In this paper we have proposed a system that will be able to analyze the Optimum Crop Cultivation of Bangladesh based on the knowledge of Neuro-Fuzzy System (NFS). The Neuro-fuzzy system is the collection of two techniques: fuzzy logic and the neural network. The system can compute the yield of a certain crop by using the value of humidity, temperature and… (More)
Data Mining is the process of finding pattern or useful information from large volume of data. The goal of this paper is to find the reason behind the unusual high birth rate by applying data mining techniques, e.g., decision tree, neural network, Bayes Classifier, Ripper and Support Vector Machine. The datasets were collected from the baseline survey… (More)
The mass spectra of grayanotoxin III and some of its mono-, di, and tri-ester derivatives are discussed. Some of the physiological responses of this compound class are also presented. The extraction of this material from a natural source is discussed as well as the schemes for ester derivatization and spectral characterization of all compounds studied. High… (More)
Different new esters of 5-aryl-1,3,4-thiadiazol-2-ylcarbazic acid and dithiocarbazic acid were prepared. In addition, the synthesis of 2-(N,N'-dialkylcarboxy)hydrazino-5-aryl-1,3,4-thiadiazoles is described. IR and NMR data of the new compounds are discussed. Some of these compounds showed a reasonable activity against Gram positive bacteria and fungi.
