An interannual study on zooplankton abundance, biomass, and species composition was carried out during different seasons in two local coastal water types off Gopalpur, north-western Bay of Bengal. Although, Type-1 was observed with higher zooplankton abundance in comparison to Type-2, pattern of variation followed similar seasonal trends in both water types during individual years. Well pronounced seasonality was observed in zooplankton distribution. Zooplankton community was composed of 217 holoplankton and 22 meroplankton. The holoplankton community was predominated by copepod in terms of species diversity and abundance followed by hydrozoa, tintinnida, malacostraca, gastropoda, chaetognatha and chordata. The meroplankton were represented by larval forms viz. bivalve veliger, brachyuran zoea larvae, caridean larvae, copepod nauplii, fish egg and gastropod veliger. Dominance of copepod species viz. Acrocalanus longicornis, Paracalanus aculeatus and Paracalanus parvus were observed frequently in both water types. The species richness was higher in Type-1 in comparison to Type-2 during both the years. Salinity regimes and availability of phytoplankton prey influenced the distribution and species composition of zooplankton assemblage.

This paper presents a new approach to singular system analysis by modeling the system in terms of orthog- onal triangular functions （TFs）. The proposed method is more accurate compared to block pulse function-based analysis with respect to mean integral square error （MISE）. A numerical example involving four states of a singular system is treated and solutions obtained thereof. Four tables and relevant curves are presented to compare the respective coefficients in block pulse function （BPF） domain as well as in TF domain. The percentage error of the samples determined via TF domain are compared with the exact samples of the states. Furthermore, MISE for both BPF and TF analysis are computed and compared to reveal the efficiency of TF-based analysis.

This paper presents a new recursive method for system analysis via double-term triangular functions （DTTF） in state space environment. The proposed method uses orthogonal triangular function sets and proves to be more accurate as compared to single term Walsh series （STWS） method with respect to mean integral square error （MISE）. This has been established theoretically and comparison of error with respect to MISE is presented for clarity. A numerical example is treated to establish the proposed method. Relevant curves for the solutions of states of the dynamic system are also presented with plots of percentage error for DTTF-based analysis.

Classification methods play an important role in investigating crime in forensic research. Here we assess the relative performance of several classification methods, such as Logistic Regression （LR）, Linear Discriminant Analysis （LDA）, Quadratic Discriminant Analysis （QDA）, Mixture Discriminant Analysis （MDA） and Classification Tree （CT） on glass identification data. We present a different approach to investigate the relative performance of the classifiers by invoking the tests of statistical significance and the receiver operating characteristic （ROC） curves in addition to estimating the probabilities of correct classification （PCC）. The area under the receiver operating characteristic curve （AUC）, the error rate and its 95% confidence interval are used to measure predictive power of these algorithms. Dimensionality reduction of data has been conducted using principal component analysis （PCA） and Fisher＇s linear discriminant analysis （FDA） and two major components were identified. Among all the classification methods mentioned above, the LDA and the QDA are observed to be statistically significant. The Box＇s M test （P〈0.0001）, which is used to test the homogeneity of covariance matrices, showed that the homogeneity of covariance could not be assumed for LDA. This suggests that for glass types, window and non-window, the QDA is superior to all methods. The CT, however, has been found to outperform FDA when all six categories of glass are considered.
