The main objective of this article is to evaluate the wind resource in the city of Floridablanca, Colombia. In Colombia, the supply of electrical energy comes mainly from hydroelectric mega-power stations, presenting generation problems in times of drought. The wind resource is an adequate alternative to diversify the electricity supply in the country. To analyze the characteristics of the wind, recorded measurements were carried out, every 15 minutes at a height of 30 m, throughout the year 2016, at a meteorological station located in Floridablanca, Colombia. In this study we present a statistical analysis of the wind characteristics in Floridablanca, Colombia, we applied a Weibull distribution of two parameters to model the wind speed and thus determine the wind potential. The average annual speed was 0.72 m / s with a standard deviation of 0.61 m / s. The monthly Weibull scale parameter varied from 0.52 m / s to 0.91 m / s, the monthly parameter varied from 0.98 to 1.37. The highest power density observed was 0.35 w / m ^ 2 in the months of February and August, the monthly average power density was 0.23 w / m ^ 2 which indicates a very poor wind potential considering that they are considered good wind potentials greater than 500 w / m ^ 2. This study contributes to evaluate the wind potential of Floridablanca, Colombia, and can be used, methodologically, to quantify the wind potential with possibilities of generating electric power in any part of the country.

Hydrogen production and purification was studied in a combined system including double catalytic bed reaction system. Steam Reforming of Ethanol (SRE) was performed in Ni/CeO2-ZrO2 catalyst and, subsequently, the reforming products gases passed through a second fixed bed containing Au/CeO2-ZrO2 catalyst in order to carry out the preferential CO oxidation (PROX-CO). Initially, the effect of temperature and the initial water concentration in the fed ethanol were evaluated to determine the conditions that maximize the H2/CO ratio while maintaining 100% conversion of ethanol. These requirements were accomplished when 25 mol% H2O and 4 mol% C2H5OH (steam/ethanol molar ratio = 7) were used. The catalyst stability was assessed under these reaction conditions at 600 oC, during more than 160 h on stream, obtaining ethanol conversions above 99% during the entire test and H2 productivity close to ideal. In the second part of the work, in order to obtain H2 grade PEM, the effect of O2 concentration in the feed stream on the selective CO oxidation using Au-CZ catalysts was investigated in the temperature range of 50-250 oC. Catalytic stability test was also performed. Characterization techniques: Temperature Programmed Reduction (TPR), X-Ray Diffraction (XRD), SEM-EDX, which confirmed the presence of a strong interaction between the mixed oxide support and the metal. In this study, we show a reaction system with double catalytic fixed bed in which hydrogen is obtained with the specifications required by PEM fuel cell. The tested materials exhibit high activity and selectivity towards hydrogen production and CO selective oxidation in the range of temperature studied

The pulse width prediction control technique has been widely used in AC-DC converters with power factor correction in boost topology, where satisfactory results have been reported without the need to use classic control laws. However, this technique has not been explored for other types of ACDC converters with power factor correction. In this work, the use of this technique is proposed in an AC-DC converter with power factor correction in a half-bridge boost topology. This topology presents high efficiency because it uses the least number of semiconductors compared to other topologies. In this technique the duty cycle is predicted by processing the average values of state and input variables of the converter in half bridge boost topology, using only four multiplications and five additions, which implies less complexity in its implementation. For its validation simulations were performed using MATLAB R simulink, where it was possible to observe values of power factor and THD comparable with other control methods such as non-linear carrier control, and conventional analog control, both reported in the literature.
脉冲宽度预测控制技术已被广泛应用于升压拓扑中具有功率因数校正的交直流变换器中，在不需要使用经典控制律的情况下，已经报道了令人满意的结果。然而，这种技术还没有探索其他类型的ACDC变换器的功率因数校正。在这项工作中，提出了在半桥升压拓扑中具有功率因数校正的AC-DC转换器中使用该技术。与其他拓扑结构相比，这种拓扑结构使用最少的半导体，因此具有较高的效率。在该技术中，通过处理半桥升压拓扑中变换器的状态和输入变量的平均值来预测占空比，仅使用4次乘法和5次加法，这意味着其实现的复杂性较低。为了验证其有效性，使用MATLAB R simulink进行仿真，可以观察到功率因数和THD值与其他控制方法(如非线性载波控制和传统模拟控制)的可比性，这两种控制方法均在文献中报道过。

The growing demand for building materials requires the development of environmentally friendly materials with excellent use properties and reasonable prices. One of the major objectives of materials research in the construction industry is the use of renewable resources from waste materials from industries for the development of new building materials. The current trend of thermal insulation of buildings has resulted in the development of materials for insulation based on renewable resources of agriculture. This article describes the research and development of insulation materials based on natural fibres of agricultural origin; in particular, guadua fibres, sugar cane, hemp, flax and jute.

The aim of this project consists in designing and implementing a short-range, low-cost K band, continuous wave radar prototype system for industrial applications with the K-LC6 module, capable of measuring distance and radial speed. This article describes all the hardware and software design, manufacture, and implementation considerations of the radar system. To minimize the cost of a potential product for industry, prototype hardware was implemented by using commercial elements. This work also shows the result of experimental tests that permitted characterizing the prototype and verifying measurements of distance and speed of targets in laboratory environments. These tests permitted verification of its operation, obtaining a short-range (from 0.6 to 63 m) frequency modulated - continuous wave radar prototype, capable of measuring speeds up to 9.2 km/h

Hand position and gesture recognition from an image stream is a topic of relevance for developing human-machine interactions. The advent of low-cost cameras in the consumer market, like Microsoft Kinect, leaves open the possibility of build recognition applications, which are not affected by low light conditions. This paper is a survey of the literature on hand position and gesture recognition with the use of depth cameras. It is noticeable that reviewed papers focus on the recognition of one-handed gestures and their classification among a finite set of gestures. Last year’s advances in hand processing include techniques for posture recognition without restrictions, but it is unknown their effectiveness on low-cost hardware because testing were done without a standardized set of images and with a diversity of hardware.

New alternatives and feedstocks have been identified to overcome the impact caused by combustion of fossil fuels; some of them point on the promotion of second, third and fourth generation biofuels resulting from non-edible crops and other raw materials. The lack of information about the performance of engines used for power generation encumbers the use of chicken fat biodiesel in gensets in rural areas or other applications in which power generation is the main purpose. Therefore, this work aims to identify the incidence of using chicken fat biodiesel on the performance of a 13.45kWe internal combustion engine employed for power generation. The biodiesel was synthesized in lab conditions and afterwards fueled in the engine. Parameters such as the total electrical efficiency, heat rate, fuel consumption and the exhaust gas emissions are analyzed. A Lister TR2 diesel engine fixed to a Leroy Soner LSA 38 M/J electrical generator was employed. The chicken fat biodiesel was successfully produced in a lab-scale facility and afterward employed as biofuel blended with commercial biodiesel BPa7. The efficiency of the genset increases up to 38.79% with B22.5 higher than the 35.08% obtained for B0. As a consequence of the fuel reduction and addition of a sustainable biofuel such as chicken-fat biodiesel the carbon footprint was also decreased; the CO2 released decreases about 2.9 kgCO2h-1 when the genset was operating at full capacity fueled with B22.5
