Autonom bil med enkapseldator och ultraljudssensorer : tillämpning av en Arduino mikrokontrollerplattform och HC-SR04 sensorer
Autonomous cars or robot cars havebeen on the agenda ever sinceHollywood started with their Sci-Figenre, maybe even before that. A lotof things have happened since then andnow the self-driving vehicle is notfar away. In this project, theAutonomous car with microcontrollerand ultrasonic sensors, we are lookingat a way of making a small, regular RCcar autonomous with relatively simplemeans and investigate how the bigcompanies does it to learn more aboutthe development of the autonomous carsand their technology.We used an Arduino Uno R3 supplementedwith an Arduino Motor Shield R3 as ourmicrocontroller board and three HCSR04ultrasonic sensors. By removingalmost all of the old parts of the RCcar,except the two DC motors, andreplacing them with these new parts wemanaged to make a vehicle that drovearound in a room without crashing intoanything. We could have used entirelydifferent sensors, or supplemented theexisting setup with other sensors tomake it even more accurate andobstacle avoiding.
Log Search : En form av datamining
This report examines the possibility of Optimizing troubleshooting log files generated when constructing new Volvo trucks. Errors occur when CAD models are stored and managed by the versioning system PDMLink. By developing a new diagnostic tool, Log Search, the troubleshooting process is automated and thereby streamlines the current manual search..
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.
Gårdsbaserad biogas på Nya Skottorp : utvärdering och optimering av anläggningen och uppgradering av biogasen
Biogas is an expanding sector within the broad field of agriculture and animal production. Small-scale biogas offers local combined power and heating production and the substrate is transformed into high-quality biological fertilizer. This bachelor thesis focuses on a pig farm in south-western Sweden, where biogas is produced from pig manure, evaluates and suggests ways of Optimizing the process and investigates whether investing in an upgrading plant would be a feasible and more cost-efficient option. The results show that the biogas plant is working well, although the production differs from the original plans. This shows in turn that planning and examining the basic conditions before making the investment is of great importance, as well as monitoring and keeping detailed statistics of the running process.
Ledtidsreduktion i en kundorderstyrd produktion
AbstractPurpose ? The purpose of this study is to investigate possible reasons for long lead-time in a customer driven production, and how the lead-time can be reduced. To fulfil the purpose the study has been broken down into two questions.1. Whichfactorsaffectthelead-timeinacustomer-drivenproduction?2.
Integration av konstruktionsdatabas och styrsystem
The Mission at ÅF Industry in Norrkoping was about Optimizing bulk data handling while importing process tag types from their construction database into the Process Controlled System of type Siemens PCS7.I found three different methods to solve the task. Two of them were using different software from Siemens under the premise that the report from the database was corrected as needed. The third variant was manually creating the circuits. All methods worked out fine but there were times when one was better than another.To solve this task I had access to all software presented in chapter 2 ?Programvara? (=Software).

Utveckling och validering av en LC-MS/MS metod för kvantifiering av clopidogrel och dess metabolit i plasma
Clopidogrel is an antiplatelet substance that prevents blood coagulation in the arteries. It is an inactive pro drug that becomes activated after first-pass metabolism by the liver. The active metabolite of clopidogrel is 2-oxoclopidogrel, which is unstable therefore pharmacokinetic data is obtained by measuring the inactive metabolite clopidogrel acid in plasma. Clopidogrel is taken orally in tablet form. The aim of this project was to develop a LC-MS/MS method for quantification of clopidogrel and its metabolite in plasma. The method has been developed by Optimizing the sample preparation.
Sänkt returtemperatur : Potentiell besparing i fjärrvärmesystem
Optimizing energy systems is, in Sweden, as in many other countries, of growing interest. District heating systems are no exception. In 2012, 285 out of 290 municipals in Sweden had district heating in use and the majority of these systems have a higher return temperature than that which is possible with an error-free substation of day current technology. To, when possible, lower the return temperature is a way of increasing the effectiveness of the district heating system.This study means to investigate, through simulations and calculations, how big of a reduction in production cost a lower temperature in the city of Ystad?s district heating system would correspond to.
Att optimera samhället inför klimatförändringar : Sårbarhet och anpassning på dagordningen
This thesis examines the ways in which adaptation and vulnerability are framed in national and sectorial policy-documents dealing with expected societal impacts of climate change. By using theories of discourse and ideology, the analysis aims to find and understand important ideas and presuppositions that are explicitly or implicitly expressed in these documents in order to make possible and tangible the institutional production of policy within the potentially far-reaching problematique of climate change adaptation and vulnerability. The analysis shows that there are two main perspectives through which vulnerability and adaptation are framed; one focusing limits to societal robustness; and one contesting the institutional capacity to implement adaptations. The author understands these framings as complementarily Optimizing preconceived social and economic relations, something that might, in fact, reduce the response capacity of people..
Lokal logistikoptimering för ENA Energi i Enköping
The cost for forestry logistics in Sweden is about 25 percent of the total cost of getting the raw material to industry (Anon., 2010). There might be much to gain by taking a look at your supply chains on the logistic side in your company. In this report the logistic chains by Mellanskog for ENA Energi AB in Enköping has been looked in to. ENA Energis plant is a combined power and heating plant and about 99, 5 percent of their fuel consisted of bio energy in year 2009 (ENA Energi, 2011, länk A).
The main purpose with this report is to look at three questions:
1. How does the supply chain look today? From forest to industry.
2.
Sammanställning och produktion av ritningsunderlag till båt
Hanterbara båtar is a new company who builds alumina boats customized for people in wheelchairs. Due to the fact that the company only built two boats yet, the production documentation is not complete. The drawing that does exist is not in an exact standard which makes production planning harder.The purpose of this work has been to make the production of the boat easier and simplify further development and modification. Product development in the form of Optimizing details is also one of the main purpose of this work.This is all done by making a 3D-assembly of all the existing drawings. After this is done new drawings will be made and added to the main assembly.

Bygelstolpar : Kraft- och spänningsanalys av bygelstolpar tillhörande Bruks mobila hugg 805 CT
This report is the result of a thesis as been implemented during the spring term 2009 atthe University of Gävle.The company Bruks produces mobile chippers which are used for chipping loggingslash, roundwood and parts of trees. The chipper is powered by a separate diesel engineand the chipper can be assembled on trucks, trailers or some other carrier vehicles.When the chip has passed the chipper drum, the chip is collected in an integrated binwhich is mounted on the vehicles frame with dumping yokes. When these dumpingyokes were designed they were probably created with large material dimensions. Theaim with the degree project is hence to study the strengths of materials and, if possible,to suggest an arrangement that can decrease the total weight on the dumping yoke onBruks´ mobile chippers 805 CT.The CAD-program Pro/ENGINEER was used during the project for outlining the 2Ddrawings,as distributed of constructors on Bruks, to solid 3D-parts. The three-dimensionalassembly from Pro/ENGINEER was transferred to Pro/MECHANICA.
