Reactive power management in a power distribution network of a power utility and industry plays a major role in reducing distribution loss, in maintaining constant distribution voltage and in improving power factor. The paper presents the simulation studies on a cascaded H-Bridge converter based DSTATCOM for power factor improvement in power distribution(More)
Digital data communication uses various modes of encoding the data bits into a frequency signal. Phase shift keying (PSK) of various forms such as Binary PSK, Quaternary PSK etc., are in vogue in several current communication schemes such as GSM. In this paper, a different scheme of encoding digital data using wavelet functions instead of sinusoidal waves(More)
We present a simple observation for neutrino mixings and masses which arises naturally in dimensional deconstruction models. There are two essential ingredients of such models: (i) the presence of a symmetry mediated by the link fields which results in the neutrino mixings to be maximal; and (ii) a deconstruction scale which for large values gives rise to a(More)
We assume that the mass matrix of active neutrinos has hierarchical form with small mixings, similar to quark mass matrix. We show that the large mixings between νμ and ντ as well as between νe and certain combination of νμ and ντ required by the present data can appear due to the presence of a sterile neutrino state. Two realizations of this possibility(More)
We study breakdown of CPT symmetry which can occur in the decay process BB̄ → lXf with f being a CP eigenstate. In this process, the standard model expectations for time ordered semi-leptonic and hadronic events, i.e. which of the two decays takes place first, can be altered in the case that there is a violation of the CPT symmetry. To illustrate this(More)
