An expert system having two stages is proposed for cardiac arrhythmia diagnosis. In the first stage, Fisher score is used for feature selection to reduce the feature space dimension of a data set. The second stage is classification stage in which least squares support vector machines classifier is performed by using the feature subset selected in the first stage to diagnose cardiac arrhythmia. ...

a wide range of medicinal plant parts that possess varied medicinal properties are used for extracts as raw drugs. in this study, the ethanolic extract obtained from aerial parts of fennel (foeniculum vulgare mill.) seedlings was evaluated in vitro to examine their antimicrobial activity against four gram-negative and three gram-positive bacteria and two fungi. aerial parts of one-month-old see...

---Medical Image Analysis is essential in order to detect and diagnose the various types of Cancers. In recent years there is a rise in the death rate of patients suffering from brain cancer and lung cancer. The chances of survival among people can increase if the detection is done in the earlier stage. The widely used diagnose technique is Magnetic Resonance Imaging (MRI), Computed Tomography ...

We analyze a two stage sequential probit model that can be used to analyze survey in which questions are asked sequentially and unobservable variables of each stage can be correlated. We apply the model to innovation surveys. In the first stage, the survey asks if firms have developed a product or a process innovation. In the second stage, the survey inquires about the degree of novelty o the i...

genitourinary tuberculosis (gutb) is difficult to diagnose in the earlier stage owing to the non-specific symptoms. usually, renal tuberculous involvement is unilateral and the imaging finding is renal calcification, but associated calcifications of bilateral ureter and bladder are rare. we report a 66-year-old man who presented with diffuse calcification of the urinary system (including bilate...
