Hannes Beckmann (1909-1977). Dessau - Prague - New York This PhD thesis is dedicated to an exceptional, though still forgotten personality, an artist of German descent, Hannes Beckmann |1909-1977|. A graduate of Germany's Bauhaus, he was one of the refugees fleeing Nazism to Czechoslovakia, and among many other achievements, he later became the director of the photography department of the Guggenheim Museum in New York. Through his work, he fulfilled avant-garde ideas on the synthesis of artistic fields: he was a painter, stage designer, art theorist and pedagogue, but also a creator of abstract objects moving along the boundaries of minimalistic and kinetic constructions. His fate in life and created body of work began gaining a clearer form in the framework of research on visual artists, who found sanctuary in interwar Czechoslovakia from demagogic political systems. Until that time, Hannes Beckmann had been utterly unknown to Czech art history and elsewhere. This is seen in the absence of his name in Czech technical literature, but also because he was never mentioned even in publications published by the Bauhaus with which he had been involved for some time. There was only sketchy information on his pedagogical and artistic work in the area of Op-Art (optical art) from the 1960s to 1970s in the United...

In Sweden upper secondary school education is organised in programmes. One of these programmes is the Technology programme that covers five orientations, one of which is Design and Product Development. This thesis is based on the idea that a clearer link between upper secondary school and the demands of professional life in the area of product development is beneficial to both students and industry. Product development is performed in cross-functional teams were understanding of others competences is important. It is therefore argued that, in order to enhance both teaching and learning, interdisciplinary considerations need to be explored. In this thesis, we turn to engineers and industrial designers. The aim of the present study is to get professional actors’ views on knowledge and skills needed within the field of design and product development and to examine whether there are key areas that facilitate an interdisciplinary approach suitable to focus on for educational purpose. As artefacts play a central role in product development the informants’ views on different products/artefacts are also examined. This reasoning results in an a two-part overall research question (a) What thoughts do professional engineers and industrial designers express regarding necessary knowledge and skills, and (b) what relevance does this have for upper secondary school teaching of product development? This overall research question is examined through two sub- studies, both performed at the same time, one conducted as a semi- structured interview and the other using the repertory grid technique. Twelve engineers and industrial designers are interviewed. The first study examines the informants’ thoughts on knowledge and skills required in their work. The same informants’ interpretations and valuations of artefacts are examined in the second sub-study. In sub-study 1 two topics of significance to the informants are identified. These topics are: [1] To act within the team (Figure 4). The ability to navigate and position oneself within a team is, according to the interviewees, a necessary skill in design and product development work. Its character can be described as including specific vocational knowledge and skills as well as issues of general and interdisciplinary nature as collaborating, compromising, communicating, and leadership. The second topic [2], to CAD (Figure 4) includes both skills with CAD software and the ability to understand relationships between a CAD model on screen and the final product. The third topic [3] - a valuation of artefacts - is the outcome of sub- study 2 (Figure 4). This topic was found interesting and further analysed, resulting in the development of a comparison procedure. The result demonstrates how the interviewees interpret and discuss artefacts’ functionality linked to cultural values. These three topics are found to be relevant for technology education at upper secondary school level geared towards design and product development to explore. To act within the team can inspire the development of activities in which project and teamwork are in focus. The purpose of the CAD model in product development is to visualise a product that does not yet exist. To CAD highlights the complexity of this visualisation ability. In the educational context the students can train this ability by developing digital models into physical models or prototypes. Valuations of artefacts, the interviewees associate artefacts’ functionality with certain characteristics. In education students should learn that we are not neutral in our relations to products and other artefacts. In conclusion, a need for teachers to discuss artefacts from different perspectives such as sustainability, usability, identity and so on is also pointed out. / <p>QC 20150212</p>

The lack of synergy between design and marketing departments can result in less innovative products which can lead to less customer satisfaction. This problem has affected the perfume and cosmetic industry as well, which is considered to be an industry with high competitiveness but also a high innovation rate. The purpose with this study is to understand how consumers' purchase intention can be affected by the characteristics that appear in each collaboration pattern, marketing lead, design lead and co-branding, in order to contribute to a more effective cooperation between external design and marketing in the perfume and cosmetic industry. The study has been based on two theories and one previous research. The theories are Kellers (1993) Consumer Based Brand Equity and Arnoulds and Thompsons (2005) Consumer Identity Project based on the Consumer Culture Theory. The previous research on which this study is based is Hemonnet-Goujots Abecassis-Moedas' &amp; Manceaus (2020) “When external design and marketing collaborate to develop new products: A typology of patterns”. The study has been based on a qualitative research method with a deductive and a hermeneutic approach. The results showed that consumers' purchase intention is affected by brand recognition in products with a high brand consistency. In addition, consumers can be affected by the brand image and the non-product-related attributes together with the symbolic benefits of products with a high rate of innovation and thus of products where a star-based designer is involved. The Consumer's Identity Project is something that always affects the purchase intention, regardless of the characteristics of the product. The information that the study contributes with can be used by companies with external design and marketing in a strategic way to choose which collaboration pattern they want to work with. / Bristen på synergi mellan design och marknadsföring kan resultera i mindre innovativa produkter, som i sin tur leder till mindre kundnöjdhet. Denna problematik har inte minst påverkat parfym- och kosmetikabranschen som anses vara en bransch med hög konkurrenskraft och med hög innovationstakt. Syftet med studien är att förstå hur konsumenternas köpintention kan påverkas av kännetecken som förekommer i respektive samarbetsmönster, marketing lead, design lead och co-branding. Detta för att bidra till ett mer effektivt samarbete mellan extern design och marknadsföring. Studien har utgått från två teorier och en tidigare forskning. Teorierna är Kellers (1993) kundbaserat varumärkeskapital (Costumer Based Brand Equity) och Arnould &amp; Thompsons (2005) konsuments identitetsprojekt (Consumer Identity Project) utifrån konsumentkulturteorin (Consumer Culture Theory). Den tidigare forskningen som denna studie har grundat sig på är Hemonnet-Goujots, Abecassis-Moedas &amp; Manceaus (2020) “When external design and marketing collaborate to develop new products: A typology of patterns”. Studien har utgått från en kvalitativ forskningsmetod med en deduktiv ansats samt ett hermeneutiskt synsätt. Resultatet visade att konsumenternas köpintention påverkas av varumärkesigenkänning vid produkter med en hög varumärkeskonsistens. Därtill kan konsumenter påverkas av varumärkesbild och de icke-produktrelaterade attributen i samband med de symboliska fördelarna vid produkter med en hög innovationstakt och därmed vid produkter där en stjärndesigner är inblandad. Konsumentens identitetsprojekt är något som alltid påverkar köpintentionen oberoende på vilka kännetecken produkten förekommer med. Informationen som studien bidrar med kan utnyttjas av företag med extern design och marknadsföring för att på ett strategiskt sätt välja vilket samarbetsmönster de vill arbeta med.

Automatisering av testprocesser är viktigt eftersom manuella tester är komplicerade och tidskrävande. Testarbetet effektiviseras och kvaliteten kan höjas genom att automatisera testprocesserna. Arbetet som beskrivs i det här examensarbetet har utförts på Phoniro AB i Halmstad och syftet med projektet är att identifiera och konstruera en helautomatiserad lösning för skanningen av NFC-taggar och QR-koder. I arbetet konstrueras en mekanisk testrigg som är en lämplig lösning baserat på framtagna krav. För att välja den mest lämpliga mjukvaru- och hårdvaruplattformen för testriggen utifrån kraven användes utvärderingsmatriser. Testriggen består av tre delar, en 3D-modell av testriggen, ett kretskort som är testriggens kontroller och mjukvarudel för att programmera testriggen och integrera den med företagets testramverk. Därefter har testriggen byggts upp, alla delar kopplats ihop och programmerats för att testas mot de krav som ställts upp. Testriggen som har tagits fram är en prototyp som har en stor utvecklingspotential med tanke på framtida utveckling / Automation of test processes is essential because manual tests are complicated and time-consuming.

A short film about how to design informality in the city. By comparing the chaotic Lagos with the orderly Stockholm the film rethinks the role of the designer and shows that planning as a sphere of building consistently destroys lived space. It illuminates the tension between the orderly and the chaotic, the ideal and reality.

在國際時尚舞台中，台灣在過去一直扮演代工的角色：儘管手中握有無與倫比的研發與生產技術，然而報酬率卻遠不及握有「國際品牌」的廠商。 1990年起，台灣以往勞力、技術密集的紡織產業開始走下坡。台灣紡織產業開始面臨勞工短缺、工資上漲，許多低價紡織品在國內生產已無獲利空間；從2000年左右開始，隨著全球化市場發展，中國大陸與東南亞等新興國家陸續崛起，我國紡織產業開始產生外移。2005年，WTO協定生效，取消「紡織貿易配額」，以及全球各地逐漸形成的「區域經濟體」，使得全球紡織產業發生結構性的變化。 近來「美學經濟」指標性產業：「時尚產業」，已經成為亞洲國家積極發展的目標，而政府也大力鼓吹由過去專業代工的「製造經濟」，轉型為以品牌、設計為主的「創意、知識經濟」。2008年國家重點發展計畫中提出「產業高值化」政策，除了研發，強化行銷能力以提升品牌知名度亦是創造高附加價值的重要關鍵。 台灣在本土時裝設計師品牌不少。然而，礙於台灣市場規模，始終無法有大幅的成長。因此，台灣設計師如何進軍國際市場，便成了一個值得深入探討的議題。 本研究結合Csikezentmihalyi創造力系統模式、與設計師日常事業經營，探討本土設計師時裝品牌國際化的動態過程：設計師如何以服裝設計專業、結合創業營運相關知識，不斷與國際時尚界專業人士與買家們溝通互動，進而使其品牌在國際間佔有一席之地。 本研究同時歸納設計師在進軍國際市場時需要哪些能力，以及在進入國際市場不同階段所應注意的管理議題，期望能供業界、後續學術研究參考、指教。 / This research is about how Taiwanese fashion designers market their products internationally. Taiwanese textile companies didn’t have their own brands before. They mainly manufactured and sold products overseas under foreign brand names. However, the textile manufacturing industry in Taiwan has already moved abroad to low-labor-cost area during the past two decades. Taiwanese designer brands have been struggleing between the small domestic market and the competition of foreign brands. I explored three cases of Taiwanese fashion designers who market their brands and products internationally. They are respectively Hong, Li Fen’s designer brand ‘Sophie Hong’, Chien, Yu Feng and Pan, Po Shun’s ‘Shawnyï’, and Chia, Wen Lan’s ‘Twinkle by Wenlan’. I analyzed these cases based on the Creativity Dynamic System Model (Csikezentmihalyi, 1990). First, I discovered how they combine their expertises of fashion design and business management to organize their international network. Second, the abilities a fashion designer has to possess during his way to international fashion market have already been clearly listed and categorized. In the end, I casted several managerial issues the fellow designers should pay attention to in different stages when they try to internationalize their brands and products.

This thesis primarily deals with the concept of designing an antenna based device to harvest energy from Radio Frequency (RF) and using the harvested energy to sense the available Long Term Evolution (LTE) network in order for the Internet of Things (IoT) devices to connect to the network for the purpose of transmitting and receiving data. Secondarily the importance of this project is targeting how to conserve battery power in an IoT device and extend it’s lifetime. Research in the field of energy harvesting has been going on for a long time. Most of the researches concentrate on harvesting significant amount of energy to power up an entire device and so no one has ever thought of using the harvested RF energy to sense the availability of LTE network. This method of using antenna to sense network requires only a small amount of harvested energy. Due to this reason the proposed design works for a very low input received signal strength indicator (RSSI) as well, unlike higer RSSI required for other applications. The proposed design has three major sub-parts such as the (i) Antenna for the purpose of receiving the available ambient radio frequency. (ii) Matching circuit for the purpose of maximum power transfer between the antenna and the rectifier circuit. Finally (iii) rectifier which is used to convert the AC voltage into DC voltage. The device then measures the obtained voltage through the Analog to Digital Converter (ADC) pin in the Micro-Controlling Unit (MCU) available with the attached IoT device. The MCU then maps the harvested voltage into the corresponding analog voltage.Depending on the set threshold voltage the MCU can then advice whether or not to connect to the LTE network. The design implements matching circuit for the two LTE bands that are primarily in use in the European region i.e., band 3, 8 that work in 915, 1800 MHz frequency region respectively. In this way we can identify in which band the device is harvesting energy. The matching circuit also acts as a bandpass filter. For the design and production of the entire harvester device one needs adequate knowledge in the field of RF and Antennas and a high level knowledge in the field of electronics in order to run Simulations and to design Printed Circuit Boards (PCBs). Advanced Design Software (ADS) has been used to run all the simulations and Altium software for the design of PCBs. The final prototype is presented along with the casing and tested on the field in practical scenario. Antenna test chambers were used to test the performance of the antennas being used for the design. The prototype harvests RF energy and indicates whether or not to connect to the LTE network with the help of light emitting diode (LED). The uniqueness of the device is that it can detect signals as low as -110 dBm, this has been set as the threshold for the purpose of sensing LTE networks. / Denna avhandling behandlar primärt konceptet att använda antenner för att hämta energi från RF och att använda den insamlade energin för att känna av det tillgängliga LTE-nätverket för att IoT-enheterna ska kunna ansluta till nätverket för syftet med att överföra och ta emot data. Sekundärt Målet med av detta projekt är att spara batteri i en IoT-enhet och förlänga dess livslängd. Forskning inom området energiskörd har pågått under lång tid nu. De flesta av undersökningarna koncentrerar sig på att skörda betydande mängder energi för att driva en hel enhet och så ingen har någonsin tänkt på att använda den avkända RF-energin för att känna av tillgängligheten för LTE-nätverket. Denna metod för att använda antenn för att känna av nätverk kräver endast en liten mängd skördad energi. På grund av denna anledning fungerar den föreslagna designen även för en mycket låg ingång RSSI, till skillnad från högre RSSI som krävs för andra applikationer. Den föreslagna designen har tre huvuddelar, såsom (i) antennen för att ta emot den tillgängliga omgivande radiofrekvensen. (ii) Matchningskrets för maximal effektöverföring mellan antennen och likriktarkretsen. Slutligen (iii) likriktaren som används för att omvandla AC-spänningen till DC-spänning. Enheten mäter sedan den erhållna spänningen genom ADC-stiftet i MCU som finns tillgänglig med den anslutna IoT-enheten. MCU mappar sedan den genererade spänningen till motsvarande analoga spänning. Beroende på den inställda tröskelspänningen kan MCU sedan ge råd om att ansluta till LTE-nätverket eller inte. Konstruktionen implementerar matchningskrets för de två LTE-banden som primärt används i den europeiska regionen vilka är band 3, 7 som arbetar i 915 respektive 1800 MHz frekvensområdet. På så sätt kan vi identifiera i vilket band enheten hämtar energi i. Matchningskretsen fungerar också som ett bandpassfilter. För design och produktion av hela insamlingsenheten behöver man adekvat kunskap inom området RF och antenner och en hög nivå kunskap inom elektronikområdet för att kunna köra simuleringar och designa PCBs.ADS har använts för att köra alla simuleringar och Altium-mjukvara för design av PCBs. Den slutliga prototypen presenteras tillsammans med höljet och testas på fältet i praktiskt scenario. Antenntestkammare användes för att testa prestandan hos antennerna som användes för konstruktionen. Prototypen skördar RF-energi och indikerar om man ska ansluta till LTE-nätverket eller inte med hjälp av blinkande LED.Det unika med enheten är att den kan upptäcka signaler så låga som - 110 dBm, detta har satts som tröskel för avkänning LTE nätverk.
