Sport is one of the activities of human being where cooperative, competitive, self-learning and interactive environment helps in the overall improvement of the performance. These learning processes are very effective to regulate the players in a good direction as well as to enhance their capability of exploring the new techniques. Particle Swarm Optimization (PSO) is a popular stochastic optimization algorithm, used for solving real-world engineering problems. However, it usually suffers from local confinement and easily loses its diversity. In this paper, we have integrated the properties of sports with PSO algorithm and proposed an efficient player selection strategy based diversified PSO (EPS-dPSO), which improves the fitness and robustness of the technique without compromising the computational complexity of the algorithm. The properties of player selection is adopted to enhance the diversity within the search phase as well as to incorporate intense searching of the space. We have comprehensively evaluated the performance of proposed EPS-dPSO by applying it on standard benchmark problems. Experimental result shows that it not only tracks the global optimum within the small search interval but also able to obtain good result for large and asymmetrical search space and also insensitive to initialization of the problems. Further, tests are carried out on the benchmark functions from CEC2005, the large dimensional problems of CEC2008 and some real world problems from CEC2011. All the experimental results indicate the effectiveness and efficiency of the proposed EPS-dPSO compared to other traditional algorithms. © 2017 Elsevier Inc.

The practice of sport, intended not just as a physical activity performed exclusively for athletic competition, represents a key element for growth on an emotional and social level. Practicing sports can help to enhance one’s self- and body awareness through multidimensional dynamic and ludic activity. In this context, sport becomes an educational and training tool, and is often a forerunner of social change. Sports practice combining physical activity with recreational activity, can, in fact, promote health and longevity, as well as physical and psychological wellbeing. As highlighted by the European Union, sport is also a source of social inclusion, and an excellent tool for the integration of minorities and groups at risk of social exclusion. © EuroMediterranean Biomedical Journal 2017.

Azadirachta indica, used in antidiabetic herbal drugs, was reported to contain α-glucosidase inhibitor. Bioassay guided purification characterized the inhibitor as nimbidiol (a diterpenoid), present in root and stem-bark of the tree. Nimbidiol inhibited intestinal (mammalian) maltase-glucoamylase, sucrase-isomaltase, lactase, trehalase and fungal α-glucosidases. Nimbidiol showed a mixed competitive inhibition on intestinal carbohydrases. IC50, Ki and Ki′ (μM) were 1.35 ± 0.12, 0.08 ± 0.01, 0.25 ± 0.11, respectively, for maltase-glucoamylase (maltotetraose as substrate). Nimbidiol was more potent inhibitor of isomaltase (IC50 0.85 ± 0.035 μM), lactase (IC50 20 ± 1.33 μM) and trehalase (IC50 30 ± 1.75 μM) than acarbose, voglibose, salacinol, kotalanol and mangiferin. Ki and Ki′ values (μM) for intestinal sucrase were 0.7 ± 0.12 and 1.44 ± 0.65, respectively. Development of nimbidiol as an antidiabetic drug appears to be promising because of broad inhibition spectrum of intestinal glucosidases and easy synthesis of the molecule. © 2013 Informa UK, Ltd.

In the present study, the variation of total lateral pressure with depth against strutted retaining wall from outside the excavation area (active) and below the excavation area (passive) are investigated numerically for different types of retained soil layer (cohesionless), wall thickness and depth of embedment of the wall. The net lateral earth pressure calculated numerically has been validated against that measured in the model test of a singly propped (strutted) embedded retaining wall. The validated numerical model is used to investigate the influence of various factors on the lateral earth pressure. It is found that the passive resistance increases with the bulk density of the retained cohesionless soil and the depth of embedment of the retaining wall, but it is independent of the thickness of the wall. Moreover, it is inferred that the total active pressure increases with depth of embedment (or total depth) of the wall and decreases with the increase in bulk density of sand. Relations between normalised lateral pressures with normalised depth are also established to provide guidance to the analysis and design of the strutted system for a particular soil condition, thickness and depth of embedment (total depth) of the wall. © 2017 Informa UK Limited, trading as Taylor & Francis Group

Composite shell structures are extensively used in aerospace, civil, marine and other engineering applications. In practical civil engineering applications, the necessity of covering large column free open areas is often an issue and hyperbolic paraboloid shells are used as roofing units. Quite often, to save weight and also to provide a facility for inspection, cutouts are provided in shell panels. The paper considers free vibration characteristics of stiffened composite hyperbolic paraboloid shell panel with cutout in terms of natural frequency and mode shapes. A finite element code is developed for the purpose by combining an eight noded curved shell element with a three noded curved beam element. The size of the cutouts and their positions with respect to the shell centre are varied for different edge conditions to arrive at a set of inferences of practical engineering significances. © Published under licence by IOP Publishing Ltd.

Composite films containing silver (Ag) nanoparticles embedded in amorphous diamond-like carbon (Ag–DLC) matrix have been deposited on glass and Si (100) substrates using r.f. capacitatively coupled plasma chemical vapour deposition (rf-CVD). Ag content in the DLC films varies with the relative amount of argon in the methane and argon gas mixture during the plasma growth. The film thickness ranges from 50 nm to 105 nm. The sp2/sp3 ratio in the DLC films decreases with the incorporation of nanocrystalline silver. A considerable amount, of about 99% residual stress reduction in Ag–DLC films has been demonstrated through theoretical calculation with the help of experimental optical absorption spectra. The results are verified by experimental nano-mechanical property evolution using nano-indentation. The related residual compressive stress reduction in the Ag–DLC composite films is attributed to the addition of uniformly dispersed nanocrystalline silver nanoparticles in the DLC matrix and the corresponding relative sp2/sp3 ratio variation. © 2017 Elsevier B.V.

In this paper an Empirical Mode Decomposition (EMD) based ECG signal enhancement and QRS detection algorithm is proposed. Being a non-invasive measurement, ECG is prone to various high and low frequency noises causing baseline wander and power line interference, which act as a source of error in QRS and other feature extraction. EMD is a fully adaptive signal decomposition technique that generates Intrinsic Mode Functions (IMF) as decomposition output. Here, first baseline wander is corrected by selective reconstruction based slope minimization technique from IMFs and then high frequency noise is removed by eliminating a noisy set of lower order IMFs with a statistical peak correction as high frequency noise elimination is accompanied by peak deformation of sharp characteristic waves. Then a set of IMFs are selected that represents QRS region and a nonlinear transformation is done for QRS enhancement. This improves detection accuracy, which is represented in the result section. Thus in this method a single fold processing of each signal is required unlike other conventional techniques. © 2011 Elsevier Ltd.

A novel integrated immobilized enzyme-reactor system involving a continuous stirred tank reactor with two packed bed reactors in series was developed for the continuous production of biodiesel. The problem of methanol solubility into oil was solved by introducing a stirred tank reactor to dissolve methanol into partially converted oil. This step made the process perfectly continuous without requiring any organic solvent and intermittent methanol addition in the process. The substrate feeding rate of 0.74. mL/min and enzyme loading of 0.75. g per reactor were determined to be optimum for maximum biodiesel yield. The integrated continuous process was stable up to 45 cycles with biodiesel productivity of 137.2. g/L/h, which was approximately 5 times higher than solvent free batch process. In comparison with the processes reported in literature using expensive Novozyme 435 and hazardous organic solvent, the present process is completely green and perfectly continuous with economic and environmental advantages. © 2013 Elsevier Ltd.

The recent discovery of nonzero θ13 (equal to Cabbibo angle θC up to a factor of √2), the masses of supersymmetric particles > TeV from LHC data, and the sum of three active neutrino masses Σimνi < 1 eV from the study of large scale structure of the universe motivate to study whether quark and lepton mixing have the same origin at the grand unification scale. We find that both results from neutrino experiments and LHC are complementary in quark-lepton unified model. A new constraint on SUSY parameters appears from electroweak symmetry breaking with a new correlation between the lower bounds on sparticle masses and the upper bound on Σimνi. In addition, we find that only μ > 0 (which is favored by (g - 2) of muon) is allowed and mq̄,ī > TeV if Σi νi < 1 eV. On the other hand, a small change in lower limit on θ13 from zero leads to a large increase in lower limits on sparticles masses (> 2 TeV), which are also the bounds if recently discovered boson at LHC with mass around 125 GeV is the Higgs boson. © 2013 The Author.
