stretchable and conformal humidity sensors that can be attached to the human body for continuously monitoring the humidity of the environment around the human body or the moisture level of the human skin can play an important role in electronic skin and personal healthcare applications. However, most stretchable humidity sensors are based on the geometric engineering of non-stretchable components and only a few detailed studies are available on stretchable humidity sensors under applied mechanical deformations. In this paper, we propose a transparent, stretchable humidity sensor with a simple fabrication process, having intrinsically stretchable components that provide high stretchability, sensitivity, and stability along with fast response and relaxation time. Composed of reduced graphene oxide-polyurethane composites and an elastomeric conductive electrode, this device exhibits impressive response and relaxation time as fast as 3.5 and 7 s, respectively. The responsivity and the response and relaxation time of the device in the presence of humidity remain almost unchanged under stretching up to a strain of 60% and after 10,000 stretching cycles at a 40% strain. Further, these stretchable humidity sensors can be easily and conformally attached to a finger for monitoring the humidity levels of the environment around the human body, wet objects, or human skin.

A Novel PsO Algorithm for Optimal Production Cost of the Power Producers with Transient stability Constraints

引用

Journal of Electromagnetic Analysis and Applications 2009年第4期1卷 265-274页

作者： M. ANITHA s. subramanian r. GNANADAss 不详

The application of a novel Particle swarm Optimization (PsO) method called Fitness Distance ratio PsO (FDr PsO) algorithm is described in this paper to determine the optimal power dispatch of the Independent Power Producers (IPP) with linear ramp model and transient stability constraints of the power producers. Generally the power producers must respond quickly to the changes in load and wheeling transactions. Moreover, it becomes necessary for the power producers to reschedule their power generation beyond their power limits to meet vulnerable situations like credible contingency and increase in load conditions. During this process, the ramping cost is incurred if they violate their permissible elastic limits. In this paper, optimal production costs of the power producers are computed with stepwise and piecewise linear ramp rate limits. Transient stability limits of the power producers are also considered as addi-tional rotor angle inequality constraints while solving the Optimal Power Flow (OPF) problem. The proposed algo-rithm is demonstrated on practical 10 bus and 26 bus systems and the results are compared with other optimization methods.

N6-Methyladenosine(m6A)is the most common and abundant modification of rNA molecules,including mrNAs,microrNAs(mirNAs),and long noncoding rNAs(lncrNAs).1 The m6A modification is catalyzed and dynamically regulated by recently discovered enzymes termed“writers”(methyltransferases including METTL3,METTL14,and WTAP),“erasers”(demethylases including FTO and ALkBH5)and“readers”(m6A-binding proteins including YTHDC1,YTHDC2,YTHDF1,YTHDF2,and YTHDF3).These modifications were recently shown to be involved in the regulation of different biological processes.

The effect of mechanical and tribological behaviour of aluminium alloy(Al-si10-Mg) with sugarcane bagasse ash and silicon carbide reinforced metal matrix composites were investigated. Al-si10-Mg alloy reinforced with 9 wt.% of treated sugarcane bagasse ash particles of size(silicon carbide particles of size(re fabricated using the stir casting method. Morphological analysis was done using scanning electron microscopy to access the distribution of reinforcement particles in the matrix alloy. Tensile, hardness, and impact strengths were increased with an increase in weight fraction of siC reinforcement particles in the aluminium alloy, while the ductility was decreased. Pin-on-disc dry sliding wear test was carried out with 10, 20 and 30 N loads with a sliding speed of 10 m·s-1 for a constant time period of 20 min to predict the wear behaviour of the developed composites. Worn surfaces of the wear-tested specimens and fracture morphology structure of the tensile-tested specimens were analysed. results show that the composites reinforced with sugarcane bagasse ash and silicon carbide particles exhibit superior wear resistance.

GPs： a constraint-based gene position procurement in chromosome for solving large-scale multiobjective multiple knapsack problems

引用

Frontiers of Computer science 2018年第1期12卷 101-121页

作者： Jayanthi MANICAssAMY Dinesh kArUNANIDHI sujatha POTHULA Vengattaraman THIrUMAL Dhavachelvan PONNUrANGAM subramanian rAMALINGAM Department of Computer science Pondicherry University Pondicherry 605 014 India

The multiple knapsack problem （MkP） forms a base for resolving many real-life problems. This has also been considered with multiple objectives in genetic algorithms （GAs） for proving its efficiency. GAs use self- adaptability to effectively solve complex problems with constraints, but in certain cases, self-adaptability fails by converging toward an infeasible region. This pitfall can be resolved by using different existing repairing techniques; however, this cannot assure convergence toward attaining the optimal solution. To overcome this issue, gene position-based suppression （GPs） has been modeled and embedded as a new phase in a classical GA. This phase works on the genes of a newly generated individual after the recombination phase to retain the solution vector within its feasible region and to im- prove the solution vector to attain the optimal solution. Genes holding the highest expressibility are reserved into a subset, as the best genes identified from the current individuals by re- placing the weaker genes from the subset. This subset is used by the next generated individual to improve the solution vec- tor and to retain the best genes of the individuals. Each gene＇s positional point and its genotype exposure for each region in an environment are used to fit the best unique genes. Further, suppression of expression in conflicting gene＇s relies on the requirement toward the level of exposure in the environment or in eliminating the duplicate genes from the *** MkP benchmark instances from the Or-library are taken for the experiment to test the new model. The outcome por- trays that GPs in a classical GA is superior in most of the cases compared to the other existing repairing techniques.

rapid adsorption of toxic Pb(Ⅱ) ions from aqueous solution using multiwall carbon nanotubes synthesized by microwave chemical vapor deposition technique

引用

Journal of Environmental sciences 2016年第7期28卷 143-155页

作者： Nabisab Mujawar Mubarak Jaya Narayan sahu Ezzat Chan Abdullah Natesan subramanian Jayakumar Department of Chemical Engineering Faculty of Engineering and Science Curtin University Sarawak Department of Chemical Engineering Faculty of Engineering University of Malaya Petroleum and Chemical Engineering Programme Area Faculty of Engineering Institut Teknologi Brunei Malaysia–Japan International Institute of Technology Universiti Teknologi Malaysia Jalan Semarak

Multiwall carbon nanotubes（MWCNTs） were synthesized using a tubular microwave chemical vapor deposition technique, using acetylene and hydrogen as the precursor gases and ferrocene as catalyst. The novel MWCNT samples were tested for their performance in terms of Pb（Ⅱ）binding. The synthesized MWCNT samples were characterized using Fourier Transform Infrared（FT-Ir）, Brunauer, Emmett and Teller（BET）, Field Emission scanning Electron Microscopy（FEsEM） analysis, and the adsorption of Pb（Ⅱ） was studied as a function of p H,initial Pb（Ⅱ） concentration, MWCNT dosage, agitation speed, and adsorption time, and process parameters were optimized. The adsorption data followed both Freundlich and Langmuir isotherms. On the basis of the Langmuir model, Qmaxwas calculated to be 104.2 mg/g for the microwave-synthesized MWCNTs. In order to investigate the dynamic behavior of MWCNTs as an adsorbent, the kinetic data were modeled using pseudo first-order and pseudo second-order equations. Different thermodynamic parameters, viz., ΔH0, Δs0and ΔG0were evaluated and it was found that the adsorption was feasible, spontaneous and endothermic in nature. The statistical analysis revealed that the optimum conditions for the highest removal（99.9%） of Pb（Ⅱ） are at p H 5, MWCNT dosage 0.1 g, agitation speed 160 r/min and time of 22.5 min with the initial concentration of 10 mg/L. Our results proved that microwave-synthesized MWCNTs can be used as an effective Pb（Ⅱ） adsorbent due to their high adsorption capacity as well as the short adsorption time needed to achieve equilibrium.
