The objective of this study is to improve the flexural performances of foam core sandwich composite via structural core modifications considering the ease of application. The performances of single core perforated and divided core perforated sandwich composites are compared with each other. The future demands of sandwich composites in recent years on aeronautics and marine industries are being increasing in their research needs and these materials has their superior properties for upgrading engineering products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sandwich%20composites" title="sandwich composites">sandwich composites</a>, <a href="https://publications.waset.org/abstracts/search?q=perforated%20cores" title=" perforated cores"> perforated cores</a>, <a href="https://publications.waset.org/abstracts/search?q=flexural%20test" title=" flexural test"> flexural test</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20and%20divided%20core%20perforated" title=" single and divided core perforated"> single and divided core perforated</a> </p> <a href="https://publications.waset.org/abstracts/128162/flexural-test-of-diversing-foam-core-sandwich-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128162.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">160</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Convex Restrictions for Outage Constrained MU-MISO Downlink under Imperfect Channel State Information</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Preetha%20Priyadharshini">A.

Priya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we consider the MU-MISO downlink scenario, under imperfect channel state information (CSI). The main issue in imperfect CSI is to keep the probability of each user achievable outage rate below the given threshold level. Such a rate outage constraints present significant and analytical challenges. There are many probabilistic methods are used to minimize the transmit optimization problem under imperfect CSI. Here, decomposition based large deviation inequality and Bernstein type inequality convex restriction methods are used to perform the optimization problem under imperfect CSI. These methods are used for achieving improved output quality and lower complexity. They provide a safe tractable approximation of the original rate outage constraints. Based on these method implementations, performance has been evaluated in the terms of feasible rate and average transmission power. The simulation results are shown that all the two methods offer significantly improved outage quality and lower computational complexity. <p class="card-text"><strong>Keywords:</strong> <a
