| 1 | 热循环对锅炉管热喷涂Ni-Cr基纳米涂层的影响(英文)显示文摘采用机械球磨法制备Ni-Cr基纳米原料粉末。粉末颗粒在行星球磨机中反复经历焊合、碎裂和重焊合过程。采用超音速火焰喷涂工艺(HVOF)在碳钢管上喷涂球磨纳米粉末。利用金相显微镜、XRD、扫描电子显微镜(SEM),高分辨透射电子显微镜(HR-TEM)、能谱(EDS)和显微硬度测试对原料粉和HVOF喷涂涂层进行表征。对喷涂和未喷涂试样进行热循环分析,研究相、冶金性能和显微硬度的变化。与传统喷涂试样相比,Ni-Cr纳米涂层试样具有更高的力学和冶金性能。与传统涂层相比,纳米涂层的显微组织更均匀和紧密。 | V.SENTHILKUMAR B.THIYAGARAJAN M.DURAISELVAM K.KARTHICK | 2015 | Transactions of Nonferrous Metals Society of China2015，25，5： | 2 |
| 2 | Comprehensive Study,Design and Economic Feasibility Analysis of Solar PV Powered Water Pumping System显示文摘The energy efficient product can be operated with longer duration.They offer wonderful solutions compared to other conventional water pumping system as it needs less maintenance,simple in installation,zero fuel cost,longer operating life,highly reliable and free from production of greenhouse gases.In this paper we analyzed the different topologies of DC–DC converter in terms of their operating region of MPPT,quality of input and output currents.We discussed the MPPT algorithms to address partial shading effects in SPV array,present state of the technology,factors affecting the performance of the system,efficiency improvements and identified the research gaps.Also,the economic feasibility analysis has been done for the real time scenario using the Homer Pro software.The estimation of total dynamic head and horse power calculation has been done to decide the total load capacity.The economic analysis results such as cumulative cash flow over project lifetime of 25 years are presented.It is observed that the capital investment requirement is$7,425 for installing Fronius PV system that has a nominal capacity of 2.47 kW and annualized savings will be$134.93.In the long-term perspective,the return on investment is−2.18%as per the present tariff plan. | K.Karthick K.Jaiganesh S.Kavaskar | 2021 | Energy Engineering2021，118，6： | 0 |
| 3 | Iterative Dichotomiser Posteriori Method Based Service Attack Detection in Cloud Computing显示文摘Cloud computing(CC)is an advanced technology that provides access to predictive resources and data sharing.The cloud environment represents the right type regarding cloud usage model ownership,size,and rights to access.It introduces the scope and nature of cloud computing.In recent times,all processes are fed into the system for which consumer data and cache size are required.One of the most security issues in the cloud environment is Distributed Denial of Ser-vice(DDoS)attacks,responsible for cloud server overloading.This proposed sys-tem ID3(Iterative Dichotomiser 3)Maximum Multifactor Dimensionality Posteriori Method(ID3-MMDP)is used to overcome the drawback and a rela-tively simple way to execute and for the detection of(DDoS)attack.First,the pro-posed ID3-MMDP method calls for the resources of the cloud platform and then implements the attack detection technology based on information entropy to detect DDoS attacks.Since because the entropy value can show the discrete or aggregated characteristics of the current data set,it can be used for the detection of abnormal dataflow,User-uploaded data,ID3-MMDP system checks and read risk measurement and processing,bug ratingfile size changes,orfile name changes and changes in the format design of the data size entropy value.Unique properties can be used whenever the program approaches any data error to detect abnormal data services.Finally,the experiment also verifies the DDoS attack detection capability algorithm. | B.Dhiyanesh K.Karthick R.Radha Anita Venaik | 2023 | Computer Systems Science & Engineering2023，44，2： | 0 |
