In this work, the controversy between the interpretations of recent measurements on dense aluminum plasma created with the Linac coherent light source (LCLS) x-ray free electron laser (FEL) and the Orion laser has been addressed. In both kinds of experiments, heliumlike and hydrogenlike spectral lines are used for plasma diagnostics. However, there exist no precise theoretical calculations for He-like ions within a dense plasma environment. The strong need for an accurate theoretical estimate for spectral properties of He-like ions in a strongly coupled plasma environment leads us to perform ab initio calculations in the framework of the Rayleigh-Ritz variation principle in Hylleraas coordinates where an ion-sphere potential is used. An approach to resolve the long-drawn problem of numerical instability for evaluating two-electron integrals with an extended basis inside a finite domain is presented here. The present values of electron densities corresponding to the disappearance of different spectral lines obtained within the framework of an ion-sphere potential show excellent agreement with Orion laser experiments in Al plasma and with recent theories. Moreover, this method is extended to predict the critical plasma densities at which the spectral lines of H-like and He-like carbon and argon ions disappear. Incidental degeneracy and level-crossing phenomena are being reported for two-electron ions embedded in strongly coupled plasma. Thermodynamic pressure experienced by the ions in their respective ground states inside the ion spheres is also reported. © 2015 American Physical Society.

The most significant part of prediction of precipitation is the detection and identification of convective (cumulonimbus) clouds, also the tracking of cloud movement is important for identification of location of precipitation. A very simple methodology for detecting convective clouds and then tracking its movement from a series of infrared (IR) images is proposed in this paper. IR image is segmented using k-means clustering algorithm, which has been implemented using Euclidean, Manhattan and Mahalanobis distances and the results have been compared. Cloud clusters have been identified from segmented image and subsequently the large clusters were extracted. Center of Mass (CoM) was calculated for each selected cloud cluster and its position after every 30 min was predicted and compared with the actual values. If the predicted position deviates, the proposed models automatically adjusts itself, and the next prediction becomes closer to original values of position. © 2012 Indian Society of Remote Sensing.

In the recent past, different kernelized versions of c-means (hard and fuzzy) clustering algorithms have been proposed. Here, we focus on kernel clustering of only object data, X = \{ {\bf x}1, \ldots,{\bf x}n \} \subset R^p. We first raise a basic question: Should we really cluster any given object data in the kernel space? The answer is NO! Here are our line of arguments: 1) The objective of any clustering algorithm is to find natural subgroups in X, where the subgroups are defined by a measure of similarity between the vectors in X. 2) If we transform the data X into Y in another space by a nonlinear transformation and try to find clusters in Y, then such clusters can be useful if and only if Y helps us to find the same clusters that are present in X because that is our objective. 3) If Y maintains the same structure/topology as that of X, then the use of Y may not give any advantage. 4) On the other hand, if Y changes the structure (i.e., imposes a new structure) on the data and that change makes the extraction of the desired clusters present in X easier, then clustering of Y is useful. 5) But when Y imposes new (nonexistent) structures, the clustering algorithm may find very strange clusters with no relation to the actual clusters present in X. 6) Thus, when we try to cluster in a transformed space, the issue is to know if it could help us to find the clusters present in X. To get any benefit from kernel clustering (or clustering in any other transformed space), we need to answer this question first; otherwise, we may find completely irrelevant clusters without knowing it and thereby making kernel clustering useless. 7) This issue is a philosophical one and is neither dependent on the choice of clustering algorithm nor on the particular transformation (kernel function) used. 8) Except for 2-D/3-D data, we do not know of any way to answer the question in 6) and for 2-D/3-D data, since we can look at the data, we do not need kernel clustering. Therefore, there is no benefit from kernel clustering. We demonstrate and justify our claims using both synthetic and real datasets with visual assessment as well as with normalized mutual information, adjusted Rand index, and cluster instability. We propose to use Sammon's nonlinear projection method to get a crude visual representation of the data in the kernel space. We discuss the issue of how to choose appropriate parameters of the kernel function, but we could not provide a solution to this problem. Finally, we discuss how the kernel parameters and the algorithmic parameters interact. © 1993-2012 IEEE.

We review the existing measures of uncertainty (entropy) for Atanassov's intuitionistic fuzzy sets (AIFSs). We demonstrate that the existing measures of uncertainty for AIFS cannot capture all facets of uncertainty associated with an AIFS. We point out and justify that there are at least two facets of uncertainty of an AIFS, one of which is related to fuzziness while the other is related to lack of knowledge or non-specificity. For each facet of uncertainty, we propose a separate set of axioms. Then for each of fuzziness and non-specificity we propose a generating family (class) of measures. Each family is illustrated with several examples. In this context we prove several interesting results about the measures of uncertainty. We prove some results that help us to construct new measures of uncertainty of both kinds. © 2012 Elsevier Inc. All rights reserved.

The astacins, a family of zinc-dependent endopeptidases have been widely detected in animal kingdom from humans to bacteria. They play a diverse role in both mature and developmental systems ranging from bone morphogenesis, tissue differentiation, hatching process, digestive function and in different diseases including cancer, inflammation, fibrosis and neurodegenerative diseases. In the absence of complete three-dimensional structure of the proteases, homology modelling has been carried to build at least the protease domain of this class of enzymes so that subsequent docking of substrates/inhibitors in future study will help to explore the differential substrate specificity of the astacins. © Springer India 2015.

Abstract: In the present work, a systematic basic research has been performed for finding out the effect of various process parameters viz. molar ratio of zinc sulfate and sodium hydroxide, reaction time and calcination temperature on size and morphology of ZnO nanoparticles synthesized using zinc sulfate as a precursor by sol–gel method. Taguchi design method, ANOVA and regression analysis were used to find out the effect of various process parameters on the response in terms of narrow particle size distribution and crystal size. Characterization was done to find out the response such as particle size distribution and crystal size by using TEM and XRD. Results revealed molar ratio of 1:2, and calcination temperature of 700 °C could significantly form uniform-sized spherical ZnO nanoparticles (85 nm) with narrow size distribution. However, significant increase in crystal size of ZnO nanoparticles was observed with increase in calcination temperature from 300 to 700 °C. This may be primarily due to governing of higher diffusion rate at high temperature which resulted in enhanced growth rate of ZnO crystals.
