Den klassiska approachen till navigering innefattar att agenten håller en intern representativ modell av omgivningen. Denna approach har emellertid många nackdelar, speciellt för dynamiska miljöer. En modernare approach är att förlita sig på den faktiska omgivningen istället för en modell av denna. Detta arbete presenterar en undersökning av navigeringsproblemet och hur väl det löses av agenter vars kontrollmekanismer utgörs artificiella neurala nätverk. Tillförlitligheten hos de två neurala arkitekturerna Extended sequential cascaded network och Self-organized recurrent network bestäms genom experiment.

This study aims to find out what relationship high school students have to social networks at the Internet. This has been done by focusing on norms/standards that adolescents can feel under stress to achieve, through stressing themselves by social networks in a way that is consistent with the norms.

The existence of social networks on the Internet is today seen as broad, and the number of users of the network is increasing. There seems to be many reasons to which people are using the social networks. Within the network, users can for various reasons create groups with different objectives. One of the reasons is that groups are created in order to influence a company. With a perceived feeling that companies handle the problem differently, we assume the source is the uncertainty about what the groups really are.

Abstract The increased focus on social capital theory has made its way into labour economics. This has led to the creation of a vast literature about the use of networks and informal search methods in the labour-market, a literature that to some extent also deals with immigrants search behaviour and their relatively high unemployment rate. Characteristic for the literature in the area is the lack of analysis of actual networks. Which types of contacts do these networks contain; how are the networks used in the labour-market; and which type of network generates a high amount of social capital. These questions are important for the general understanding of how social capital functions, within the labour-market, but also for the understanding of how immigrants use their networks in order to find themselves jobs.

Species that have a high degree of specialization and poor dispersal ability can be more prone to extinction than more generalist species and good dispersers. How these species traits affect the viability of populations is dependent on landscape factors,such as isolation and connectivity. Additionally, interactions between species (e.g. symbiosis), and how these interactions vary spatially and temporally can have a large impact on populations. When the range and habitat areas of a species continuously decrease, management strategies are often needed if the species shall be able to survive.

Human presence has always influenced the surrounding areas, the forest as well. Structure and species composition have changed during human land use. Knowledge regarding these changes should be of great interest for conservation and forestry. We have analyzed human impact on the tree species composition on five study sites during 2000 years in Ångermanland, Sweden. More specifically the change in tree species composition in percentage amongst alder, birch, spruce and pine over time.
