The growing availability of information technologies has enabled law enforcement agencies to collect detailed data about various crimes. Classification is the procedure of finding a model (or function) that depicts and distinguishes data classes or notions, with the end goal of having the ability to utilize the model to predict the crime labels. In this research classification is applied to crime dataset to predict the "crime category" for diverse states of the United States of America (USA). The crime data set utilized within this research is real in nature, it was gathered from socio-economic data from 1990 US census. Law enforcement data from 1990 US LEMAS survey, and from the 1995 FBI UCR. This paper compares two different classification algorithms namely -Naïve Bayesian and Back Propagation (BP) for predicting "Crime Category" for distinctive states in USA. The result from the analysis demonstrated that Naïve Bayesian calculation out performed BP calculation and attained the accuracy of 90.2207% for group 1 and 94.0822% for group 2. This clearly indicates that Naïve Bayesian calculation is supportive for prediction in diverse states in USA.

Partial Discharge (PD) detection plays a vital role in electrical power stations, it can help protecting the high voltage equipment, it can prevent explosion of these equipment and hence preventing a catastrophic failure. PD detection can be performed in two modes, i.e. frequency domain and time domain. The characteristics of PD signal varies due to size and type of equipment it arises from. Wireless emerging technologies such as Software Defined Radio (SDR) can be used for PD detection. In this paper two PD source were employed to generate PD signals, a floating-electrode PD emulator was used and PD signals were detected using SDR system, and, a floatingelectrode PD emulator is replaced by a HVPD pC calibrator, while the detection system is kept the same. A comparison shows that afloating-electrode PD emulator generates stronger PD signals than HVPD pC calibrator. Furthermore, although a HVPD pC calibrator is commercial and more sophisticated and expensive than floating-electrode PD emulator, a floatingelectrode PD emulator generates stronger signals and overall better results.
