This book was released on 2004 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Utilities often experience difficulty planning and designing distribution systems to meet spatial water demands. Water system demand characteristics (quantity, quality, timing, and location) drive many distribution system management, operation, and design decisions. Characteristics such as average-annual use, maximum-day use, maximum-hour use, and fire-flow requirements constrain the makeup, size, and timing of distribution system modifications and expansions. Although sophisticated network models are often used to design and analyze distribution system modifications and expansions, these models traditionally treat nodal demand characteristics as a fixed parameter. In many cases, the spatial distribution of water demand is not well defined.The goals of the project were to * assess existing tools and methodologies used for identification, prediction, and spatial allocation of water demands for distribution system planning and design * make use of state-of-the-art technologies, water consumption data, and other regional data to develop improved empirical depictions of the spatial distribution of water demand * develop common tools and methodologies for predicting and allocating demand in water distribution planning and design models * describe methods for quantifying uncertainties associated with water demand predictions that are used for system planning and design. The project produced practical approaches to working with utility consumption data for developing spatial demand allocation in water distribution modeling and system planning. Furthermore, the researchers introduced innovative statistical methods (e.g., robust statistics, continuous time functional form, and fixed effects methodology). The researchers also explained the potential applications of spatial demand allocation to distribution planning.

Download or read book Predictive Models for Water Quality in Distribution Systems written by J. Clement and published by American Water Works Association. This book was released on 2005-04-30 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are two groups of specialists involved in the development and application of water quality models, each of which have a different perspective on the use of models: Academics and scientists - chemistry specialists and microbiologists who develop the models. Practitioners - modelers and distribution engineers who use them to solve problems. There are limitations and constraints in the characterization of the underlying processes and the practical application of models to distribution networks, which require further research. The objectives of the research were to characterize the current state of predictive distribution system water quality models and to identify critical research needs for their improvement. The project reviewed both the development and application of models. The report is intended to both steer future research and to act as a general reference on water quality modeling. The report combines a literature review with the practical experience of the project team. The content of a draft report was discussed at an international workshop attended by academics, engineers, scientists, and hydraulic modelers with the objective of agreeing on specific research needs necessary to improve predictive modeling for water quality in distribution systems. The conclusions of the report are derived from the workshop and form the basis of 11 specific research briefs that have been submitted to AwwaRF for consideration of funding. Researchers often focus on modeling the individual processes that control water quality rather than fully modeling water quality throughout distribution systems. For these "process models" to be applied to real distribution networks, they need to be extended to take in account the physical characteristics of the system?the special and temporal variations in flow, velocity and water age, and the effects of mixing water that has traveled along different flow paths.

This book was released on 2012-09-09 with total page 1804 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the PSE community continues its focus on understanding, synthesizing, modeling, designing, simulating, analyzing, diagnosing, operating, controlling, managing, and optimizing a host of chemical and related industries using the systems approach, the boundaries of PSE research have expanded considerably over the years. While early PSE research was largely concerned with individual units and plants, the current research spans wide ranges of scales in size (molecules to processing units to plants to global multinational enterprises to global supply chain networks; biological cells to ecological webs) and time (instantaneous molecular interactions to months of plant operation to years of strategic planning). The changes and challenges brought about by increasing globalization and the the common global issues of energy, sustainability, and environment provide the motivation for the theme of PSE2012: Process Systems Engineering and Decision Support for the Flat World. Each theme includes an invited chapter based on the plenary presentation by an eminent academic or industrial researcher Reports on the state-of-the-art advances in the various fields of process systems engineering Addresses common global problems and the research being done to solve them

This book was released on 2018-02-28 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing complexity of work systems and changes in the nature of workplace technology over the past century have resulted in an exponential shift in the nature of work activities, from physical labor to cognitive work. Modern work systems have many characteristics that make them cognitively complex: They can be highly interactive; comprised of multiple agents and artifacts; information may be limited and distributed across space and time; task goals are frequently ill-defined, conflicting, dynamic and emergent; planning may only be possible at general levels of abstraction or require adaptive solutions; some degree of proficiency or expertise is required; the stakes are often high; and uncertainty, time-constraints and stress are seldom absent. To complicate matters further, cognition in complex work settings is typically constrained by broader professional, organizational, and institutional practice and policy. These features of cognitive work present significant challenges to scientific methodology and theory, and subsequent design of reliable interventions. Historically, philosophers and scientists have attempted to understand the mental activities experienced during cognitive work at multiple levels of analysis using divergent methods. Some have examined cognition at an associative, contextual, functional or holistic level, relying on naturalistic methods to understand the higher mental processes as they work in harmony during goal-directed behavior. Others have embraced experimental methods and favored internal over external validity, often reducing cognition to a psychology of fundamental acts, such as short-term memory access with millisecond shifts in attention. More recently, Macrocognition has evolved as a complementary paradigm. Macrocognitive researchers have studied the cognitive functions and processes associated with skilled, adaptive, collaborative, and resilient cognitive work in the context of the aforementioned complexities of psychotechnical and sociotechnical work systems. Typically, this research has been carried out using cognitive task analytic techniques that draw on both naturalistic and (quasi-)experimental methods. The primary goals of research in Macrocognition are to better understand cognitive adaptations to complexity, to increase our theoretical understanding of the organism-environment relations by studying the mapping between cognitive work and real-world demands, and to promote use-inspired research capable of improving system performance.
