The report handles the Transmission of signals from piezoresistive pressuresensors and thermocouple from a rotating object. This report also evaluates the possibility to collect data in a datalogger that rotates with the object. Telemetrics was previously used for signalTransmission in Finspång, therefore there has been no tests considering preassure measuring. One transmitting method handled in this report is Transmission through a slipring connection. One test with a slipring connection was performed for transmitting signals from a piezoresistive preassuresensor.

In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the Transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.

The purpose of this master thesis is to construct a steering Transmission, for a trackedvehicle, containing two hydraulic circuits which are connected. The steeringTransmission should be mechanical to avoid steer-by-wire.BAE Systems Hägglunds has in an earlier study examined a system with two hydraulicpumps and one hydraulic motor, but the safety of the system wasn?t sufficient.To achieve sufficient redundancy there must be two hydraulic motors, which arecontrolled separately. When the two systems are connected in one point, this point is acritical part of the system because it directly affects both circuits. If one of the hydrauliccircuits fails the other should be able to operate independently as a steeringTransmission.

Increased trade and eased policy restrictions have brought markets closer together. Prices at different locations are much likely to affect each other to a certain extent. Since the adaption of Common Agricultural Policy in 1995 the Swedish wheat market has been exposed to the world market and Swedish farmers are facing new challenges. A broader knowledge about market integration and price Transmission will facilitate Swedish farmers, banks and politicians in making rational decisions. Therefore the aim of this research is to explain how global wheat prices are transmitted on Swedish wheat prices.

The conservation of great apes faces many challenges, one of which is the threat of infectious disease outbreaks. Zoonotic Transmission of respiratory diseases from humans to wild great apes has recently been confirmed. Since respiratory disease is one of the major causes of death in both gorillas and chimpanzees, this gives reason for major concern. Little is known about the risks of disease Transmission from humans to great apes in natural environments, and there is a need for systematic risk evaluation. Researchers, conservation staff and tourists spend time in very close proximity of wild great apes, sometimes during long time periods, which poses a potential risk of disease spillover. However, the presence of researchers and tourists has been shown to decrease the risk of poaching, making the matter increasingly complex.

Purpose: This study aims to examine the price Transmission among ADRs (American Depositary Receipts) and their underlying shares, US market index and Hong Kong market index. We will attempt to capture how a shock in the home market is transmitted to the foreign (and vice versa). In addition we will attempt to assess the relative weight of each variable in the system generating unexpected variations of its own and other variables and at what speed the shocks are absorbed.Methodology: ADF unit root test, Johansen?s co-integration test, Granger causality test, VECM, impulse response, variance decomposition Empirical foundation: Five Chinese ADRs listed on the New York Stock Exchange. Each ADR represents a specific industry.

Det finns studier som visar att skador i Transmission och hydraulik är bland de vanligaste och dyraste skadorna på traktorer. Ytterligare studier visar att det finns mycket partiklar i oljorna hos lantbrukets traktorer. Även om inte partikelmängden som sådan är orsak till skadan kan den orsaka följdskador, ofta med stora kostnader som konsekvens. Partiklarna kan komma från både inre och yttre källor. Partiklar som uppstår i traktorn uppkommer på grund av olika slitage på materialen i traktorn. Partiklar som kommer utifrån och genom yttre faktorer kommer från till exempel luftningen på hydrauliksystem eller från slarv vid påfyllning av olja.

Numerical simulations play a vital role in both static and dynamic stability assessment of electric power systems and the foreseeing of voltage collapse. Simulations performed by Svenska Kraftnät(SvK) are mainly done in the specialized voltage collapse predicting software tool, SPICA and the more all?purpose software tool, ARISTO.The grid operators at SvK use SPICA to predict the maximum transfer limit at specified sections (in this report the section in concerns is the southern part of Sweden i.e. interface1 4). SPICA is mainly used as an online application by using actual states from the grid, these states update every quarter of an hour.This thesis is a continuation of the master thesis SPICA ? ARISTO JÄMFÖRELSE by Jakob Katzman and Johan Fält.

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

The majority of all power cuts that affects individuals and communities are caused by earth faults on the power Transmission lines at 10kV and 20kV level [1]. If these power cuts could be eliminated, less disturbances and interrupts would lead to large amounts of money savings.Swedish Neutral has developed such a protection system. When an earth fault occurs power is injected into the neutral point of the transformer. The RCC (Residual Current Compensation) protection calculates a compensation current exactly 180 degrees out of phase to the fault current. Doing this, the voltage at the fault location becomes very close to zero, without affecting the power Transmission.The protection system can only compensate automatically for the fundamental frequency (50Hz), and manually for the 3rd, 5th, 7th and 9th harmonics.

Metoder och system för mätteknik får en allt större betydelse för moderna tillverkningsföretag. Allt fler företag har insett det strategiska värdet av en förbättrad kvalitetsuppföljning för att minimera kostnader på grund av kvalitetsbrist. Syftet med denna rapport är att ta fram en strategi för standardisering av kontrollmätningen vid den nya typ av mätplats, en Q-plats, som ställts upp inom avdelning DXMH vid Scania Transmission. Q-platsen ger möjligheter för operatörerna att i större grad själva genomföra kontrollmätningen i närheten av produktionslinjen. I rapporten analyseras först Q-platsens funktion utifrån en studie av Scania Transmission DX, dessutom redovisas fallstudier på andra avdelningar inom Scania och vid andra tillverkningsföretag.

In modern industrial robots the components in the Transmission contain nonlinearities. These nonlinearities need to be to estimated either for better control or to use the parameters for diagnosis of the system. There is a lot of work done within system identification and mainly within the field of iterative parameter estimation.This thesis considers recursive grey-box identification for a nonlinear model of the Transmission in an industrial robot. The nonlinearities that are identified are friction, spring stiffnes, hysteresis and backlash. These nonlinearities are a part of the models that are presented in this thesis.

Husaberg Scandinavia AB is a company producing and developing a range of motorcycles for both on- and off-road use. Husaberg provided the project group with a task of developing an entirely new way of operating the sequential Transmission that can be found in today?s motorcycles. The target was to bring the product from idea to a functional prototype ready for further tests. Operation of the motorcycles Transmission is today made by a foot pedal placed on the left hand side of the bike.

Syftet med detta arbete är att analysera hur Ringhals reaktor II kan ersättas med hållbar energiproduktion. Detta görs genom att analysera vilka produktionstekniker som är kommersiellt gångbara i Sverige. Sedan analyseras dessa utifrån dess geografiska och tekniska begränsningar i regionen Västra Götaland och Halland för att bestämma hur den nya energimixen kan utformas. Utifrån energimixen simuleras sedan energiproduktionen i elzon 3, SE3, under varje timme över ett år för att undersöka om den nya produktionen kan möta efterfrågan och huruvida elnätet kommer att belastas hårdare på grund av eventuell ökad Transmission till/från andra delar av landet. Från energimixen beräknas även vad produktionskostnaden för elektriciteten blir för den alternativa produktionen. Resultatet visar att den föreslagna energimixen klarar av att ersätta energiproduktionen från Ringhals reaktor II med endast en marginell ökning i Transmission till/från regionen.
