Stripes - An exploration of hand weaving and accessory design

The thesis examines questions aroused by a trip to China in spring 2019, is everything going too fast? Should we slow down a bit? During this trip, I saw the fast urbanization city scene and the fast-produced products in local shops. On the contrary, I also encountered the peaceful Chinese gardens and the local handwoven fabrics. These local crafts resonate with my previous experience working for a luxury brand, which focuses on craftsmanship in design. This project explores the responsibility and role of a designer in this fast world, and hopefully, the questions, “Is everything going too fast? Should we slow down a bit?”, would be answered through the process. The final results of the project are a woven textile collection and an accessory collection where tex-tiles are applied. For the textile collection, the research question is, how to design a woven textile collection that reflects the traditional Chinese garden scene. Furthermore, handweaving techniques and striped fabrics are explored. The accessory collection researches how to apply the woven textile to everyday life products, reflecting the contrasting life between the fast urbanized city and the traditional Chinese garden, encouraging people to reconsider the speed of current life. The following research methods are used: literature review, field trip and prototyping. The study on the hand weaving technique, the striped textile history and the Chinese garden history are conducted through literature review. The Chinese garden scene is observed and researched through field trips. The final textile and accessory collection are achieved by prototyping. The final results demonstrate one example of reflecting the Chinese garden scene through the woven textile, tackling the contrasting fast urbanization phenomenon through the accessories. It also shows one possibility of combing hand weaving with accessory design, bringing traditional crafts to current everyday life. Hand weaving could be one way of slowing down our fast life

Magnetostriction and Magnetic Anisotropy of Fe35Co65

A Fe35Co65 single crystal has been prepared by a long time anneal at temperature close to its fcc-bcc phase boundary. Its magnetostriction constant ë100 and magnetocrystalline anisotropy constant K1 was measured using a strain gauge rosette and magnetization and torque magnetometer curves. The magnetostriction constant ë100 is as high as 200 ppm. The value of the anisotropy constant K1 and the value of the susceptibility were small and influenced by the magnetoelastic energy. The symmetry of the torque curves changes from 2-fold to 4-fold with increasing external field which indicates the existence of a second uniaxial phase. This result can be interpreted by the alignment of the magnetization of an epitaxial fcc precipitate in the bcc host by external field

Temperature enhanced effects of ozone on cardiovascular mortality in 95 large US communities, 1987-2000 - assessment using the NMMAPS data

A few studies examined interactive effects between air pollution and temperature on health outcomes. This study is to examine if temperature modified effects of ozone and cardiovascular mortality in 95 large US cities. A nonparametric and a parametric regression models were separately used to explore interactive effects of temperature and ozone on cardiovascular mortality during May and October, 1987-2000. A Bayesian meta-analysis was used to pool estimates. Both models illustrate that temperature enhanced the ozone effects on mortality in the northern region, but obviously in the southern region. A 10-ppb increment in ozone was associated with 0.41 % (95% posterior interval (PI): -0.19 %, 0.93 %), 0.27 % (95% PI: -0.44 %, 0.87 %) and 1.68 % (95% PI: 0.07 %, 3.26 %) increases in daily cardiovascular mortality corresponding to low, moderate and high levels of temperature, respectively. We concluded that temperature modified effects of ozone, particularly in the northern region

Detectable MeV neutrinos from black hole neutrino-dominated accretion flows

Neutrino-dominated accretion flows (NDAFs) around rotating stellar-mass black holes (BHs) have been theorized as the central engine of relativistic jets launched in massive star core collapse events or compact star mergers. In this work, we calculate the electron neutrino/anti-neutrino spectra of NDAFs by fully taking into account the general relativistic effects, and investigate the effects of viewing angle, BH spin, and mass accretion rate on the results. We show that even though a typical NDAF has a neutrino luminosity lower than that of a typical supernova (SN), it can reach $10^{50}-10^{51}~{\rm erg~s^{-1}}$ peaking at $\sim 10$ MeV, making them potentially detectable with the upcoming sensitive MeV neutrino detectors if they are close enough to Earth. Based on the observed GRB event rate in the local universe and requiring that at least 3 neutrinos are detected to claim a detection, we estimate a detection rate up to $\sim$ (0.10-0.25) per century for GRB-related NDAFs by the Hyper-Kamiokande (Hyper-K) detector if one neglects neutrino oscillation. If one assumes that all Type Ib/c SNe have an engine-driven NDAF, the Hyper-K detection rate would be $\sim$ (1-3) per century. By considering neutrino oscillations, the detection rate may decrease by a factor of 2-3. Detecting one such event would establish the observational evidence of NDAFs in the universe.Comment: 7 pages, 2 figures, 2 tables, accepted for publication in PR
