Product lifecycle management (PLM) systems formally represent product information across the different functional departments of an organization throughout an entire product lifecycle. Integrating the PLM systems with the emerging semantic web will improve the knowledge management capabilities of these systems. In recent works, the authors have developed the e-Design framework, a collaborative ...

RÉSUMÉ. Les phases amont des projets de conception peuvent être des périodes propices à l’introduction d’innovations technologiques dans les produits. Lors de ces phases, les processus de coopération et de confrontation des différents points de vue entre les acteurs impliquent des échanges d’informations qui sont parfois informels, non contractuels et peu ou pas structurés. Pourtant, ces phases...

Product Data Management (PDM) desktop and web based systems maintain the organizational technical and managerial data to increase the quality of products by improving the processes of development, business process flows, change management, product structure management, project tracking and resource planning. Though PDM is heavily benefiting industry but PDM community is facing a very serious un...

Recent regulatory requirements for shipping emissions control have led to the adoption of Liquefied Natural Gas (LNG) as a marine fuel and design LNG-fuelled vessels. Considering potential safety implications due system failure/unavailability, this study aims at analysis low-pressure LNG feeding using novel model-based methodology. The proposed methodology is based on functional modelling, lead...

The introduction of winter canola (Brassica napus L.) into rotations with wheat (Triticum aestivum in the United States (US) revealed economic and agronomic benefits as well improved weed pest control. Canola stand establishment during fall plant survival over are critical to success this crop. environment plays a key role influencing survival, but in-depth evaluation meteorological factors has...

This project brings together ve distributed university-based participants, each contributing unique models and architectures of client/server implementations that support one or more design phases in a distributed collaborative environment.ticated data packing mechanism for passing complex objects between the client/server with minimum programming eeort. NCSU: Collaborative user-conngurable wor...

Numerous models and indices exist that attempt to characterize the effect of environmental factors on the comfort of animals and humans. Heat and cold indices have been utilized to adjust ambient temperature (Ta) for the effects of relative humidity (RH) or wind speed (WS) or both for the purposes of obtaining a "feels-like" or apparent temperature. However, no model has been found that incorpo...

This Lessons from History article about the wind-chill index (WCI) explores historical polar and meteorologic literature relevant to topic presents unpublished work 1939. Geographer Paul Siple (1908–1968) was a 6-time Antarctic explorer scientist who invented named WCI in his doctoral dissertation at Clark University. Charles Passel (1915–2002) performed studies Antarctica 1940 that led publica...
