sea State 3) JLOTS Options Study has been completed. This options study has defined and characterized all the weak links related to heavy weather operations and has identified and/or developed concepts to improve the overall JLOTS operational efficiency. This paper discusses current JLOTS technology development initiatives from a joint services perspective with regard to the following question: Can emerging technology, in combination with improved training and command and control, provide a heavy weather JLOTS capability which is affordable?

The quantity of information on nanomaterial properties and behavior continues to grow rapidly. Without a concerted effort to collect, organize and mine disparate information coming out of current research efforts, the value and effective use of this information will be limited at best. Data will not be translated to knowledge. At worst, erroneous conclusions will be drawn and future research may be misdirected. Nanoinformatics can be a powerful approach to enhance the value of global information in nanoscience and nanotechnology. Much progress has been made through grassroots efforts in nanoinformatics resulting in a multitude of resources and tools for nanoscience researchers. In 2012, the nanoinformatics community believed it was important to critically evaluate and refine currently available nanoinformatics approaches in order to best inform the science and support the future of predictive nanotechnology. The Greener Nano 2012: Nanoinformatics Tools and Resources Workshop brought together informatics groups with materials scientists active in nanoscience research to evaluate and reflect on the tools and resources that have recently emerged in support of predictive nanotechnology. The workshop goals were to establish a better understanding of current nanoinformatics approaches and to clearly define immediate and projected informatics infrastructure needs of the nanotechnology community. The theme of nanotechnology environmental health and safety (nanoEHS) was used to provide real-world, concrete examples on how informatics can be utilized to advance our knowledge and guide nanoscience. The benefit here is that the same properties that impact the performance of products could also be the properties that inform EHS. From a decision management standpoint, the dual use of such data should be considered a priority. Key outcomes include a proposed collaborative framework for data collection, data sharing and information integration. © 2013 IOP Publishing Ltd.

The historical analytical data collected at Murdock demonstrate that: Constitutent concentrations in ground water in the area of highest known contaminant concentrations and along the flow path downgradient of that area decreased over the 3.5-year period when we began monitoring at the site and when we conducted the biogeochemical study. The ground water plume has stabilized and will not move further south. Chlorinated hydrocarbon parent products (TCE and 1,1,1-TCA) are degrading to their daughter products (1,1-DCA, 1,1-DCE, and cis-1,2-DCE) and thence to VC. The estimated total mass of chlorinated hydrocarbons dissolved in ground water was reduced from 1032 to 346 pounds between 1993 and the end of 1996 (approximately 66%). However, the scoring from the AFCEE protocol showed that there was only 'limited' evidence of biological dechlorination occurring at the site.
