Abstract
Ce rapport presente une etude de l'exactitude de modeles geometriques utilises avec divers types de scanners. Plus de 100 sections provenant de cinq tiges ont ete digitalisees ("scannees") sous 36 angles equidistants qui couvraient le cercle. Ces images digitalisees ont servi a simuler les lectures prises par les scanners infrarouge (rideau de lumiere) ou camera de 1 axe, 2 axes, 3 axes et 4 axes. Un test que consistait a superposer l'image de la section a l'image du modele geometrique a permis de calculer l'aire de la section qui etait bien representee par le modele, l'aire de la section qui etait perdue et l'aire de la section qui etait ajoutee par le modele. Les 36 positions des diverses sections ont permis de tester la sensibilite des modeles a l'orientation de la section. Le regroupement des valeurs d'aire calculee a permis de determiner la sensibilite des modeles a la position de la section sur la tige et de comparer les modeles selon le type d'utilisation que l'on en fait. Ce rapport presente aussi les bases theoriques (equations) des divers modeles.
Les conclusions sont que pour le classement des billes selon le diametre, un modele pour scanner un axe est suffisant. Cependant, il a ete demontre qu'un modele 1 axe couramment utilise dans l'industrie de l'est du Canada n'est pas satisfaisant pour la mesure des volumes. Le modele ideal pour le cubage est un modele lie aux scanners a deux axes. Enfin, le modeles que nous recommandons pour le positionnement en vue de l'automatisation ou de l'optimisation du premier debitage est un modele lie aux scanners a trois axes. Le peu de difference entre les modeles pour scanner a trois axes et quatre axes ne justifie pas l'emploi de ces derniers. Pour combler un besoin plus grand d'exactitude, nous recommandons l'utilisation d'une autre technologie que les scanners infrarouge ou camera.

Abstract
Computer modelling is an essential part in the analysis and design of mid- and high-rise residential and commercial buildings as well as long-span structures. It is also a valuable tool in the optimisation of wood-based products, connections, and systems. An FPInnovations’ survey shows that practicing engineers are unfamiliar with timber structure modelling, and researchers generally lack resources for advanced modelling of timber systems. Furthermore, wood analysis and design modules currently implemented in a few structural analysis software are usually not suitable for complex or hybrid timber structures. This does not bode well given that performance-based design which is the future direction of building codes and material standards will rely even more on demonstrating the structural performance through computer modelling. In this project, a modelling guide for timber structures is being developed by FPInnovations with a global collaborative effort involving experts in various areas, with the aim of (a) assisting practicing engineers apply computer modelling to timber structures; (b) enriching researchers’ resources for advanced computer modelling of timber systems; and (c) assisting software companies to identify the gaps and upgrade their programs accordingly to accommodate advanced computer modelling of timber structures.

Abstract
La construction massive en bois est relativement nouvelle et sera bientôt intégrée dans le Code national du bâtiment du Canada (CNB). Il s'agit d'une solution à base de bois à prix compétitif qui complète les systèmes existants à ossature en bois et de construction en gros bois d’œuvre et constitue une option appropriée pour certaines applications qui utilisent actuellement du béton, de la maçonnerie ou de l'acier.

Abstract
Mass timber construction is a relatively new type of construction soon to be implemented in the National Building Code of Canada (NBCC). It is a cost-competitive wood-based solution that complements existing wood-frame and heavy timber systems and is a suitable candidate for some applications which currently use concrete, masonry and/or steel.

Abstract
Stream networks shown on public maps are often incomplete and their accuracy fails to meet the full needs of forest managers. Stream Network Extraction (SNE) from a LiDAR Digital Elevation Model (DEM) has the potential to add to the already mapped streams and provide more hydrographical information. This report describes the potential of two different SNE programs with a LiDAR-derived DEM.

Abstract
FPInnovations has developed a simulation based decision support tool to help log and sort yard managers quickly evaluate and quantify the impact of changes in the yard operation in a virtual framework. Some examples of changes that could be evaluated by the model include changes in the infrastructure, yard layout, machine combination, and yard throughput. The tool was tested and validated in a coastal log and sort yard, and is customizable to log and sort yards with similar operation. In this report, the model, its capabilities, and results from the test site are presented.
