This book addresses the problem of finding ampacities of underground cables. Although standard methods for solving this problem provide satisfactory results, however, these results are not always optimal and algorithms are not always convergent. This book takes these standard methods as a starting point and formulates the ampacity calculations as an optimization problem. The solution to this optimization problem gives the required ampacities, and is determined by utilizing the barrier method algorithm. This algorithm is implemented in FORTRAN-77 and used to obtain ampacity solutions for various cable configurations. The results are compared with ampacities obtained using standard methods, implemented in the CYMCAP commercial software...

The Amphion class (also known as the "A" class and Acheron class) of diesel-electric submarines were ordered by the British Admiralty in 1943, upon the realisation that the new Pacific theatre of war following the attack on Pearl Harbor needed a new type of submarine. They were originally designed to replace the S-class and T-class submarines, which were too slow and unable to dive deep enough to be suited to Pacific waters during World War II. They were an enlargement of the T class, arranged for fast, simple construction and to utilize much of the materials and equipment set aside for the T boats. They had a high, flared bow for excellent sea performance and had effective air conditioning, essential for Far East submarine operations....

The Amphitrite class monitors were a class of four U.S. Navy monitors ordered in the aftermath of the Virginius affair with Spain in 1873. A fifth ship originally of the same design, USS Puritan (BM-1), was later fitted with extra armor and designated as a unique class. Puritan and the Amphitrite class were to remain under construction for an extraordinarily long period due both to design changes and to the reluctance of the U.S. Congress to appropriate funds for their completion. Most of the vessels were only commissioned in the mid-1890s—more than twenty years after the commencement of construction. They were eventually to see active service in the Spanish-American War.

High occupancy vehicle (HOV) lanes are freeway lanes reserved for vehicles with more than a predetermined number of occupants. HOV lanes can affect the capacity of a freeway through both an underutilization effect and a disruption effect caused by lane-changes. This book examines the physics of HOV lanes and their overall impact on traffic. It uses a simple car-following model with lane-changing that matches field data with considerable accuracy. Current models of this type have usually a large number of parameters, many of them unobservable and/or with no physical meaning. This one, in contrast, requires few parameters and is based only on physical principles. It uses simple microscopic rules to reproduce the aggregate characteristics...

The integration of large systems remains problematic in spite of advances in composite services approaches. Current composite services approaches can effectively address only the integration of mechanistic processes. Processes with human interaction, abundant in large systems, are integrated in an ad hoc manner. As a result, a process gap occurs between user needs and implemented systems. The lack of support for human interaction with processes in large systems is referred to as the composite process-personalization (CPP) challenge. An architecture framework is presented that can systematically address the lack of CPP in current composite services approach. The framework is validated with two case studies, one in the biomedical...

Steady Hand cooperative manipulation is a hands-on approach that integrates seamlessly in the surgical practice. In steady hand manipulation, the tool is held simultaneously by the user and the robot and the robot complies to forces applied by the user. Steady hand manipulation promises significant improvements in safety, accuracy over conventional practice at minimal cost and training to the user. It also offers a way around the difficult problem of encoding human intelligence, and preserves the benefits from experience and training. We explore the possibility of encoding/utilizing task descriptions to improve transparency and performance of a steady hand manipulation task. This is done by constructing higher level representations of...

In the field of sustainable manufacturing, a wide range of research has been carried out to attain the more effective use of natural resources and the reduction of environmental impacts. This goal can be best achieved by promoting multiple-reuse of parts, sub-assemblies, or entire products. However, the decision toward reusing an old product depends on a variety of parameters with many uncertainties. This book, therefore, provides a comprehensive assessment model, integrating technical, environmental, social, and economic aspects to evaluate the reusability of industrial products. The model integrates uncertainties into the assessment and also facilitates trade-offs between the factors to investigate the possibility to improve the...

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. An analog-to-digital converter (abbreviated ADC, A/D or A to D) is a device which converts continuous signals to discrete digital numbers. The reverse operation is performed by a digital-to-analog converter (DAC). Typically, an ADC is an electronic device that converts an input analog voltage (or current) to a digital number proportional to the magnitude of the voltage or current. However, some non-electronic or only partially electronic devices, such as rotary encoders, can also be considered ADCs. The digital output may use different coding schemes, such as binary, Gray code or two's complement binary....

Not long afterwards John Logie Baird, Philo T.

Analog filters are vital building blocks in many modern electronic systems; their integration on-chip reduces size and cost due to the absence or limited use of external components. However, since lossless inductors cannot be integrated efficiently, it is necessary to emulate them using active circuitry. This issue adds many challenges to filter design because the use of active circuitry introduces noise and non-linearity to the system. Considerable attention to these undesirable properties is required, especially in the area of communications where high frequency signals with large dynamic range under low power constraints are critical. In this book, several design techniques are proposed and analyzed to obtain high frequency operation,...

Analytical mechanics is a term used for a refined, highly mathematical form of classical mechanics, constructed from the eighteenth century onwards as a formulation of the subject as founded by Isaac Newton. Often the term vectorial mechanics is applied to the form based on Newton's work, to contrast it with analytical mechanics. This distinction makes sense because analytical mechanics uses two scalar properties of motion, the kinetic and potential energies, instead of vector forces, to analyze the motion.
