Harm reduction among injecting drug users - evidence of effectiveness [PDF]

open access: yes, 2010
This chapter synthesises and evaluates the available direct evidence relating to the impact of needle and syringe programmes (NSPs), opioid substitution treatment (OST), drug consumption rooms (DCRs), and peer naloxone distribution (PND) on HIV/hepatitis

Survey on attribute and concept reduction methods in formal concept analysis [PDF]

open access: yes, 2023
Formal concept analysis (FCA) is now widely recognized as a useful approach for extracting, representing, and analyzing knowledge in various domains. The high computational cost of knowledge processing and the difficulty of visualizing the lattice are ...

On Multi-Step Look-Ahead Deadlock Prediction for Automated Manufacturing Systems Based on Petri Nets

open access: yesIEEE Access, 2020
Automated manufacturing systems (AMSs) are prone to be in deadlock states when resource allocation is unreasonable. Reasonably allocating system resources to achieve deadlock control is a primary task of the design of an AMS.

Combined Method Of Sight Reduction [PDF]

open access: yesTransNav, 2021
As ships and maritime transport have evolved, knowledge of navigation methods has also evolved, reaching today modern means that require less of the skills and time of navigators to determine the position of the ship on sees and oceans. However, the IMO

Variance reduction methods [PDF]

open access: yesProceedings of the 18th conference on Winter simulation - WSC '86, 1986
A computer simulation model is unusual in that the random error is under the total control of the experimenter. Variance reduction methods aim to take advantage of this to improve experimental accuracy. The fundamental ideas behind the most important of these methods will be described and illustrated with simple examples.

Model Order Reduction of Non-Linear Magnetostatic Problems Based on POD and DEI Methods [PDF]

open access: yes, 2014
In the domain of numerical computation, Model Order Reduction approaches are more and more frequently applied in mechanics and have shown their efficiency in terms of reduction of computation time and memory storage requirements. One of these approaches,

An intelligent genetic algorithm for PAPR reduction in a multi-carrier CDMA wireless system [PDF]

open access: yes, 2008
— A novel intelligent genetic algorithm (GA), called Minimum Distance guided GA (MDGA) is proposed for peak-average-power ratio (PAPR) reduction based on partial transmit sequence (PTS) scheme in a synchronous Multi-Carrier Code Division Multiple Access (

Resonant semilinear Robin problems with a general potential

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2017
We consider a semilinear Robin problem driven by the Laplacian plus an indefinite and unbounded potential. The reaction term is a Carath\'eodory function which is resonant with respect to any nonprincipal eigenvalue both at $\pm \infty$ and 0.
