作者： raquel V.Lourencon Amlan K.Patra Luana P.S.Ribeiro Ryszard Puchala Wei Wang Terry A.Gipson Arthur L.Goetsch American Institute for Goat Research Langston University

Thirty-two primiparous and 31 multiparous Alpine goats were used to determine influences of diets varying in level and source of forage on performance in early to mid-lactation for 16 wk. Diets consisted of 40%, 50%, 60%, and 70% forage(designated as 40F, 50F, 60F, and 70F, respectively) with 60F and 70F containing coarsely ground grass hay(primarily orchardgrass) and 40F and 50F containing cottonseed hulls, alfalfa pellets, and coarsely ground wheat hay. Diets contained 15.9% to 16.3% crude protein and37.8%, 42.1%, 53.5%, and 55.4% neutral detergent fiber(NDF) with 10.0%, 15.8%, 50.1%, and 55.5% particle retention on a 19-mm sieve, and 26.1%, 29.6%, 38.3%, and 40.0% physically effective NDF(pe NDF) for 40F,50F, 60F, and 70F, respectively. Dry matter intake(2.71, 2.75, 1.96, and 1.95 kg/d) and milk yield(2.82,2.71, 2.23, and 2.10 kg/d for 40F, 50F, 60F, and 70F, respectively) were lower(P 0.05), but digestibility of NDF was greater(P 0.05) by diet and was lower(P 0.05) by diet or parity, but many interactions involving diet, period, hour, and parity were significant(P < 0.05).

SYNCHRONOUS COMMUNICATION IN PLM ENVIRONMENTS USING ANNOTATED CAD MODELS

Journal of Systems Science and Systems Engineering 2016年第2期25卷 142-158页

作者： Jorge D. Camba Manuel Contero Gustavo Salvador-herranz raquel Plumed College of Architecture University of Houston Houston TX USA I3BH Universitat Politkenica de Valkncia Valencia Spain Depto. de Expresion Grafica Proyectos y Urbanismo Universidad CEU Cardenal Herrera Valencia Spain Depto. de Ingenierla Mecanica y Construccian Universitat Jaume I Castellon Spain

The connection of resources, data, and knowledge through communication technology plays a vital role in current collaborative design methodologies and Product Lifecycle Management （PLM） systems, as these elements act as channels for information and meaning. Despite significant advances in the area of PLM, most communication tools are used as separate services that are disconnected from existing development environments. Consequently, during a communication session, the specific elements being discussed are usually not linked to the context of the discussion, which may result in important information getting lost or becoming difficult to access. In this paper, we present a method to add synchronous communication functionality to a PLM system based on annotated information embedded in the CAD model. This approach provides users a communication channel that is built directly into the CAD interface and is valuable when individuals need to be contacted regarding the annotated aspects of a CAD model. We present the architecture of a new system and its integration with existing PLM systems, and describe the implementation details of an annotation-based video conferencing module for a commercial CAD application.
