В книге описаны новые направления теории автомобиля, обусловленные созданием достаточно точных математических моделей отдельных звеньев системы "дорога-шина-автомобиль-водитель" и изучением динамики этой системы как единого целого при случайных воздействиях дорожных поверхностей. Исследованы основные эксплуатационные свойства автомобиля: плавность хода, устойчивость и управляемость движения при помощи современных методов теории случайных процессов и теории автоматического управления.

System protection is laid between the defenses for power system protective relaying and the emergency control. Under the premise of ensuring the safety of electrical equipment, it strives to ensure the safety of the system, block the chain of occurrence and growth of cascading faults, and effectively avoid the occurrence of large-scale blackout catastrophes. This book systematically elaborates on the dealing technology of a special type of fault, the “cascading fault”, in the AC-DC hybrid large-scale power grid. The main contents include immunization distance protection for accident overload; distance protection that is immune to oscillation; inverter control technology to prevent long-term or continuous commutation failure; DC participation emergency power flow control technology used to share the accident transfer overload caused by inverter lockout; and overhead transmission line adaptive overload protection.

This book presents a concise and focused introduction to engineering statistics, emphasizing topics and concepts that a practicing engineer is mostly likely to use: the display of data, confidence intervals, hypothesis testing, fitting straight lines to data, and designing experiments to find the impact of process changes on a system or its output. It introduces the language of statistics, derives equations with sufficient detail so that there is no mystery as to how they came about, makes extensive use of tables to collect and summarize important formulas and concepts, and utilizes enhanced graphics that are packed with visual information to illustrate the meaning of the equations and their usage. The book can be used as an introduction to the subject, to refresh one’s knowledge of engineering statistics, to complement course materials, as a study guide, and to provide a resource in laboratories where data acquisition and analysis are performed. The book recognizes that there are many computational tools available to perform the statistical analysis of data, and, therefore, the numerical details in the more computationally intensive examples are omitted. However, to facilitate all numerical calculations used in the book and to permit one to further explore the material, a set of interactive graphics (IGs) has been created using Mathematica.

Underwater robots play a significant role in ocean exploration. This book provides full coverage of the theoretical and practical aspects of bionic gliding underwater robots, including system design, modeling control, and motion planning. To overcome the inherent shortcomings of traditional underwater robots that can simultaneously lack maneuverability and endurance, a new type of robot, the bionic gliding underwater robot, has attracted much attention from scientists and engineers. On the one hand, by imitating the appearance and swimming mechanisms of natural creatures, bionic gliding underwater robots achieve high maneuverability, swimming efficiency, and strong concealment. On the other hand, borrowing from the buoyancy adjustment systems of underwater gliders, bionic gliding underwater robots can obtain strong endurance, which is significant in practical applications. Taking gliding robotic dolphin and fish as examples, the designed prototypes and proposed methods are discussed, offering valuable insights into the development of next-generation underwater robots that are well suited for various oceanic applications.

Finally, an easy explanation of Crackle Weave! Susan Kesler-Simpson, author of the popular Overshot Simply and Shadow Weave Simply, now explains Crackle Weave "simply." Her teaching style is to break down the weave structure into its basic parts so that it is easy to understand, and then teach you how the parts work together to create the weave structure so that you can use any pattern or create your own. The areas of separating threads give Crackle Weave its appearance of cracking pottery, and once you see how the structure works, there is so much you can do with it!

В учебнике изложены вопросы курса строительной механики (статика и динамика сооружений). Материал иллюстрируется конкретными примерами. Рассматриваются методы расчета с использованием ПК, указываются особенности этих методов. В книге отражено современное состояние строительной механики. Строительная механика является основополагающей наукой в образовании инженера. В строительной механике изучаются не сооружения, а их модели — расчетные схемы. Первоначально в строительной механики рассматриваются в основном стержневые системы. В большинстве задач предполагается, что стержни испытывают малые деформации, подчиняясь закону Гука (прямая пропорциональность между силами действующими в стержне и его деформациями).

The book presents a unique view of failure analysis of high technology devices. It describes capabilities and limitations of many analytical techniques and testing paths and decisions best followed in example failure analysis studies. In this book, we will attempt to cover only the corner of the FA world considering high tech devices and materials. So, we will leave out buildings, bridges, dams, and other large objects, as well as the mysterious area of software. The failure investigation investigating why a system fails (a phone, television, smart watch, or any other device made up of several components) is different than the FA of a single part (resistor, chip, tube), although these are in turn made up of smaller parts themselves. No matter the subject of an investigation, the goal of FA remains unchanged. To find out what caused the failure: the root cause. Even finding the root cause is rarely the end purpose.

Low-dimensional magnetic materials find their wide applications in many areas, including spintronics, memory devices, catalysis, biomedical, sensors, electromagnetic shielding, aerospace, and energy. This book provides a comprehensive discussion on magnetic nanomaterials for emerging applications. Fundamentals along with applications of low-dimensional magnetic materials in spintronics, catalysis, memory, biomedicals, toxic waste removal, aerospace, telecommunications, batteries, supercapacitors, flexible electronics, and many more are covered in detail to provide a full spectrum of their advanced applications. The scaling of Complementary Metal Oxide Semiconductor (CMOS) technology leads to an increase in leakage current and static power dissipation in memories and logic-based circuits. This limits the miniaturization of CMOS-based electronic devices. So, there is a need to replace these conventional charge-based electronic devices with some novel technologies. Spintronics is an emerging feld that has the potential to replace mainstream electronics.
