Hop-by-Hop Frame Aggregation for VoIP on Multi-Hop Wireless Networks
2008 IEEE International Conference on Communications, 2008The already severe inefficiency problem in running VoIP on the IEEE 802.11-based wireless LAN is exacerbated in multi-hop networks due to spatial interference. This paper presents a novel scheme that significantly mitigates the effect of the interference by combining the inter-call aggregation and the pseudo-broadcast technique as used in network ...

Hop-by-Hop Beamforming for Dual-Hop MIMO AF Relay Networks
2011 IEEE International Conference on Communications (ICC), 2011A comprehensive performance analysis of dual-hop multiple-input multiple-output amplify-forward relay networks with hop-by-hop beamforming is presented. The impact of practical transmission impairments; (i) feedback delays, (ii) channel estimation errors and (iii) spatially-correlated fading on the system performance is studied.

Drug Discovery Today: Technologies, 2004
The aim of scaffold hopping is to discover structurally novel compounds starting from known active compounds by modifying the central core structure of the molecule. Scaffold hopping is a central task of modern medicinal chemistry requiring a multitude of techniques, which are discussed in this article.

Proceedings Sixth Heterogeneous Computing Workshop (HCW'97), 2002
We describe a novel framework for early detection and isolation of security violations in heterogeneous environments, based on real-time service hopping. In distributed client-server systems, service hopping fills a role analogous to frequency-hopping spread-spectrum techniques for secure wireless communication.

The American Mathematical Monthly, 1999
The dynamical behavior of a massless hoop with an attached point mass under the influence of gravity is an old chestnut, with some surprising features, including the question of whether or not it can "hop". It appears in Littlewood's Miscellany [1] and most recently in this MONTHLY [2].

Hops and the Hop-Pickers of the Midlands
Folk Life, 1991AbstractIn this country in ancient times it is thought that the hop herb grew wild among the hedgerows and the willow. The cultivated hop plant which we are familiar with today was introduced into this country in the sixteenth century from Belgium/France/Germany areas, although King Henry VIII banned it during his reign.
