Audio communication in its most natural form, the face-to-face conversation, is binaural. Current telecommunication systems often provide only monaural audio, stripping it of spatial cues and thus deteriorating listening comfort and speech intelligibility. In this work, the application of binaural audio in telecommunication through audio augmented reality (AAR) is presented. AAR aims at augment...

This contribution proposes for Recommendation G.812 (1) a holdover specification for Clock Type II that is consistent with the current specification of 10 per day and is not broken into aging, temperature, and initial offset components and (2) a modification to the output wander TDEV mask, to apply only to Types II and III, to make the mask consistent with the respective wander generation TDEV ...

Coğrafi Bilgi Sistemleri (CBS) ve Uzaktan Algılama (UA) yöntemleri çok uzun süredir tarım, haritacılık, hidroloji, jeoloji, madencilik, ormancılık, çevre, şehircilik, afet yönetimi arkeoloji gibi farklı faaliyet alanlarında, disiplinler arası iş birliğine dayalı olarak yöntemlerle birlikte kullanılmaktadır. UA tarafında mekânsal, spektral, radyometrik zamansal çözünürlüğe sahip algılayıcılardan...

Key management plays fundamental role in research on security service in wireless sensor networks (WSNs). However, due to the resource constraints, establishing pairwise keys in WSNs is not a trivial tasks. Several exiting key management schemes have been proposed in literature to establish pairwise keys between sensor nodes, but they either can not offer strong resilience against node capture ...

ECLIPSE is a next-generation virtual telecommunication network that provides multimedia services that integrate voice, video, text, and images. ECLIPSE facilitates the modular decomposition of new telecommunication services. In this paper we sketch the challenges we face in making ECLIPSE highly available when running on top of a heterogenous and widely distributed system. We describe how we ap...
