A morfometria de uma bacia hidrográfica pode fornecer subsídios para o adequado planejamento e gestão de recursos hídricos em nível de bacia hidrográfica. Neste sentido, objetivou-se com este estudo realizar a análise morfométrica de uma sub-bacia hidrográfica do Rio Piracicaba (MG), utilizando o Sistema de Informações Geográficas. A área de drenagem e o perímetro da bacia estudada foram estimados em 1.138,80 km² e 205,16 km, respectivamente. A análise dos parâmetros de forma, do sistema de drenagem e do relevo da bacia aponta, respectivamente, baixa susceptibilidade a ocorrência de enchentes, baixa capacidade de drenagem, potencial de degradação por erosão do solo e ocorrência de precipitações bem distribuídas e regulares. O uso de dados advindos de imageamento por satélites integrado às técnicas de geoprocessamento comprovou elevada eficiência como ferramenta para ações atreladas ao planejamento e gestão dos recursos hídricos, sendo ainda eficiente na redução de custos, tempo e padronização científica na execução de experimentos.

Este trabalho objetivou avaliar a qualidade do composto final proveniente de diferentes fontes de carbono e nitrogênio na compostagem de resíduos orgânicos resultantes das refeições do Restaurante Universitário (RU) da Universidade Federal de Lavras. Foram realizados quatro tipos de tratamento (T1 - capim e resíduo do RU; T2 - capim, resíduo do RU e lodo de esgoto; T3 - serragem/maravalha e resíduo do RU; e T4 - serragem/maravalha, resíduo do RU e lodo de esgoto). Para cada tratamento foram feitas duas repetições, cada pilha de compostagem teve a forma cônica com aproximadamente 1,30 metro de altura por 2 metros de base. O experimento foi conduzido com uma umidade de 40%. Após 120 dias em campo, o pH final dos tratamentos foram 8,6; 7,7; 6;7 e 6,8 respectivamente para os tratamentos T1, T2, T3 e T4. Por sua vez, os tratamentos T1 e T2 obtiveram uma relação C/N melhor que os tratamentos T3 e T4, onde os valores respectivos foram de 13,1 e 11,4 para T1 e T2, e 32,2 e 48,4 para T3 e T4. Entre os micronutrientes e metais pesados encontrados no composto final, o zinco e o cobre apresentaram valores abaixo das normativas sugeridas pelo Ministério da Agricultura, Pecuária e Abastecimento (MAPA) e pelo Conselho Nacional do Meio Ambiente (Conama) para todos os tratamentos. Conclui-se que os compostos produzidos a partir de resíduos de restaurante e de lodo de esgoto T1 e T2 atenderam as normas avaliadas e podem ser aplicados no solo como adubo orgânico.

Published: May 2018

Estudos sobre a faixa de conteúdo de água disponível para as plantas são geralmente baseados em análises da curva de retenção de água no solo (CRA).A obtenção da CRA envolve determinação em laboratório, por meio de procedimentos morosos e dispendiosos, motivando a avaliação de métodos alternativos. Objetivou-se neste trabalho avaliar o desempenho de funções de pedotransferência para a obtenção de parâmetros da CRA e determinação da disponibilidade total de água no solo (DTA) em horizontes superficiais de Latossolos de Sete Lagoas, MG, sob diferentes usos.Amostras indeformadas e deformadas de solo foram retiradas para a obtenção da CRA e caracterização textural. Funções de pedotransferência (FPT) do programa Rosetta foram utilizadas para determinação das CRAs, comparando-as com as obtidas pelo ajuste aos pontos da curva observados nas análises laboratoriais.Determinou-se a DTA dos horizontes em estudo. Constatou-se que os melhores ajustes para as CRAs foram obtidos com a FPT ROS4. Aplicando-se o teste de Friedman, verificou que os valores de DTA, obtidos com as FTPs, diferiram significativamente dos obtidos com método padrão, constatando-se tendência de superestimativa.

No Brasil são semeadas duas safras de milho por ano, fator que contribui para o aumento da incidência e severidade de doenças fúngicas, que reﬂetem em significativas perdas do potencial produtivo da cultura. O objetivo desse trabalho foi avaliar a aplicação de fungicida em híbridos de milho em diferentes estádios fenológicos. O delineamento foi em blocos casualizados com quatro repetições, num esquema fatorial 5 x 2 x 3, sendo cinco híbridos (DG213, Formula TL, CD308, P30K64 e Formula VIP), com e sem azoxistrobina + ciproconazol e água em três estádios fenológicos (V8, VT e R1). As doenças incidentes foram ferrugem polissora, mancha branca e cercosporiose. O uso do fungicida proporcionou maior sanidade às plantas e um aumento médio de 5, 11 e 14% no diâmetro de colmo, massa de mil grãos e massa de espigas, respectivamente. A aplicação em R1 não afetou a viabilidade de grãos de pólen. Os híbridos P30K64 e Formula VIP produziram 31 e 18% a mais, respectivamente. Nos híbridos Formula TL e CD308 o aumento médio na produtividade foi de 17%. Não houve interação para produtividade do DG213 um hibrido duplo precoce. Independente do híbrido, o fungicida em V8, VT, e R1 aumentou em média 18, 30 e 21% a produtividade, caracterizando o pendoamento como a melhor época de aplicação.

There is a growing global quest for clean energy. One of the alternatives is the use of agroenergy, which is the use of vegetable and animal raw material for the production of biofuels. Among them, biodiesel stands out for its renewable and biodegradable nature. The objective of this study was to evaluate the operating performance and smoke opacity of an agricultural tractor fed with different types and ratios of castor bean and Jatropha biodiesels. The study was conducted at Fazenda Experimental CEUNES / UFES, Campus São Mateus - ES. The mixture ratios of biodiesel/diesel used were: B0 (0/100%), B5 (5% 95%), B15 (15%/85% diesel), B25 (25%/75%), B50 (50%/50%), B75 (75%/25%), and B100 (100%/0%). The results showed an increase of 20.0% and 14.8% in the specifc consumption comparing B0 to B100 of castor and Jatropha, respectively. The smoke opacity reduced 24.50% and 54.05% when working with castor and Jatropha biodiesel, respectively. The smoke opacity of the castor B100 is 65.68% higher when compared to Jatropha B100.

Published: May 2018

A temperatura (T) e a umidade relativa do ar (UR) desempenham papéis fundamentais no manejo agrícola, sendo utilizadas, por exemplo, no cálculo da evapotranspiração de referência. Estes dados são obtidos em estações meteorológicas cujos custos variam entre US$1.000,00 e US$10.000,00, tornado-as de difícil acesso para a maioria dos usuários. Assim, o objetivo deste trabalho foi desenvolver um sistema de aquisição e armazenamento de dados de T e UR (SMUT) para fins agrícolas de baixo custo (estimado em US$ 70,00). O Sistema foi construído utilizando um sensor DHT22 (AM2302) instalado em um abrigo, um relógio de tempo real (RTC), um gravador de cartões SD, acoplados à uma placa Arduino, programado para leituras a cada dez minutos e cálculo de médias T e UR a cada hora. Para comparação, o sistema foi instado junto a duas estações meteorológicas automáticas (Posto Meteorológico EA/UFG), em Goiânia-GO, e fez-se coleta de dados de Outubro a Dezembro de 2016. Os dados foram comparados através de análise de regressão, erro padrão de estimativa (EPE), raiz quadrada do erro quadrático médio (RMSE), média do erro absoluto (EMA), coeficiente de correlação simples de Person (r) e índice de concordância (d) de Willmott. Os resultados mostraram que houve correlação entre os dados do SMUT e das outras estações (r>0,87), com erro padrão em torno de 6% e ótimo grau de exatidão (d>0,99). Portanto, recomenda-se o uso do SMUT para o monitoramento agrícola de T e UR na faixa de 17 a 35oC e 32 a 100%, respectivamente.

Published: May 2018

As alterações climáticas e as suas consequências vêm sendo uma das grandes preocupações da humanidade e, neste tocante, a precipitação pluviométrica tem atenção espacial nos estudos ambientais. Com este trabalho, objetivou-se utilizar uma ponderação por meio da modelagem fuzzy e métodos geoestatísticos para estudar a propagação de incertezas da precipitação pluviométrica e do potencial erosivo das chuvas para o estado da Bahia. Foram utilizados os valores de precipitação pluvial levantados para 71 postos pluviométricos localizados na área do estado, avaliando-se a média anual das séries históricas usadas. Para cada posto pluviométrico, foram calculados os valores de erosividade, através da relação entre a precipitação média mensal e a precipitação média acumulada anual. Os dados foram submetidos primeiramente à análise estatística clássica, seguida da geoestatística para modelar a variabilidade espacial dos fenômenos estudados. Foi realizada uma codificação para modelagem através de krigagem por indicação e também classificação segundo modelos fuzzy, utilizando para a precipitação modelos exponenciais e para a erosividade modelos lineares. A lógica fuzzy se mostrou mais eficiente nos estudos ambientais quando comparada à krigagem por indicação. Os valores resultantes das análises de erosividade mostrou que, na maior parte do estado, as chuvas possuem elevado potencial para causar erosão, com um limite acima do aceitável.

Decomposing scripts: Ethnography and writing about writing
Authors: McNamara Joshua
Published: May 2018

As a field whose founding gesture has been to go behind and before the audio-visual text, screenwriting scholarship has become an exciting new frontier for ethnographic approaches to writing about writing. However, so far there has been very little attention paid to what doing an ethnography of script writing might actually entail. What challenges are specific to writing an ethnography on the practices of writing a script? What opportunities does working on script writing offer us as scholars seeking to establish a better understanding of both the narratological and discursive qualities of the practice of writing itself? Rather than retreat to a familiar understanding of ethnography as documentary observation, this article proposes that productive answers to these questions might be found in turning to more experimental approaches to writing ethnography. Understanding the script as a unique kind of writing that anticipates its own death as writing, this article suggests a new genre of ethnographic writing, one not simply appropriated from cultural anthropology, but expressed within the specificity and strictures of researching screenwriting. I call this genre of writing about writing in anticipation of death, a decomposition.
Writing-for-the-cut: What can screenwriters learn from film editors about storytelling?
Authors: Loftin Greg
Published: May 2018

This article explores an approach to screenwriting using storytelling dynamics found in film editing. I call this ‘writing-for-the-cut’. This idea finds its roots in the lively theories and debates of early Soviet filmmakers such as Lev Kuleshov and Sergei Eisenstein in the 1910s and 1920s. They viewed editing as a juxtapositional dynamic, one that invites the audience to ‘discover’ the story for themselves. From their Hegelian notion of juxtaposition to its more nuanced application today, I discuss three kinds of cinematic juxtaposition: suggestion, puzzle and kinesis. I then explore how these dynamics might be embedded in the screenplay.
The policy filtering process: Understanding distinctive state responses to the National College Completion Agenda in the United States
Authors: Rubin Paul G. , Hearn James C.
Published: May 2018

The United States has faced stagnant postsecondary education degree completion rates for over a decade. When coupled with improved educational outcomes in other nations, the one-time world leader in higher education attainment has precipitously declined in standing internationally. Coupling this reality with the need for a more educated workforce domestically led President Barack Obama to proclaim improving higher education completion rates a national imperative in 2009. Despite input from the federal government, due to the decentralized nature of American postsecondary education, individual states maintain primary responsibility for governance and policy decisions. Consequently, there has been a range of state responses to improving college completion. Through a comparative case analysis, this study considers a putatively homogenous region to investigate state-level factors that “filtered” the national college completion agenda to distinct responses in Georgia, South Carolina, and Texas.

The usage of alternate fuels has been a priority ever since the depletion of the conventional fuels. During the recent
times the concept of using biodiesel as fuel has been predominant due to its ability to be used in the same engine as
conventional fuels. The source of biodiesels are mainly non edible oils such as Jatropha and Pongamia. This paper
reviews the properties of the alternate fuels when used in the compression-ignition engine. These alternate fuels used
are vegetable oils and alcohols. The review compares the key properties of diesel to the alternate fuels used. The
properties such as such as brake thermal efficiency, volumetric efficiency, exhaust gas temperature and smoke levels
are compared with the values obtained from the usage of conventional diesel fuel in a low heat rejection engine
(L.H.R) engine. apart from the properties there is also a need for the check of pollutants emitted during the processes,
oxides of nitrogen from diesel fuel and aldehydes from the alternate fuels.

Trois regards sur la notion de « culture chinoise »
Authors: Zimmermann Basile
Published: May 2018

Chinese studies are going through a period of reforms. This article appraises what could constitute the theoretical and methodological foundations of contemporary sinology today. The author suggests an approach of “Chinese culture” by drawing from recent frameworks of Science and Technology Studies (STS). The paper starts with current debates in Asian studies, followed by a historical overview of the concept of culture in anthropology. Then, two short case studies are presented with regard to two different STS approaches: studies of expertise and experience and the notion of interactional expertise, and the framework of waves and forms. A general argument is thereby sketched which suggests how “Chinese culture” can be understood from the perspective of materiality.

Published: May 2018

An important clinical potential of cold atmospheric plasma (CAP) lies in tumor and wound treatment, whereby the last-mentioned is well-referenced already. However, the underlying mechanisms of improved wound healing have not been sufficiently clarified yet, in particular the influence of CAP on microcirculation. Hyperspectral imaging (HSI) enables the visualization of microcirculation of large tissue areas, thus this technique seems to be a candidate to examine CAP effects on perfusion and oxygen saturation in wounds. During clinical wound management, one chronic wound caused by peripheral arterial occlusive disease and one acute wound after surgical removal of cervical lymph nodes were examined using HSI before and after CAP treatment. HSI was able to demonstrate CAP effects on microcirculation showing a relevant increase of superficial and deeper cutaneous oxygen saturation together with elevated hemoglobin concentration in treated and also surrounding wound area. For the first time, it was shown that CAP improves the superficial and deeper oxygenation and hemoglobin perfusion in and around the treated area of acute and chronic wounds. This effect may contribute to healing support by CAP in wounds. HSI seems suitable for evaluating and monitoring CAP effects in clinical settings.

We present some recent results on Hardy spaces of generalized analytic
functions on D specifying their link with the analytic Hardy spaces. Their
definition can be extended to more general domains Ω . We discuss the way to
extend such definitions to more general domains that depends on the
regularity of the boundary of the domain ∂Ω. The generalization over general
domains leads to the study of the invertibility of composition operators
between Hardy spaces of generalized analytic functions; at the end of the
paper, we discuss invertibility and Fredholm property of the composition
operator C∅ on Hardy spaces of generalized analytic
functions on a simply connected Dini-smooth domain for an analytic symbol

A metric-based approach to multiphase mean curvature flows with mobilities
Authors: Bretin Elie , Danescu Alexandre , Penuelas José , Masnou Simon
Published: May 2018

We summarize in this note a few theoretical and numerical results described with more details in the forthcoming paper [5] devoted to a new phase field model for approximating mean curvature flows. Our work is motivated by the simulation of multiphase mean curvature flows with possibly inhomogeneous surface tensions and mobility coefficients. The key aspect of our model is to incorporate the mobilities not in the phase field energy (which is conventionally the case) but in the metric which determines the gradient flow. We show the consistency of such approach by a formal analysis of the sharp interface limit. We also propose an efficient numerical scheme which allows us to illustrate the advantages of the model on various examples, as the wetting of droplets on solid surfaces or the simulation of nanowires growth generated by the so-called vapor-liquid-solid method.

Published: May 2018

Recently, the notion of positive linear operators by means of basic (orq-) Lagrange polynomials and𝒜{\mathcal{A}}-statistical convergence was introduced and studied in [M. Mursaleen, A. Khan, H. M. Srivastava and K. S. Nisar, Operators constructed by means ofq-Lagrange polynomials andA-statistical approximation, Appl. Math. Comput. 219 2013, 12, 6911–6918]. In our present investigation, we introduce a certain deferred weighted𝒜{\mathcal{A}}-statistical convergence in order to establish some Korovkin-type approximation theorems associated with the functions 1,tandt2{t^{2}}defined on a Banach spaceC⁢[0,1]{C[0,1]}for a sequence of (presumably new) positive linear operators based upon(p,q){(p,q)}-Lagrange polynomials. Furthermore, we investigate the deferred weighted𝒜{\mathcal{A}}-statistical rates for the same set of functions with the help of the modulus of continuity and the elements of the Lipschitz class. We also consider a number of interesting special cases and illustrative examples in support of our definitions and of the results which are presented in this paper.
Some variational principles associated with ODEs of maximal symmetry. Part 1: Equations in canonical form
Authors: Ndogmo Jean-Claude
Published: May 2018

Variational and divergence symmetries are studied in this paper for linear equations of maximal symmetry in canonical form, and the associated first integrals are given in explicit form. All the main results obtained are formulated as theorems or conjectures for equations of a general order. Some of these results apply to linear equations of a general form and of arbitrary orders or having a symmetry algebra of arbitrary dimension.
Subspace-based algorithm for distance networks
Authors: Norrdine Abdelmoumen
Published: May 2018

A three-dimensional distance network is composed of a system of points or nodes located on earth’s surface or in space, in a building or in a construction site. Localization of these nodes is a fundamental operation in geodetic and sensor networks. This paper shows a new method for calculating n-dimensional dynamic distance networks, whereas a spectral decomposition of a symmetric matrix of squared distances is used. Thereby neither approximation, nor iterative solutions are used. By using this method, fixed reference points can be selected as well as noisy distances can be denoised and checked for consistency. Given a realistic scenario, Monte-Carlo simulations show that the proposed method always converge to an optimal solution with less computation time than numerically optimized Levenberg-Marquandt method.
Parameter identification for the linear wave equation with Robin boundary condition
Authors: Bacchelli Valeria , Pierotti Dario , Micheletti Stefano , Perotto Simona
Published: May 2018

We consider an initial-boundary value problem for the classical linear wave equation,
where mixed boundary conditions of Dirichlet and Neumann/Robin type are enforced at the endpoints of a bounded interval.
First, by a careful application of the method of characteristics, we derive a closed-form representation
of the solution for an impulsive Dirichlet data at the left endpoint, and valid for either a Neumann or a Robin
data at the right endpoint. Then we devise a reconstruction procedure for identifying both the interval length and
the Robin parameter. We provide a corresponding stability result and verify numerically its performance moving
from a finite element discretization.
Proximization and literature: Marquez’s “a very old man with enormous wings”
Authors: Farsi Roghayeh
Published: May 2018

This paper applies the politics-based theory of Discourse Space to a literary text in order to investigate its flexibility and possible contribution to literary interpretation. As a case study, Gabriel Garcia Marquez’s short story, “A very old man with enormous wings” has been selected; this story most obviously evolves out of dichotomies on both inter- and intra-character levels. The theory’s proximization model is the main core of the analysis based on which the role of the deictic centre in positioning the story’s entities is accentuated. The analysis shows that despite its advantages, the proximization model needs to be expanded in order to accommodate the variety of deictic centres which any literary text, unlike political discourse, has. A comparison between Discourse Space Theory and narratology shows the inadequate attention the latter assigns to the axiological and evaluative role of the deictic centre in the story.

Authors: García-Salido Alberto , Melen Gustavo , Gómez-Piña Vanesa , Oñoro-Otero Gonzalo , Serrano-González Ana , Casado-Flores Juan , Ramírez Manuel
Published: May 2018

Background:

The receptor for advanced glycation end products (RAGE) has a critical role in the pathogenesis of inflammation. In healthy children, its basal expression on the peripheral blood mononuclear cell (PBMC) and the basal circulating soluble RAGE (sRAGE) levels are unknown. The aim of this study was to describe both.

Methods:

This is a monocentric, observational and descriptive study of samples obtained from healthy children. The RAGE expression on PBMC was analyzed using flow cytometry. The sRAGE values were determined with a specific sandwich enzyme-linked immunosorbent assay (ELISA) kit, later the relation between cellular RAGE and sRAGE was described.

Results:

Forty-three children were included. The median sRAGE level was 849.0±579.0 pg/mL. The RAGE mean fluorescence intensity (MFI) was 1382±506 in monocytes and 792±506 in lymphocytes. There were no differences between genders. A negative correlation was found between sRAGE and RAGE MFI in lymphocytes (r=−0.3; p=0.04).

Conclusions:

We describe for the first time the RAGE surface levels on PBMC in children. It showed a negative correlation with sRAGE. The sRAGE circulating level is lower than the sRAGE level described in adult population or non-healthy children. Our findings should be confirmed in order to apply them as reference values for future investigations.
Subordinate and interrogative clause negation in Iquito
Authors: Hansen Cynthia
Published: May 2018

This paper describes a specific non-standard negation strategy in Iquito, a moribund Zaparoan language spoken in northern Peruvian Amazonia. This strategy is used in finite subordinate clauses (namely adverbial dependent clauses and relative clauses), as well as information questions, and it utilizes two negative markers: a negative particle which is also found in standard negation, and a verbal affix which does not function as a negator in any other context. Using existing typological characterizations of subordinate clause negation, we see that Iquito exhibits the following attested traits: it uses the standard negator in a different position, it also utilizes a distinct negator, and it employs more negators in the subordinate clause than in the main clause. But unlike the languages presented in the literature, Iquito utilizes these parameters simultaneously. Additionally, the position of the standard negator changes within the subordinate clause, depending on the reality status of the clause. Using Iquito as a case study, I propose a set of parameters for comparing subordinate clause and interrogative negation strategies to standard negation strategies, which include the type of negator used, its position, the overall number of negators, the potential for interaction with other grammatical categories, such as reality status, and the resulting word order of the clause. This set of parameters expands the initial typological characterizations of subordinate clause negation strategies.
The conservation status of a poorly known range-restricted mammal, the Nimba otter-shrewMicropotamogale lamottei
Authors: Monadjem Ara , Decher Jan , Crawley Wing-Yunn , McCleery Robert A.
Published: May 2018

We have a poor understanding of the ecology of many African small mammals due to a lack of basic research. This has important conservation implications, particularly for range-restricted species in tropical regions. In this study, we provide new insight into the distribution and ecology of one such species, the Nimba otter-shrew (Micropotamogale lamotteiHeim de Balsac 1954). We apply niche and occupancy modeling to inform on the range and habitat use of this semi-aquatic species. We estimate that its global range [extent of occurrence (EOO)] is 14,725 km2. Using occupancy modeling, we show that mining has a direct impact on the occurrence of this species. We also provide preliminary observations of its movements through radio-tracking. Using maximum entropy (Maxent) modeling, we identify the North Lorma National Forest and the Wonegizi range (northern Liberia) that appear suitable for this species, but where it has not yet been recorded. We suggest that the Nimba otter-shrew has a global distribution centered on the Mount Nimba region, straddling the borders of Liberia, Guinea and Côte d’Ivoire, and that it requires urgent conservation attention to ensure its long-term persistence. Finally, we provide evidence to support an uplisting of its IUCN Red List conservation status to Vulnerable.
An Integrated Throughflow Method for the Performance Analysis of Variable Cycle Compression Systems
Authors: Liu Baojie , Jia Shaofeng , Yu Xianjun
Published: May 2018

A streamline curvature method based integrated throughflow analysis approach is newly developed to deal with component matching problems of variable cycle compression systems. The construction of variable cycle compression system is modularly modelled in the procedure. Splitting and confluent flow are elaborately disposed. A numerical method based on the “streamline floating” character of streamline curvature method is developed to model the function of forward variable area bypass injector. Moreover, extensive models used in the throughflow calculations, including minimum loss incidence, deviation and loss models were assessed, selected and modified. Finally, code validations were conducted on three representative traditional compressors, i. e. NASA rotor 67, NASA stage 37 and a custom-designed low-speed repeating four-stage compressor. Both the predicted overall characteristics and spanwise profiles agree reasonably well with the experimental data. The validated procedure was finally used to sketch the performance maps of a double bypass compression system under two different control rules, i. e. the first bypass throttling and the second bypass throttling. The results show some aspects of the difficulties and complications in operating a variable cycle compression system, and meanwhile, demonstrate the superiority of the newly developed integrated throughflow method.
Herausforderungen bei der Messung von Wohlfahrt
Authors: Jochimsen Beate , Raffer Christian
Published: May 2018

Initiiert von einer lebhaften öffentlichen und wissenschaftlichen Debatte um die Eignung des Bruttoinlandsprodukts als Indikator für materiellen Wohlstand sind zahlreiche alternative Maße zur Wohlstands- und Wohlfahrtsmessung entwickelt worden. Fällt dabei die Wahl auf einen Indikatorensatz, ist die Bestimmung der optimalen Anzahl der Indikatoren eine zentrale Herausforderung. Je mehr Indikatoren ausgewählt werden, desto besser können zwar die Bestandteile der Wohlfahrt abgebildet werden, desto schlechter ist aber die Kommunizierbarkeit. Beate Jochimsen und Christian Raffer analysieren mit Hilfe mehrerer statistischer Methoden die Verbindungen der 10 W³-Leitindikatoren des Deutschen Bundestages untereinander. Es zeigt sich, dass bis zu vier dieser Indikatoren ohne großen Informationsverlust weggelassen werden können, da sie mit den verbleibenden eng korreliert sind. Ein kleinerer W³-Indikatorensatz könnte wesentlich leichter erklärt und kommuniziert werden. Im Ergebnis bedeutet dies, dass der Umfang aller, nationaler und internationaler, Indikatorensätze zur Wohlfahrtsmessung kritisch zu würdigen ist.
Synchronisation and Circuit Realisation of Chaotic Hartley System
Authors: Varan Metin , Akgül Akif , Güleryüz Emre , Serbest Kasım
Published: May 2018

Hartley chaotic system is topologically the simplest, but its dynamical behaviours are very rich and its synchronisation has not been seen in literature. This paper aims to introduce a simple chaotic system which can be used as alternative to classical chaotic systems in synchronisation fields. Time series, phase portraits, and bifurcation diagrams reveal the dynamics of the mentioned system. Chaotic Hartley model is also supported with electronic circuit model simulations. Its exponential dynamics are hard to realise on circuit model; this paper is the first in literature that handles such a complex modelling problem. Modelling, synchronisation, and circuit realisation of the Hartley system are implemented respectively in MATLAB-Simulink and ORCAD environments. The effectiveness of the applied synchronisation method is revealed via numerical methods, and the results are discussed. Retrieved results show that this complex chaotic system can be used in secure communication fields.
