Seawalls are vital for protecting coastal areas. However, the seabed in front of seawalls may undergo severe scouring. This can result destabilization seawall structure, underlying mechanisms which remains unclear. Therefore, an integrated observation system consisting acoustic and optical instruments was deployed areas with used to observe sediment dynamics elements such as waves, currents, ti...

We examined structural changes in the molluscan community for ten years (2001-2010) before and five years (2011-2015) after the 2011 Great East Japan Earthquake and subsequent tsunami around Matsushima Bay, Miyagi Prefecture, northeastern Japan. Before the earthquake and tsunami, Ruditapes philippinarum, Macoma incongrua, Pillucina pisidium, and Batillaria cumingii were dominant, and an alien p...

In cloud networks, sharing network resources among different VMs is critical to performance isolation. A sharing scheme aims to fully utilize the network resource, and effectively prevent performance interference and even malicious attacks such as Denial-of-Service (DoS) attacks. Existing bandwidth allocation schemes like Seawall attempt to achieve performance isolation on a per-link basis. How...
