The aim of this work is to create an extension for rendering engine CSSBox. This extension will implement Document Object Model interface for the Client-Side JavaScript. The first part of this thesis describes the CSSBox project, the current state of JavaScript engines, Document Object Model used in web browsers and the final design based on Adapter and Abstract Factory patterns. The rest of the text describes implementation issues with the W3C DOM specification and compares the speed of this extension with web browsers.

Diese Arbeit präsentiert 9 Entwurfsmuster in einer Darstellung durch das Compartment Role Object Model(CROM). Dabei wird dessen graphische Notation für rollenbasierte Modelle mit verschiedenen Möglichkeiten zur Darstellung von Bedingungen des Entwurfsmusters benutzt. Über eine Evaluationsoll ermittelt werden, ob das CROM dazu geeignet ist, die Bedingungen von Entwurfsmustern verständlich und schnell erfassbar darzustellen. Dabei soll die graphische Dokumentation dieser helfen. Das kann positive E ekte auf die Entwicklung von Software haben, wie bessere Codequalität, verkürzte Entwicklungszeiten und die Vereinfachung der Kommunikation zwischen Entwicklern.

This diploma thesis describes the implementation of a 3D model of two objects using laser scanning. This paper deals with the accuracy evaluation of several data interpretation. The first two methods are the outputs of the results from the FARO SCENE program and other interpretations are the outputs from the TRIMBLE REAL WORKS program. To assess accuracy and veracity, the exact test field of points previously built in the AdMas complex was used. The result of the project is a georeferenced 3D model of two objects with the surrounding environment.

Under de senaste decennierna har webben utvecklats allt mer, och är idag en stor del av människors vardag. Det finns idag över 1,8 miljarder webbplatser i bruk, och över 97% av dessaanvänder sig av JavaScript som programmeringsspråk för klientsidan. Människans koncentrationsförmåga har också minskat genom åren, och det ställs idag allt högre krav på snabba responstider på webben. Användarupplevelsen är också väldigt viktig för att en webbplats ska lyckas med sitt ändamål. Vi har i vår studie valt att undersöka och jämföra prestandan i JavaScript-ramverken Svelte och Vue, där vi ville studera eventuella prestandaskillnader med särskild fokus på responstider. Vi ville även undersöka om eventuella prestandaskillnader kunde upplevas av användarna vid olika typer av manipulationer av DOMen, såsom exempelvis tillägg och borttagning av HTML-elementet <div> i både större och mindre skala, och således påverka användarupplevelsen. Vi utvecklade två stycken single-page-applikationer som använder sig utav JavaScript, där den ena använder sig av Vue och den andra utav Svelte som frontend-ramverk, för att sedan utföra prestandatester på bägge webbplatserna. Därefter lät vi en grupp användare testa webbplatserna för att sedan svara på en enkät, där enkätfrågorna fokuserade på hur de upplevde prestandan ochom de kunde märka någon skillnad mellan applikationerna. Datainsamlingen för att kunna besvara de andra parametrarna för ramverken som denna studieämnade att undersöka, som går under användbarhet, skedde genom att skicka ut en enkät där vi lät både professionella frontend-utvecklare samt utvecklare på hobbynivå med erfarenhet av både Svelte och Vue besvara ett antal frågor om användbarhet. Slutsatsen av studien mynnar ut i att prestandaskillnader mellan ramverken i våra single-page-applikationer existerar, och kan i vissa fall också märkas av användarna. Om utvecklarna själva får bestämma vilket ramverk de föredrar väljer de professionella utvecklarna att arbeta med Vue och hobbyutvecklarna Svelte. För den officiella dokumentationen tenderade båda respondentgrupperna att föredra Vue över Svelte.

Este trabalho estuda o problema da construção de sistemas orientados a objetos com características adaptativas, tendo como principal objetivo simplificar o processo de construção. Para isso o trabalho utiliza como base teórica a Tecnologia Adaptativa e sua aplicação em diversos formalismos. O Modelo Adaptativo de Objetos foi utilizado como base de comparação de soluções para a construção de sistemas adaptativos. Nesta pesquisa são apresentadas aplicações e uma proposição para a construção e modelagem de sistemas adaptativos, através da extensão do conceito de objetos com características da tecnologia adaptativa. Através deste estudo avaliou-se o impacto da aplicação do dispositivo adaptativo em um formalismo com tipo. Os resultados obtidos no presente trabalho demonstram que a tecnologia adaptativa é propícia para linguagens orientadas a objetos e que os diagramas UML são capazes, com pequenas extensões, de representar o comportamento adaptativo adequadamente. / This study addresses the issue of implementing object-oriented software with adaptive characteristics, having as primary purpose simplify the implementing process. The key theoretical basis consisted in adaptive technology and its application in various formalisms. Adaptive Object Model has been taken as comparison basis to solutions to implement adaptive systems. This study describes applications and a proposition to implement and model adaptive systems, through the extension of object concept with adaptive technology characteristics. It also evaluates the impact of applying adaptive devices in formalism with types. The results obtained demonstrate that adaptive technology is suitable for object-oriented languages and that UML diagrams are capable of presenting adaptive behavior appropriately with a small number of extensions.

Efficiency and innovative problem solving are contradictory requirements for productdevelopment (PD), and both requirements must be satisfied in companies that strive to remainor to become competitive. Efficiency is strongly related to ”doing things right”, whereasinnovative problem solving and creativity is focused on ”doing the right things”.Engineering design, which is a sub-process within PD, can be viewed as problem solving or adecision-making process. New technologies in computer science and new software tools openthe way to new approaches for the solution of mechanical problems. Product datamanagement (PDM) technology and tools can enable concurrent engineering (CE) bymanaging the formal product data, the relations between the individual data objects, and theirrelation to the PD process. Many engineering activities deal with the relation betweenbehavior and shape. Modern CAD systems are highly productive tools for conceptembodiment and detailing. The finite element (FE) method is a general tool used to study thephysical behavior of objects with arbitrary shapes. Since a modern CAD technology enablesdesign modification and change, it can support the innovative dimension of engineering aswell as the verification of physical properties and behavior. Concepts and detailed solutionshave traditionally been evaluated and verified with physical testing. Numerical modeling andsimulation is in many cases a far more time efficient method than testing to verify theproperties of an artifact. Numerical modeling can also support the innovative dimension ofproblem solving by enabling parameter studies and observations of real and syntheticbehavior. Simulation-driven design is defined as a design process where decisions related tothe behavior and performance of the artifact are significantly supported by computer-basedproduct modeling and simulation.A framework for product modeling, that is based on a modern CAD system with fullyintegrated FE modeling and simulation functionality provides the engineer with tools capableof supporting a number of engineering steps in all life-cycle phases of a product. Such aconceptual framework, that is based on a moderately coupled approach to integratecommercial PDM, CAD, and FE software, is presented. An object model and a supportingmodular modeling methodology are also presented. Two industrial cases are used to illustratethe possibilities and some of the opportunities given by simulation-driven design with thepresented methodology and framework. / QC 20100810

The statistical evaluation of molecular imaging approaches for detecting, diagnosing, and monitoring molecular response to treatment are required prior to their adoption. The assessment of fluorescence-enhanced optical imaging is particularly challenging since neither instrument nor agent has been established. Small animal imaging does not address the depth of penetration issues adequately and the risk of administering molecular optical imaging agents into patients remains unknown. Herein, we focus upon the development of a framework for OAIQ which includes a lumpy-object model to simulate natural anatomical tissue structure as well as the non-specific distribution of fluorescent contrast agents. This work is required for adoption of fluorescence-enhanced optical imaging in the clinic. Herein, the imaging system is simulated by the diffusion approximation of the time-dependent radiative transfer equation, which describes near infra-red light propagation through clinically relevant volumes. We predict the time-dependent light propagation within a 200 cc breast interrogated with 25 points of excitation illumination and 128 points of fluorescent light collection. We simulate the fluorescence generation from Cardio-Green at tissue target concentrations of 1, 0.5, and 0.25 µM with backgrounds containing 0.01 µM. The fluorescence boundary measurements for 1 cc spherical targets simulated within lumpy backgrounds of (i) endogenous optical properties (absorption and scattering), as well as (ii) exogenous fluorophore crosssection are generated with lump strength varying up to 100% of the average background. The imaging data are then used to validate a PMBF/CONTN tomographic reconstruction algorithm. Our results show that the image recovery is sensitive to the heterogeneous background structures. Further analysis on the imaging data by a Hotelling observer affirms that the detection capability of the imaging system is adversely affected by the presence of heterogeneous background structures. The above issue is also addressed using the human-observer studies wherein multiple cases of randomly located targets superimposed on random heterogeneous backgrounds are used in a “double-blind” situation. The results of this study show consistency with the outcome of above mentioned analyses. Finally, the Hotelling observer’s analysis is used to demonstrate (i) the inverse correlation between detectability and target depth, and (ii) the plateauing of detectability with improved excitation light rejection.
