Crafting an ‘authentic’ monster: Dialogue, genre and ethical questions in Mindhunter (2017)
Authors: Moulton Erica
Published: August 2019

Extended scenes of idiosyncratic dialogue between a serial killer and profiler are emblematic of the first season of Joe Penhall and David Fincher’s Netflix series Mindhunter. In examining this aspect of the series, my article engages with several burgeoning areas of study in screenwriting and adaptation, notably the intersection of ethics, genre and dialogue. Mindhunter falls squarely into the serial killer subset of the crime procedural genre, following two FBI agents as they interview incarcerated killers under the purview of the newly formed Behavioral Science Unit. In exploring the origin and deployment of highly psychologized speech, I argue that conventions within the serial killer subgenre and the invocation of non-fictional source material led the show’s writers to rely on codes of ‘authenticity’ in crafting the dialogue. Building on studies of screenwriting and genre by Jule Selbo, I also argue that the interview scenes depicted on Mindhunter between the FBI agents and the serial killers can be broken down into various dialogue typologies. The dialogue in these scenes presents the killer as a fount of wisdom, the investigator as an eager receptacle and the psychological boundaries between the two characters as disturbingly permeable. I conclude by probing the ethical underpinnings of this typology considering how screenwriters navigate the tensions between on-screen representation and the framing of ‘authentic’ content.
Kurosawa to Kasdan: Storytelling influences
Authors: Davies Brett
Published: August 2019

Lawrence Kasdan is one of the most commercially successful screenwriters of the past forty years. In addition to writing Raiders of the Lost Ark (1981) and four episodes of the Star Wars saga, Kasdan has gained critical acclaim as the writer-director of seminal 1980s ‘baby-boomer’ films, such as The Big Chill (1983) and The Accidental Tourist (1988). Known for ‘genre-hopping’, it is perhaps Kasdan’s very versatility that has led to a marked lack of academic discourse on his work, as his eclectic canon – including westerns, neo-noir, sci-fi horror, comedy and romantic thriller – makes it problematic for scholars to establish prevalent patterns in his output. This article argues that one influence has remained constant throughout Kasdan’s career: the work of Akira Kurosawa. Examining three screenwriting elements – dialogue, protagonists, themes – the article will demonstrate how Kurosawa’s storytelling style has repeatedly informed Kasdan’s work, from his earliest screenplays (Kasdan said that ‘there’s a lot of Kurosawa in Raiders’) to his most recent, as The Force Awakens (2015) and Solo: A Star Wars Story (2018) showed stylistic connections with Kurosawa’s films, beyond those already established by George Lucas’s original Star Wars (1977).

The Challenge of Preserving the Artifacts of Optometric History
Authors: Cole Barry L.
Published: August 2019

This paper looks at optometry museums around the world. There are only five general optometry museums: three are hosted by optometric institutions in three countries, Australia, Britain and the U.S.A., one is hosted by a Canadian university that has an optometry school, and one is in private hands in Southbridge, Massachusetts. They are supplemented by six excellent corporate museums in France, Germany and Italy, but these museums focus on either spectacles or ophthalmic instruments, rather than optometry in general. Two of the optometry museums were founded over 100 years ago, and two have had their 50th birthday, but can they survive forever? Museums are expected to preserve collections for posterity for the edification and enjoyment of future generations, yet all institutions are at risk of disruption: few institutions last more than a couple of hundred years. This paper discusses strategies optometry museums might pursue to guard against mismanagement and neglect and provide for the protection of their collections in the event of the demise of the museum or its host institution.

Strength based design is commonly used in the design of resisting earthquake building. It is analyzed by linear elastic method so that it can’t describe the seismic behaviour of the structures. For that reason, the design of structure needs to consider performance based design. Irregularity of structure play important role for the results of Structure Performance. This paper uses five models of 20 storey reinforced concrete building with same height(76 m) and areas(750m2) with different plan configurations: rectangular, T, L, U, and H-shaped. Non linear time history method is used  to investigate the seismic behaviour of the structures, using finite model with ETABS2016. Dimension of structures are column (600 x1000 mm), shear wall (400mm), couple-beam (400x900 mm), slab (140mm). Recorded accelorogram used in this paper are Altadena, Array, Corralit, LACC, and Yermo because it has almost same earthquake mechanism, magnitude, and epicentrum distance, so that they are used as an artificial accelorogram that is synthesized using Wavelet Function according to SNI 1726-2012.Result shows that the story drift and plastic hinges for collapse prevention (CP) are: rectangular (story drift is 0.59% and amount of CP hinges are 8), H-shaped (1.58%/23), L-shaped (2.41%/30), U-shaped (4.59%/35), T-shaped (5.8%/58).

The number and growth of vehicles, is a separate issue associated with sustainable transportation. In 2014, recorded vehicle election in Indonesia reached more than 448 vehicles per 1,000 people. And specifically, for motorcycles reach 365 vehicles per 1,000 people. The growth of motor vehicles is significantly influenced by economic growth (measured by Gross Domestic Product - RGDP). When compared with motor vehicle growth, it can be concluded that the high growth rate of motor vehicles at the end of this decade actually impact on the decrease of RGDP. To see the trend between economic growth represented by RGDP and the growth of motor vehicle (motorcycle) needs a model. Motor vehicle growth model in Java can be approached with Gompertz function. This function is a negative exponential function with asymptote used is the highest value of motor vehicle ownership in DKI Jakarta Province is 1,299 motorcycles per 1,000 people.

Seismic performance of reinforced concrete frame Buildings which have been designed as Special Moment Resisting Frames in accordance to three Indonesian codes (SNI 1727-2013, SNI 1726-2012 and SNI 2847-2013) can be evaluated using nonlinear dynamic analysis. Criteria related to strength such as component plastic rotation capacity, lateral displacement as well as criteria related to damage of elements in the structures were used to evaluate the seismic performance of the buildings. Assessment to the moment and curvature capacities of the cross sections of beams and columns were done using XTRACT. The global seismic performance of the structures depends on the seismic performance of components in the structures. In nonlinear model of the structures, the degrading strength of the components were modeled to take into account the gradual reduction of the contributed components to the resistance of the structures. PERFORM-3D is one of the software that can be used to generate nonlinear model of structures. Seismic performance level of structures can be obtained from the results of the nonlinear dynamic analysis using PERFORM-3D. The Seismic performance level can be utilized for: (1) detecting any weaker part in the structures, and (2) evaluating the improved design of the structures for enhancing the seismic performance of structures.

To achieve the target of 100% drinking water service, Central Java Provincial Government holds regional water supply system (SPAM) programmes in Central Java, one of which is Keburejo regional water supply system (Kebumen and Purworejo). During the development phase, it was delayed due to project cost overrun, which later promotes an option for Public-Private Partnership (PPP). Consequently, this option may increase the project risks. This study aims to identify and analyze the risks of Keburejo regional water supply system project when the PPP option is chosen. This research adopted a mixed research method of qualitative and quantitative approach. Respondents in this study were 22 respondents from PDAB Tirta Utama, Dinas Bina Marga and Cipta Karya (BMCK) Central Java, Satker PSPAM Central Java, BBWS Serayu Opak, Pemkab (PDAM, Bappeda and DPU) Kebumen and Purworejo, as well as Business Entity (PT. TGM). The results found 24 risk factors, classified into pre-construction (10), construction (4), and Operational and Maintenance (10). The majority of these risks are considered ‘High’ (83.33%), with the highest risks in the pre-construction (37,5%), and the majority is under the Government responsibility (66.67%). These results are useful for Government as a reference in managing the risks of PPP SPAM Regional Keburejo and other regional SPAM projects in Indonesia.
Respons Dinamik Pelat Beton Akibat Beban Kendaraan yang Bergerak dengan Kecepatan Konstan
Authors: Liucius Yenny Untari , Alisjahbana Sofia W
Published: August 2019

This analysis studies about the dynamic response of isotropic slab with the semi rigid type of edge conditions which is solved by the Modified Bolotin Method. The dynamic response mostly depends on the characteristics of the slab and the velocity of the transverse load acting on the slab. This analysis uses 10 km/h, 20 km/h, and 30 km/h as the velocity of the transverse load, and 110 km/h as the comparing velocity. Results show that maximum dynamic responses for each velocity does not always occur on the center of the slab, so the characteristics of the slab may be vary. The dynamic response is closest to maximum when the velocity of the load is 110 km/h because it is closer to the critical velocity of the system which is 112 km/h. This analysis assumed the slab is used for the bus’ parking ramp. Thus with the 10 km/h until 30 km/h velocity assumption for parking ramp is still quite safe because the velocity is far below the critical velocity of the system. Also the dynamic response of the system is far lower than the maximum response of slab.

The concrete structure exposed to high temperatures can affect the strength of the structure. Limitations in the experimental method can be solved by mathematical modeling. This study aims to identify the stress and strain behavior that occurs at high-temperatures. The model is a cylindrical concrete with a diameter of 150 mm and a height of 300 mm. The concrete strength design is 25 MPa. The temperatures of the model are 100 °C, 200 °C, 300 °C, 400 °C, 500 °C, 600 °C, and 700 °C. The model analysis using LUSAS v. 16 Software to observe the properties of the concrete material due to exposure to high temperatures. The results of the study get the higher the temperature received by concrete, the strength of the concrete decreases. Concrete that burned to a temperature of 300 °C still had 82% available power, and at a temperature of 700 °C, the remaining concrete strength was 30%. The strain increases to 423% from normal conditions at a temperature of 700 ° C. Therefore, the results of the study can be used as a reference for structural engineers to know the behavior of the concrete that exposure to high temperatures.

The behavior of reinforced concrete frame with infill wall (RDP) has been studied numerically by modeling the RDP structure using the LUSAS software. The results were compared to other researchers’ results that conducted laboratory test and used SAP programs. The results of analysis using SAP show that the proposed model that subjected to load up to the maximum limit show similar behavior to the laboratory tests results in which parameters such as secant modulus for concrete and wall materials based on graphs of stress-strain relationships and a reduction in moment of inertia due to the crack of beam-column are taken into account. The model using LUSAS did not adopt this method instead applied plastic elastic material and non-linear analysis. The results of the analysis are still not in proportional to the magnitude of the laboratory test results, but the behavior of the load and deflection indicates similar form. The analysis models show the maximum stress points that occur on the wall similar to that with the pattern of failure in laboratory testing. The maximum stress occurs at the opening corner and the beam column joint corner that is in line with the results of laboratory testing.

SNI 1726:2012 states that surface spectral accelerations SMS (0.2 second) and SM1 (1 second) can be calculated by multiplying site factors Fa (0.2 second) and Fv (1 second) with spectral accelerations SS (0.2 second) dan S1 (1 second). All site factors used by SNI 1726:2012 are adopted from ASCE/SEI 7-10.  In 2013 Stewart and Seyhan proposed new and different site factors compared to ASCE/SEI 7-10. These site factors are then used for developing ASCE/SEI 7-16 with minor improvement for site class SE (soft soil). ASCE/SEI 7-16 states that the site factors for site class SE with SS greater than 1g or S1 greater than 0.2g, shall be calculated using Site Specific Analysis (SSA). The SSA method used for calculating site factor is difficult for ASCE/SEI 7-16 to be implemented in Indonesia. This paper describes the result of SMS and SM1 study at five cities (Jakarta, Bandung, Semarang, Yogyakarta and Surabaya) for site class SC, SD and SE using site factors proposed by Stewart and Seyhan and site factor SNI 1726:2012. The SMS and SM1 at five cities calculated using site factors proposed by Stewart and Seyhan are ±15% differences compared to SMS and SM1 calculated usingSNI 1726:2012 site factors.
Przez język ukrycia po słowo na „g”. Kim są bohaterowie czasów queer before gay?
Authors: Nowak Tomasz Łukasz
Published: August 2019

Who (and what) was silent about the story told by heteronormative society? And how is the fragment of this story seen by “Others”? The article shows that the time of “queer before gay” includes (in Polish) not only well-known names such as: aunt or pedal, but also slang: ‘lala’ (doll), ‘przyjaciółki’ (friends), ‘siostry’ (sisters in Polish, girls in English), gays “from the outside of society”, as well as heterosexuals who got a ticket to the alternative world of the excluded. I tell this story from the perspective of the performative function of language (Althusser, Austin, Butler) and mechanisms of knowledge/power (Foucault). I focus on the activities of homosexual men encoded in their “hiding language” (sociopolitan gay). I show how the creation of the “homosexual” identity closed the community of aunts and pedals in a precisely defined form. And how camp and queering reality allowed them to function in this form. This article is thus another element of decoding the so-called language of concealment, so-called sociolect of Polish gays (aunts and pedals) and queering history of Poland (part of the queering history of Central and Eastern Europe).

Este trabalho, utiliza a metodologia “ensino em espiral”, com a finalidade de levar os alunos a compreender a relação dos fenômenos físicos, térmicos e naturais: inversão térmica, efeito estufa, ilhas de calor e aquecimento global, abordando os conceitos de umidade, radiação infravermelha e pressão atmosférica. Para isso, utilizou-se aulas práticas com experiências de materiais de baixo custo, mapa conceitual e o LEGO. Nas aulas, aplicou-se uma sequência didática metodológica cujo objetivo foi incentivar a reflexão sobre os conceitos ambientais trabalhados, além disso, os estudantes foram submetidos a uma análise qualitativa e quantitativa por meio de redação, com intuito de comprovar a eficiência da proposta didática. Os dados foram obtidos na escola estadual de ensino médio Lourenço Galleti na cidade de Açailândia – MA. Portanto, verificou-se que os resultados dos alunos avaliados forma significativos com relação aos conceitos abordados. Ainda aplicou-se o método estatístico (ANOVA), através do qual foi possível avaliar o nível de compreensão dos estudantes entre as turmas do terceiro ano A e C envolvidas na pesquisa. Com esse método observou-se a disparidade entre os níveis de aprendizagem das duas turmas, a turma C apresentou resultados melhores significativamente do que a turma A. Dessa forma, conclui-se que a proposta se torna eficaz, desde que haja uma análise dos conhecimentos prévios e dos possíveis obstáculos epistemológicos de cada turma afim de obterem o mesmo rendimento com a intervenção docente.

Atualmente, nas aulas de física do ensino médio, salvo raras exceções, observa-se uma disparidade com relação às atividades de ensino aprendizagem em física: de um lado, professores que ensinam fórmulas (receitas) para resolução de problemas, e do outro, estudantes com inúmeras dificuldades na compreensão da maioria dos conteúdos de física. Hoje em dia, torna-se inconcebível a ideia de se fazer ensino sem a inserção de ferramentas computacionais na análise científica ou em atividades experimentais de um modo geral, principalmente quando dessa prática, requer-se uma compreensão ampla sobre os fenômenos envolvidos nessa análise. Acredita-se que o desenvolvimento de atividades utilizando placas de prototipagem assim como o Arduino quer por sua versatilidade, custo, dentre outros, aliadas às teorias de ensino, em especial, voltadas ao ensino de física, talvez seja a linha de pesquisa que tenha dispensado maiores esforços e investimentos nos últimos anos há diversas pesquisas na área disponíveis na literatura. Nesse artigo, apresenta-se os resultados quanto à implementação de atividades experimentais utilizando a placa como ferramenta auxiliar de ensino abordando conteúdos de Cinemática, Termometria e Eletrodinâmica voltadas aos estudantes do ensino médio de uma escola da Rede Pública Estadual do município de Marabá - Pará.
Modelos mentais para representação atômica numa perspectiva de aprendizagem significativa
Authors: Pires Adriano Rego , Novais Andréa de Lima Ferreira , Gomes Luiz Moreira , Ferreira Fernanda Carla Lima
Published: August 2019

Em diversas áreas da ciência é comum utilizar o termo modelo como uma representação analógica de um fenômeno, relacionando-o as memórias cotidianas para obter um quadro mental que possibilite a sua compreensão. Ao utilizar esse termo para definir fenômenos atômicos é necessário um amplo grau de abstração, pois o mesmo se distancia do cotidiano exigindo representações análogas a realidade. A partir da compreensão de que o termo modelo é em muitas áreas utilizado como uma representação abstrata é que este trabalho torna-se imprescindível. Outra importante contribuição é analisar a didática utilizada pelos professores de Ciências ao abordarem esse termo em suas práticas. Além do processo de formação dos modelos mentais na perspectiva da construção de conhecimento. O presente trabalho analisou um questionário contendo 3 (três) questões referentes a, por exemplo, constituição e movimento atômico. As análises realizadas após a aplicação do questionário revelaram dificuldades relacionadas ao processo em que ocorre o ensino e aprendizagem acerca do conteúdo referente aos modelos atômicos e nas representações e estruturas cognitivas utilizadas.

Também foi realizado um levantamento de dados nas escolas pesquisadas através de questionário abordando o Ensino de Física e questões didáticas e pedagógicas que se relacionam com o objeto de estudo. A partir dos dados, observamos que há semelhanças e diferenças no Ensino de Física das escolas dos municípios supracitados. De modo geral, ambas as experiências investigadas demonstram que é necessário investir nas escolas públicas com recursos financeiros e na formação de professores para o Ensino de Física
Some hemivariational inequalities in the Euclidean space
Authors: Bisci Giovanni Molica , Repovš Dušan
Published: August 2019

The purpose of this paper is to study the existence of weak solutions for some classes of hemivariational problems in the Euclidean space ℝd(d≥ 3). These hemivariational inequalities have a variational structure and, thanks to this, we are able to find a non-trivial weak solution for them by using variational methods and a non-smooth version of the Palais principle of symmetric criticality for locally Lipschitz continuous functionals, due to Krawcewicz and Marzantowicz. The main tools in our approach are based on appropriate theoretical arguments on suitable subgroups of the orthogonal groupO(d) and their actions on the Sobolev spaceH1(ℝd). Moreover, under an additional hypotheses on the dimensiondand in the presence of symmetry on the nonlinear datum, the existence of multiple pairs of sign-changing solutions with different symmetries structure has been proved. In connection to classical Schrödinger equations a concrete and meaningful example of an application is presented.

Authors: Goto Kohei , Taniguchi Jun
Published: August 2019

Methods for fabricating micro- and nanoscale three-dimensional (3D) structures such as electron-beam lithography (EBL) attracted attention in various fields. In EBL, an acceleration-voltage modulation method can be used to control the developing depth of the structure. In this study, we fabricated a rose petal structure using acceleration-voltage modulation. Using a rose petal mold, plastic- and silver-duplicated rose petals were prepared using nano-imprint lithography (NIL). We demonstrated that various complex 3D structures and materials can be duplicated using NIL by applying an acceleration-voltage modulation method.
Die rechtlichen Hintergründe der Neuregelung der Sonntagsöffnung öffentlicher Bibliotheken in Nordrhein-Westfalen
Authors: Steinhauer Eric W.
Published: August 2019

Will man eine Sonntagsöffnung öffentlicher Bibliotheken ermöglichen, so ist dies ohne gesetzgeberische Maßnahmen nicht möglich. Soll neben der bloßen Öffnung des Gebäudes auch Bibliothekspersonal am Sonntag beschäftigt werden, kann auf eine arbeitszeitrechtliche Regelung nicht verzichtet werden. Solange der Bund hier keine Neubestimmung der Ausnahmen in § 10 ArbZG vornimmt, bleibt für die Länder nur der Weg über eine Regelung in eigenen Bedarfsgewerbeverordnungen. Nordrhein-Westfalen wird diesen Weg nach Hessen als zweites Bundesland beschreiten. Im Gegensatz zu Hessen wurde die geplante Regelung aber sorgfältiger ausgearbeitet und begründet. Ob dies einen Rechtsstreit wie im Fall Hessens verhindern wird, bleibt abzuwarten. Nicht unrealistisch ist allerdings die Überlegung, dass die Neuregelung in Nordrhein-Westfalen nach Jahren des Stillstandes endlich auch auf der Bundesebene zu einer überfälligen Novelle des Arbeitszeitgesetzes führt.
Sonntagsöffnungszeiten von Öffentlichen Bibliotheken ermöglichen
Authors: Kappert-Gonther Kirsten
Published: August 2019

Öffentliche Bibliotheken sind notwendige Kultur- und Bildungseinrichtungen, die mit ihren Angeboten die gesamte Bevölkerung erreichen. Mit einem Antrag fordern Bündnis 90/Die Grünen im Bundestag die Bundesregierung auf, die Sonntagsöffnung von Öffentlichen Bibliotheken zu ermöglichen. Gerade sonntagsgeöffnete Bibliotheken können einen wesentlichen Beitrag zur kulturellen Bildung, zum lebenslangen Lernen und zu sozialer Teilhabe und Begegnung leisten.
Die Sonntagsöffnung für Öffentliche Bibliotheken in Nordrhein-Westfalen aus der Sicht des Borromäusvereins
Authors: Schröer Guido
Published: August 2019

Der Schutz des arbeitsfreien Sonntags ist ein hohes Gut. Durch mehr und mehr verkaufsoffene Sonntage wird dieser Schutz aufgeweicht. Bibliotheken stehen aber nicht für Kommerz, es geht nicht ums Einkaufen, es geht um ein wichtiges kulturelles Angebot. Dieses soll auch am Sonntag zugänglich sein. Die Art und Weise ist dabei näher zu bestimmen, nicht alle bibliothekarischen Aufgaben sollen am Sonntag erledigt werden. Bibliotheksmitarbeiter*innen sollen nicht unnötig belastet werden. Ganz ohne Sonntagsdienst wird es aber auf absehbare Zeit auch nicht gehen.

Sonntagsöffnung in Öffentlichen Bibliotheken - oder soll man es lassen?
Authors: Schleiwies Gerald
Published: August 2019

Die Diskussion über die Sonntagsöffnung in deutschen kommunalen Bibliotheken dauert seit 2007 an. In Nordrhein-Westfalen ist nun durch eine politische Entscheidung weitere Bewegung in die Diskussion gekommen. Ein kurzer zusammenfassender Rückblick auf die Diskussion und das Aufzeigen neuer Hürden, die je nach Bundesland und Einrichtung anders ausfallen können. Und die Hypothese: Haben wir nicht wichtigere Themen? Eine kritische Anmerkung.
Die Bibliothek gehört den Bürger*innen - auch und vor allem am Sonntag!
Authors: Leik Tim
Published: August 2019

Seit dem 24. September 2017 ist die Zentral- und Landesbibliothek Berlin, Standort Amerika-Gedenkbibliothek, sonntags geöffnet. Jeden Sonntag finden in den Räumen der Amerika-Gedenkbibliothek zahlreiche Veranstaltungen für Kinder und Erwachsene statt. Die Reaktion der Besucher*innen auf die erweiterten Öffnungszeiten könnte kaum deutlicher ausfallen: Im Durchschnitt kommen sonntags rund 2.000 Besucher*innen in die Amerika-Gedenkbibliothek. Mit der Aktion Offener Sonntag verfolgt die Zentral- und Landesbibliothek Berlin zweierlei: erstens eine Änderung des Arbeitszeitgesetzes und zweitens die Bibliothek als Experimentierraum zu betrachten, um den Ort unter anderem zu einer partizipativen Plattform für die Berliner Stadtgesellschaft (weiter) zu entwickeln.

In the case of Raviart–Thomas finite elements of arbitrary polynomial degree, the resulting error estimator constitutes a guaranteed upper bound for the error and is shown to be local efficient.
Our reconstruction is performed locally on a set of vertex patches.
Inhibitory effect of activin A on IL-9 production by mouse NK cells through Smad3 signaling
Authors: Ma Chunhui , Qi Yan , Liu Haiyan , Wu Chengdong , Cui Xueling , Liu Zhonghui
Published: August 2019

Interleukin-9 (IL-9) is a cytokine secreted by T-helper (Th)9 cells, and activin A can enhance Th9 cell differentiation. However, whether activin A affects IL-9 production by natural killer (NK) cells remains unclear. Herein, we found that not only Th cells, but also CD3−CD49b+NKp46+ NK cells of Balb/c mice produced IL-9. Although activin A promoted IL-9 expression in CD4+ Th cells, it inhibited IL-9 production by CD49b+NKp46+ NK cells in mice. Furthermore, the enzyme-linked immunosorbent assay (ELISA) results showed that mouse NK cells could secrete mature IL-9 protein, and activin A inhibited IL-9 release by NK cells. Additionally, activin A inhibited interferon (IFN)-γ production in splenic NK cells in mice, but promoted IL-2 production, and did not alter the production of IL-10. Western blotting results showed that levels of activin type IIA receptor (ActRIIA), Smad3 and phosphorylated-Smad3 (p-SMAD3) protein increased in activin A-treated splenic NK cells, compared with that in control NK cells. The inhibitory effects of activin A on IL-9 production by NK cells were attenuated in the presence of activin antagonist follistatin (FST) or Smad3 knockdown to NK cells. These data suggest that although activin A up-regulates IL-9 expression in Th cells, it inhibits IL-9 production in NK cells through Smad3 signaling.
Dynamics of an N-Species Gilpin–Ayala Impulsive Competition System
Authors: Wang Libo , Xu Guigui
Published: August 2019

In this paper, we consider an N-species Gilpin–Ayala impulsive competition system. By using comparison theorem, Lyapunov functional, and almost periodic functional hull theory of the impulsive differential equations, this paper gives some new sufficient conditions for the permanence, global asymptotical stability, and almost periodic solution of the model. Our results extend some previously known results. The method used in this paper provides a possible method to study the permanence, global asymptotical stability, and almost periodic solution of the models with impulsive perturbations in biological populations.
Positive Solutions for a Semipositone Singular Riemann–Liouville Fractional Differential Problem
Authors: Agarwal Ravi P. , Luca Rodica
Published: August 2019

We study the existence of multiple positive solutions for a nonlinear singular Riemann–Liouville fractional differential equation with sign-changing nonlinearity, subject to Riemann–Stieltjes boundary conditions which contain fractional derivatives. In the proof of our main theorem, we use various height functions of the nonlinearity of equation defined on special bounded sets, and two theorems from the fixed point index theory.

Authors: Singh Mehtab , Malhotra Jyoteesh
Published: August 2019

In this paper, we report the modeling and simulative investigation of a mode division multiplexing (MDM)-based Radio over Free space optics (RoFSO) transmission system. Two separate 10 Gbit/s–10 GHz information signals are transported successfully over 30 km link range using distinct Hermite Gaussian (HG) modes. Also, the decomposition of distinct modes at the receiver terminal has been reported in this work. Furthermore, the impact of different fog conditions and scintillation effect on the performance of the proposed link has also been discussed in this paper.
A Brief Review on the Methods that Improve Optical Burst Switching Network Performance
Authors: Poorzare Reza , Abedidarabad Siamak
Published: August 2019

In this tutorial, we give an introduction to optical burst switching (OBS) networks and compare different methods that have been given to improve performance of these networks. OBS is an alternative to optical circuit switching and optical packet switching by separating data from control packets and sending them in a different wavelength. OBS networks suffer from an issue based on their bufferless nature, burst contentions. In these networks, when two data bursts are competing on the same wavelength, one of them is dropped and it leads to a significant reduction on the performance of the network. A lot of researches have been done to solve this problem. Some of them are addressed in this paper.

Published: August 2019

Long-haul 16-channel dense-wavelength division multiplexing networks employing two different avalanche photodiode (APD) structures (Si and InGaAs) and positive-intrinsic-negative (PIN) photodetectors are simulated and compared under thermal noise effects for different fiber lengths. The effect of thermal noise level on the transmission quality with a variation of amplifying section length, number of amplifying sections and channel speed is discussed. The impact of thermal noise on the system performance is analyzed by varying input power from −5dBm to 20dBm for both 25 km and 50 km amplifying section at 100 km fiber length. The performance is evaluated for both 5 Gb/s and 10 Gb/s data rates over transmission distances up to 500 km. A comprehensive comparison is developed based on signal-to-noise ratio (SNR), quality factor (Q-factor) and bit error rate (BER). It is found that both APD structures achieve superior performance up to distance of 350 km comparing to PIN photodetectors for 50 km amplifying section. The system provides optimum performance at input power P
in = 10dBm in case of 50 km amplifying section, but then afterwards, the performance is degraded rapidly due to nonlinearities. The results revealed that the worst performance scenario is at 10–18 W/Hz thermal noise in terms of higher BER and lower Q-factor. Finally, the desirable BER of 10–12 is achieved at Q-factor of 6.78 and SNR of 23 dB.

Published: August 2019

Wavelength division multiplexing (WDM) is a very important technique to utilize the bandwidth of optical fiber; multiple channels can be transmitted in the same fiber cable at the same time, and each channel has individual wavelength. At different network node, it’s required to add or drop wavelength, wavelength converter process is a technique responsible for converting the wavelength of signal to other wavelength up or down from the original value. This paper has presented a proposed model to generate inverted and non-inverted wavelength conversion by using single wide band traveling wave semiconductor optical amplifier (WBSOA), based on cross-gain modulation. The investigation of conversion efficiency (η) and quality factor (Q), versus pump power ranged value from −30 to 0 dB m, and input signal power is 0 dB m with data rate 25 Gb/s, are studied for up and down-wavelength conversion, “co-propagation” and “counter-propagation”, respectively. The simulation results indicate that, to get maximum conversion efficiency and maximum quality factor by using single WBSOA, the pump power should be located between −30 to −20 dB m for maximum conversion efficiency and equal to −10 dB m for maximum quality factor, that for up- and down-wavelength conversion, co-propagation and counter-propagation.
Ikonographie und Interaktion. Computergestützte Analyse von Posen in Bildern der Heilsgeschichte
Authors: Bell Peter , Impett Leonardo
Published: August 2019

The last few years have seen an explosion of medieval images in digital form, chiefly as a result of photo-library and manuscript digitisation projects. An entire corpus of images, even selected solely by scene or iconography, becomes an unwieldy object of study by traditional art-historical means. This is even more the case for medieval images, where authorship and dating are often cloudy and unclear, and the image itself is in many cases the first resource for scholarly inquiry.We take the digital image – in particular, the digital image of the body – as our object of study in a wide-ranging computationally-augmented reading of an image-corpus; ours is made up of thousands of depictions of the ‘Annunciation’ and ‘Baptism’, selected not only for their primacy in Christian art but for their dialogical interaction. Our corpus of 6,564 ‘Annunciations’ and 883 ‘Baptisms’, whilst not necessarily representative in density, includes a wide range of stylistic, theological and historical tendencies.We computationally extract not only body images but poses, gestures and interactions. Such a range of gestures allows for a morphological treatment of bodily motifs, whose multi-dimensional, quantitative nature allows us to complicate and problematise iconographic taxonomies, populating the spaces between categories. Finally, our gestural manifolds provide a morphological pointer to dissecting the microtemporalities of the scenes, and their relative dynamics and inconsistencies.
