En j?mf?relse av tv? algoritmer
… unders?ktes ?ven hur olika numeriska metoder f?r att ber?kna dessa p?verkar precisionen och tiden det tar att k?ra algoritmerna. Rapporten visade att SVT var snabbare och gav h?gre precision ?n NIHT n?r det kommer till att komplettera Netflix-databasen. D?remot visar NIHT god …
en förstudie
… Detta gör att tekniker som samlar in data kostnadseffektivt men med låg precision blir intressanta, exempelvis radar och ultraljuds sensorer som registrerar ekon kontinuerligt medan utrustningen förs längs en linje. Om man däremot vill mäta in det sekundära samplet med sensorer …
En utvärdering av Google och Argos med frågor från en akademisk ämnesdisciplin
… for the subject of Classical Studies. The search engines are compared for precision among the first twenty results returned for thirty queries. In order to avoid bias in the study, the queries are based on real users' information needs. Due to the subjective character of the …
… based on two density variables and two external shape variables. The expected precision of the models is that they give about 70 % correct classification when sorting the logs into two quality groups. With developed log scanners and analysis methods it is possible to improve the …
ett experiment
… list of searches and gave a judgement on the relevance of their result. Thus, precision was recorded. The time to formulate a query and the length of the queries were also recorded. At the end of the experiment a short questionnaire followed to measure the students satisfaction …
Inverkan på ensilagets torkningförlopp, spill och smörsyratillväxt
… to get more even DM-content in the windrow. If you have a system with a precision chopper there is no point to use the Elho machine because the precision chopper will mix the grass and even the DMcontent. If you buy the machine, I think that you should have one with the SideFlow …

… prevent hesitation and partiality. The measure of effectivness used is top ten precision. The results of the survey were mainly positive, the difference in precision between the two languages were very low, meaning that you get mainly the same answers, if not the same documents …
… the simple search mode available for each search engine. The measure used is precision, and two different methods of measuring precision are used to give credit to those search engines that present relevant hits early in their ranked lists. Due to the subjective character of the …
en komparativ studie av olika strategier för termklustring baserade på lokal analys
… and the expanded queries are evaluated using relative recall and average precision. The study shows that all of the strategies manage to increase both recall and precision compared with the initial baseline search. No significant differences between the strategies were found.
… broader, narrower and related expansion terms. Relative recall and average precision was measured. The average results show that the expansion with inflected terms from the baseline query gave the most effective retrieval, both concerning increase in relative recall and average …
… mycket data på en liten yta. Densiteten begränsas emellertid av kravet på precision vid tolkning av den digitala datan, eftersom felaktigheter i digital data kan resultera i omfattande informationsförlust. Analog information, exempelvis ljud, är däremot inte beroende av exakthet …
… has examined the variations in chopping length depending on harvest method. Precision choppers works with a rotating chopping cylinder, where the crop is cut into pieces. The crop flow into the cylinder is determined of the specific speed of two rolls, which has influense of the …
utvärdering av en sökstrategi för citationsindex
… documents. Two questions are formulated: 1a. What is the difference in precision between the initial subject search and the citation search? 1b. What is the novelty ratio for the citation search? 2. Is there a larger proportion of relevant documents in the overlaps emerging from …
… the UGV is to be used outdoor in urban areas, GPS can be used. To improve precision and robustness, inertial navigation is used in addition to GPS, since GPS reception is likely to be diminished in such areas. The sensors used for navigation are consequently GPS, magnetometers …
… to one of the three levels; strategic, tactical or operational level. The precision of the map is enhanced by the division of the incentives into needs and arguments. Strategic needs - Centralizing, Integration Strategic arguments - Holistic fit, Process control, One company …
