Medical professionals need a reliable prediction methodology to diagnose cancer and distinguish between the different stages in cancer. Classification is a data mining function that assigns items in a collection to target groups or classes. C4.5 classification algorithm has been applied to SEER breast cancer dataset to classify patients into either(More)
Orthogonal Frequency Division Multiplexing (OFDM) is the digital multicarrier modulation scheme for high speed communication systems. One of the major problems in OFDM is the occurrence of high Peak to Average Power Ratio (PAPR). Due to high PAPR the signal leads to out-of-band (OBO) distortion and increase in Bit Error Rate (BER). The reduction in PAPR is(More)
Cloud Computing delivers computing resources as a service over a network (Internet) to the customers. The tasks or jobs of the users would require to be executed in a particular order to complete the whole task. Workflow scheduling manages the execution of the inter-dependent tasks on the distributed resources. Workflow scheduling algorithms are used to(More)
Object recognition is one of the key areas in computer vision which comprises of object detection, recognition and reconstruction. The image of the object to be recognized is captured using camera and matched with pre-stored templates of the model object. Recognizing 3D view of the object is difficult in the presence of object occlusion and view-point(More)
We investigate the high peak power resulting from the transmission of orthogonal frequency division multiplexing (OFDM) signals through optical fiber. High peak-to-average power ratio (PAPR) which is a major drawback of OFDM can make worse the nonlinearities experienced in optical fibers. Phase modulation instead of intensity modulation is adopted to keep(More)
