Comparison of two methods for evolving recurrent artificial neural networks for

n this dissertation a comparison of two evolutionary methods for evolving ANNs for robot control is made. The methods compared are SANE with enforced sub-population and delta-coding, and marker-based encoding. In an attempt to speed up evolution, marker-based encoding is extended with delta-coding. The task selected for comparison is the hunter-prey task. This task requires the robot controller to posess some form of memory as the prey can move out of sensor range.

Bayesiansk klassificering av ursprung för fångster av sill

Sammanfattning I september 2008 fångades 311 juveniler (unga individer) av arten sill (Clupea harengus) in vid fyra olika områden på den svenska västkusten; Råssö, Hunnebo, Askerö- och Gullmarfjorden. Genetiska, kemiska och morfologiska data (längd och vikt) samlades in i syfte att bestämma vilka populationer de härstammade ifrån. Fångster av sill är så gott som alltid av blandat ursprung eftersom individer bara samlas i de populationer de stammar ifrån vid den tid på året då det är dags för parning (lek). I den här uppsatsen klassificerar jag juvenilerna till tre regioner i vilka populationerna ingår, genom att jämföra de data som samlats in från juvenilerna med motsvarande data i en stor databas över populationer i Nordsjön, Skagerrak, Kattegat och Östersjön samt med ytterligare en population, Risør, som inte ingår i denna databas. Data om populationerna kommer från samples och de sanna populationsparametrarna (dvs.

"Tyst för fan" En studie om Jantelagens existens och kontroll

AbstractAre we always aware of our actions and the affect they have on our environment? With this study we are exploring a phenomenon, called Jantelagen, which have affected the Swedish society for a long time. It is a phenomenon that where brought to life officially in the 1930?s by an author called Aksel Sandemose. We want to know if Jantelagen still exist in the society or if it has faded to the degree that it is no longer in use.

Geografisk presentation i ett mikrosimuleringsverktyg

Samhällsgeografiskt miljöcentrum (Spatial Modelling Centre), SMC, bedriver forskning och utveckling av datorbaserade geografiska modeller. Syftet är att stödja uppdragsgivaren, Kulturgeografiska institutionen vid Umeå universitet, och andra med dessa verktyg. Med hjälp av den egenutvecklade modellen SVERIGE kan man göra experiment i full skala med en syntetisk population som motsvarar hela Sveriges befolkning. Detta examensarbetes syfte var att ta fram möjlighet till geografisk presentation för den grafiska klienten till SVERIGE. Detta som ett komplement till de tabeller som genereras vid körningar av modellen.

10 000 nya invånare till Luleå! : En studie om en kommuns platsmarknadsföring i sociala medier

Today, nine out of ten municipalities are active on social media and it has become increasingly popular among municipalities that make use of placemarketing to promote their particular region. A problem that is raised in this study is that the population of the municipalities in northern Sweden often is in decline. The purpose of this study is to investigate how a democratic-controlled organization such as Luleå Municipality uses the social media Facebook in its placemarketing, to highlight a place of scale and to attract new residents and stakeholders to move to or visit the city. In order to answer the purpose I have with the help of a critical discourse analysis examined how Luleå Municipality using social media Facebook in their marketing of Luleå as a place. The results were then analyzed using theories of placemarketing, Norrland and the market-oriented municipality.

Jordbruk och mjölkproduktion med kor i Etiopien :

Ethiopia is the country with most livestock per capita on the continent of Africa. There are 34.5 million cattle that are used for drought, meat- and milkproduction and 85% of the population rely on agriculture for their survival in some way. Milk is produced in four main systems, through pastoralism in the lowlands, in mixed crop-livestock systems in the highlands, in and near big cities with only one or two cows, and in intensive farming systems. There are 17 cattle breeds in Ethiopia and some of them are more suitable for milk production than others. Several environmental and economic problems arise from livestock holding in the country, for example overgrazing, low production due to feed shortage, low quality of the avaible feed and non-existing breeding programs.

Den Kontroversiella Agendan: Om Sveriges och det internationella samfundets utvecklingssamarbete för sexuell och reproduktiv hälsa och rättigheter

The aim of this thesis is to explain what actions Sweden and the international communities have been taking in terms of sexual and reproductive health and rights (SRHR) in order to realize the Programme of Action from the International Conference on Population and Development in Cairo 1994. In a theoretical perspective, donor countries and multilateral organizations are seen as interacting actors involved in global development cooperation. Through applying a human rights approach I will show shortages in terms of supplies to contraception, international agreement on the issue of safe abortions and a new era that comes with new rules for aid and development cooperation. In addition, for human rights to be realized there is the feature of accountability. Without accountability, SRHR cannot be fully respected, guaranteed and protected.

Validering av Casmo-5M / Simulate-3

The objective of this M. Eng. Diploma work was to validate the new version, CASMO-5M, and compare the results with CASMO-4E, by using the same input in both programs. The tasks that were included in this work was to compare TIP-measures, k-effective curves (warm), k-effective curves (cold), the effect of void on k-effective, the isothermal temperature coefficient (ITC), the moderator temperature coefficient (MTC), damping ratio calculations, internal effect in a fuel bundle of a BA-rod, the speed of BA-out burn, impact of xenon, falling control rod, margins and isotopes.The TIP-measures showed that the differences were small for all reactors, at most, 6% nodal improvement by C5M (Casmo-5M) for Oskarshamn 3. The warm measurements of k-effective showed that C5M had a higher value for all cycles of Oskarshamn 1, 2 and 3 in comparison to C4E (Casmo-4E).

Bankväsendets relationsmarknadsföring riktat mot den yngre generationen, sett utifrån ett kundperspektiv

Syfte:Att undersöka hur den yngre generationen (19-29 år) upplever att bankerna arbetar med marknadsföring gentemot dem. Vidare är vårt syfte att undersöka hur den yngre generationen upplever deras relation till bankväsendet, och vad de anser är viktigt i valet av bank.Forskningsfråga:Hur upplever den yngre generationen att bankväsendet arbetar med relationsmarknadsföring gentemot dem?Hur beskriver den yngre generationen sin relation till bankväsendet?Vad anser den yngre generationen är viktigt i valet av bank?Metod:Att utifrån ett deduktivt vetenskapligt synsätt genomföra en enkätundersökning på en population som representerar en yngre generation samt att genom observation klarlägga och analysera bankväsendets användning av sociala medier, webbsidor och kundbemötande.Slutsats:Bankväsendet ägnar sig inte åt ett relationsmarknadsföringsarbete som den yngre generationen upplever som tillfredsställande och tillräcklig. Undersökningen visar att den yngre generationen beskriver sin relation till bankväsendet som relativt avlägsen. Den yngre generationen är också relativt eniga om att det allra viktigaste vid bankval är att känslan av förtroende för personalen och upplevelsen av att banken kan se människan som en enskild individ. .

Dom kallar det Lean? En studie om Lean i sjukvården och dess påverkan på den professionelle läkarens medicinska beslutsfattande

The purpose of this media scientific study is to contribute to a better understanding about how blind people?s empowerment and participation may affect their role in the digital society.Earlier international studies in this area have shown that blind people not only need more knowledge then the seeing population about the computer, but also about the technology behind their tools for using Internet. The results from these studies have also shown that Internet increases the blind people?s independents and that those who use Internet feel more involved in the society.A qualitative method was chosen to study the three most common categories from the earlier studies: knowledge of technology, empowerment and participation. Are there differences in the results compared to our study in Sweden 2014?Interviews with eight blind, experienced computer users have shown that knowledge of technology is essential for their use of Internet and that the Internet increases their empowerment and their participation.

Att främja goda matvanor ? en intervjustudie med förskolepersonal i fokus

Bakgrund: Folkhälsan i Sverige beror till viss del på befolkningens matvanor. Matvanor grundläggs i de tidiga åren vilket ger den offentliga miljön, exempelvis förskolor, stora möjligheter att skapa goda förutsättningar för barnens matvanor. På såväl global som nationell nivå finns flera styrdokument som berör barns matvanor och hälsa. Det debatteras ofta vilka risker befolkningens matvanor innebär. Vi ville öka förståelsen för matens möjligheter genom ett salutogent perspektiv.
