Geospatial Depiction of Groundwater Level Disparities on a Temporal Component over Portions of Cuddapah District, India Using Contemporary Geo Tools and Interrelated Statistics
Abstract: This paper mainly focuses on comparing methods such as Deterministic methods, Geostatistical methods and Interpolation methods in order to obtain a good fit to represent groundwater level disparities existed in the study area from 1996 to 2015. Inverse Distance Weighting, Global Polynomial Interpolation, Radial Basis Functions, Local Polynomial Interpolation, Kriging, Empirical Bayesian Kriging, Kernel smoothing and Diffusion Kernel were the methods tested for the present study. The data set procured …

Phase Noise Reduction in WLAN by Applying Wavelet Packet Multiplexing
Abstract: The IEEE 802.11 standards for wireless Local Area Networks (LANs) commercialized as Wi-Fi are deployed in office and home environments. These systems provide data rates up to 1300 Mbps at 5 GHz and 400 Mbps at 2.4 GHz with physical layer based on OFDM and MIMOOFDM. Traditionally, multiplexing in OFDM is realized using static orthogonal waveforms derived from Fourier transforms. The decoding of the data at receiver is based on …

Heavy Metal Assessment of Rainwater from Owerri Metropolis and Suburbs of Imo State, Nigeria Using GIS, MATLAB and ANN Models.
Abstract: Three hundred and fifty (350) rainwater samples were collected from 35 select locations within Owerri Metropolis, Ehime Mbano and Mbaitoli LGAs and analyzed for Cd, Cu, Fe, Zn, and Pb using standard instrumental methods. The results were compared with the World Health Organization (WHO), National Ambient Air Quality Standards (NAAQS), Federal Environmental Protection Agency (FEPA) and National Agency for Food and Drug Administration and Control (NAFDAC) Standards for drinking water …

Geo-chemical Analysis of Arsenic in Medium Aquifers and Its Relation with Physical Parameters: A Study of Ballia District, India
Abstract: The main objective of this paper is to assess the spatial variation of arsenic (As) in medium aquifer and to relate it with surface elevation and slope generated using Shuttle Radar Topography Mission (SRTM) satellite data and water table. Water samples were collected in both pre- and post-monsoon season in 2011. The analysis of water samples for As were carried out by using atomic absorption spectrophotometer (AAS). Total 33 water …

Performance comparison of DWT OFDM systems and FFT OFDM system over an AWGN channel
Abstract: Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital data on multiple carrier frequencies. The OFDM systems till now have been used as what we can call as a conventional OFDM incorporates Inverse Fast Fourier Transform (IFFT) blocks in their transmitters and FFT (FFT) blocks in their receivers. Recent research shows that the use of Inverse Discrete Wavelet Transform (IDWT) in place of IFFT and Discrete Wavelet Transform (DWT) …
