Kraftkabelförläggning i mark : - en studie av produktionsmetoder

The assignment given to us by NCC was to compose a degree project based on ground excavations for power cables. The aim of the study was to examine suitable excavation methods depending on different possible terrain conditions. The amount of previously written material within this subject is nearly non- existent and therefore there is a genuine interest by the NCC to receive a compilation of different production methods. The greater part of this study is based upon interviews with several companies active within this area of expertise. The technique of placing the electricity grid beneath ground for safety is today getting more and more common.

?Ett indiskret brott mot god takt och ton? : Om arkeologi och samtiden utifrån fångstmarksgravar

Hunting ground graves were distinguished as a separate category during the 1930s.         There is however no clear definition of what a hunting ground grave is. They have been constructed over a large area over a long period of time (200 BC-1200 AD) and their morphology varies.This paper investigates how the archaeologists have discussed the hunting ground graves since they were distinguished as a separate category until today. It investigates what concepts that have been used to define and categorize the graves as a group. It also investigates if the choices of concepts are depending on a broader societal perspective.To find the answers to these questions two surveys have been done.

Radioräckviddsberäkningar för flygande plattformar

There exist several known methods for calculation of radio coverage for ground-based systems. As far as we know there are no equivalent methods for the case of flying platforms when the altitudes and speeds are significantly different to those of ground-based systems. This thesis describes the theoretical concepts behind calculations of radio coverage for flying platforms. An investigation is made to sort out what is important and possible to employ in a model for simulations. A method is described and implemented in a program for evaluation of flying radio systems.

Kvickrotens reaktion på klippning och konkurrens i rajgräs- och vitklöverbestånd :

Couch grass (Elymus repens (L.) Gould) is a severe weed in Sweden, and since both the use of herbicides and cultivation should be decreased, it will become increasingly problematic to control couch. The present work is meant to, by literature studies and an experiment, give some answers to the question if cutting and competition can depress the growth of couch. The experiment was carried out in the growing season 2001 at Ultuna, Uppsala, in plastic boxes. The design was three-factorial randomised complete blocks. The factors were plant combination, nitrogen level and cutting strategy.

Distributed Operations : En förmåga eller en metod?

Uppsatsen behandlar det amerikanska konceptet Distributed Operations (DO) kopplat mot den svenska doktrinutvecklingen. Uppsatsen bygger på Mika Ihalainens uppsats om DO som en framtida upprorsbekämpningsmetod. Uppsatsen avser fortsätta på Mika Ihalainens uppsats, och då främst med hans egna förslag på vidare forskning. Syftet med uppsatsen är att besvara frågeställningen ?Är Distributed Operations en förmåga eller en metod utifrån hur konceptet nyttjades under Falklandskriget?? och att ge ett konceptexempel på hur den svenska Försvarsmakten kan hantera en lågtek-nologisk fiende samt bidraga till den svenska doktrinutvecklingen, framförallt genom en definition av begreppen förmåga och metod.

Segmentering och klassificering av LiDAR-data

With numerous applications in both military and civilian life, the demand for accurate 3D models of real world environments increases rapidly. Using an airborne laser scanner for the raw data acquisition and robust methods for data processing, the researchers at the Swedish Defence Research Agency (FOI) in Linköping hope to fully automate the modeling process.The work of this thesis has mainly been focused on three areas: ground estimation, image segmentation and classification. Procedures have in each of these areas been developed, leading to a new algorithm for ground estimation, a number of segmentation methods as well as a full comparison of various decision values for an object based classification. The ground estimation algorithm developed has yielded good results compared to the method based on active contours previously elaborated at FOI. The computational effort needed by the new method has been greatly reduced compared to the former, as performance, particularly in urban areas, has been improved.

Hantering av verksamhetskrav : Utredning av hur hantering av verksamhetskrav från kunder kan förbättras på Saab Aerosystems

Saab Aerosystems have had one dominating product, JAS 39 Gripen, and one dominating customer, FMV, for a long time. The operations management system at Aerosystems is adjusted for development of Gripen and as the business unit is trying to enter new markets with other products and customer the operations needs to be adjusted to fit the development and manufacturing of these products as well.The purpose of the master thesis has been to investigate how Aerosystems is managing requirements on operations from external customers and how to make improvements within this area. The aim has been to carry out a situation analysis to identify where improvements are possible and then produce proposals for improvements through studies of literature and other business units. The thesis also include a study of knowledge transfer within the business unit to investigate how this can be applied to improve the managing of requirement on the operations.An extensive interview study has been carried out in which interviews mainly have been conducted with employees at Aerosystems, but also at Saab Avitronics and Saab Aerostructures. The reason why these business units have been examined is because they have carried out a large number of successful businesses with external customers, which also are potential customers for Aerosystems in the future.The interviews have been analysed to identify strengths, weaknesses, opportunities and threats with the present way of working.

UAV/UCAV i fredens tjänst : UAV/UCAV och dess operativa betydelse i framtida Peace Support Operations

Luftstridskrafter har spelat en betydande roll i senare tiders Peace Support Operations (PSO). Obemannade flygande system har varit en del av dessa insatser, hur kommer rollfördelningen att vara i framtiden? Syftet med uppsatsen är att undersöka och göra en bedömning avseende hur obemannade flygsystem kan utnyttjas och ha en roll i framtida Peace Suport Operations. Litteratur- och dokumentstudier, föreläsningar och intervjuer ligger som faktabakgrund för bedömningen av hur en framtida PSO kan se ut samt vilken roll obemannade flygsystem kan ha i en framtida Peace Suport Operation. Jämförelse har skett mellan bemannade och obemannade flygande system varvid fördelar och nackdelar har belysts.

Små skogliga vattendrag i Värmland - Generell beskrivning, förekomst av traktorspår samt spårens inverkan på bottenfaunan :

Modern forestry requires a high degree of machine traffic for clear felling and scarification operations. The machines most frequently used are big and the traffic often results in tracks on the forest ground. There are many small streams running through a forest, in connection to logging operations, machines might cross these frequently. These crossings could result in the erosion of fine particulate inorganic matter, which ends up in the stream. The aim of this thesis was to give a general description of small forest streams of order-one in the county of Värmland and to determine the frequency of machine tracks in small streams.

Hänsyn till mark och vatten vid slutavverkning : en fältstudie på känsliga marker

The purpose of this study is to investigate if there is enough consideration taken to sensitive forest areas close to water or wetlands during clear cutting assignments, and to estimate the extent of damage made by forestry machines used at that time. A field and literature study is used to show how to improve and prevent the damage made in the wake of the machines. This study is made for Sydved, and shall culminate in a policy to prevent ground damage during their clear cutting assignments. The areas which were part of the field studies were clearcuttings on fine grained soil close to water and wetlands. The purpose was to find out if the water had been affected, what had been done to prevent ground damages and what more could have been done. The results of the field studies show that more work needs to be done to reach up to expectations. More information about the assignment area, better planning of sensitive regions, and strengthening of the main haul roads with brush are some of the improvements that can be done. There is also a need for more exact guidelines, follow-ups and education for everyone involved to have the same goals and understanding to prevent ground damage..

Ekonomisk styrning och kostnadskontroll vid IT-outsourcing

Background: Many companies have outsourced their IT-operations and their expectations of what this IT-outsourcing will contribute to the business are high. Cost cuts are not always a natural outcome of IT-outsourcing. Many companies that have outsourced their IT-operations consider it to be problematic and complex to exercise management control and reach cost control which was the purpose of the IT-outsourcing. Purpose: To describe and analyze what affect IT-outsourcing has on a company?s management control system and a company?s possibility to exercise cost control.

Militärteorins inflytande på doktriner : William S. Linds påverkan på svensk doktrin för markoperationer.

Influences from military theory are a part of the development of military doctrines. This thesis has, by using a method with three different dichotomies, traced and classified influences from William S Lind?s theories regarding manoeuvre warfare in the Swedish military doctrine, for land operations. The purpose has been to discuss the connection between military theory and how the Swedish doctrine for land operations (DMarkO) has been formulated. It has also been to show what this influence depends on and what consequences it will present.The examination has shown that William S.

Distributed Operations : en framtida lösning för upprorsbekämpning?

Chefen för amerikanska marinkåren beslutade 2005 att påbörja utvecklingen av konceptet DistributedOperations (DO). Syftet med konceptet är bland annat att möta utmaningarna inom upprorskrigföring och?Small Wars? som kännetecknas av asymmetriska förhållanden mellan parterna. Grundidén medDistributed Operations är att skapa en fördel över motståndaren genom att uppträda utspritt ellerkraftsamlat och hela tiden kunna avge understöd till den ?lägsta enheten?.
