(American Society of Mechanical Engineers (ASME), 2015)This paper presents the development of an exergy and thermoeconomic analysis of a wheat flour agro-industrial plant, which was aimed to evaluate the energy use and establish the operation cost of its components, and to ... -
Thermoeconomic indicators ofair conditioning in a river ship to change the configuration of their thermal insulation
(American Society of Mechanical Engineers (ASME), 2014)This work has as object of study the energy of a river ship air conditioning system performance, using fiberglass, polyurethane or rockwool as insulation. Thermoeconomics Indicators based on second law of thermodynamics ... -
Thermoplastic Starch (TPS)/Polylactic Acid (PLA) Blending Methodologies: A Review
(Cartagena de IndiasCampus TecnológicoIngeniería Mecánica, 2021-06-17)Polylactic acid (PLA) and thermoplastic starch (TPS) are biodegradable polymers of biological origin, and the mixture of these polymers has been studied due to the desirable mechanical properties of PLA and the low processing ... -
Three-dimensional multimodal medical imaging system based on freehand ultrasound and structured light
(Cartagena de Indias, 2021-05-21)We propose a three-dimensional (3D) multimodal medical imaging system that combines freehand ultrasound and structured light 3D reconstruction in a single coordinate system without requiring registration. To the best of ... -
Through-glass interposer integrated high quality RF components
(Institute of Electrical and Electronics Engineers Inc., 2014)High quality and compact RF devices, using the half mode substrate integrated waveguide (HMSIW) architecture loaded with a complementary split ring resonator (CSRR), are implemented on a glass interposer layer, which ... -
Time-Domain Analysis for Current Control in Single-Phase Distribution Networks Using SMES Devices With PWM-CSCs
(Taylor and Francis Inc., 2018)This paper presents a time-domain analysis for current control in single-phase distribution networks using superconducting magnetic energy storage devices connected through pulse-width modulated current source converters. ... -
Topological Invariants of Principal G-Bundles with Singularities
(Pleiades Publishing, 2018)principal G-bundle with singularities is a principal bundle π: P¯ → M with structure group G¯ which reduces to a subgroup G ⊂ G¯ on the set M \ Σ, where M is an n-dimensional compact manifold and Σ ⊂ M is a k-dimensional ... -
Toward an adaptive protection scheme in active distribution networks: Intelligent approach fault detector
(Cartagena de Indias, 2021-01)Conventional protection schemes have proven insufficient for the protection of Active Distribution Networks (ADN). Novel protection schemes with an adaptive approach should be developed to guarantee the protection of ADN ... -

Toward an automatic 3D measurement of skin wheals from skin prick tests
(SPIE, 2019)The skin prick test (SPT) is the standard method for the diagnosis of allergies. It consists in placing an array of allergen drops on the skin of a patient, typically the volar forearm, and pricking them with a lancet to ... -
Toward the generation of reproducible synthetic surface data in optical metrology
(Cartagena de Indias, 2020-05-19)The implementation and generation of synthetic data for testing algorithms in optical metrology are often difficult to reproduce. In this work, we propose a framework for the generation of reproducible synthetic surface ... -
Towards better BBB passage prediction using an extensive and curated data set
(Wiley-VCH Verlag, 2015)In the present report, the challenging task of drug delivery across the blood-brain barrier (BBB) is addressed via a computational approach. The BBB passage was modeled using classification and regression schemes on a novel ... -
Trade-Off Asymmetric Profile for Extended-Depth-of-Focus Ocular Lens
(Cartagena de Indias, 2022-02-19)We explore the possibility of extending the depth of focus of an imaging lens with an asymmetric quartic phase-mask, while keeping the aberration within a relatively low level. This can be intended, for instance, for ... -
Trajectory-tracking control of a planar parallel robot using generalized predictive control with constraints
(Cartagena de Indias, 2020)This paper presents the generalized predictive control with constraints, implemented to a planar parallel robot in order to calculate and track the desired trajectory of the end-effector of this robot. The manipulator is ... -
Transient dynamic analysis of shear deformable shallow shells using the boundary element method
(Elsevier Ltd, 2015)The complexity involved in the dynamic response of plates brings many challenges from a mathematical standpoint. In this work, the transient dynamic analysis of elastic shallow shells under uniformly distributed pressure ... -
Transient phenomena during the emptying process of a single pipe with water–air interaction
(Taylor and Francis Ltd., 2019)Emptying pipelines can be critical in many water distribution networks because subatmospheric pressure troughs could cause considerable damage to the system due to the expansion of entrapped air. Researchers have given ... -
Transient phenomena generated in emptying operations in large-scale hydraulic pipelines
(Cartagena de Indias, 2020-08-18)Air pockets generated during emptying operations in pressurized hydraulic systems cause significant pressure drops inside pipes. To avoid these sudden pressure changes, one of the most widely used methods involves the ...
