摘要:Accurate vehicle localization in forest environments is still an unresolved problem. Global navigation satellite systems (GNSS) have well known limitations in dense forest, and have to be combined with for instance laser based SLAM algorithms to provide satisfying accuracy. Such ...

摘要:Abstract(#br)Performance of harvesting operations is vital for wood supply chains to enable delivery of the right product to the right market at the right price. Consequently, the performance of harvesting contractors has been the topic of many studies over the years, but fe...

摘要:ABSTRACT(#br)Size and spatial distribution of trees are important for forest stand growth, but the extent to which it matters in thinning operations, in terms of wood production and stand economy, has rarely been documented. Here we investigate how the choice of spatial evenness ...

摘要:ABSTRACT(#br)Competition for woody biomass between material and energy uses is expected to further increase in the future, due to the limited availability of forest resources and increasing demand of wood for material and bioenergy. Currently, methodological approaches for m...

摘要:Exposure to whole body vibration (WBV) is a major concern in mechanized forestry work because its adverse effects may become exacerbated by repetitive hand and arm movements, and nonneutral body postures. Moreover, shock-type vibrations have recently been suggested as a possible ...

摘要:Abstract(#br)Wheel slip may increase the risk for wheel rutting and tear up ground vegetation and superficial roots and thereby decreasing the bearing capacity of the ground, but also reducing the growth of nearby standing forest trees. With increased slip, more energy is co...

摘要:STUDY DESIGN.: Human volunteers were exposed experimentally to single-sided mechanical shocks (SSMS) and double-sided mechanical shocks (DSMS) while seated. OBJECTIVE.: To describe and contrast seated postural reactions due to SSMS or DSMS in healthy male adults. SUMMARY OF ...

摘要:In mechanized ground-based forestry, machines operate on rough soils that, ideally, should remain unaffected by the operation. This implies small (that is, light) loads and careful driving are required. However, economical rationality implies large loads and high speeds. Recently...

摘要:Modern harvesters are technologically sophisticated, with many useful features such as the ability to automatically measure stem diameters and lengths. This information is processed in real time to support value optimization when cutting stems into logs. It can also be transferre...
