This book was released on 2021-09-01 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the research background and significance of carbon emissions in the tunnel industry and systematically reviewed the research progresses of carbon emission researches for tunnels, LCA (life cycle assessment) research framework, and uncertainty research progress. The authors propose a novel modular carbon emission calculation method for highway tunnel construction and expounds on the modular LCA system boundary theory of tunnel construction. This method does not require abundant knowledge of LCA modeling, which is convenient for general engineering and technical personnel to calculate the carbon emission level of tunnel construction. The calculation formulas for input and carbon emissions of each module are provided. It also analyzes the parameter uncertainty, model uncertainty, and scenario uncertainty of the carbon emissions from tunnel construction by the Monte Carlo method. Further, this book proposes the fitting model of carbon emissions of unit engineering quantity in tunnel construction, which benefits to simplify the calculation of carbon emissions.This book is mainly aimed at engineering and technical personnel in the construction industry, especially tunnel and underground engineering, including tunnel design engineers; tunnel construction engineers, experts, and scholars; tunnel owners; management departments.

Download or read book Improving food composition data by standardizing calculation methods written by Öhrvik, Veronica and published by Nordic Council of Ministers. This book was released on 2015-09-02 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food composition data is important in nutritional policy making. However, food analyses are expensive and to use analysed values only is not economically justifiable; hence recipe calculations are important for the quality of food composition databases. The aim with this project, financed by the Nordic Council of Ministers, was to improve and standardize the recipe calculation method. A general recipe calculation method was developed, implemented and validated by comparing analysed and calculated content. The method and the foods recalculated within the project will be used in national dietary surveys and are available to the public through the national food composition databases. This report may be used as a guide through recipe calculations. Furthermore, the importance of well-structured methods for recipe calculations and possible consequences otherwise are highlighted.

Download or read book Methods and Applications of Sample Size Calculation and Recalculation in Clinical Trials written by Meinhard Kieser and published by Springer Nature. This book was released on 2020-11-19 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an extensive overview of the principles and methods of sample size calculation and recalculation in clinical trials. Appropriate calculation of the required sample size is crucial for the success of clinical trials. At the same time, a sample size that is too small or too large is problematic due to ethical, scientific, and economic reasons. Therefore, state-of-the art methods are required when planning clinical trials. Part I describes a general framework for deriving sample size calculation procedures. This enables an understanding of the common principles underlying the numerous methods presented in the following chapters. Part II addresses the fixed sample size design, where the required sample size is determined in the planning stage and is not changed afterwards. It covers sample size calculation methods for superiority, non-inferiority, and equivalence trials, as well as comparisons between two and more than two groups. A wide range of further topics is discussed, including sample size calculation for multiple comparisons, safety assessment, and multi-regional trials. There is often some uncertainty about the assumptions to be made when calculating the sample size upfront. Part III presents methods that allow to modify the initially specified sample size based on new information that becomes available during the ongoing trial. Blinded sample size recalculation procedures for internal pilot study designs are considered, as well as methods for sample size reassessment in adaptive designs that use unblinded data from interim analyses. The application is illustrated using numerous clinical trial examples, and software code implementing the methods is provided. The book offers theoretical background and practical advice for biostatisticians and clinicians from the pharmaceutical industry and academia who are involved in clinical trials. Covering basic as well as more advanced and recently developed methods, it is suitable for beginners, experienced applied statisticians, and practitioners. To gain maximum benefit, readers should be familiar with introductory statistics. The content of this book has been successfully used for courses on the topic.

Download or read book Calculation of Nonlinear Conical Flows by the Method of Lines written by E. B. Klunker and published by . This book was released on 1971 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computational technique, called the method of lines, is developed for computing the flow field about conical configurations at incidence in a supersonic flow. The method, which makes use of the self-similarity property, is developed for the nonlinear flow equations. The method has proved to be an efficient and versatile procedure for constructing the numerical solutions to conical flow problems. It has been successful in computing the flow about circular and elliptic cones at conditions where small regions of supersonic cross flow develop and for the conical delta wings where the region of supersonic cross flow is extensive. The calculations made for circular and elliptic cones as well as for the compression side of various conical delta wings are in good agreement with experiment except in regions where viscous effects become important.

Download or read book Semiempirical Methods of Electronic Structure Calculation written by Gerald Segal and published by Springer. This book was released on 1977-04-01 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: If one reflects upon the range of chemical problems accessible to the current quantum theoretical methods for calculations on the electronic structure of molecules, one is immediately struck by the rather narrow limits imposed by economic and numerical feasibility. Most of the systems with which experimental photochemists actually work are beyond the grasp of ab initio methods due to the presence of a few reasonably large aromatic ring systems. Potential energy surfaces for all but the smallest molecules are extremely expensive to produce, even over a restricted group of the possible degrees of freedom, and molecules containing the higher elements of the periodic table remain virtually untouched due to the large numbers of electrons involved. Almost the entire class of molecules of real biological interest is simply out of the question. In general, the theoretician is reduced to model systems of variable appositeness in most of these fields. The fundamental problem, from a basic computational point of view, is that large molecules require large numbers of basis functions, whether Slater type orbitals or Gaussian functions suitably contracted, to provide even a modestly accurate description of the molecular electronic environment. This leads to the necessity of dealing with very large matrices and numbers of integrals within the Hartree-Fock approximation and quickly becomes both numerically difficult and uneconomic.
