On Adaptive Energy Efficient Transmission in WSNs
M. Tahir, N. Javaid, A. Iqbal +2
One of the major challenges in design of Wireless Sensor Networks (WSNs) is to reduce energy consumption of sensor nodes to prolong lifetime of finite-capacity batteries. In this p…
Solving Local Equivalence Problems with the Equivariant Moving Frame Method
Francis Valiquette
Given a Lie pseudo-group action, an equivariant moving frame exists in the neighborhood of a submanifold jet provided the action is free and regular. For local equivalence problems…
Divide-and-Rule Scheme for Energy Efficient Routing in Wireless Sensor Networks
K. Latif, A. Ahmad, N. Javaid +2
From energy conservation perspective inWireless Sensor Networks (WSNs), clustering of sensor nodes is a challenging task. Clustering technique in routing protocols play a key role…
The Betti numbers of Stanley-Reisner ideals of simplicial trees
Sara Faridi
We provide a simple method to compute the Betti numbers if the Stanley-Reisner ideal of a simplicial tree and its Alexander dual.
A Vast Thin Plane of Co-rotating Dwarf Galaxies Orbiting the Andromeda Galaxy
Rodrigo A. Ibata, Geraint F. Lewis, Anthony R. Conn +13
Dwarf satellite galaxies are thought to be the remnants of the population of primordial structures that coalesced to form giant galaxies like the Milky Way. An early analysis noted…
