Ad hoc networks are characterized by multi hop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols. This report compares the performance of MANET routing protocol such as Ad-hoc On Demand Distance Vector (AODV), LocationAided Routing (LAR1) and Wireless Routing Protocol (WRP) protocol at different(More)
Image segmentation has been an intriguing area for research and developing efficient algorithms, playing a paramount role in high caliber image interpretation and image analysis. Segmentation of images plays an imperative role in medical diagnosis. Such segmentation demands a robust segmentation algorithm against noise. The legendary orthodox fuzzy c-means(More)
The introduction of video sensors into a sensor network allows existing sensor network applications to be enhanced as well as providing for new applications which cannot be supported by typical scalar sensor networks. This is due to the vast amount of information which can be obtained from an image. Scalar data is insufficient for many applications such as(More)
The highly efficient direct α-alkylation of unactivated amides has been accomplished using alcohols in the presence of the Ru-PNN catalyst (0.1 mol%) with a high turnover number. Using this approach, 2-oxindole was directly transformed into C3-alkylated 3-hydroxyindolin-2-one in one step without the use of any oxidant.
IEEE defines various modulation schemes for WiMAX i.e. QPSK, BPSK, 16 QAM and 64 QAM. This model will examine Internet Protocol Television (IPTV) performance over Fixed WiMAX system taking many combinations of digital modulation. The performance will involve many key system parameters, which will involve the variation in the path loss, video coding,(More)
Total synthesis of (±)-taiwaniaquinol F (1a) has been accomplished via an efficient Lewis acid-catalyzed Nazarov-type cyclization of aryldiallylcarbinols (±)-2e derived from safranal 7. The methodology works under mild conditions using only 2 mol % of metal triflate as catalyst to afford a previously unknown carbotricyclic core sharing an olefin(More)
Idea of Smart farming pot is generated to automate the farming.Today, India ranks second worldwide in farm output. Agriculture and allied sectors like forestry and fisheries accounted for 13.7% of the GDP (Gross Domestic Product) in 2014, about 50% of the total workforce. The economic contribution of agriculture to India's GDP is steadily declining with the(More)
The study describes a simple and novel method for the synthesis of silver sulfide nanoparticles (Ag2S NPs). The synthesized NPs were characterized by SEM (scanning electron microscope), XRD (X-ray diffraction), particle size analyzer, zeta sizer and EDX (Energy dispersive X-ray). The Ag2S NPs were spherical in shape with an effective diameter size of 30 nm.(More)
