… year. According to the felling calculation from 2001 the share of standing volume broad-leaved trees should be at an average level of 18 %. Also according to this calculation the percentage by volume of broad-leaved trees in the thinning stands should be at a level of 21.4 % and …
… objectives for the work are that: ? Make a comparison between the measured volume in the standing forest and the measured volume at the industry on Uppsala Academy of Managements actual stumpage sale volume to see how well it conforms. ? Examine if the buyers see any particular …
As the volumes are entering the world of computer graphics the pure volume visualisation becomes a more important tool in for example research and medical applications. But the advance in haptics --- force feedback from the computer --- is behind. In volume haptics no equal to …
The aim of this study was to evaluate different types of volume and taper equations that can be used to predict single-tree stem volume and stem diameter at any given height along the tree stem for plantation grown Sitka spruce (Picea sitchensis (Bong.) Carr.), Norway spruce …
… The internal goal for Stora Enso Skog is to leave 5 percent of the wood volume of the productive forest at final cut operations for consideration for the nature. It has not been clear how much wood volume that’s really left in the forest. There has also been suspects that wood …
… of 10 Swedish half-blood stallions were determined (height, length, width and volume). Ejaculates were collected from each stallion once daily for 10 days to evaluate some important seminal characteristics: gel-free ejaculate volume, sperm concentration, percent progressively …
… this study were to describe the Sitka spruce growing characteristics and the volume production in comparison to spruce (Picea abies). The possibility to predict future volume production by using prognosis tools designed to be used on spruce were also studied. The material that …
… business since the demand for hardwood products has increased. The standing volume of deciduous trees in Sweden is today approximately 524 million m3sk and it has increased rapidly in recent years. However, the deciduous forests are to a large extent located in areas that are …
Utveckling av koncept för nivåmätning i lutande tankar
Today’s system to measure the volume in a tank consists of a vertically placed sensor. When a vehicle is tilted the level of the fluid might change and if the volume is calculated based only on the information from the sensor it could result in a incorrect value. This thesis …
en modellsimulering av planteringsförbandets inverkan?
… fraction of the annual growthring, 0,5 to 0,8 rings. To calculate heartwood volume modelings were carried out in four different pine stands with different spacings, 0,75, 1,25, 1,5 and three meters. The model indicates heartwood diameter (HWD) and is based on four explanatory …
To efficiently examine volumetric data sets from CT or MRI scans good volume rendering applications are needed. This thesis describes the design and implementation of an application programming interface (API) to be used when developing volume-rendering applications. A complete …
beskrivning av en gallringsmodell för granskog som tillämpas på Trolleholms Gods
… examine the thinning model that is carried out at the estate of Trolleholm. A volume table is calculated to describe the model, and data is collected on temporary plots. Analysis on effect of tinning operations is carried out, and analyses are made to confirm that the thinning …
… and Västerbotten. The stands were dominated by spruce and had rather high stem volume. A follow up on production data was done in five stands. In one of the stands a time study and a measure of stump biomass and moisture content was done. A Hyundai excavator (23.5 ton) with a …
… a practical point of view. The input used in this project is last year’s sales volumes and prices of sawn products. The input of the timber is collected from the database ”VIOL”. The results show that there is a great potential in optimising the sawing patterns compared to the …
… a number of type stands of lodge pole pine in Norrbotten with respect on stem volume and total biomass. Further questions to answer is if there is stand characteristics that make the stands more suitable for pulpwood in early thinning, or if it is better to apply whole tree …
