Hexagonal filters for ultrasound images
(2014)Most of the devices for acquisition and display of medical images use rectangular lattices even though there are other sampling strategies that can be more efficient in terms of resolution. This paper proposes an approach ... -
Hierarchical agglomerative clustering of time-warped series
(Springer Verlag, 2018)We have developed a procedure for hierarchical agglomerative clustering of time series data. To measure the dissimilarity between these data, we use classically the Euclidean distance or we apply the costs of the series ... -
Hierarchical Control for DC Microgrids Using an Exact Feedback Controller with Integral Action
(Cartagena de Indias, 2022-02-06)This paper addresses the problem of the optimal stabilization of DC microgrids using a hierarchical control design. A recursive optimal power flow formulation is proposed in the tertiary stage that ensures the global ... -
High impedance fault modeling and location for transmission line
(Cartagena de Indias, 2021-04-07)A fault in a power system generates economic losses, security problems, social problems and can even take human lives. Therefore, it is necessary to have an efficient fault location strategy to reduce the exposure time ... -

Higher-order kinematic analyses of a planar parallel robot based on screw theory
(Cartagena de Indias, 2020)This paper presents the higher-order kinematic analyses of a planar parallel robot, addressed by means of the theory of screws. The reduced velocity, acceleration, jerk and hyper-jerk state for the end-effector of robot ... -
Highly compact surface micromachined metamaterial circuits using multilayers of low-loss Benzocyclobutene for microwave and millimeter wave applications
(2012)This work explores the implementation of highly compact three dimensional (3D) integrable metamaterial based transmission lines on a low resistivity CMOS grade silicon substrate for microwave and millimeter wave applications. ... -
Highway Planning Trends: A Bibliometric Analysis
(Cartagena de Indias, 2022)An efficient highway infrastructure network is a determining factor in promoting the socio-economic development of countries and regions. Highway planning activities are highly important because their results ensure that ... -

HoloEasy, a web application for computer generated holograms
(Springer Verlag, 2018)If the appropriate phase and/or amplitude profile is placed on a Diffractive Optical Element (DOE) it can practically generate an image of an object (hologram) by diffraction of the light. The problem of generating computer ... -
How do the affective and symbolic factors of private car driving influence car users’ travel behavior in a car restriction policy scenario?
(Cartagena de Indias, 2023)The number of private car trips a person makes is usually linked to external factors such as economic incentives or disincentives, legislation, infrastructure, and the quality of transport systems, among others. The impact ... -
How evolving network access and network management technologies are redefining the competitive wireless markets
(2011)This paper examines some of the key problems users encounter when accessing current generation wireless networks. Using a case study of a hypothetical user, the authors explore the emerging services and the new broadband ... -
How to manage generations? An Approach based on the Quality of Work Life
(IBIMA Publishing, 2019)The objectives of this research are to examine whether there are significant differences in the perception of quality of work life among employees of three generational cohorts (i.e., Baby Boomers, Generation Xers and ... -
Hölder continuous maps on the interval with positive metric mean dimension
(Cartagena de IndiasCampus Tecnológico, 2023-11)Fix a compact metric space X with finite topological dimension. Let C0(X) be the space of continuous maps on X and Hα(X) the space of α-Hölder continuous maps on X, for α ∈ (0, 1]. Let H1(X) be the space of Lipschitz ... -

Humor styles across 28 countries
(Springer, 2019)Responses to a measure of the four humor styles of affiliative, aggressive, self-enhancing, and self-defeating from the Humor Styles Questionnaire (HSQ; Martin et al. Journal of Research in Personality, 37(1), 48–75, 2003) ... -
Hybrid calibration method for improving 3D measurement accuracy of structured light systems
(Cartagena de Indias, 2020-08-21)In structured-light systems, the lens distortions of the camera and the projector reduce the measurement accuracy when calibrated as a standard stereo-vision system. The conventional compensation via distortion coefficients ... -
Hybrid calibration procedure for fringe projection profilometry based on stereo vision and polynomial fitting
(Cartagena de IndiasIngeniería Mecatrónica, 2020-03-19)The key to accurate 3D shape measurement in fringe projection profilometry (FPP) is the proper calibration of the measurement system. Current calibration techniques rely on phase-coordinate mapping (PCM) or back-projection ... -
