Meares-Irlen Syndrome is characterised by visual stress (visual discomfort) and visual perceptual distortions that can be alleviated by individually prescribed coloured filters. The benefit from coloured filters can be demonstrated with the Wilkins Rate of Reading Test (WRRT). Previous research using individually prescribed coloured overlays (sheets of plastic placed on a page) found that betwe...

OVERLAY MULTICAST FOR REAL-TIME DISTRIBUTED SIMULATION This report provides a top-level architecture for an overlay multicast service in support of distributed real-time virtual simulations over an open network environment. The top-level architecture for the overlay protocol was developed based on key concepts identified in the laboratory performance studies, the analytical model, and the studi...

Internet overlay services may exhibit poor performance when their designs ignore the topology and link properties of the underlying Internet substrate. Various service-specific techniques have been proposed to select good overlay links and thus enhance the performance. In this paper, we explore the model of providing a substrate-aware overlay structure management layer to assist the constructio...

Overlay networks are application-layer networks that are constructed using the existing Internet infrastructure. Nodes in an overlay network construct logical links toward other nodes to form an overlay topology. Common routing algorithms, such as the link state and distance vector algorithms, are then used to determine how to route data in the overlay network. Previous work has demonstrated th...

1 The frequent outbreak of severe foodborne diseases warns of a potential threat that the 2 global trade networks could spread fatal pathogens. The global trade network is a 3 typical overlay network, which compounds multiple standalone trade networks 4 representing the transmission of a single product and connecting the same set of 5 countries and territories through their own set of trade int...

Recently overlay networks have emerged as an efficient and flexible method for content distribution. An overlay network is a network running on top of another network, usually the Internet. This network is formed by a subset of underlying physical nodes. The connections between the overlay nodes are provided by overlay links, each of which is usually composed of one or more physical link. These...

The dynamic topology design is one of the important steps for the design of an overlay network. Traffic characteristic and volume, and behavior of nodes are the main issues that affect the performance of overlay networks, and have to be considered in designing a good topology. In this paper, we study the problem of designing the dynamic overlay topology based on estimating and predicting the Or...

In this poster proposal, we present Bos: a hierarchical geometric overlay multicast network that is built on a 2-tier hierarchical architecture called Lightweight SuperPeer Topologies (LST) [1], [2]. Bos makes use of the geometric connectivity and Minimum Spanning Trees (MST) properties of the LST overlay network to provide efficient overlay multicast. We evaluate Bos’s performance using the la...

While Portland cement concrete (PCC) overlay has been increasingly used as a rehabilitation technique for deteriorated PCC pavements in the last decade, reflective cracking places a major limit on its durability performance. The use of ultra ductile concrete named Engineered Cementitious Composite (ECC) should arrest such failure mode and greatly enhance the long term performance of the overlai...

Purpose – Peer-to-peer (P2P) streaming quickly emerges as an important application over the internet. A lot of systems have been implemented to support peer-to-peer media streaming. However, some problems still exist. These problems include non-guaranteed communication efficiency, limited upload capacity and dynamics of suppliers which are all related to the overlay topology design. The purpose...
