The evolution of the Han wedding dress design research and innovation / Gu Yanping and Rose Dahlina Rusli
No full textChina's long history has given birth to a colorful folk culture, and weddings are a significant part of life. The Chinese often use the term "married" to describe one's marital status, and wedding attire plays a crucial role in this cultural expression. Particularly in China’s dominant ethnic group, the Han, wedding dress traditions are something people pay great attention to. This article explores the evolution of Han wedding attire, detailing how it has changed since the Zhou Dynasty, up through the reforms and opening to the outside world. Throughout the dynasties, Han wedding dresses have exhibited unique characteristics and differences. With the economic, political, and cultural developments during the early Republic era, the grand and solemn traditional wedding dress gradually became westernized. However, Han Chinese traditional wedding attire remains a living cultural symbol, embodying the unique, beautiful, and mysterious essence of ancient Oriental culture, and representing the Han nationality. In designing modern Han wedding dresses, it is important to create designs that are aligned with contemporary trends while preserving the distinct characteristics of Han culture. By incorporating elements from different dynasties, such as traditional patterns, colors, fabrics, and shapes, alongside modern techniques and some western influences, innovation in Han wedding dress design can be achieved. Furthermore, through combining this research with personal innovation design practices, we can continue to inherit and carry forward the tradition of Han wedding attire, making a lasting contribution to its preservation
Identifications of polyphenols and quantification of anthocyanidins in grapes and grape-derived products
No full textPolyphenols in grapes and grape-derived products have attracted public and scientific attention due to their numerous protective roles to human health. A rapid and comprehensive qualitative method was developed to characterize the different classes of polyphenols, such as anthocyanins, flavonols, phenolic acids and flavanols/proanthocyanidins, in grapes and grape-derived products. The detection was achieved by two runs with same HPLC gradient in different MS ionization modes and mobile phase modifiers (positive mode and 0.4% trifluoroacetic acid for anthocyanins and flavonols, negative mode and 0.1% formic acid for phenolic acids and flavanols). Under the optimized LC/MS conditions and based on the analysis of the MS and UV data and in comparison with the authenticated standards, a total of 53 polyphenolic compounds were successfully separated and individually identified including 33 anthocyanins, 12 flavonols, 4 phenolic acids and 4 flavanols/proanthocyanidins. With the method developed, a survey was conducted to qualitatively assess and compare the composition of polyphenols among 29 grapes and grape-derived products. To facilitate the quantitation of the major class of polyphenolic anthocyanidins, a simple and precise acid assisted hydrolysis method was established for the quantitation of anthocyanidins in grape juice samples, grape berries and grape skins using LC/MS. Five most common anthocyanidins of delphenidin, petunidin, cyanidin, malvidin, and peonidin in the hydrolyzed grape extracts were included in the quantification study. The validation of this method showed that the recovery percentages of five anthocyanidins ranged from 98.59 % to 103.20% with the relative standard deviation (RSD) less than 5.03%. The qualitative method provided complete insight into the composition of polyphenols in grapes, and other grape-derived products. This quantitative method provides a rapid and accurate tool to quantitatively study individual anthocyanidin in grapes or grape juice samples for quality control and to facilitate the evaluation and comparison of new commercial grapes or grape juice products in market.M.S.Includes bibliographical referencesby Yanping X

CRM and its various modified versions have achieved great successes in finding the maximum tolerated dose (MTD) adaptively in the case of dichotomous toxicity responses (i.e. dose-limiting toxicity, DLT, or non-DLT). In dose-escalation processes, it is crucial to differentiate severity of DLT if the impact of severity of toxicity is substantial (e.g. liver toxicities). However, due to the limitation of its model structure, it is difficult to extend CRM naturally to the polychotomous toxicity responses.
In this research, we propose a two-parameter probit model with latent variables to extend the CRM for the cases of dichotomous and polychotomouse toxicity responses. For the dichotomous toxicity responses, simulation results under different scenarios show that the proposed model is superior to the power model originally used in the CRM. We extend the proposed model naturally to the ploychotomous toxicity responses by categorizing the latent variables corresponding to the bin boundary parameters. Simulation results show that two-parameter probit model with latent variables works encouragingly well in the case of polychotomous toxicity responses. By differentiating severity of DLT, the number of patients allocated to the higher toxicity dose level is reduced. That reduces the risk of toxicity for patients in the clinical trial study.
In addition, we introduce the concept of the overall MTD which makes it possible to study both dichotomous and polychotomous response models under a unified framework. Analytic properties of the overall MTD are given. It is shown that dichotomous response model is a special case of polychotomous response model and under certain circumstances the polychotomous response model is reduced to dichotomous responses model.
Furthermore, we generalize the concept of the overall MTD to a more broader case. Under this concept, a unified model is built, which includes categorical (such as dichotomous and polychotomous) and numerical (such as continuous) toxicity responses as its special cases. The Convergence, Robustness and Reduction theorems of the overall MTD are proved in the general case. As an example of the continuous toxicity response, the normal toxicity response is studied along with a family of the target toxicity probabilities.Management Science and Statistic
Edge-unfolding almost-flat convex polyhedral terrains
No full textThesis (M. Eng.)--Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2013.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 97-98).In this thesis we consider the centuries-old question of edge-unfolding convex polyhedra, focusing specifically on edge-unfoldability of convex polyhedral terrain which are "almost at" in that they have very small height. We demonstrate how to determine whether cut-trees of such almost-at terrains unfold and prove that, in this context, any partial cut-tree which unfolds without overlap and "opens" at a root edge can be locally extended by a neighboring edge of this root edge. We show that, for certain (but not all) planar graphs G, there are cut-trees which unfold for all almost-at terrains whose planar projection is G. We also demonstrate a non-cut-tree-based method of unfolding which relies on "slice" operations to build an unfolding of a complicated terrain from a known unfolding of a simpler terrain. Finally, we describe several heuristics for generating cut-forests and provide some computational results of such heuristics on unfolding almost-at convex polyhedral terrains.by Yanping Chen.M.Eng
Who Is the Real Tycoon? (Review)
No full textReview of "Who Is the Real Tycoon?" and short bio of director Kevin Chu (Chu Yen-ping/Zhu Yanping). A hilarious and straightforward slapstick comedy packed with numerous physical routines and outrageous cat-and-mouse set-ups, "Who Is the Real Tycoon?" features Taiwan's legendary comedian Hsu Pu-liao (Xu Buliao) in his prime playing two brothers of opposite social classes. The lowbrow film serves as a distinctive manifestation of the Chu and Hsu phenomenon that swept the Taiwanese audience off their feet laughing in the early 1980s
Optimisation of Reverts Usage on Sintering Processes and Impact on the Sinter Quality: An experimental study into the mechanisms of sintering processes and production by utilising additives
No full textUtilisation of reverts in sinter production is nonetheless challenging considering physical and chemical characteristics: physical by means of presence of extreme amount of fine material (<1mm) and chemical in terms of heavy metals, alkalis and uneven distribution of materials. Poor granulation, affecting permeability and degrading of cold strength of produced sinter are negatively influencing sinter processes. On the other hand, reverts contain valuable materials as carbon- and iron-bearing materials, and can affect the sinter process positively. Steelmaking companies generate large quantities of reverts, however the impact of reverts on sinter processes and sinter quality is not fully investigated. With this in mind, this study investigates the impact of revert blends utilised in sinter blend on sinter processes and quality.Only abstract due to embarg
