have been focused on two main components: data extraction and selection and the second one is the analysis performed over the obtained data. The goal of this paper is to analyze the influence that each of these components has over the system performance by evaluating detection over network scenarios with different setups. The independent variables are as follows: the number of system inputs, the way the inputs are codified and the complexity of the analysis techniques. For the analysis, some approaches of artificial neural networks are implemented with different number of layers. The obtained results show the influence that each of these variables has in the system performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=network%20intrusion%20detection" title="network intrusion detection">network intrusion detection</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20network" title=" artificial neural network"> artificial neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=anomaly%20detection%20module" title="anomaly detection module">anomaly detection module</a> </p> <a href="https://publications.waset.org/abstracts/2047/evaluating-performance-of-an-anomaly-detection-module-with-artificial-neural-network-implementation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2047.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">342</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">270</span> Predictive Maintenance Based on Oil Analysis Applicable to Transportation Fleets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Israel%20Ibarra%20Solis">Israel Ibarra Solis</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Carlos%20Rodriguez%20Sierra"> Juan Carlos Rodriguez Sierra</a>, <a href="https://publications.waset.org/abstracts/search?q=Ma.%20del%20Carmen%20Salazar%20Hernandez"> Ma. del Carmen Salazar Hernandez</a>, <a href="https://publications.waset.org/abstracts/search?q=Isis%20Rodriguez%20Sanchez"> Isis Rodriguez Sanchez</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Perez%20Guerrero"> David Perez Guerrero</a> </p> <p class="card-text"><strong>Abstract:</strong></p> At the present paper we try to explain the analysis techniques use for the lubricating oil in a maintenance period of a city bus (Mercedes Benz Boxer 40), which is call ‘R-24 route’, line Coecillo Centro SA de CV in Leon Guanajuato, to estimate the optimal time for the oil change.

Also, the development of technology is focused on obtaining energetic products from renewable sources. In this study, a thermodynamic model including Exergy balance and a subsequent Life Cycle Assessment (LCA) were carried out for four subsystems of the integrated gasification-combustion of pinewood. Results of exergy analysis and LCA showed the process feasibility in terms of exergy efficiency and global energy efficiency of the life cycle (GEELC). Moreover, the energy return on investment (EROI) index was calculated. The global exergy efficiency resulted in 67 %. For pretreatment, reaction, cleaning, and electric generation subsystems, the results were 85, 59, 87, and 29 %, respectively. Results of LCA indicated that the emissions from the electric generation caused the most damage to the atmosphere, water, and soil. GEELC resulted in 31.09 % for the global process. This result suggested the environmental feasibility of an integrated gasification-combustion system. EROI resulted in 3.15, which determinates the sustainability of the process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exergy%20analysis" title="exergy analysis">exergy analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20assessment%20%28LCA%29" title=" life cycle assessment (LCA)"> life cycle assessment (LCA)</a>, <a href="https://publications.waset.org/abstracts/search?q=renewability" title=" renewability"> renewability</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/139076/exergetic-and-life-cycle-assessment-analyses-of-integrated-biowaste-gasification-combustion-system-a-study-case" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139076.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">213</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">268</span> Comparison of Effects over the Autonomic Nervous System When Using Force Training and Interval Training in Indoor Cycling with University Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Botero">Daniel Botero</a>, <a href="https://publications.waset.org/abstracts/search?q=Oscar%20Rubiano"> Oscar Rubiano</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20P.%20Barragan"> Pedro P.

However, there are few studies analyzing the impact of these training over the autonomic nervous system (ANS). This work has aimed to compare the activity of the autonomic nervous system, when is expose to an IT or ST indoor cycling mode. After approval by the ethics committee, a cross-over clinical trial with 22 healthy participants (age 21 ± 3 years) was implemented. The selection of participants for the groups with sequence force-interval (F-I) and interval-force (I-F) was made randomly with assignation of 11 participants for each group. The temporal series of heart rate was obtained before and after each training using the POLAR TEAM® heart monitor. The evaluation of the ANS was performed with spectral analysis of the heart rate variability (HRV) using the fast Fourier transform (Kubios software). A training of 8 weeks in each sequence (4 weeks with each training) with an intermediate period of two weeks of washout was implemented for each group. The power parameter of the HRV in the low frequency band (LF = 0.04-0.15Hz related to the sympathetic nervous system), high frequency (HF = 0.15-0.4Hz, related to the parasympathetic) and LF/HF (with reference to a modulation of parasympathetic over the sympathetic), were calculated. Afterward, the difference between the parameters before and after was realized. Then, to evaluate statistical differences between each training was implemented the method of Wellek (Wellek and Blettner, 2012, Medicine, 109 (15), 276-81). To determine the difference of effect over parasympathetic when FT and IT are used, the T test is implemented obtaining a T value of 0.73 with p-value ≤ 0.1. For the sympathetic was obtained a T of 0.33 with p ≤ 0.1 and for LF/HF the T was 1.44 with a p ≥ 0.1. Then, the carry over effect was evaluated and was not present. Significant changes over autonomic activity with strength or interval training were not observed. However, a modulation of the parasympathetic over the sympathetic can be observed. Probably, these findings should be explained because the sample is little and/or the time of training was insufficient to generate changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autonomic%20nervous" title="autonomic nervous">autonomic nervous</a>, <a href="https://publications.waset.org/abstracts/search?q=force%20training" title=" force training"> force training</a>, <a href="https://publications.waset.org/abstracts/search?q=indoor%20cycling" title=" indoor cycling"> indoor cycling</a>, <a href="https://publications.waset.org/abstracts/search?q=interval%20training" title=" interval training"> interval training</a> </p> <a href="https://publications.waset.org/abstracts/95284/comparison-of-effects-over-the-autonomic-nervous-system-when-using-force-training-and-interval-training-in-indoor-cycling-with-university-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95284.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">225</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">267</span> The Clinical Significance of Cutaneous Leishmaniasis in Immigrant and Refugee Populations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Promise%20Ufomadu">Promise Ufomadu</a>, <a href="https://publications.waset.org/abstracts/search?q=Edgar%20Rodriguez"> Edgar Rodriguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Grace%20Lee"> Grace Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cutaneous Leishmaniasis (CL) is an infection caused by a variety of Leishmania species which are protozoan organisms that are typically carried by sandflies found in tropical regions.

It is a branched shrub that belongs to the family Asteraceae, has oval leaves of 6 to 11 cm in length and also has small yellow flowers. In Mexico, the tarbush is a very appreciated plant because it has been used as a traditional medicinal agent, for the treatment of gastrointestinal diseases, skin infections and as a healing agent. This plant has been used mainly as an infusion. Due to its traditional use, the content and type of phytochemicals present in the plant are currently unknown and are responsible for its biological properties, so its recovery and identification is very important because the compounds that it contains have relevant applications in the field of food, pharmaceuticals and medicine. The objective of this work was to determine the best extraction condition of phytochemical compounds (mainly polyphenolic compounds) from the leaf using ultrasound/microwave assisted extraction (U/M-AE). To reach the objective, U/M-AE extractions were performed evaluating three mass/volume ratios (1:8, 1:12, 1:16), three ethanol/water solvent concentrations (0%, 30% and 70%), ultrasound extraction time of 20 min and 5 min at 70°C of microwave treatment. All experiments were performed using a fractional factorial experimental design. Once the best extraction condition was defined, the compounds were recovered by liquid column chromatography using Amberlite XAD-16, the polyphenolic fraction was recovered with ethanol and then evaporated. The recovered polyphenolic compounds were quantified by spectrophotometric techniques and identified by HPLC/ESI/MS. The results obtained showed that the best extraction condition of the compounds was using a mass/volume ratio of 1:8 and solvent ethanol/water concentration of 70%. The concentration obtained from polyphenolic compounds using this condition was 22.74 mg/g and finally, 16 compounds of polyphenolic origin were identified. The results obtained in this work allow us to postulate the Mexican plant known as tarbush as a relevant source of bioactive polyphenolic compounds of food, pharmaceutical and medicinal interest. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=U%2FM-AE" title="U/M-AE">U/M-AE</a>, <a href="https://publications.waset.org/abstracts/search?q=tarbush" title=" tarbush"> tarbush</a>, <a href="https://publications.waset.org/abstracts/search?q=polyphenols" title=" polyphenols"> polyphenols</a>, <a href="https://publications.waset.org/abstracts/search?q=identification" title=" identification"> identification</a> </p> <a href="https://publications.waset.org/abstracts/102851/ultrasoundmicrowave-assisted-extraction-recovery-and-identification-of-bioactive-compounds-polyphenols-from-tarbush-fluorensia-cernua" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102851.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">163</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">265</span> The Collaboration between Resident and Non-resident Patent Applicants as a Strategy to Accelerate Technological Advance in Developing Nations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hugo%20Rodr%C3%ADguez">Hugo Rodríguez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Migrations of researchers, scientists, and inventors are a widespread phenomenon in modern times.

An interesting case is synchronized with master-slave configuration in star topology. Nodes of these networks are modeled for the laser and simulated by Matlab. These results are applicable to private communication. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chaotic%20laser" title="chaotic laser">chaotic laser</a>, <a href="https://publications.waset.org/abstracts/search?q=network" title=" network"> network</a>, <a href="https://publications.waset.org/abstracts/search?q=star%20topology" title=" star topology"> star topology</a>, <a href="https://publications.waset.org/abstracts/search?q=synchronization" title=" synchronization"> synchronization</a> </p> <a href="https://publications.waset.org/abstracts/34528/synchronization-of-semiconductor-laser-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34528.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">566</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">263</span> BIASS in the Estimation of Covariance Matrices and Optimality Criteria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20M.%20Rodriguez-Diaz">Juan M.

However, this measure can underestimate the true variance, specially for small samples. Traditionally, optimal design theory pays attention to this variance through its relationship with the model's information matrix. For this reason it seems convenient, at least in some cases, adapt the optimality criteria in order to get the best designs for the actual variance structure, otherwise the loss in efficiency of the designs obtained with the traditional approach may be very important. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=correlated%20observations" title="correlated observations">correlated observations</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20matrix" title=" information matrix"> information matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=optimality%20criteria" title=" optimality criteria"> optimality criteria</a>, <a href="https://publications.waset.org/abstracts/search?q=variance-covariance%20matrix" title=" variance-covariance matrix "> variance-covariance matrix </a> </p> <a href="https://publications.waset.org/abstracts/31104/biass-in-the-estimation-of-covariance-matrices-and-optimality-criteria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31104.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">443</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">262</span> Electricity Consumption and Economic Growth: The Case of Mexico</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mario%20G%C3%B3mez">Mario Gómez</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Carlos%20Rodr%C3%ADguez"> José Carlos Rodríguez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The causal relationship between energy consumption and economic growth has been an important issue in the economic literature.

Snacking is part of the day-to-day lives of people, however, most of the snacks have a high saturated fat, salt and refined sugar content; these dietary factors are believed to have negative health consequences. For this reason, there has been an increase in consumer demand for healthy, natural and convenient foods, so the development of a significant portion of new products focuses on improving the nutritional value of food snacks through modification its nutritional composition. In this paper, a new product made from vegetables has been designed.

The calculations were performed using the first-principles pseudo-potential method within the framework of spin density functional theory (DFT). Our calculations predict that for Bi concentrations greater than ~70%, the WZ structure is more favorable than the NaCl one and that for x = 0 (pure MgO), x = 0.25 and x = 0.50 of Bi concentration the NaCl structure is more favorable than the WZ one. For x = 0.75 of Bi, a transition from wurtzite towards NaCl is possible, when the pressure is about 22 GPa. Also It has been observed the crystal lattice constant closely follows Vegard’s law, that the bulk modulus and the cohesion energy decrease with the concentration x of Bi. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DFT" title="DFT">DFT</a>, <a href="https://publications.waset.org/abstracts/search?q=Mg1-xBixO" title=" Mg1-xBixO"> Mg1-xBixO</a>, <a href="https://publications.waset.org/abstracts/search?q=pseudo-potential" title=" pseudo-potential"> pseudo-potential</a>, <a href="https://publications.waset.org/abstracts/search?q=rock-salt" title=" rock-salt"> rock-salt</a>, <a href="https://publications.waset.org/abstracts/search?q=wurtzite" title=" wurtzite"> wurtzite</a> </p> <a href="https://publications.waset.org/abstracts/24781/first-principles-investigation-of-the-structural-and-electronic-properties-of-mg1-xbixo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24781.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">525</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">252</span> Comparing ITV Definitions From 4D CT-PET and Breath-Hold Technique with Abdominal Compression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20D.%20Esposito">R.

Naturally released into the environment through the weathering and erosion of sulphides mineral, some activities such as mining, the use of pesticides or wood preservatives potentially increase the concentration of arsenic in air, water, and soil. The natural arsenic release of a geological material is a threat to the world's drinking water sources. In aqueous phase is found in inorganic form, as arsenate and arsenite mainly, the contamination of groundwater by salts of this element originates what is known as endemic regional hydroarsenicism. The International Agency for Research on Cancer (IARC) categorizes the inorganic As within group I, as a substance with proven carcinogenic action for humans. It has been found the presence of As in groundwater in several countries such as Argentina, Mexico, Bangladesh, Canada and the United States. Regarding the concentration of arsenic in drinking water according to the World Health Organization (WHO) and the Environmental Protection Agency (EPA) establish maximum concentrations of 10 μg L⁻¹. In Mexico, in some states as Hidalgo, Morelos and Michoacán concentrations of arsenic have been found in bodies of water around 1000 μg L⁻¹, a concentration that is well above what is allowed by Mexican regulations with the NOM-127- SSA1-1994 that establishes a limit of 25 μg L⁻¹. Given this problem in Mexico, this research proposes the use of a natural Mexican zeolite (clinoptilolite type) native to the district of Etla in the central valley region of Oaxaca, as an adsorbent for the removal of arsenic. The zeolite was subjected to a conditioning with iron oxide by the precipitation-impregnation method with 0.5 M iron nitrate solution, in order to increase the natural adsorption capacity of this material. The removal of arsenic was carried out in a column with a fixed bed of conditioned zeolite, since it combines the advantages of a conventional filter with those of a natural adsorbent medium, providing a continuous treatment, of low cost and relatively easy to operate, for its implementation in marginalized areas. The zeolite was characterized by XRD, SEM/EDS, and FTIR before and after the arsenic adsorption tests, the results showed that the modification methods used are adequate to prepare adsorbent materials since it does not modify its structure, the results showed that with a particle size of 1.18 mm, an initial concentration of As (V) ions of 1 ppm, a pH of 7 and at room temperature, a removal of 98.7% was obtained with an adsorption capacity of 260 μg As g⁻¹ zeolite. The results obtained indicated that the conditioned zeolite is favorable for the elimination of arsenate in water containing up to 1000 μg As L⁻¹ and could be suitable for removing arsenate from pits of water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=arsenic" title=" arsenic"> arsenic</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20conditioning" title=" iron conditioning"> iron conditioning</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20zeolite" title=" natural zeolite"> natural zeolite</a> </p> <a href="https://publications.waset.org/abstracts/89747/natural-mexican-zeolite-modified-with-iron-to-remove-arsenic-ions-from-water-sources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89747.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">172</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">245</span> Reflections on the Role of Cultural Identity in a Bilingual Education Program</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lina%20Tenjo">Lina Tenjo</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilba%20Rodr%C3%ADguez"> Ilba Rodríguez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The role of cultural identity in bilingual programs has been barely discussed in regards to SLA. This research focuses on providing relevant information that helps in having more knowledge about the experiences that an elementary student has during the second language learning process in a bilingual program within a multicultural context. This study explores the experience of 18 students in a dual language program, in a public elementary school in Northern Virginia, USA. It examines their dual language experience and the different ways this experience contributes to the formation of their cultural identity. The findings were studied with the purpose of determining the relationship between participants and certain aspects of cultural identity in a multicultural context. The reflections that originate from the voices of children are the key source that helps us to better understand the particular needs that young learners have during their participation in a DLP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acculturation" title="acculturation">acculturation</a>, <a href="https://publications.waset.org/abstracts/search?q=bilingual%20education" title=" bilingual education"> bilingual education</a>, <a href="https://publications.waset.org/abstracts/search?q=culture" title=" culture"> culture</a>, <a href="https://publications.waset.org/abstracts/search?q=dual%20language%20program" title=" dual language program"> dual language program</a>, <a href="https://publications.waset.org/abstracts/search?q=identity" title=" identity"> identity</a>, <a href="https://publications.waset.org/abstracts/search?q=second%20language%20acquisition" title=" second language acquisition"> second language acquisition</a> </p> <a href="https://publications.waset.org/abstracts/59189/reflections-on-the-role-of-cultural-identity-in-a-bilingual-education-program" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59189.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">339</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">244</span> Complexity in Managing Higher Education Institutions in Mexico: A System Dynamics Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Carlos%20Rodr%C3%ADguez">José Carlos Rodríguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mario%20G%C3%B3mez"> Mario Gómez</a>, <a href="https://publications.waset.org/abstracts/search?q=Medardo%20Serna"> Medardo Serna</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper analyses managing higher education institutions in emerging economies.

The obtained abundance of minerals of the sample studied is very near to the ones obtained using XRD with a total relative error of 2%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hyperspectral%20imaging" title="hyperspectral imaging">hyperspectral imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20noise%20fraction" title=" minimum noise fraction"> minimum noise fraction</a>, <a href="https://publications.waset.org/abstracts/search?q=MNF" title=" MNF"> MNF</a>, <a href="https://publications.waset.org/abstracts/search?q=simplex%20growing%20algorithm" title=" simplex growing algorithm"> simplex growing algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=SGA" title=" SGA"> SGA</a>, <a href="https://publications.waset.org/abstracts/search?q=standard%20normal%20variance" title=" standard normal variance"> standard normal variance</a>, <a href="https://publications.waset.org/abstracts/search?q=SNV" title=" SNV"> SNV</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20dimension" title=" virtual dimension"> virtual dimension</a>, <a href="https://publications.waset.org/abstracts/search?q=XRD" title=" XRD"> XRD</a> </p> <a href="https://publications.waset.org/abstracts/131834/virtual-dimension-analysis-of-hyperspectral-imaging-to-characterize-a-mining-sample" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131834.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">242</span> Production of Bioethanol through Hydrolysis of Agro-Industrial Banana Crop Residues</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S%C3%A1nchez%20Acu%C3%B1a">Sánchez Acuña</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Camilo"> Juan Camilo</a>, <a href="https://publications.waset.org/abstracts/search?q=Granados%20G%C3%B3mez"> Granados Gómez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mildred%20Magaly"> Mildred Magaly</a>, <a href="https://publications.waset.org/abstracts/search?q=Navarrete%20Rodr%C3%ADguez"> Navarrete Rodríguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Luisa%20Fernanda"> Luisa Fernanda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, the main biofuels source production as bioethanol is food crops. This means a high competition between foods and energy production. For this reason, it is necessary to take into account the use of new raw materials friendly to the environment. The main objective of this paper is to evaluate the potential of the agro-industrial banana crop residues in the production of bioethanol. A factorial design of 2<sup>4</sup> was used, the design has variables such as pH, time and concentration of hydrolysis, another variable is the time of fermentation that is of 7 or 15 days. In the hydrolysis phase, the pH is acidic (H<sub>2</sub>SO<sub>4</sub>) or basic (NaOH), the time is 30 or 15 minutes and the concentration is 0.1 or 0.5 M. It was observed that basic media, low concentrations, fermentation, and higher pretreatment times produced better performance in terms of biofuel obtained. <p
