Light Trails: A Sub-Wavelength Solution for Optical Networking

All-optical networks are able to transport data from source to destination entirely in the optical domain. This is a departure from current optical networks that rely on Optical-Electrical-Optical OEO conversion at each intermediate connection node to route data properly. The opacity inherent in traditional networks is costly in terms of...

On Multicasting in Wavelength-Routing Mesh Networks

This paper considers multicasting on wavelength-routing mesh optical networks. Although multicasting has been studied extensively in different network environments, multicasting in this environment is different, and more involved. The paper discusses the challenges of multicast support in optical wavelength routing networks, and reports on the advances made so far in...

Finding leaks in a spacecraft

With financial support from NASA, Iowa State University ISU engineers have developed a sensor to quickly find leaks in a spacecraft. This sensor locates an air leak by listening to the noise generated by the air rushing out of the leak and includes an array of 64 elements that detects...

Victim-Assisted Mitigation Technique for TCP-Based Reflector DDoS Attacks

This paper develops the concept of victim-assistance for Denial of Service DoS mitigation. The proposed concept is utilized within a simple, yet effective scheme designed for mitigating TCP-based reflector DoS attacks. The proposed scheme, called SYN number based filtering SNF, takes into account the TCP's connection establishment behavior and the...

A Service-Oriented Architecture for Electric Power Transmission System Asset Management

In electric power transmission systems, the assets include transmission lines, transformers, power plants and support structures. Maintaining these assets to reliably deliver electric energy at low prices is critical for a nation's growth and development. Towards this end, the authors describe a novel service-oriented architecture for sensing, information integration, risk...

Biodegradable plastics made from corn

Biodegradable plastics have already been created by using proteins from plants such as corn or soy. But they were not strong enough to be used by the industry. Now, researchers at Iowa State University have found a way to reinforce these biorenewable plastics. They are using high-powered ultrasonics to reinforce...

Load Balancing on Cluster-Based Multi Projector Display Systems

Sort-first or image space parallel rendering has been the subject of a significant amount of research. Its limited scalability is well known. Nevertheless, sort-first has noticeable advantages over other approaches: it has moderate and predictable communication overhead, and it has no problems with multipass or transparent rendering. Especially for multi-projector...

Should We Compare Web and Grid Services?

Earlier work in the areas of Service-Oriented Architecture SOA and Grid computing resulted in the Open Grid Services Infrastructure OGSI specification, which defined Grid services as an extension of Web services. As a result, people often try to understand the relationship between Grid and Web services or even compare between...
