(Institute of Electrical and Electronics Engineers Inc., 2019)© 2018 IEEE. Dual-VENC strategies have been proposed to improve the velocity-to-noise ratio in phase-contrast MRI. However, they are based on aliasing-free high-VENC data. The aim of this paper is to propose a dual-VENC ...

(Springer, 2016)We study the problem of designing a data structure that reports the positions of the distinct τ -majorities within any range of an array A[1, n], without storing A. A τ -majority in a range A[i, j ], for 0 < τ < 1, is ...

(SIAM, 2016)This paper studies the bioremediation, in minimal time, of a water resource or reservoir using a single continuous bioreactor. The bioreactor is connected to two pumps, at different locations in the reservoir, that pump ...
-
(Elsevier, 2017)The fleet for surface transit in urban areas - number of buses and vehicle size - is usually determined by the characteristics of demand during the peak period, adjusting frequencies for other periods where those characteristics ...
-
(Springer, 2018)This work presents strategies for fractional order model reference adaptive control (FOMRAC) and fractional order proportional-integral-derivative control (FOPID) applied to an automatic voltage regulator (AVR). The paper ...

(ACM, 2015)Sequence representations supporting the queries access, select, and rank are at the core of many data structures. There is a considerable gap between the various upper bounds and the few lower bounds known for such ...
-
(ELSEVIER, 2008-09-01)In recent years, there has been a growing trend to out-source service operations in which the equipment maintenance is carried out by an external agent rather than in-house. Often, the agent (service provider) offers more ...
-
(Informs, 2016)We study the design of mechanisms for a sequencing problem where the types of job-agents consist of processing times and waiting costs that are private to the jobs. In the Bayes-Nash setting, we seek to find a sequencing ...
-
(Institute of Electrical and Electronics Engineers Inc., 2018)This paper presents a heuristic model that optimally deploys the resources used to obtain a metropolitan and neighborhood area network with connectivity between the central office of an electricity company and the integrated ...
-
(MDPI, 2020)We describe an algorithm computing an optimal prefix free code for n unsorted positive weights in time within O(n(1+lg alpha))subset of O(nlgn), where the alternation alpha is an element of[1..n-1] approximates the minimal ...
-
(Elsevier, 2016)Travelcards are used in many parts of the developed world as a form of payment for public transport that is convenient for frequent users. In essence it involves a one-time payment T at the beginning of a period that covers ...
-
(Universidad de Chile, 2022)En este trabajo se estudian tres problemas. Primero, se resuelve el problema de un vendedor dotado de infinitas unidades de cierto producto homogéneo para la venta en un horizonte finito y discreto con el fin de maximizar ...
-
(Univ. Bath., 2015)In this paper, marginal cost-pricing rules are applied to an agent-based model. User-specific optimal bus fares are estimated by simulating user interactions at a microscopic level. We consider external effects of prolonged ...
-
(ELSEVIER, 2006-02)In this article, we develop a model to help a maintenance decision making situation of a given equipment. We propose a novel model to determine optimal life-cycle duration and intervals between overhauls by minimizing ...
-
(Springer Science+Business Media, 2014)This paper proposes a multi-criteria approach that accounts for the risk of fire when determining the optimal rotation of a forest stand that is being managed for both timber production and carbon sequestration purposes. ...
-
(Universidad de Chile, 2021)La inferencia de parámetros orbitales para sistemas binarios es extremadamente importante para el estudio evolutivo del universo, puesto que dichos parámetros orbitales permiten inferir las masas individuales de los ...
-
(2007)A recent trend to improve the effectiveness of similarity queries in multimedia databases is based on dynamic combinations of metric spaces. The efficiency issue when using these dynamic combinations is still an open ...
