Probabilistic stability assessment of slopes using high dimensional model representation     

Rajib Chowdhury  B.N. Rao 《Computers and Geotechnics》2010,37(7-8):876-884

This paper presents a new computational tool for probabilistic stability assessment of earth slopes/embankments. The method involves high dimensional model representation (HDMR) that facilitates lower dimensional approximation of the original limit state, response surface generation of HDMR component functions, and Monte Carlo simulation. HDMR is a general set of quantitative model assessment and analysis tools for capturing the high-dimensional relationships between sets of input and output model variables. It is a very efficient formulation of the system response, if higher-order variable correlations are weak, allowing the physical model to be captured by the first few lower-order terms. Once the approximate form of the original limit state is defined, the failure probability can be obtained by statistical simulation. Results of four numerical examples indicate that the proposed method provides accurate and computationally efficient estimates of the failure probability of earth slopes/embankments.  相似文献   

Hydroclimatic teleconnection between global sea surface temperature and rainfall over India at subdivisional monthly scale     

Rajib Maity  D. Nagesh Kumar 《水文研究》2007,21(14):1802-1813

It is well established that sea surface temperature (SST) plays a significant role in the hydrologic cycle in which precipitation is the most important part. In this study, the influence of SST on Indian subdivisional monthly rainfall is investigated. Both spatial and temporal influences are investigated. The most influencing regions of sea surface are identified for different subdivisions and for different overlapping seasons in the year. The relative importance of SST, land surface temperature (LST) and ocean–land temperature contrast (OLTC) and their variation from subdivision to subdivision and from season to season are also studied. It is observed that LST does not show much similarity with rainfall series, but, in general, OLTC shows relatively higher influence in the pre‐monsoon and early monsoon periods, whereas SST plays a more important role in late‐ and post‐monsoon periods. The influence of OLTC is seen to be mostly confined to the Indian Ocean region, whereas the effect of SST indicates the climatic teleconnection between Indian regional rainfall and climate indices in Pacific and Atlantic Oceans.

Hornblende-dehydration melting in mafic rocks and the link between massif-type charnockite and associated granulites,Eastern Ghats Granulite Belt,India   总被引：1，自引：0，他引：1  

Rajib?Kar  S.?BhattacharyaEmail author  J.?W.?Sheraton 《Contributions to Mineralogy and Petrology》2003,145(6):707-729

A massif-type (intrusive) charnockite body in the Eastern Ghats granulite belt, India, is associated with hornblende-bearing mafic granulite, two-pyroxene granulite and enderbitic granulite. The charnockite is characterised by pervasive gneissic foliation (S₁). This is axial planar to the folded layers of hornblende-bearing mafic granulite (F₁ folds), indicating that the granulite protoliths were present before the development of S₁. Two-pyroxene granulite and enderbitic granulite occur as lenticular patches disposed along the foliation and hence could be syngenetic to S₁. The tonalitic to granodioritic, metaluminous to weakly peraluminous compositions and relatively high Sr/Rb of the charnockite are consistent with its derivation by partial melting of a mafic protolith. Strong Y depletion, lack of Sr depletion and strongly fractionated REE patterns with high (La/Yb)_N ratio, but relatively lower HREE (Gd/Lu) fractionation with marked positive Eu anomalies, suggest major residual hornblende (as well as garnet), but not plagioclase, consistent with the hornblende dehydration melting in the source rocks. Such a residual mineralogy is broadly similar to those of some of the hornblende-bearing mafic granulite inclusions, which have compositional features indicative of a restitic nature. Quantitative modelling supports an origin for the charnockite melts by partial melting of a hornblende-rich mafic granulite source, although source heterogeneity is very likely given the rather variable trace element contents of the charnockite. The whole-rock and mineral compositions of the two-pyroxene granulites and enderbitic granulites are consistent with them representing peritectic phase segregations of hornblende-dehydration melting. A clockwise P-T path implies that melting could have occurred in thickened continental crust undergoing decompression.Editorial responsibility: T.L. Grove  相似文献   

Testing isotropy of cosmic microwave background radiation     

Pramoda Kumar Samal  Rajib Saha  Pankaj Jain  John P. Ralston 《Monthly notices of the Royal Astronomical Society》2008,385(4):1718-1728

We introduce new symmetry-based methods to test for isotropy in cosmic microwave background (CMB) radiation. Each angular multipole is factored into unique products of power eigenvectors, related multipoles and singular values that provide two new rotationally invariant measures mode by mode. The power entropy and directional entropy are new tests of randomness that are independent of the usual CMB power. Simulated Galactic plane contamination is readily identified. The ILC– WMAP data maps show seven axes well aligned with one another and the direction Virgo. Parameter free statistics find 12 independent cases of extraordinary axial alignment, low power entropy, or both having 5 per cent probability or lower in an isotropic distribution. Isotropy of the ILC maps is ruled out to confidence levels of better than 99.9 per cent, whether or not coincidences with other puzzles coming from the Virgo axis are included. Our work shows that anisotropy is not confined to the low l region, but extends over a much larger l range.  相似文献   

Role of women as risk communicators to enhance disaster resilience of Bandung,Indonesia     

Mulyasari  Farah  Shaw  Rajib 《Natural Hazards》2013,69(3):2137-2160

This study addresses the need for women risk communication and highlights the potential role of Women Welfare Associations (WWAs) of Bandung, Indonesia, as risk communicators. A risk communication framework is modeled for women’s risk communication process. A set of indicators in social, institutional, and economic resilience activities (SIERAs), with a scope of 45 activities covering three different disaster periods, were developed to characterize the delivery process of risk information by women in WWAs through their activities at sub-district and ward levels. The data were collected through a questionnaire survey method using the risk communication SIERA approach. Women’s leaders at wards were surveyed concerning their perceptions on these 45 scopes of SIERA, ongoing activities, and their risk information source and dissemination process. Correlation analysis was applied to determine the relationship between the variables such as periods of disaster, types of activities (social, institutional, economic), and attributing factors (location, population, and education institution) in finding variations in risk communication activity that functions for women and communities. Five risk communication processes of WWAs are identified and implemented that work for women in Bandung. When their perceptions and ongoing activities are compared, activities such as dissemination of disaster risk information, conveying early warnings to their peers, and involvement of the local government have been confirmed to match the risk communication plans and implementation of WWAs. These indicate that WWAs’ activities in Bandung implement a certain degree of risk communication that is embedded in their activities. The results confirm that women through their social networks can become active agents of change and thus act beyond their usual domestic roles and responsibilities in order to contribute to the overall enhancement of community resilience.
