A strategy for nuclear fuel bundle design optimization in boiling water reactors(BWRs), using a simplex method, is presented and examined. The objective of the study is to see how an automatic optimization scheme can create nuclear designs for use in BWR fuel bundles and how the scheme can be improved. Challenges with applying linear simplex optimization to non-linear bundle physics lie in approx
In this thesis, we address the problem of locating a passive target using a multiple-input multiple-output (MIMO) radar with widely separated antennas (WSA). Using a WSA geometry, the spatial diversity of the transmit and receive antennas are utilized to improve the localization accuracy. First, common numerical algorithms are examined, including the Newton-Raphson (NR) method with the maximum lik
Background: Supply Chain Management is receiving increased attention as companies are trying to remain competitive in a global and challenging environment. An important topic to consider when managing the supply chain is inventory control. Companies today have enormous investments in inventories, which means that there are potential improvements regarding tied up capital in raw materials, work-in-
The 21st century has brought significant changes to the market. The ability to deliver the right product at the right time with the right price is no longer just crucial for a company’s competitive success, in the long-term perspective it will decide if the company will survive on the market at all. A warehouse has a major impact on a firm’s service levels, response times and overall cost. To meet
Geofysiska mätmetoder kan tids- och kostnadseffektivt skapa tvådimensionella (2D) och tredimensionella (3D) modeller som avspeglar geologin och som kan användas som ett verktyg för kartläggning av grundvattentillgångar. I denna studie har fyra profiler belägna i den s.k. Vombsänkan i sydöstra Skåne undersökts med galvanisk resistivitetsmätning (ERT) och Transient Elektronmagnetisk Sondering (TEM)Geophysical methods can create 2D- and 3D-models that reflects the geology. These models can be used as a tool for mapping groundwater resources. Four profiles, located in Vombsänkan in southeastern Skåne, have been investigated with Electrical Resistivity Tomography (ERT) and ground-based Transient Electromagnetic Soundings (TEM) as a study of the two methods. The resistivity profiles from the g
In this thesis, an implementation of inline integration is described and examined. Inline integration is a mixed symbolic and numerical method for simulating fully implicit ordinary differential equations (DAE:s) whereby discretizations are introduced symbolically at model level. A generalized solution to the discretized model containing tailored iterative solving schemes and symbolic solutions is
Syfte: Syftet med förändringsarbetet är att hjälpa Varberger Sweden AB att skapa den fungerande produktionsapparat som behövs för att jobba enligt den av företaget utarbetade affärsidén med kärnkompetens och kundanpassning. Arbetet kommer att beskriva det använda arbetssättet, dvs. analysarbetet, men huvudsyftet är att skapa förändringar i företaget och så långt som möjligt implementera dessa. Pr
The purpose of this study was to identify the reasons behind the employees noncompliant purchasing behavior at Company X. Another aim was to find the solutions to the reasons behind the non-compliant purchasing behavior to change that behavior. This study was carried out by following an abductive approach, where a qualitative case study research was conducted. The chosen case study method was a mu
Denna uppsats behandlar två litterära verk som utspelar sig under kulturrevolutionen: Guldålder av Wang Xiaobo och Grymma bestar av Wang Shuo. I dessa verk skapar de båda författarna alldeles egna minnesbilder av kulturrevolutionen, minnesbilder som på många sätt står i bjärt kontrast till den gängse bilden av denna tid som ärrlitteraturen presenterar. Uppsatsen visar också hur de två författarna
Förhållningssättet till CSR-kommunikation i dagens forskning fokuserar mestadels på ledningsperspektivet – hur kan man kommunicera och leda CSR-arbetet på ett så effektivt sätt som möjligt? I detta examensarbete utgår jag från Communication Constitutes Organization vilket innebär att alla organisationsmedlemmars kommunikativa processer hamnar i fokus. För att uppnå syftet som är att analysera de k
In this master thesis, cold moderator flow concepts have been developed on behalf of the European Spallation Source, ESS AB in Lund. The function of the cold moderator is to slow down neutrons, generated in the spallation process. The moderation is done in liquid para-hydrogen at 15 bar and 17 K. Moderating neutrons is the primary function of the liquid hydrogen, but it also removes nuclear heat l
The quality inspection of wooden boards is experiencing a large change. By the use of camera and laser technology board characteristics and defects can be instantly identified and measured. This thesis investigates how the information from a quality inspection system can be used to classify boards into different quality classes, by the use of statistical classification models. Two types of classif
This master’s dissertation has been performed in cooperation with Tyréns and the Dept. of Construction Sciences, LTH. We have investigated if it is possible to increase the total stability for excavations with retaining structures and if each side of an excavation could be treated as a separate 2D-case with additional theories to approximate its 3D-effects. End-surface theories from the Commissio
Sydvatten är ett företag som ägs av 16 kommuner i Skåne och producerar dricksvatten till dessa. En av sydvattens vattentäkter är Vombsjön. Sydväst om Vombsjön ligger Vombverket där beredning från sjövatten till dricksvatten sker. De första stegen av beredningen sker genom att vatten från sjön pumpas in till Vombverkets infiltrationsdammar och därifrån infiltrerar ned genom den omättade zonen till Sydvatten is a company part-owned by 16 different municipalities in Skåne, south of Sweden. Sydvatten produces drinking water to these municipalities and the Vombsjö lake is one of Sydvatten´s water catchments. Southwest from the lake the water treatment installation Vombverket is found. At Vombverket the water from the lake Vombsjön is processed to drinking water. The water from the lake goes thr
The main goal of this project was to find out if objects can be given healing properties, to identify such a property and later incoprporate it in the design of an object. The final design should be realized in a full scale prototype in order to fully be able to test and analyze the result. Research was carried out in a wide research field of psychology, philosphy and religiosity in order to iden
One could argue that the responsibility of a designer increases the more consumptionbased society gets. When we focus on norms and stereotypes such as gender in the design process, it’s easy to create exclusion. By having a discussion around gender in design education, we do not only highlight the issue, we can also start to create new ways of thinking around design. With the help of my product wh
This report details the process around the makings of a board game made for the Degree Project for Bachelor of Arts in Industrial Design, spring semester 2014. The game has a background story, which is to simulate the parliamentary workings of a society teetering on the edge between autocracy and democracy and the factional struggles within its parliament. The background story sets the premise of
The original intention of this project was to explore electronic kitchenware, remove the motor of the individual gadget and build a series of hand-cranked versions of the gadgets. After initial interviews and research into food, kitchen architecture, kitchenware, trends and time measurement statistics, it became clear that induction was a technology on the rise and is quickly moving into modern ki
I början av 2013 kontaktade studenterna Danfoss Power Solutions (då Sauer- Danfoss) i Älmhult. Företaget planerade att genomföra ett Goodwill-projekt åt ARCC (Anders Rick Utbildning AB) i Ljungby. Projektets mål var att utrusta en minigrävare med ett digitalt styrsystem som ersätter delar av det mekaniska/hydrauliska styrsystemet. Minigrävaren skulle användas som utbildningsplattform då ARCC lär uAt the start of 2013 Danfoss Power Solutions (formerly Sauer-Danfoss) in Älmhult was contacted by the students. They were planning a Goodwill project for ARCC (Anders Rick Utbildning AB) in Ljungby. The goal of the project was to equip a mini excavator with a digital control system that would replace part of the existing mechanical/hydraulical control system. The mini excavator would be used as an
