Drivförstärkare : Bredbandig drivförstärkare med hög verkningsgrad
This report present the design and manufacturing of a wide-band driver amplifier placed in radar module for airborne applications. The major goals for the amplifier were a high efficiency and to deliver a predefined output power. To reach the second goal an additional preamplifier had to be constructed. The amplifiers were constructed in three steps: Design and Layout in the software Microwave Office, Mounting components and Verification. The driver amplifier was decided to be a push pull configuration consisting of two parallel transistors biased in class AB.
Jämförande analys av drivlinor och dess bränslesorter för fordon av hybrid, elektrisk och traditionell typ
The development of solar photovoltaic (PV) is increasing,with declining module prices and with a strongenvironmental profile. Policies are developed around theworld to achieve the targets set for renewable energy.In Helsingborg, the local power company Öresundskraft isworking with solar PV to achieve the goals of the city.With their vision: - Energy for a Better World and Powerfor the Region, their work with developing the local solarPV market is continuing and the next step is to create asolar PV policy. Today their offer is 1 SEK/kWh for theexcess electricity delivered to the grid.It turns out that compensating the customer is a vitalpolicy and it has to be dynamic to follow the decisions ofpolitics. The same survey shows indeed, thatenvironmental and technical part is of interest. Solar PVwill be supported locally to act on environmentalsustainability and locally produced electricity and withthis Öresundskrafts vision will be achieved..
Layoutgenerator för serie/parallell-omvandlare
I digitala kretsar kan både bit-parallella och bit-seriella interface förekomma.T ex kan en integrerad digital krets (IC-krets) internt använda sig av bit-parallella aritmetiska kretsar medan dess kommunikation med andra integrerade kretsar sker bit-seriellt. Genom att använda seriell kommunikation mellan IC-kretsar kan antalet ben på kapslarna effektivt begränsas.Detta examensarbete gick ut på att göra en layoutgenerator för generering av en parametriserbar serie/parallellomvandlare och en parallell/serieomvandlare. När en krets använder sig av både bit-seriell och bit-parallell representation av data behövs dessa för att omvandla mellan formaten..

From there, the goals forthe end-product would undergo rigorous revisions, re-de#nitionand re#nement. !e end-product itself would be the result of anentire thinking process.!e subject I have chosen is: Time. I want to challenge and evenalter our conventional sense of time, using principles ofdesign.
ZigBee-teknikens möjligheter att trådlöst överföra EKG-signaler
In many clinical applications, it is desirable to transmit sensor information wireless. In earlier research, investigation transmit ECG signal using Bluetooth, was performed. However, when Bluetooth has some drawbacks it is of interest to investigate alternative methods, one such method is ZigBee. Bluetooth has higher data rate speed (1Mbps) than ZigBee (250kbps). However, Bluetooth consumes more power.
Design and implementation of a 5GHz radio front-end module
The overall goal of this diploma work is to produce a design of a 5 GHz radio frontend using Agilent Advanced Design System (ADS) and then build a working prototype. Using this prototype to determine if RF circuits at 5 GHz can be successfully produced using distributed components on a laminate substrate. The design process for the radio front-end consists of two stages. In the first stage the distributed components are designed and simulated, and in the second stage all components are merged into a PCB. This PCB is then manufactured and assembled.
Dynamisk analys och utmattningskontroll med hjälp av fältmätningar och FEM : Fallstudie över SL:s Bro norr om Söderströmsbron
AbstractThe project "Sound and Play" have been implemented in collaboration with the toy company BRIO in Malmo. The purpose of the project was to examine whether and how BRIO in the future could develop toys around sound for Toddlers.The problem formulations that would be answered after completion of the project was "How could BRIO broaden its product range with the help of audio toys?", "How can you combine toys and sounds in an interesting way for children?", "How do you create a toy with sound that is fun for the child, but not annoying for parents?". Currently BRIO only has two toys with sound in this age group.The expression of the toy was going to be a mix of classic and cool and the overall feeling of the toy was going to be explorative and arouse curiosity in the child. This feeling would be communicated through simplicity and joy.

Täckning av plansilo :
With the increasing costs in concentrate the importance in producing ensilage with a high quality is becoming more and more important. To succeed with this goal it is of importance not only to harvest in the right period, but also to be able to store the ensilage without a decrease in quality and nutrional values. To maintain a good ensilage the covering of the ensilage must be carefully made. An unsuccessful covering causes mould to grow in the ensilage, which both increases the work load and also increases the amount of feed which is wasted. A bigger amount of spoiled feed also increases the risk of feeding spoiled feed to the cattle.
Application development for automated positioning of 3D-representations of a modularized product
This thesis presents an application that performs positioning of modules automatically based on given data for every module, and the development of it. The basis of the application is from a previous thesis code. On top of that code, more features and error handling has been added, as well as fixes for various bugs. A stress test has been performed and further development possibilities are being presented.The thesis work was carried out at Toyota Material Handling Mjölby (TMH) and was made in parallel with another thesis by Fredrik Holden who was generating data for the application. For a complete understanding of the theory and background, please also read Holden?s thesis report ?Development of method for automated positioning of 3D-representations of a modularized product?, as well as the former thesis ?Analysis for Automated Positioning of 3D-representation of a Modularized product??..
Population and management models for the Swedish wild boar (Sus scrofa)
The wild boar Sus scrofa population in Sweden has increased rapidly in the last decades which has led to conflicts among stakeholders, for example due to crop damages in agriculture. Thus, there is an urgent need of quantified goals and effective strategies for wild boar management. To develop such strategies, knowledge on population dynamics is fundamental. In this study a deterministic matrix model was used to estimate population growth, based on previously published data. The exponential growth rate for a wild boar population was calculated to 1.48.

Ökad flexibilitet i Anybus X-gateway med hjälp av Lua
HMS Networks AB develops, produces and sells communication technology for industrial automation. The product handles communication between a variety of protocols. The product treated in this project is an Anybus X-gateway Modbus-TCP Master/Client and this module is currently configured from a web-based interface. In doing so, the flexibility for handling protocols is limited to what the company chooses to add to the interface. Therefore the company had a request that the flexibility should be extended using a script language.
Automatiskt bygge av FUS39A
This paper describes the design and implementation of an automated build system for the JAS39A simulator FUS39A at HiQ:s offices in Arboga. The assignment was to automate the process in which modules are built; the simulator is composed of a number of modules which are built manually at the end of each week, this process takes about a day of manual labor. The system can automatically build a module as either a scheduled service or by manual invocation. The system contains functionality for reporting the build results to any given recipient by e-mail. The purpose of the system is to free up the time put into manually building the modules for better suited tasks by automating the build of FUS39A.The assignment was split into two parts, an analysis part where information of the old system was gathered, tools and methods were chosen and the new system was designed.
Epoxidised linseed oil as hydrophobic substance for wood protection : technology of treatment and properties of modified wood
Public concern about the release of toxic compounds from wood-based products drives legislation towards enforcing industries to find and use more sustainable solutions for wood treatment. Plant oils are good alternatives to treat wood, minimizing or even neutralizing the impact on the environment. Wood modification with epoxidised linseed oil (ELO) and acetic acid as catalyst has proven a suitable method to impregnate and protect wood. However, the mixture presents a serious inconvenience because of the quick polymerization of the ingredients that limits its practical application. Therefore, this study was designed to evaluate an alternative method using a two-step process which bypassed the problem above.
