Implementation av ett kunskapsbas system för rough set theory med kvantitativa mätningar / Implementation of a Rough Knowledge Base System Supporting Quantitative Measures

Andersson, Robin January 2004 (has links)
<p>This thesis presents the implementation of a knowledge base system for rough sets [Paw92]within the logic programming framework. The combination of rough set theory with logic programming is a novel approach. The presented implementation serves as a prototype system for the ideas presented in [VDM03a, VDM03b]. The system is available at "http://www.ida.liu.se/rkbs". </p><p>The presented language for describing knowledge in the rough knowledge base caters for implicit definition of rough sets by combining different regions (e.g. upper approximation, lower approximation, boundary) of other defined rough sets. The rough knowledge base system also provides methods for querying the knowledge base and methods for computing quantitative measures. </p><p>We test the implemented system on a medium sized application example to illustrate the usefulness of the system and the incorporated language. We also provide performance measurements of the system.</p>

Studium vybraných faktorů na hospodářské vlastnosti silážní kukuřice / Study of selected factors influencing maize for silage agronomic attributes

KADOUN, Lukáš January 2011 (has links)
In the years of 2009 and 2010, an observation of chosen quantitative and qualitative measures of several hybrids of corn took place at PS Humpolec and ZD Hosín. Quantitative measures were evaluated based on dissection of individual plants, qualitative measures then through common laboratory methods. In the field experiments at PS Humpolec, an observation of the seeding quantity and nitrogen load took place. The seeding quantity influenced with very high size of effect all agronomical and seed figures, except for the number of rows in the cob, where only high size of effect was observed. The quantity of 85 thousand seeds per hectare seems to be optimal. The nitrogen load influenced with very high size of effect the weight of the cob, with high size of effect the number of cobs and the weight of grains in the cob. Other measures were not affected. The year influenced with very high size of effect the length of the plant, the number of leaves, the weight of the cob; with high size of effect the height of the first cob on the plant and with considerable size of effect the number of cobs on the plant and the length of the cobs. Other observed measures were not affected by the year. Optimal nitrogen load that can be recommended is 110 kilograms per hectare. The best digestibility was noted with 100 thousand seeds per hectare and 110 Kg of nitrogen per hectare, or with 70 thousand seeds per hectare with no nitrogen. In the operational and half-operational experiments at ZD Hosín, differences between chosen hybrids were observed. Based on the results, the best one that can be recommended for these environmental conditions is Karacho, with FAO 260. Hybrid Karacho achieved the highest yield of matter in both years and in the year of 2010 it also achieved the best digestibility.

From Snow White to Frozen : An evaluation of popular gender representation indicators applied to Disney’s princess films / Från Snövit till Frost : En utvärdering av populära könsrepresentations-indikatorer tillämpade på Disneys prinsessfilmer

Nyh, Johan January 2015 (has links)
Simple content analysis methods, such as the Bechdel test and measuring percentage of female talk time or characters, have seen a surge of attention from mainstream media and in social media the last couple of years. Underlying assumptions are generally shared with the gender role socialization model and consequently, an importance is stated, due to a high degree to which impressions from media shape in particular young children’s identification processes. For young girls, the Disney Princesses franchise (with Frozen included) stands out as the number one player commercially as well as in customer awareness. The vertical lineup of Disney princesses spans from the passive and domestic working Snow White in 1937 to independent and super-power wielding princess Elsa in 2013, which makes the line of films an optimal test subject in evaluating above-mentioned simple content analysis methods. As a control, a meta-study has been conducted on previous academic studies on the same range of films. The sampled research, within fields spanning from qualitative content analysis and semiotics to coded content analysis, all come to the same conclusions regarding the general changes over time in representations of female characters. The objective of this thesis is to answer whether or not there is a correlation between these changes and those indicated by the simple content analysis methods, i.e. whether or not the simple popular methods are in general coherence with the more intricate academic methods. / <p>Betyg VG (skala IG-VG)</p>
