This paper presents a flower classification and identification system that takes a flower image as input and identifies it to be belonging to a particular category present in the database. It begins by performing pre-processing operations on the input image. A set of digital images are segmented using k-means clustering algorithm from which texture and color features are extracted. Texture feat...

In this paper we discuss a new model for document clustering which has been adapted using non-negative matrix factorization method. The key idea is to cluster the documents after measuring the proximity of the documents with the extracted features. The extracted features are considered as the final cluster labels and clustering is done using cosine similarity which is equivalent to k-means with...

We present the results for the measurement of φ meson production in √ s N N = 200 GeV Au+Au and pp collisions at the Relativistic Heavy Ion Collider (RHIC). Using the event mixing technique, spectra and yields are obtained from the φ → K + K − decay channel for different centrality bins in Au+Au collisions and in pp collisions. We observe that the spectrum shape in Au+Au collisions depends weak...

Proposed system has been developed to extract the optimal features from the breast tumors using Enhanced Cuckoo Search (ECS) and presented in this paper. The texture feature, intensity histogram feature, radial distance feature and shape features have been extracted and the optimal feature set has been obtained using ECS. The overall accuracy of a minimum distance classifier and k-Nearest Neigh...

Several DNA extraction techniques were quantitatively and qualitatively compared using both fresh and paraffin wax embedded tissue and their suitability investigated for providing DNA and RNA for the polymerase chain reaction (PCR). A one hour incubation with proteinase K was the most efficient DNA extraction procedure for fresh tissue. For paraffin wax embedded tissue a five day incubation wit...

The under-sample classification problem is discussed for 21 normal childrenand 21 children with reading disability. We first rejected data of one subject in each group and produced 441 sub-datasets including 40 subjects in each. Regarding each sub-dataset, we extracted features through nonnegative Tucker decomposition (NTD) from event-related potentials, and used the leaveone-out paradigm for c...

We present measurements of the transverse momentum spectra for K 0 S , Λ, Ξ and their antiparticles in p+p collisions at √ s = 200GeV. The extracted mid-rapidity yields and p T are in agreement with previous p + ¯ p experiments while they have smaller statistical errors. We compare the measured spectra for K 0 S and Λ to the latest available calculations from NLO pQCD and see good agreement for...
