Estimation of cost-effectiveness of poplar wood production in poplar plantations in Ravni Srem based on the method of pay back period [PDF]

open access: yesGlasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2011
Poplar plantations are a category of fixed assets in forestry, i.e. the assets with a biological character. They are related to their site, they are cultivated for a relatively long time and they have a relatively long utilization cycle, with the ...

Generalized S-Estimators [PDF]

open access: yesJournal of the American Statistical Association, 1994
Abstract In this article we introduce a new type of positive-breakdown regression method, called a generalized S-estimator (or GS-estimator), based on the minimization of a generalized M-estimator of residual scale. We compare the class of GS-estimators with the usual S-estimators, including least median of squares.

Effect of Synchronizing Coordinated Base Stations on Phase Noise Estimation [PDF]

open access: yes, 2013
In this paper, we study the problem of oscillator phase noise (PN) estimation in coordinated multi-point (CoMP) transmission systems. Specifically, we investigate the effect of phase synchronization between coordinated base stations (BSs) on PN ...

Target Association of Heterogeneous Sensors Based on Nearest-neighbor and Topology

open access: yesLeida xuebao, 2012
A new data association algorithm is proposed in this paper for heterogeneous sensors information fusion system, which consists of Radar and high-dynamic-range IR, based on joint usage of the nearest-neighbor (NN) and the topology similarity. The proposed

Robust Estimation of Optical Phase Varying as a Continuous Resonant Process [PDF]

open access: yes, 2013
It is well-known that adaptive homodyne estimation of continuously varying optical phase provides superior accuracy in the phase estimate as compared to adaptive or non-adaptive static estimation.

Parameter Estimation in a Noisy 1D Environment via Two Absorbing Receivers

open access: yes, 2020
This paper investigates the estimation of different parameters, e.g., propagation distance and flow velocity, by utilizing two fully-absorbing receivers (RXs) in a one-dimensional (1D) environment. The time-varying number of absorbed molecules at each RX

An efficient Monte Carlo approach for optimizing decentralized estimation networks constrained by undirected topologies [PDF]

open access: yes, 2009
We consider a decentralized estimation network subject to communication constraints such that nearby platforms can communicate with each other through low capacity links rendering an undirected graph.
