Bride squad

Huarancca Escobar, María Luisa, Jiménez Armijo, Daniel Enrique, Juskamayta Ferro, Cesar, Li Loo, Andrea Mey Len, Santisteban Arbaiza, Sergio Andrés 01 July 2019 (has links)
Bride Squad es un modelo de negocio que satisface las demandas del mercado de despedidas de solteras, otorgando productos innovadores que complementan las temáticas propuestas por evento. El problema que nos permite llevar a cabo este proyecto va más allá de la tendencia de consumo y la casi inexistente oferta de productos de calidad que puedan ser utilizados para la despedida de soltera de una gran amiga, hermana o hija. Decidimos investigar algunos componentes del mercado, como: el origen del problema, las preferencias del consumidor y la necesidad de incluir productos ajustados a las exigencias de este. Posteriormente, por medio de entrevistas y encuestas; adicionalmente a analizar fuentes secundarias; hemos podido validar la siguiente hipótesis: “Las personas que realizan una despedida de soltera no encuentran con facilidad una tienda que les brinde accesorios y prendas que vayan con sus gustos”. En este trabajo aportamos una extensa investigación sobre dicho mercado, tales como: tamaño de mercado, análisis externo e interno, experimentos de validación, y demás. Adicionalmente, hemos utilizado herramientas aplicadas de administración; tales como, el modelo de Canvas, matriz de flujogramas, diagramas de Gantt, FODA, matriz de Peyea, matrices EFE y EFI, entre otras. Finalmente, hicimos uso de herramientas financieras, las cuales, junto con el pronóstico de ventas estimado, nos permitió presentar el Estado de Resultados y Balance General. Con estos y el costo de capital, determinamos el VAN de nuestro modelo de negocio; así como, los ratios oportunos para afirmar con que nuestro modelo es económicamente viable y escalable. / Bride Squad is a business model that meets the demands of the bachelorette market, providing innovative products that complement the themes proposed by event. The problem that made us develop this project is the almost non-existent offer of quality products that can be used at a bachelorette party of a friend, sister or daughter. We decided to investigate some market components, such as: the origin of the problem, consumer preferences and the needs to include these in the market to solve the problems. Subsequently, through interviews and surveys and the analysis of secondary sources, we were able to validate the following hypothesis: "People who organize a bachelorette party cannot easily find a store that provides them with accessories and clothes that match their tastes". In this work we provide extensive research on this market, such as: market size, external and internal analysis, validation experiments, and so on. Additionally, we applied administration tools; such as, canvas model, flowchart matrix, Gantt diagrams, SWOT, Peyea matrix, EFE and IFE matrixes, among others. Finally, we made use of financial tools, which together with the estimated sales forecast, allowed us to present the Income Statement and Balance Sheet. With these and the cost of equity, we determine the NPV of our business model; as well as, the appropriate ratios to affirm that our model is economically viable and scalable. / Trabajo de investigación

Volvo Cars: Frunken : Ett utvecklingsarbete som skapar mervärde för frunken

Berntsson, Anna, Svensson, Ellinor January 2021 (has links)
The electric car market is growing at a furious pace and cars are becoming increasingly advanced. When the internal combustion engine is replaced with an electric motor, a vacuum is created in the front of the car. Car manufacturers have taken advantage of this and created a luggage compartment in the front. The space is called frunk based on a combination of the words front and trunk.  Car owners currently have difficulty finding areas of use for the frunk as the limited geometry of the space makes it generally difficult to find objects that fit. Products with a view to creating added value for the funk are almost non-existent on the market. The purpose of the degree project is to provide use cases and concept work for a purposeful but rarely used frunk, as an attractive product range for a future Volvo car fleet, regardless of the car segment. shall be malleable according to Volvo's various car segments.  Together with Volvo Cars, the project group has developed a number of concepts that puts the user at the center. The project group has maximized the volume, modified the material and found new solutions, all to make full use of the space. To further optimize the space, the project team has created the concept frunk-kit. Frunk-kit as a concept is a business idea that includes selectable accessories gathered in a custom-made bag. The options vary according to the customer benefit for different target groups and global markets. This concept gives the customer the opportunity to choose the options that suit their lifestyle and the enhances the user experience. The Frunk-kit concept is based on finding the right use for the space and in order to be able to demonstrate the function of the frunk-kit, the project group has created a prototype where the active lifestyle is at the center based on the XC40 recharge target group. By combining the range of Volvo accessories with the frunk, we create new opportunities for the customer to get where they want, with everything they need.

"Mobile Fashion" Application

Kashanipour, Morvarid January 2012 (has links)
This master thesis investigates studies on fashion oriented people according to the "Outfit-Centric Accessories" concept. The outfit-centric accessories concept originated from recent research study by Juhlin and Zhang (2011) about mobile phone representation in fashion and Aesthetic of Interaction area of Human-Computer Interaction (HCI). The term outfit-centric accessories originated from clothing and wearer. In this concept an outfit is playing a role as the centerpiece and a mobile phone is functioning as a sort of an accessory that can be added to an outfit. The main aim here is to explore design solution for matching the visual appearance of mobile device with different outfit of a person. The first phase of this thesis is based on a research conducted through a literature review on the Aesthetic Interaction and the Experience-Centered design approach. Literature study has been followed by studies the relation between the fashion and technology and the outfit-centric accessories concept precisely. The findings that are presented here are based on field studies on fashion oriented people who are interested in mobile phone design. Filed studies were conducted through gathering input entries from social networking services such as Facebook and Blogger, survey of questionnaire on outfit matching mechanism, and inquiring people around. The findings are described the outfit "Match Mechanism" and the "social activities around the outfit matching" in relation to the concept. These descriptions have led the project to the system design and development phase regarding the outfit-centric accessories concept. This phase resulted in the Android based mobile application named "Mobile Fashion". This application enables a user to match a mobile device with variety of clothing in the form of a background image, cover, or printable sticker (skin phone) and it allows a user to participate in social services by sharing the look with others. It is worth mentioning that "Mobile Fashion" application presented in Vinnova-nytt (June 2011, No.3, p15) and International Joint Conference on Ambient Intelligent (AmI'11 November, 16, 2011, Amsterdam) (see appendix 14 and 15).

New consumption identities in virtual worlds : the case of 'Second Life'

Nikolaou, Ioanna January 2011 (has links)
The dynamic development of new technologies influences consumers in many different ways reaching far beyond the shift in consumption patterns, challenging the way consumers live their lives. The role of new information technologies is continually growing in our daily lives changing the way we see the self and the world around us. Consequently, the advent of the computer culture incites a radical rethinking of who we are and the nature of being human, which clearly illustrates the postmodern age. As a result, over the past decades consumer research has moved away from simply viewing consumers as information processors to consumers as socially conceptualized beings. This Consumer Culture Theory (CCT) movement views consumers and consumer behaviour as articulations of meanings and materiality within the productive of complex cultural milieu. This ethnographic thesis focuses on the three-dimensional virtual world of Second Life, which is a 'Real Life' simulation and where the residents represent themselves through 'avatars', creating a kind of virtual materiality. This raises interesting questions for consumer researchers, not just about how consumption is enacted, produced and articulated within this environment, but also in relation to theoretical and methodological issues. More specifically, this thesis critically examines the development of interpretive consumer research and the emergence of the Consumer Culture Theory framework in the context of the juxtaposition of reality and hyperreality and takes a position which goes beyond the 'body in the net/physical body' binary. Therefore, this thesis places the 'avatar-as-consumer' at the centre of the research focus. The current thesis develops a theoretical framework which examines the role of consumption in resolving key paradoxes. Moreover, it extends the netnography framework from mainly text based research to the visual characteristics of virtual worlds so that it can be useful for the study of complex online environments and as a result, how the role of the researcher goes beyond netnography to virtualography is discussed.

No. of bitstreams: 1 TESE Tweens.docx: 3624731 bytes, checksum: efb78944b4bfb84d2073d34e9b44ebb2 (MD5) Previous issue date: 2013-12-16 / “Tweens” are children, especially girls, included in an age group that can vary, depending on the author of the study, from seven to fourteen years of age. They are, thus, in a stage between childhood and adolescence. More important than their chronological age is the economic behavior that they have developed. As consumers, they have behavioral quirks and attitudes due to their social and emotional experiences. For example, they have intense concern as to how they are seen by those around them and resort to various devices to recognize and express themselves in their social relations. One of these devices involves the use of material goods to express identity and give significance to their emotions and the word around them. As they participate in society as consumers they have become increasingly eloquent and active in their consumer relations. The result is that this segment is described by some scholars as the richest and most influential generation of the meanings that tweens, aged eight to twelve years, attach to personal accessories. Ethnographic inspiration was chosen as an effective research method during four months of fieldwork with participant observation of ten tweens and interviews with relatives and accessory store owners. Secondary sources of information, magazines and social networks, also provided information for understanding the research problem. The results reveal the use of accessories as important tools for social adjustment, either because they aide tweens in expressing themselves to those around them, or with regard to social expectations regarding an acceptable appearance. Accessories are especially useful as they “play the game” of social life and to establish and strengthen emotional ties. In addition to the theoretical contribution regarding studies of consumer behavior in childhood, this paper also aims to provide information as to marketing decisions and the social nature of peer relations among this segment of the consuming population / Tweens são consideradas as crianças, especialmente as do sexo feminino, incluídas em uma faixa etária que pode variar, dependendo do autor do estudo, de sete a quatorze anos e, portanto, estão em um estágio entre a infância e a adolescência. Mais importante, contudo, do que os aspectos cronológicos que alocam os tweens entre crianças e adolescentes, os consumidores dessa faixa etária apresentam peculiaridades comportamentais e de atitudes devido à fase de transição social e emocional em que se encontram. Por exemplo, eles apresentam uma preocupação intensa quanto ao modo como são vistos por aqueles com quem convivem e lançam mão de artifícios variados para se reconhecerem e se expressarem nas suas relações sociais encontrando no significado dos bens uma via útil para declarar sua identidade, manifestar suas emoções e ressignificarem o mundo a sua volta. Partícipes cada vez mais eloquentes e ativos das relações de consumo, este segmento é ainda descrito por alguns estudiosos como a geração mais rica e influente da história econômica. Amparado por teorias sobre a participação das crianças no universo do consumo e sobre a atribuição de significado aos bens, sobremodo para a expressão de identidade, o estudo aqui alvitrado apresenta, por meio de análise interpretativista, os significados que tweens com idade entre oito e doze anos atribuem a acessórios pessoais. O método de pesquisa, de inspiração etnográfica, se efetivou em quatro meses de pesquisa de campo com observação participante de dez tweens e com entrevistas com familiares e proprietários de loja de acessórios. Fontes secundárias de informações como revistas e redes sociais também serviram para lançar luz ao entendimento do problema de pesquisa. Os resultados convergem para o uso dos acessórios como instrumentos importantes de ajuste social, seja porque ajudam as participantes a se expressarem e a se posicionarem frente a quem convivem, seja por se prestarem a auxiliar as tweens no que diz respeito às expectativas sociais quanto à boa aparência. Em nível mais particular, os acessórios se prestam igualmente a práticas performáticas lúdicas e de competências e ainda são instrumentos bastante úteis à aproximação e reforço de laços afetivos. Para além da contribuição teórica no que tange ao aprofundamento dos estudos sobre o comportamento do consumidor infantil e, sobretudo, do significado como bojo do processo de decisão de compra, este trabalho pretende, ainda, oferecer subsídios para deliberações de naturezas mercadológica e social ao perscrutar um fenômeno tão subjetivo de um público importante para essas duas esferas.

No. of bitstreams: 1 Flora_BrunoFagundes_M.pdf: 2971179 bytes, checksum: 98fc79d21db40bfb0bbe58d6d20ec80e (MD5) Previous issue date: 2011 / Resumo: É proposta uma metodologia de projeto e de calibração de um medidor de fração de vazio para escoamento de gás e líquido operando com o princípio de impedâncias elétricas baseado em simulação numérica. O desenvolvimento do sensor é feito utilizando-se de um software de volumes finitos para a otimização heurística da geometria dos eletrodos e também para a criação de uma curva de mapeamento do sinal para fração de vazio de acordo com as características elétricas do fluido em questão, ou seja, características capacitivas (óleo, gás), resistivas (água) ou ambas. Utilizando o conceito de similaridade entre modelo e protótipo foi possível reduzir os resultados computacionais a simples expressões algébricas que relacionam diretamente a fração de vazio com a voltagem do circuito e estender este resultado para tubulações de quaisquer diâmetros. Testes estáticos e dinâmicos são feitos com o propósito de validar o estudo computacional e verificar o desempenho do sensor operando com diferentes padrões de escoamento / Abstract: A methodology for design and calibration of a void fraction meter for gas and liquid flow operating on the principle of electrical impedance is developed based on numerical simulation. The sensor development is done using a finite volume software. The numerical analysis allowed a heuristic geometry optimization of the electrodes and also created a mapping curve for the void fraction signal according to the electrical characteristics of the fluid in consideration, ie, capacitive (oil, gas), resistive (water) or both. Using the concept of similarity between model and prototype it was possible to reduce the computational results to simple algebraic expressions that relate directly the void fraction with the voltage output and extend this result to pipes of any diameter. Static and dynamic tests were done in order to validate the computational study and verify the performance of the sensor operating with different flow patterns / Mestrado / Termica e Fluidos / Mestre em Engenharia Mecânica

Orientador: Antonio Celso Fonseca de Arruda / Dissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Engenharia Mecânica / Made available in DSpace on 2018-08-21T04:30:34Z (GMT). No. of bitstreams: 1 Gouvea_MarcoAurelio_M.pdf: 3731327 bytes, checksum: 1728d314950efa177f222899453e2bdb (MD5) Previous issue date: 2012 / Resumo: No mercado é possível encontrar grande variação de dispositivos de retenção de crianças, parte destes dispositivos é desenvolvida para acomodar crianças de diferentes grupos de massa definido nos requisitos legais Brasileiros, Europeus e Americanos. Existe sobreposição entre os grupos, permitindo que a mesma criança utilize dispositivos de retenção de diferentes grupos. Este trabalho tem como propósito comparar o comportamento do manequim, que simula ocupante de três anos de idade com 15 kg, em teste dinâmico similar ao da ECE R44 com dispositivo de retenção de criança instalado conforme Grupo I, com cinto de segurança cinco pontos, e quando instalado conforme Grupo II, com cinto de segurança veicular de três pontos. Para suportar as conclusões obtidas foi utilizado dado dos testes de certificação do dispositivo de retenção de criança Grupo I e II. O dispositivo de retenção de criança utilizado neste estudo é certificado conforme INMETRO portaria 38, sendo ancoradas ao equipamento de teste pelo cinto de segurança três pontas conforme indicação do fabricante. Os testes dinâmicos foram executados com trenó que desacelera em função do tempo conforme curva padrão da ECE R44. Esta dissertação conclui que a resposta dinâmica do manequim depende do projeto de instalação do dispositivo de retenção de criança ao veículo e que considerando a menor movimentação da cabeça do manequim e menores lesões da cabeça, aceleração do peito, região pélvica e púbica, o dispositivo de retenção testado instalado conforme Grupo II apresentou melhor desempenho nos testes dinâmicos que o dispositivo instalado conforme Grupo I, portanto o transporte de criança de três anos de 15 kg é mais seguro com o dispositivo de retenção Grupo I / Abstract: Many CRSs models are available in the market; several are developed to accommodaté different mass group children. There is overlap among the mass groups and as consequence the same child can use a different mass group CRS. The purpose of this paper is to compare the dummy kinematic in a dynamic test similar to ECE R 44 with the same CRS design installed according to Group I (five points harness) and installed according to Group II (vehicle's three point safety belt). To support the conclusions the data of CRS Certification test for Group I and II were used. The chosen CRS is certified for Brazilian market according to INMETRO administrative rule 38 and is anchored to the vehicle by its three point safety belt according to the CRS manufacturer's recommendation. The dynamic tests were performed on Sled subjected to the ECE R 44 standard acceleration vs. time curve. The harness loads and vehicle safety belt loads will be gathered and dummy kinematic were recorded with high speed digital cameras. The results are tabulatéd and compared with focus on the relevant performance differences. This study conclude that dynamic dummy response depend on the CRS design used to install the device to the vehicle and considering the lower ATD head excursion, the lower injuries at head, pelvis, pubic and chest acceleration the tested CRS installed according to Group II (five points harness) present better safety performance on dynamic tests than tested CRS installed according to Group I (vehicle's three point safety belt) / Mestrado / Materiais e Processos de Fabricação / Mestre em Engenharia Mecânica
