The Peculiarities of Text/Discourse Deixis in the English Language
Authors: Abdulla Mahmudova Shafagat
Published: March 2020

The text/discourse deixis is found to be used in the English language to express the interpersonal relationships involved between the speaker and listener in conversation. The article explores some peculiarities of text/discourse deixis in the English language. It is noted in the article that while the traditional categories of the deixis are the most obvious examples, there are other types of deixis that are widely available. These categories are for the first time discussed by Fillmore and Lyons. These categories are categories of social deixis and text/discourse deixis. Our article deals with the use of the text/discourse deixis in English. The article also covers discussion of linguistic views of scientists in this field. We think that urgency of the work just lies in the theoretical problems discussed in the article. The article is also of both theoretical and practical importance in the view of learning English and developing the science of linguistics as a whole.
Spontaneity of Speech Errors: A Diagnostic Psycholinguistic Case Study
Authors: Abdulaal Mohammad Awad Al-Dawoody , Abuslema Naglaa Fathy Mohammad Atia
Published: March 2020

The aim of this study is to use speech errors as a verbal means of communication to clarify the psychological aspects of George W. Bush’s character. Bush’s character is chosen for being highly controversial, having received the lowest approval rating in 2008 and the highest approval rating after the September 11 attacks. To achieve the aim of this study, a psycholinguistic approach is adopted in addition to a speech production model set by Dell (1999), and Chang and Griffin (1999). Some of Bush’s spontaneous errors are supposed to be collected, and then categorized from a psycholinguistic perspective and finally analyzed statistically. The main results of the study can be summed in the following points. (a) The phonological and morphological errors, caused by the psychological priming, reveal how much perplexity and confusion Bush has experienced. (b) Bush’s Freudian slips—caused by psycho-physiological factors, such as fatigue, excitement, and distraction—reveal the fact that he is not an open outright president as he represses many thoughts and feelings more than he shows. (c) Bush’s syntactic errors, caused by the improper lexical insertion, reveal his poor linguistic competence; the matter that reveals low intelligence for many psychologists such as Pishghadam and Shams (2012). (d) The economical use of speech disfluencies, caused by problems in the recognition system, reveals that Bush has a tendency of rashness. That is, he may take rapid incorrect decisions that lead to catastrophes.
Utilities Included: Split Incentives in Commercial Electricity Contracts
Authors: Jessoe Katrina , Papineau Maya , Rapson David
Published: March 2020

This paper quantifies a tenant-side “split incentives” problem that exists when the largest commercial sector customers are on electricity-included property lease contracts, causing them to face a marginal electricity price of zero. We use exogenous variation in weather shocks to show that the largest firms on tenant-paid contracts use up to 14 percent less electricity in response to summer temperature fluctuations. The result is retrieved under weaker identifying assumptions than previous split incentives papers, and is robust when exposed to several opportunities to fail. The electricity reduction in response to temperature increases is likely to be a lower bound when generalized nationwide and suggests that policymakers should consider a sub-metering policy to expose the largest commercial tenants to the prevailing retail electricity price.
Least-cost Distribution Network Tariff Design in Theory and Practice
Authors: Schittekatte Tim , Meeus Leonardo
Published: March 2020

In this paper a game-theoretical model with self-interest pursuing consumers is introduced in order to assess how to design a least-cost distribution tariff under two constraints that regulators typically face. The first constraint is related to difficulties regarding the implementation of cost-reflective tariffs. In practice, so-called cost-reflective tariffs are only a proxy for the actual cost driver(s) in distribution grids. The second constraint has to do with fairness. There is a fear that active consumers investing in distributed energy resources (DER) might benefit at the expense of passive consumers. We find that both constraints have a significant impact on the least-cost network tariff design, and the results depend on the state of the grid. If most of the grid investments still have to be made, passive and active consumers can both benefit from cost-reflective tariffs, while this is not the case for passive consumers if the costs are mostly sunk.

Modelowanie procesu korozji siarczanowej w kominie żelbetowym
Authors: Konderla Piotr , Kutyłowski Ryszard , Patralski Krzysztof
Published: March 2020

Kominy przemysłowe, z uwagi na charakter pracy i lokalizację, pracują
w środowisku charakteryzującym się silnym oddziaływaniem korozyjnym na konstrukcje budowlane. Głównym źródłem negatywnych oddziaływań chemicznych są spaliny przepływające przez przewód kominowy, zawierające znaczne ilości związków siarki, które w określonych warunkach mogą wywoływać korozję siarczanową konstrukcji trzonu komina, a w konsekwencji prowadzić do obniżenia nośności i trwałości konstrukcji żelbetowych kominów. Celem pracy była próba jednolitego, możliwie prostego opisu procesu korozji siarczanowej jako superpozycji kilku sprzężonych procesów zachodzących w trakcie pracy komina, a w szczególności: a) przepływu spalin w przewodzie komina; b) dyfuzji jonów siarki w betonie trzonu komina z jednoczesnym tworzeniem się siarczanów; c) postępującej destrukcji betonu trzonu żelbetowego
w wyniku korozji siarczanowej i w efekcie obniżania się nośności konstrukcji komina. Badania konstrukcji in situ są danymi wejściowymi dla powyższych procesów. Rozważania teoretyczne są ilustrowane wynikami analizy wybranego żelbetowego komina przemysłowego odprowadzającego spaliny o dużej zawartości związków siarki.

Strojenie konstrukcji przy obciążeniach cyklicznych
Authors: Gierczak Jan , Ignatowicz Rajmund
Published: March 2020

W prezentowanej publikacji przedstawiono sposób strojenia konstrukcji na przykładzie konstrukcji stropu w Zakładach Spożywczych. Drgania przekazywane na strop pochodziły od przenośnika dwumasowego typu PVK2-9 wywołującego lokalne ponadnormatywne drgania. Opisano metodę identyfikacji szkodliwych drgań oraz sposób ich usunięcia poprzez zastosowanie podpory o zmiennej podatności. Miała ona za zadanie dostrojenie konstrukcji tak, aby znajdowała się poza rezonansem, tzn. aby częstotliwość drgań własnych układu konstrukcyjnego była różna od częstotliwości drgań wymuszonych przez urządzenia [1, 2, 3]. Zaproponowane rozwiązanie zweryfikowano po wykonaniu wzmocnienia przez rejestrację parametrów dynamicznych stropu wibrogramem wymuszenia kinematycznego [1, 2].
The Lithuanian-Polish-Ukrainian Brigade’s development potential in the context of regional security
Authors: Fryc Mariusz
Published: March 2020

Since January 2017 the Lithuanian-Polish-Ukrainian brigade (LITPOLUKRBRIG) is fully operational to influence and shape not only regional security but also international peace out of Europe. Its development potential can contribute to support Ukraine in its current military reform as well as in an accession process to NATO. It can positively impact military competencies, capabilities, and capacities of all founding nations and contribute to a stronger regional identity based on common values, interests, experiences and threats perceptions either. Now is the time for the founding nations to decide whether to keep a status quo of the brigade or to further build its “trademark” upon its strengths and competencies. If they choose the second option, the Brigade has to become more visible and active in the security sphere which leads to the necessity to demonstrate its effectiveness and utility in practice.
The purpose of this article is to answer the questions: where is the development potential of the Lithuanian-Polish-Ukrainian Brigade and how it can be used in the context of strengthening both tripartite cooperation and security in the region. In the introduction, the author collides different perspectives on the future of LITPOLUKRBRIG. In the first part, he argues that the brigade can help Ukraine to join the Euro-Atlantic family. In the second part, he justifies that the brigade can have a positive impact on military capabilities development and the interoperability of the armed forces of all founding states. In the third part, he justifies that the brigade has the potential to shape regional security. In the fourth part, he argues that LITPOLUKRBRIG can contribute to building a stronger regional identity and tripartite cooperation based on common values, interests, experiences and common threat’s perception.

Assessment and Comparison of the Mechanical Properties of Laser Welded Joints in Docol 1200M and Strenx S700MC Steel Alloy Grades Under Impact Loads
Authors: PROCHENKA Paweł , JANISZEWSKI Jacek
Published: March 2020

The article evaluates the strength and ductility of laser butt joints made of 2 mm Docol 1200 M martensitic steel sheets based on the hardness, quasi-static
and dynamic tensile tests. Technological research of laser welding process was carried out on welding cell using IPG fiber – based welding source with 6 kW maximum power. The tests were carried out for parallel and perpendicular orientation of specimens by rolling direction. In addition, the obtained results were compared with the analogous results obtained during the Strenx S700 MC steel tests. Dynamic tests were performed using the tensile split Hopkinson pressure bar technique with strain rates of 103 s-1. The obtained results showed that the strength of Docol 1200 M under dynamic tensile test conditions are similar to the material strength under static tensile test conditions. However, due to the breaking of the specimens in the heat affected zone, the strength of the welded joint is much lower than in base material, which was not observed during the Strenx S700 MC steel tests.

The PILICA Anti-Aircraft Rocket-Artillery System has been developed for the Armed Forces of the Republic of Poland. The PILICA Anti-Aircraft Rocket-Artillery System is composed of: The Command and Control station, the Radiolocating station, six Firing Units along with Artillery Tractors, two Transport Vehicles, and two Ammunition Vehicles. PILICA's task is that of detecting, recognising, and identifying objects, then automatically dividing the tasks and commands for efficient elimination. PILICA’s Firing Unit has autonomous-mode target detection, identification and elimination capabilities (without cooperating with Command and Control) using equipment such as its optoelectronic head and IFF system. In the system operation mode and in cooperation with Command and Control, the Firing Unit and its subsystems ensure the reception of commands/combat tasks in its fire responsibility zone, as well as reporting statuses and the completion of the given combat tasks. Reporting and command reception from the Command and Control station is automated. The Firing Unit can fire using its automatic tracking system, or when operated in manual mode. The Firing unit has been equipped with a portable remote control console, providing the ability to use it remotely. In case of a power supply malfunction in the Firing Unit, it is possible to use it entirely manually, with the use of artillery weapons. The Firing Unit is equipped with a stabilised, optoelectronic day-night head that enables it to work independently of the weapons when it comes to observation and detecting, as well as identifying, objects. The head constitutes not only an element of the guidance system, but also a source of information for the entire System, as the data on the detected and observed objects is exchanged within the entire command network. PILICA is equipped with an unique formation and training system, providing capabilities for training teams on real equipment, with the use of a virtual simulation management system employing the DIS protocol.
Sua queda é sua dignidade: Eric Weil e Agostinho sobre a “felix culpa”
Authors: Perine Marcelo
Published: March 2020

O artigo propõe uma aproximação entre a concepção agostiniana do pecado original e a concepção weiliana da atitude da fé na categoria Deus da Lógica da filosofia. Na tradição latina, Agostinho, a quem se atribui equivocadamente a fórmula “felix culpa”, situa-se na origem de uma concepção do pecado original que será determinante na concepção de ser humano da antropologia e da moral cristãs. Na Lógica da filosofia de Eric Weil (1904-1977), na exposição da atitude da fé a que corresponde a categoria filosófica Deus, a expressão “sua queda é sua dignidade” parece fazer eco à fórmula supostamente agostiniana. A presente reflexão parte da tese de que a leitura weiliana de Santo Agostinho subjaz à formulação da categoria Deus da Lógica da filosofia, o que permitiu a Weil formular adequadamente a atitude do crente. O artigo sustenta que as linhas fundamentais da concepção de ser humano subjacente à atitude da fé na Lógica weiliana concordam com a concepção antropológica agostiniana decorrente da sua teologia do pecado das origens. Finalmente, o texto sugere que a concepção antropológica agostiniana está presente em filigrana na concepção weiliana do ser humano como finito e livre, claramente de inspiração kantiana.
O Capelão como mediador: revisão integrativa
Authors: Gama Eliane Florencio , Jarra Thamires Fiorentino
Published: March 2020

As mudanças observadas na estrutura sociocultural desde os tempos bíblicos até os dias atuais determinaram o desdobramento das diferentes áreas de atuação da Capelania/Aconselhamento, tais como nas áreas Hospitalar, Militar, Carcerária, Empresarial, dentre outras. Apesar dessa diversidade de áreas de atuação pode-se destacar uma situação comum: os conflitos interpessoais. Uma das possibilidades de intervir em situações de conflito é a Mediação informal, que se caracteriza pela atuação de um terceiro facilitador, que auxilia na solução amigável de conflitos. O objetivo do presente estudo foi quantificar, listar e analisar a literatura sobre a prática da Mediação Informal na Capelania/Aconselhamento. Foi utilizado o método da revisão integrativa, buscando dados nas seguintes bases eletrônicas Portal de Periódicos da CAPES; Scientific Eletronic Library online-Scielo; Science Direct e Google Acadêmico. Apenas seis artigos apresentaram informações sobre a elaboração de programas e estratégias de mediação de conflitos no âmbito carcerário, corporativo e hospitalar por iniciativa de serviços ou setores de Capelania. Além disso chama a atenção que em apenas uma dessas iniciativa houve um preparo específico dos capelães para mediação, realizado por uma ONG canadense que educa, treina e equipa nos moldes da justiça restaurativa, com particular atenção a área da capelania.
Os sentidos da magia: práticas rituais, sacerdotes e clientes nos terreiros de Macapá
Authors: Lima Lorran
Published: March 2020

A presente dissertação articula-se a partir de três dimensões: a história das religiões afro-brasileiras no Amapá, a concepção sobre magia com base em rituais oferecidos enquanto serviços religiosos, e a relação entre clientes e o terreiro, assim como a transição desses para família de santo. Propondo uma análise sobre os sentidos acionados e produzidos a partir da noção de magia nas religiões afro-brasileiras a fim de observar como é percebida e como são caracterizadas as práticas rituais, levando em consideração os trabalhos atrelados à busca de soluções de problemas como: relacionamento, finanças e saúde. A pesquisa etnográfica foi desenvolvida em terreiros da capital do estado do Amapá, Macapá. No entanto, o caráter etnográfico permeia dados que vão além do recorte dos terreiros, ao apresentar, também, a trajetória religiosa dos sacerdotes assentada em suas memórias. A pesquisa possibilita a compreensão de como sacerdotes e clientes interseccionam o entendimento sobre as práticas rituais afro-religiosas defendidas enquanto magia, atribuindo a eficácia e eficiência dos ritos direcionados para diversos fins.

Uma peregrinação advaita ao encontro do outro: o diálogo inter-religioso na obra de Raimon Panikkar
Authors: Grassi Rita Macedo
Published: March 2020

Raimon Panikkar (1918-2010), teólogo e filósofo, nascido em Barcelona, de família cristã-hindu, foi um dos principais expoentes do diálogo inter-religioso. Destaca-se, neste contexto, sua expressão que se tornou célebre: parti cristão, me descobri hindu e retornei budista, sem jamais ter deixado de ser cristão. Em meu retorno, me descobri um melhor cristão. Para entendê-la, compreendemos ser fundamental adentrar o sentido de advaita (adualidade). A forma como a perspectiva védica do advaita está inserida em sua obra e constitui em recurso para a sua concepção do diálogo inter-religioso é o tema principal desta pesquisa. O autor desenvolveu importantes conceitos ao longo de sua obra e podemos identificar não só uma influência, mas uma referência clara à tradição hindu e, mais propriamente, à perspectiva advaita, tantas vezes mencionada por ele e que identificamos como uma espécie de fio condutor ou de fator explicativo para muitas de suas teorias. Esta pesquisa procura investigar de que forma o advaita se constitui em caminho de construção do diálogo inter-religioso nas obras de Panikkar. Para tal, contextualizamos a perspectiva advaita nas origens do Hinduísmo e a sua utilização por parte do autor, a partir de uma análise crítica do pensamento filosófico ocidental, em sua experiência mística, também definida por ele como experiência da Vida. Analisamos suas teorias da visão trinitária e cosmoteândrica, baseadas na Trindade cristã, o seu conceito de cristologia nomeado de cristofania e o desenvolvimento de uma atitude pluralista, que servirá como base para o diálogo inter-religioso em sua obra, a partir do paradigma pluralista da Teologia do Pluralismo Religioso. E identificamos o advaita na construção do que ele entende por diálogo intra-religioso, o encontro do outro em si mesmo, através do que denomina amor advaita. Uma peregrinação que acontece na interioridade do ser humano, paralelamente ao diálogo inter-religioso. Trata-se de uma pesquisa teórica, através de uma perspectiva metodológica crítico-analítica, tendo em vista a sua aplicação no diálogo inter-religioso, embasadas na bibliografia de Panikkar, mas também na de alguns autores que dialogam, criticam e/ou servem como referência para ele.

Theory-building: working the theory-data spectrum
Authors: Engler Steven Joseph
Published: March 2020

This article illustrates some implications of the view that data, theory and methods should be treated as a matched set. They are inseparable companions, equally essential parts of processes of scholarly research and dissemination. When we focus on one of these dimensions, the others are always implicit. When focus on all of them, our work is more complete, consistent and defensible. This contribution to this special issue highlights the value of focusing more explicitly on the inter-relations between all four levels of scholarly work.

Published: March 2020

In the last few years, Twitter has been used to understand several real world events such as political elections, civil conflicts, NFL games, to name a few. Motivated by these many examples we asked ourselves, what does Twitter reveal about the 2014 FIFA TM World Cup? In this paper we (i) analyze the frequency of tweets to show how support evolves during the tournament, to distinguish traditional teams from underdogs, and to show that we can identify important events during matches. Moreover, (ii) we applied clustering techniques to discover similarities on supporters behavior (tweets) that allowed us to infer countries' supporters worldwide. Lastly, (iii) for each match we created cartograms to express the volume and the level of polarization of supporters.

Educational Social Network Group Profiling: An Analysis of Differentiation-Based Methods
Authors: Gomes João Emanoel Ambrósio , Prudêncio Ricardo
Published: March 2020

Social media communities are usually formed by similarities among users. In educational social networks, several factors propitiate the user group generation, e.g. share the same academic environment or interested in common curricular. In order to explain the group formation resulted from educational social network, we applied two group profiling methods based on differentiation. Wilcoxon rank-sum test and PART rules algorithm were applied to a dataset available, the OJE educational social network. The performed experiments showed that the methods were effective to group profiling generation, characterizing 81.81% and 100% of groups, respectively.
Life Event Detection using Conversations from Social Media
Authors: Moyano Luis , Cavalin Paulo , Miranda Pedro Paiva
Published: March 2020

In this work, we explore the possibility to detecting life events from Social Media by means of machine learning classification algorithms. One important difficulty of this kind of detection task is that, typically, Social Media posts are quite short, and there is not much context provided. This lack of context usually implies strong ambiguity leading to poor classification performance. Here, we propose the use of conversations as a means to augment context and improve classification performance. We evaluate single-post vs. conversation classification performance and compare different models for the conversations classifier. Finally, we describe the performance of the different classifiers in a large data set with 20,000 posts.

Published: March 2020

A separação entre estrelas e galáxias é fundamental para estudos galácticos e cosmológicos. Para fontes tênues, o limiar entre ser pontual e extenso fica confuso, dificultando o processo de classificação. O problema se agrava pelo grande volume de dados envolvido em levantamentos como o Dark Energy Survey (DES) e futuramente no Large Synoptic Survey Telescope (LSST). Nesse cenário, o LSST vai varrer o céu inteiro a cada três dias identificando milhões de fontes. Assim, a busca por métodos e processos que realizem a classificação com eficiência e acurácia é fundamental para que a comunidade de astronomia consiga escalar a sua capacidade de analisar os dados do LSST. Visando a preparação para esse contexto, este trabalho propõe a elaboração de um processo exploratório para classificação de estrelas e galáxias baseados na análise de catálogos treinados a partir do levantamento COSMOS.

Published: March 2020

Historicamente repetições adjacentes tem sido consideradas como DNA não funcional ("lixo"), em grande parte devido ao fato de não haver correlação entre seu conteúdo a complexidade e de um organismo. Diferentes trabalhos tem demonstrado que a ocorrência destas repetições em regiões codificantes e promotoras não é aleatória: genes que contêm repetições em série são enriquecidas em classes funcionais específicas. Este trabalho teve como objetivo desenvolver um pipeline para identificação e armazenamento de repetições adjacentes.

Eventos ambientais extremos afetam a vida de milhões de pessoas. As secas encontram-se nesta categoria. Embora não se possa impedir que este tipo de evento ocorra, a previsão de sua ocorrência possibilita mitigar parte do dano resultante. Uma das variáveis importantes para identificação de ocorrências de secas é a temperatura de superfície do mar (TSM). Este trabalho apresenta um modelo baseado em Redes Neurais para previsão de TSM do Oceano Atlântico Tropical. O modelo é constituído por dois workflows. O primeiro workflow realiza o ajuste do modelo de previsão, enquanto que o segundo realiza a previsão propriamente dita. Os experimentos preliminares apresentaram resultados positivos e apontam para oportunidades de refinamento de modelos tanto para horizontes de previsão de curto prazo como de longo prazo.
Evaluating a Representational State Transfer (REST) Architecture
Authors: Costa Bruno , Pires Paulo
Published: March 2020

The use of Representational State Transfer (REST) as an architectural style for integrating services and applications brings several benefits, but also poses new challenges and risks. Particularly important among those risks are failures to effectively address quality attribute requirements such as security, reliability, and performance. An architecture evaluation can identify and help mitigate those risks. In this work we present guidelines to assist architecture evaluation activities in REST-based systems. These guidelines can be systematically used in conjunction with scenario-based evaluation methods to reason about design considerations and trade-offs. This work also present the results of a survey conducted with industry specialists who have performed architecture evaluations in real world REST-based systems in order to gauge the suitability and utility of the proposed guidelines.

Authors: Crepaldi Bruno , de Souza Cid , de Rezende Pedro
Published: March 2020

Considerado uma variação do problema da galeria de arte, o problema do posicionamento de antenas trata da localização do menor número de antenas requerido para determinar se uma pessoa está dentro ou fora da galeria. Cada antena propaga uma chave única dentro de um ângulo específico de transmissão, e o conjunto de chaves recebidas em um dado ponto deve ser suficiente para decidir se ele pertence ou não ao polígono que representa a galeria. Para verificar esta propriedade de localização, uma fórmula Booleana deve ser produzida junto com o posicionamento das antenas. O problema do posicionamento natural de antenas é NP-difícil. Nesta dissertação, apresentamos um algoritmo exato baseado em programação linear inteira e propriedades geométricas para resolvê-lo. A eficiência do algoritmo é certificada por resultados experimentais que compreendem as soluções ótimas de 720 instâncias, incluindo polígono com buracos de atá 1000 vértices, calculadas em menos de seis minutos em um computador desktop padrão.
Modelos de Disponibilidade para Nuvens Privadas: Rejuvenescimento de Software Habilitado por Agendamento de Migração de VMs
Authors: de Melo Matheus , Maciel Paulo
Published: March 2020

Confiabilidade e disponibilidade são alguns dos principais desafios para administradores migrarem suas aplicações para ambientes de computação em nuvem. Nesse contexto, o envelhecimento de software surge como um problema potencial, pois afeta diretamente a confiabilidade do sistema através de uma degradação gradual e de difícil detecção. Essa dissertação traz um conjunto de modelos analíticos para avaliação de disponibilidade em ambientes de computação em nuvem privados com um mecanismo de rejuvenescimento de software suportado por migração de máquinas virtuais. O principal propósito é propor agendamentos adequados de migrações para maximizar a disponibilidade do ambiente. O estudo foi conduzido de modo a fortalecer os modelos finais, sendo assim conduzidos experimentos em plataformas reais prévios para servir de insumo aos modelos finais. Dentre as contribuições dadas pelo trabalho destacam-se: metodologia para validação de modelos de disponibilidade, metodologia para condução de experimentos de envelhecimento de software, modelos analíticos para avaliação de disponibilidade em nuvens privadas considerando aspectos de envelhecimento e rejuvenescimento de software.
Illumination Inconsistency Sleuthing for Exposing Composition Telltales in Digital Images
Authors: Carvalho Tiago , Pedrini Hélio , Rocha Anderson
Published: March 2020

Images are powerful communication tools. Due to this power it is often worrisome when image manipulations come into play allowing forgers to deceive viewers, change opinions or even affect how people perceive reality. Therefore, it is paramount to devise and deploy efficient and effective forgery detection techniques. From all types of image forgeries, composition images (forgeries using parts of two or more images) are of particular interest. Among different techniques for spotting forgeries, image illumination inconsistencies are the most promising. This work builds upon the hypothesis that “image illumination inconsistencies are strong and powerful evidence of image composition” and presents four original and effective approaches to detecting image forgeries. The first method explores eye specular highlight telltales to estimate the light source and viewer positions in an image. The second and third approaches explore the color phenomenon called metamerism, whereby two colors may appear to match under one light source but appear completely different under another one. Finally, the last approach relies on user’s interaction to specify 3-D normals of suspect objects in an image from which the 3-D light source position can be estimated. These approaches represent important advances, which certainly will be a strong tool for forensic analysts against image forgeries.
Automated Behavioral Testing of Refactoring Engines
Authors: Soares Gustavo , Gheyi Rohit
Published: March 2020

Refactoring is a transformation that preserves the external behavior of a program and improves its internal quality. To help developers in this task, current IDEs, such as Eclipse and NetBeans, automate a number of refactorings. However, implementing refactorings is a complex task, and so, even mainstream IDEs contain critical bugs. We propose an automated approach for testing of Java refactoring engines. Its key components are: JDOLLY, a Java program generator, and SAFEREFACTOR, a program for checking behavioral changes. The technique uses JDOLLY to generate programs as test inputs. For each generated program, it applies the refactoring by using the engine under test, and uses oracles based on SAFEREFACTOR to evaluate the correctness of the transformation. In the end, it classifies the failures into distinct bugs. We have evaluated this technique by testing up to 10 refactorings from Eclipse, NetBeans and the JastAdd Refactoring Tools. Our technique tested 153,444 transformations, and identified more than 100 bugs, which were reported to engines’ developers. They accepted most of them, and already fixed 35 bugs.
Graph Laplacian for Spectral Clustering and Seeded Image Segmentation
Authors: Casaca Wallace , Taubin Gabriel , Nonato Luis Gustavo
Published: March 2020

Interactive segmentation methods have gained much attention lately, specially due to their good performance in segmenting complex images and easy utilization. However, most interactive segmentation algorithms rely on sophisticated mathematical formulations whose effectiveness highly depends on the kind of image to be processed. In fact, sharp adherence to the contours of image segments, uniqueness of solution, high computational burden, and extensive user interaction are some of the weaknesses of most existing methods. In this thesis we proposed two novel interactive image segmentation techniques that sort out the issues raised above. The proposed methods rely on Laplace operators, spectral graph theory, and optimization schemes towards enabling highly accurate segmentation tools which demand a reduced amount of user interaction while still being mathematically simple and computationally efficient. The good performance of our segmentation algorithms is attested by a comprehensive set of comparisons against representative state-of-the-art methods. As additional contribution, we have also proposed two new algorithms for inpainting and photo colorization, both of which rely on the accuracy of our segmentation apparatus
Danebrog gegen Hakenkreuz
Authors: Bath Matthias
Published: March 2020

Das Buch „Danebrog gegen Hakenkreuz“ gibt dem an Dänemark und an Geschichte interessierten Leser einen Überblick über den dänischen Widerstand gegen die deutsche Besatzungsmacht, der aus der Bevölkerung heraus geleistet wurde. Dabei gilt die Aufmerksamkeit des Autors vor allem den jungen Menschen, die sich für Freiheit und Demokratie und gegen die Besetzung und Fremdbestimmung ihres Landes einsetzten. Damit widmet sich die Publikation einem wichtigen Aspekt im Verhältnis der beiden Nachbarländer. Denn während aus Sicht der meisten Deutschen das deutsch-dänische Verhältnis inzwischen von Tourismus und idealer Nachbarschaft geprägt ist, existiert in der dänischen Landespsyche durchaus noch Angst vor dem Nachbarn im Süden, der nicht nur größer und bevölkerungsreicher ist sondern zudem noch in den letzten drei Kriegen Dänemarks dessen Gegner war. Über Ereignisse in Dänemark während des Zweiten Weltkrieges ist in Deutschland bisher nur wenig bekannt. Wer verstehen will, wie tief das Trauma der Besetzung eines Landes sitzt, das von den Deutschen lediglich als Nebenschauplatz wahrgenommen wurde, findet in „Danebrog gegen Hakenkreuz“ gut recherchierten und verständlich dargelegten Lesestoff.
Landschaftsgeschichte Norddeutschlands
Authors: Behre Karl E.
Published: March 2020

Norddeutschland ist vielfältig: Nordsee, Ostsee und das weite Hinterland der Alt- und Jungmoränengebiete von der Ems bis an die Oder bilden ganz unterschiedliche Natur- und Lebensräume. Wie sie entstanden sind und was der Mensch in den vergangenen Jahrtausenden aus ihnen gemacht hat, schildert dieser Band. Mit der Einführung von Ackerbau und Viehhaltung in der Jungsteinzeit begann die Entwicklung der Kulturlandschaft, die in der Folgezeit zu immer stärkeren Umweltveränderungen führte. Seit dem Mittelalter wurden dann große Landschaftsteile buchstäblich ausgeplündert. Die Marschen wurden besiedelt und bedeicht, die Moore kultiviert und die Waldverwüstung auf den Altmoränen führte zu riesigen Heideflächen, während die besseren Jungmoränenböden vielfach zur Beackerung genutzt wurden. Beschrieben werden neben der Landwirtschaft auch die frühen Industrien, die die Landschaft mit geprägt haben.

Das Buch ist von sachkundiger Hand in einem kompakten und informativen Text geschrieben und mit zahlreichen farbigen Abbildungen illustriert. Dabei sind die neuesten Forschungsergebnisse berücksichtigt. Wer als interessierter Laie, Student oder Lehrender Fragen zur Geschichte der Natur- und Kulturlandschaft hat, findet hier die Antworten.
