  • Energy is defined as the capacity of a substance to do work. It is a property of the substance and it can be transferred by interaction of a system and its surroundings. The student would have encountered these interactions during the study of Thermodynamics. However, Thermodynamics deals with the end states of the processes and provides no information on the physical mechanisms that caused the process to take place. Heat Transfer is an example of such a process. A convenient definition of heat transfer is energy in transition due to temperature differences.

  • This paper addresses a data-driven surface realisation model based on a large-scale reversible grammar of German. We investigate the relationship between the surface realisation performance and the character of the input to generation, i.e. its degree of underspecification. We extend a syntactic surface realisation system, which can be trained to choose among word order variants, such that the candidate set includes active and passive variants.

  • We present a discourse-level Tree Adjoining Grammar which tightly integrates syntax and discourse levels, including a representation for discourse entities. We show that this technique makes it possible to extend an optimisation algorithm used in natural language generation (polarity filtering) to the discourse level. We implemented the grammar in a surface realizer and show that this technique can be used to reduce the search space by filtering out referentially incoherent solutions.

  • The tension structures discussed in this book are predominantly roofing forms created from pre-stressed cable nets, cable trusses, and continuous membranes (fabric structures). A unique feature in their design is form-finding an interactive process of defining the shape of a structure under tension. The book discusses the role of stable minimal surfaces (minimum energy forms occurring in natural objects, such as soap films) in finding optimal shapes of membrane and cable structures.

  • My examples satisfy some aspects of this requirement, but not others. In each of the examples, there clearly are relations, however simple, between doing and undergoing. I undergo an experience, such as feeling that my hands are cold, and take action in response, warming my hands by caressing the sides of my mug. I adjust what I am doing in response to sensations that indicate the mug is too hot to grasp for any extended period; and I put the mug down once my sensations suggest that my hands have been sufficiently warmed. This...

  • Our knowledge of mass transfer processes has been extended and applied to various fields of science and engineering including industrial and manufacturing processes in recent years. Since mass transfer is a primordial phenomenon, it plays a key role in the scientific researches and fields of mechanical, energy, environmental, materials, bio, and chemical engineering. In this book, energetic authors provide present advances in scientific findings and technologies, and develop new theoretical models concerning mass transfer....

  • One of the core tenets of Scrum is that the duration of the Sprint is never extended – it ends on the assigned date regardless of whether the team has completed the work it committed to. If the team has not completed their Sprint Goal, they have to stand up at the end of the Sprint and acknowledge that they did not meet their commitment. The idea is that this creates a very visible feedback loop, and teams are forced to get better at estimating what they are capable of accomplishing in a given Sprint, and then delivering it more...

  • Computational fluid dynamics, usually abbreviated as CFD, is a branch of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the calculations required to simulate the interaction of liquids and gases with surfaces defined by boundary conditions. With high-speed supercomputers, better solutions can be achieved. Ongoing research yields software that improves the accuracy and speed of complex simulation scenarios such as transonic or turbulent flows.

  • Introduction: The modern interest for phenomena at the semiconductor–electrolyte interface dates back to experiments performed in the 1950s with germanium, and has extended to most semiconducting materials for reasons of fundamental knowledge or potential application, going from semiconductor processing technology to heterogeneous photocatalysis to sensors. The subject is highly interdisciplinary and involves fields like electrochemistry, solid-state physics, and surface science.

  • Improving the performance, extending the life, and enhancing the appearance of materials used for engineering components are fundamental--and increasingly important--concerns of ASM members. As the performance demands placed on materials in engineering applications have increased, the importance of surface engineering (cleaning, finishing, and coating) technologies have increased along with them.

  • This chapter presents basic knowledge on the special kind of the machining process in which a workpiece material hardened to 45–70 HRC hardness or more is machined with mixed ceramic or CBN tools. An extended comparison with finish grinding, as well with other abrasive finishing processes, is carried out. Specific cutting characteristics, including cutting forces, chip formation mechanisms and tool wear modes with relevant interface temperatures are discussed in terms of process conditions. Currently developing finite element (FE) and analytical modelling is overviewed.

  • The supraspinatus together create the rounded front edge of the shoulder form (located at the base of the side of the neck). In the ox, however, the supraspinatus alone creates the front of the shoulder form (the subclavius is deep). DOG AND FELINE • Origin: Outer surface of the front portion of the scapula and the adjacent cartilage. • Insertion: Inner and outer front corners of the top of the humerus. • Action: Extends the shoulder joint, advancing the limb. • Structure: The belly of the supraspinatus is thin where it begins, on the outside of the top of the shoulder blade;...

  • Many pavements, which are considered to be structurally sound after the construction of an overlay, prematurely exhibit a cracking pattern similar to that which existed in the underlying pavement. This propagation of an existing crack pattern, from discontinuities in the old pavement, into and through a new overlay is known as reflective cracking. Reflective cracks destroy surface continuity, decrease structural strength, and allow water to enter sublayers. Thus, the problems that weakened the old pavement are extended up into the new overlay.

  • Continental shelves are the gently sloping areas of the ocean floor, contiguous to the continent, that extend from the coastline to the shelf-break. The shelf break, which is located around 150–200 meters depth, is the area of the continental margin where there is an abrupt change between the shelf and the steeper continental slope. Primary production in the oceans, i.e. the production of organic compounds from dissolved carbon dioxide and nutrients through photosynthesis, is often associated with upwellings (Botsford et al., 2006).

  • On its surface, James Flaherty’s book looks to be a how-to text for a rapidly emerging set of disciplines and practices called Coaching. Don’t be misled. This book is a lot more than that, although you can read it for no other reason, and it will help you improve your practices as a coach (or as a coachee, a customer of coaching). Not long ago, coaching meant training athletes, performers, and students. Recently, the use of the term has been extended into the worlds of management, leadership, entrepreneurship, and performance in other domains of life....

  • This paper considers a trapped characteristic initial value problem for the spherically symmetric Einstein-Maxwell-scalar field equations. For an open set of initial data whose closure contains in particular Reissner-Nordstr¨m data, o the future boundary of the maximal domain of development is found to be a light-like surface along which the curvature blows up, and yet the metric can be continuously extended beyond it. This result is related to the strong cosmic censorship conjecture of Roger Penrose. ...
