Energy-Aware Sink Node Localization Algorithm for Wireless Sensor Networks
International Journal of Distributed Sensor Networks, 2015 Wireless sensor networks (WSNs) are a family of wireless networks that usually operate with irreplaceable batteries. The energy sources limitation raises the need for designing specific protocols to prolong the operational lifetime of such networks ...

Cardinalities of topologies with small base
Annals of Pure and Applied Logic, 1994 Let T be the family of open subsets of a topological space (not necessarily Hausdorff or even T_0). We prove that if T has a base of cardinality <= mu, lambda <= mu < 2^lambda, lambda strong limit of cofinality aleph_0, then T has cardinality <= mu or >= 2^lambda. This is our main conclusion.

Topological dynamics on hyperspaces
Applied General Topology, 2010 In this paper we wish to relate the dynamics of the base map to the dynamics of the induced map. In the process, we obtain conditions on the endowed hyperspace topology under which the chaotic behaviour of the map on the base space is inherited by the ...

Topology optimisation: increasing the speed and reliability of design [PDF]
, 2014 In this paper, topology optimisation is applied to the design of the rear fuselage of an unmanned aerial vehicle (UAV). A comparison is drawn between the performance of a design created through evolutionary structural optimisation (ESO) and a baseline ...

Abelian torsion groups with a countably compact group topology
, 2010 Comfort and Remus [W.W. Comfort, D. Remus, Abelian torsion groups with a pseudo-compact group topology, Forum Math. 6 (3) (1994) 323-337] characterized algebraically the Abelian torsion groups that admit a pseudocompact group topology using the Ulm ...

Topology-Aware Line Densification for Reprojected Curves on Maps
, 2023 Many map features, such as administrative borders, coastlines, roads or rivers, are conventionally represented as polylines on a Cartesian plane. However, these objects are located on the curved surface of the Earth, necessitating an approximation when ...

New topology for voltage balancing in railway substations
, 2012 This paper deals with a new technique of voltage unbalance compensation for single phase railway substations. Using the concept of Chopper Controlled Impedance, the authors study the feasibility of an active Steinmetz circuit based on AC choppers.

Green virtual topology design algorithm based on constraint-based routing
Tongxin xuebao, 2014 To reduce the energy consumption of Internet core network, a formulation model for green virtual topology design (GVTD) problem was developed, which employs the following measures: traffic aggregation, network resources allocation on demand, virtual ...
