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?.
3D-modellering i AutoCAD -att skapa en digital huskonstruktion
3D-modelling in AutoCAD This thesis is done in cooperation with LB-Hus in Bromölla, and have aimed to establish a digital AutoCAD model of one of the company?s house types and to find out what opportunities there are to do visualisations in the form of images directly from the programme. Modeling has been carried out so that the very construction of the house is included. Interiors and installations, with the exception of the ventilation system, have been left out in the model. The model has been created with solid models after a comparative study made between solid models and surface models to find out which option in this case was the easiest to handle and took up the least space.
Kopplingen mellan Livscykelkostnader och Building Information Modelling
Detta examensarbete har undersökt vilka möjligheter som skapas genom att använda BuildingInformation Modelling (BIM) för Livscykelkostnadsanalyser (LCCA). Arbetet beskriver förstLCCA och sedan hur BIM samt öppna standardiserade dataformat kan användas för LCCAoch för kvalitetssäkring av data. Till sist visas hur ett verktyg som räknar ut LCC direkt frånen byggnadsmodell kan utformas. Genom att kunna synliggöra konsekvenserna av olikalösningsalternativ och göra kvalitativa LCCA erhålls genomtänkta lösningar och medvetenhetom de framtida förvaltningskostnaderna. För en byggherre som också ansvarar för driften kandessa alternativsvärderingar och analyser leda till betydligt lägre förvaltningskostnader.
Realisering av returer vid rundvirkestransport med lastbil : hinder, möjligheter, vinster och vinstdelning
Holmen Skog, region Norrköping, is located in an area with good potential for backhauling because a large number of geographically scattered mills. However, despite these factors there are many difficulties preventing the realization of this potential. The purposes of this study were twofold. First, from a hauling contractor perspective, to calculate backhauling profits and suggest a profit sharing scheme. Second, to identify and quantify obstacles and possibilities for realization of backhauls.The study required the use of three different types of methods.
Major vs. Independent : en undersökning om hur skivbolagsrepresentationen ser ut i svensk dagspress
Aim: The aim for this study of Swedish daily press is to see how the musical reporting is structured for the newspapers I have chosen to analyse. My main purpose is to investigate how the newspapers reporting are distributed between artists who belong to either a major record company or an independent record company. With this research I want to find out if there are any economic backgrounds to the content and if the reporting is equal to the market production.Method/Material: For this study I have studied, by quantitative research, every piece of musical reporting in seven daily newspapers for two weeks. Through thorough research I have determined the belonging of every article?s record company.
Förbättring av mjukvarubibliotek för parallellberäkningar med programmeringsmodellen Chunks and Tasks
Chunks and Tasks is a programming model based on the C ++ programming language. This programming model is used for electronic structure calculations, among other things.The purpose of this project is to improve the CHT-MPI software library for Chunks and tasks, so that calculations of matrix-matrix multiplications are performed more efficiently than they do with the existing software library. The software library is based on the work stealing method, which is a method the software library for Chunks and Tasks uses for the distribution of the calculation work. The considered way to improve the software library is by modifying the work stealing method in a way that makes the distribution of calculation work happen in a more efficient way , which will lead to calculations performed faster than before.Two different modifications of the work stealing method were tested and it led to two new methods, Method 1 and Method 2, which distributed the calculation work differently. Method 1 did not give results that were compatible with the theory, since the calculation time with this method was much longer than the previous method.
Inre- och yttre motivation med SDT som förklaringsmodell : En studie av Sandvik Tooling
Title: Intrinsic- and extrinsic motivation with SDT as a model of explanation ? A study of Sandvik Tooling Level: Final assignment for Master Degree in Business Administration Authors: Samuel Norman & Erik Sandh Supervisor: Jonas Kågström Date: 2011 ? June Aim: From the basis of Self-Determination Theory find those motives that are the sources of the greatest motivation at Sandvik Tooling and determine if the employees are mostly driven by intrinsic- or extrinsic motivation. Method: The study has a quantitative approach where the empirical part consists of 24 questions from the SDT-theory?s Aspirations index that is divided into six groups evenly distributed on intrinsic- and extrinsic motivations. The questionnaire has been developed in Google forms and distributed digitally to the organisation by e-mail through a contact person at Sandvik Tooling. The respondents? answers are accounted for question by question in the empirical chapter and have been processed with a factor analysis and compared with the SDT-theory.Result & Conclusions: The results we received are in line with SDT-theory and whether people are motivated differently by intrinsic-Personal growth and Community contributions higher than all of the extrinsic motivational factors.

Avskiljning av ammoniumkväve och fosfatfosfor i reaktiva filtermaterial : skak- och kolonnförsök
In Sweden more than 400 000 private households have not yet sufficient wastewater purification. These effluent is considered as an increasing problem and many onsite purification methods have been studied. In this investigation, the method of reactive bed filters have been tested by column and batch experiments. Five different kinds of filter materials with reactive surfaces have been studied concerning their capacity to absorb ammonium and phosphorus from wastewater. The materials that were examined are Filtra N, wollastonite Filtra P, blast furnace slag and Polonite®.
DDoS: Ett evolverande fenomen / DDoS: An evolving phenomenon
Internetfenomenet ?Distributed Denial of Service?, förkortat DDoS, beskrivs ofta som ett av de
största hoten mot Internet idag. Genom att utnyttja den grundläggande strukturen i kommunikation
mellan nätverk och datorer kan kriminella blockera och stänga ute webbplatser och -tjänster från
användare, samtidigt som det är mycket svårt för offret och myndigheter att någonsin identifiera
den eller de skyldiga. Enorma globala nätverk av ovetande människors infekterade datorer fjärrstyrs
till att utföra angrepp mot alla sorters organisationer på Internet med olika motiv, som finansiella,
politiska eller för ren vandalism. Syftet med det här arbetet är att göra en dagsaktuell kartläggning
över läget kring DDoS-angrepp och titta på statistik över de mest förekommande angreppstyperna,
och se om den nyare publicerade forskningen kan svara på de pågående och framträdande trender
som kan ses.
Identifiering av deponerat material i en deponi samt metodikförslag för upprättande av vattenbalans.
Högbytorp is Ragn-Sells? largest waste facility and it is located north of Stockholm. There is an old landfill still in use, but at the end of this year it will be closed. The waste deposited on the landfill can, through decomposition, give rise to a large amount of methane gas, which is an energy rich gas that can be used for heat and electricity production. To receive a relatively large amount of gas, the decomposition requires a high moisture content in the waste.
Optimering av fackverksmodellering : Ett makro för Tekla Structures
This project is the result of a cooperation between HalmstadUniversity and EABAB. The aim of the project was to create a macro that would help EABAB automate the process of designing steel trusses. When run in Microsoft Excel, the macro imports and processes coordinates from a calculator program. The data is then imported into the Building Information Modelling software Tekla Structures, which creates a 3D structural model of the steel truss.The macro saves much time in the project planning process and also helps minimize the risk of design flaws caused by human error. .
?Jag är en av de få som blir lycklig...? - bibliotekariers attityder och förhållningssätt på fem folkbibliotek till statens distributionsstödda titlar.
The purpose of this master?s thesis is to study attitudes and standpoints among a few librarians towards literature with state supported distribution provided by the Swedish Arts Council. By qualitative interviews with librarians at five different public libraries, the thesis examines which attitudes that flourish concerning the titles, how the circular of books is treated, where the titles belong on the literature map and if the system is producing a standardisation of this literature and if the conception of quality is relevant. We also study how the librarians relate to intentions of the Swedish Art Council with the distributed titles and how they regard their availability. Our theoretical framework is based on Hans Hertel?s model of five literary circulations and Theodor W.
ITS under byggtid - utvärdering med dynameq : Fallstudie: Intunnling av E4/E20 Tomteboda - Haga södra
Essingeleden in Stockholm is the most heavily congested road segment in Scandinavia and it is ofgreat importance for as well traffic within the city as for transit traffic. The capacity of Essingeledenand Norra Länken is not enough to accommodate all traffic. At times it is not moving at all, whichresults in long queues and an augmented risk of accidents. Consequently measures for increasing thecapacity on E4/E20, which will reduce congestion and the risk of accidents, are implemented byTrafikverket. In fall 2012 one lane of three at Pampas will be closed and so will the exit fromEssingeleden to Norra Stationsgatan, called Parkeringsbron.
Regressionsmodellering av dynamiska råemissioner från statiska mätningar
By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.
