High-speed router design for network on chip(HSRDn) is proposed for controlling the traffic congestion and deadlocks. Diagonal based nearest-path routing algorithm for no C(DnRAn) can mitigate the effect of latency by opting for the nearest-path to reach the destination in a network and HSRDn is part of DnRAn. When we analyze the performance of DnRAn for all proposed topologies, nearly 50% better in terms of latency reduction and high throughput over existing router architectures. The proposed topologies(2 D-mesh,2 D-Star mesh over regional mesh(SMo RM), 3 D-mesh,and 3 D-torus) are tested with various applications, viz,audio, video and so on. Here, we also tested with cryptography application for DnRAn. When we analyzed the performance of experimental results, exclusively in 2 D-SMo RM nearly 0.6 times latency get reduced, area expanded by 0.25 and 0.33 times throughput increase in 2 D-SMo RM compared with 3 D-mesh and 3 ***, DnRAn showed an exclusive performance in 2 D-SMo RM compared with other two topologies.

Majority of shallow floodplain lake ecosystems of the middle and lower reaches of the Yangtze River(China) have gone through serious eutrophication problems over the recent past. The severe environmental deterioration accompanied by cyanobacterial blooms have become major water resource management challenges in the region. An advanced research method is urgently needed to tackle these challenges. The concept of ecological resilience address pressing questions of non-linear dynamics, threshold effects and regime shifts in shallow floodplain lakes, and help manage the ecosystem effectively. Palaeolimnological techniques are important for assessing long term resilience and associated thresholds effects of shallow lake ecosystems. However, the lack of reliable proxy methods available, the assessment of long term ecological resilience of shallow Yangtze River lake systems has become increasingly difficult. Cladocerans(water fleas) play a central role in lacustrine food webs by responding to external drivers and internal ecosystem processes in lakes. Their subfossils are well preserved and becoming one of potential proxy indicators of lake ecosystems change for a longer time scale. This study explores the potential application of subfossil cladocerans and their ephippia in assessing a long term ecological resilience and help better management strategies of lake ecosystems and water resources of the middle and lower reaches of the Yangtze River in China.

In this study,we derive the sharp bounds of certain Toeplitz determinants whose entries are the coefficients of holomorphic functions belonging to a class defined on the unit disk ***,these results are extended to a class of holomorphic functions on the unit ball in a complex Banach space and on the unit polydisc in C^(n).The obtained results provide the bounds of Toeplitz determinants in higher dimensions for various subclasses of normalized univalent functions.

Identification and monitoring of species composition and richness isneeded to formulate effective mangrove management and conservationpriorities. Prior studies have used commercial satellite images which arecost prohibitive for national and global applications. Here, we usedfreely available Landsat satellite data and new indices to discriminatemangrove species in Maros Regency, South Sulawesi, Indonesia andSegara Anakan, West Java, Indonesia. We use sensitive algorithm of theprincipal polar spectral (PPS) indices to discriminate mangroves *** Indices were produced from a set of 3-dimensional Landsat 8Operational Land Imager (OLI) spectral indices (PPS Brightness, PPSGreenness, and PPS Wetness) determined by a polar change of theprincipal component axes of a spectral image of reference scene. Wequalitatively compare this set of PPS indices with the set of conventionalRGB multi-bands image composition and conventional normalizedDifference Vegetation Indices (nDVI) for mangroves speciesdiscrimination. The comparisons indicate that the set of PPS indiceshave the potential for regional and possibly global applications inmangroves species mapping and monitoring.

More efficient oxidation methods are needed to degrade especially newly emerging recalcitrant organic contaminants at low concentrations in the water environment. Reduced photonic efficiency of immobilized TiO2 is a major challenge in TiO2-assisted advanced oxidation processes (AOP). Mineralization of 2,4-dichllorophenoxyacetic acid (2,4-D) in low aqueous solution by O3/UV/TiO2 using the world’s first high-strength TiO2 fiber was investigated and compared with O3, UV/TiO2, and O3/TiO2 in laboratory batch ex...
