| 1 | Cyber Attack Protection and Control of Microgrids显示文摘Recently, the smart grid has been considered as a next-generation power system to modernize the traditional grid to improve its security, connectivity, efficiency and sustainability.Unfortunately, the smart grid is susceptible to malicious cyber attacks, which can create serious technical, economical, social and control problems in power network operations. In contrast to the traditional cyber attack minimization techniques, this paper proposes a recursive systematic convolutional(RSC) code and Kalman filter(KF) based method in the context of smart grids.Specifically, the proposed RSC code is used to add redundancy in the microgrid states, and the log maximum a-posterior is used to recover the state information, which is affected by random noises and cyber attacks. Once the estimated states are obtained by KF algorithm, a semidefinite programming based optimal feedback controller is proposed to regulate the system states, so that the power system can operate properly. Test results show that the proposed approach can accurately mitigate the cyber attacks and properly estimate and control the system states. | Md Masud Rana Li Li Steven W.Su | 2018 | IEEE/CAA Journal of Automatica Sinica2018，5，2： | 4 |
| 2 | Flooding and its relationship with land cover change, population growth, and road density显示文摘Bangladesh experiences frequent hydro-climatic disasters such as flooding.These disasters are believed to be associated with land use changes and climate variability.However,identifying the factors that lead to flooding is challenging.This study mapped flood susceptibility in the northeast region of Bangladesh using Bayesian regularization back propagation(BRBP)neural network,classification and regression trees(CART),a statistical model(STM)using the evidence belief function(EBF),and their ensemble models(EMs)for three time periods(2000,2014,and 2017).The accuracy of machine learning algorithms(MLAs),STM,and EMs were assessed by considering the area under the curve—receiver operating characteristic(AUC-ROC).Evaluation of the accuracy levels of the aforementioned algorithms revealed that EM4(BRBP-CART-EBF)outperformed(AUC>90%)standalone and other ensemble models for the three time periods analyzed.Furthermore,this study investigated the relationships among land cover change(LCC),population growth(PG),road density(RD),and relative change of flooding(RCF)areas for the period between 2000 and 2017.The results showed that areas with very high susceptibility to flooding increased by 19.72%between 2000 and 2017,while the PG rate increased by 51.68%over the same period.The Pearson correlation coefficient for RCF and RD was calculated to be 0.496.These findings highlight the significant association between floods and causative factors.The study findings could be valuable to policymakers and resource managers as they can lead to improvements in flood management and reduction in flood damage and risks. | Mahfuzur Rahman Chen Ningsheng Golam Iftekhar Mahmud Md Monirul Islam Hamid Reza Pourghasemi Hilal Ahmad Jules Maurice Habumugisha Rana Muhammad Ali Washakh Mehtab Alam Enlong Liu Zheng Han Huayong Ni Tian Shufeng Ashraf Dewan | 2021 | Geoscience Frontiers2021，12，6： | 3 |

| 11 | Hepatic Histoplasmosis: An Update显示文摘Histoplasma capsulatum is the most common cause of en-demic mycosis in developing countries. It is a self-limited and asymptomatic disease in immunocompetent individu-als but remains a frequent cause of opportunistic infection in patients with compromised immune status. Liver in-volvement as a part of disseminated histoplasmosis is well known. However, liver infection as a primary manifestation of histoplasmosis without evidence of primary lung involve-ment is rare. In conclusion, clinicians should be aware of isolated histoplasmosis affecting the hepatobiliary system, and careful evaluation is warranted to confirm the diagno-sis. Given the appropriate clinical context, histoplasmosis should be considered in both immunocompetent and immu-nocompromised patients, regardless of pulmonary symp-toms, in non endemic as well as endemic areas. | Maimuna Sayeed Md Benzamin Luthfun Nahar Masud Rana Aisharza Sultana Aishy | 2022 | Journal of Clinical and Translational Hepatology2022，10，4： | 0 |
| 12 | Stature estimation from footprint measurements in Bangladeshi adults显示文摘The estimation of stature is very important in forensic investigation,as it provides useful data that can narrow the pool of potentially matching identities.The purpose of this study was to develop formulae for the estimation of stature from footprint measurements in Bangladeshi adults.This study included 118 randomly selected men and 130 randomly selected women,all aged 18–50 years.From each participant,stature and six footprint measurements were taken by means of standard measurement techniques.Footprint measurements were found to be positively correlated with stature.Stature was estimated by using linear regression equations.The right T1 length in men(R:þ0.587,R^(2):0.345)and the right T2 length in women(R:þ0.506,R^(2):0.256)were the most reliable individual estimators of stature.However,when data were combined for both sexes,the right T2 length was identified as the most reliable estimator of stature,with higher values of R(þ0.792)and R^(2)(0.627).In conclusion,human stature can be successfully estimated by using footprint measurements;this finding can be applied in forensic research and investigation. | Md Asadujjaman Md Harun Or Rashid Md Sohel Rana Md Mosharraf Hossain | 2022 | Forensic Sciences Research2022，7，2： | 0 |
| 13 | Performance of Islamic and conventional stock indices:empirical evidence from an emerging economy显示文摘Background:This study aims to investigate the extent to which the conditional volatilities of both Shari’ah compliant stock and conventional stock are related to those of interest rate and exchange rate in the emerging economy of Pakistan.Methods:We used KMI 30 and KSE 100 indices for Islamic and conventional stock for the period of July 2008 to November 2013.We employed Generalized Autoregressive Conditional Heteroskedastic in the mean(GARCH-M)model.This framework relaxes constancy assumption of classical linear regression(CLRM)model and allows exchange rate and interest rate volatility to evolve over time.The GARCHM framework also reveals results about risk-return trade-off in the context of both Islamic and conventional stock indices.Results:The findings show positive and statistically significant effect of interest rate volatility on KSE-100,whereas KMI-30 remains unaffected by the same.Exchange rate volatility is found to be significant for both conventional and Islamic indices.The relationship of risk coefficient(γ)and stocks returns,as expected,is positive and statistically significant for both KMI-30 and KSE-100.This result is consistent with the theory of risk-return trade-off.The results of parametric t-test show significant difference between returns of both indices.This implies that Shari’ah compliant stock index(KMI-30)of Pakistan underperforms its conventional counterpart.Conclusion:By using different performance measures(Sharp ratio,Jensen alpha,Treynor ratio),this study also investigates the hypothesis that Islamic stock index has inferior performance compared with unscreened conventional counterparts due to availability of a smaller investment universe,increased monitoring costs,and limited diversification. | Md Ejaz Rana Waheed Akhter | 2015 | Financial Innovation2015，1，1： | 0 |
