Available in PDF, EPUB and Kindle. Book excerpt: This book celebrates the dawn of the rye genomics era with concise, comprehensive, and accessible reviews on the current state of rye genomic research, written by experts in the field for students, researchers and growers. To most, rye is the key ingredient in a flavoursome bread or their favourite American whisky. To a farmer, rye is the remarkable grain that tolerates the harshest winters and the most unforgiving soils, befitting its legacy as the life-giving seed that fed the ancient civilisations of northern Eurasia. Since the mid-1900s, scientists have employed genetic approaches to better understand and utilize rye, but only since the technological advances of the mid-2010s has the possibility of addressing questions using rye genome assemblies become a reality. Alongside the secret of its unique survival abilities, rye genomics has accelerated research on a host of intriguing topics such as the complex history of rye’s domestication by humans, the nature of genes that switch fertility on and off, the function and origin of accessory chromosomes, and the evolution of selfish DNA.

Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive Water Quality and Purification, Four Volume Set provides a rich source of methods for analyzing water to assure its safety from natural and deliberate contaminants, including those that are added because of carelessness of human endeavors. Human development has great impact on water quality, and new contaminants are emerging every day. The issues of sampling for water analysis, regulatory considerations, and forensics in water quality and purity investigations are covered in detail. Microbial as well as chemical contaminations from inorganic compounds, radionuclides, volatile and semivolatile compounds, disinfectants, herbicides, and pharmaceuticals, including endocrine disruptors, are treated extensively. Researchers must be aware of all sources of contamination and know how to prescribe techniques for removing them from our water supply. Unlike other works published to date that concentrate on issues of water supply, water resource management, hydrology, and water use by industry, this work is more tightly focused on the monitoring and improvement of the quality of existing water supplies and the recovery of wastewater via new and standard separation techniques Using analytical chemistry methods, offers remediation advice on pollutants and contaminants in addition to providing the critical identification perspective The players in the global boom of water purification are numerous and varied. Having worked extensively in academia and industry, the Editor-in-Chief has been careful about constructing a work for a shared audience and cause

Available in PDF, EPUB and Kindle. Book excerpt: Abstract Failure Predicting Model for Oil Pipelines Bassem Abdrabou Oil and gas pipelines are considered the safest means to transport petroleum products comparing to railway and highway transportations. They transport millions of dollars{u2019} worth of goods every day. However, accidents happen every year and some of these accidents inflict catastrophic impact on the environment and result in great economic loss. In order to maintain safety of the pipelines, several inspection techniques have been developed in the last decades. Despite the accuracy of these techniques, they are very costly and time consuming. Similarly, several failure predicting and condition assessment models have been developed in the last decade; however, most of these models are limited to one type of failure, such as corrosion failure, or mainly depend on expert opinion which makes their output seemingly subjective. The present research develops an objective model of failure prediction for oil pipelines depending on the available historical data on pipelines' accidents. Two approaches were used to fulfill this objective: the artificial neural network (ANN) and the Multi Nomial Logit (MNL). The ANN is used to develop a model to predict failure due to mechanical, corrosion or third party, which collectively account for 88% of oil pipeline accidents. This model had a prediction accuracy of 68.5%. Another ANN model is developed to predict only corrosion or third party failure with a prediction accuracy of 72.2%. The Average Validity Percentage (AVP) for the two models is 73.7 and 72.8, respectively. The MNL approach is used to develop a model that predicts failures caused by mechanical, corrosion or third party elements with a prediction accuracy of 68.4% and Pseudo R Squared of 0.42. The Average Validity Percentage (AVP) for this MNL approach is 73.7%. This model also generates a probability equation for each type of failure. The three developed models show convincing results, since they are based on solid historical failure data for the last 38 years, with no subjectivity or ambiguity. These models could easily be used by oil pipeline operators to identify the type of failure threatening each pipeline so that appropriate preventive and corrective measures can be planned. The models also help to prioritize in-line inspection of different pipeline segments according to the predicted type of failure.

Book excerpt: With an evolutionary advancement of Machine Learning (ML) algorithms, a rapid increase of data volumes and a significant improvement of computation powers, machine learning becomes hot in different applications. However, because of the nature of “black-box” in ML methods, ML still needs to be interpreted to link human and machine learning for transparency and user acceptance of delivered solutions. This edited book addresses such links from the perspectives of visualisation, explanation, trustworthiness and transparency. The book establishes the link between human and machine learning by exploring transparency in machine learning, visual explanation of ML processes, algorithmic explanation of ML models, human cognitive responses in ML-based decision making, human evaluation of machine learning and domain knowledge in transparent ML applications. This is the first book of its kind to systematically understand the current active research activities and outcomes related to human and machine learning. The book will not only inspire researchers to passionately develop new algorithms incorporating human for human-centred ML algorithms, resulting in the overall advancement of ML, but also help ML practitioners proactively use ML outputs for informative and trustworthy decision making. This book is intended for researchers and practitioners involved with machine learning and its applications. The book will especially benefit researchers in areas like artificial intelligence, decision support systems and human-computer interaction.

Download or read book Failure Prediction and Availability-based Maintenance Planning of Gas Transmission Pipelines written by Kimiya Zakikhani and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the most frequent failure source, external corrosion has led to more than 1700 failures in gas transmission pipelines in US since 1996, causing a property damage of approximately $189M. Such numbers highlight the importance of maintaining gas transmission pipelines in safe conditions to postpone corrosion failures. As the most widely applied method of corrosion monitoring technique, in-line inspection is expensive and time-consuming due to requiring high frequencies. On the other hand, the recent efforts directed towards developing failure prediction or maintenance planning models for oil and gas pipelines seem to have some limitations. As such, most of the failure prediction models are based on limited number of inspection or historical records or are limited in application due to their subjectivity. Furthermore, in the domain of maintenance planning, the current procedures are merely based on considering the associated costs and safety thresholds in the decision-making process. Such methodologies do not address the importance of pipeline availability and continuation of operation as a critical asset in the selection of the maintenance strategy. This research has two main objectives. As the first objective, the proposed research aims to develop historical data-based failure prediction models for gas transmission pipelines by considering geo-environmental features. As the second objective, this research aims to propose a reliability-centered availability-based maintenance planning framework that considers the criticality of pipeline operation. For these objectives, a detailed literature review was carried out on current methodologies to predict failures in oil and gas pipelines and maintain them. As the most important limitations, current failure prediction models do not consider geographical and environmental properties of pipelines to predict failures. On the other hand, in maintenance planning scope, none of current practices highlight importance of pipeline operation and availability in making the proper decision. In addition, these methodologies are often subjective, i.e. they are merely applicable to limited pipelines. To overcome these limitations the mentioned objectives of this research were defined and failure and maintenance data were collected from accessible historical records and reports. The failure prediction models were developed from best-subset and multiple regression analyses on the historical failure data and were then validated. On the other hand, the maintenance planning framework was developed from a coupled cost and availability-based maintenance planning procedure on different maintenance scenarios. For each scenario, a discrete event simulation was carried out through MATLAB programming. Such simulation was performed on the pipeline reliability profile obtained from a Monte Carlo simulation and consideration of improvement in availability per unit cost as the decision criteria. Monte Carlo simulation was carried out to consider wide range of design parameters for development of the reliability profile. The developed failure prediction models were able to satisfactory predict time of corrosion failures in gas transmission pipelines for Great Plains and South East Regions of the U.S. These models were validated with mean absolute error (MAE) and root mean square error (RMSE) of 0.12 and 0.04, for Great Plains, and 0.11 and 0.07, for South East regional classifications, respectively. The proposed maintenance planning framework reveals that for a case study of a 24-inch pipeline, considering an availability-cost indicator, the second maintenance scenario, with interventions at the service life of 30.1 and 40.5 years is more effective. This order is followed by the first scenario with interventions at service life of 33.3 and 42.2 years, and finally the third scenario with intervention at service life of 24.2 years, respectively. The developed failure prediction models can assist decision makers and pipeline operators to predict the expected time of corrosion failure in gas transmission pipelines in the selected regions by considering geo-environmental and pipeline design parameters. In addition, for maintenance planning of oil and gas pipelines, this research proposes a novel methodology that considers oil and gas pipelines as critical assets for which continued operation is of high importance. Such consideration provides a compensation between the costs incurred and pipeline availability to avoid over/under maintenance.

Available in PDF, EPUB and Kindle. Book excerpt: This conference provides a forum for exchange of technical and operational information across a wide range of pipeline activities. Various supply and distribution industries, and their service organisations, have traditionally approached pipeline systems from many different perspec tives. The organisers believe that significant benefits can be gained by enabling representatives from the oil, gas, water, chemical, power and related industries to present their latest ideas and methods. An awareness of these alternative methodologies and technologies should result in a more unified and coherent approach to each individual type of pipeline system. The overall theme of the conference is the optimisation of pipeline systems, through design analysis, component specification, operational strategies and performance evaluation, in order to minimise both risk and the lifetime cost of ownership. Wherever possible emphasis is given to important developing technologies with special consideration to use of computational equipment and methods. SYSTEMS APPROACH For the major activities of design, operation and performance; pipeline systems can be conveniently classified in terms of the systetV: components, constraints and objectives. These are described using fluid terminology, to suit' the majority of conference participants, as given below: Components consist of pumps and valves (controls), pipe networks (transmission and distribu tion), reservoirs (storage) and consumer demands (disturbances). The arrangement of these components, to form the system, must take into account the conflicting requirements of structural, hydraulic, and cost, performance.
