Transient Airflow in Building Drainage Systems
by John SwaffieldGiving you the first comprehensive presentation of the ground breaking research undertaken at Heriot Watt University, with Research Council and industrial funding, this book brings a new perspective to the design of building drainage and vent systems. It provides the building services community with clear and verifiable design methods that will be robust enough to meet challenges such as climate change and water conservation; population migration to the mega cities of the developing world, and the consequent pressures of user concentration; the rise of the prestige building and the introduction of new appliances and control strategies. These all combine to make traditional codified design guidance insufficient. Many assumptions in existing codes defining the entrained airflows within building drainage vent systems cannot be theoretically supported, so designers concerned with these systems need analysis and simulation capabilities which are at least as reliable as those enjoyed by other building services practitioners. The Method of Characteristics solution techniques which are well established in the pressure surge field are now used to provide solutions for drainage designers. The material is applied to a whole range of abstract scenarios then to a series of real world applications including the forensic modelling of the SARS virus spread within Amoy Gardens in 2003 and the refurbishment of the O2 Dome. Applications to specialised services, including underground station drainage and highly infectious disease treatment facilities are discussed and demonstrated, alongside the use of design and simulation techniques in support of product development. Aimed at both professional and academic users, this book serves both as a design aid and as a core text for specialist masters courses in public health and building services engineering.

Transient Analysis of Power Systems
by Juan A. Martinez-VelascoThe simulation of electromagnetic transients is a mature field that plays an important role in the design of modern power systems. Since the first steps in this field to date, a significant effort has been dedicated to the development of new techniques and more powerful software tools. Sophisticated models, complex solution techniques and powerful simulation tools have been developed to perform studies that are of supreme importance in the design of modern power systems. The first developments of transients tools were mostly aimed at calculating over-voltages. Presently, these tools are applied to a myriad of studies (e.g. FACTS and Custom Power applications, protective relay performance, simulation of smart grids) for which detailed models and fast solution methods can be of paramount importance.This book provides a basic understanding of the main aspects to be considered when performing electromagnetic transients studies, detailing the main applications of present electromagnetic transients (EMT) tools, and discusses new developments for enhanced simulation capability.Key features: Provides up-to-date information on solution techniques and software capabilities for simulation of electromagnetic transients.Covers key aspects that can expand the capabilities of a transient software tool (e.g. interfacing techniques) or speed up transients simulation (e.g. dynamic model averaging).Applies EMT-type tools to a wide spectrum of studies that range from fast electromagnetic transients to slow electromechanical transients, including power electronic applications, distributed energy resources and protection systems.Illustrates the application of EMT tools to the analysis and simulation of smart grids.

Transient Control of Gasoline Engines
by Tielong Shen Jiangyan Zhang Xiaohong Jiao Mingxin Kang Junichi Kako Akira OhataCar electronics and digital processing technology have been used to improve the efficiency and performance of engines for decades, yet the main focus is still on static or pseudo-static mode, while the engines loaded in the road vehicles are not always operated at static mode. This book describes the behavior of engine dynamics operated at transient mode as a dynamical system, and uses advanced control theory to design a real-time control strategy that can be used to improve efficiency and emission performance.
Transient Dynamics of Concentrated Particulate Suspensions Under Shear (Springer Theses)
by Endao HanThis thesis demonstrates the first use of high-speed ultrasound imaging to non-invasively probe how the interior of a dense suspension responds to impact. Suspensions of small solid particles in a simple liquid can generate a rich set of dynamic phenomena that are of fundamental scientific interest because they do not conform to the typical behavior expected of either solids or liquids. Most remarkable is the highly counter-intuitive ability of concentrated suspensions to strongly thicken and even solidify when sheared or impacted. The understanding of the mechanism driving this solidification is, however, still limited, especially for the important transient stage while the response develops as a function of time. In this thesis, high-speed ultrasound imaging is introduced to track, for the first time, the transition from the flowing to the solidified state and directly observe the shock-like shear fronts that accompany this transition. A model is developed that agrees quantitatively with the experimental measurements. The combination of imaging techniques, experimental design, and modeling in this thesis represents a major breakthrough for the understanding of the dynamic response of dense suspensions, with important implications for a wide range of applications ranging from the handling of slurries to additive manufacturing.
Transient Effects in Friction
by Andreas GoedeckeTransient friction effects determine the behavior of a wide class of mechatronic systems. Classic examples are squealing brakes, stiction in robotic arms, or stick-slip in linear drives. To properly design and understand mechatronic systems of this type, good quantitative models of transient friction effects are of primary interest. The theory developed in this book approaches this problem bottom-up, by deriving the behavior of macroscopic friction surfaces from the microscopic surface physics. The model is based on two assumptions: First, rough surfaces are inherently fractal, exhibiting roughness on a wide range of scales. Second, transient friction effects are caused by creep enlargement of the real area of contact between two bodies. This work demonstrates the results of extensive Finite Element analyses of the creep behavior of surface asperities, and proposes a generalized multi-scale area iteration for calculating the time-dependent real contact between two bodies. The toolset is then demonstrated both for the reproduction of a variety of experimental results on transient friction as well as for system simulations of two example systems.
Transient Free Surface Flows in Building Drainage Systems
by John SwaffieldClimate change will present a series of challenges to engineers concerned with the provision of both building internal appliance drainage networks and rainwater systems within the building boundary, generally identified as the connection to the sewer network. Climate change is now recognised as presenting both water shortage and enhanced rainfall design scenarios.In response to predictions about immanent climate change Transient Free Surface Flows in Building Drainage Systems addresses problems such as the reduction in water available to remove waste from buildings, and conversely, the increase in frequency of tropical-type torrential rain. Starting with introductory chapters that explain the theories and principles of solid transport, free surface flows within drainage networks, and attenuating appliance discharge flows, this book allows readers from a variety of backgrounds to fully engage with this crucial subject matter. Later chapters apply these theories to the design of sanitary and rainwater systems. Case studies highlight the applicability of the method in assessing the appropriateness of design approaches.In this unique book, research in modelling for free surface flows at Edinburgh’s Heriot-Watt University is drawn on to provide a highly authoritative, physics-based study of this complex engineering issue.

Transient Workspaces: Technologies of Everyday Innovation in Zimbabwe (The\mit Press Ser.)
by Clapperton Chakanets MavhungaAn account of technology in Africa from an African perspective, examining hunting in Zimbabwe as an example of an innovative mobile workspace.In this book, Clapperton Mavhunga views technology in Africa from an African perspective. Technology in his account is not something always brought in from outside, but is also something that ordinary people understand, make, and practice through their everyday innovations or creativities—including things that few would even consider technological. Technology does not always originate in the laboratory in a Western-style building but also in the society in the forest, in the crop field, and in other places where knowledge is made and turned into practical outcomes.African creativities are found in African mobilities. Mavhunga shows the movement of people as not merely conveyances across space but transient workspaces. Taking indigenous hunting in Zimbabwe as one example, he explores African philosophies of mobilities as spiritually guided and of the forest as a sacred space. Viewing the hunt as guided mobility, Mavhunga considers interesting questions of what constitutes technology under regimes of spirituality. He describes how African hunters extended their knowledge traditions to domesticate the gun, how European colonizers, with no remedy of their own, turned to indigenous hunters for help in combating the deadly tsetse fly, and examines how wildlife conservation regimes have criminalized African hunting rather than enlisting hunters (and their knowledge) as allies in wildlife sustainability. The hunt, Mavhunga writes, is one of many criminalized knowledges and practices to which African people turn in times of economic or political crisis. He argues that these practices need to be decriminalized and examined as technologies of everyday innovation with a view toward constructive engagement, innovating with Africans rather than for them.
Transients for Electrical Engineers: Elementary Switched-Circuit Analysis in the Time and Laplace Transform Domains (with a touch of MATLAB®)
by Paul J. NahinThis book offers a concise introduction to the analysis of electrical transients aimed at students who have completed introductory circuits and freshman calculus courses. While it is written under the assumption that these students are encountering transient electrical circuits for the first time, the mathematical and physical theory is not ‘watered-down.’ That is, the analysis of both lumped and continuous (transmission line) parameter circuits is performed with the use of differential equations (both ordinary and partial) in the time domain, and the Laplace transform. The transform is fully developed in the book for readers who are not assumed to have seen it before. The use of singular time functions (unit step and impulse) is addressed and illustrated through detailed examples.The appearance of paradoxical circuit situations, often ignored in many textbooks (because they are, perhaps, considered ‘difficult’ to explain) is fully embraced as an opportunity to challenge students. In addition, historical commentary is included throughout the book, to combat the misconception that the material in engineering textbooks was found engraved on Biblical stones, rather than painstakingly discovered by people of genius who often went down many wrong paths before finding the right one. MATLAB® is used throughout the book, with simple codes to quickly and easily generate transient response curves.
Transients of Modern Power Electronics

Transit-Oriented Development: Learning from International Case Studies
by Ren Thomas Luca BertoliniThis book uses international case studies to present insights on the policies, actors, and institutions that are critical to successful transit-oriented development (TOD). TOD has many potential benefits for cities and regions, and is considered a critical element in reshaping sprawling car-dependent urban regions into denser regions built around transit corridors. However, it is not a magic bullet solution for metropolitan transportation problems: challenges persist, such as displacement of local residents and regulatory barriers. How has TOD been successfully implemented? How can we integrate the positive aspects of TOD while minimizing its negative impacts? This book presents a study conducted at the University of Amsterdam, exploring 11 international case studies, including a meta-analysis, rough set analysis and policy transfer workshops. The authors discuss the findings and present solutions to persistent challenges to transit-oriented development. Additional literature on eTOD (equitable TOD) strategies, as a fundamental component of planning for regional transportation, shows that these approaches can result in more collaborative processes, community-led development that minimizes the negative impacts of transportation infrastructure. As our Dutch colleagues stated, TOD can be considered a policy concept that can be used as a story to unite people.

Teaching the Transition Engineering approach and methodology is the focus of the text, and the concept is presented in a way that engineers can begin applying it in their work.
The Transition Handbook
by Rob HopkinsWe live in an oil-dependent world, arriving at this level of dependency in a very short space of time by treating petroleum as if it were in infinite supply. Most of us avoid thinking about what happens when oil runs out (or becomes prohibitively expensive), but The Transition Handbook shows how the inevitable and profound changes ahead can have a positive outcome. These changes can lead to the rebirth of local communities that will grow more of their own food, generate their own power, and build their own houses using local materials. They can also encourage the development of local currencies to keep money in the local area. There are now over 30 "transition towns" in the UK, Australia and New Zealand with more joining as the idea takes off. They provide valuable experience and lessons-learned for those of us on this side of the Atlantic. With little proactive thinking at the governmental level, communities are taking matters into their own hands and acting locally. If your town is not a transition town, this upbeat guide offers you the tools for starting the process.

Transition-Metal Defects in Silicon
by Michael StegerThe fundamental properties of deep luminescence centres in Si associated with transition metals such as Cu, Ag, Au, and Pt have been a focus of interest for decades, both as markers for these deleterious contaminants, and also in the quest for efficient Si-based light emission. This dissertation presents the results of ultra-high resolution photoluminescence studies of these centres in specially prepared, highly enriched 28-Si samples. The greatly improved spectral resolution due to this enrichment led to the discovery of isotopic fingerprints. These fingerprints have revealed that the detailed constituents of all of the centres previously studied had been identified incorrectly. They also revealed the existence of several different families of impurity complexes containing either four or five atoms chosen from Li, Cu, Ag, Au, and Pt. These centres' constituents have been determined, together with no-phonon transition energies, no-phonon isotope shifts, local vibrational mode energies, and the isotope shifts of the local vibrational mode energies. The data presented here for these centres should prove useful for the currently sought theoretical explanations of their formation, stability, and properties.
