There are information about Gislotica Company and also first analysis of problem. In next part is presented way to figured out the task and described all issues connected with designed machine. In last part were made some conclusions about problems and results. There is a place not only for sum up design process but also my develop during the project. I repeatedly pointed out which issues were new for me. A lot of times I focus on myself and gained experience and information about design process.

El lenguaje gráfico de Eduardo Chillida como aportación conceptual para la identidad tipográfica de la Universidad del País Vasco UPV/EHU

El valor de la documentación especializada en las fases del diseño / The value of specialized documentation in the design process este proyecto de investigación financiado por la Universidad del País Vasco/Euskal Herriko Unibertsitatea UPV/EHU-PES 11/31, a través de su programa de investigación estratégica, tiene como objetivo la creación de la tipografía de identidad visual corporativa de la Universidad del País Vasco UPV/EHU, cuyo inicio conceptual para dotar de unas características de identidad visual corporativa a la UPV/EHU, ha sido planteado desde las especulaciones estéticas sobre la forma, materializadas por Eduardo Chillida. En la producción gráfica de este artista encontramos una sutil coincidencia con principios vitales para la creación tipográfica, en cuanto al planteamiento de formas dinámicas y constructivas, en las que el rigor geométrico es vencido por una suerte de organicidad que parte del núcleo mismo de la estructura "cursus", por: la fuerza vital que imprime la acción modulada del gesto "ductus"; por la dialéctica entre lo lleno y lo vacío forma/contraforma, por el impulso y la espontaneidad carácter, o por la afirmación de un lenguaje plástico en la cultura diferenciada del medio en el que se vive la identidad.

Asiakkaan osallistuminen innovaatio- ja tuotekehitysprosessiin

Tässä tutkimuksessa tarkastellaan asiakkaan ja valmistajan osallistumista yhteistoiminnalliseen innovaatio- ja tuotekehitysprosessiin ja sen vaikutuksia yritysten kilpailukykyyn. Asiakaslähtöinen avoin innovaatio- ja tuotekehitystoiminta on yksi merkittävä kilpailuedun lähde, sillä se mahdollistaa tuotevariaatioiden nopeamman lanseerauksen ja asiakastarpeiden huomioimisen tuotekehitystoiminnassa. Tämän empiirisen tutkimuksen tavoitteena oli selvittää millä tavoin kulutustavaroihin kuuluvien muoti- ja sportvaatteiden suunnittelussa yhteistoiminnallinen innovaatio- ja tuotekehitystoiminta on mahdollista toteuttaa ja miten sitä voidaan hallita. Tutkimus toteutettiin kvalitatiivisena tapaustutkimuksena. Empiirinen aineisto kerättiin teemahaastatteluina tapausorganisaatiosta. Yhteistoiminnallisesta kehittämisestä ei ole olemassa yhtä kattavaa teoriaa, jota voitaisiin hyödyntää. Tämän vuoksi yritysten on luotava itse yhteistoiminnallisen innovaation ja tuotekehityksen viitekehys, joka parhaiten palvelee liiketoiminnan tarpeita. Viitekehys ja käytettävät menetelmät sekä yhteistoiminnallisuutta tukevat työvälineet ovat riippuvaisia mm. toimialasta ja sen markkinatilanteesta, liiketoimintamalleista, yrityksen toimintaympäristöstä, asiakkaista ja kehittämisen kohteeksi valitusta tuotealueesta. Empiirinen tutkimus osoittaa, että yhteistoiminnallinen innovaatio voi olla kilpailuedun lähde sekä valmistajille että asiakkaalle, mutta vaatii aina yrityskohtaista sopeuttamista. Tutkimuksen mukaan hyvin johdettu yhteistyömalli, oikeat tuotevalinnat ja asiakasinformaation monipuolinen hyödyntäminen vaikuttavat positiivisesti kehittämisprojektin tuloksiin.

Effect of Geometric Uncertainties on the Aerodynamic Characteristic of Offshore Wind Turbine Blades

Offshore wind turbines operate in a complex unsteady flow environment which causes unsteady aerodynamic loads. The unsteady flow environment is characterized by a high degree of uncertainty. In addition, geometry variations and material imperfections also cause uncertainties in the design process. Probabilistic design methods consider these uncertainties in order to reach acceptable reliability and safety levels for offshore wind turbines. Variations of the rotor blade geometry influence the aerodynamic loads which also affect the reliability of other wind turbine components. Therefore, the present paper is dealing with geometric uncertainties of the rotor blades. These can arise from manufacturing tolerances and operational wear of the blades. First, the effect of geometry variations of wind turbine airfoils on the lift and drag coefficients are investigated using a Latin hypercube sampling. Then, the resulting effects on the performance and the blade loads of an offshore wind turbine are analyzed. The variations of the airfoil geometry lead to a significant scatter of the lift and drag coefficients which also affects the damage-equivalent flapwise bending moments. In contrast to that, the effects on the power and the annual energy production are almost negligible with regard to the assumptions made.

Playing for Real: Designing Alternate Reality Games in Learning Contexts

Alternate Reality Game (ARG) represent a new genre of transmedia practice where players hunt for scattered clues, make sense of disparate information, and solve puzzles to advance an ever-evolving storyline. Players participate in ARGs using multiple communications technologies, ranging from print materials to mobile devices. However, many interaction design challenges must be addressed to weave these everyday communication tools together into an immersive, participatory experience. Transmedia design is not an everyday process. Designers must create and connect story bits across multiple media (video, audio, text) and multiple platforms (phones, computers, physical spaces). Furthermore, they must engage with players of varying skill levels. Few studies to-date have explored the design process of ARGs in learning contexts. Fewer still have focused on challenges involved in designing for youth (13-17 years old). In this study, I explore the process of designing ARGs as vehicles for promoting information literacy and participatory culture for adolescents (13-17 years old). Two ARG design scenarios, distinguished by target learning environment (formal and informal context) and target audience (adolescents), comprise the two cases that I examine. Through my analysis of these two design cases, I articulate several unique challenges faced by designers who create interactive, transmedia stories for – and with – youth. Drawing from these design challenges, I derive a repertoire of design strategies that future designers and researchers may use to create and implement ARGs for teens in learning contexts. In particular, I propose a narrative design framework that allows for the categorization of ARGs as storytelling constructs that lie along a continuum of participation and interaction. The framework can serve as an analytic tool for researchers and a guide for designers. In addition, I establish a framework of social roles that designers may employ to craft transmedia narratives before live launch and to promote and scaffold player participation after play begins. Overall, the contributions of my study include theoretical insights that may advance our understanding of narrative design and analysis as well as more practical design implications for designers and practitioners seeking to incorporate transmedia features into learning experiences that target youth.

SUR Hand: A Soft Underactuated Robotic Hand

Soft robots are robots made mostly or completely of soft, deformable, or compliant materials. As humanoid robotic technology takes on a wider range of applications, it has become apparent that they could replace humans in dangerous environments. Current attempts to create robotic hands for these environments are very difficult and costly to manufacture. Therefore, a robotic hand made with simplistic architecture and cheap fabrication techniques is needed. The goal of this thesis is to detail the design, fabrication, modeling, and testing of the SUR Hand. The SUR Hand is a soft, underactuated robotic hand designed to be cheaper and easier to manufacture than conventional hands. Yet, it maintains much of their dexterity and precision. This thesis will detail the design process for the soft pneumatic fingers, compliant palm, and flexible wrist. It will also discuss a semi-empirical model for finger design and the creation and validation of grasping models.

ProjectION: Investigation Operative Networks

Corporations and enterprises have embraced the notion of shared experiences and collective workplaces by incorporating coworking places. A great deal of the methodology carries from the studio culture that architecture schools foster as well as think tank culture. Maker spaces and incubator spaces are prime examples of places that engender creative thought and products. This thesis seeks to explore the impact that architecture has on collaborative spaces with a focus on augmenting to their generated learning and design activities. The investigation explores the collaborative design process as a series of interactions between groups of individuals. This involves the impact of technology and its implications on those interactions. The goal of this thesis is not to further the use of a tool or systematic procedure, but to use architecture as a framing device to form places for collaborative processes.

The impact of geometric non-linearities on the fatigue analysis of trailing edge bond lines in wind turbine rotor blades

The accurate prediction of stress histories for the fatigue analysis is of utmost importance for the design process of wind turbine rotor blades. As detailed, transient, and geometrically non-linear three-dimensional finite element analyses are computationally weigh too expensive, it is commonly regarded sufficient to calculate the stresses with a geometrically linear analysis and superimpose different stress states in order to obtain the complete stress histories. In order to quantify the error from geometrically linear simulations for the calculation of stress histories and to verify the practical applicability of the superposition principal in fatigue analyses, this paper studies the influence of geometric non-linearity in the example of a trailing edge bond line, as this subcomponent suffers from high strains in span-wise direction. The blade under consideration is that of the IWES IWT-7.5-164 reference wind turbine. From turbine simulations the highest edgewise loading scenario from the fatigue load cases is used as the reference. A 3D finite element model of the blade is created and the bond line fatigue assessment is performed according to the GL certification guidelines in its 2010 edition, and in comparison to the latest DNV GL standard from end of 2015. The results show a significant difference between the geometrically linear and non-linear stress analyses when the bending moments are approximated via a corresponding external loading, especially in case of the 2010 GL certification guidelines. This finding emphasizes the demand to reconsider the application of the superposition principal in fatigue analyses of modern flexible rotor blades, where geometrical nonlinearities become significant. In addition, a new load application methodology is introduced that reduces the geometrically non-linear behaviour of the blade in the finite element analysis.

Pk-yritysten ympäristöllisen kestävyyden kehittäminen palvelumuotoilua hyödyntäen

Ympäristöllinen kestävyys on ajankohtaisempi asia kuin koskaan ja sen merkitys yritysten yhtenä kestävyyden osa-alueena kasvaa jatkuvasti. Erityisesti suuret yritykset pyrkivät erottumaan kilpailijoistaan ympäristöllisen kestävyyden avulla, mutta myös pk-yritykset olisi tärkeää saada mukaan toiminnan kehittämiseen. Aikaisemmat tutkimukset yritysten ympäristöllisestä kestävyydestä ovat keskittyneet pääosin käytössä oleviin menetelmiin ja kestävyyden kehittämisen suurimpiin haasteisiin. Tärkeää olisi tutkia myös sitä, miten pk-yritykset saataisiin mukaan kehittämään toimintaansa ympäristöllisesti kestävämmäksi. Tähän pyritään löytämään vastauksia tässä diplomityössä. Diplomityön tarkoituksena on tutkia sitä, millä tavoin pk-yritykset haluavat kehittää toimintaansa ympäristöllisesti kestävämmäksi. Työn tavoitteena on suunnitella pk-yritysten tarpeita vastaava palvelukonsepti niiden ympäristöllisen kestävyyden kehittämiseksi. Tutkimuksessa hyödynnetään palvelumuotoilua ja sen prosessin kolmea ensimmäistä vaihet-ta: asiakasymmärryksen hankintaa, luovaa ideointia sekä palvelukonseptin kehittämistä. Tutkimus on laadullinen tutkimus, jonka tutkimusmetodina toimii palvelumuotoilun tärkein osa-alue eli yhteissuunnittelu. Yhteissuunnittelu toteutettiin visuaalisten työpajojen avulla suunnitteluun osallistuvien pk-yritysten kanssa. Tutkimuksen tuloksena saatiin suunniteltua pk-yritysten tarpeisiin räätälöity palvelukonsepti niiden ympäristöllisen kestävyyden kehittämiseksi. Palvelun tärkeimpiä ominaisuuksia ovat jatkuva tiedon lisääminen, kokonaisuuden hahmottamista helpottava visuaalisuus sekä palvelun virallisiin standardeihin pohjautuva kokonaisuus. Lisäksi palvelu mahdollistaa toiminnan kehittämisen pienin askelin sen porrastetun menetelmän ansiosta. Yksi tärkeä ominaisuus on myös palvelun tarjoama mahdollisuus tietojen helppoon ja nopeaan doku-mentointiin sekä jalostamiseen.

Modos projetuais de simulação: uso de ferramentas de simulação térmica no processo projetual de arquitetura

This thesis aims to describe and demonstrate the developed concept to facilitate the use of thermal simulation tools during the building design process. Despite the impact of architectural elements on the performance of buildings, some influential decisions are frequently based solely on qualitative information. Even though such design support is adequate for most decisions, the designer will eventually have doubts concerning the performance of some design decisions. These situations will require some kind of additional knowledge to be properly approached. The concept of designerly ways of simulating focuses on the formulation and solution of design dilemmas, which are doubts about the design that cannot be fully understood nor solved without using quantitative information. The concept intends to combine the power of analysis from computer simulation tools with the capacity of synthesis from architects. Three types of simulation tools are considered: solar analysis, thermal/energy simulation and CFD. Design dilemmas are formulated and framed according to the architect s reflection process about performance aspects. Throughout the thesis, the problem is investigated in three fields: professional, technical and theoretical fields. This approach on distinct parts of the problem aimed to i) characterize different professional categories with regards to their design practice and use of tools, ii) investigate preceding researchers on the use of simulation tools and iii) draw analogies between the proposed concept, and some concepts developed or described in previous works about design theory. The proposed concept was tested in eight design dilemmas extracted from three case studies in the Netherlands. The three investigated processes are houses designed by Dutch architectural firms. Relevant information and criteria from each case study were obtained through interviews and conversations with the involved architects. The practical application, despite its success in the research context, allowed the identification of some applicability limitations of the concept, concerning the architects need to have technical knowledge and the actual evolution stage of simulation tools

Do modelo geométrico ao modelo físico: o tridimensional na educação do arquiteto e urbanista

In the teaching practice of architecture and urbanism in Brazil, educational legislation views modeling laboratories and workshops as an indispensable component of the infrastructure required for the good functioning of any architectural course of study. Although the development of information technology at the international level has created new possibilities for digital production of architectural models, research in this field being underway since the early 1990s, it is only from 2007 onwards that such technologies started to be incorporated into the teaching activity of architecture and urbanism in Brazil, through the pioneering experience at LAPAC/FEC/UNICAMP. It is therefore a recent experiment whose challenges can be highlighted through the following examples: (i) The implementation of digital prototyping laboratories in undergraduate courses of architecture and urbanism is still rare in Brazil; (ii) As a new developing field with few references and application to undergraduate programs, it is hard to define methodological procedures suitable for the pedagogical curricula already implemented or which have already been consolidated over the years; (iii) The new digital ways for producing tridimensional models are marked with specificities which make it difficult to fit them within the existing structures of model laboratories and workshops. Considering the above, the present thesis discusses the tridimensional model as a tool which may contribute to the development of students skills in perceiving, understanding and representing tridimensional space. Analysis is made of the relation between different forms of models and the teaching of architectural project, with emphasis on the design process. Starting from the conceptualization of the word model as it is used in architecture and urbanism, an attempt is made to identify types of tridimensional models used in the process of project conception, both through the traditional, manual way of model construction as well as through the digital ones. There is also an explanation on how new technologies for digital production of models through prototyping are being introduced in undergraduate academic programs of architecture and urbanism in Brazil, as well as a review of recent academic publications in this area. Based on the paradigm of reflective practice in teaching as designed by Schön (2000), the experiment applied in the research was undertaken in the integrated workshop courses of architectural project in the undergraduate program of architecture and urbanism at Universidade Federal do Rio Grande do Norte. Along the experiment, physical modeling, geometric modeling and digital prototyping are used in distinct moments of the design process with the purpose of observing the suitability of each model to the project s phases. The procedures used in the experiments are very close to the Action Research methodology in which the main purpose is the production of theoretical knowledge by improving the practice. The process was repeated during three consecutive semesters and reflection on the results which were achieved in each cycle helped enhancing the next one. As a result, a methodological procedure is proposed which consists of the definition of the Tridimensional Model as the integrating element for the contents studied in a specific academic period or semester. The teaching of Architectural Project as it is developed along the fifth academic period of the Architecture and Urbanism undergraduate program of UFRN is taken as a reference
