Online searching is one of the most frequently performed actions and search engines need to provide relevant results, while maintaining scalability. In this paper we introduce a novel approach grounded in Cohesion Network Analysis in the form of a semantic search engine incorporated in our Hub-Tech platform. Our aim is to help researchers and people unfamiliar with a domain find meaningful articles online, relevant for their project scope. In addition, we integrate state-of-the-art technologies to ensure scalability and low response time, namely SOLR - for data storage and full-text search functionalities - and Akka - for parallel and distributed processing. Preliminary validations denote promising search results, the software being capable to suggest articles in approximately the same way as humans consider them most appropriate - 75% are close results and top 20% are identical to user recommendations. Moreover, Hub-Tech recommended more suitable articles than Google Scholar for our specific task of searching for articles related to a detailed description given as input query (50 + words).

the usage of emerging wireless technologies increases the demand for energy and data transfer. the recent development in wireless sensor networks (WSNs) and enactment withthe intelligent sensor in many applications, especially electronic instrumentation needs a sufficient amount of power for node devices. thus, energy harvesting (Ell) is resourceful from surrounding electromagnetic sources that transmit energy freely. this paper discusses energy efficiency (EE) trade-offs and EE maximization for wireless power and information transfer for WSNs. Furthermore, the power splitting (PS) scheme investigated and EE maximization analyzed for simultaneous wireless information and power transfer (SWIPT). this work formulates an optimization problem to maximize EE. this paper deals with an objective function as a non-convex optimization problem and proposed solution by optimal PS ratios. the proposed algorithm obtains the optimal solution using non-linear fractional programming and Lagrangian dual decomposition method. Simulation results confirm that the proposed algorithm attains optimal energy transfer ratio through noteworthy improvements.

Linear Feedback shift Registers (LFSRs) are widely used in encoders like Cyclic Redundancy Check (CRC) for generating error detecting codes. In order to achieve high speed communication, parallel processing is performed in the serial CRC. Since this method increases the circuit complexity, the speed gets limited. State space transformation is a method that can be used to reduce the circuit complexity. therefore, an efficient transformation matrix is needed in this method. In this paper, a method to construct a transformation matrix and an approximate searching algorithm to generate certain vectors, which are used in transformation matrix are implemented.
Overlap network communications and computations is a major requirement to ensure scalability of HPC applications on future exascale machines. To this purpose the de-facto MPI standard provides non-blocking routines fo...

the nonlinear plants with significant time delays are difficult to be controlled by classical means. In the present paper intelligent approaches are applied for the design of a nonlinear Smith predictor for compensation of the plant time delay based on a Takagi-Sugeno-Kang plant model and a fuzzy logic paralleldistributed compensation (PDC). the design and the advantages of the PDC-Smith are illustrated in temperature control. the good compensation of boththe plant time delay and nonlinearity results in faster system step responses in regard to a linear PI, a Smith and a PDC control systems.

Now a day's, cognitive radio networks (CRNs) is an emerging area of research in wireless communication paradigm. In CRN, the secondary user (SU) node exploits radio environment of primary user (PU) for spectrum holes and thus maximizes spectrum utilization. the communication and computation may be interfered by arbitrarily appearance of PU for its channel. However, it can be handled by increasing the size of available vacate channel set. the backup set for channels would help to avoid premature failure. therefore, the present work proposes a SU-NODES REPLACEMENT (SUNR) distributed algorithm for maintaining minimum spanning tree (MST) after single node failure in CRN. Our MST tree maintenance algorithm successfully tackles unpredictable disconnection and makes the protocol fault-tolerant. the correctness proof and simulation is included for algorithm verification.

this paper presents the fault tolerance and replica synchronization among storage server (Data-node) without the interference of metadata in Hadoop. It employs chunk list data structure which holds the information of relevant replicas stored in storage server. Whenever a client makes write request to the file stored on storage server, the replicas may become inconsistent and chances of getting fault increases. To improve the fault tolerance and replica synchronization, this paper has employed a new mechanism called Rapid replica synchronization. In this work, whenever the client puts write request, the one copy of replica will be updated first and then the remaining replica immediately gets update. During read request, the client will always get the modified data.
