Gaussian approximation using integer sequences
(2014) Rajan, A.; Rao, A.; Vittal, Rao, R.; Jamadagni, H.S.
The need for generating samples that approximate statistical distributions within reasonable error limits and with less computational cost, necessitates the search for alternatives. In this work, we focus on the approximation of Gaussian distribution using the convolution of integer sequences. The results show that we can approximate Gaussian profile within 1% error. Though Bessel function based discrete kernels have been proposed earlier, they involve computations on real numbers and hence increasing the computational complexity. However, the integer sequence based Gaussian approximation, discussed in this paper, offer a low cost alternative to the one using Bessel functions. � Springer International Publishing Switzerland 2014.

Near field communication - Applications and performance studies
(2012) Akshay, Uttama, Nambi, S.N.; Prabhakar, T.V.; Jamadagni, H.S.; Ganapathi, K.; Pramod, B.K.; Rakesh, C.M.; Sanjay, Naik, R.
Near Field Communication (NFC), is an integration of Radio Frequency Identification (RFID) technology with mobile devices. NFC offers a quick and convenient method of interaction between humans and NFC enabled devices. Current research concerning NFC appears to mainly focus on development of NFC enabled applications and services. In this paper, we study the performance of NFC devices by considering metrics such as achieved data rates and received power for several distances. Knowledge of these metrics may be useful for application developers to build applications efficiently. We have developed various applications on NFC enabled devices for public transport systems. We also describe the design of 13.56 MHz antenna which was used for measurements of the received power. � 2012 Springer-Verlag.
