| 1 | A Survey on Fault Diagnosis and Fault Tolerant Methodologies for Permanent Magnet Synchronous Machines显示文摘This paper presents a comprehensive survey of fault diagnosis and fault tolerant approaches for permanent magnet synchronous machines(PMSM).PMSMs are prominent in the pervading usage of electric motors,for their high efficiency,great robustness,reliability and low torque inertia.In spite of their extensive appliance,they can be quite non-resilient and inadequate in operation when faults appear in motor drive apparatus such as inverters,stator windings,sensors,etc.These may lead to insulation failure,torque fluctuations,overcurrent or even system collapse.On that account,fault diagnosis and fault tolerant methods are equipped to enhance the stability and robustness in PMSMs.Progressive methodologies of PMSM fault diagnosis and tolerance are classified,discussed,reviewed and compared in this paper,beginning with mat hematical modeling of PMSM and then scrutinizing various fault conditions in PMSMs.Finally,the scope of research on the topic is highlighted.The contribution of this review is to emphasize optimistic schemes and to assist researchers with the latest trends in this field for future directions. | Erphan A.Bhuiyan Md.Maeenul Azad Akhand Sajal K.Das Md.F.Ali Z.Tasneem Md.R.Islam D.K.Saha Faisal R.Badal Md.H.Ahamed S.I.Moyeen | 2020 | International Journal of Automation and computing2020，17，6： | 5 |
| 2 | Efficacy of selective laser trabeculoplasty following incisional glaucoma surgery显示文摘AIM: To evaluate the efficacy of selective laser trabeculoplasty(SLT) in glaucomatous eyes with previous incisional glaucoma surgery. METHODS: A retrospective cohort of eyes that underwent SLT at a single institution from 2013-2015 were followed for 1 y. Reduction in intraocular pressure(IOP) following SLT was evaluated in eyes with prior trabeculectomy with Ex Press mini shunt(Alcon, Ft Worth, TX, USA), Ahmed valve(New World Medical, Cucamonga, CA, USA), or combined phacoemulsification-trabeculectomy. A control group was included with eyes without prior surgery that underwent SLT. Success was defined as >20% drop in IOP from pre-SLT baseline. RESULTS: One-hundred and six eyes were included with 53 in both the prior glaucoma surgery(PGS) and no prior glaucoma surgery(NPGS) groups. Mean pre-SLT IOP was 19.2±4.3 and 20.6±6.0 mm Hg for PGS and NPGS groups, respectively(P=0.17). Both groups produced statistically significant IOP reductions at 1 and 6 mo(P<0.04). At 6 mo, mean IOP reduction reached 7.3% and 10.8% for the PGS and NPGS groups, respectively(P=0.42). Overall, 27.9% and 31.7% of eyes in PGS and NPGS groups met success criteria at 1 y(P=0.70). In the PGS group, eyes with baseline IOP ≥21 mm Hg had IOP reductions of 18.1%(P<0.001), 16.7%(P<0.01), and 8.4%(P=0.31) compared to eyes with baseline IOP <21 mm Hg who had IOP reductions of 2.3%(P=0.39), 3.4%(P=0.19), and 1.1%(P=0.72) at 1, 6 mo, and 1 y, respectively. CONCLUSION: SLT is efficacious in eyes with prior incisional glaucoma surgery and results in similar IOP reductions compared to eyes without PGS. A larger IOP reduction is observed following SLT in eyes with higher pre-SLT IOP. | Robert Allan Sharpe Leah L Kammerdiener David B.Williams Sudeep K.Das Matthew J.Nutaitis | 2018 | International Journal of Ophthalmology(English edition)2018，11，1： | 3 |
| 3 | An improved robust stability analysis for systems with two delays by extracting overlapping feature显示文摘In this paper,a delay-dependent robust stability criterion is proposed for linear systems with two delays.For delay-dependent stable systems,the delays are very small in nature.So,they may overlap each other.This overlapping information may be exploited to obtain a less conservative criterion.To extract such information,a special type of simple Lyapunov–Krasovskii functional is considered.To derive the criterion in form of Linear Matrix inequalities,a matrix variable approach is used.Some numerical examples are presented to validate the less conservativeness of the proposed criterion. | Dushmanta K.Das Sandip Ghosh Bidyadhar Subudhi | 2015 | Journal of Control and Decision2015，2，2： | 3 |
| 4 | Actinobacteria-enhanced plant growth, nutrient acquisition, and crop protection:Advances in soil, plant, and microbial multifactorial interactions显示文摘Agricultural areas of land are deteriorating every day owing to population increase, rapid urbanization, and industrialization. To feed today’s huge populations, increased crop production is required from smaller areas, which warrants the continuous application of high doses of inorganic fertilizers to agricultural land. These cause damage to soil health and, therefore, nutrient imbalance conditions in arable soils. Under these conditions, the benefits of microbial inoculants (such as Actinobacteria) as replacements for harmful chemicals and promoting ecofriendly sustainable farming practices have been made clear through recent technological advances. There are multifunctional traits involved in the production of different types of bioactive compounds responsible for plant growth promotion, and the biocontrol of phytopathogens has reduced the use of chemical fertilizers and pesticides. There are some well-known groups of nitrogen-fixing Actinobacteria, such as Frankia, which undergo mutualism with plants and offer enhanced symbiotic trade-offs.In addition to nitrogen fixation, increasing availability of major plant nutrients in soil due to the solubilization of immobilized forms of phosphorus and potassium compounds, production of phytohormones, such as indole-3-acetic acid, indole-3-pyruvic acid, gibberellins, and cytokinins, improving organic matter decomposition by releasing cellulases, xylanase, glucanases, lipases, and proteases, and suppression of soil-borne pathogens by the production of siderophores, ammonia, hydrogen cyanide, and chitinase are important features of Actinobacteria useful for combating biotic and abiotic stresses in plants.The positive influence of Actinobacteria on soil fertility and plant health has motivated us to compile this review of important findings associated with sustaining plant productivity in the long run. | Debasis MITRA Rittick MONDAL Bahman KHOSHRU Ansuman SENAPATI T.K.RADHA Bhaswatimayee MAHAKUR Navendra UNIYAL Ei Mon MYO Hanane BOUTAJ Beatriz Elena GUERRA SIERRA Periyasamy PANNEERSELVAM Arakalagud Nanjundaiah GANESHAMURTHY Snežana ANÐELKOVIĆ Tanja VASIĆ Anju RANI Subhadeep DUTTA Pradeep K.DAS MOHAPATRA | 2022 | Pedosphere2022，32，1： | 3 |
| 5 | A survey on control issues in renewable energy integration and microgrid显示文摘This paper describes the usefulness of renewable energy throughout the world to generate power. Renewable energy adds a remarkable scope in power system. Renewable energy sources act as the prime mover of a microgrid. The Microgrid is a small network of power system with distributed generation (DG) units connected in parallel. The integration challenges of renewable energy sources and the control of microgrid are described in this paper. The varied nature of DG system produces voltage and frequency deviation. The unknown nature of the load produces un-modeled dynamics. This un-modeled dynamic introduces measurable effects on the performance of the microgrid. This paper investigates the performance of the microgrid against different scenarios. The voltage of the microgrid is controlled by using different controllers and their results are also investigated. The performance of controllers is investigated using MATLAB/Simulink SimPowerSystems. | Faisal R.Badal Purnima Das Subrata K.Sarker Sajal K.Das | 2019 | Protection and Control of Modern Power Systems2019，4，1： | 2 |

| 18 | Rice(Oryza sativa L.)plant protection using dual biological control and plant growth-promoting agents:Current scenarios and future prospects显示文摘Various microorganisms live in association with different parts of plants and can be harmful,neutral,or beneficial to plant health.Some microbial inhabitants of plants can control plant diseases by contesting with,predating on,or antagonizing plant pathogens and by inducing systems for plant defense.A range of methods,including plant growth-promoting microorganisms(PGPMs)as biological control agents(BCAs)(BCA-PGPMs)are used for the biological management and control of plant pathogens.Some BCAs interact with plants by inducing resistance or priming plants without direct interaction with the pathogen.Other BCAs operate via nutrient competition or other mechanisms to modulate the growth conditions for the pathogen.Generally,PGPMs can be applied alone or together with other chemicals or carriers to control various crop diseases.This review highlights the effective types of BCA-PGPMs and their applications,roles,carrier based-formulations,and responses to rice(Oryza sativa L.)pathogens.Future plant disease management prospects are promising,and growers’increasing demand for BCA-PGPM products can be exploited as an effective approach to the management of plant diseases,as well as to improve yield,environmental protection,biological resources,and agricultural system sustainability. | Debasis MITRA Sergio DE LOS SANTOS-VILLALOBOS Fannie Isela PARRA-COTA Ana María Garcia MONTELONGO Erika Lorena BLANCO Vanessa L.LIRA Adeyemi N.OLATUNBOSUN Bahman KHOSHRU Rittick MONDAL Parameswaran CHIDAMBARANATHAN Periyasamy PANNEERSELVAM Pradeep K.DAS MOHAPATRA | 2023 | Pedosphere2023，33，2： | 0 |
| 19 | Oscillatory Shannon entropy in the process of equilibration of nonequilibrium crystalline systems显示文摘We present a study of the equilibration process of some nonequilibrium crystalline systems by means of molecular dynamics simulation technique. The nonequilibrium conditions are achieved in the systems by randomly defining velocity components of the constituent atoms. The calculated Shannon entropy from the probability distribution of the kinetic energy among the atoms at different instants during the process of equilibration shows oscillation as the system relaxes towards equilibrium. Fourier transformations of these oscillating Shannon entropies reveal the existence of Debye frequency of the concerned system. | A.Giri Nilangshu K.Das P.Barat | 2015 | Chinese Physics B2015，24，8： | 0 |
| 20 | 与结核病有关的胸部X线异常阴影:判断活动性病例的重复性和发生数显示文摘背景:呼吸系统疾病三级医疗保健中心。 目的:胸部X线检查是结核病(TB)筛查和诊断的一个主要工具。我们对申请到加拿大的移民的活动性结核病筛查的X线胸片分类系统的重复性进行评价。我们同样对这个分类系统关于筛查的移民、结核菌素阳性的密切接触者及具有相应症状的病人中活动性病例发现的可靠性进行评价。 方法:以随机抽取筛查胸片中10%的样本进行复读来评价其重复性。可靠性由经过详细临床评价的病人的最终临床和细菌学诊断来评定。 结果:阅读者之间用五种粗略分类的一致性是中等的(0.44-0.56 Kappa),而阅读者内的一致性更真实(0.59-0.72 Kappa)。经过年龄和病人组调整后,活动性结核病的调整比值比与正常或微小发现或肉芽肿、纤维化改变的比为10.2(95%可信区间[CI]3.2-33);团块或者胸膜腔渗液为11.6(95%CI3.6-37);实质性浸润的为46.1(95%CI 18-117)。结核菌素阳性的密切接触者中,如果X线胸片显示出团块、胸膜病变或者实质性浸润的,成为活动性结核病的几率大于50%。 结论:与结核病有关的X线胸片异常的五种粗略类型的简单分类,阅读具有中等到很好的重复性,有一定的可靠性。 | S.Graham K.Das Gupta R.J.Hidvegi R.Hanson J.Kosiuk K.Al Zahrani D.Menzies 王海东 | 2002 | 国际结核病与肺部疾病杂志2002，，2： | 0 |
