Towards A System For Controlling Client-Server Traffic In Virtual Worlds Using Sdn, Jason Anderson, Jim Martin

Publications

Scaling virtual worlds in the age of cloud computing is complicated by the problem of efficiently directing client-server traffic in the face of agile and dynamic compute resources. In this proposed model, Software Defined Networking and compact encoding of avatar data in packet headers are combined to make a fast, scalable, high capacity proxy server that can hide the server infrastructure while fitting well with the IaaS paradigm of modern cloud providers.

Linear Model Estimation Of Nonlinear Systems Using Least-Squares Algorithm5, Alireza Rahrooh, Walter W. Buchanan, Remzi Seker

Publications

This paper presents utilizes Least-Squares Algorithm to obtain more accurate linear models of nonlinear systems using parameter estimation. This approach generates an optimal linear model which is valid over a wide range of trajectories and converges to the desired steady-state value with no errors unlike the existing techniques. The proposed technique is very efficient and does not require storing the data. Therefore, it can easily be used and implemented with limited resources for undergraduate curriculum especially in underdeveloped countries. Most available techniques for linearization of nonlinear system are only valid about the operating point; furthermore, the knowledge of the operating …

Visualising Museum Stories, Eoin Kilfeather

Publications

Storytelling is fundamental to our ability to understand, and find meaning in, the world around us. Stories allow us to organise and share knowledge, and to identify the relationships between objects, events, and experiences. Within museums stories allow visitors to engage with collections and to gain meaningful understanding of museum objects. Stories transform a collection of objects into a meaningful knowledge structure that connects the objects and give them meaning.

This paper describes the Open Source Storyscope system that has been developed by the EU FP7 DECIPHER project. Storyscope's workspace and tools allow museum professionals and visitors to research, develop, …
