In this paper, we introduce a hybrid free-space optics/radio frequency (FSO/RF) networking paradigm for mobile robot teams. We believe that such a model will emerge as a consequence of inherent limitations of RF based approaches. FSO technology has the potential to provide tremendous increases in per-node throughput for a mobile ad-hoc network (MANET). To motivate this paradigm, we first provid...

OBJECTIVES Occlutech Figulla ASD Occluder (FSO) is an alternative device to Amplatzer Septal Occluder (ASO) with some structural innovations including increased flexibility, minimizing the amount of material implanted, and absence of the left atrial clamp. We aimed to report our experiences with FSO and compare the outcomes of this novel device versus ASO. INTERVENTIONS Between December 2005 ...

Abstract Background Understanding the habitat characteristics of endangered Siberian flying squirrel Pteromys volans is first step in conserving and managing forests it requires for nesting, gliding, feeding. Therefore, present study, we characterized habitats P. using GIS analysis 411 forest sites South Korea where fecal droppings were found. Results Fecal signs found various regions Korea, in...

Free space optics (FSO) is a promising solution for the need to very high data rate point-to point communication. FSO communication technology became popular due to its large bandwidth potential, unlicensed spectrum, excellent security and quick and inexpensive setup. Unfortunately, atmospheric turbulence-induced fading is one of the main impairments affecting FSO communications. To design a hi...

Title of Document: DESIGN AND ANALYSIS OF ADVANCED FREE SPACE OPTICAL COMMUNICATION SYSTEMS Sugianto Trisno, Doctor of Philosophy, 2006 Directed By: Professor Christopher C. Davis Department of Electrical and Computer Engineering Free space optical (FSO) communication has emerged as a viable technology for broadband wireless applications. FSO technology offers the potential of high bandwidth ca...

Attenuation and fading events can corrupt Free Space Optical (FSO) links. It would be so recommended to add mitigation error codes on the communication links. FSO channel can be described as an erasure channel (fading events can cause erasure errors), and we have identified in rateless codes (RCs) a suitable solution to be employed in FSO links. RCs do not need feedback and they add a redundant...
