20 años de la comercialización mundial de cultivos biotecnológicos
(2016-11)The use of living organisms to obtain goods and services for humans is known as biotechnology. From these improvements are achieved such as higher nutritional quality, drought tolerance, pest resistance, and more. This ... -
30-Gb/s Optical Link Combining Heterogeneously Integrated III–V/Si Photonics With 32-nm CMOS Circuits
(Institute of Electrical and Electronics Engineers Inc., 2015-02)We present a silicon photonics optical link utilizing heterogeneously integrated photonic devices driven by low-power advanced 32-nm CMOS integrated circuits. The photonic components include a quantum-confined Stark effect ... -
3D scanning and detection of objects for a subsequent manipulation by a collaborative robot
(Instituto Tecnológico de Costa Rica, 2016)The present document is a brief description of what the project "3D scanning and detection of objects for a subsequent manipulation by a collaborative robot" will be about, and how the solution will be approached. The ... -
A CFD parametric study on the performance of a low-temperature-differential γ-type Stirling engine
(Elsevier Ltd, 2015-12)An in-house CFD code has been applied to a low-temperature-differential (LTD) γ-type Stirling engine to understand the effects posed by several geometrical and operational parameters on engine performance. The results ... -
A deep learning algorithm to address kinship verification integrating age transformation techniques applied to the family images and model tuning methodologies
(Instituto Tecnológico de Costa Rica, 2024-11-28)This thesis addresses the challenge of verifying familial relationships through facial features, which is often complicated by age-related variations. Traditional kinship verification models struggle to account for these ... -
A deep reinforcement learning approach to multistage stochastic network flows for distribution problems
(Instituto Tecnológico de Costa Rica, 2022-05-27)Distribution networks are a crucial part of supply chains that often entail highly complex optimization problems. An NP-hard example is minimizing the longterm transportation cost of multiple kinds of goods over a time ... -
A fault-tolerance protocol for parallel applications with communication imbalance
(IEEE, 2015)The predicted failure rates of future supercomputers loom the groundbreaking research large machines are expected to foster. Therefore, resilient extreme-scale applications are an absolute necessity to effectively use ... -
A Magnus Wind Turbine Power Model Based on Direct Solutions Using the Blade Element Momentum Theory and Symbolic Regression
(IEEE, 2017-01)A model of the power coefficient of a mid-scale Magnus wind turbine using numerical solutions of the Blade Element Momentum Theory and symbolic regression is presented. A direct method is proposed for solving the nonlinear ... -
A methodology for automated design and implementation of complex analog and digital CMOS integrated circuits applying a genetic algorithm and a CAD tool for multiobjective optimization.
(Instituto Tecnológico de Costa Rica, 2014)This dissertation proposes an automated methodology to design and optimize electronic integrated circuits, something that could be called simulation-driven optimization. The concept of Pareto optimality or the so called ...
