A feasibility study
… this master degree project was to investigate how to implement a receiver in a data transfer system. The system consists of several data channels, where every channel consists of three parts: driver, transmission lines and receiver. The driver send low amplitude differential …
… sensor images generated by PMSIM to other simulators or desktop computers. The transmission is band-limited so some kind of image coding must be used. Because of this the greater part of this thesis is concerned with image coding. To fulfill the real time requirement the image …
… markets, Denmark, Finland, Norway and Sweden. The research is based on primary data, existing theories and earlier studies regarding international transmission of stock market movements. The examined method is a VAR (Vector autoregressive model) including a 10x1 vector of …
the curious case of a water- and mosquito associated bacterium in Sweden
… of the bacterium, hence this literature overview aims at compiling data regarding the aquatic association and the role of mosquitoes in transmission of Francisella tularensis subspecies holartica, the sole subspecies in Sweden. While a linkage between the bacterium and natural …
… is under development. Today the standard of the bus supports transmission of data with a speed of up to 400 Mbit/s. In the future FireWire is supposed to transmit data with a speed of up to 3,2 Gbit/s. The thesis gives an introduction to the technique for FireWire and how it is …
a price transmission analysis of wheat
… time series, a Vector Error Correction Model is applied. Monthly time series data from Swedish Board of Agriculture and global price data from the World Bank is used. Initially the price series have been tested for non-stationarity and showed significant results, thus trended …
Code Division Multiple Access
Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same …
Metoder för omvandling av relationsdata till hierarkisk data
The relational database model was defined in the 1970?s and is the dominating database type today. The main difference between data from a relational database and a hierarchical data structure is that the relational database stores records in tables. The records have no …
osäkerhetskällor för nätverks-RTK
… Satellite Systems (GNSS). The technology means the use of correction data from a network of GNSS receivers with known positions (reference stations) to reduce the uncertainty in position for the user´s GNSS receiver (rover). However, this requires that the correction data can be …
… that weconducted a group interview as well as individual interviews.Based on data from the interviews and our preliminary work a prototype wasbuilt. This prototype is a fluorescent fixture equipped with 2x14W T5fluorescent lamps, dimmed separately. The shape can be described as …
… implementationen av ett mjukvarusystem utformat för att hämta och presentera data från Internetanslutna sensorer. Idén bygger på ett koncept av Jerry Lindblom vid EISLAB på Luleå tekniska universitet. Utvecklandet har skett i nära samarbete med Gema Industri AB med målet att …
En kvalitativ fallstudie av dold viral PR
… six contributors of three different campaigns, using covert PR. The primary data consists of the empery of the interviews, while the secondary data consists of a theoretical framework of excellence in public relations, the PR practice and viral messages. The result of the study …
… 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 …
… att lösa detta problem så måste man strukturera och organisera lagringen av data, ända arbetsorganisationen och arbetssättet runt användandet av CAM-verktyget.
… än hos den ursprungliga energiväven, dessa värden kan i sig ge användbar data inför framtida produktutveckling.
