— Rao-Blackwellized Particle Filter and FastSLAM have become popular tools to solve the Simultaneous Local-ization and Mapping (SLAM) problem. However, the above techniques have two important potential limitations, which are the derivation of the Jacobian matrices and the linear approximations to the nonlinear functions. Also, one of the major challenges of(More)
BACKGROUND Therapeutic potential was evaluated in a rat model of myocardial infarction using nanofiber-expanded human cord blood derived hematopoietic stem cells (CD133+/CD34+) genetically modified with VEGF plus PDGF genes (VIP). METHODS AND FINDINGS Myocardial function was monitored every two weeks up to six weeks after therapy. Echocardiography(More)
This paper proposes and implements an energy efficient, high speed pipelined Multiply and Accumulate (MAC) architecture for DSP applications. A controller has been designed to detect the input pattern such that it bypasses multiplier and accumulator units depending on the consecutive input bits. This architecture is used for both signed and unsigned(More)
In this paper, an H-bridge inverter topology with reduced switch count technique is introduced. This technique reduces the number of controlled switches used in conventional multilevel inverter. To establish a single phase system, the proposed multilevel inverter requires one H-bridge and a multi conversion cell. A multi conversion cell consists of three(More)
The present study focuses on the role of remote sensing and geographic information system (GIS) in assessment of changes in forest cover, between 1931 and 2001, in the Kalrayan hills, Tamil Nadu. The trend of forest cover changes over the time span of 70 years, was precisely analysed using high resolution Satellite data. The study revealed that the forest(More)
Antagonizing TNF-α signaling attenuates chronic inflammatory disease, but is associated with adverse effects on the cardiovascular system. Therefore the impact of TNF-α on basal control of redox signaling events needs to be understand in more depth. This is particularly important for the Keap1/Nrf2 pathway in the heart and in the present study we(More)
