Detección de manos en imágenes de profundidad mediante el uso de bosques de decisión aleatorios
(Instituto Tecnológico de Costa Rica, 2015)
In the present work a system for hand detection in depth images is proposed. To perform
this task, the scene is segmented into 5 different classes: head, arms, body, hands and
background, using the pixel-wise classification ...
Sistema de tiempo real para el análisis de vibracion en puentes
(Instituto Tecnológico de Costa Rica, 2015)
This document proposes the development of a real-time embedded system for online
vibration analysis on bridges, where the main considerations of this analysis are presented,
as well as techniques to reduce power consumption ...
Optimización de protocolos de comunicación SDR ejecutados en FPGA
(Instituto Tecnológico de Costa Rica, 2015)
This project shows a methodology for the optimization digital communication systems implemented on
software radios SDR reducing the CPU and memory usage. The project was developed using the kit
Zedboard which is based ...
Electrical Impedance Tomography (EIT) image reconstruction for the human forearm
(Instituto Tecnológico de Costa Rica, 2016)
This thesis addresses the principles and algorithms of image reconstruction used
in electrical impedance tomography (EIT). It is a low cost, portable and non-invasive
medical imaging technique.
In this development EIT ...
Equivalent circuit modeling for electrochemical impedance spectroscopy
(Instituto Tecnológico de Costa Rica, 2013)
The design and fabrication of implantable neural electrodes is a challenge,
because the materials and interfaces must provide low impedance to the tissues,
with high current injection capabilities. In the Institute of ...
Escalamiento del cultivo de células en suspensión de Azadirachta indica (NEEM) en biorreactor tanque agitado para la produccion de azadiractina
(Instituto Tecnológico de Costa Rica, 2014)
The following Master’s Thesis engages in the area of NeuroMuscular Electrical
Stimulation (NMES), which comprises the activation of nerves and muscle fibers by
applying electrical current pulses using two electrodes ...
Active dictionary models: A framework for non-linear shape modeling
(Instituto Tecnológico de Costa Rica, 2015)
Shape modeling has applications in science and industry fields. The existing algorithms
are based on linear methods and on unimodal normal distributions not appropriate to
model deformations present in natural signals. ...
Sequential code parallelization for multi-core embedded systems: A survey of models, algorithms and tools
(Instituto Tecnológico de Costa Rica, 2014)
In recent years the industry experienced a shift in the design and manufacture of processors.
Multiple-core processors in one single chip started replacing the common used
single-core processors. This design trend reached ...

(Instituto Tecnológico de Costa Rica, 2014)
The following Master’s Thesis engages in the area of NeuroMuscular Electrical
Stimulation (NMES), which comprises the activation of nerves and muscle fibers by
applying electrical current pulses using two electrodes ...
Voltage drop tolerance by adaptive voltage scaling using clock-data compensation
(Instituto Tecnológico de Costa Rica, 2019)
El ruido de alta frecuencia en la red de alimentación compromete el rendimiento y la eficiencia energética de los sistemas electrónicos con microprocesadores, restringiendo la frecuencia máxima de operación de los sistemas ...
