| 2 | 基于支持向量机的图像语义分类(英文)显示文摘图像的低层可视特征与高层语义特征之间存在着一道鸿沟,人们不能直接理解由计算机自动生成的低层特征.另外,基于内容的图像分类和检索的性能极大地依赖于可视特征的提取和描述.出于这些考虑,提出了新的图像纹理、边缘描述子提取方法,并将它们表示为直方图.在此基础上,集成纹理、边缘和颜色直方图作为图像的特征向量,用支持向量机(SVM)实现图像的语义分类.实验结果表明,集成的图像特征表示在图像分类实验中取得了很好的效果,具有比其他特征表示(如Gabor纹理、颜色直方图)更好的性能. | 万华林 Morshed U.Chowdhury | 2003 | 软件学报2003，14，11： | 33 |
| 3 | Rubber band ligation for 750 cases of symptomatic hemorrhoids out of 2200 cases显示文摘AIM: To study the results for the treatment of symptomatic hemorrhoids using rubber band ligation (RBL) method. METHODS: A retrospective study for 750 patients who came to the colorectal unit from June, 1998 to September, 2006, data was retrieved from archived fi les. RBL was performed using the Mc Gown applicator on an outpatient basis. The patients were asked to return to out-patient clinic for follow up at 2 wk, 1 mo, 6 mo and through telephone call every 6 mo for 2 years). RESULTS: After RBL, 696 patients (92.8%) were cured with no difference in outcome for second or third degree hemorrhoids (P = 0.31). Symptomatic recurrence was detected in 11.04% after 2 years. A total of 52 patients (6.93%) had 77 complications from RBL which required no hospitalization. Complications were pain, rectal bleeding and vaso-vagal symptoms(4.13%, 4.13% and 1.33% of patients, respectively). At 1 mo there were a significant improvement in mean SF-36 scores over baseline in five items, while after 2 years there were improvement in all items over baseline, but not significant. No significant manometeric changes after band ligation. CONCLUSION: RBL is a simple, safe and effective method for treating symptomatic second and third degree hemorrhoids as an out patient procedure with signifi cant improvement in quality of life. RBL doesn't alter ano-rectal functions. | Ayman M El Nakeeb Amir A Fikry Waleed H Omar Elyamani M Fouda Tito A El Metwally Hosam E Ghazy Sabry A Badr Mohmed Y Abu Elkhar Salih M Elawady Hisham H Abd Elmoniam Waiel W Khafagy Mosaad M Morshed Ramadan E El Lithy Mohamed E Farid | 2008 | World Journal of Gastroenterology2008，14，42： | 24 |
| 4 | Comparative assessment of total polyphenols, antioxidant and antimicrobial activity of different tea varieties of Bangladesh显示文摘Objective: To determine the total polyphenol content, antioxidant activity and antibacterial properties of the extracts of different Bangladeshi tea varieties such as flowery broken orange pekoe, broken orange pekoe, red dust and green tea.Methods: Total phenolic and flavonoid contents were determined by Folin–Ciocalteu and aluminum chloride colorimetric assay, respectively.The antioxidant capacity was determined by ferric ion reducing antioxidant power and phosphomolybdenum method.Antibacterial activity was evaluated by disc diffusion method in agar plate and subsequently, the minimum inhibitory concentration was determined by broth dilution method.Results: Total phenolic and flavonoid contents were significantly higher(P < 0.05) in green tea compared to other three black tea varieties.The green tea also showed a higher free radical scavenging and antioxidant activities than all the other tea varieties tested(P < 0.05).In addition, the extracts of all four tea varieties showed inhibitory activity against several pathogenic bacteria and also the same trend of higher antimicrobial activity of green tea than other tea varieties was observed.Conclusions: Taken together, the results of this study demonstrated that Bangladeshi tea,especially the green tea, may act as a substitute for natural antioxidants and as a promising antibacterial agent for beneficial influence in human health. | Yead Morshed Nibir Ahmed Faisal Sumit Anwarul Azim Akhand Nazmul Ahsan Mohammad Shahnoor Hossain | 2017 | Asian Pacific Journal of Tropical Biomedicine2017，7，4： | 6 |
| 5 | Big Data Analytics in Telecommunications: Literature Review and Architecture Recommendations显示文摘This paper focuses on facilitating state-of-the-art applications of big data analytics(BDA) architectures and infrastructures to telecommunications(telecom) industrial sector.Telecom companies are dealing with terabytes to petabytes of data on a daily basis. Io T applications in telecom are further contributing to this data deluge. Recent advances in BDA have exposed new opportunities to get actionable insights from telecom big data. These benefits and the fast-changing BDA technology landscape make it important to investigate existing BDA applications to telecom sector. For this, we initially determine published research on BDA applications to telecom through a systematic literature review through which we filter 38 articles and categorize them in frameworks, use cases, literature reviews, white papers and experimental validations. We also discuss the benefits and challenges mentioned in these articles. We find that experiments are all proof of concepts(POC) on a severely limited BDA technology stack(as compared to the available technology stack), i.e.,we did not find any work focusing on full-fledged BDA implementation in an operational telecom environment. To facilitate these applications at research-level, we propose a state-of-the-art lambda architecture for BDA pipeline implementation(called Lambda Tel) based completely on open source BDA technologies and the standard Python language, along with relevant guidelines.We discovered only one research paper which presented a relatively-limited lambda architecture using the proprietary AWS cloud infrastructure. We believe Lambda Tel presents a clear roadmap for telecom industry practitioners to implement and enhance BDA applications in their enterprises. | Hira Zahid Tariq Mahmood Ahsan Morshed Timos Sellis | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，1： | 6 |
| 6 | A Nonlinear Coordinated Approach to Enhance the Transient Stability of Wind Energy-Based Power Systems显示文摘This paper proposes a novel framework that enables the simultaneous coordination of the controllers of doubly fed induction generators(DFIGs) and synchronous generators(SGs).The proposed coordination approach is based on the zero dynamics method aims at enhancing the transient stability of multi-machine power systems under a wide range of operating conditions. The proposed approach was implemented to the IEEE39-bus power systems. Transient stability margin measured in terms of critical clearing time along with eigenvalue analysis and time domain simulations were considered in the performance assessment. The obtained results were also compared to those achieved using a conventional power system stabilizer/power oscillation(PSS/POD) technique and the interconnection and damping assignment passivity-based controller(IDA-PBC). The performance analysis confirmed the ability of the proposed approach to enhance damping and improve system’s transient stability margin under a wide range of operating conditions. | Mohammad Javad Morshed | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，4： | 4 |

| 8 | Energy-efficient virtual machine consolidation algorithm in cloud data centers显示文摘Cloud data centers consume a multitude of power leading to the problem of high energy consumption. In order to solve this problem, an energy-efficient virtual machine(VM) consolidation algorithm named PVDE(prediction-based VM deployment algorithm for energy efficiency) is presented. The proposed algorithm uses linear weighted method to predict the load of a host and classifies the hosts in the data center, based on the predicted host load, into four classes for the purpose of VMs migration. We also propose four types of VM selection algorithms for the purpose of determining potential VMs to be migrated. We performed extensive performance analysis of the proposed algorithms. Experimental results show that, in contrast to other energy-saving algorithms, the algorithm proposed in this work significantly reduces the energy consumption and maintains low service level agreement(SLA) violations. | 周舟 胡志刚 于俊洋 Jemal Abawajy Morshed Chowdhury | 2017 | Journal of Central South University2017，24，10： | 2 |
| 9 | Big Data Analytics in Healthcare——A Systematic Literature Review and Roadmap for Practical Implementation显示文摘The advent of healthcare information management systems(HIMSs)continues to produce large volumes of healthcare data for patient care and compliance and regulatory requirements at a global scale.Analysis of this big data allows for boundless potential outcomes for discovering knowledge.Big data analytics(BDA)in healthcare can,for instance,help determine causes of diseases,generate effective diagnoses,enhance Qo S guarantees by increasing efficiency of the healthcare delivery and effectiveness and viability of treatments,generate accurate predictions of readmissions,enhance clinical care,and pinpoint opportunities for cost savings.However,BDA implementations in any domain are generally complicated and resource-intensive with a high failure rate and no roadmap or success strategies to guide the practitioners.In this paper,we present a comprehensive roadmap to derive insights from BDA in the healthcare(patient care)domain,based on the results of a systematic literature review.We initially determine big data characteristics for healthcare and then review BDA applications to healthcare in academic research focusing particularly on No SQL databases.We also identify the limitations and challenges of these applications and justify the potential of No SQL databases to address these challenges and further enhance BDA healthcare research.We then propose and describe a state-of-the-art BDA architecture called Med-BDA for healthcare domain which solves all current BDA challenges and is based on the latest zeta big data paradigm.We also present success strategies to ensure the working of Med-BDA along with outlining the major benefits of BDA applications to healthcare.Finally,we compare our work with other related literature reviews across twelve hallmark features to justify the novelty and importance of our work.The aforementioned contributions of our work are collectively unique and clearly present a roadmap for clinical administrators,practitioners and professionals to successfully implement BDA initiatives in their organizations. | Sohail Imran Tariq Mahmood Ahsan Morshed Timos Sellis | 2021 | IEEE/CAA Journal of Automatica Sinica2021，8，1： | 2 |
| 10 | Cooling performance of earth-to-air heat exchangers applied to a poultry barn in semi-desert areas of south Iraq显示文摘Earth-to-air heat exchangers(EAHE)can reduce the energy consumption required for heating and cooling of buildings.The composition and the thermal characteristics of the soil influence the heat exchange capacity,and the soil moisture can furthermore affect thermal performance of EAHE.The aim of this study was to compare the thermal performance of EAHE in dry and artificially wetted soil.Tests were carried out in the Basra Province(Iraq),in a semi-desert area.Two experimental EAHE were built in a poultry barn and tested from June 2013 to September 2013.The pipe exchangers were buried at 2 m deep.One heat exchanger operated in dry soil(DE),while the other one operated in artificially wetted soil(WE).In the WE system,a drip tubing placed 10 cm above the air pipe wetted the soil around the exchanger.Air temperatures at the inlet and at the outlet of both the exchangers as well as soil temperature at 2 m deep were continuously monitored.The experimental results confirmed that wetting the soil around EAHE improves the general heat exchange efficiency.The coefficient of cooling performance(COP)of the earth-to-air heat exchangers system was evaluated on the basis of the ratio between the heat removed from the air or added to the air and the energy input.During the day,with an average COP of 6.41,the WE system cooled the air more than the DE system,which reported a value of 5.07.On average,in the hottest hours of the day,the outlet temperature of the WE was 37.35℃ while in the DE it was 38.91℃.Moreover,during the nighttime,the WE system warmed the air more than the DE system. | Wasseem Morshed Lorenzo Leso Leonardo Conti Giuseppe Rossi Stefano Simonini Matteo Barbari | 2018 | International Journal of Agricultural and Biological Engineering2018，11，3： | 2 |
| 11 | A Sliding Mode Approach to Enhance the Power Quality of Wind Turbines Under Unbalanced Voltage Conditions显示文摘An integral terminal sliding mode-based control design is proposed in this paper to enhance the power quality of wind turbines under unbalanced voltage conditions. The design combines the robustness, fast response, and high quality transient characteristics of the integral terminal sliding mode control with the estimation properties of disturbance observers. The controller gains were auto-tuned using a fuzzy logic approach.The effectiveness of the proposed design was assessed under deep voltage sag conditions and parameter variations. Its dynamic response was also compared to that of a standard SMC approach.The performance analysis and simulation results confirmed the ability of the proposed approach to maintain the active power,currents, DC-link voltage and electromagnetic torque within their acceptable ranges even under the most severe unbalanced voltage conditions. It was also shown to be robust to uncertainties and parameter variations, while effectively mitigating chattering in comparison with the standard SMC. | Mohammad Javad Morshed Afef Fekih | 2019 | IEEE/CAA Journal of Automatica Sinica2019，6，2： | 2 |
