Speech Title: Optimization on Replication Performance via Balance Quorum (BQ) and Data Center Selection Method (DCSM) Algorithms in Cloud Environment
Abstract: The cloud replication environment is an established and prominent technology globally recognized to deal with the issue of high-volume data that users are expected to access from anywhere at any time. Abundant researchers embarked their efforts to develop heterogeneous strategies to complement the ambiguities of cloud platform and system requirements. Regardless the resilient and durable service technologies provided by cloud providers, the limitation in respective cloud replication strategies are inevitable. The key issue is when acquired data demanded to be always accessible to users irrespective of time and location, appears to be crucial problem which is relative to, many inefficient system implementations. Therefore, we selected existing research work named “Dynamic Popularity aware Replication Strategy (DPRS)” and we concentrated on finding the research strength, gaps and limitations. A thorough case study was conducted via establishing re-simulation on DPRS algorithm and rigorous review was focused on the algorithm process flow. Subsequently, this study specifically reveals the limitations in particular algorithm and proposed potential area for improvements. The case study was simulated using simulation tools called, CloudSim. Finally, in order to enhance multi-performance in cloud replication environments, algorithms are presented as part of the proposed model which would explicitly contributes betterments in storage consumptions and network usage.

Speech Title: The Application of Compressive Sensing
Abstract: Compressive sensing / sampling (CS) is a new paradigm in the field of signal processing which has been widely applied in various applications. This theorem takes advantage of the sparse signal in the transformation region to reduce the sample size below the Shannon-Nyquist sampling rate. The main idea is that the number of information signals shows some structure or redundancy so that they can be used for signal acquisition and reconstruction simultaneously. The compressive sensing process aims to reduce the number of samples so that the data size becomes smaller, while the reconstruction process aims to restore the original data. Applying the right acquisition system will produce reconstruction results with good accuracy. Compressive sensing is widely used in several applications because it can improve system performance. In video processing and compression applications, it can significantly reduce the sampling rate. In monitoring internet network traffic, it can be used to detect traffic anomalies and reconstruct missing traffic. In a sensor network, it can co-reconstruct the intra-sensor and inter-sensor signals that come from separate measurements. Compressive sensing proves that a signal can be reconstructed spatially from information previously thought incomplete. This presentation discussed the use of CS in several applications, including monitoring internet traffic networks, telemedicine and audio watermarking.
