| 1 | H_∞ Consensus Control of Discrete-Time Multi-Agent Systems Under Network Imperfections and External Disturbance显示文摘This paper presents a distributed control protocol for consensus control of multi-agent systems(MASs) under external disturbances and network imperfections, including communication delay and random packet dropout. To comply with the discrete nature of networked systems, in contrast to most of the existing work for MASs under network imperfections,the agents are modeled by discrete-time dynamics. The communication network is considered to be undirected, its delay is considered to be time-varying but bounded, and its packet dropout is modeled by a Bernoulli distributed white sequence.Sufficient conditions in terms of linear matrix inequalities(LMIs)for asymptotic mean-square consensus stability are derived under network imperfections without considering external disturbances.A desired disturbance attenuation level in the presence of both external disturbances and network imperfections is also provided.A simulation example is given to verify the effectiveness of the proposed approach in coping with network imperfection and disturbances. | Arezou Elahi Alireza Alfi Hamidreza Modares | 2019 | IEEE/CAA Journal of Automatica Sinica2019，6，3： | 12 |
| 2 | 熔化和热处理条件对A356铝合金冲击韧性的影响(英文)显示文摘研究A356铝合金在非热处理和T6热处理条件下经熔化处理过程中的晶粒细化和改性后的显微组织和冲击性能。通过添加Al-10%Sr和Al-5Ti-1B中间合金分别实现改性和晶粒细化。为了重点突出上述处理的影响,所有的铸造参数都保持不变。结果表明:共晶硅形貌是控制合金冲击行为的主要参数。因此,铸态合金的晶粒细化不能像改性一样改善其冲击韧性。然而,相对于单个处理,同时进行晶粒细化和改性能提供更高的冲击韧性。合金的T6热处理在所有的熔化处理条件下都改善了冲击韧性,这与共晶硅颗粒的进一步改性有关。为证明这些结果并阐明其机制,使用三点弯曲实验和金属断面的显微观察来阐述合金冲击韧性的改善。 | M.AMNE ELAHI S.G.SHABESTARI | 2016 | Transactions of Nonferrous Metals Society of China2016，26，4： | 8 |
| 3 | Multi-objective design optimization of composite submerged cylindrical pressure hull for minimum buoyancy and maximum buckling load capacity显示文摘This paper presents the design optimization of composite submersible cylindrical pressure hull subjected to 3 MPa hydrostatic pressure.The design optimization study is conducted for cross-ply layups[0_(s)/90_(t)/0_(u)],[0_(s)/90_(t)/0_(u)]s,[0_(s)/90_(t)]s and[90_(s)/0_(t)]s considering three uni-directional composites,i.e.Carbon/Epoxy,Glass/Epoxy,and Boron/Epoxy.The optimization study is performed by coupling a Multi-Objective Genetic Algorithm(MOGA)and Analytical Analysis.Minimizing the buoyancy factor and maximizing the buckling load factor are considered as the objectives of the optimization study.The objectives of the optimization are achieved under constraints on the Tsai-Wu,Tsai-Hill and Maximum Stress composite failure criteria and on buckling load factor.To verify the optimization approach,optimization of one particular layup configuration is also conducted in ANSYS with the same objectives and constraints. | Muhammad Imran Dong-yan Shi Li-li Tong Ahsan Elahi Hafiz Muhammad Waqas Muqeem Uddin | 2021 | Defence Technology(防务技术)2021，17，4： | 2 |

| 5 | A Randomized,Double Blinded,Placebo-Controlled Clinical Trial of Silymarin in Ulcerative Colitis显示文摘Objective:To evaluate the clinical efficacy of silymarin in ulcerative colitis(UC) patients.Methods:A randomized double blinded placebo-controlled clinical trial was conducted in 80 UC patients whose disease had been documented and were in remission state between September 2009 and October 2010.Patients were assigned to silymarin group(42 cases) and placebo group(38 cases) using a random number table.Either silymarin(140 mg) or placebo(lactose mono-hydrate,corn starch magnesium stearate) tablets were given once daily for 6 months along with their standard therapy.The efficacies were assessed by disease activity index(DAI),frequency difference of the disease flare-up,and paraclinical data.Results:Ten patients(4 in the silymarin group due to nausea and 6 in the placebo group due to disease flare-up and abdominal pain)discontinued the study.An improvement in hemoglobin level(11.811.6 g/dL vs.13.4 ±1.2 g/dL,P<0.05)and erythrocyte sedimentation rate(23.7±11.5 mm/h vs.10.8±3.2 mm/h,P<0.05) was observed in the silymarin group but not in the placebo group.DAI significantly decreased in the silymarin group and reached from 11.3 ±3.5 to 10.7 ±2.8(P<0.05).Thirty-five out of 38 patients in the silymarin group were in complete remission with no flare-up after 6 months as compared to 21 out of 32 patients in the placebo group(P=0.5000).Conclusion:Silymarin as a natural supplement may be used in UC patients to maintain remission. | Mansoor Rastegarpanah Reza Malekzadeh Homayoun Vahedi Maryam Mohammadi Elham Elahi Meghedi Chaharmahali Tahereh Safarnavadeh Mohammad Abdollahi | 2015 | Chinese Journal of Integrative Medicine2015，21，12： | 2 |

| 8 | Optimal Cooperative Spectrum Sensing Based on Butterfly Optimization Algorithm显示文摘Since the introduction of the Internet of Things(IoT),several researchers have been exploring its productivity to utilize and organize the spectrum assets.Cognitive radio(CR)technology is characterized as the best aspirant for wireless communications to augment IoT competencies.In the CR networks,secondary users(SUs)opportunistically get access to the primary users(PUs)spectrum through spectrum sensing.The multipath issues in the wireless channel can fluster the sensing ability of the individual SUs.Therefore,several cooperative SUs are engaged in cooperative spectrum sensing(CSS)to ensure reliable sensing results.In CSS,security is still a major concern for the researchers to safeguard the fusion center(FC)against abnormal sensing reports initiated by the malicious users(MUs).In this paper,butterfly optimization algorithm(BOA)-based soft decision method is proposed to find an optimized weighting coefficient vector correlated to the SUs sensing notifications.The coefficient vector is utilized in the soft decision rule at the FC before making any global decision.The effectiveness of the proposed scheme is compared for a variety of parameters with existing schemes through simulation results.The results confirmed the supremacy of the proposed BOA scheme in both the normal SUs’environment and when lower and higher SNRs information is carried by the different categories of MUs. | Noor Gul Saeed Ahmed Atif Elahi Su Min Kim Junsu Kim | 2022 | Computers, Materials & Continua2022，，4： | 1 |
