Modellering och reglering av mjölkningsrobot
In this master thesis a robot arm belonging to an automatic milking machine from DeLaval is investigated. The robot arm is controlled by a pneumatic cylinder and a valve. The goal of the master thesis is to investigate instability problems and to find out if it is possible to solve them by using gain scheduling. Gain scheduling is a type of controller where the parameters of the controller are changed during operation, for example depending on the working point. First a nonlinear mathematical model of the system was made.
Skotares bränsleförbrukning :
In published studies it is found that the fuel consumption on a forwarder is relatively constant, on time basis. A certain variation between different sizes of forwarders occurs as well as between different working elements.
The aim of the study was to establish a forwarders comparatively fuel consumption when driving on road and in the terrain, loaded and unloaded, with high and low gear and with high and low speed as well as with hydrostatic and hydrodynamic transmission. A hypothesis was that low rpm gives lower fuel consumption on distance basic, at all trials.
The test driving was made with a Hemek 750 which is a three geared hydrostatic machine and with a Hemek 700 which is a hydrodynamic machine with six gears.
Koldioxidutsläpp vid vägbyggnad - en fallstudie med jämförelse av alternativa byggnadssätt
Abstract This degree project examines how much carbon dioxide that emits during the construction phase of a road project. This is to make it possible to compare how the amount of carbon dioxide differentiates between traditional road construction and Swepave construction, which is PEAB?s alternative way to design roads. To make the comparison a calculation tool has been produced. To compare the amount of carbon dioxide emissions a reference project was needed.
CE-ma?rkning av produkter under byggproduktfo?rordningen
The purpose of this study is to achieve an understanding of how a CE- marking process is conducted and to identify the relevant factors that must be considered in such a process. We have conducted our study at Lo?vhults Svets & Smide AB (Lo?vhults) in Skruv, Sma?land Sweden, which are manufacturing brackets for small covering constructions.To understand how a CE-marking process is conducted several documents and provisions have been reviewed to achieve a basic understanding and insight of the subject. It thus led to that guideline ETAG 015 were studied and the factors to be considered in the CE-marking of brackets were identified. Together with Jan-A?ke Johansson at Lo?vhults we agreed on four different brackets to investigate for a potential CE-marking.
Studie utav ett larmsystem ur ett signalteoretiskt perspektiv : Study of a detector by a signal detection theory
In present-day situation many libraries use detectors so that they can be able to prevent attempts too take out books without registering them. The university library in Jonkoping is one of the libraries that have such a detector. But unfortunately it doesn?t always work correct and can also react on other things a part from books. This is a big problem since the library staff don?t have time to check all signals that comes from detector.
Fallstudie på växtodlingsgård :
This report will point out the income for a scania plant production farm, this has been
estimated through a case study. The outcome of this report will later be used to
calculate a reasonable leasehold charge.
This case study is solitary based upon this particular studied farm, at this very point,
and can therefore not be used as a general guide. The reason why this particular scania
plant production farm has been selected, is because the author is born and raised at the
farm and has the intention to run the farm in the future.
The chosen farm for this report is based in the southwest of scania and cover 300
hectare of plant production. The crop rotation consists of autumn wheat, sugar beats,
spring wheat, spring barely, winter rape and fallow. The farm owns all machinery
required.
Spelar geografi roll? : En studie av Bolognaprocessen ur ett policy transferperspektiv
AbstractDoes Geography Matter? A Study of the Bologna Process from a Policy Transfer Perspective.Essay in Political Science (D-level) at Karlstad?s University by Beatrice Högå, Spring 2007Tutor: Susan MartonThe purpose of this essay is to generally see how theories of policy transfer can help us to better understand the process through which the Bologna Process is being spread throughout Europe, and to specially see if geographic placement, i.e. in the heart of Europe, plays a role in how well and how fast the Bologna Process is implemented.To be able to answer the purpose, I have used Evans and Davies theoretical model on policy transfer network to describe the Bologna Process. Furthermore, Sweden and France are the countries being examined when they differ on the independent variable. From there, I have applied an analytical tool, namely process tracing, to examine whether there are differences in the two countries? work with the implementation of the Bologna Process.I have designed six specific research questions:Have France performed more extensive work than Sweden when it comes to implement the two-cycle system?Have France performed this work earlier?Have France performed more extensive work than Sweden when it comes to recognize awards and periods of study?Have France performed this work earlier?Have France performed more extensive work than Sweden when it comes to quality assurance?Have France performed this work earlier?After applying the analytical tool to be able to answers these research questions, the answer to the general question Does geographic placement, i.e.
Design av PID-regulator baserad på kommersiell processormodul
The idea to develop a platform for a PID-controller came from the need to control the temperature in an espresso machine in a more exact way than a thermostat could perform. In discussions with Syntronic AB the idea developed into PID-control for industrial use. Syntronic AB suggested that the platform should be based on a commercially available processor module to shorten the development time. The suggestion included the use of the microcomputer Raspberry Pi, which supports USB, HDMI, memory card and Ethernet.The work began with establishing a schedule for the 10 weeks of the projects duration, and after that a system specification listing all functions, implementation and limitations was made. When the foundation of the system specification was done, a preliminary system design took shape.Because of the Raspberry Pi´s lack of Analog-to-Digital converter, a circuit board containing Wheatstone bridges, differential amplifiers and a two channel Analog-to-Digital converter was fabricated.

Motviktsslungans dynamik : En analys av medeltida konstruktionsråd för mekaniskt artilleri
AbstractThis Master?s thesis analyses the dynamics of the medieval counterweight lever engine, ortrebuchet, a type of mechanical artillery. The purpose is to study the differences between different types of these machines, and see if computer simulations can be used to validate preserved advice on construction. Simulations include machines with a fixed counterweight, a hinged counterweight and a combination of both counterweights.Due to the almost complete lack of archaeological finds and insufficient historical source material there are still, after more than a century of research, many unanswered questions concerning the design and performance of these machines.The present study is based on an analysis by Jahsman (2004). A more detailed mathematical model employing Coulomb-friction is used.
