The goal of the thesis work was to give Softronic AB, a management and IT consulting company, an overview of strengths and weaknesses of the four content management systems Magento CE 1.6.2, Episerver Commerce 1 R2 SP1, Wipcore eNOVA 5.3 and Umbraco CMS, as platforms for ecommerce. The evaluation was to be made from a marketing perspective as well as from a user and in-house developer's perspective. Additionally, the goal was to provide an overview of how certain functionality from a current project could be implemented on the Magento CE platform. To be able to evaluate the platforms, a study of current evaluation and comparison models was performed. This resulted in the choice of the framework Domain-specific Architecture Comparison Model. A comparison framework was derived and defined from this model, and applied on the platforms. The choice of what was to be measured, and how, was determined from literature studies of the e-commerce domain, as well as studies of current e-commerce platforms. The demonstration of the capabilities of the Magento platform was solved by creating a new Magento store instance, implementing two components from a reference project, as well as parts of the graphical user interface, and deploying the solution on a cloud server. The evaluation resulted in a description of the platforms' strengths and weaknesses, and a table showing the properties of the platforms. The evaluation indicated that the platforms Magento CE and Episerver Commerce were the strongest when it came to functionality and market readiness. Wipcore eNOVA and Umbraco CMS's strongest side was performance efficiency, while none of the platforms were assessed as particularly strong in terms of maintainability. / Målet med examensarbetet var att ge Softronic AB, ett konsultbolag inom IT och management, en översikt över vilka styrkor och svagheter de fyra CMS-plattformarna Magento CE 1.6.2, Episerver Commerce 1 R2 SP1, Wipcore eNOVA 5.3 samt Umbraco CMS hade som e-handelssystem. Utvärderingen skulle ske dels utifrån ett marknads- och kundperspektiv men också från ett utvecklarperspektiv inifrån företaget. Målet var också att ge en översikt över hur vissa funktioner för ett befintligt projekt kunde implementeras på plattformen Magento CE. För att utvärdera plattformarna gjordes en litteraturstudie över befintliga jämförelsemodeller, vilket resulterade i valet av ramverket Domain-specific Software Architecture Comparison Model. Ett jämförelseramverk definierades utifrån modellen och applicerades på plattformarna. Vad som skulle utvärderas och hur det skulle mätas bestämdes utifrån litteraturstudier av affärsområdet samt studier av befintliga e-handelsplattformar. Demonstrationen av Magentoplattformen löstes genom att sätta upp en Magento-installation på en molnserver och implementera två komponenter samt delar av det grafiska användargränssnittet för ett referensprojekt. Evalueringen resulterade i en beskrivning över plattformarnas styrkor och svagheter samt en överskådlig tabell som kan vara till nytta för Softronic i inledningsskedet av framtida ehandelsprojekt. Evalueringen visar att plattformarna Magento CE och Episerver Commerce är starkast när det gäller funktionalitet och att snabbt få ut en lösning på marknaden. Wipcore eNOVA och Umbraco CMS har styrkor när det gäller prestanda, medan ingen av plattformarna bedömdes vara starka när det gäller egenskaper som underlättar underhåll och utveckling.

In a world focusing increasingly on climate change, businesses face multiple risks if they do not adapt. Therefore, creating long term business strategies focused on climate change are essential not only to navigate risks, but also to be able to capitalize on potential opportunities. Additionally, investors as well as consumers demand businesses to make changes as well as openly communicate their long term intentions. However, due to the complexity of the strategies developed, it is difficult for consumers, investors, and even the companies themselves to obtain an overview. Therefore, this article aims at developing a climate strategy comparison framework to aid in assessing and comparing the strategies, as well as improving the transparency. The framework consist of the Target, Achievement and Action Dimension.

Nous avons développé un système intégré permettant l'acquisition simultanée de la forme 3D ainsi que de la réflectance des surfaces des objets scannés. Nous appelons ce système un scanner 3D multispectral du fait qu’il combine, dans un couple stéréoscopique, une caméra multispectrale et un système projecteur de lumière structurée. Nous voyons plusieurs possibilités d’application pour un tel système mais nous mettons en avant des applications dans le domaine de l’archivage et la diffusion numériques des objets du patrimoine. Dans le manuscrit, nous présentons d’abord ce système ainsi que tous les calibrages et traitements nécessaires à sa mise en oeuvre. Ensuite, une fois que le système est fonctionnel, les données qui en sont générées sont riches d’informations, hétérogènes (maillage + réflectances, etc.) et surtout occupent beaucoup de place. Ce fait rend problématiques le stockage et la transmission, notamment pour des applications en ligne de type musée virtuel. Pour cette raison, nous étudions les différentes possibilités de représentation et de codage des données acquises par ce système pour en adopter la plus pertinente. Puis nous examinons les stratégies les plus appropriées à la compression de telles données, sans toutefois perdre la généralité sur d’autres données (type satellitaire). Nous réalisons un benchmark des stratégies de compression en proposant un cadre d’évaluation et des améliorations sur les stratégies classiques existantes. Cette première étude nous permettra de proposer une approche adaptative qui se révélera plus efficace pour la compression et notamment dans le cadre de la stratégie que nous appelons Full-3D. / We have developed an integrated system permitting the simultaneous acquisition of the 3D shape and the spectral spectral reflectance of scanned object surfaces. We call this system a 3D multispectral scanner because it combines within a stereopair, a multispectral video camera and a structured light projector. We see several application possibilities for a such acquisition system but we want to highlight applications in the field of digital archiving and broadcasting for heritage objects. In the manuscript we first introduce the acquisition system and its necessary calibrations and treatments needed for his use. Then, once the acquisition system is functional, data that are generated are rich in information, heterogeneous (mesh + reflectance, etc.) and in particular require lots of memory space. This fact makes data storage and transmission problematic, especially for applications like on line virtual museum. For this reason we study the different possibilities of representation and coding of data acquired by this system to adopt the most appropriate one. Then we examinate the most appropriate strategies to compress such data, without lost the generality on other data (satellite type). We perform a benchmark of compression strategies by providing an evaluation framework and improvements on existing conventional strategies. This first study will allow us to propose an adaptive approach that will be most effective for compression and particularly in the context of the compression strategy that we call Full-3D.
