A FRAMEWORK FOR QUERY RECOMMENDATION ON LOCATION-BASED QUERIES
Existing keyword insinuation techniques don't ponder about the locations from the users and also the query ensue i.e., the spatial oppressiveness of the user towards the retrieved results isn't taken preference a water in the recommendations. We advise a weighted keyword-document chart, which captures both semantic applicability between keyword queries and also the spatial distance between your resulting dogma and also the user place. We design the very first ever Location-aware Keyword Query Suggestion framework, for suggestions highly relevant to the user’s message needs which recover germane dogma well-nigh to the query issuer’s location. Our prompt LKS framework is orthogonal to and could be conveniently integrated out of all complaint techniques that make use of the query-URL bipartite chart. That LKS hold a different goal and for that reason is distinct from other location-sensitive recommendation methods. The very first blame in our LKS framework is how you can thoroughly measure keyword query similarity while recording the spatial restraint factor. To insure this affirmation, we conducted experience second-hand two denser versions in our datasets the close America online-D. Particularly, the outcross method outperforms other approaches since it uses both spatial and textual constituent throughout the ink propagation process, and therefore soothsay better the moving the ink may have a tendency to proceed and cluster, achieving better partitioning. Set up a baseline formula amplify from formula BCA is brought to solve the issue. Then, we allude to a partition-supported formula which figure the lots of the candidate keyword question in the partition straightforward and found on an inert clockwork to succour reduce the computational cost
IDENTIFYING FOR NODE COLLAPSE IN MWN’S USING A PROBABILISTIC APPROACH
Extensive resemblance leads to both related and disordered systems show our purpose achieves tall failure acknowledgment rates and occasional dishonest positive ratio and acquire low news overhead. The ready appropinquate can proceed in a lot of meshwork-distant traffic, incompatible using the restricted fountain in excitable wireless systems. Our approach has got the advantage that it's relevant to both connected and abrupt systems. When simile with other approaches which use localized monitoring, our approach has similar failure notice cost, fall conference overhead and far lower perfidious positive cost. Additionally, an ear has got the advantage that it's relieving to both united and off systems while centralized monitoring is true germane to connected systems. Within an intramural feeling where Gps navigation doesn't work, a node may utility intramural localization techniques. Different location devices and methods have different amounts of error in placing measurements. The failure probability depends upon the node itself along with the atmosphere. Our access only generates localized monitoring bargain and it is relevant to both adjunct and desultory systems many localization techniques occur to be coded in the learning. In the finish, we make a superior enclose of non-performance recognition rate using our advances
Orange Photoluminescence from Hydrothermally Grown Zno Nanorods and Study on its Defects
The visible photoluminescence (PL) of ZnO is controversial for a long time. At present, the contribution of oxygen interstitial defects to yellow/orange emission from ZnO nanostructures is on debate. In this report, the origin of orange emission from solution- grown ZnO nanorods is investigated using excitation wavelength dependent photoluminescence PL, PL excitation and UV-Vis spectra. These results showed that orange emission may be due to the transition of an electron from shallow defect levels positioned slightly below the conduction band to the singly ionized oxygen vacancies. Hence, it is believed that oxygen interstitials may not be responsible for orange emission from solution grown ZnO nanostructures
Evaluation of groundwater quality and its suitability for drinking and agricultural use in Thanjavur city, Tamil Nadu, India
As groundwater is a vital source of water for domestic and agricultural activities in Thanjavur city due to lack of surface water resources, groundwater quality and its suitability for drinking and agricultural usage were evaluated. In this study, 102 groundwater samples were collected from dug wells and bore wells during March 2008 and analyzed for pH, electrical conductivity, temperature, major ions, and nitrate. Results suggest that, in 90% of groundwater samples, sodium and chloride are predominant cation and anion, respectively, and NaCl and CaMgCl are major water types in the study area. The groundwater quality in the study site is impaired by surface contamination sources, mineral dissolution, ion exchange, and evaporation. Nitrate, chloride, and sulfate concentrations strongly express the impact of surface contamination sources such as agricultural and domestic activities, on groundwater quality, and 13% of samples have elevated nitrate content (>45 mg/l as NO3). PHREEQC code and Gibbs plots were employed to evaluate the contribution of mineral dissolution and suggest that mineral dissolution, especially carbonate minerals, regulates water chemistry.Groundwater suitability for drinking usage was evaluated by the World Health Organization and Indian standards and suggests that 34% of samples are not suitable for drinking. Integrated groundwater suitability map for drinking purposes was created using drinking water standards based on a concept that if the groundwater sample exceeds any one of the standards, it is not suitable for drinking. This map illustrates that wells in zones 1, 2, 3, and 4 are not fit for drinking purpose. Likewise, irrigational suitability of groundwater in the study region was evaluated, and results suggest that 20% samples are not fit for irrigation. Groundwater suitability map for irrigation was also produced based on salinity and sodium hazards and denotes that wells mostly situated in zones 2 and 3 are not suitable for irrigation. Both integrated suitability maps for drinking and irrigation usage provide overall scenario about the groundwater quality in the study area. Finally, the study concluded that groundwater quality is impaired by man-made activities, and proper management plan is necessary to protect valuable groundwater resources inThanjavur city

Genetic Variability and Divergence of Morphological and Seed Quality Traits of Greengram (Vigna radiata L.) Genotypes
Forty greengram genotypes were evaluated for their morphological traits and to find the extent of genetic variability. Analysis of variance revealed that the genotypes were highly significant for all the characters studied, indicating the existence of considerable magnitude of variability. High (>20%) phenotypic co-efficient of variation and high genotypic co-efficient of variation for seed yield (kg/4.05 m2) in the present investigation was noticed and indicating the minimal influence of environment and presence of high genetic variability for the trait in the experimental material. Hence, selection based on phenotype in these genotypes can also be effective for improvement of seed yield. High heritability to plant height (cm), days to 50% flowering, days to maturity, pod length, 100 seed weight, protein estimation and medium heritability to seed yield (kg/4.05 m2). High GAM to plant height and seed yield demonstrates the presence of additive gene effect indicating effectiveness of selection for improvement of these traits. Mahalanobis D2 analysis suggested the maximum contribution of seed yield (74.87%) towards genetic diversity followed by Plant height (8.08%), Days to Maturity (7.69%), Pod length (4.36%), Days to 50% flowering (3.59%), Seedling Dry Weight (0.64%), Protein Estimation (0.64%), 100 seed weight (0.13%). All 40 genotypes were grouped into 12 clusters. The clustering pattern revealed that genetic diversity was associated with geographical diversity in the present research. Based on mean performances, the genotypes PUSA-9072, MLGG-21-2, IC-436557, MLGG-21-6, RMP-21-11, Gouri, MLGG-21-3, MGG-512, MGG-519 from these clusters can be directly used as parents in the hybridization programme. The output of this study is characterization of greengram genotypes for DUS characters and other traits. This study helps in identification of genotypes with suitable traits, helps in registration of lines with PPV and FRA and the material can be used in breeding programmes
Characteristics of indium tin oxide films deposited by bias magnetron sputtering
Indium tin oxide coatings have been deposited on glass substrates with substrate bias as a process parameter along with substrate temperature. It was found that films deposited with substrate heating and/or substrate bias were polycrystalline in nature and predominantly (400) oriented. The results are correlated to microstructural variation due to the process parameters. Films with lowest sheet resistance, 7.6 ohm/sq and electron concentration of have been achieved in case of films deposited at with a substrate bias of + 18
