In this paper, we propose an adaptive and opportunistic forwarding mechanism that is able to match mobility characteristics in Delay Tolerant Networks (DTNs). Our protocol, Seeker, empowers nodes with the ability to estimate future contact opportunities based on a history of pair-wise contacts. Furthermore, Seeker is able to adjust and rewind forwarding and buffering decisions on the fly. This ...

An open innovation strategy is increasingly being adopted by firms in order to leverage external knowledge sources to solve internal problems. However, there are challenges for firms to implement this strategy such as needing to identify, motivate, and manage external sources of innovation. Thus, innovation intermediaries such as InnoCentive are being established to assist client firms (seekers...

retrieval? It is legitimate for the reader to ask why a distinction is made by this book between the terms ‘interactive information retrieval’ and ‘information retrieval’. Surely, in the current context of information seeking through web search engines, it is clear that information retrieval necessarily involves some form of interaction between searcher and system. An answer to this question li...

The accuracy of target position detection in IR seeker depends on the accuracy of tracking error signal (TES) extraction from seeker Field of View (FOV). The type of reticle inside the seeker determines the output modulation signal that carries the TES. In this paper, the stationary wagon wheel reticle is used, which makes the type of the output signal as FM modulation in the linear region of F...

Ross-Hime Designs, Inc. presents the results of its research and development of “Low Cost Light-Weight Seeker Gimbals.” The Super Seeker, a patent-pending gimbal design, offers a swiveling yoke design lower in cost than current gimbal designs and weighing significantly less than traditional gimbal systems while enabling a doubling of the sensor’s surface area. The swiveling yoke design has buil...
