Published: February 2018

Photosensivity prediction of several azopyridine ruthenium complexes by DFT and TDDFT methods was performed. g-RuX2 (Azpy) 2 and d-RuX2(Azpy)2 where X stands for F, Cl, Br and I were studied todetermine their activities when halide atoms shift. So, frontier orbital, NBO, NLMO and MLCT transitions as well as an excited lifetime of those complexes was determined. The main difference between them stems from both the electronegativity of the halide atoms and the structure of each complex. Hence, the rank of halide's electronegativity that is as followscp(F)>cp (Cl)>cp (Br)>cp (I) has been discovered to influence all the reactivity of the complexes regardless their structure. Herein, the comparison with the gap energy shows that the most reactive complexes are those with fluorine atom. Especially, d-RuF2(Azpy)2 was admitted to be the most active isomer. Moreover, NBO calculation discloses that the complex becomes less ionic when the electronegativity decreases from F to I atoms. Furthermore, the calculation of NLMO orbitals shows that the bonding Ru-X are very strong. However, this strength decreases also from F to I and the nature of the bonding move from ionic to metallic. Moreover, the bonding from Npy and N2 with Ru are known to be the same confirming the bidentate state of Azpy ligand. Regarding the electronic prediction, the eight complexes are surely assumed to display MLCT transitions that originate the photosensitivity. However, the complex that requires the least energy remains d-RuF2(Azpy)2. This result was also determined by analyzing the excited lifetime that is the ability for a complex to longer linger in the cationic state. At last, we found out that with iodine atoms, the azopyridine ruthenium complex cannot behave as photosensitize dye insofar as I atom hides the main orbitals from Ru regardless the symmetry.

Authors: Alamsyah Derry
Published: February 2018

The car recognition is part of the field of traffic surveillance on the image. In general, the car recognition using the form-based feature as a unique feature. Another feature in object recognition is the frequency feature. One feature of frequency is the Fourier feature, this feature is obtained by using Fast Fourier Transform (FFT) method. The object recognition can be done by determining the maximum value of likelihood and classifying it with Maximum Likelihood Classification (MLC). The use of FFT and MLC in the car object recognition has never been used. The results of both are in a good accuracy that is 76%.

Authors: Handoyo Antonius Erick , Setiadi De Rosal Ignatius Moses , Rachmawanto Eko Hari , Sari Christy Atika , Susanto Ajib
Published: February 2018

This study proposed a combination of steganography and cryptography techniques using LSB and RSA methods. RSA is a popular cryptographic technique that can be applied to digital imagery. Digital image pixel values range from 0 to 255, making the keys used in RSA limited enough and less secure. So in this study, it is proposed to convert pixel image value to 16 bits so that the key used can be more varied. Experimental results proved that there was a steady increase in security and imperceptibility. This was shown by the results of PSNR 57.2258dB and MSE 0.1232dB. This method was also resistant to salt and pepper attacks.

Authors: Tinaliah Tinaliah , Elizabeth Triana
Published: February 2018

Various methods are applied in the application of plagiarism detection to help check the similarity of a document. Jaro-Winkler Distance can measure the distance between two strings. However, this method basically depends on the position of the word. Latent Semantic Analysis emphasizes the words contained in the document regardless of its linguistic character. This study compares the results of plagiarism detection using the Jaro-Winkler Distance and the Latent Semantic Analysis method. From comparing results of  Jaro-Winkler Distance method and Latent Semantic Analysis method, Jaro-Winkler Distance method is better than Latent Semantic Analysis method if using the same test data. Jaro-Winkler Distance method will give plagiarism result 100% and Latent Semantic Analysis method will give plagiarism result 97,14%.
The rise and fall (?) of the digital natives
Authors: Judd Terry
Published: February 2018

Building on the earlier net generation and millennials concepts, Prensky popularised the notion of a generation of “digital native” students through his 2001 two-part series “Digital natives, digital immigrants”. Although his ideas about how students perceive and utilise technology resonated with many educators, they lacked supporting evidence. Subsequent investigations, which informed the so-called “digital natives debate”, produced largely contrary evidence and dissenting views. As dissemination and acceptance of this evidence grew, interest in the idea of students as digital natives should have waned. However, a detailed analysis of general and academic search data and of articles published in leading educational technology journals (between 1998 and 2017) suggests that this interest remains strong. Although references to digital natives and the related terms net generation and millennials in educational technology journals has declined somewhat (having peaked in 2011), public and general academic search interest in these terms – and presumably the ideas that underpin them – continues to grow. These trends are discussed from an historical perspective, considering how our acceptance (or rejection) of the digital natives concept has developed, and the potential past, present and future impact of this on technology adoption and implementation practices within our universities.
Characterization of Self-Weight Consolidation of Fine-Grained Mine Tailings Using Moisture Sensors
Authors: Saleh-Mbemba Faustin , Aubertin Michel
Published: February 2018

This paper presents an experimental procedure and testing results on the consolidation of saturated tailings based on measurements made with moisture sensors. A special calibration procedure has been developed for precise volumetric water content measurements to reflect the progressive change of density and void ratio in the loose tailings. The moisture sensors’ readings are used to evaluate key parameters during self-weigh consolidation, which allow an assessment of the settlement’s rate and magnitude. The results indicate that the proposed technique can be useful to assess the tailings slurry characteristics, which significantly evolve during self-weight consolidation. The experimentally determined parameters are in the range provided by other investigations conducted on the same materials. It is also shown that pore-water pressures deduced from the volumetric water content measurements during the laboratory tests correlate well with the profiles obtained from the one-dimensional consolidation theory.
Wear Resistance of Four Rocks Using Rotary Abrasion Test in Dry and Wet Conditions
Authors: Lee Taegeon , Lee Seung Oh , Ryu Dong-Woo , Youn Heejung
Published: February 2018

This article investigates the wear resistance of four rock types using the rotary abrasion test. The tested rocks include argillaceous rocks (mudstone and shale) and igneous rocks (granite and andesite). The wear volume of the rock specimen was measured with various wear time, normal loads, specimen lengths, and water conditions. It was found that the wear volume of rock specimen linearly increased with wear time and normal load per unit length. The Wear Volume Index was proposed to represent the wear volume of the rocks, which was measured to be the greatest for mudstone, followed by shale, granite, and andesite for both wet and dry conditions. The presence of water significantly affects the Wear Volume Index of argillaceous rocks, which increased by 60 % for mudstone and 25 % for shale. On the other hand, the effect of water was found to be insignificant for igneous rocks such as granite and andesite.
Early Age Thermal Measurements of Soil-Cement Mixtures for Quality Control during Paving
Authors: Sullivan W. Griffin , Howard Isaac L. , Cost Tim , Shannon Jay
Published: February 2018

Cementitiously stabilized soil (i.e., soil-cement) is popular among some state departments of transportation (DOTs) for subbase and base pavement layers, particularly, states with limited supplies of quality aggregates. When constructed properly, soil-cement has proven to be a well-performing and economically beneficial product for multiple DOTs; however, there is still a growing need to better characterize soil-cement properties in the laboratory and especially during construction. This need could partly be met with thermal profile measurements of hydrating soil-cement mixtures. The overall purpose of this article is to investigate the potential use of thermal measurements as a quality control tool for compacted soil-cement mixtures used in pavement layers. A compaction device, referred to as the Plastic Mold (PM) device, was central to the approach presented in this article to perform thermal measurement and unconfined compressive strength (UCS) testing on the same specimen. Based on data presented in this article, thermal profile measurements of soil-cement mixtures are feasible and have some merit as a quality control tool. Variability analysis under laboratory conditions showed measured thermal profile results were less variable or equally as variable as UCS measurements. Under field conditions, thermal profile testing was observed to be sensitive to initial material temperature, thermal device insulation, and surrounding environment temperatures. Implementation of thermal measurements into soil-cement quality control seems to be best suited as supporting information only for cases in which UCS measured by the PM device needs more explanation.

MANAGEMENT OF ENDOCRINE DISEASE Hyperandrogenic states in women: pitfalls in laboratory diagnosis
Authors: Pugeat Michel , Plotton Ingrid , de la Perrière Aude Brac , Raverot Gérald , Déchaud Henri , Raverot Véronique
Published: February 2018

Measuring total testosterone level is the first-line approach in assessing androgen excess in women. The main pitfalls in measuring testosterone relate to its low concentration and to the structural similarity between circulating androgens and testosterone, requiring accurate techniques with high specificity and sensitivity. These goals can be achieved by immunoassay using a specific anti-testosterone monoclonal antibody, ideally after an extraction step. Liquid chromatography coupled to tandem mass spectrometry (LC–MS/MS) will be commonly used for measuring testosterone, providing optimal accuracy with a low limit of detection. Yet, the pitfalls of these two techniques are well identified and must be recognized and systematically addressed. In general, laboratories using direct testosterone immunoassay and mass spectrometry need to operate within a quality framework and be actively engaged in external quality control processes and standardization, so as to ensure appropriate interpretation irrespective of the particular laboratory. Circulating testosterone is strongly bound to sex-hormone-binding globulin (SHBG), and SHBG levels are typically low in overweight hyperandrogenic patients. Thus, low SHBG may decrease circulating testosterone to normal values, which will mask androgen excess status. One way to avoid this pitfall, awaiting direct free testosterone assays that are yet to be developed, is to measure SHBG and calculate free testosterone. A few other pitfalls will be discussed in this review, including those of adrenal androgen exploration, with the aim of helping clinicians to better handle laboratory investigation of androgen excess disorders in women.

AbstractThe ‘dilemmas’ between multilingualism in theory and English as a lingua franca in practice concern the post-Bologna European higher education as a whole. The article presents the case of Slovenia by furthering the analysis of similar quandaries present in the Slovenian (higher education) language policy. The state of affairs is addressed by acknowledging the status of Slovenian as the official language of the Republic of Slovenia, as well as the need for a greater inclusion of foreign students and teachers and for further enhancement of the quality of higher education. The results of surveys conducted among the most important stakeholders in the Slovenian higher education in October 2012, with the aim of researching the viewpoints on the use of languages of instruction in higher education, are presented. The results were analysed with a view to the expressed standpoint on language use in higher education, which led to the formation of three opinion groups within the sample of students and university teachers of the University of Ljubljana. Based on the analysis of accessible sources, discussions, opinions, surveys and interviews some recommendations on the regulation of language use in higher education in Slovenia are provided.Key words: higher education; internationalisation; language policy; Slovenian university policy.---Sažetak„Nedoumice“ između višejezičnosti u teoriji i engleskoga kao lingue france u praksi tiču se poslijebolonjskoga europskoga visokog obrazovanja u cjelini.

Published: February 2018

AbstractThis paper analyzes the learning outcomes of study programs and courses at the Faculty of Humanities and Social Sciences, University of Zagreb, and associates them with levels of Bloom's taxonomy in order to determine their relationships. The analysis showed statistically significant differences in the levels of learning outcomes between studies and their courses. The outcomes of study programs place more emphasis on higher levels of cognitive, affective and psychomotor domains. It was determined that there is a slight difference between the courses at the undergraduate and graduate levels of study, which is in accordance with expectations as the learning outcomes at the undergraduate level include lower levels of cognitive and affective domains. The analysis of compulsory and elective courses showed that elective courses place more emphasis on the cognitive domain, whereas compulsory courses place more emphasis on the affective domain.Key words: Bloom's taxonomy; comparison of learning outcomes; levels of learning outcomes.---SažetakU radu se analiziraju ishodi učenja studijskih programa i predmeta na Filozofskom fakultetu Sveučilišta u Zagrebu te povezuju s razinama Bloomove taksonomije, kako bi se utvrdili njihovi međusobni odnosi.

Abstract The aim of this research is to determine the effect of the Flipped Classroom Approach Based on the 5E Learning Cycle Model called 5ELFA on student achievement in a physics course. It also aims to determine the students’ opinions regarding this approach. This study, conducted using a mixed methods approach, involved 94 engineering students enrolled in the Physics 101 course. In the research, in which the pretest-posttest control group design was used, students were randomly assigned to experimental and control groups. While the students in the experimental group took the physics course in the Flipped Classroom Approach Based on the 5E Learning Cycle Model for 10 weeks, only the 5E learning model was used in the control group. The quantitative data were collected from a physics achievement test and the qualitative data were collected from semi-structured interviews. The results indicated that the physics achievement post-test scores of the experimental group were significantly higher than those of the control group. Interviews with experimental group volunteers revealed that the majority of students held a positive opinion of the flipped classroom approach and they believed that it had a positive impact on the physics course. Key words: 5E learning model; flipped classroom; higher education; physics education. ---SažetakCilj ovog istraživanje bio je odrediti utjecaj nastavnog pristupa obrnute učionice koji se temelji na 5E modelu ciklusa učenja, nazvan 5ELFA, na postignuća studenata u kolegiju Fizike.

Medical malpractice, which is defined as “patients’ harm resulting from healthcare professionals’ improper and unethical attitude or insufficient and sloppy practice”, is strictly limited to healthcare professionals’ errors in practice. However, it should include system error analysis.  In this article, a missed case of system error resulted in death is presented to remind the concept to Forensic Medicine experts and review the literature.
A 20-year-old male who underwent renal transplantation from a live donor, underwent graft nephrectomy due to acute accelerated rejection. The patient with cardiac overload findings in the postoperative period, collapsed while the patient was being sent to a special center for urgent dialysis due to lack of functional dialysis unit. In the transfer ambulance, there was no oxygen source and the patient was unable to actively ventilate. The patient died while under intensive care. In our evaluation, system error has been detected and the administration was held responsible.
The experts who are asked about the medical malpractice have to take the basic concept of "medical error" as a basis for considering the mistakes of medical applications not only from the point of view of health professionals.

Aptamers, also known as artificial antibodies, are capture elements that are attached to target molecules of different sizes with high affinity, and selectivity. They are successfully used in many different sensor applications over the last 30 years. Aptamers have unique advantages such as being able to be produced in a laboratory environment in contrast to antibodies produced via immunoactivity, easy to amplify and purify and to be produced in an infinite configuration. In addition to the military, environmental, food safety and medical applications, the use of aptamers in forensic sciences is inevitable. In this article, examples of aptamers and their applications in forensic sciences are given. Due to a large number of applications in the literature, latent fingerprint visualization and cocaine detection cases are given as examples of aptamer applications in forensic science.

Introduction: Forensic postmortem examination is an issue that physicians have difficulties and have legal problems. It would be appropriate to add applications that are more memorable and appealing to the students for forensic postmortem examination education in medical faculties. This study was conducted in order to measure the results of the "forensic postmortem examination education on the model in the context of a structured scenario", which may be a good model for the application of interactive methods, at the Faculty of Medicine of Pamukkale University.
Material and Methods: Eighty-eight 5th term students who were in forensic medicine training and 52 6th term students who were in public health training participated in the study. The knowledge and skill levels before and after the training and the opinions and recommendations about the education were evaluated and compared with standard forms.
Results: When pre-test and post-test answers are evaluated; the positive difference between the pre-test and post-test answers of all the students was statistically significant in which the level of knowledge was assessed, except for the first question’s answer in 5th term students. When the forms of opinions and recommendations are examined; it was understood that the vast majority of the students had confidence in themselves in the practice of postmortem examination and the decision of the autopsy which they would encounter in the future, all students who gave written feedback reported that the education was fruitful and useful and that they were pleased with this education.
Conclusion: Our practice has been a successful practice in acquiring the skills of forensic postmortem examination which is in the pre-graduate medical education core curriculum. This practice can also set an example for other medical schools in the teaching of forensic postmortem examination.

Published: February 2018

The present work will introduce a Finite State Machine (FSM) that processes any Collatz Sequence; further, we will endeavor to investigate its behavior in relationship to transformations of a special infinite input. Moreover, we will prove that the machine’s word transformation is equivalent to the standard Collatz number transformation and then discuss the possibilities for utilizing this approach for solving similar problems. The benefit of this approach is that the investigation of the word transformation performed by the Finite State Machine is less complicated than the traditional number-theoretical transformation.

Ezra Pound’s Shi-Shu: Rats is read Foucauldianly to instantiate an interaction between Confucianism and Western schools of thought in response to the problem of evil. There is a review of Leibniz’s theodicy to clear up confusion, and also to pave the way for a succession of readings of a number of philosophers like Hume and James — foregrounding epistemic inclination of poets like Pope, Wordsworth and Burns. ‘Accidentality’ and ‘essentiality’ are key philosophic terms, without which this problem cannot hold its logical structure, especially in terms of an answer. Epistemo-political ‘docility’ and literal ‘decency’ are employed together for the first time to be reintroducing ancient relationship between cruel politicians and carceral system. Utopia is taken as a mere dream so that ‘the problem’ would tend to keep its identity. What is new in this paper is a ‘gaze’-wise trace of mice in literature supporting the problem of evil in philosophy, based on an actual political background, within a broad sociological realm.

Background: The purpose of this study was to describe the characteristics of respiratory pathologies during pregnancy and postpartum.Methods: This was a case-control study over a 7-year period from January 2008 to December 2014 at CHU de COCODY. We compiled 86 cases of the PPH department hospitalized patients for pulmonary disease during pregnancy and for postpartum up to 42 days after delivery. The control samples were represented by those hospitalized in Obstetrics for a non-respiratory general condition during the same gravido puerperal period.Results: The age group of 20-29 years was the most affected in both groups with extremes ranging from 16 to 40 years (p=0.827). Respiratory pathology was common among housewives or unemployed women (p=0,001). Pauciparous and multiparous were the most affected (p=0.020). They had a medical history in 55.8% of cases versus 22.8% in controls (p=0.001). Positive HIV serology was also found (p=0.001) and was most often passive tobacco related (p=0.015). Respiratory pathology was progressive in 72.9% in cases vs 8.9% (p=0.001) with dyspnoea as the main sign (58%). Tuberculosis (29.70%) was the most common respiratory disease. Maternal complications accounted for 48.1% of PPH vs 25.6% (p=0.001) with maternal mortality of 11.6% (p = 0.001). As for foetal prognosis, 25.6% of foetal complications were noted in patients admitted to PPH versus 48.1% (p = 0.001).Conclusions: Respiratory disease during the gravido puerperal period is severe with significant maternal repercussion.

Background: The study was aimed to assess the difference in IUI outcome depending on the interval between hCG trigger and IUI and sperm preparation and IUI.Methods: The study was conducted in the Department of Obstetrics and Gynecology in Infertility unit at King George’s Medical University, Lucknow from January-December 2016. All the women eligible for IUI were included in the study. Once the follicle attained size of 17-18 mm, IUI was planned 36-48 hours after Inj. hCG 10,000 IU im. Semen processing was done in laboratory and time noted between sperm preparation and IUI. Outcome was confirmation of pregnancy by urine test. Cases were women in whom IUI was done 36-40 hours after hCG as against controls (>40 hours). Interval between sperm preparation and IUI was <30 minutes in cases and ≥30 minutes in controls.Results: A total of 624 cycles were included in the study. Clomiphene was used in 582/624 cycles (93.3%) gonadotropins used in 42/624 cycles (2.7%). There was a total of 23 conceptions in study (3.7%). Of these 8/98 (8.2%) were seen when the interval between ovulation trigger and IUI was 36-40 hours and 15/526 in cycles (2.9%) when the interval was more than 40 hours (p=0.023; OR-3.028 95% CI -1.247-7.352). Of a total of 23 conceptions in the study, 18/324 conceptions were seen when IUI was done within 30 minutes of sperm preparation as compared to 5/300 when interval was more than 30 minutes (p=0.01).Conclusions: IUI with ovarian stimulation is a simple and effective procedure and its outcome can be maximized keeping in consideration the availability of gametes. IUI performed within 36-40 hours of hCG trigger and within 30 minutes of sperm preparation can increase conception rates.
Electrochemical oxidation pathway of the anti-cancer agent dasatinib using disposable pencil graphite electrode and its adsorptive stripping voltammetric determination in biological samples
Authors: ESKİKÖY BAYRAKTEPE Dilek , POLAT Kamran , YAZAN Zehra
Published: February 2018

The present study describes the
use of pencil graphite electrode (PGE) for the investigation of
electro-oxidation mechanism and voltammetric stripping determination of
dasatinib (DST) in Britton-Robinson buffer solution (BR). Relating to cyclic
voltammetric studies, an irreversible oxidation signal was obtained at about
1.0 V. The oxidation electrode process is adsorption-controlled and
pH-dependent. For quantitative determination of DST, square wave adsorptive
stripping voltammetry (AdsSWV) was employed in BR of pH 3.0. The oxidation peak
current varies linearly with the DST concentration in the range of 0.0092 – 1.0
µM. Dedection (LOD)
and quantification (LOQ) values are founded as 0.0028 µM and 0.0092 µM, respectively. The developed
AdsSWV method based on disposible and cheap PGE was applied successfuly to the real
urine samples and the recovery results are given in the range of 97.94% to
100.82%.

Authors: Anaya Vera Esther , Polanco Lazo Rodrigo
Published: February 2018

El presente trabajo estudia el rol que actualmente tiene el Tribunal de Justicia de la Comunidad Andina (CAN) en la solución de controversias entre inversionistas extranjeros y Estados receptores de dicha inversión. Asimismo, efectúa un análisis prospectivo del rol que podría tener en la resolución de dichos conflictos, teniendo en cuenta que algunos países de la región han decidido excluirse del principal foro de solución de estas controversias –el Centro Internacional de Arreglo de Diferencias Relativas a Inversiones (CIADI)– y que los Estados miembros de la Unión de Naciones Suramericanas (UNASUR) se encuentran estudiando la generación de una alternativa regional para la solución de estas disputas.
O Brasil e a proteção jurídica dos investimentos estrangeiros: da negociação de novos acordos à reflexão sobre o seu cumprimento a partir da arbitragem de investimentos
Authors: Rocha Gabriel Vivian Daniele , Fontoura Costa José Augusto
Published: February 2018

A arbitragem de investimento cresceu consideravelmente na América Latina durante a década de 1990, contudo, Brasil permanece até os dias de hoje ao largo desse sistema, mesmo diante de sua importância no hodierno cenário jurídico internacional. Ao adquirir também a posição de investidor, faz-se necessário que o Brasil retome o debate quanto à utilização do Direito Internacional dos Investimentos, para que possa conferir proteção aos seus nacionais e, também, participar da reconstrução desse ramo do Direito.
Entre orden y sistema ALADI, CAN, MERCOSUR y OSD: las consecuencias de la cooperación jurídica en el futuro de las integraciones comerciales regionales
Authors: Thiel Méryl
Published: February 2018

La diversidad política e histórica de los estados miembros de la ALADI, CAN y del MERCOSUR hace que el regionalismo latinoamericano vaya cambiando de forma y oscile entre la simple voluntad de cooperar y la ambición de elaborar un derecho regional uniforme. En lo comercial, las diferencias entre sus ambiciones respectivas chocan con la necesidad de respetar las normas de la OMC. Resultan a veces situaciones de conflicto, y a veces situaciones de complementariedad entre los órganos jurídicos de estas organizaciones. Este artículo se propone destacar esta oposición, para subrayar la existencia de una tercera vía entre cooperación e integración, entre orden y sistema.
Discussing the tension between states’ right to regulate and foreign investment protection in recent Colombian cases
Authors: Guinard Hernández David Mauricio
Published: February 2018

Investment Agreements are instruments used by states to attract foreign ventures within their borders and obtain favourable treatment to local investors in counterpart nations. States usually compromise a certain degree of sovereignty in this kind of agreements through the inclusion of legal stability agreements, stabilisation clauses, compensation for expropriation, and fair & equitable treatment provisions. Within the context of this kind of agreements, the legitimate exercise of regulatory powers by states enters in conflict with the protection of foreign investors property rights when it comes to sensitive areas that have a high impact in the public interest, politics and public perception (such as human rights, health, safety, labour standards and the environment). Based on the discussion of two recent paramount cases that involve regulatory actions of the Colombian state and property rights of foreign investors (pharmaceutical ip rights vs public health interests in the first case, consolidated mining titles vs environmental protection in the second case), we identify and criticize the difficulties of defining if a governmental regulatory action is legitimate and non-compensable or if it is subject to compensation as an indirect expropriation, and the high dependence of this matter on the interpretation of arbitral tribunals.
El “Pico y Placa” en Bogotá: ¿peor el remedio que la enfermedad?
Authors: Camargo Díaz Emma J.
Published: February 2018

El presente trabajo pretende hacer un análisis de la medida de restricción vehicular conocida como “pico y placa”, implementada en la ciudad de Bogotá D.C. con el objetivo de solucionar el problema de la congestión. Desde la perspectiva del Análisis Económico del Derecho y la teoría de juegos, se demuestra la ineficiencia de esa medida, que ha dejado a la ciudad en una situación en la cual no solo no se cumple con el objetivo de la norma, sino que, por el contrario, se genera un aumento del parque automotor que genera, incluso, más congestión y contaminación. El artículo finaliza presentando algunas herramientas económicas alternativas para solucionar el problema de la congestión en la ciudad, como (i) los peajes urbanos, (ii) la venta de permisos de circulación y (iii) la congelación del parque automotor, con mercado de placas de tránsito y sistema de chatarrización.
Condicionador Unificado de Qualidade de Energia Monofásico–Trifásico Aplicado em Redes de Distribuição de Energia Elétrica MRT
Authors: Silva Sérgio Augusto Oliveira da , Negrão Fernando Alves
Published: February 2018

Este trabalho apresenta a validação experimental de um sistema local de distribuição de energia trifásico a quatro fios (3P4W), utilizando uma topologia de condicionador de qualidade de energia unificado (UPQC) monofásica- trifásica denominada UPQC-Mono-Tri. A topologia é indicada para aplicações em áreas rurais ou remotas, nas quais, por razões econômicas, apenas sistemas de distribuição de energia monofásicos com retorno por terra são acessíveis ao consumidor. Uma vez que o uso de cargas trifásicas é crescente nestas áreas, o acesso a um sistema de distribuição trifásico se torna preponderante. Adotando uma estratégia de compensação dual, o UPQC-Mono- Tri proposto é capaz de drenar da rede elétrica monofásica uma corrente senoidal e em fase com a tensão, obtendo-se assim um elevado fator de potência. Além disso, o sistema também é capaz de suprimir harmônicos de tensão da rede, assim como compensar outros distúrbios como, por exemplo, afundamentos de tensão. Desse modo, um sistema 3P4W com tensões reguladas, balanceadas e senoidais com baixos conteúdos harmônicos é disponibilizado para as cargas monofásicas e trifásicas. Resultados experimentais são apresentados com o objetivo de validar a proposta, bem como avaliar os desempenhos estáticos e dinâmicos da topologia proposta.
Estratégias de Energização e Desenergização de um Compensador Estático Síncrono para Distribuição
Authors: Duarte Samuel N. , Fogli Gabriel A. , Almeida Pedro M. de , Barbosa Pedro G.
Published: February 2018

Este trabalho propõe dois controladores para energizar e desenergizar compensadores estáticos síncronos destinados a serem conectados nas redes de distribuição. O primeiro circuito é baseado em um retificador semi–controlado enquanto o segundo controlador é baseado em um circuito gradador. Os dois controladores propostos são facilmente adaptados a estrutura do compensador estático sem a necessidade de realizar alterações topológicas no conversor. Um modelo matemático é usado para derivar as relações matemáticas usadas para controlar as correntes de energização e de desenergização. Aproximações lineares por partes foram usadas para reduzir o esforço computacional dos algoritmos de controle desenvolvidos. Resultados de simulação e experimentais são apresentados para validar a metodologia proposta.
