En undersökning av Bergvik skogs och Skogsstyrelsens gallringsmallar mot en gallringsoptimering på simulerade typbestånd

The purpose of this study was to analyze the two thinning models: Bergvik Skog´s thinning model, which is based on total stems and dominant height, And Swedish forest agency´s thinning model which is based on basal area, habitat index, dominant height and recommended number of stems at final felling in Heureka´s StandWise and PlanWise. The data we chosen for our study were taken from the Swedish National Forest Inventory and we were creating a simulated stand based on a great number of sample plots in Region three from The Swedish National Forest Inventory. We had chosen to create one stand with low habitat index (T20) and one with high habitat index (T24). Our purpose were to come as close as possible to a natural stand in central Sweden. We performed the thinning in StandWise and analyzed the data I Excel files. Our thinning optimizing´s were performed and analyzed in PlanWise. There wasn´t any big differences between the thinning on the lower habitat index.

Kan markfuktighetskartor användas för att hitta skogsmark med hög bonitet? : ett gis-baserat försök med dtw-index och laserskannad övre höjd

The depth-to-water-index (DTW-index) is derived from digital elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest site productivity (SP). The belief of such an assumed relationship was based on knowledge that the ground water level is related to site properties that can either promote or impede tree growth. Data primarily comprised rasters of the Krycklan catchment in northern Sweden and depicted DTW-index and a laser scanned vegetation height. The 100th height percentile of each pixel in the vegetation raster was assumed to mirror the top-height, letting it act as a relative measure of SP within a delineated area of equal stand age.

Kvinnor är inte ett ämne - Ämnesindexering på Kvinnohistoriska samlingarna

The purpose of this paper is to examine the subject indexing in the bibliographic databaseKVINNSAM at Kvinnohistoriska samlingarna. the documentation and information centre·of Women's studies in Sweden.The focus of the study is the list of index terms produced at this centre. The paper tries to answer the following questions: a) How has the indexing developed? b) How can it be improved? c) Is there a need for feminist indexing? The method of the study is primarily observations and interviews. Texts and ideas by Birger Hj¢rland, D.

Balanced Scorecard i svenska kommuner

Purpose: The purpose with our study is to accomplish a quantitative research of all municipalities in Sweden and see why they apply Balanced Scorecard. The study will also investigate the spread of Balanced Scorecard, even the benefits and how they use it. Method: In our study we have chosen a quantitative research. The study has been accomplished with a questionnaire survey which we sent to all of the Swedish municipalities. We have also done a literature study to get more knowledge about relevant theories.

Massundanträngning i samband med pålning i lera

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

Aktiv fondförvaltning på svenska marknaden : Svenska aktiefonders prestation i jämförelse mot passiv förvaltning i perioder av upp- och nedgång på Stockholmsbörsen mellan åren 1995-2010

I denna uppsats undersöks hur aktivt förvaltade svenska aktiefonder presterat i jämförelse mot passiv förvaltning i perioder av upp- och nedgång på Stockholmsbörsen mellan åren 1995-2010. I ett urval av 36 aktivt förvaltade Sverigefonder undersöks hur prestationerna står sig mot passiv förvaltning, om fondernas prestationer håller i sig över tid och om fondstorleken har betydelse för prestationen. Genom en uppdelning olik tidigare studier på fonders prestationer, där perioderna bestäms utefter marknadens upp- och nedgångscykler kan resultat tydligare framställas om aktivt förvaltade fonder presterar bättre än passiv förvaltning. Vi riskjusterar fondernas prestationer och jämför deras utveckling mot SIX Return Index och indexfonden Handelsbanken Mega Sverige Index (den passiva förvaltningen). Vi finner att aktiv förvaltning överlag inte lyckas genera högre avkastning än index i perioder av uppgångar men att de går bättre än index i nedgångar.

Bergerosion i utskovskanaler

Today?s climate changes will probably give rise to precipitation in Sweden, which will cause more floods in Swedish rivers. Many of the Swedish rivers are regulated and have lots of hydro-electro power plants. Higher floods in the rivers will give greater water loads on the dams, which mean that a higher discharge through the sluice gates and in the spillway channels is needed. High discharge of water in a spillway channel can create scour of the material in the channel.

Kan förändringar i bottenfaunan påvisas två år efter en bäckrestaurering?

The aim of this work is to analyze if a change in the benthic community can be detected two years after a restoration of a small stream. The samples were taken in a small stream at Tinnerö Eklandskap just south of Linköping. In addition to the restored area, two reference sites upstream and downstream of the restored area were sampled to compare to the restored site. The method used for sampling of benthic fauna in the stream was kick sampling. ASPT, Berger-Parker and Renkonen-indices were used to find out if there was any difference between the reference areas and the restored area.
