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.

Den situerade ansatsen inom artificiell intelligens har i tidigare experiment visat på stora möjligheter vid utvecklingen av enkla beteenden. Ansatsens framgångar är dock inte lika tydliga när det kommer till utvecklingen av mer komplexa beteenden som i högre grad påminner om de experiment som gjorts inom traditionell artificiell intelligens. I studien utvecklas en agent med ett ?Extended sequential cascaded network? som kontrollarkitektur för att lösa en uppgift som kräver ett ?räkneliknande beteende?. Utvecklingen av nätverket grundas på en situerad syn på kognition, däribland att designern i så liten grad som möjligt skall styra utvecklingen.

Detta arbete tar upp och diskuterar det eventuella användandet av representationer i en autonom robot kontrollerad av ett extended sequential neural network (ESCN). Diskussionen utgår från en tidigare distinktion, framförd av bl.a. Bickhard och Terveen (1995), mellan traditionella representationer, som förespråkas av kognitivismen, och interaktiva representationer, som förespråkas av många företrädare för en mer förkroppsligad och situerad syn på kognition. Resultatet i detta arbete visar att det är möjligt, med hänvisning till robotens interna tillstånd, att påstå att roboten inte använder sig av representationer i någon traditionell bemärkelse. Resultatet visar vidare att det är möjligt att hävda att roboten använder sig av interaktiva representationer.

The purpose of this thesis is to examine value creation in networks. Based on a case study of Livebookings Network, an online booking service. This thesis has an explorative nature. As a theoretical framework we use theories on value and network dynamics. By combining these theories we develop an operationalized framework that we use to analyze our empirical findings.

Research has shown that our numbers of choices are constantly increasing. In this paper, we investigate the choice-making process further with regard to satisfaction, recommendation propensity, confidence, and preference. The study focuses on two fitness clubs where product information is provided sequential to the participant. We examine if consumers who maintain their choice tend to be more satisfied with their choice and more willing to recommend the choice to a friend. If they are, why is this? We found that the participants who changed their choice claimed to be less satisfied and had less propensity to recommend the choice to a friend.

Facial expressions are a part of our body language that helps us to clarify the verbal communication between humans. We use our facial expressions every day, both consciously and unconsciously, to express emotions and attitudes depending on the situation. The hypothesis of the study is: Given a facial expression, how well can Microsoft Kinect, as an input method, determine a person?s feelings with the two algorithms Naive Bayes and Sequential Minimal Optimization? The feelings are limited to happy, sad, surprised and disgusted. With the help of Kinect, a person?s facial data, both coordinates of the face and parameterized data, were saved and used for machine learning.

This thesis discusses various approaches that venture capitalists have when evaluating investment prospects. The thesis is a case study of the business angel network Firm Factory Network. The empirical material is based on an extensive interview with Firm Factory CEO Daniel Kaplan. Our conclusion is that Firm Factory Network uses both informal and formal methods when they evaluate interesting prospects..

This examination work is about implementation of Cisco Systems Network Admission Control (NAC) within a leading IT-company in region of Jönköping. NAC is a technique that is used for securing the internal network from the inside. NAC can verify that the client who connects to the network has the latest antivirus updates and latest operative system hotfixes. Clients who don?t meet the criteria can be placed in quarantine VLAN where they only have access to the update servers.

The purpose of this master`s thesis is to examine how the contemporary changes in society display itself in the network Ecumenical Forum of European Christian Women EFECW and to increase the understanding of networks. My main questions are: What does the networks structure look like? What does the networks relationships look like? How is identity created in the network and what types of identities is created? The objectives are reached by using two methods, qualitative inquiries and document analysis. The inquiries were carried out to nine members in the network of different countries. The theoretical framework of the thesis is Manuel Castells theories of the network society, and the study is also placed in context by a presentation of previous research on the field.

The purpose of this thesis is to explore the co-creation process and how value is created based on a service orientation using a network perspective. The thesis is studied from a social-constructionist philosophy, using a qualitative approach of data collection and the theoretical framework includes network theories, theories of service-orientation and co-creation. We have conducted semi-structured interviews with a small firm and its network, which consists of a customer, a supplier and a partner. We found that Håkansson?s ARA framework combined with Ballantyne and Varey?s triangulation of value-creating activities help to acquire an understanding of the actors? bonds, the resources? ties and the activity links that exist in a network.

The aim of this report is to examine the possibilities to use network theories to perform vulnerability analysis on complex networks. The scoop of this work is also to improve the possibilities to chart, analyze and present the vulnerability in a power grid. In this report it has been, using power outage statistics, possible to verify, that network theories can be used to evaluate the vulnerability of an infrastructure network. However further studies to establish values on how vulnerable a network is are needed..

In this thesis a rural network in Norrbotten, Sweden, has been to designed and planned with the purpose of improving distribution reliability by exchanging existing overhead lines with underground cables. General network design considerations are discussed as well as the ones for the specific low voltage grid. During the design phase the maximum power of domestic consumers has been estimated using Velander?s method. Currents, voltage drop and impedance of the network have been calculated and fuse operation and selectivity has been considered.

The network with its virtual business structure challenge the established vertical business structure. Part of the network theory that has developed focuses on relationships that forms B2Bnetworks. One way to create a B2B-network is for independent businesses to form a organization promoting co-operation. For co-operation to be successful it requires well thought-out actions, but a lack of how these actions are implemented have been noticed. This study explores how encouragement of co-operation can be done practically.

Energy losses are an essential part of a power grid company?s costs. From anenvironmental and economic perspective, it is important to reduce these costs. Toknow where efforts should be deployed, it is important to have good knowledge ofwhere in the network losses are situated. When creating network tariffs, there is alsonecessary to have a correct distribution such that the network customers that use acertain part of the network, only pays for the network losses in this area.
