<p>Gör emotioner en spelupplevelse bättre? Jämfört med äldre narrativa medier såsom film och skönlitteratur är spelbranschen ung och anses på många sätt vara mindre sofistikerad ifråga om emotionellt djup. Spel har, till skillnad från film där emotioner väcks genom empati med karaktärer, ofta ett förstapersonsperspektiv vilket gör det lättare att förbättra spelupplevelsen genom att väcka emotioner hos spelaren direkt. I detta arbete syftar emotioner på de av djupare slag som traditionellt sett varit sällsynta inom spel då dessa ofta är primärt gameplaydrivna. Verktyg för att förändra ett spel till att bättre väcka emotioner existerar i form av sätt att skriva vilket gör karaktärer, handling och dialograder djupare och mer intressanta. För att testa om detta verkligen gör en spelupplevelse bättre framställs två versioner av ett spel, en version med grundläggande dialog och en där dessa verktyg applicerats. I övrigt är spelen identiska. Därefter testas spelen på en försöksgrupp och spelupplevelsen mäts. En analys av mätningarna visar att försökspersonerna över lag hade en bättre spelupplevelse av spelet som hade bearbetats med hjälp av verktygen jämfört med gruppen som fick spela den enkla versionen.</p>

<p>The research objective of this thesis is to identify corporate strategies and strategic decisions in the digital printing business and to analyze how these have evolved due to the introduction of digital printing. This thesis comprises three separate studies, all based on qualitative case methodology. The first study is focused on digital printing houses and how their business strategies have changed due to their investment in digital printing production equipment. The second study concentrates on customers in the digital printing value system and how they experience the value they get from purchasing digitally printed products. In the third study, it is analyzed how a successful producer–customer relationship can create value for both parts in a dynamic and changing business environment.</p><p>The results indicate that vertical integration among digital printing houses is a valid strategy for overcoming problems related to digital printing, such as not being able to acquire orders suitable for digital printing. The main reason among customers to start using digital printing is the option of ordering short print runs which reduces stock keeping and discarded volumes. This application is the customers’ most important perceived value. The use of more complex applications, such as variable data printing, is very modest, although many respondents say that they either want to start using customization in their print production or already have received some value from simpler variable data printing applications (e.g. addressing or changing logos and names).</p><p>The competitive environment in the printing industry is becoming increasingly dynamic and the printing industry is today influenced by a heterogeneous group of competitors and it is therefore important, for printing houses, to engage in hypercompetitive-like behavior. Working with speed, surprise, superior customer satisfaction and continually trying to shift the rules of the industry in the company’s favor, is a strategy to maintain business viability and competitiveness. As a complement to the cost and quality focus, timing and know-how are becoming even more important in the industry when a company wants to satisfy customer needs.</p><p>The conclusion is that digital printing is used effectively and successfully when the main purpose is not to print. By striving towards non-printed solutions, digital printing becomes a natural output method when printed material is needed, since it is possible for the customers to order exactly what they want, when they want it, without any need for stock keeping. Vertical integration has helped digital printing houses acquire appropriate input for their printing presses. Horizontal integration into additional output channels, such as electronic publishing, is a natural development in the industry and provides support for the digital printing business.</p>

<p>This thesis gives an introduction to a currently active area in the cross-section between theoretical computer science and theoretical physics. In the last ten years it has been suggested that critical behaviour, usually seen in models from condensed matter physics, may be responsible for the intractability of NP complete computation problems. This would suggest a very deep connection between the two fields on the most fundamental level. How deep this connection really is is subject to ongoing research as well as the topic of this thesis. Some of the conjectrues from the physics community regarding computational hardness in certain problem classes has turned out to be wrong or misinterpreted but the gained interest in both fields has promising potiential in moving the research frontier forward.</p><p> The material presented in this thesis is the result of nearly two years work in trying to clearify how the results from physics can be interpreted in the language of actuall computation problems.</p> / <p>Denna avhandling ger en introduktion till ett mycket aktivt forskningsområde i gränslandet mellan teortisk datalogi och teoretisk fysik. Under de senaste tio åren har det framkommit forskningsresultat som pekar på att kritiska fenomen, vanligen hemmahörande i modeller från teoretisk materialfysik, kan vara nyckeln till att förstå varför NP fullständiga problem är så svåra att lösa. Detta skulle innebära en mycket djup och fundamental koppling mellan de bägge områdena. Hur djup denna koppling verkligen är är temat i mycket av pågående forskning såväl som ämnet för denna avhandling. Vissa förutsägelser från den teoretiska fysiken har visat sig felaktiga eller feltolkade men det ökade intresset för dylika frågor inom bägge forskningområden ger hopp om att tillsammans kunna flytta from forskningsfronten.</p>

<p>This licentiate thesis highlights some topics on modular modelling for dynamical simulation with application to fluid systems. The results are based on experience from the development of the fuel cell component simulation environment NFCCPP. The general application is cross-enterprise simulation of technical systems. There are four main topics: component definition including selection of interfaces, lumped modelling of fluid components, the use of dynamical equations to reduce simulation time in large systems and methods of to protect the intellectual property (IP) of a component.</p><p>An overview of different dynamical fluid simulation tools such as HOPSAN, MATLAB/Simulink and Easy5 is presented. Special focus is on interfaces, where different approaches for representing interfaces are presented using an illustrative example. Selecting interfaces is however not a separated task from how to set up and solve the underlying equations, which also is shown. Equations to model a lumped component are derived, to get a mathematical background to what problems there are to solve. These equations are derived especially to be applicable in block model software simulation tools such as MATLAB/Simulink. The equations are also compared with the bond-graph approach of representing dynamical systems. A twinscrew compressor is modelled in MATLAB/Simulink as an implementation of these equations. A method to decrease the simulation time in dynamical fluid system is also presented. The technique is to add virtual mass in the force equation to get a slower acceleration of the fluid. Using this slower response, it is possible to use larger time-steps when integrating the equations and thus the total simulation time can be reduced. The error introduced using this method is a modelling error in the time domain, and it is comparable with using unit transmission lines (UTL:s), as does HOPSAN.</p><p>The protection of the intellectual property (IP) of a component model is presented. The concept of clamping is thoroughly explained, as it often is overlooked in conventional IPprotection. Three concepts for code protection are presented: “Centralised simulation with remote user control”, “Localised simulation with simulation-time model usage control” and “Parallel distributed simulation”. The NFCCPP implementation of the concept “Localised simulation with simulation-time model usage control” is presented in more detail.</p>

<p>OpenModelica is a complete environment for developing and simulatingModelica models based on free software. It is promoted and developed bythe OpenModelica Consortium. This thesis details a method for describingand consequently displaying visualizations of Modelica models in OMNote-book, an application in the OpenModelica suite where models can be writtenand simulated in a document mixed with text, images and plots. Two dif-ferent approaches are discussed; one based on Modelica annotations and onebased on creating a simple object hierarchy which can be connected to exist-ing models. Trial implementations are done which make it possible to discardthe annotation approach, and show that an object based solution is the onebest suited for a complete implementation. It is expanded into a working 3Dvisualization solution, embedded in OMNotebook.</p>

<p>VizzAnalyzer is stand-alone tool for analyzing and visualizing the structures of largesoftware systems. Currently, it only supports to analyze Java and UML programs.Considering about the widen acceptance of C/C++ program languages, we think it isnecessary to create this C/C++ Front-End to enable VizzAnalyzer to analyzer C/C++programs.To create the C/C++ Front-End, we need to get C/C++ Front-End Meta-Model first.For doing this, we selected Eclipse CDT as the compiler for C/C++ source files.Secondly, we create a mapping between C/C++ Front-End Meta-Model to Common-Meta-Model. The mapping result will be used by VizzAnalyzer to do further analysiswork.This Bachelor thesis documents relative theory to this C/C++ Front-End and how ithas been developed and implemented.</p>

The current Internet design is based on a number of principles and paradigms. A central theme of these is that the interior of the network should provide a very simple but generic (and optimized) service, namely best-effort packet forwarding. For the users, a consequence of this design is that performance properties and the behavior of the network can typically only be determined by performing probing-based measurements. Probing means that special packets are injected into the network by one computer while another one receives and collects statistics about those packets. Using this statistical information, it is possible to make inferences about the network and its characteristics. One important characteristic is the bandwidth that is available on the network path between two computers in the Internet. When communicating with each other, the computers should not persistently send data at a higher rate than the available bandwidth since that will eventually lead to packet loss due to the overload. This thesis considers the problem of measuring the available bandwidth of a network path using probing-based methods. To that end, we propose a new method called TOPP. It is designed to probe the network non-intrusively so that the measurements do not jeopardize the stability of the network. In addition to estimating the available bandwidth, TOPP also provides an estimate of the link capacity of the link that limits the available bandwidth. In the second part of this thesis we propose and evaluate different models for trace-driven network path emulation. We also investigate how to probe a network path for the purpose of trace-driven emulation. We show that relatively simple trace-driven models work well for non-responsive UDP-based flows. However, for adaptive TCP flows, these simple models do not seem to perform well. We also find that for the trace-driven models studied, strongly bursty probing schemes (which includes probing by TCP) have undesirable properties and should be avoided.
