This final thesis is performed on commission of Torsby forestry administration, Stora Enso Skog. Stora Enso Skog is one of the major forestry companies of Sweden. The main business area is located in and around the region of Bergslagen. During the last decade the practice of forest management has rapidly changed due to a new forest legislation. The new law has resulted in that the production goal is equal to the environmental goal within forestry.

The construction of buildings and paved surfaces changes the natural water balance.Precipitation generates surface runoff and storm water instead of infiltrating into the soil.Storm water has come to be considered as a major source of pollution in lakes and streams inthe vicinity of urban areas. Reduction of pollutants in storm water is a key action in order toprotect sensitive recipients and maintain high water quality. Storm water is traditionallytransported by storm sewers to the nearest recipient. In recent years the approach to stormwater management has changed; storm water should primarily be disposed of on site, throughlocal disposal of storm water, LOD. LOD is created by a combination of the function ofseveral smaller local facilities and the general sewer system.

Old hollow trees of oak contain a large amount of wood mould. Unfortunately, these trees have in the last century been greatly reduced in numbers. It has resulted in that species that depend on these habitats, saproxylic species, have become at risk to decrease in numbers or die out regionally. Previous studies have shown that the volume of wood mould is an important factor for occurrence and population size of saproxylic organisms. The aim of the present study was to examine how the volume of wood mould varies among ash (Fraxinus excelsior), lime (Tilia sp.), maple (Acer platanoides), aspen (Populus tremula) and oak (Quercus robur).

This study in the subject of forest planning is made for Sveaskog and its aim is to develop tools that prognosticate outcome in terms of volumes per sort from not yet cut forest stands. The degree of detail is just to get reliable results for at least one months volumes, for Sveaskogs own forestland in the market region of Norrbotten that is about 100 000 m3fub. The course of action to accomplish this is regression analysis and the data consists of cut tracts on own forestland in Norrbotten during the years 2006, 2007 and 2008. That is a little more than 4 million m3fub. Two tools were made.

The purpose of this paper is to describe and analyse the Chinese destination of Hainan, with background in a globalizing tourism destination development, for tourism from Finland and Sweden. The questions at issue are regarding what kind of an impact the status as a special economic zone have had upon Hainan, what kind of conditions there are for tourism on the island, in what form participants of the tourism industry want the development to proceed, what the prevailing trend is for distant destinations for Nordic markets and also regarding what kind of potential there is for organized tourism to Hainan from Finland and Sweden.As a foundation for the paper, I?ve composed a theoretical reference for knowledge of China, Hainan and the study of destinations. The sources of secondary kind are literature related to the subject. The primary sources are mainly interviews, field work done at Hainan has given a concrete and personal knowledge of the place.

Nature-like plantations are areas that, by today?s maintenance procedure usually gains low prioritiy and are forgotten. Most nature-like plantations are currently disadvantaged and have in many cases grown up and formed dense,impenetrable and brushwoody green volumes. These green volumes is rarely used, but usually only fills out gap surfaces. With proper care nature-like plantations can become health promoting environments in the increasinglyhardened urban environments.How vegetation systems work and how trees and shrubs interact is dependent on many factors.

With the advent of powerful multimedia capable mobile phones, the market for mobile services is flourishing. Zenterio AB's Halfpipe Active Desktop is a complete distributed mobile service platform a with a powerful server and platform-independent client. The communication between the client and server takes place over a GPRS-capable mobile network. The purpose of this thesis is to develop a secure communications protocol for use between the Halfpipe Active Desktop client and server. This is done by determining requirements, analyzing candidate protocols and then by designing the final protocol.

This report examines the prerequisites for LEDs to replace other technologies indifferent applications. How does the different technologies for light generationwork and what are the advantages and disadvantages? The various technologieslimitations and characteristics provides the opportunities for the LEDs.This report describes a test-construction built to examine what practical arrangementscan be built with modern light emitting diodes, in order to showsome of the possibilities. The construction consists of three different applications,a high power lamp based on cold white LEDs, one based on warm whiteLEDs for the evaluation of the light characteristics and a RGB-LED based lampable to mix any colors quickly and seamlessly. The test construction also containsthe essential peripherals including control-electronics, optics and a custombuilt watercooling solution.The potential for LEDs is huge but it is complicated to build LED based applicationsdue to the limitations which mainly includes the electronics and theneccesary cooling.

This thesis is made on behalf of SCA's Forestry Division and is a comparison of two bucking simulation tools: Aptan (manufactured by Skogforsk) and Best/upr (from Berget Systemdesign). The data is based on 32 stands from SCA's forests in Norrbotten and Västerbotten. The objective is to compare the simulations created by the tools with the harvested volumes from those stands. Three variables are needed for the bucking simulation; these are the diameter distribution (at breast height), the relationship function between diameter and height, and the taper coefficients. The volumes of five different assortments from the stands are compared.

This thesis compares the impact on disk performance in a GNU/Linux  environmentwith three encryption algorithms: AES,  Serpent and Twofish in three different implementations: DM-crypt, Loop-AES and Truecrypt. For all three algorithms a key length of 256 bits is used.The thesis shows that the least performance impact during data encryption, and thus file writing, is reached by using AES or Twofish encryption implemented in DM-crypt or TrueCrypt. The thesis shows that some data operations with a sufficiently low processor utilization barely affects disk performance at all if encrypted using the optimal implementation and algorithm.It is also discovered that the performance impact during data decryption, or file reading, can be minimized by using the most efficient implementation and algorithm. The best results are met with the AES or Twofish cipher, regardless of implementation.An important conclusion that  is  drawn is that it is hard to determine a superior encryption solution for all purposes. However, by reviewing and examining the collected data from all aspects of disk performance the AES implementation in TrueCrypt is, with small marginals, determined to be the most optimal..

AbstractThis bachelor?s thesis at the Department of Production Engineering at the Royal Institute of Technology in Stockholm deals with the subject of automated metrology. The degree of automation of tasks within production has been a growing trend but the measurement of quality has not followed the same trend. The main thesis follows:What incentives are there to automate the measurement of quality in production?What factors are crucial and why are not all metrology automated?The thesis comes along with a number of sub-queries and delimitations.The working method includes both theoretical and empirical studies.

The thesis treats how the German public libraries originated and how they were affected by the Nazi era. It deals with how the library system began to cover the whole nation, and describes the struggle between public libraries and commercial and religious ditto. It also treats the weedings out and what happened to the staff and the stocks between 1933 and 1945.Furthermore it gives a picture of what books one could find in a German public library,and how these volumes were catalogued and classified. Moreover it describes how thelibraries managed during the Second World War, and ends by giving some topics fordiscussion and asks questions that additional research might be able to answer..
