ISBN: 978-1-119-49039-5
From a collaborative effort of the Center for Chemical Process Safety (CCPS) and the Energy Institute (EI) comes an invaluable book that puts the focus on a specific qualitative risk management methodology – bow tie barrier analysis. The book contains practical advice for conducting an effective bow tie analysis and offers guidance for creating bow tie diagrams for process safety and risk management. Bow Ties in Risk Management clearly shows how bow tie analysis and diagrams fit into an overall process safety and risk management framework.
Implementing the methods outlined in this book will improve the quality of bow tie analysis and bow tie diagrams across an organization and the industry. This important guide:
- Explains the proven concept of bow tie barrier analysis for the preventing and mitigation of incident pathways, especially related to major accidents.
- Shows how to avoid common pitfalls and is filled with real-world examples.
- Explains the practical application of the bow tie method throughout an organization.
- Reveals how to treat human and organizational factors in a sound and practical manner.
- Includes additional material available online.
Although this book is written primarily for anyone involved with or responsible for managing process safety risks, this book is applicable to anyone using bow tie risk management practices in other safety and environmental or Enterprise Risk Management applications. It is designed for a wide audience, from beginners with little to no background in barrier management, to experienced professionals who may already be familiar with bow ties, their elements, the methodology, and their relation to risk management.
The missions of both the CCPS and EI include developing and disseminating knowledge, skills, and good practices to protect people, property and the environment by bringing the best knowledge and practices to industry, academia, governments and the public around the world through collective wisdom, tools, training and expertise. The CCPS has been at the forefront of documenting and sharing important process safety risk assessment methodologies for more than 30 years. The EI's Technical Work Program addresses the depth and breadth of the energy sector, from fuels and fuels distribution to health and safety, sustainability and the environment. The EI program provides cost-effective, value-adding knowledge on key current and future international issues affecting those in the energy sector. |

TRL TRANSYT v16.0.0.8411
TRANSYT is a software suite containing a macroscopic traffic model, a signal optimiser, and a simulation model for the purpose of designing, evaluating and modelling everything from single isolated road junctions to large mixed signal-controlled and priority control traffic networks.
Signal timings at road junctions have an important effect on levels of traffic congestion, both at the junction itself and at surrounding junctions which may be signalised or priority-controlled. Ensuring traffic signals are timed effectively is one of the most cost-effective methods for reducing congestion.
Based on decades of research and development, TRANSYT is a now a comprehensive global product used for optimising traffic signals at single junctions and large traffic networks of mixed control. It is designed specifically to give quick solutions with minimal user input, and also more considered solutions when needed.
TRANSYT modelling can feed into many processes – Its signal plans used for fixed time signals; cableless linking facilities; SCOOT base timings; vehicle actuation maximum timings and also used to predict the performance of the aforementioned.
Furthermore, through the addition of a simulation model, TRANSYT’s capability is extended to include the modelling of non-cyclic signalling scenarios.
TRANSYT is used across the globe by traffic engineers, traffic modellers, junction designers, students and tutors, working for local authorities; municipal, state and regional authorities; consultancies of all sizes from multi-nationals to the smallest businesses; universities; other educational establishments.
TRANSYT can model mixed networks of signalised and unsignalised junctions. Furthermore, when used in conjunction with a Junctions licence, it has the capability to predict the performance of priority junctions using standard ARCADY PICADY geometric data. |

Mario Paz, Young Hoon Kim - Structural Dynamics, Theory and Computation, Sixth Edition
Springer, 2019
pdf, 629 pages, english
ISBN: 978-3-319-94742-6
The sixth edition of Structural Dynamics: Theory and Computation is the complete and comprehensive text in the field. It presents modern methods of analysis and techniques adaptable to computer programming clearly and easily. The book is ideal as a text for advanced undergraduates or graduate students taking a first course in structural dynamics. It is arranged in such a way that it can be used for a one- or two-semester course, or span the undergraduate and graduate levels. In addition, this text will serve the practicing engineer as a primary reference.
The text differs from the standard approach of other presentations in which topics are ordered by their mathematical complexity. This text is organized by the type of structural modeling. The author simplifies the subject by presenting a single degree-of-freedom system in the first chapters, then moves to systems with many degrees-of-freedom in the following chapters. Finally, the text moves to applications of the first chapters and special topics in structural dynamics.
This revised textbook intends to provide enhanced learning materials for students to learn structural dynamics, ranging from basics to advanced topics, including their application. When a line-by-line programming language is included with solved problems, students can learn course materials easily and visualize the solved problems using a program. Among several programming languages, MATLAB® has been adopted by many academic institutions across several disciplines. Many educators and students in the U.S. and many international institutions can readily access MATLAB, which has an appropriate programming language to solve and simulate problems in the textbook. It effectively allows matrix manipulations and plotting of data. Therefore, multi-degree-of freedom problems can be solved in conjunction with the finite element method using MATLAB. |

Marshall Day Acoustics INSUL v9.0.22
INSUL is a program for predicting the sound insulation of walls, floors, roofs, ceilings and windows. Impact sound and rain noise of floors and roof. The programme can make good estimates of the Transmission Loss (TL) or Impact Sound (Ln) in 1/3 octave bands and Weighted Sound Reduction Index (STC or Rw) or Impact Rating (IIC/LnTw) for use in noise transfer calculations or acoustical design or specification.
INSUL can be used to quickly evaluate new materials and systems, or to investigate the effects of changes to existing designs. It models materials using well known elastic plate theory including allowances for thick panel effects as published by Ljunggren, Rindell and others. More complex partitions are modelled using work by Sharp, Cremer and others.
INSUL has been available for over 15 years, and has undergone considerable improvements over this time. It has evolved over many releases and into a very easy to use tool that takes advantage of the Windows and Mac environments, and has been refined by continued comparison with laboratory tests to provide acceptable accuracy for a wide range of constructions. Test data can be entered for easy comparison with predictions and constructions can be saved for later recall. INSUL takes account of finite size effects which are very important when predicting small samples such as windows and also for normal elements at low frequencies. Like any prediction tool INSUL is not a substitute for measurement. However, comparisons with test data indicate that INSUL reliably predicts STC values to within 3dB for most constructions. INSUL will greatly enhance the ability of acoustic consultants and product manufacturers to quickly and confidently specify constructions in order to achieve a desired airborne sound insulation.

B. S. Grewal - Numerical Methods in Engineering and Science: C, C++, and MATLAB
Mercury Learning and Information, 2019
pdf, 951 pages, english
ISBN: 978-1-68392-128-8
This book is intended as an introduction to numerical methods for scientists and engineers. Providing an excellent balance of theoretical and applied topics, it shows the numerical methods used with C, C++, and MATLAB.
The limitations of analytical methods in practical applications have led scientists and engineers to evolve numerical methods. We know that exact methods often fail in drawing plausible inferences from a given set of tabulated data or in finding roots of transcendental equations or in solving non-linear differential equations. There are many more such situations where analytical methods are unable to produce desirable results. Even if analytical solutions are available, these are not amenable to direct numerical interpretation.
The aim of numerical analysis is therefore, to provide constructive methods for obtaining answers to such problems in a numerical form.
With the advent of high speed computers and increasing demand for numerical solution to various problems, numerical techniques have become indispensible tools in the hands of engineers and scientists.
The input information is rarely exact since it comes from some measurement or the other and the method also introduces further error. As such, the error in the final result may be due to an error in the initial data or in the method or both. Our effort will be to minimize these errors, so as to get the best possible results. We therefore begin by explaining various kinds of approximations and errors which may occur in a problem and derive some results on error propagation in numerical calculations. |
