Methodological Innovation in Practice-Based Design Doctorates
No full textThis article presents a selective review of recent design PhDs that identify and analyse the methodological innovation that is occurring in the field, in order to inform future provision of research training. Six recently completed design PhDs are used to highlight possible philosophical and practical models that can be adopted by future PhD students in design. Four characteristics were found in design PhD methodology: innovations in the format and structure of the thesis, a pick-and-mix approach to research design, situating practice in the inquiry, and the validation of visual analysis. The article concludes by offering suggestions on how research training can be improved. By being aware of recent methodological innovations in the field, design educators will be better informed when developing resources for future design doctoral candidates and assisting supervision teams in developing a more informed and flexible approach to practice-based research

Thieo Chiangsaen yon adit dindaen sut Lanna
No full textIn this article, the author describes the history of Chiangsaen, an important ancient city in northern Thailand. It was once the center of the Lanna Kingdom but it has now become a district in Chiangrai province. The school of Chiangsaen was famous for its unique and exquisite artistic style in Buddhist art and sculpture. The author also suggests several historical places in Chiangsaen where visitors should not miss. This includes Buddhist temples and shrines, and museums
A Requiem For Those Who Rest Their Wings
No full text\u27A Requiem For Those Who Rest Their Wings\u27 is a piece that emphasizes how nerve-wracking it is to leave your safe space and pursue your dreams. The author behind this piece has many dreams that require them to face their anxiety and present themselves to the world. The piece was especially inspired by the author\u27s enjoyment of Japanese music, particularly the song \u27Little Bird\u27 by Chiaki Ishikawa
Pattani adit anachak Lankasuka an yingyong
No full textThe article features the history of Pattani, one of Thailand's four southern-most provinces. Nowadays Pattani is well-known for its unique Muslim culture, with its people speaking Malay more often than Thai which is the official language. The author reports on the archaeological and historical evidence, which supports the argument that Pattani used to be a prosperous trade center in this region

Metal mobilization and zinc-rich circumneutral mine drainage from the abandoned mining area of Osor (Girona, NE Spain)
No full textThis is a copy of the author 's final draft version of an article published in the journal Mine water and environment.

http://dx.doi.org/10.1007/s10230-015-0344-6Contaminated soil and mine wastes in Spain’s abandoned Osor mining area contain Cd, Co, Pb, Zn, As, Ba, and Sb at levels that exceed Catalonia’s regulatory limits for soils of industrial use. Mine water from the Coral adit, which is the main dewatering system in the Osor area, has circumneutral pH from carbonate and silicate dissolution, and high concentrations of Fe, Mn, Ni, Pb, and Zn. Geochemical modeling showed that smithsonite and hydrozincite were possible solid phases for Zn. The Coral adit is the main source of contaminants to Osor Creek, especially Zn and SO 4 -2 .Peer Reviewe

Tam roi Phranang Luat Khao yon adit su muang Trang
No full textThe author narrates the tale concerning Phranang Luat Khao. The story of Phranang Luat Khao is recounted in many southern provinces, including Phatthalung and Trang. According to the story, Phranang Luat Khao and her husband, Phraya Kuman, were the great patronages of Buddhism. People believed that they built a number of Buddhist temples and Buddha statues in the Southern region, especially in Trang province
Degradation Linearity Determination and Temperature of Soiled Photovoltaic Modules in the Field
No full textabstract: Photovoltaic modules degrade in the field. This thesis aims to answer two questions: 1. Do photovoltaic modules degrade linearly or not? 2. Do soiled modules operate at lower temperatures than clean modules? Answers to these questions are provided in part 1 and part 2 of this thesis respectively.
Part 1: Linearity determination in degradation: The electricity output from PV power plants degrades every year. Generally, a system’s life is considered to last for 20-25 years and rate of degradation is commonly assumed as 1% per year. PV degradation can be found out using Performance Ratio (PR), Performance Index (PI) and raw kWh output. The rate of degradation is considered linear for simplicity of calculations. In this thesis, statistical methods are used to check whether systems in Arizona are degrading linearly or not. Time series modeling such as Winters’ method and ARIMA are used to model the data. Winters’ method and Seasonal ARIMA consider the seasonality component and perform well for small data sets of about 10 years. Rate of degradation is found out as linear for all the evaluated systems.
Part 2: Temperature analysis of clean and soiled modules: Soiling and temperature are important parameters in performance of PV modules. In this paper, an analysis is carried out on a soiling station located in Mesa, Arizona. The soiling station consists of 10 different c-Si coupons with tilt angles varying from 0° to 45° with the difference of 5°. These coupons are cut in half, one is cleaned periodically and the other is remained soiled naturally. The analysis involves data worth for 19 months. 6 dry spells in all four seasons within 19 months were analyzed. The temperature difference between a clean module and a soiled module (ΔT) is compared with the soiling loss factor (SLF). The analysis concludes stating in which season a soiled module is hotter or cooler than a clean module.Dissertation/ThesisMasters Thesis Mechanical Engineering 201
