Push-to-Talk (PTT) is a useful capability for rapidly deployable wireless mesh networks used by first responders. PTT allows several users to speak with each other while using a single, half-duplex, communication channel, such that only one user speaks at a time while all other users listen. This paper presents the architecture and protocol of a fault tolerant PTT service for PTT in all IP Networks.

Polymers, the synthetic materials have truly unique properties.  The polymers are a very special kind of compounds, which do not behave like small molecules do, but the properties of polymers depend on molecular weight and molecular weight distribution (MMD). The molecular characterization of PANi base synthesized chemically by condensation method is attempted using MALDI-TOF MS technique.  Further the study is extended on doped PANi with two different strengths (0.01N, 1 N) of dopant HClO₄. The detailed descriptions of the method of TOF (Time of Flight) and the molecular weight determination of the PANi base and its doped form as conducting polymers have been studied quantitatively and strength of the dopant on the molecular characterization is also identified.

This paper presented a study of four algorithms, the equalization algorithm to equalize the transmission channel with ZF and MMSE criteria, application of channel Bran A, and adaptive filtering algorithms LMS, NMLS and RLS to estimate the parameters of the equalizer filter, i.e. move to the channel estimation and therefore reflect the temporal variations of the channel, and reduce the error in the transmitted signal. So far the performance of the algorithm equalizer with ZF and MMSE criteria both in the case without noise, a comparison of performance of the LMS, NLMS and RLS algorithm.

This research paper is based on extensive research work on success factors and framework of knowledge management in competency building of business organization. In this research paper the researcher analyzed the success factors, which are enablers towards decision making process and explore the knowledge management in every phases of the organizational decision making process. The researcher is also tried to optimize the decision making capabilities in competency building on decision making platform towards business optimization. This paper is also emphasized the success factors which directly affected to decision making capabilities in competency building of business organization.

The practice of interaction between parents and teachers is considered of utmost significance. No doubt, the present environment in the educational institutions of higher learning may not seem fit for such interaction. But if a small step is taken in this regard by involving the students and their parents through meetings of the parents and teachers, information to parents about the attendance of the students, information to parents about the performance of students, communication for disciplinary action against defaulters, feedback from the parents and suggestions of the parents, it will usher a new era in the qualitative aspects of an educational institutions of higher learning. The sample has been taken from 44 institutions of higher education in Haryana. 10 students from each institution were included in the sample. These 44 institutions include 19 urban aided institutions (13 co-ed. And 6 women colleges), 8 urban government institutions (5 co-ed. and 3 women colleges), 11 rural aided institutions (3 co-ed. and 8 women colleges) and 6 rural government institutions (3 co-ed. and 3 women colleges).

A coding scheme for OFDM transmission is proposed, exploiting a connection between pairs of Golay complementary sequences and second-order Reed-Muller codes. Using a realization of 16-QAM or 64 QAM constellation as the vector sum or two or three QPSK constellation respectively we construct 16 QAM and 64 QAM sequences having low PAPR. In this paper, we further examine the squared Euclidean distance of these M-QAM sequences and their variations. Our aim here is to combine the block coded modulation (BCM) and Golay complementary sequences to trade off the PAPR, the code rate, and the squared Euclidean distance of M-QAM OFDM signals
