682	Collapsible Home : Celebrate life again / Hopfällbara Hem Kalantari, Meisam January 2016 (has links) There has been significant increase in the occurrence of earthquakes and other disasters around the world recently. With record-breaking storms and natural disasters destroying different parts of the world, many people have to deal with the repercussions of the aftermaths; and homelessness is one of the facts of such incidence. This master thesis is aimed at creating living solution for the victims of earthquakes and other kind of disasters; natural or human-made (war), providing accommodation for homeless people after an earthquake or a housing alternative for refugees. The design of the collapsible home is basically a new concept of emergency hut for accommodating people in emergency after the event of disaster with easy assembling and quick installation feature. Considering the situation of homeless people after catastrophic disasters who need to be accommodated, the design and creation of a quick, accommodating and low-cost emergency hut is advantageous. This project also provides a living service for both refugees and homeless people. It is low cost, modular, and easy to use. More than that it is feasible and it makes it possible to accommodate people for a longer period of time, rather than a very short temporary housing solution such as tents. / Det har skett en signifikant ökning av jordbävningar och andra katastrofer i världen. Med rekordstora stormar och naturkatastrofer som förstör i delar av världen måste många människor nu hantera efterverkningar och återuppbyggande, och hemlöshet är en av de faktorer som uppstår och som påverkar människor mest. Det här examensarbetet syftar till att skapa en boendelösning för offer för jordbävning och andra naturkatastrofer och krig. Det hopfällbara hemmets design är ett koncept för krisboende med enkelt montage och installering. Om man betänker den situation som människor hamnar i som blir hemlösa vid en katastrof, kan en design av en snabb och billig boendelösning som krisboende ge enormt mycket. Projektet kan också vara en boendeservice till flyktingar och människor som är hemlösa av andra anledningar än katastrofer. Det tillverkas för en låg kostnad och är möjlig att använda som modul och enkel att sätta upp. Men viktigare än det är att den ger möjlighet att härbergera människor under en längre tid till skillnad från mer temporära lösningar som exempelvis tält. Det hopfällbara hemmet är gjort av hållbart material, den använder grön energi och lyser upp staden. Den är utrustad med vertikala trädgårdar för att användarna ska kunna odla egna grönsaker och den återvinner vatten från regn. Den innehåller basala hopfällbara möbler och rumsavdelare som ger känsla av hemtrevnad och bekvämlighet. housing home modular prefabricated urgent temporary foldable collapse catastrophic hut earthquake collapsible disaster life reborn sustainable green catastrophy service service design semantics refugee homeless design product design industrial design rescue emergency accommodate accommodation catastrophe solar energy hybrid aftermath humanitarian social war civil war civil civilization accommodating housing alternative housing

684	從個人差異看商品設計美感的效果--以消費者商品美感中心性(CVPA)為例 / The influence of product design aesthetics on consumers' responses: Exploring consumers' Centrality of Visual Product Aesthetics as a moderator 范勻瑄 Unknown Date (has links) 近年來大型消費性電子公司均致力發展商品外型的設計美感，試圖以具有視覺美感的商品吸引消費者的目光，以獲得更高的利潤。但本研究認為廠商在追逐商品設計美感時，也應探討消費者差異對於其美感反應的影響；以及不同商品以美感外型包裝時，對消費者的效果差異。對此，本研究以Bloch, Brunel & Arnold（2003）提出的消費者商品美感中心性（CVPA）、商品與自我一致性等概念，探討消費者對美感的心理差異，如何影響其對於商品設計美感的反應。同時並探討商品外顯性的差異，對於消費者的美感反應是否具有調節效果。透過消費者美感中心性、商品設計美感、以及商品外顯性的222三因子實驗設計，本研究以3C商品為實驗商品，並以線上實驗的方式進行。研究結果如下： 1. 消費者重視美感的程度與商品設計美感間的一致性，會影響其對於商品設計的愉悅反應。 2. 商品呈現順序會調節不同CVPA消費者對於商品設計的愉悅、品牌興趣、自我與品牌連結、認知價值等反應。 3. 重視美感程度差異的消費者，並不會因為商品外顯性的調節而影響其美感反應。 4. 商品外顯性與商品設計美感之間具有交互效果：對於高外顯商品而言，高美感設計可有效提高消費者的認知價值，但低外顯商品若以高美感設計呈現，亦可使消費者因超乎預期的感受而倍感愉悅。 5. 消費者對於美感在認知層面的自我與品牌連結反應，會顯著受到CVPA「敏銳」面向的影響；在情感層面的美感評估、態度、愉悅等反應，則會顯著受到「價值」面向的影響；在行為層面的品牌興趣、購買意圖，則會顯著受到「反應」層面的影響。 / The role of aesthetical quality of a product has been placed much importance these years in the manufacturing industry, especially in consumer electronic industry. While developing products with aesthetical quality, it is also important to understand how consumers responded to products with high and low levels of aesthetic quality. The present study explored the moderating role of consumers’ psychological differences on their aesthetic responses, and also examined how differently they responded to products that differed on aesthetic quality and conspicuousness. This study adopted the concept of Centrality of Visual Product Aesthetics developed by Bloch, Brunel & Arnold (2003) and drew upon the concept of self-product image consistency to explore how consumers’ aesthetic orientation influence their responses to products with high and low aesthetic design. Moreover, the influence of product differences has also been considered. The proposed hypotheses were tested by a three-factor on-line experiment. The results are as follows: 1. The consistency of consumers’ CVPA and products’ design aesthetics influenced consumers’ pleasant feelings. 2. The order of how the stimuli were presented moderated the consistency effect mentioned above, especially on responses such as: pleasure, brand interest, self-brand connection, and perceived value toward the product. 3. For consumers with different levels of CVPA, the products’ conspicuousness did not moderate their aesthetic responses toward the product with high and low aesthetic designs. 4. There was an interaction between “product conspicuousness” and “product design aesthetics” on consumers’ “perceived value” and “pleasant feelings” toward product designs. 5. Consumers’ aesthetic responses were influenced by different dimensions of CVPA: “Acumen” accounted for significant variance in “self-brand connection,” “Value” explained significant variance in their attitudinal responses toward the product, and “Response” significantly predicted the variance in their behavioral responses. The implications and suggestions for future studies and practitioners were also discussed.

685	The Future of Arabic Music: No sound without silence Khodier, Nesma Magdy, VCUQ 01 January 2016 (has links) For centuries, Arabic music has been intrinsically linked to Arab culture and by extension bonded to the environmental landscape of the region, reflecting their emotions, moods, and behaviors. Numerous technological advancements in the latter half of the twentieth century, have greatly affected the rich legacy of Arabic music, significantly impacting the natural progression of traditional Arabic musical genres, scales, and instrumentation. This thesis serves as an introduction to generative methods of music production, specifically music generated through gestures. Through generative music, and its unique ability to map gestures to different musical parameters, music can be produced using computer algorithms. The outcome of this thesis aims to demystify the intricacies of recent technological advancements to enable the musician and the audience to incorporate responsive technology into their ensembles. This approach aims to further evolve Arabic music, using the concepts of Arabic music creativity while addressing international accessibility through integration. The intention of this thesis is to bridge between the contemporary and the traditional Arabic audiences and provides insight into a possible future of Arabic music based on its own fundamental principles.

686	Systemic approach and decision process for sustainability in chemical engineering : Application to computer aided product design / Approche systémique et processus décisionnel pour le développement durable en génie des procédés : Application à la substitution de produits par formulation inverse Heintz, Juliette 23 October 2012 (has links) Dans un contexte de prise en compte croissante des enjeux environnementaux, l'industrie de la chimie et des procédés se retrouve confrontée à des problématiques de substitution de molécules. Les méthodes de formulation inverse, qui consistent en la recherche assistée par ordinateur de molécules satisfaisant un ensemble de contraintes, répondent de manière efficace à ces problématiques. A partir de l'analyse systémique des usages et fonctionnalités nécessaires dans ce contexte, nous développons un outil logiciel de formulation inverse mettant en oeuvre un algorithme génétique. Celui-ci est capable d'explorer un espace de solutions plus vaste en considérant les mélanges et non les molécules seules. Par ailleurs, il propose une définition des problèmes très flexible qui permet la recherche efficiente de molécules issues de filières renouvelables. En s'appuyant sur l'ingénierie système et l'ingénierie d'entreprise, nous proposons un processus formel de prise de décision pour la substitution de produit dans un contexte industriel. Ce processus de décision multi-critères englobe les phases de définition des exigences, de génération de solutions alternatives, de sélection de la meilleure alternative et de mise en oeuvre du produit. Il utilise une approche dirigée par les modèles et des techniques de prises de décision qui garantissent un alignement opérationnel en complément de l'alignement stratégique. A travers un cas d'étude, nous montrons comment l'utilisation conjointe de notre outil de recherche par formulation inverse et de notre processus de décision permet une démarche environnementale de substitution de produit à la fois efficiente et conforme à la réalité de l'entreprise. / In a context where environmental issues are increasingly taken into account, the chemical related industry faces situations imposing a chemical product substitution. Computer aided molecular design methods, which consist in finding molecules satisfying a set of constraints, are well adapted to these situations. Using a systemic analysis of the needs and uses linked to this context, we develop a computer aided product design tool implementing a genetic algorithm. It is able to explore a wider solution space thanks to a flexible molecular framework. Besides, by allowing a very flexible setting of the problem to be solved, it enables the search of molecules sourced from renewable resources. Based on concepts from system and enterprise engineering, we formalize a decision making process dedicated to the product substitution in an industrial context. This multi-criteria decision process includes the phases of the requirements definition, of the generation of alternative solutions, of the selection of the best alternative and of the product application. It uses a model driven approach and decision making techniques that guaranty an operational alignment in addition to the strategic alignment across the chemical enterprise. Through a case study, we expose how the combination of our computer aided product design tool and our decision making process enables an environmentally compliant approach of product substitution which is both efficient and in adequacy with enterprise context.

Esta tese tem por objetivo analisar não só a cultura de design na micro e pequena indústria, tomando como exemplo o setor moveleiro no estado de São Paulo, como também, dentro do contexto estratégico, quais são os fatores que interferem e decidem o sucesso ou não da inserção da ferramenta de design e sua gestão. Neste sentido,são estudados os aspectos relativos ao design como diferencial do negócio, a estrutura organizacional das micro e pequenas indústrias, a Gestão de Design como sistema integrador de competências, seu consumidor, e como toda esta estrutura desenvolve as características do design na organização, para finalmente propor um modelo teórico que possa indicar soluções estratégicas para a inserção do design dentro da Micro e Pequena Indústria. A tese inicia-se na proposta de que o design e sua gestão podem alavancar a indústria pela sua visão estratégica, trazendo não só inovação nos conceitos desenvolvidos, própria da cultura do design, bem como sendo um fator integrador de estratégias no âmbito do design e do marketing. O estudo mostra que a Gestão de Design e o Modelo teórico aqui proposto podem ser um componente importante para implementar soluções competitivas e integradoras com outras ferramentas estratégicas da organização. / In recent years, there has been great interest in design innovation and contribution to the business; however, this business vision, focusing on design, is not yet fully in line with the industry strategy. This thesis aims to examine not only the design culture in the Micro and Small Industry, taking as an example the furniture sector in the State of São Paulo, but also within the strategic context and business. These factors interfere with and help decide the success or failure of an integration design tool and its management. In this sense, the aspects studied are design as a differential business, the organizational structure of Micro and Small Industries, Design Management as a system integrator skill, customers, and how all this structure develops the design features in the organization to finally propose a theoretical model that can indicate strategic solutions for integrating design within the business vision. The thesis begins by proposing that design and management can leverage the industry towards its strategic vision, not only innovating developed concepts, its own design culture, but integrating factor strategies in design and marketing as well. The study shows that Design Management and the Theoretical Model proposed herein can be an important component to implement competitive solutions and integrated with other strategic organizational tools.

Information defined at early design stages needs to be recovered at all stages of the life cycle of a product. To accomplish this, information models that incorporate intelligence and enable the representation of the real world are necessary. On the other hand, electronic products manufacturers need to comply with environmental requirements present in regulatory frameworks as the RoHS Directive in order to offer their products in several countries. The present work proposes the application of semantic models for helping companies meet the requirements established by the RoHS Directive. A model, created using a reference ontology, establishes semantic relationships between entities that represent product lifecycle stages, product structure and business objects. Business processes, modeled in the form of activity and information flows, are linked to RoHS requirements that can be viewed through the reports in the Essential Project open source framework. The resulting semantic model is, therefore, useful for converting environment-related needs to design requirements through a product development process that addresses the RoHS Directive. A consumer electronics product has been selected for demonstrating the feasibility of the proposed solution.

689	A Feasibility Map-Based Framework and Its Implementation for Selection in Engineering Design Nandhini Devi, N January 2015 (has links) (PDF) A pragmatic method for selecting components and devices from a database or parameterized models is developed in this thesis. The quantitative framework presented here is sufficiently general to accommodate an entire device assembly, a component, or a sub-assembly. The details pertaining to a device or a component are classified into three sets of variables: (i) user-specifications, s (ii) device parameters, p , and (iii) device characteristics, c . Functional, practical, and performance-related attributes that a user can provide comprise user-specifications. Since, most often, a specification cannot be specified as a single number, we allow the user to enter a range with lower and upper bounds. Device parameters comprise the geometry and material properties, and device characteristics include functional requirements and performance criteria. Thus, for a device, all its functional and utility attributes are contained in the union of sets s and c , whereas the geometry and the material properties are in set p . The equations governing the physical behavior of the device are written in terms of s , p , and c . These equations may sometimes be readily available; when they are not, it may be necessary to formulate them as required. By solving the governing equations along with the inequalities that arise from the lower and upper bounds on s , we obtain feasible ranges on p and c . Then, for any pair of device characteristics, a 2D feasible map is drawn, to visually portray the consequences of user-specifications. If the feasible map is null, small, or large, it indicates that the user-specifications are infeasible, stringent, or there is much scope for design, respectively. This can be inferred even before the designs are considered. Juxtaposed on the feasible map are points or lozenges corresponding to the quantitative attributes of the entries in the database. The ones that lie inside the feasible map can be reckoned as meeting the user-specifications and thus, enabling selection. On the other hand, if there is no database or none of the devices in the database lie inside the feasible map, we can identify the feasible ranges of all the design parameters for every point inside the feasible map. This information is useful to the designer to redesign and arrive at feasible designs by using parameterized models of the device. A Graphical User Interface (GUI) is developed to facilitate the user-interaction. The utility of the selection framework is demonstrated with a variety of case-studies including miniature pumps, heat pulse-based soil-moisture sensors, springs, flywheels, compliant mechanisms, micromechanical suspensions, etc. The latter two use kineto-elastic characteristics of deformable components. The framework, when used for materials selection, can be seen as an extension of Ashby’s materials selection method. This is also illustrated with two examples.
