The study involves segmentation of the image using the three segmentation modules of three software namely ERDAS Imagine, ENVI and eCognition to extract building features. The best parameters for segmenting buildings have been established. New method of evaluation has been presented for evaluating segmentation quality. The results of three segmentation… (More)
The recognition of spatial patterns of trees from satellite images is important for forestry, horticulture, and wildlife management. As a spatial optimization problem, we used variogram matching as the objective function for simulated tree arrangements and their simulated reproductions. We developed a variogram difference-based spatial simulated annealing… (More)
A series of new acylamide derivatives with piperidine, pyrrolidinyl and alanyl have been tested for their hypoglycemic activities. 2-(Pyrrolidynyl)-N-(3-chlorophenyl) acetamide and 2-(Piperazinyl)-N-(4-methoxy phenyl) acetamide were found most active hypoglycemic compounds. Probably the amides have mode of action similar to sulphonylureas.
Complete 1H and 13C spectral assignments are reported for six saponins from the pericarp of Sapindus trifoliatus (Hindi name: Reetha) collected from Madhya Pradesh and Maharashtra, India, using only 1D and 2D NMR methods. The structures of the compounds were elucidated as hederagenin… (More)
A series of S-arylformamidino-N-(alkyl/arylisothiourea) Cyclicamino dihydrochlorides were synthesised and screened for their hypoglycemic activity in normal as well as alloxanized diabetic rats. Some of the compounds (Id, Ie, Ih-1) showed more than 30% lowering of blood sugar level of Albino rats.
