Estimation of tropical soils’ hydraulic properties with inverse method and tension infiltrometer field data

open access: yesRevista Ambiente & Água, 2020
In the last few years, many studies have been published by authors from several countries offering approximations and use of the inverse method. However, the unique environmental conditions and distinct properties of the tropical soils in Brazil require ...

Evaluation of RPL’s Single Metric Objective Functions [PDF]

open access: yes, 2017
In this paper, we evaluate the performance of RPL (IPv6 Routing Protocol for Low Power and Lossy Networks) based on the Objective Function being used to construct the Destination Oriented Directed Acyclic Graph (DODAG).

Application of piecewise-linear approximation of probabilistic-time characteristics of queuing systems

open access: yesКосмические аппараты и технологии, 2020
Nowadays many modern industries depend on satellite technologies to a greater or lesser extent. To build such satellite communication systems it is necessary to have estimated parameters of high service quality, one including the information delay time ...

A symmetric objective function for ICP

open access: yesACM Transactions on Graphics, 2019
The Iterative Closest Point (ICP) algorithm, commonly used for alignment of 3D models, has previously been defined using either a point-to-point or point-to-plane objective.

Quantum circuit design for objective function maximization in gate-model quantum computers [PDF]

open access: yesQuantum Information Processing, 2018
Gate-model quantum computers provide an experimentally implementable architecture for near-term quantum computations. To design a reduced quantum circuit that can simulate a high-complexity reference quantum circuit, an optimization should be taken on ...

Reliability impact for optimal placement of power factor correction capacitors considering transient switching events

open access: yesThe Journal of Engineering, 2019
The power factor can be enhanced in many ways, one of which is a capacitor installation to correct the power factor at a particular location. While power factor correction capacitors are commonly used in power systems to generate Mvar at the bus, this ...

Optimising a nonlinear utility function in multi-objective integer programming [PDF]

open access: yes, 2012
In this paper we develop an algorithm to optimise a nonlinear utility function of multiple objectives over the integer efficient set. Our approach is based on identifying and updating bounds on the individual objectives as well as the optimal utility ...

Static and Dynamic Community Detection Methods That Optimize a Specific Objective Function: A Survey and Experimental Evaluation

open access: yesIEEE Access, 2020
Most current survey papers classify community detection methods into broad categories and do not draw clear boundaries between the specific techniques employed by these methods. We survey in this paper all fine-grained community detection categories, the

Partial Evaluation and Efficient Discarding for the Maximal Covering Location Problem

open access: yesIEEE Access, 2021
The maximal covering location problem attempts to locate a limited number of facilities in order to maximize the coverage over a set of demand nodes. This problem is NP-Hard and it has been often addressed by using metaheuristics, where the execution ...
