A ROUGH sET APPROACH TO FEATURE sELECTION BAsED ON sCATTER sEARCH METAHEURIsTIC

引用

Journal of systems science & Complexity 2014年第1期27卷 157-168页

作者： WANG Jue ZHANG Qi ABDEL-rahmaN Hedar ABDEL-monem M Ibrahim Center for Forecasting science Academy of Mathematics and System Science Chinese Academy of ScienceBeijing 100190 China. Department of Computer science Faculty of Computers and Information Assiut University Assiut 71516Egypt.

Rough set theory is an effective method to feature selection, which has recently fascinated many researchers. The essence of rough set approach to feature selection is to find a subset of the original features. It is, however, an NP-hard problem finding a minimal subset of the features, and it is necessary to investigate effective and efficient heuristic algorithms. This paper presents a novel rough set approach to feature selection based on scatter search metaheuristic. The proposed method, called scatter search rough set attribute reduction （ssAR）, is illustrated by 13 well known datasets from UCI machine learning repository. The proposed heuristic strategy is compared with typical attribute reduction methods including genetic algorithm, ant colony, simulated annealing, and Tabu search. Computational results demonstrate that our algorithm can provide efficient solution to find a minimal subset of the features and show promising and competitive performance on the considered datasets.

Postoperative Analgesia Following Caesarean section: Intravenous Patient Controlled Analgesia Versus Conventional Continuous Infusion

引用

Open Journal of Anesthesiology 2012年第4期2卷 120-126页

作者： samina Ismail Gauhar Afshan abdul monem Aliya Ahmed Department of Anaesthesia The Aga Khan University Karachi Pakistan

Background: Management of postoperative pain after caesarean section (C/s) requires a balance between pain relief and undesirable side effects of drugs and technique. In order to improve postoperative pain management after caesarean section, we compared intravenous patient controlled analgesia (IV-PCA) with our current hospital practice, which is continuous opioid infusion. Method: We enrolled one hundred and twenty patients in our prospective randomized trial after an uneventful elective caesarean section under spinal anaesthesia. All patients received 0.5 mg/kg bolus of pethidine on first complaint of pain or at 120 minutes after institution of spinal anaesthesia. Depending upon the randomization, Group P received IV-PCA with 0.15 mg/kg bolus pethidine with 10-minute lockout and Group C received continuous pethidine infusion at a rate of 0.15 mg/kg/hr. statistical analysis: For qualitative variables means and standard deviations were computed and analyzed by T-test, Mann Whitney U test and repeated measures ANOVA. Frequency and percentages were computed for qualitative data and analyzed by Chi-square and Fischer exact test. A p-value of less than 0.05 was treated as significant. Results: The numeric rating score for pain, need for rescue analgesia and incidence of nausea and vomiting was significantly lower (p-value s compared to continuous infusion group at 6, 12 and 24 hours postoperatively, 98% of the patients were satisfied with pain management in Group P as compared to 70% (p sion: Our results showed improved pain control, less need for rescue analgesia for breakthrough pain, lower incidence of nausea and vomiting and greater patient satisfaction with IV-PCA. In the absence of preservative free narcotics for intrathecal use, postoperative pain management can be significantly improved by using IV-PCA instead of continuous opioid infusion in patients undergoing caesarean section.

Optimized Design and Analysis of single-Phase and Three-Phase Inverters for Efficient Power Conversion: A Comparative study

引用

Journal of Computer and Communications 2023年第8期11卷 71-95页

作者： Ashik Alam Md. abdul monem Kazi Khairul Islam Department of Electrical and Electronic Engineering Bangladesh Army University of Engineering and Technology (BAUET) Natore Bangladesh Department of Mechanical Engineering Bangladesh Army University of Engineering and Technology (BAUET) Natore Bangladesh

A large amount of switching loss occurs in the inverter. From this point of view, an inverter design should be optimized for which size and cost will be minimum along with increasing efficiency. The main aim of this paper is the analysis and development of single-phase and three-phase inverter to design with MOsFET and IGBT as power elements by sinusoidal pulse width modulation (sPWM) technique using MATLAB simulink software and compare their difference with the practical inverter. This work proposes different multilevel stages for the cascaded H-Bridge inverter to enhance the output voltages. Then compare their performance, harmonic distortion, and frequency spectrum. The hardware of an inverter circuit has been developed using the sG3524 microcontroller. The main goal of this design is to generate a sine wave with fewer harmonics, while keeping the cost and complexity of the circuit low. The designed inverter has undergone testing with different AC loads and is primarily intended for low-power applications, as lamps, fans, and chargers. This design aims to provide a reliable and efficient inverter solution for these specific applications.
