Waiting for the eggs to dance (and other tales from my grandmother's kitchen)
No full textWaiting for the Eggs to Dance, and Other Tales from my Grandmother’s Kitchen, is a novel/ recipe book written by Hong Yu Ran. The novel is based on the author’s grandmother’s life woven into a series of recipes that the author grew up with. Each recipe represents a different chapter in the author’s grandmother’s life from moving to Singapore from Hong Kong in the 1930s, surviving WWII and the Japanese occupation in the 1940s and the subsequent independence from the British Colony in the 1950s. The novel is written through the eyes and the taste buds of the author, remembering his childhood memories and uncovering his family’s history.Bachelor of Fine Art
Performance and security enhancement solutions for positron emission tomography medical hardware
No full textPositron Emission Tomography (PET) is an emerging medical imaging methodology for diagnosing cancer. The optimization and security solutions surrounding this technology are essential issues in biomedical engineering. Low-resolution and unauthorized modification of medical images will affect clinical analysis and medical diagnostics. To improve image quality and security while minimizing its impact on medical hardware, this paper analyzes a highly integrated data acquisition approach based on Time-over-Threshold (ToT) and proposes a lightweight security solution based on Physically Unclonable Function (PUF) for PET scan medical hardware. Compared to existing applications, the time-based sampling method can provide very good image quality, and the proposed watermarking and encryption method based on PUF enables enhanced privacy protection with fewer hardware costs for PET medical imaging technology

No full textPreparation of Yam Powders and Its Quality Change during Storage
No full text山藥分別以抗壞血酸，檸檬酸或亞硫酸氫鈉等溶液處理後，經冷凍乾燥、滾筒乾燥、熱風乾燥或日光乾燥製成粉末化製品，分析其物化性質，並以電子顯微照相觀察乾燥樣品，同時將製品儲藏於25℃下、5個月，分析其品質變化情形。試驗結果顯示原料山藥含有70~80％水份，16~21％醣，3~5％蛋白質及其他成份。冷凍乾燥法經0.5％檸檬酸及0.5％亞硫酸氫鈉液浸漬處理所製成之產品較其它乾燥法佳。製品經貯藏後，顏色及水份含量變化不大。
The procedure of preparing yam powders was developed and the changes in quality of the powder product during storage was also evaluated. Yam tubers were first treated, alone or in combination, with ascorbic acid, citric acid, and sodium bisulfite. The drying treatments included freeze drying, drum drying, air drying, and solar drying. The physicochemical properties were analyzed and scanning electron microscopy was evaluated on the powdered products. The powder was further stored at 25¢XC for 5 months and its physical properties was studied. The results indicated that the contents of water, carbohydrate, protein, and residual components of the raw yam material were, 70-80%, 16-21%, 3-5%, and 0-2%, respectively. The best powder product was obtained from 0.5% citric acid-0.5% sodium bisulfite pretreatment followed by freeze drying. Comparison between the freshly made and stored yam powder showed no significant difference in water content and color appearance
Isolation-Aware 5G RAN Slice Mapping over WDM Metro-Aggregation Networks
Full text linkTo accommodate the heterogeneous requirements of emerging 5G services, 5G Radio Access Network (RAN) will support the rising paradigm of network slicing, where a single physical RAN infrastructure is divided into multiple logical networks characterized by diverse requirements in terms of performance, cost, latency, and security, etc. The optimality of RAN slicing depends on various factors, such as slice requirements, resource availability and adopted network architecture. In 4G, RAN architecture evolved from a distributed architecture towards a 2-layer architecture that separates remote radio heads (RRHs) from baseband processing units (BBUs). However, this architecture has soon shown scalability limitations. To address this problem, the concept of flexible 5G functional split has been proposed, where RAN functions are distributed on a 3-layer architecture featuring a radio unit (RU), a distributed unit (DU), and a central unit (CU). Besides RAN architecture, isolation among different slices, which is necessary for slicing security, has a significant influence on the RAN slicing. In this work, we consider the isolation-aware RAN slice mapping problem considering advanced functional splits and a 3-layer RAN architecture. We propose a dual-objective heuristic algorithm for RAN slice mapping over a physical infrastructure represented by a wavelength division multiplexing (WDM) metro-aggregation networks. The proposed heuristic targets the minimization of 1) the number of active COs (i.e, hosting DUs and/or CUs) and 2) the number of established wavelength channels under constraints of network capacity and latency requirements. As our algorithm is also designed to map the RAN slices with least amount of physical resources for a given level of isolation, we also investigate the impact of slice isolation on resource utilization. Results show how higher isolation results in higher network cost
Extraction and Separation of lO-hydroxy-δ-decenoic acid from Royal Jelly by Supercritical Carbon Dioxide
No full text本研究之目的在於萃取與分離蜂王乳中葵烯酸（10-hydroxy-δ-decenoic acid ; 10-HDA ）成分。超臨界二氧化碳（supercritical carbon dioxide ; SC-CO2 ）是一種較其它溶劑（如水、乙醇、己院、乙醚、丙酮）安全、無毒、不易燃，而且萃取物與超臨界二氧化碳很容易利用降壓方式將其分離。葵烯酸是一種抗癌、抗氧化和抗菌之物質，食用後有強烈辛辣味，使得蜂王乳不易為消費者接受。為了提高產品接受性與價值性，此研究以超臨界二氧化碳為溶劑，萃取與分離蜂王乳中葵烯酸成分做為醫學用品，與去除不悅味道後之去葵烯酸蜂王乳產品做為食品、飲料與健康食品等用途。實驗操作選擇溫度40℃，壓力10 、20 、30MPa 與添加或不添加10 ％乙醇／蜂王乳（體積/重量比）當為輔溶劑等條件，求得最適溶解度（g 葵烯酸／g CO2）、分配係數（氣相與液相之溶解度比）與選擇性（葵烯酸與蜂王乳之分配係數比）。由實驗之最佳結果，採用溫度40℃ 、壓力25MPa 、添加10％乙醇之條件下，於連續式超臨界二氧化碳萃取系統進行實驗後，顯示此條件下可去除蜂王乳中之90％葵烯酸成分。
The objective of this study was to extract and separate lO-hydroxy- -decenoic acid (10-HDA) from royal jelly. A static and a continuous extraction methods using the solvent of supercritical carbon dioxide (SC-C02) or ethanol ¡Ò SC-CO2 were designed to rearch the objective and to measure the solubility of 10-HDA in SC-CO2 or in ethanol ¡Ò SC-CO2. The extraction were performed at 40¢XC and at pressures 10, 20, and 30 MPa. Results showed distribution coefficient of 10-HDA increased with pressure. Two products, 10-HDA and non- or low 10-HDA content of royal jelly products, were obtained at 25 MPa and 40¢XC in the ethanol + SC-CO2 continuous extraction system
