As reflected by the TOP500 list, hypercubes are popular interconnection networks for massively parallel systems, the main reason being the simplicity and ease of implementation of this network topology. In order to retain performance high and avoid bottleneck situation, routing algorithms are critical...

In this paper we propose an energy efficient clustering algorithm for maximizing the lifetime of WSNs. The proposed scheme decides the cluster head based on the energy level of the nodes, while tree topology is adopted to connect the nodes inside each cluster. A new model for deciding an optimal number...

Recently, SSD caching is widely studied for VM-based systems. In this paper we propose a novel hypervisor-based SSD caching scheme, employing a new metric to accurately determine the demand on SSD cache space of each VM. Computer simulation confirms that it substantially improves the accuracy of cache...

This paper proposes a hybrid approach of ontology and image clustering to automatically generate hierarchic image database. In the field of computer vision, ”generic object recognition” is one of the most important topics. Generic object recognition needs three types of research: feature extraction,...

Recent developments in radiation therapy have been focused on applications of charged particles, especially protons. Proton therapy can allow higher dose conformality compared to conventional radiation therapy. Over the years several dose calculation methods have been proposed in proton therapy. A common...

This paper proposes an efficient handover scheme considering the asymmetric characteristics of macro and pico cells in LTE-A HetNet. The proposed scheme detects a suitable target eNB for handover using a multi-criteria decision making algorithm and the mobility information of user equipment (UE). A prompt...

In this paper, we studied the problem of continuous reverse k nearest neighbors (RkNN) in directed road network, where a road segment can have a particular orientation. A RNN query returns a set of data objects that take query point as their nearest neighbor. Although, much research has been done for...
