ABSTRACT: During disaster response, key resources are supplied from a variety of channels including: government agencies, volunteer organizations, commercial businesses, educational institutions and others. While these entities have efficient internal methods of communication and coordination, interorganizational collaboration has often been hindered by political, social, and technological challenges. This paper examines the challenges to collaboration among responding entities and proposes a technology-enabled self-synchronization framework for sharing information using a distributed, highly scalable, web application based on the cloud computing technologies. The proposed design applies the unique benefits of cloud computing to the disaster response domain. This notional design facilitates communication among a broad range of public and private groups without requiring these organizations to compromise competitive advantage.

ABSTRACT: Effective designs rarely emerge from good structural design or aesthetics alone. It is more often the result of the end product's overall design integrity. Added to this, design is inherently an interdisciplinary collaborative activity. With this in mind, today's tools are not powerful enough to design complex physical environments, such as command control centers or hospital operating theaters. This paper presents the concept of employing projector-based augmented reality techniques to enhance interdisciplinary design processes.

ABSTRACT: We have recently designed, fabricated and implanted a visual prosthesis. Animal studies show that the implant remains viable post- op. There exist numerous challenges to move the implant from the bench o the bedside and requires a concerted effort from scientists in different disciplines to come together. We hope that in the future that we will eventually take the important step being able to perform human studies to understand the efficacy of a chronic retinal implant.

ABSTRACT: The application of PCB integrated electroplated cores for VRM inductors is proposed, where the motivation is to increase frequencies beyond 1 MHz so that VRM transient response can be improved. It is shown that electroplated alloys have loss properties that are at least competitive with those of the highest frequency ferrite material available. Various PCB integrated inductor designs are presented, with toroidal cores providing the smallest solution. Measured losses under non-sinusoidal operating conditions are provided and work is ongoing to characterise the materials further.

ABSTRACT: A wireless retinal implant with a low-power area-efficient stimulator chip features an ASK demodulator, single-ended-to-differential converter, low-power DLL and programmable current drivers. The chip dissipates 1.3mW from plusmn2.5V at a data rate of 100kb/s. The chip is powered and driven through a wireless inductive link separated by 15mm

ABSTRACT: Semiconductor gas sensors have a proven potential for low cost and highly sensitive gas detection. However, selectivity remains one of the main problems for many applications. We report a new kind of mesoporous ceramic filter with nanoscale pores. The ceramic filter offers mechanical protection and can help to boost selectivity enormously through selective gas absorption. The developed nano-technological filters are based on mesoporous secondary and ternary silicon nitride derivatives with a defined particle size and are prepared via a new sol gel route. The interaction of the filters with CO, NO<sub>2</sub>, H<sub>2</sub> and propane were evaluated using broadband sensors. Highly selective absorption was observed for different gases, especially NO<sub>2</sub>. From these experiments a filter efficiency value is calculated, which allows easy selection of suitable filter materials for different applications.
