Análisis comparativo del desempeño de los formatos de modulación RZ-DQPSK y RZ-PDPSK frente a Técnicas de Compensación Ópticas de la Dispersión Cromática en Redes DWDM a 10 Gbps
Authors: Herrera Varona Juan David , Toledo Noguera Jennifer Tatiana , Tovar Alejandro Toledo
Published: August 2018

During the transport of information through an optical fi ber-based network, various signal distortions can occur. One of these distortions is the chromatic dispersion which generates delays or spectral broadening of the optical pulses as they propagate through the fi ber causing an overlap with their adjacent pulses, whereby the use of compensation techniques is necessary. This article analyzes the optical compensation techniques of chromatic dispersion in a DWDM network for 10 Gbps, in order to propose the best configuration for redressal and to consolidate knowledge that can help operators to define solutions to support new requirements.

Published: August 2018

This article presents the results of a specific methodology used with some programming courses where we conform groups of students with diff erent characteristics looking to improve the individual learning level in the learning process of computer programming in a Systems Engineer program. The target of this research was to explore an easy way to learn based on cooperation and collaboration between students. We realized tests in the programming courses by dividing the group in two subgroups based on some determined parameters. We conclude that the results bring a special light to consider as important inside the learning process of engineers so the experience could be very useful in other engineering programs and other areas.

Published: August 2018

This research aimed to establish the relationship of learning styles with the repetition and retardation academic of students in Biomedical, Electronic, and Industrial Engineering programs. The CHAEA questionnaire was applied to a sample of 69 students enrolled in the period 2016-1, to identify the predominant learning styles. To establish the levels of academic repetition and retardation academic, the academic report data available at the institution were consulted. To obtain the results of the relationship between learning styles with retardation and academic repetition we used the Pearson correlation. The results showed that in terms of learning styles they followed this order: high preference for the theoretical style and moderate preference in both active, refl exive and pragmatic styles. In addition, a statistically significant relationship was found between repetition and retardation academic.

Published: August 2018

In this work, a modal analysis was applied on a bioepoxy/ fi ber composite material using the simulation (Finite Elements), experimentation and analytical modeling knowing the deviation between each of the methods of the solution. The material was elaborated using a bioepoxy resin and fi que fi bers in the distribution of weave under the technique of manufacturing the infusion vacuum. Tensile tests were performed on the composite material according to ASTM D3039 / D3039M to obtain the mechanical properties that allow the development of the mathematical model and the simulation and analysis of scanning electron microscopy to observe the adhesion between the fi ber and the matrix. The experimental modal analysis was performed by measuring the frequency response (FRF) under ISO 7626-2. The Euler-Bernoulli equation was used for analytical modeling, while the ANSYS fi nite element software was used for the simulation. It concludes that for the fi rst modes of material vibration obtained results close between the three methods, however for the third mode the error increases by the interaction between the matrix and the fi ber and the eff ects of the rotation of the cross-section of the test item.

Authors: López Rodríguez Diego Fernando , Rojas González Andrés Felipe
Published: August 2018

This paper presents a general review of the use of plastic and lignocellulosic waste in the production of Wood Plastic Composites (WPC). Wood-Plastic Composites are proposed as a solution to the growing generation of waste. Diff erent mixtures of polymer matrices (plastics) and vegetable reinforcements (lignocellulosic residues) have been evaluated for the WPC production. The mixing of this type of raw material is mainly done using three types of technologies: extrusion, injection and compression molding. It was found that changes in the mechanical properties of the fi nal product depend on the raw material type, the particle size and the fiber proportion used, as well as the addition of binding agents. In the same way, variations in the water absorption capacity, densifi cation and thermal stability of the fi nal compound are reported to increase the amount of fi ber in the mixture.

Empirical Investigation of Chief Executive Officers' Personal Brand
Authors: Takács Ildikó , Takács Veronika , Kondor Anna
Published: August 2018

Leadership has been a topic of investigation in organizational studies for many years. Several researchers have investigated the ideal leader, and even more theories and models have been built around the concepts of leadership style, behavior, personality, performance, competences, skills and so on. However, studies of how these characteristics are combined as 'personal brands', and how they are perceived by the social environment are clearly lacking. The aim of the paper is therefore to identify the dimensions of CEOs' personal brand, in other words to investigate the aspects that apply to leaders’ social environment and to perceive and evaluate them. Using exploratory factor analysis on a Hungarian sample, three factors have been identified as the basis for CEOs' personal brand: competence, morality and humanity.

Published: August 2018

Improving the reliability and consistency of objective structured clinical examination (OSCE) raters’ marking poses a continual challenge in medical education. The purpose of this study was to evaluate an e-Learning training module for OSCE raters who participated in the assessment of third-year medical students at the University of Ottawa, Canada. The effects of online training and those of traditional in-person (face-to-face) orientation were compared. Of the 90 physicians recruited as raters for this OSCE, 60 consented to participate (67.7%) in the study in March 2017. Of the 60 participants, 55 rated students during the OSCE, while the remaining 5 were back-up raters. The number of raters in the online training group was 41, while that in the traditional in-person training group was 19. Of those with prior OSCE experience (n= 18) who participated in the online group, 13 (68%) reported that they preferred this format to the in-person orientation. The total average time needed to complete the online module was 15 minutes. Furthermore, 89% of the participants felt the module provided clarity in the rater training process. There was no significant difference in the number of missing ratings based on the type of orientation that raters received. Our study indicates that online OSCE rater training is comparable to traditional face-to-face orientation.
Popularising the Higgs boson: a corpus-assisted approach to reporting scientific discovery in online media
Authors: Incelli Ersilia
Published: August 2018

This study explores the scientific popularisation process and how science knowledge is recontextualised and rewritten in the transfer from one context or genre to another genre. It does this through a case study of the discovery of the Higgs boson, a new physics particle that is commonly known as the God Particle, and by focussing on the meta-discursive strategies that emerged from the texts after corpus-assisted analysis. Extensive use was made of exemplification and generalisation through analogies and metaphors, and through ideational content representing epistemic uncertainty in the newspaper discourse. Prominence is given to science popularisation in the British press, because online newspapers capture a wide non-expert public, the aim being to offer an analysis of how the discursive perspective of complex science news (particle physics) is conveyed to the general public, and can allow a systematic investigation into ‘how’ a scientific event is constructed and made newsworthy. Two corpora, consisting of texts from the scientific journal, Physics Letters B, and from online media blogs, were also compiled for contrastive purposes. In this way, prominent lexico-semantic textual properties are identified in the main corpus (containing newspapers) through standard corpus linguistic techniques, in particular through key semantic domain annotation, leading to more insight into how complex science is linguistically constructed and conveyed to a lay audience.

Oxidative stress and neuroinflammation play a key role in dopaminergic (DA) neuronal degeneration, which results in the hindrance of normal ongoing biological processes in the case of Parkinson’s disease. As shown in several studies, on 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) administration, different behavioral parameters have suggested motor impairment and damage of antioxidant defence. Thus, some specific biological molecules found in medicinal plants can be used to inhibit the DA neuronal degeneration through their antioxidant and anti-inflammatory activities. With this objective, we studied chlorogenic acid (CGA), a naturally occurring polyphenolic compound, for its antioxidant and anti-inflammatory properties in MPTP-intoxicated mice. We observed significant reoccurrence of motor coordination and antioxidant defence on CGA supplementation, which has been in contrast with MPTP-injected mice. Moreover, in the case of CGA-treated mice, the enhanced expression of tyrosine hydroxylase (TH) within the nigrostriatal region has supported its beneficial effect. The activation of glial cells and oxidative stress levels were also estimated using inducible nitric oxide synthase (iNOS) and glial fibrillary acidic protein (GFAP) immunoreactivity within substantia nigra (SN) and striatum of MPTP-injected mice. Administration of CGA has prevented the neuroinflammation in SN by regulating the nuclear factor-κB expression in the MPTP-induced group. The significant release of certain pro-inflammatory mediators such as tumor necrosis factor-α and interleukin (IL)-1β has also been inhibited by CGA with the enhanced expression of anti-inflammatory cytokine IL-10. Moreover, reduced GFAP staining within the nigrostriatal region has supported the fact that CGA has significantly helped in the attenuation of astrocyte activation. Hence, our study has shown that CGA supplementation shows its therapeutic ability by reducing the oxidative stress and neuroinflammation in MPTP-intoxicated mice.
Phosphorus monolayer doping (MLD) of silicon on insulator (SOI) substrates

Published: August 2018

This paper details the application of phosphorus monolayer doping of silicon on insulator substrates. There have been no previous publications dedicated to the topic of MLD on SOI, which allows for the impact of reduced substrate dimensions to be probed. The doping was done through functionalization of the substrates with chemically bound allyldiphenylphosphine dopant molecules. Following functionalization, the samples were capped and annealed to enable the diffusion of dopant atoms into the substrate and their activation. Electrical and material characterisation was carried out to determine the impact of MLD on surface quality and activation results produced by the process. MLD has proven to be highly applicable to SOI substrates producing doping levels in excess of 1 × 1019 cm−3 with minimal impact on surface quality. Hall effect data proved that reducing SOI dimensions from 66 to 13 nm lead to an increase in carrier concentration values due to the reduced volume available to the dopant for diffusion. Dopant trapping was found at both Si–SiO2 interfaces and will be problematic when attempting to reach doping levels achieved by rival techniques.
General Purpose Ray Tracing and Polarized Radiative Transfer in General Relativity
Authors: Pihajoki Pauli , Mannerkoski Matias , Nättilä Joonas , Johansson Peter H.
Published: August 2018

Ray tracing is a central tool for constructing mock observations of compact object emission and for comparing physical emission models with observations. We present Arcmancer, a publicly available general ray-tracing and tensor algebra library, written in C++ and providing a Python interface. Arcmancer supports Riemannian and semi-Riemannian spaces of any dimension and metric, and has novel features such as support for multiple simultaneous coordinate charts, embedded geometric shapes, local coordinate systems, and automatic parallel propagation. The Arcmancer interface is extensively documented and user friendly. While these capabilities make the library well suited for a large variety of problems in numerical geometry, the main focus of this paper is in general relativistic polarized radiative transfer. The accuracy of the code is demonstrated in several code tests and in a comparison with grtrans, an existing ray-tracing code. We then use the library in several scenarios as a way to showcase the wide applicability of the code. We study a thin variable-geometry accretion disk model and find that polarization carries information of the inner disk opening angle. Next, we study rotating neutron stars and determine that to obtain polarized light curves at better than a

level of accuracy, the rotation needs to be taken into account both in the spacetime metric and in the shape of the star. Finally, we investigate the observational signatures of an accreting black hole lensed by an orbiting black hole. We find that these systems exhibit a characteristic asymmetric twin-peak profile both in flux and polarization properties.
A Triple Origin for the Heavy and Low-spin Binary Black Holes Detected by LIGO/VIRGO
Authors: Rodriguez Carl L. , Antonini Fabio
Published: August 2018

We explore the masses, merger rates, eccentricities, and spins for field binary black holes (BHs) driven to merger by a third companion through the Lidov–Kozai mechanism. Using a population synthesis approach, we model the creation of stellar-mass BH triples across a range of different initial conditions and stellar metallicities. We find that the production of triple-mediated mergers is enhanced at low metallicities by a factor of ∼100 due to the lower BH natal kicks and reduced stellar mass loss. These triples naturally yield heavy binary BHs with near-zero effective spins, consistent with most of the mergers observed to date. This process produces a merger rate of between 2 and 25 Gpc−3 yr−1 in the local universe, suggesting that the Lidov–Kozai mechanism can potentially explain all of the low-spin, heavy BH mergers observed by Advanced LIGO/Virgo. Finally, we show that triples admit a unique eccentricity and spin distribution that will allow this model to be tested in the near future.

The imidogen radical is an important molecule of the chemistry of nitrogen in the interstellar medium and is thought to be a key intermediate in the gas-phase synthesis of ammonia. The full fine structure of the

rotational transition of

has been observed for the first time by pure rotational spectroscopy around 1 THz. The radical has been produced by means of low-pressure glow discharge of H2 and

-enriched nitrogen. A number of hyperfine components have been observed and accurately measured. The analysis of the data provided very precise spectroscopic constants, which include rotational, centrifugal distortion, electron spin–spin interaction, and electron spin–rotation terms in addition to the hyperfine parameters relative to the isotropic and anisotropic electron spin–nuclear spin interactions for 15N and H and to the nuclear spin–rotation for 15N. The efficiency of the discharge system allowed us to observe several components of the same rotational transition in the excited vibrational state v = 1, for which a set of spectroscopic constants has also been determined.
A Population of Bona Fide Intermediate-mass Black Holes Identified as Low-luminosity Active Galactic Nuclei

Nearly every massive galaxy harbors a supermassive black hole (SMBH) in its nucleus. SMBH masses are millions to billions of solar mass, and they correlate with properties of spheroids of their host galaxies. While the SMBH growth channels, mergers, and gas accretion are well established, their origin remains uncertain: they could have emerged either from massive “seeds” (105–106
M
⊙) formed by direct collapse of gas clouds in the early universe or from smaller (100 M
⊙) BHs, end products of first stars. The latter channel would leave behind numerous intermediate-mass BHs (IMBHs, 102–105
M
⊙). Although many IMBH candidates have been identified, none are accepted as definitive; thus, their very existence is still debated. Using data mining in wide-field sky surveys and applying dedicated analysis to archival and follow-up optical spectra, we identified a sample of 305 IMBH candidates having masses

We confirmed the AGN nature of 10 sources (including five previously known objects that validate our method) by detecting the X-ray emission from their accretion disks, thus defining the first bona fide sample of IMBHs in galactic nuclei. All IMBH host galaxies possess small bulges and sit on the low-mass extension of the

BST1047+1156: An Extremely Diffuse and Gas-rich Object in the Leo I Group
Authors: Mihos J. Christopher , Carr Christopher T. , Watkins Aaron E. , Oosterloo Tom , Harding Paul
Published: August 2018

We report the detection of diffuse starlight in an extragalactic H i cloud in the nearby Leo I galaxy group. We detect the source, BST1047+1156, in both broadband optical and the Galaxy Evolution Explorer (GALEX) ultraviolet (UV) light. Spanning ∼2 kpc in radius, it has a peak surface brightness of μ

B
 = 28.8 mag arcsec−2, making it the lowest surface brightness object ever detected via integrated light. Although the object is extremely gas rich, with a gas fraction of f

g
 = 0.99, its peak H i column density is well below levels where star formation is typically observed in galaxies. Nonetheless, BST1047+1156 shows evidence for young stellar populations: along with the detected UV emission, the object is extremely blue, with B − V = 0.14 ± 0.09. The object has two tidal tails and is found embedded within diffuse gas connecting the spiral galaxy M96 to the group’s extended H i Leo Ring. The nature of BST1047+1156 is unclear. It could be a disrupting tidal dwarf, recently spawned from star formation triggered in the Leo I group’s tidal debris. Alternatively, the object may have been a pre-existing galaxy—the most extreme example of a gas-rich field low surface brightness galaxy known to date—which had a recent burst of star formation triggered by encounters in the group environment.
Entomopathogenic fungi in Portuguese vineyards soils: suggesting a ‘Galleria-Tenebrio-bait method’ as bait-insects Galleria and Tenebrio significantly underestimate the respective recoveries of Metarhizium (robertsii) and Beauveria (bassiana)
Authors: Sharma Lav , Oliveira Irene , Torres Laura , Marques Guilhermina
Published: August 2018

Entomopathogenic fungi (EPF) are the natural enemies of insect-pests. However, EPF recoveries can be influenced by the soil habitat-type(s) incorporated and/or the bait-insect(s) used. Galleriamellonella (GM) as bait-insect, i.e. ‘Galleria-bait’, is arguably the most common methodology, which is sometimes used solely, to isolate EPF from soils. Insect baiting using Tenebriomolitor (TM) has also been employed occasionally. Here 183 soils were used to estimate the functional diversity of EPF in Portuguese Douro vineyards (cultivated habitat) and adjacent hedgerows (semi-natural habitat), using the TM bait method. Moreover, to study the effect of insect baiting on EPF recovery, 81 of these 183 soil samples were also tested for EPF occurrences using the GM bait method. Twelve species were found in 44.26% ± 3.67% of the total of 183 soils. Clonostachysroseaf.rosea was found in maximum soils (30.05% ± 3.38%), followed by Beauveriabassiana (12.57% ± 2.37%), Purpureocilliumlilacinum (9.29% ± 2.14%) and Metarhiziumrobertsii (6.01% ± 1.75%). Beauveriapseudobassiana (P < 0.001), C.roseaf.rosea (P = 0.006) and Cordycepscicadae (P=0.023) were isolated significantly more from hedgerows, highlighting their sensitivities towards agricultural disturbances. Beauveriabassiana (P = 0.038) and M.robertsii (P = 0.003) were isolated significantly more using GM and TM, respectively. Principal component analysis revealed that M.robertsii was associated both with TM baiting and cultivated habitats, however, B.bassiana was slightly linked with GM baiting only. Ecological profiles of B.bassiana and P.lilacinum were quite similar while M.robertsii and C.roseaf.rosea were relatively distant and distinct. To us, this is the first report on (a) C.cicadae isolation from Mediterranean soils, (b) Purpureocilliumlavendulum as an EPF worldwide; and (c) significant recoveries of M.robertsii using TM over GM. Overall, a ‘Galleria-Tenebrio-bait method’ is advocated to study the functional diversity of EPF in agroecosystems.

Sulcispora is typified by S.pleurospora. We collected a sulcispora-like taxon on leaves of Anthoxanthumodoratum L. in Italy and obtained single ascospore isolates. Combined ITS, LSU, SSU and tef1 sequence analyses suggested that Sulcispora is placed in the family Phaeosphaeriaceae and a newly collected Sulcispora species is introduced here as S.supratumida sp. nov. Detailed descriptions and illustrations are provided for Sulcisporasupratumida and it is compared with the type species, S.pleurospora.
ASSESSING THE IMPACT OF CONGRUENT AND INCONGRUENT STIMULUS IN STROOP TASK, USING EVENT-RELATED POTENTIALS (ERP) IN PATIENTS WITH DEPRESSION
Authors: Shahsavar Yeganeh , Ghoshuni Majid
Published: August 2018

The main goal of this event-related potentials (ERPs) study was to assess the effects of stimulations in Stroop task in brain activities of patients with different degrees of depression. Eighteen patients (10 males, with the mean age [Formula: see text]) were asked to fill out Beck’s depression questionnaire. Electroencephalographic (EEG) signals of subjects were recorded in three channels (Pz, Cz, and Fz) during Stroop test. This test entailed 360 stimulations, which included 120 congruent, 120 incongruent, and 120 neutral stimulations. To analyze the data, 18 time features in each type of stimulus were extracted from the ERP components and the optimal features were selected. The correlation between the subjects’ scores in Beck’s depression questionnaires and the extracted time features in each recording channel was calculated in order to select the best features. Total area, and peak-to-peak time window in the Cz channel in both the congruent and incongruent stimulus showed significant correlation with Beck scores, with [Formula: see text], [Formula: see text] and [Formula: see text], [Formula: see text], respectively. Consequently, given the correlation between time features and the subjects’ Beck scores with different degrees of depression, it can be interpreted that in case of growth in degrees of depression, stimulations involving congruent images would produce more challenging interferences for the patients compared to incongruent stimulations which can be more effective in diagnosing the level of disorder.
3D Finite Element Approach to Simulate the Contact Pressure between Two Deformable Cylinders. Application to a Spur Gear
Authors: Djemoui Mohamdi , Toufik Outtas
Published: August 2018

Knowing the stresses and pressures in the contact between two deformable solids is fundamental in order to optimize the strength and the lifetime of mechanical components such as bearings or gears. These constraints can be determined by the calculation (finite element method or Hertz theory) or by experimental methods such as photoelasticity. The objective of this study is to model and compute the stress field and contact pressure using 3D finite element software. The validation of obtained results is done by comparison with the classical results of the non linear Hertz theory between two deformable cylinders. An application to spur gears with a circle involute profile is done and also validate with the same Hertz theory.

Published: August 2018

The use of cheap and eco-friendly adsorbents studied as an alternative to activated carbon for removal of dyes from wastewater is the focus of this paper. Chitosan, which was produced from food industry waste (crab shells), was synthesized, characterized and utilized as adsorbent to remove cationic dye, basic blue, from wastewater by adsorption. Characteristics of the synthesized chitosan biosorbents was established using scanning electron microscope (SEM), and Fourier Transform Infra-Red (FTIR) spectroscopy. Experiments were conducted in batch forms to investigate the effects of contact time, initial dye concentration and adsorbent dosage. Kinetic and isotherm analysis of the adsorption process were also carried out. The results obtained revealed that removal efficiency of the chitosan was increased as the contact time and chitosan biosorbent dose were increased, but a decrease with increasing initial concentration of basic dye was observed. The pseudo-second order reaction model was found to describe the biosorption process best, with chemisorption as the rate limiting step. The maximum colour removal efficiencies of chitosan at dosage of 4 g for time duration of 90 min was found to be 91.88% of the dye from a solution of 80 ppm. The pseudo-second order kinetic model was also seen to agree very well with the dynamic behaviour of the adsorption of basic blue on chitosan under different contact time, initial dye concentrations and adsorbent dosages. The dynamic behaviour of adsorption of basic blue onto chitosan has the model fitness in the following order: pseudo-second order > Elovich model > pseudo-first order. The Elovich equation was found to be the best fit equilibrium isotherm for the sorption of basic blue onto chitosan based on linearized correlation coefficient. Moreover, the equilibrium isotherm has its model fitness to be in the order of Elovich model > Langmuir model > Freundlich model.

Published: August 2018

In this work, the control of the mole fraction of a fuel additive being produced in a reactive distillation column has been carried out using proportional-integral-derivative (PID) control. The fuel additive considered in this case was isopropyl alcohol, which was produced from the reaction between propylene and water. To accomplish the work, a ChemCAD model of the process was first developed and simulated to convergence before it was converted to dynamic type from which the dynamic responses of the system were generated and used, with the aid of MATLAB, to develop a transfer function model having the reboiler duty, the reflux ratio and the temperature of the bottom product as the input, the disturbance and the output variables of the process, respectively. The obtained transfer function model was used to develop the open-loop and the closed-loop Simulink models of the process that were also simulated. The closed-loop simulation was carried out with the objective of achieving a fuel additive product with a mole fraction of 0.97, and this was done using a PID controller that was applied inferentially via the product temperature. The results obtained showed that the control of the fuel additive mole fraction could be achieved inferentially, with PID controller tuned with Cohen-Coon and Simulink approaches, using product temperature.

In global manufacturing system, reduction of weight for automobile components is the main concern in automotive manufacturing industries. This research work focuses to improve the high strength ratio by reducing the weight of steel plate composite cart spring. The objective is to investigate the total load carrying capacity, stiffness and weight savings of composite cart spring and compare with that of steel cart spring at specified loading and over loading conditions. The examination was done for the cart spring made up of steel and composite materials of epoxy resin, e-glass fiber and nano particles. The specimens were fabricated by laminated composite with two dissimilar wagering progressions of resin with clay and nanoparticles. The constant thickness and width for cross section was maintained on the moulding techniques. The proposed design of multi level composite cart spring was modeled through PTC developed software of Pro Engineer and imported in simulation and 3-D design software of ANSYS R16.0. The existing measurements of a multi level cart spring was considered for modeling and investigation of a proposed laminated composite cart spring under same loading conditions. From the results it was found that, about 80% of the weight was reduced in the proposed laminated composite cart spring by replacing steel plates with composite materials.

Published: August 2018

An experimental investigation was carried out of coal-water fuel (CWF) drops ignition and combustion. CWF examples were produced by using of coal of different metamorphic stages, including brown coal, flame coal, and gas coal. The processes of combustion and ignition of CWF took place in the air. Time-temperature dependences of ignition and combustion processes were obtained; basic stages of CWF combustion were established and investigated; combustion completeness was defined and ash residue structure and properties were investigated during the experimental research. Influence of the working medium temperature on the time duration of each burning stage was defined. Generalization of results was carried out. It is shown, that duration of the volatiles combustion stage doesn’t depend on the medium temperature and stay constant for each of coal grade. Time interval before CWF ignition can be described with power-type dependence, which is identical for all metamorphic stages of coal. The maximum temperature of CWF combustion grows linearly in respect to the medium temperature in the oven.

Authors: Mokhtari Abderrahmane , Belkheiri Mohammed
Published: August 2018

This paper addresses the problem of fault detection and isolation (FDI) in wind turbine benchmark model using data driven and multi-class support vector machine (SVM) approach. Since, the fault detection is fundamental for any active system, isolation is similarly vital, and identification is decisive for fault reconfiguration as well as maintenance addition to monitoring purposes. The need for man-made dynamic system to work automatically when sensor, actuator, or system faults occur was constantly developed in order to increase reliability and decrease unavailability and maintenance costs. The key step of our approach based on extraction of mean features from sensors measurements by applying the statistical methods such as moving standard deviation and the exponential weighted moving average (EWMA). The fault detection step is invoked later based on the multi-class SVM classifier that decides the presence or not of the fault. Another important contribution of this paper is the simulation of combined sensor and actuator faults simultaneously for the first time in wind turbine benchmark model. The FDI performances are illustrated through simulation study for seven different scenario tests. The results demonstrate clearly the effectiveness of statistical and SVM approach to detect and isolate single, multiple sensor and actuator faults and outperforms many results reported in the literature for solving this problem.
