Pyrolysis technology holds great potential for sustainable sewage sludge treatment due to its ability to recover energy, tackle the environmental challenges, and convert by-products into valuable resources. However, a comprehensive understanding of its research progression, sustainability implications, and policy relevance remains limited. This study offers a comprehensive analysis of sewage sludge (SS) pyrolysis research, integrating sustainability through life cycle assessment (LCA) and circular economy principles. Using Scopus and VOSviewer, it highlights significant growth in research, with publications rising in this decade, reflecting increasing global interest driven by environmental and technological imperatives. China dominates the field with 693 publications and extensive international collaborations, followed by the United States and Australia. Key journals play pivotal roles in disseminating findings, while interdisciplinary contributions span environmental science, energy, and chemical engineering. Keyword analysis reveals emerging trends such as circular economy, LCA, and carbon sequestration highlighting a growing focus on sustainable practices. LCA studies show that advanced pyrolysis technologies reduce greenhouse gas emissions, and align with United Nations Sustainable Development Goals. Circular economy analyses underscore the economic viability of co-pyrolysis, alongside substantial energy recovery and bio-oil market potential. Additionally, this study explores the key technological challenges and mitigation strategies crucial for optimizing SS pyrolysis systems and advancing future research. These findings underscore the adaptability of SS pyrolysis for waste valorization and its role in addressing environmental challenges. This analysis provides valuable insights for advancing research, informing policy, and optimizing industrial practices, highlighting SS pyrolysis as a critical technology for sustainable waste management and resource recovery

Modern U.S. dairies use antibiotics primarily for disease treatment and prevention. Consequently, antibiotic residues, antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARG) present in dairy manure may potentially enter the environment and contribute to the spread of antibiotic resistance (AR). Working cooperatively with 11 production dairies in three states (NY, PA, MD) our objective is to investigate the efficacy of existing on-farm manure management practices (e.g. long-term storage, composting, anaerobic digestion, etc.) at mitigating these potential contaminants. At each farm manure system performance is being assesses, antibiotic usage is being tracked, and manure samples are being collected at roughly 6-week intervals over 2-years pre- and post-each treatment step of the various manure handling systems. Samples are being analyzed for tetracycline, sulfonamide and macrolide antibiotic residues. Additionally, using culturing techniques and qPCR, ARB in manure solids before and after treatment are being quantified to study the effectiveness of bedding recovery systems at mitigating ARB pathogens. Select samples are also being analyzed for their diversity and abundance of ARGs. Preliminary data shows variable mitigation potentials of the different manure handling systems and is improving our understanding of the fate of these potential contaminants in dairy manures. As the project advances the efficacy of specific treatment systems to mitigate AR will be tested and knowledge on the fate of AR in dairy manure management systems will be extended to the dairy industry.

Navy ships must be able to operate anywhere in the world and visit any port unencumbered by environmental restrictions. The Office of the Chief of Naval Operations (OCNO) has formulated a vision for the environmentally sound ship of the 21st century, which will ensure compliance with environmental requirements applicable to Navy ships, while maintaining fleet effectiveness and readiness. Navy ships generate a variety of solid and liquid wastes and atmospheric emissions. Ships have limited capabilities for holding wastes for offload to shore. Working closely with the OCNO, the Naval Sea systems Command (NavSea) is developing systems, equipment, and procedures to process and manage ship wastes in an environmentally responsible manner. Several pieces of shipboard equipment have been successfully developed to process solid and liquid waste, hazardous materials and ozone-depleting substances (ODSs). The technologies and practices being developed under this program will: ensure compliance with environmental laws and regulations, significantly reduce the logistic burdens and costs associated with shoreside offload and disposal of ship wastes, implement Navy environmental and occupational safety and health policies, enhance the quality of life aboard ship, and continue the Navy's leadership role in protecting the marine environment.

NST support is provided principally in the form of grants awarded on a competitive basis under a rigorous peer review process; NSF does not conduct research itself. In 1992, NSF defined a project eligible for support as bioengineering research as one "...with diagnosis or treatment-related goals, that applies engineering principles to problems in biology and medicine while advancing engineering knowledge is eligible for support. Bioengineering research to aid persons with disabilities is also eligible". Bioengineering at NSF has two defined programs: 1. "Biochemical engineering", and 2. a two-component activity "Biomedical engineering" (BME) and "Research to Aid Persons with Disabilities" (RAPD). The material that follows describes the Undergraduate and Graduate Design Projects, which is part of the RAPD component of the bioengineering program.

Actuation Strategy of a Virtual Skydiver Derived by Reinforcement Learning

IFAC-PapersOnLine 2020年第2期53卷 1569-1574页

作者： Anna Clarke Per-Olof Gutman Technion Autonomous Systems Program Technion - Israel Institute of Technology Haifa 32000 Israel Faculty of Civil and Environmental Engineering Technion – Israel Institute of Technology Haifa 32000 Israel

An innovative approach of training motor skills involved in human body flight is proposed. Body flight is the art of maneuvering during the free fall stage of skydiving. The key idea is gradually constructing the movement patterns which are the combinations of body degrees-of-freedom that are activated synchronously and proportionally as a single unit, and turning this process into a coaching strategy. The proposed method is iterative: at each skill level an optimal movement pattern is constructed from the basic elements of the current movement repertoire. The free-fall maneuvers of each learning stage can be executed using any one of the basic elements. The construction has two stages: 1. tracking the desired maneuver while the body is actuated by each one of the basic patterns; 2. finding an optimal combination of these patterns to form a new way of body actuation. This hierarchical design resolves stage 2 by Reinforcement Learning with pure exploration and a minimal number of episodes. The method was tested in a Skydiver Simulator and resulted in deriving a movement pattern that showed a superior performance of the studied maneuver. The states and the reward of the Reinforcement Learning algorithm were converted into motor learning aids.

Visualization of highway traffic environments in virtual reality plays a key role on fidelity of simulation and validity of driving behaviors in driving simulator studies. This paper describes a procedure to replicate a signalized intersection with many complex features into a driving simulator's 3-D databases through building a graphical visual database, constructing a road motion database, and creating simulated traffic. The validity of the visualization was assessed via the comparison of the drivers' speeds in the simulator and the speed data at the real intersection. It was found that both speed data follow normal distributions and have equal means for each intersection approach;however, that the speeds measured in the driving simulator have a larger variability than those measured in the field. The users' subjective evaluation results indicated that 92% subjects could recognize the simulated intersection in the driving simulator experiment. Therefore, the strategy of geo-specific environment modeling would be useful for studying driving behaviors in virtual environments.

Soil gas samples from intact soil cores were collected on adsorbents at a field site, then thermally desorbed and analyzed by laboratory gas chromatography (GC). Vertical concentration profiles of predominant vapor phase petroleum hydrocarbons under ambient conditions were obtained for the zone directly above the capillary fringe. Water and residual phase weathered aviation gasoline were present in this region of the profile. The sampling, trapping, and GC methodology was effective in most respects. Reproducibility, trapping, and desorption efficiency were generally satisfactory, and different sorbent tubes gave similar results. A minor shortcoming of the method occurred with the most volatile compound, 2,3-dimethylbutane, which was poorly retained during several weeks of storage time and was also poorly desorbed. Vapor phase concentrations of predominant hydrocarbon compounds all increased with depth at one sampling location. At a more highly contaminated location, concentrations of highly volatile compounds increased with depth while concentrations of less volatile compounds remained constant or decreased, possibly indicating distillation effects. Scatter in the data was attributed to heterogeneities in water and residual phase distribution.

In this paper, we consider random sums with heavy-tailed increments. By the term random sum, we mean a sum of random variables where the number of summands is also random. Our interest is to construct an efficient method to calculate tail-based risk measures such as quantiles and conditional expectation (expected shortfalls). When assuming extreme quantiles and heavy-tailed increments, using standard Monte Carlo method can be inefficient. In previous works, there exists an efficient method to sample rare-events (tail-events) using a Markov chain Monte Carlo (MCMC) with a given threshold. We apply the sampling method to estimate statistics based on tail-information, with a given rare-event probability. The performance is compared with other methods by some numerical results in the case increments follow Pareto distributions. We also show numerical results with Weibull, and Log-Normal distributions. Our proposed method is shown to be efficient especially in cases of extreme tails. © 2014 SciTePress. All rights reserved.
