HEED: A Hybrid, Energy-Efficient, Distributed Clustering Approach for Ad Hoc Sensor Networks
- IEEE TRANS. MOBILE COMPUTING
, 2004
"... Topology control in a sensor network balances load on sensor nodes and increases network scalability and lifetime. Clustering sensor nodes is an effective topology control approach. In this paper, we propose a novel distributed clustering approach for long-lived ad hoc sensor networks. Our proposed ..."

according to a hybrid of the node residual energy and a secondary parameter, such as node proximity to its neighbors or node degree. HEED terminates in Oð1Þ iterations, incurs low message overhead, and achieves fairly uniform cluster head distribution across the network. We prove that, with appropriate
Arbitrary placement of secondary nodes, and error control, IN THE MESHLESS LOCAL PETROV- GALERKIN (MLPG) METHOD
- COMPUTER MODELING IN ENGINEERING & SCIENCES
, 2000
"... The truly meshless local Petrov-Galerkin (MLPG) method holds a great promise in solving boundary value problems, using a local symmetric weak form as a natu-ral approach. In the present paper, in the context of MLPG and the meshless interpolation of a moving least squares (MLS) type, a method which ..."

The secondary nodes can be placed at any location where one needs to obtain a better res-olution. The sub-domains for the shape functions in the MLS approximation
Locality-Aware Request Distribution in Cluster-based Network Servers
, 1998
"... We consider cluster-based network servers in which a front-end directs incoming requests to one of a number of back-ends. Specifically, we consider content-based request distribution: the front-end uses the content requested, in addition to information about the load on the back-end nodes, to choose ..."

, to choose which back-end will handle this request. Content-based request distribution can improve locality in the back-ends' main memory caches, increase secondary storage scalability by partitioning the server's database, and provide the ability to employ back-end nodes that are specialized
Distributed Clustering in Ad-hoc Sensor Networks: A Hybrid, Energy-Efficient Approach
, 2004
"... Prolonged network lifetime, scalability, and load balancing are important requirements for many ad-hoc sensor network applications. Clustering sensor nodes is an effective technique for achieving these goals. In this work, we propose a new energy-efficient approach for clustering nodes in adhoc sens ..."

sensor networks. Based on this approach, we present a protocol, HEED (Hybrid Energy-Efficient Distributed clustering), that periodically selects cluster heads according to a hybrid of their residual energy and a secondary parameter, such as node proximity to its neighbors or node degree. HEED does
Local similarity in RNA secondary structures
, 2003
"... We present a systematic treatment of alignment distance and local similarity algorithms on trees and forests. We build upon the tree alignment algorithm for ordered trees given by Jiang et. al (1995) and extend it to calculate local forest alignments, which is essential for finding local similar reg ..."

regions in RNA secondary structures. The time complexity of our algorithm is O(|F1 | ·|F2 | ·deg(F1) · deg(F2) · (deg(F1) +deg(F2)) where |Fi | is the number of nodes in forest Fi and deg(Fi) is the degree of Fi. We provide carefully engineered dynamic programming implementations using dense, two
Spectrum Leasing to Cooperating Secondary ad hoc Networks
- IEEE JSAC
, 2008
"... Abstract—The concept of cognitive radio (or secondary spectrum access) is currently under investigation as a promising paradigm to achieve efficient use of the frequency resource by allowing the coexistence of licensed (primary) and unlicensed (secondary) users in the same bandwidth. According to th ..."

to the property-rights model of cognitive radio, the primary terminals own a given bandwidth and may decide to lease it for a fraction of time to secondary nodes in exchange for appropriate remuneration. In this paper, we propose and analyze an implementation of this framework, whereby a primary link has
Efficient Locking for Concurrent Operations on B-Trees
- ACM Transactions on Database Systems
, 1981
"... The B-tree and its variants have been found to be highly useful (both theoretically and in practice) for storing large amounts ofinformation, especially on secondary storage devices. We examine the problem of overcoming the inherent difficulty of concurrent operations on such structures, using a pra ..."

Mice lacking expression of secondary lymphoid organ chemokine have defects in lymphocyte homing and dendritic cell localization
, 1999
"... Secondary lymphoid organ chemokine (SLC) is expressed in high endothelial venules and in T cell zones of spleen and lymph nodes (LNs) and strongly attracts naive T cells. In mice homozygous for the paucity of lymph node T cell (plt) mutation, naive T cells fail to home to LNs or the lymphoid regions ..."
