Ubiquity and large intersections properties under digit frequencies constraints
, 2009
"... digit frequencies constraints ..."
GPS-Less Low Cost Outdoor Localization for Very Small Devices.
- IEEE Personal Communications Magazine,
, 2000
"... Abstract-Instrumenting the physical world through large networks of wireless sensor nodes, particularly for applications like environmental monitoring of water and soil, requires that these nodes be very small, light, untethered and unobtrusive. The problem of localization, i.e., determining where ..."

a given node is physically located in a network is a challenging one, and yet extremely crucial for many of these applications. Practical considerations such as the small size, form factor, cost and power constraints of nodes preclude the reliance on GPS (Global Positioning System) on all nodes
Multi-Robot Area Patrol under Frequency Constraints
"... This paper discusses the problem of generating patrol paths for a team of mobile robots inside a designated target area. Patrolling requires an area to be visited repeatedly by the robot(s) in order to monitor its current state. First, we present frequency optimization criteria used for evaluation ..."

directionality and velocity constraints. Robots are positioned uniformly along this path, using a second algorithm. Moreover, the solution is guaranteed to be robust in the sense that uniform frequency of the patrol is achieved as long as at least one robot works properly.
Bridge Topology Optimisation with Stress, Displacement and Frequency Constraints
"... The principal stress based Evolutionary Structural Optimisation (ESO) method is presented herein for topology optimisation of arch, tied arch, cable-stayed and suspension bridges with both stress and displacement constraints. Two performance index formulas are developed to determine the efficiency o ..."

of the topology design. A refined mesh scheme is proposed to improve the details of the final topology without resorting to the complete analysis of a finer mesh. Furthermore, cable-supported bridges are optimised with frequency constraint incorporating the "nibbling " technique. The applicability
Optimization of Skeletal Buildings under Frequency Constraints
"... Abstract—The main goal of the present work is to decrease the computational burden for optimum design of steel frames with frequency constraints using a new type of neural networks called Wavelet Neural Network. It is contested to train a suitable neural network for frequency approximation work as t ..."

Optimal string mining under frequency constraints
- Closed Sets for Labeled Data?, PKDD, 2006
, 2006
"... Abstract. We propose a new algorithmic framework that solves frequency-related data mining queries on databases of strings in optimal time, i.e., in time linear in the input and the output size. The additional space is linear in the input size. Our framework can be used to mine frequent strings, eme ..."

Space-Efficient String Mining under Frequency Constraints
"... Let D1 and D2 be two databases (i.e. multisets) of d strings, over an alphabet Σ, with overall length n. We study the problem of mining discriminative patterns between D1 and D2 — e.g., patterns that are frequent in one database but not in the other, emerging patterns, or patterns satisfying other f ..."

frequency-related constraints. Using the algorithmic framework by Hui (CPM 1992), one can solve several variants of this problem in the optimal linear time with the aid of suffix trees or suffix arrays. This stands in high contrast to other pattern domains such as itemsets or subgraphs, where super
MODULATION FREQUENCY CONSTRAINTS ON WOW AND FLUTTER DETERMINATION
, 2007
"... Hitherto developed algorithms for wow and flutter characteristic determination were found useful in some real-life restoration procedures, however, there was no study of their capabili-ties in terms of the maximal parasite modulation frequency that can be determined with their application. This pape ..."

Pushing Frequency Constraint to Utility Mining Model
"... Abstract. Traditional association rules mining (ARM) only concerns the frequency of itemsets, which may not bring large amount of profit. Utility mining only focuses on itemsets with high utilities, but the number of rich-enough customers is limited. To overcome the weakness of the two models, we pr ..."
