In this paper, we study epidemic spreading on overlay networks in which n multiple sets of links interconnect among the same nodes. By using the microscopic Markov-chain approximation (MMA) approach, we establish the conditions of epidemic outbreak for two kinds of spreading mechanisms in such an overlay network: the concatenation case and the switching case. When a uniform infection rate is se...

We consider a model where commodity service providers are offering commodity computational services to a set of customers. We provide a solution for the efficient distribution of tasks by forwarding the service requests on an overlay network comprised on random cycles. We introduce algorithms for the creation, maintenance and repair of the overlay network. We discuss two algorithms, random wand...

Abstract Green Open Spaces (GOS) are an important component of the environment and, as a major spatial plan and area, play role in sustainability urban communities. The green area within zone is 30% total zone, according to Spatial Planning Act No 26/2007. Similarly, Act, his PU number 05/PRT/M/2008 describes guidelines for provision use open spaces areas. Public private included spaces. At lea...

In the past few years, overlay networks have received much attention but there has been little study on the “interaction” of multiple, co-existing overlays on top of a physical network. In addition to previously introduced concept of overlay routing strategy such as selfish routing, we introduce a new strategy called “overlay optimal routing”. Under this routing policy, the overlay seeks to min...

Many proteins contain flexible structures such as loops and hinged domains. A simple root mean square deviation (RMSD) alignment of two different conformations of the same protein can be skewed by the difference between the mobile regions. To overcome this problem, we have developed a novel method to overlay two protein conformations by their atomic coordinates using a Gaussian-weighted RMSD (w...

Longsor merupakan perpindahan massa tanah secara alami, longsor terjadi dalam waktu singkat dan dengan volume yang besar. adalah salah satu bencana alam merugikan, maka perlu adanya antisipasi satunya membuat peta kerentanan longsor. Penelitian ini bertujuan untuk mengetahui sebaran zona rawan pada daerah Banjarmasin, Kalimantan Selatan menggunakan teknik Boolean Weighted Overlay. Data digunaka...

A foundational issue underlying many overlay network applications ranging from routing to peer-to-peer file sharing is that of the network formation, i.e., folding new arrivals into an existing overlay, and rewiring to cope with changing network conditions. A typical overlay network for routing or content sharing, each node must select a fixed number of immediate overlay neighbors for routing t...
