Pertinent results with respect to embedded parameters are displayed through graphically for the velocity, Temperature, concentration, skin friction, Sherwood number, Nusselt number are discussed qualitatively

A Hybrid of Improved Bulls and Weighted Round Robin to optimize the Leader and Load Balancing in Cloud and Distributed Computing Environment

Day by Day there is increase of internet users which leads to increase the traffic in the network which causing the generation of huge data. It requires the balancing of network load on the network servers with different Load balancing techniques. It is also required to have efficient algorithm to analysis the huge data in distributed manner to identify the leader to act as centralized point of contact for services. If we audit on the heap adjusting systems, there are a few potential outcomes to upgrade the methods. In the present scenario, we have the methods, round robin algorithm (static load adjusting), Weighted Round Robin algorithm and Least Load algorithm (Dynamic Load Balancing). A researcher D. Chitra Devi .et .al has given the idea of enhanced weighted round robin algorithm (EWRR) which gives much better reaction when contrasted with basic round robin calculation. Another scholar Rashmi Saini et. al recommended the half breed of round robin calculation and minimum Load Algorithm. From the above scholars� articles, I hereby propose a resolution by improved Bulls algorithm along with Weighted Round Robin (WRR) algorithm to achieve high performance in Distributed and Cloud Computing domain in terms of leader election from a group of distributed and non-failed processes, load balancing dynamically and coordinate other nodes. Bulls algorithm uses the following message types: � Election Message: Sent to announce election. � Answer (Alive) Message: Responds to the Election message. � Coordinator (Victory) Message: Sent by winner of the election to announce victory. When coordinator fails to recover a process P, from failure or detecting before failure, the process P performs the following actions: 1. If P has the highest process id, it sends a Victory message to all other processes and becomes the new Coordinator. Otherwise, P broadcasts an Election message to all other processes with higher process IDs than itself. 2. If P does not receive any Election message, then it broadcasts a Victory message to all other processes and becomes the Coordinator. 3. If P receives an Answer from a process with a higher ID, it sends no further messages for this election and waits for a Victory message. When there is no Victory message after a stipulated period, it restarts the process from the beginning. 4. If P receives an Election message from another process with a lower ID it sends an Answer message back and starts the election process at the beginning, by sending an Election message to higher-numbered processes. 5. If P receives a Coordinator message, it treats the sender as the coordinator

A Review on Optimizing Radial Basis Function Neural Network using Nature Inspired Algorithm

Radial Basis Function (RBF) is a type of feed forward neural network .This function can be applied to interpolation, chaotic time-series modeling, control engineering, image restoration, data fusion etc. In RBF network, parameters of basis functions (such as width, the position and number of centers) in the nonlinear hidden layer have great influence on the performance of the network. Common RBF training algorithms cannot possibly find the global optima of nonlinear parameters in the hidden layer, and often have too many hidden units to reach certain approximation abilities, which will lead to too large a scale for the network and decline of generalization ability. Also, RBF neural network has the advantages of adaptive and self-learning ability, but it is difficult to determine the number of hidden layer neurons, and the weights learning ability from hidden layer to the output layer is low; these deficiencies easily lead to decreasing learning ability and recognition precision. Secondly, the Swarm Intelligence Algorithms are (Meta-Heuristic) development Algorithms, which attracted much attention and appeared its ability in the last ten years within many applications such as data mining, scheduling, improve the performance of artificial neural networks (ANN) and classification. So, in this paper the work of Artificial Bee Colony (ABC), Genetic algorithm(GA), Particle swarm optimization(PSO) and Bat algorithm(BA) have been reviewed, which optimized the RBF neural network in their own terms

Resource Management in Fog Networking of Cloud Computing using KNN Algorithm

It is necessary to deploy any application in Cloud environment to reduce the investment cost, maintenance cost and licence of hardware/software. Keeping these benefits, it is advised to go for cloud computing environment for any application deployment. The major challenge in this environment is fault tolerance of resources to support for continuous availability of resources to client for working. Especially in IoT applications, we use Fog networking connecting to cloud computing. In this scenario, it is advised to use KNN (K- Nearest Neighbour) resource identification and allocation algorithm to increase the throughput to user requirement. We are presenting an approach to allocate the required resources with optimal distance resource allocation, so as to improve the throughput of user requirement

A red alga Portieria hornemannii (Lyngb.) P. C. Silva 1987 (Gigartinales, Rhizophyllidaceae): A source of fragrance ingredient for perfume industry

898-902The application of marine plants such as seagrasses, seaweeds and mangroves for the production of perfumes are relatively less familiar to perfume industry. In the present study, a red seaweed Portieria hornemannii showing strong fragrance, collected from coral reefs of Gulf of Mannar, southeast coast of Tamil Nadu, India is proposed as a potential source of fragrance for perfumes. This species has a distinctive essence of perfume like flowery scents and can give off pleasant fragrance immediately after rubbing or rupture. Gas Chromatography and Mass Spectrometry analysis of methanol extracts of P. Hornemannii revealed the presence of chemical components N'-(3-Phenyl-2-Propenylidene)-2-(4-Chlorophenoxy) acethydrazide and 4, 5-Dichlorotricyclo [4.4.0.0(2,8)] dec-3-ene

Mass mortality of regular sea urchin Salmacis virgulata L. Agassiz and Desor, 1846 at Dhanushkodi, Southeast coast of Tamil Nadu, Gulf of Mannar, India

Mass mortality of sea urchin, Salmacis virgulata scattered over the periphery of Dhanushkodi beach, was observed on February 13, 2019. More than 100 numbers of recently dead and dying specimens were found within a 10 m2 area on the sandy beach. Beach profiles indicated several hundreds of exoskeletons of previously dead S. virgulata were washed ashore and buried in sand and withering seagrass. The causative agent responsible for mass mortality of S. virgulata is yet to be discovered. However, observations on wave approach toward shore indicated possible evidence that it could be due to a combination of strong nearshore waves and currents. This observation raises a critical research concern to investigate etiology of S. virgulata for species conservation
