Assessment of Power System Reliability by Marko Čepin Pdf

The importance of power system reliability is demonstrated when our electricity supply is disrupted, whether it decreases the comfort of our free time at home or causes the shutdown of our companies and results in huge economic deficits. The objective of Assessment of Power System Reliability is to contribute to the improvement of power system reliability. It consists of six parts divided into twenty chapters. The first part introduces the important background issues that affect power system reliability. The second part presents the reliability methods that are used for analyses of technical systems and processes. The third part discusses power flow analysis methods, because the dynamic aspect of a power system is an important part of related reliability assessments. The fourth part explores various aspects of the reliability assessment of power systems and their parts. The fifth part covers optimization methods. The sixth part looks at the application of reliability and optimization methods. Assessment of Power System Reliability has been written in straightforward language that continues into the mathematical representation of the methods. Power engineers and developers will appreciate the emphasis on practical usage, while researchers and advanced students will benefit from the simple examples that can facilitate their understanding of the theory behind power system reliability and that outline the procedure for application of the presented methods.

Reliability Assessment of Electric Power Systems Using Monte Carlo Methods by Billinton,W. Li Pdf

The application of quantitative reliability evaluation in electric power sys tems has now evolved to the point at which most utilities use these techniques in one or more areas of their planning, design, and operation. Most of the techniques in use are based on analytical models and resulting analytical evaluation procedures. Improvements in and availability of high-speed digi tal computers have created the opportunity to analyze many of these prob lems using stochastic simulation methods and over the last decade there has been increased interest in and use made of Monte Carlo simulation in quantitative power system reliability assessment. Monte Carlo simulation is not a new concept and recorded applications have existed for at least 50 yr. However, localized high-speed computers with large-capacity storage have made Monte Carlo simulation an available and sometimes preferable option for many power system reliability applications. Monte Carlo simulation is also an integral part of a modern undergrad uate or graduate course on reliability evaluation of general engineering systems or specialized areas such as electric power systems. It is hoped that this textbook will help formalize the many existing applications of Monte Carlo simulation and assist in their integration in teaching programs. This book presents the basic concepts associated with Monte Carlo simulation.

Handbook of Research on Determining the Reliability of Online Assessment and Distance Learning by Moura, Ana S.,Reis, Pedro,Cordeiro, M. Natália D. S. Pdf

Though in the past online learning was considered of poorer professional quality than classroom learning, it has become a useful and, in some cases, vital tool for promoting the inclusivity of education. Some of its benefits include allowing greater accessibility to educational resources previously unattainable by those in rural areas, and in current times, it has proven to be a critical asset as universities shut down due to natural disasters and pandemics. Examining the current state of distance learning and determining online assessment tools and processes that can enhance the online learning experience are clearly crucial for the advancement of modern education. The Handbook of Research on Determining the Reliability of Online Assessment and Distance Learning is a collection of pioneering investigations on the methods and applications of digital technologies in the realm of education. It provides a clear and extensive analysis of issues regarding online learning while also offering frameworks to solve these addressed problems. Moreover, the book reviews and evaluates the present and intended future of distance learning, focusing on the societal and employer perspective versus the academic proposals. While highlighting topics including hybrid teaching, blended learning, and telelearning, this book is ideally designed for teachers, academicians, researchers, educational administrators, and students.

Reliability Assessment of Large Electric Power Systems by Roy Billinton,Ronald N. Allan Pdf

We are very pleased to be asked to co-author this book for a variety of reasons, one of which was that it gave us further opportunity to work together. The scope proposed was very wide with the only significant proviso being that the book should be in a mongraph-style and not a teaching text. This require ment has given us the opportunity to compile a wide range of relevant material relating to present-day knowledge and application in power system reliability. As many readers will be aware, we have collaborated in many ways over a relatively long period and have co-authored two other books on reliability evaluation. Both of these previous books were structured as teaching texts. This present book is not a discourse on "how to do reliability evaluation" but a discussion on "why it should be done and what can be done and achieved" and as such does not replace or conflict with the previous books. The three books are complementary and each enhances the others. The material contained in this book is not specifically original since it is based on information which we have published in other forms either jointly or as co authors with various other people, particularly our many research students. We sincerely acknowledge the important contributions made by all these students and colleagues. There are too many to mention individually in this preface but their names appear frequently in the references at the end of each chapter.

Validity and Inter-Rater Reliability Testing of Quality Assessment Instruments by U. S. Department of Health and Human Services,Agency for Healthcare Research and Quality Pdf

The internal validity of a study reflects the extent to which the design and conduct of the study have prevented bias(es). One of the key steps in a systematic review is assessment of a study's internal validity, or potential for bias. This assessment serves to: (1) identify the strengths and limitations of the included studies; (2) investigate, and potentially explain heterogeneity in findings across different studies included in a systematic review; and (3) grade the strength of evidence for a given question. The risk of bias assessment directly informs one of four key domains considered when assessing the strength of evidence. With the increase in the number of published systematic reviews and development of systematic review methodology over the past 15 years, close attention has been paid to the methods for assessing internal validity. Until recently this has been referred to as “quality assessment” or “assessment of methodological quality.” In this context “quality” refers to “the confidence that the trial design, conduct, and analysis has minimized or avoided biases in its treatment comparisons.” To facilitate the assessment of methodological quality, a plethora of tools has emerged. Some of these tools were developed for specific study designs (e.g., randomized controlled trials (RCTs), cohort studies, case-control studies), while others were intended to be applied to a range of designs. The tools often incorporate characteristics that may be associated with bias; however, many tools also contain elements related to reporting (e.g., was the study population described) and design (e.g., was a sample size calculation performed) that are not related to bias. The Cochrane Collaboration recently developed a tool to assess the potential risk of bias in RCTs. The Risk of Bias (ROB) tool was developed to address some of the shortcomings of existing quality assessment instruments, including over-reliance on reporting rather than methods. Several systematic reviews have catalogued and critiqued the numerous tools available to assess methodological quality, or risk of bias of primary studies. In summary, few existing tools have undergone extensive inter-rater reliability or validity testing. Moreover, the focus of much of the tool development or testing that has been done has been on criterion or face validity. Therefore it is unknown whether, or to what extent, the summary assessments based on these tools differentiate between studies with biased and unbiased results (i.e., studies that may over- or underestimate treatment effects). There is a clear need for inter-rater reliability testing of different tools in order to enhance consistency in their application and interpretation across different systematic reviews. Further, validity testing is essential to ensure that the tools being used can identify studies with biased results. Finally, there is a need to determine inter-rater reliability and validity in order to support the uptake and use of individual tools that are recommended by the systematic review community, and specifically the ROB tool within the Evidence-based Practice Center (EPC) Program. In this project we focused on two tools that are commonly used in systematic reviews. The Cochrane ROB tool was designed for RCTs and is the instrument recommended by The Cochrane Collaboration for use in systematic reviews of RCTs. The Newcastle-Ottawa Scale is commonly used for nonrandomized studies, specifically cohort and case-control studies.

Reliability and Validity of International Large-scale Assessment by Anonim Pdf

This open access book describes and reviews the development of the quality control mechanisms and methodologies associated with IEA's extensive program of educational research. A group of renowned international researchers, directly involved in the design and execution of IEA's international large-scale assessments (ILSAs), describe the operational and quality control procedures that are employed to address the challenges associated with providing high-quality, comparable data. Throughout the now considerable history of IEA's international large-scale assessments, establishing the quality of the data has been paramount. Research in the complex multinational context in which IEA studies operate imposes significant burdens and challenges in terms of the methodologies and technologies that have been developed to achieve the stated study goals. The demands of the twin imperatives of validity and reliability must be satisfied in the context of multiple and diverse cultures, languages, orthographies, educational structures, educational histories, and traditions. Readers will learn about IEA's approach to such challenges, and the methods used to ensure that the quality of the data provided to policymakers and researchers can be trusted. An often neglected area of investigation, namely the consequential validity of ILSAs, is also explored, examining issues related to reporting, dissemination, and impact, including discussion of the limits of interpretation. The final chapters address the question of the influence of ILSAs on policy and reform in education, including a case study from Singapore, a country known for its outstanding levels of achievement, but which nevertheless seeks the means of continual improvement, illustrating best practice use of ILSA data.--

Clinical Assessment of Child and Adolescent Personality and Behavior by Paul J. Frick,Christopher T. Barry,Randy W. Kamphaus Pdf

Psychologists offer an increasing variety of services to the public. Among these services, psychological assessment of personality and behavior continues to be a central activity. One main reason is that other mental health professionals often do not possess a high level of competence in this area. And when dealing with children and adolescents, psychological assessment seems to take on an even greater role. Therefore, it follows that comprehensive graduate-level instruction in assessment should be a high priority for educators of psychologists who will work with these youth. This textbook is organized into three sections, consistent with the authors’ approach to teaching. Part I provides students with the psychological knowledge base necessary for modern assessment practice, including historical perspectives, measurement science, child psychopathology, ethical, legal, and cultural issues, and the basics of beginning the assessment process. Part II gives students a broad review of the specific assessment methods used by psychologists, accompanied by specific advice regarding the usage and strengths and weaknesses of each method. In Part III, we help students perform some of the most sophisticated of assessment practices: integrating and communicating assessment results and infusing assessment practice with knowledge of child development and psychopathology to assess some of the most common types of behavioral and emotional disorders in youth. A text focusing on assessment practices must be updated every four to six years to keep pace with advances in test development. For example, several of the major tests reviewed in the text, such as the Behavioral Assessment System for Children and the Child Behavior Checklist, have undergone major revisions since the publication of the last edition making the current content outdated. Further, another major test, the Conners’ Rating Scales, is undergoing substantial revisions that should be completed before publication of the next edition. Finally, the evidence for the validity of the tests and the recommendations for their appropriate use evolve as research accumulates and requires frequent updating to remain current. For example, there was a special issue of the Journal of Clinical Child and Adolescent Psychology published focusing on evidenced-based assessment of the major forms of childhood psychopathology that will need to be integrated into the chapters in Part 3. This latter point reflects an important trend in the field that should influence the marketing of the book. That is, there are several initiatives being started in all of the major areas of applied psychology (e.g., school, clinical, and counseling) to promote evidenced-based assessment practices. These initiatives have all emphasized the need to enhance the training of graduate students in this approach to assessment. This has been the orientation of this textbook from its first edition: that is, Clinical Assessment of Child and Adolescent Personality and Behavior has focused on using research to guide all recommendations for practice. The ability of the textbook to meet this training need should be an important focus of marketing the book to training programs across all areas of applied psychology.

A Guide To Practical Human Reliability Assessment by B. Kirwan Pdf

Human error is here to stay. This perhaps obvious statement has a profound implication for society when faced with the types of hazardous system accidents that have occurred over the past three decades. Such accidents have been strongly influenced by human error, yet many system designs in existence or being planned and built do not take human error into consideration.; "A Guide to Practical Human Reliability Assessment" is a practical and pragmatic guide to the techniques and approaches of human reliability assessment HRA. lt offers the reader explanatory and practical methods which have been applied and have worked in high technology and high risk assessments - particularly but not exclusively to potentially hazardous industries such as exist in process control, nuclear power, chemical and petrochemical industries. A Guide to Practical Human Reliability Assessment offers the practitioner a comprehensive tool-kit of different approaches along with guidance on selecting different methods for different applications. It covers the risk assessment and the HRA process, as well as methods of task analysis, error identification, quantification, representation of errors in the risk analysis, followed by error reduction analysis, quality assurance and documentation. There are also a number of detailed case studies from nuclear, chemical, offshore, and marine HRA'S, exemplfying the image of techniques and the impact of HRA in existing and design-stage systems.

Solder Joint Reliability Assessment by Mohd N. Tamin,Norhashimah M. Shaffiar Pdf

This book presents a systematic approach in performing reliability assessment of solder joints using Finite Element (FE) simulation. Essential requirements for FE modelling of an electronic package or a single reflowed solder joint subjected to reliability test conditions are elaborated. These cover assumptions considered for a simplified physical model, FE model geometry development, constitutive models for solder joints and aspects of FE model validation. Fundamentals of the mechanics of solder material are adequately reviewed in relation to FE formulations. Concept of damage is introduced along with deliberation of cohesive zone model and continuum damage model for simulation of solder/IMC interface and bulk solder joint failure, respectively. Applications of the deliberated methodology to selected problems in assessing reliability of solder joints are demonstrated. These industry-defined research-based problems include solder reflow cooling, temperature cycling and mechanical fatigue of a BGA package, JEDEC board-level drop test and mechanisms of solder joint fatigue. Emphasis is placed on accurate quantitative assessment of solder joint reliability through basic understanding of the mechanics of materials as interpreted from results of FE simulations. The FE simulation methodology is readily applicable to numerous other problems in mechanics of materials and structures.

Children's Reading Comprehension and Assessment by Scott G. Paris,Steven A. Stahl Pdf

Originating in a recent CIERA conference held at the University of Michigan, this book brings together the nation's most distinguished researchers to examine how readers understand text and how comprehension is assessed. The first part provides both national and historical contexts for the study of reading comprehension. The second part examines how vocabulary, motivation, and expertise influence comprehension, and it includes analyses of the developmental course and correlates of comprehension. Chapters in the third part consider how schools focus on comprehension for instruction and assessment. The fourth part includes chapters on large-scale assessment that analyze how test formats and psychometric characteristics influence measures of reading comprehension. At the end of each part is a commentary--written by an expert--that reviews the chapters, critiques the main points, and synthesizes critical issues. Key features of this outstanding new book include: *Integration of Research and Practice--provides a bridge between conceptual issues studied by researchers concerned with reading comprehension theories and practical issues addressed by educators concerned with classroom instruction and assessment. *Comprehension Focus--provides a thorough history and rigorous research-based analyses of reading comprehension. *Assessment Focus--provides innovative approaches to comprehension assessment that include the influences of vocabulary, decoding, and motivation. *Synthetic Commentaries--provides periodic summaries that analyze and synthesize research, practices, and issues discussed in each part. *Expertise--contributing authors and commentators are highly respected authorities on reading comprehension (see table of contents). This text is appropriate for educational and psychological researchers, reading educators, and graduate students in education and psychology. It is part of the CIERA series, which includes the following volumes: Taylor and Pearson: Teaching Reading: Effective Schools, Accomplished Teachers (2002) Van Kleeck, Stahl, and Bauer: On Reading Books to Children: Parents and Teachers (2003) Hoffman and Schallert: The Texts in Elementary Classrooms (2005)
