Into The Kesi Story: Textile Design Practice of Kesi Weaving in Contemporary Context
(2016) Huang, Yi
School of Arts, Design and Architecture | Master's thesis
Kesi is a specific name in Chinese refers to the Chinese silk tapestry. It is a traditional hand woven technique which nowadays mainly exists in Suzhou area. Like the circumstances of many other traditional handicrafts in China, Kesi weaving in Suzhou is facing the rapid declining in these decades. The thesis work is based on the collaborative project with a local start-up brand DAJIE that concentrates on the new design practice especially with the applying of Kesi weaving. The thesis depicts the way to understand the situation and possibilities of Kesi weaving in contemporary context and discuss the utilization of such cognition in the real design practice. Initiating from the background research of Kesi weaving, a comprehensive knowledge of Kesi textile is introduced through the different aspects like historical development, technique features and the regional crafts culture. With the understanding of Kesi weaving, the current situation of local Kesi industry is then investigated via the workshop visiting and the interviews with representative Kesi masters. The research provides a reference which helps to realize and comprehend the problems in the current mode of Kesi industry. By analyzing and learning from the existing cases of contemporary design practices, new perspectives are provided to think about the probability of new product development linked with contemporary life and modifying the traditional handicrafts through new design methods. And to connect the Kesi traditions with the platform of a brand is considered as a preferable way to raise the accessibility of Kesi textile to the contemporary world. The creative design development with realizing the factors of brand and commerciality is the key focus during the actual design practice at the next stage. An agreed collection of Kesi textile products for DAJIE has been described specifically from concept to final products, including the development of colorways, material choice, surface and structure testing. The role of the designer has been highlighted in the design process for properly balancing the design expression and the commerciality as well as transforming the traditional aesthetics to meet the contemporary tastes. However, to communicate and lead the traditional craftsmen to accept the new changes is another challenge for a designer in the production. Thus, an efficient way of communication between the Kesi weavers and the designer is necessary in regard to the different situations. The final result of the project includes the textile decoration products and the textile accessories for the DAJIE collection. The project provides an angle to see the traditional Kesi weaving through the perspective of textile design in contemporary context. As a case study in protecting and developing the local Kesi weaving technique, this thesis would also be a starting opportunity for the future developing of Kesi weaving.
Outdoor Signal Strength Measurement at TV Band and ISM Band in Otaniemi Campus
(2013-09-23) Huang, Yi
Sähkötekniikan korkeakoulu | Master's thesis
TV white space technology is being intensively researched as it offers a solution that allows secondary usage of the local unused TV channels on a non-interfering basis to achieve a high spectrum efficiency. This thesis studies the difference between TV band and ISM band outdoor propagation characteristics in Otaniemi campus area. The study aims to verify if the TV band signal could extend the service range with less transmitting power and if it has better propagation and building penetration characteristics than ISM band signal. As part of our research we first perform a state-of-the-art review on TV white space technology including its features, promising applications and the evolution of regulation and standardisation. Then the measurement campaign set up is demonstrated based on the architecture of transmitter and receiver, the signal source and the antenna. Measurements were carried out by two transmitter locations and 49 receiver locations over distances up to 2.6 kilometers. The 'tcpdump' tool in OpenWrt system that embedded in Dlink box was used to measure the received signal characteristics for both bands. The measurement results have been compared with the existing empirical propagation models and the differences between the model predicted and field measured data have been analysed. The results could be considered as a good basis for further theoretical research as well as for practical application research.
