Abstract:
AbstractA review of work reported in the literature was used to present quantitative descriptions of energy dispositioning in the growing pig. These are detailed in the text, which points to preferred values, as well as to anomalies and lacunae. The review was prepared with the objective of allowing from its content the inclusive and quantitative modelling of energy requirement. Requirement is approached as the sum of the component factors; maintenance, protein retention and lipid retention. Conventional expressions of maintenance requirement, as some function of pig mass, were found unconvinc

Abstract:
Due to the complexity and variability of unsaturated soil, the permeability property of unsaturated soils is clearly different from that of saturated soil. And because the test equipment is more complex and technical requirements are higher and diachronic cycle is longer, the researches related are slow. Using the triaxial apparatus of unsaturated soil, the direct and indirect experiments to study the permeability coefficient of unsaturated silty clay are done. Test results show that the permeability coefficient of unsaturated soil can be done by the indirect method and direct method. Not only

Abstract:
In the last three decades, core design and operational requirements of German PWRs have evolved significantly in order to optimize plant operation and to react to changed market conditions. In the first phase, steady state operation was optimized to limit plant operation costs or increase availability and power output. The second phase of the evolution was triggered by the necessity of flexible plant operation in order to compensate fluctuating power generation by wind and solar power and by optimization of phase out cores. The changes of core design and operation parameters had among the dire

Milking is one of the essential technological processes when the direct contact of the cow living organism with the machine takes place. Failure to comply with the requirements of favourable interaction between these two different systems leads to cow diseases, lower productivity and milk quality, and, consequently, poorer production efficiency. The purpose of the study was to develop a method for the diagnostics of milking systems using digital technologies, which would allow the real-time detecting of operational disturbances of milking machines, their units and blocks.

We built the input-output tables employing the methodology developed by Guilhoto and Sesso (2005).

Abstract:
The technological evolution of networks together with the development of positioning systems has contributed to the emergence of numerous location-based services. Services related to this expanding area will become of major technical as well as economical interest in the coming few years. This aroused a great deal of interest from the scientific community at large and specifically from those studying these services and their diverse requirements and constraints. One of the direct consequences in the database field is the appearance of new types of queries (mobile queries issued from mobile terminals and/or requesting information associated with moving objects such as vehicles). Our objective in this chapter is to present a comprehensive survey of the field of research work related to mobile queries, with particular attention to the location issue.

Abstract:
Recent technological advancements in virtual environment equipment have led to the development of augmented reality displays for applications in medicine, manufacturing, and scientific visualization (Bajura et al., 1992; Janin et al., 1993; Milgram et al., 1991; Lion et al., 1993). However, even with technological advances in virtual environment equipment, the development of augmented reality displays are still in the early stages of development, primarily demonstrating the possibilities, the use, and the technical realization of the concept. The purpose of this chapter is to review the literature on the design and use of augmented reality displays, to suggest applications for this technology, and to suggest new techniques to create these displays. In addition, the chapter also discusses the technological issues associated with creating augmented realities such as image registration, update rate, and the range and sensitivity of position sensors. Furthermore, the chapter discusses humanfactors issues and visual requirements that should be considered when creating augmented-reality displays. Essentially, an augmented-reality display allows a designer to combine part or all of a real-world visual scene, with synthetic imagery. Typically, the real-world visual scene in an augmented-reality display is captured by video or directly viewed. In terms of descriptions of augmented reality found in the literature, Janin et al. (1993) used the term “augmented reality” to signify a see-through head-mounted display (HMD) which allowed the user to view his surroundings with the addition of computer graphics overlaid on the real-world scene. Similarly, Robinett (1992) suggested the term “augmented reality” for a real image that was being enhanced with synthetic parts; he called the result a “merged representation”. Finally, Fuchs and Neuman (1993) observed that an augmented-reality display combined a simulated environment with direct perception of the world with the capability to interactively manipulate the real or virtual object(s). Based on the above descriptions, most current augmented-reality displays are designed using see-through HMDs which allow the observer to view the real world directly with the naked eye. However, if video is used to capture the real world, one may use either an opaque HMD or a screen-based system to view the scene (Lion et al., 1993).
