The Mw 7.9 Denali fault earthquake in central Alaska of 3 November 2002 triggered earthquakes across western North America at epicentral distances of up to at least 3660 km. We describe the spatial and temporal development of triggered activity in California and the Pacific Northwest, focusing on Mount Rainier, the Geysers geothermal field, the Long Valley caldera, and the Coso geothermal field...

The popularity of Peer-to-Peer (P2P) file sharing has resulted in large flows between different ISPs, which imposes significant transit fees on the ISPs in whose domains the communicating peers are located. The fundamental tradeoff faced by a peer-swarm is between free, yet delayed content exchange between intra-domain peers, and interdomain communication of content, which results in transit fe...

In order to facilitate cooperation between underwater robots, it is a must for robots to exchange information with unambiguous meaning. However, heterogeneity, existing in information pertaining to different robots, is a major obstruction. Therefore, this paper presents a networked ontology, named the Smart and Networking Underwater Robots in Cooperation Meshes (SWARMs) ontology, to address inf...

In this paper we address the problem of optimizing p2p systems for enterprise bandwidth cost savings. Consider a scenario where an enterprise uses p2p swarming to deliver content to its clients. A content may be a file or a package (bundle) of files. For popular and large content, our work finds that enterprise servers can exclusively rely on the cooperation among the peers in the form of a swa...

Cornelius Gysbert Dyke, MD (Fig 1), is widely acknowledged as the first American radiologist to devote his full professional effort to the field of neuroradiology. A brilliant diagnostician, careful and thorough, he established respect for the contributions of the neuroradiologist with the neuroclinicians of his time. More than anyone else then or for a number of years thereafter, he set the st...

Media Server Control Markup Language (MSCML) is a markup language used in conjunction with SIP to provide advanced conferencing functions. MSCML presents an application-level model for conference control, as opposed to device-level conference control models. One use of this protocol is for communications between a conference focus and mixer in the IETF SIP Conferencing Framework. Van Dyke, et a...

The collective dynamic behavior of large groups of interacting autonomous agents (swarms) have inspired much research in both fundamental and engineering sciences. It is now widely acknowledged that the intrinsic nonlinearities due to mutual interactions can generate highly collective spatio-temporal patterns. Moreover, the resulting self-organized behavior cannot be simply guessed by solely in...

Dyke-Davidoff-Masson Syndrome (DDMS) is a rare syndrome characterized with specific clinical and radiological findings due to involvement of the developing brain cerebral hemiatrophy one hemisphere. The was first described from Dyke, Davidoff Masson in 1933 series nine patients. has two forms, congenital acquired forms etiological factors vary brain. Most common symptom are focal or secondary g...

Ants use individual memory and pheromone communication to achieve effective collective foraging. We implement these strategies as distributed search algorithms in robotic swarms. Swarms of simple robots are robust, scalable and capable of exploring for resources in unmapped environments. We test the ability of individual robots and teams of three robots to collect tags distributed at random and...
