Generaliseringsförmåga vid genetisk programmering

I detta arbete undersöks hur bestraffningsmetoder för att bestraffa storleken på GP-program påverkar generaliseringsförmågan. Arbetet grundar sig på ett arbete som Cavaretta och Chellapilla gjort, där de undersöker skillnaden i generaliseringsförmåga mellan bestraffningsmetoden ?Complexity Penalty functions? och ingen bestraffningsmetod.I detta arbete har nya experiment gjorts med ?Complexity Penalty functions? och ?Adaptive parsimony pressure?, som är en annan bestraffningsmetod. Dessa bestraffningsmetoder har undersökts i samma domän som Cavaretta och Chellapilla och ytterligare i en domän för att ge en bättre bild av hur de generaliserar.I arbetet visar det sig att användningen av någon av bestraffningsmetoderna ?Complexity Penalty functions? och ?Adaptive parsimony pressure? oftast ger bättre generaliseringsförmåga hos GP-program.

Balancing packaging complexity by introducing platforms - A study at Carlsberg Breweries

Many consulting firms offer tailor-made solutions within complexity management, but these are not general frameworks built upon theories. Carlsberg are dealing with a large complexity within their one-way glass bottles, as they are growing by acquisitions, and are not attained enough economies of scale. This thesis balances the packaging complexity, with platform theory as a foundation. Twelve platforms were developed at Carlsberg, containing 21 bottles, and the calculated savings potential for applying these are EUR 28,9 million..

En jämförelsestudie av JavaScript-bibliotek Med fokus på mjukvarukvalitet

JavaScripts popularity is increasing and the number of libraries too. This report focuses on well-known software metrics in complexity, maintainability and different size-metrics. A few different JavaScript libraries are compared and analyzed. The result shows that there are indeed differences, mostly in size- and complexity-measures where some functions are implemented with a higher complexity..

Trycksårsprevention - en litteraturstudie/Prevention of pressure ulcers - a literature review

Furthermore, the purpose was to identify the most common location of pressure ulcer and to examine whether there were any connection between risk factors and possible pressure ulcers.

Energianalys av tryckluftsystem : så kan Billerud Skärblacka AB spara energi på tryckluft

Compressed air is a low efficiency media, and is thus very expensive to produce. This thesis work began by mind mapping how to create savings on the compressed air system at Billerud Skärblacka AB. Certain issues have been chosen for further studies.In order to identify the consumption of compressed air at PM 8 and 9, several measurements were made. At PM 8 there were not found any pressure drop, only large pressure variations for short periods of time. The causes of these pressure variations were not established.

Effekten av massagebehanling vid hypertoni : en litteraturstudie

Aim: The aim is to create a review that examines different forms of massage therapy and their effects on hypertension.Method: Literature review of 10 scientific articles on the subject of massage and its effects on blood pressure. The literature searches were made with PubMed and Cinahl using the keywords "massage therapy", "effects" and "blood pressure".Results: The articles showed that massage had a positive effect in lowering blood pressure. This could be explained by greater extent of relaxation in the participants investigated and an increased activity of parasympaticus and reduced secretion of stress hormones. The articles do not agree on what form of massage therapy is most effective in lowering blood pressure and it is uncertain for how long the effect can remain.Conclusion: Massage is usually seen as a treatment without scientific basis. There is evidence that suggests that massage therapy is an effective treatment for lowering blood pressure.

Att leva med trycksår - en litteraturstudie om hur patienter med trycksår upplever det dagliga livet

Hur episodisk hypoxi p?verkar blodtrycket hos friska ?ldre individer

Aim and Hypotheses The aim of the study was to investigate how episodic hypoxia affects resting blood pressure and the acute blood pressure response in healthy older adults. The following hypotheses were formulated for analysis in the study: Blood pressure increases acutely in healthy older adults during exposure to 150 minutes of hypoxia with SpO? 80%. Resting blood pressure decreases in healthy older adults after 15 repeated exposures of 150 minutes of hypoxia with SpO? 80% over a period of three to four weeks.
