Theoretical modelling of laminated composite plates

Formulation of appropriate governing equations, simpler than the three-dimensional equations of elasticity yet capable of predicting, fairly accurately, all important response parameters such as stress and strain, is attempted in modelling a structural component. Several theoretical models are available in the literature for the analyses of plates. The emergence of fibre-reinforced plastics as an attractive form of structural construction, added a new complexity to the modelling considerations of laminates by requiring the estimation of the interlaminar stresses and strains. In this paper, modelling considerations of laminated composite plates are discussed. The classical laminated plate theory and higher-order shear deformation models are reviewed to bring out their interlaminar stress predictive capabilities, and some new modelling possibilities are indicated. This work has been supported by the Aeronautics Research and Development Board, Ministry of Defence, Government of India.     

Short-term decisions under long-term uncertainty

The behaviour of future policy-makers substantially influences future greenhouse gas emissions. Uncertainty about the motives of future policy-makers may thus strongly influence the climate policy strategies of current policy-makers. Analytical and numerical analyses in this paper confirm this hypothesis. If current policy-makers want to constrain emissions accumulated over a prolonged period of time, and if future policy-makers tend, with a certain chance, to a less ambitious climate policy, then current policy-makers should intensify their efforts to reduce emissions and the cost of emission reduction. In this setting, if current policy-makers want to meet a cumulative emission contraint in expectation, then the preferred policy trajectory does not qualitatively deviate from one suggested by a standard cost-effective trajectory. If, however, the constraint is to be met with a certain probability, then the importance of early action is enhanced relative to that of postponed action. Costs substantially increase if current policy-makers want to set long-term goals without the full cooperation of future policy-makers.

Policy impacts on pedagogical practice and ICT use: an exploration of the results from SITES 2006

The Second Information Technology in Education Study (SITES) 2006 results reveal that principals' perceived presence of lifelong learning‐related pedagogical activities in their schools had changed markedly since the same data was collected in 1998 in SITES‐M1. More intriguing was the fact that the directions of the changes were quite different depending on the education systems concerned – many of the Asian countries reported very high increases while some of the European countries reported large drops over the same 8‐year period. This paper reports statistical evidence that the observed ‘pendulum swing’ reflects actual changes in teaching practices in these countries. Exploratory multilevel analyses results consistently show that national means of principals' vision can be used as a system‐level indicator predicting national means of pedagogical orientations in schools several years later. These findings also indicate the possibility of the ‘pendulum effect’ being a consequence of system‐level policy differences in the countries participating in the two SITES studies.     

A comparison study of the capacitive behavior for sol-gel-derived and co-annealed ruthenium-tin oxide composites

The electrochemical behavior of mixed Ru-Sn oxides fabricated by a modified sol-gel process and a co-annealing method are systematically compared (using cyclic voltammetric and electrochemical impedance spectroscopic analyses), for the application of supercapacitors. Influences of annealing temperature and time on the specific capacitance and textural properties of oxides are also studied. Based on the quasi-linear dependence of voltammetric current density on the scan rate of CV (from 25 to 500 mV s⁻¹), the lowest proton diffusion resistance, and the high-frequency (∼426 Hz) capacitive responses of the co-annealed composite (RTOC_co) as well as its ease in composition control, co-annealing of hydrous RuO₂ and SnO₂ at 200 °C for 2 h is recommended as a promising and practical method for preparing mixed oxides in the supercapacitor application.
