3D reconstruction of cloud cells
No full textGround-based sky cameras are increasingly used now-a-days to understand cloud formation analysis in the atmosphere. Such cloud analysis has varied applications in aviation industry, solar and renewable energy predictions and cloud attenuation analysis. In this report, the author is interested to perform a 3D cloud reconstruction using a pair of ground-based sky cameras. Conventional feature matching approaches in computer vision community could not be directly applied to atmospheric clouds, which often seen as featureless, and that may pose as a challenge in such computer vision analysis. This project aims to identify the most effective feature matching algorithm that could maximise the performance of 3D cloud cells reconstruction. Also, parameters which affect the respective feature matching algorithm performances would be covered. Putting particular focus on various types of clouds, in order to improve the feature point matching performance and efficiency, experimental results on cumulus and dark stratocumulus clouds have reflected that the proposed algorithm of combining SURF feature point matching and adaptive histogram equalization contrast technique, have resulted in stronger robustness in a variety of complex image cases, such as dark clouds and stratocumulus clouds for 3D cloud cell reconstruction.Bachelor of Engineerin
Domain knowledge inspired deep learning: from general AI to specialized AI
No full textDeep learning has achieved remarkable success in various areas such as predicting protein structure, defeating human on Go, assisting disaster recovery with deep robotics, enabling smart trading with deep time serials model. With its robust prediction capabilities and modeling prowess, deep learning has also begun to excel in complex domains like talent management and business. Due to the presence of more ``human factors'', these domains are generally regarded as more intricate. However, three limitations largely impede the development of DL models in these domains, that is, (1) label intensive, (2) poor interpretability, and (3) hard to adapt. This paper aims to enhance current deep learning models in the management and business domains with human domain knowledge. Specifically, for the label intensive issue, we can leverage graph-structured knowledge such as knowledge graph to augment data labels. For the domain adapting issue, the bottleneck is to understand domain phrases and we can encode more semantic knowledge to mitigate this. Lastly, theory knowledge can help with explaining model predictions. However, these knowledge are in very different forms and the key difficulty is how to effectively leverage them. We proposed three techniques accordingly to apply the knowledge in deep learning frameworks. In the first essay, we propose a structure-aware augmentation method that can leverage graph knowledge for data augmentation. In the second essay, we propose a network conceptualizing method, which can leverage theory knowledge to help make sense of neural network internals. In the third essay, we propose a representation learning and pre-training approach to encode semantic knowledge to enhance the domain adaptation ability of deep models. We show promising results of the proposed three approaches in three applications, namely, Job Title Benchmarking, Employee Turnover Prediction, and E-commerce Review Understanding. Each of the applications possesses rich and distinctive domain knowledge. Ultimately, using this domain knowledge inspired framework, we aim to build more label-efficient, domain-oriented, and interpretable AI.Ph.D.Includes bibliographical reference

No full textPh.D.BackgroundColorectal cancer (CRC) is the third most common cancer worldwide in 2018. After surgery treatments, gastrointestinal function is impaired among patients with CRC. Acupressure is a promising technique that utilises force to stimulate acupoints for improving gastrointestinal function.AimsThis study mainly aims to evaluate the effectiveness of acupressure and determine its potential clinical application to improve postoperative gastrointestinal function among patients undergoing CRC surgeries.MethodsThis study comprised three phases. Phase I was a systematic review to examine the effects of acupressure on the postoperative gastrointestinal function of patients undergoing abdominal surgeries from literature. The results of the systematic review were used to guide the development of an evidence-based protocol. Phase II was a small-scale pilot study that involved a randomised controlled trial (RCT, n=13) and a qualitative study (n=4) to assess the feasibility and acceptability of the protocol for a full-scale study. Phase III was the main study that adopted a RCT (n=112) and qualitative interviews of patients (n=12) and nurses (n=11). Adult patients (≥ 18 years old) who were scheduled to undergo CRC surgeries were recruited and randomised to receive acupressure or sham acupressure at the acupoint Stomach 36 (ST36, 足三裡) for five days after the operation. Primary outcomes included time of first passage of flatus and defecation and secondary outcomes included postoperative nausea and vomiting, bowel motility, abdominal distension and pain. The first passage of flatus and defecation were analysed using student t-test and regression analysis. Generalised estimating equation (GEE) models were used to compare the effects of acupressure on gastrointestinal symptoms at different time points.ResultsIn Phase I, the systematic review included nine studies and 1,191 participants. The meta-analysis results showed that acupressure significantly reduced the incidence of postoperative nausea (odds ratio, OR 0.56, 95% confidence interval, CI 0.44-0.72, P<0.01) and vomiting (OR 0.57, 95% CI 0.37-0.88, P=0.01) compared with the control. No severe side effects of acupressure were reported.In Phase II, the pilot study demonstrated the feasibility of the protocol in clinical setting and recommended the adoption of 10-dose acupressure in the main study. Additionally, the recruitment process of the patients was better than expected, with a refusal rate of 7.1% only. Acupressure was well accepted by the participants, as reflected from the qualitative data.In Phase III, the result of the multivariate regression analysis showed that acupressure significantly shortened the time interval of first flatus passage of the patients by 11.08 hours (95% CI -19.36 to -2.81) (P<0.01) with the effect size at 0.27. No significant influences of acupressure on the first passage of defecation were found. Furthermore, the GEE models showed that patients who received acupressure exhibited significantly improved bowel motility (effect size 0.21) and decreased abdominal distension (effect size -0.18) compared with the control. Additionally, the qualitative results provided supplementary information with five themes were generated, including acceptability, perceived effects of acupressure, suggestions for acupressure intervention, facilitators of clinical application, and barriers of clinical application. Generally, acupressure was well-accepted by patients and nurses, and no side effects were detected during the study. The procedure generally satisfied the patients, and some suggestions, including prolonging the duration of acupressure and adjusting force, were proposed. In the future, acupressure is expected to be applied in clinical settings considering several factors (i.e. support from management and doctors; knowledge and training; human resources; charge and implementer).ConclusionThis study demonstrated the feasibility and effectiveness of acupressure in clinical settings. Acupressure effectively shortened the time interval of the first flatus passage, improved bowel motility and reduced abdominal distension. Furthermore, acupressure was well-accepted by patients and nurses. Overall, the findings provide additional knowledge and evidence for the clinical implementation of acupressure to improve postoperative gastrointestinal function among patients undergoing CRC surgery.研究背景結直腸癌（colorectal cancer, CRC）是2018 年全球第三大常見癌症。手術治療後，結直腸癌患者常出現胃腸功能障礙。穴位按壓是一種利用力來刺激穴位的技術，它可以用來改善胃腸功能。研究目的本研究旨在評估穴位按壓對改善結直腸癌患者術後胃腸功能的有效性，並探究其在改善結直腸癌手術患者術後胃腸功能方面的潛在臨床應用。研究方法該研究包括三個階段。第一階段是一項系統評價，旨在確定以往文獻中穴位按壓對接受腹部手術患者術後胃腸功能的影響。第一階段的結果用於指導基於證據的研究計畫的開發。第二階段是一項小規模預試驗研究，採用隨機對照試驗（n = 13）和質性研究（n = 4）方法，以評估該方案在正式研究中的可行性和可接受性。第三階段是主要研究，採用隨機對照試驗（n = 112）和質性研究，其中包括患者（n = 12）和護士（n = 11）的質性訪談。招募計劃接受結直腸癌手術的成年患者（≥18 歲）並被隨機分配到接受足三裡穴位按壓組或安慰組，持續5 天。主要結果包括第一次排氣和排便的時間，次要結果包括術後噁心程度，嘔吐次數，腸鳴音次數，腹脹和疼痛的程度。使用獨立樣本t 檢驗和回歸分析比較兩組間在第一次排氣和排便時間的差異。廣義估計方程模型用於比較穴位按壓在不同時間點對胃腸道症狀的影響。研究結果在第一階段，系統評價共納入9 項研究和1,191 名參與者。薈萃分析結果顯示，穴位按壓顯著降低了術後噁心的發生 (odds ratio, OR 0.56,95% confidence interval, CI 0.44-0.72, P＜0.01) 和嘔吐的發生率 (OR 0.57,95% CI 0.37-0.88, P=0.01) 。文獻沒有報告穴位按壓的嚴重副作用。在第二階段，預試驗研究證明瞭該方案在臨床環境中的可行性，並建議在主要研究中採用10 次（一天兩次）的穴位按壓。此外，患者的招募過程比預期好，拒絕率僅為7.1%。定性數據表明，參與者很接受穴位按壓。在第三階段，多元回歸分析的結果顯示，穴位按壓顯著縮短了患者首次排氣時間11.08 小时 (95% CI -19.36 to -2.81) (P<0.01) ，效應大小為0.27。沒有發現穴位按壓對術後第一次排便時間的顯著影響。此外，GEE 模型顯示，與對照組相比，接受穴位按壓的患者表現出顯著增加的腸鳴音（效應大小0.21）和腹脹程度降低（效應大小-0.18）。此外，質性研究提供了五個主題的補充資訊，包括可接受性，穴位按壓法的感知效果，穴位按壓法幹預的建議，臨床應用的促進因素和臨床應用的障礙。一般來說，穴位按壓被患者和護士廣泛接受，並且在研究期間沒有發現副作用。穴位按壓過程總體上滿足了患者，提出的建議包括延長穴位按壓的持續時間等。在未來，考慮到多個因素的影響（如：管理人員和醫生的支援；知識和培訓；人力資源；收費和實施者），預計穴位按壓可以應用於臨床環境。研究結論該研究證明穴位按壓對改善結直腸癌手術患者部分胃腸功能的有效性。穴位按壓有效縮短了結直腸癌術後患者第一次排氣的時間，改善了腸蠕動並減少了腹脹。此外，穴位按壓被患者和護士廣泛接受，在克服不利因素（如：知識和培訓；人力資源；收費和實施者）之後，具有應用於臨床環境的潛在價值。總之，本研究為穴位按壓對改善結直腸癌手術患者的術後胃腸功能提供了知識和證據，對進一步的研究具有指導意義，並且對臨床實踐具有啟示的作用。Liu, Yunhong.Parallel title from appendix 10.Thesis Ph.D. Chinese University of Hong Kong 2019.Includes bibliographical references (leaves 291-372).Abstracts also in Chinese; some appendixes also in Chinese.Title from PDF title page (viewed on 27, November, 2020).Liu, Yunhong
Data anomaly detection for structural health monitoring by multi-view representation based on local binary patterns
No full textFunding Information: The authors greatly appreciate the financial support from the Academy of Finland (Decision number: 339493). The authors also appreciate the kind support from Prof. Hui Li from Lab of Intelligent Civil Infrastructure (LiCi) for sharing the dataset and Prof. Yuequan Bao for the valuable comments. We also acknowledge the computational resources provided by the Aalto Science-IT project. Publisher Copyright: © 2022 The Author(s)Structural health monitoring (SHM) systems provide opportunities to understand the structural behaviors remotely in real-time. However, anomalous measurement data are frequently collected from structures, which greatly affect the results of further analyses. Hence, detecting anomalous data is crucial for SHM systems. In this article, we present a simple yet efficient approach that incorporates complementary information obtained from multi-view local binary patterns (LBP) and random forests (RF) to distinguish data anomalies. Acceleration data are first converted into gray-scale image data. The LBP texture features are extracted in three different views from the converted images, which are further aggregated as the anomaly representation for the final RF prediction. Consequently, multiple types of data anomalies can be accurately identified. Extensive experiments validated on an acceleration dataset acquired on a long-span cable-stayed bridge highlight the advantages of the proposed method. State-of-the-art performances are achieved by the proposed method, demonstrating its effectiveness and generalization ability.Peer reviewe
Bibliometric analysis of papers on mild cognitive impairment nursing in China
No full textPurpose: To supply further references by analyzing the status of research on mild cognitive impairment nursing in China. Methods: Papers on mild cognitive impairment nursing published between 2005 and 2014 were collected from China National Knowledge Infrastructure, Wanfang Data, and China Biological Medicine database, while their publication dates, journals, and types were subjected to a bibliometric analysis using NoteExpress and Excel. Results: A total of 68 papers were collected from the selected databases. The number of papers on mild cognitive impairment nursing increased annually. The selected papers were published in 44 journals, 55.88% of them were published in core journals, 35.29% received funding support, 35.29% were published by hospitals affiliated to colleges, 47.06% were published by other local hospitals, author collaboration is 2.66, and 66.18% showed co-authorship. These papers covered a wide range of topics, but were only conducted based on clinical interventions. Around 29.41% of these papers had a citation frequency of over 5, the highest citation frequency was 29, and the highest h-index was 23. Conclusion: Beijing and Shanghai established core author groups for mild cognitive impairment nursing research. These studies should focus on the community and psychological nursing of such impairment. Targeted nursing interventions on different types of mild cognitive impairment should be adopted, new avenues for research should be opened, and various research methods should be introduced.

An analysis of the Concept of Freedom and its Implications for Educational Theory and Practice in Egypt, 1805-2000
No full textThe current study attempts to analyse the learners' right to freedom in education in order to determine the nature and content of their education. This analysis will be in relation to the philosophy of education in Egypt to improve the efficiency of the educational system. In this sense the aims of the study can be determined as follows: first to propose a theoretical framework of freedom in education in relation to its meaning, conditions, restrictions and
value, secondly, to develop this theoretical framework of education based on freedom so that it suits Egyptian society, can improve the efficiency of the educational system through the idea of freedom, and thirdly, to identify the difficulties and challenges that might
confront the claim to freedom in education in Egypt.
To achieve these aims the study contains seven chapters, an introduction, a conclusion and appendix that are necessary to achieve its aims and answer its questions. The introduction discusses the general outline of the study and the major issues, questions, aims, methodology and plan of the study. The main aim of chapter one is to analyse the concept of freedom in western and Islamic thought to build a theoretical framework of the meaning of freedom, its conditions and value, which is necessary and important to construct a theoretical framework of the meaning, conditions and value of freedom in education for
learners at school level. Chapter two aims to construct a theoretical framework of freedom in education that will depend on the analysis of the concept of freedom made in chapter one. This analysis will deal with the implications of freedom in education with respect to its conditions, restrictions and value in education. Through this analysis, chapter two aims also to analyse and examine the learners' rights to be free regarding their education. To have a
complete theoretical framework of freedom in education, chapter three discusses other implications with respect to restrictions which might limit learners' freedom by being
subject to state authority.
Chapter four investigates and analyses freedom in educational theory and practice in the history of Egypt from 1805 to 1991, whereas chapter five focuses on the period from 1992 to 2000. Following the analysis of the concept of freedom and its implications in education that will be made in the first five chapters, it would be sensible to construct a framework of educational theory based on freedom that, on one hand, should suite the Egyptian context in chapter six, on the other hand, that guarantees a range of freedom that allows learners and
society derive benefit from its value in education. Having proposed a framework of a theory of education based on freedom that suits the Egyptian context to improve the
efficiency of its educational system chapter seven will discover and examine the conditions and difficulties which need to be considered for the successful implementation of freedom in education. Also, the study will attempt to give some suggestions that might help to reduce the gap between the educational situation, its circumstances and the conditions that must be satisfied for the successful implementation of freedom in education
