Study on integration of aluminum-doped zinc oxide (AZO) thin films with graphene oxide (GO)

Abstract: Aluminum (0.5 at.%)-doped ZnO (AZO) thin films were deposited by pulsed laser deposition technique (PLD) in oxygen ambient of 10−6 Torr. The deposited thin films were characterized by x-ray diffrac...

Space of Minimal n -Prime Ideals

Abstract: In this paper, we study the concept of an n-prime ideal in 0-distributive lattices. The characterization of minimal n-prime ideals is obtained. Further, the topology on the set $\mathcal {P}_{n}(L)$ of minimal n-prime ideals of a 0-distributive lattice L is studied and it is shown that $\mathcal {P}_{n}(L)$ is compact if and only if it is finite.

Monitoring Secchi disk transparency of Warasgaon reservoir of Pune by using LISS III sensor

Abstract: Secchi disk transparency (SDT) is the simplest and the most efficient measure to monitor water quality of the reservoir. The nutrients from the agriculture fields, sewage from human settlements and industries drain into reservoirs and lakes. It contributes to the increasing level of suspended particles, algal growth and coloring of water and reduces transparency of water. These changes can be detectable by remote sensors. In this study LISS III sensor of Resourcesat-2 used to model SDT of Warasgaon reservoir, Pune. The green (r = 0.75), red (r = 0.79) and NIR (r = 0.75) bands of LISS III showed good correlation with observed SDT, while band ratios Red/NIR (r = 0.81) and NIR/SWIR (r = 0.81) showed significant correlations. Several linear and multiple linear regression models developed from the in-situ measurements of SDT and the radiance value of LISS III image. The multiple linear regression model based on green, red, NIR and red/SWIR found to be the best fit (r = 0.88) to the in-situ data. The results showed that the Warasgaon reservoir was oligotrophic in condition during the December 2012.

Development of Low Cost Instrument for Measuring Suspended Solids in Fermented Wash

Abstract: An attempt has been made to develop a low cost system based on nephelometric principle for measurement of suspended particles in the effluent from Sugar factories and distilleries. The instrument uses a potential arrangement of two LDRs of 20mm in diameter, for compensating for inherent non-linearity of LDRs and providing a low-cost alternative. The paper describes mathematical model and the experimental results.

Connectivity and edge-bipancyclicity of Hamming shell

Abstract: A graph obtained by deleting a Hamming code of length $$n= 2^r - 1$$ from a n-cube $$Q_n$$ is called as a Hamming shell. It is well known that a Hamming shell is regular, vertex-transitive, edge-transitive and distance preserving (Borges and Dejter in J Comb Math Comb Comput 20:161–173, 1996; Dejter in Discrete Math 124:55–66, 1994; J Comb Des 5:301–309, 1997; Discrete Math 261:177–187, 2003). Moreover, it is Hamiltonian (Gregor and Skrekovski in Discrete Math Theor Comput Sci 11(1):187–200, 2009) and connected (Duckworth et al. in Appl Math Lett 14:801–804, 2001). In this paper, we prove that a Hamming shell is edge-bipancyclic and $$(n-1)$$ -connected.
