… estimator basically contains an FFT, a windowing function and a sorting algorithm used to enable analyse of two real signals simultaneously. There were however problems during generation of the VHDL code and the model had to be broken into smaller parts containing only a …
… from unauthorized access cryptography can be applied. The cryptography algorithms in use today all have their pros and cons. They are therefore suited for different applications. We've compared three different cryptography algorithms RSA, DES and IDEA. What we've focused on is …
En utvärdering av Google och Argos med frågor från en akademisk ämnesdisciplin
… number of search facilities in comparison with Google, and that the ranking algorithm Argos uses is not advanced enough for Information Retrieval in this context. Lars Jonsson vann Collijnpriset 2003 med ovanstående uppsats.
… scanner adopts a direct method: by using a new 3D representation scheme and algorithm, the Marching Intersections data structure, we can directly intersect all the 3D volumes obtained by the silhouettes extracted from the images.
This report deals with the modeling of a part of the communication system based on the IEEE 802.11a standard which represents the next generation of wireless LAN with greater scalability, better interference immunity and significantly higher speed, up to 54 Mbps. 802.11a uses …
In this report we describe an adaptive simulated annealing method for sizing the devices in analog circuits. The motivation for use an adaptive simulated annealing method for analog circuit design are to increase the efficiency of the design circuit. To demonstrate the …
In this thesis a number of energy saving methods for a multiplier on algorithmic level are investigated. For the investigation a multiplier is constructed in VHDL, after which the circuit's performance is investigated. A number of techniques for reduced power consumption are …
… simulation system. A big number of simulations were done to optimize the algorithms, and to evaluate performance. Performance was then compared to an already existing method for terminal guidance. The new method was better in terms of angle of impact but worse considering point …
… and observations of them can be used to make the tracking more reliable. An algorithm using Kalman filters and JPDA-association to create a group track for vehicles travelling together has been implemented in Matlab. Using the state of the centre of the group the state of a …
… Subsampling add extra noise, because of that an A/D-converter based on the RSD algorithm was chosen to improve error rate. To achieve high bit-processing rate compared to the used number of transistors, pipeline structure were selected as conversion method. The receiver was that …
The Ericsson AXE-based systems are programmed using an internally developed language called Plex-C. Plex-C is normally compiled to execute on an Ericsson internal processor architecture. A transition to standard processors is currently in progress. This makes it interesting to …
… conducted by librarians. Consistency is calculated using Hoopers and Rollings algorithms. The results reveal that the level of consistency is marginally higher when using the subject headings list and words used for describing content are almost identically chosen from the five …
… Novelty perception by users, supplementing Precision. It involves traditional algorithmic performance measures, usefulness situational relevance, and non-binary relevance judgements in an operational ranked IR system seen in the context of 1 work task fulfilment, and 2 other …
… used. In the following part there is a theoretical description of the algorithms this thesis focuses on. The detection algorithms described in this paper are called Cell Average, Ordered Statistics, 2parameter and Gammadetector. Two different discriminators called Extended …
… robots and the landmarks positions are represented as states. The positioning algorithm is finally tested in indoor environment using lines and line segments as landmarks. The landmarks are extracted from measurement data from the scanning range finding laser. This master thesis …
