Manevi Danışmanlık ile Hümanist Psikoloji Arasındaki İlişki
Authors: NURAL Ayşe , TOSUN Ülkü
Published: June 2023

Tarihsel olarak Orta Çağdan beri uygulanmakta olan manevi danışmanlık, bireyin psikolojik iyilik halinin devam ettirilmesi sürecinde manevi yöne vurgu yaparak alternatif çözüm yolları sunmaktadır. Bu konuda ilk çalışmalar, İslam dışındaki dinlerde ve özellikle Hıristiyanlıkta başladığı için bu dinlerle ilgili kültürel özellikleri de yansıtmaktadır. Ülkemizde son yıllarda gelişmeye başlayan manevi danışmanlık için toplumumuzun din ve kültür anlayışıyla uyumlu modellere ihtiyaç vardır. Manevi danışmanlık; sıcak, samimi ve güven içeren bir danışmanlık sürecidir ve benzer özellikler, varoluşsal kaygılara ve insanın anlam arayışına dayanan hümanist psikoloji yaklaşımında da görülmektedir. Bu ikisi arasında, bazılarının içeriklerinde benzerlikler bazılarında da farklılıklar görülmesine rağmen kavramsal olarak örtüşmektedir. Ortak unsurlarının ortaya çıkarılabilmesi amacıyla her iki danışmanlık alanı; özellikleri, tarihsel gelişimleri, vurguladıkları alanlar ve çeşitleri açısından ayrı başlıklar altında incelenmiştir. Böylece çalışmanın amacını, danışanı merkeze alan ve koşulsuz kabul gösteren hümanistik psikolojinin Müslümanlık inancı temelindeki manevi danışmanlıkla bağlarının incelenmesi oluşturmuştur. Literatürde, çeşitli psikolojik kuram ve ekollerle bağlantısı incelenen manevi danışmanlık kuramının, kişi merkezli danışmanlık sürecine odaklanan hümanist psikoloji yaklaşımları ile karşılaştırmalı olarak incelendiği bir çalışmanın olmaması, bu çalışmanın gerekçesini oluşturmuştur. Çalışmada kavramların farklı yönlerinin incelendiği, değerlendirildiği, literatür kaynaklarının derlendiği çalışma usulü takip edilmiş olup konu derinliğinin anlaşılması bakımından geçmiş-şimdi-gelecek arasındaki bağlantıların ve çıkarımların yapılmasında ve aktarılmasında etkili bir model olan hermenötik tarama modeli kullanılmıştır. Manevi danışmanlık ve hümanistik psikoloji yaklaşımlarının benzerlik ve farklılıklarının ele alındığı sonuç bölümünde ise hem isimleri hem de içerikleri açısından benzerlikler bulunan konular şunlardır: Koşulsuz olumlu kabul, insanın önemi, iyilik hali ve anlam arayışı. İsimleri örtüşmekle birlikte içeriklerinin göreceli olarak farklı olduğu konular ise şöyledir: İnsanın özgürlüğü ve özgür irade, ahlak ve sorumluluk, kötülük, dogma ve diyalektik bakış. Sonuç olarak, her iki danışmanlık yaklaşımının da insan unsuruna ve manevi ögelere odaklanmış olmaları nedeniyle kültürümüzle de uyumlu görülen hümanistik psikoloji yaklaşımlarındaki yapılandırılmış danışmanlık süreçlerinin manevi danışmanlık görüşmelerinde kullanılması, danışanlar için yararlı ve süreçler açısından kolaylaştırıcı olacağı öngörülmektedir.

Manevi Danışmanlık ve Rehberlik Perspektifinden Tanrı Tasavvurları ve Varlık Aşamaları Üzerine Psiko-Teolojik Analizler
Authors: KARLIK Zeynep
Published: June 2023

Bu makalenin amacı, manevi danışmanlık ve rehberlikte danışanın zorlu yaşam olaylarıyla başa çıkmasında, anlam arayış süreçlerinde ve iyi oluş düzeylerini yükseltmede Tanrı tasavvuru ve varlık aşamalarının kullanıldığı bir yaklaşım önermektir. Bu yaklaşımla danışan daha latif hallere geçtikçe ve farkındalık kazandıkça Tanrı karşısındaki konumu değişecek ve ilahî isimleri daha yüksek derecede yansıtabilecektir. Bu ise danışanı birlik bilincine götürerek evrende iyi veya kötü olarak ayrımın olmadığı bir bilinç seviyesine çıkaracaktır. Bu bağlamda makale, Tanrı tasavvuru ve varlık aşamaları psiko-teolojik olarak analiz edilerek değerlendirilmekte ve manevi danışmanlık ve rehberlik uygulamalarına kuramsal katkı sağlayacak teorik bir çalışma sunmayı hedeflemektedir. Tanrı tasavvuru, danışanlar arası farklılık gösterdiği gibi inançlara göre de değişiklik arz etmektedir. Bu nedenle bu çalışmada İslam düşüncesi ekseninde Allah tasavvuru modeli önerilmektedir. Tanrı’yı tasavvur ettikten sonra danışanın O’nun karşısındaki konumu varlık aşamalarıyla ifade edilmektedir. Değişen ve gelişen anlamını taşıyan varlık kavramı tüm canlılarda ‘ışık’ı yansıtabilme potansiyeli ile doğru orantılı olmaktadır. İnsanda bu potansiyel en yüksek aşamaya ulaşabilmekte ancak bunun için düşünsel veya davranışsal olarak Tanrı ile arasına koyduğu perdeleri kaldırması gerekmektedir. Bu aşamalar, bilinç aşamaları olarak ilk defa Assagioli tarafından psikoloji ile tasavvufî ögeler birleştirilerek yorumlanmıştır. Frager’ın nefs aşamaları ile bu sınıflandırmayı örtüştürmesi sonucunda psikoloji ve teolojinin ortak oluşturduğu bir metot ortaya çıkmıştır. Bu metoda göre danışan yaşamdaki dünyevî zevkleri sorgulatan bir uyanma deneyimi yaşadığında alt bilincine ışık tecelli etmeye başlamaktadır. Bu tecelliler, danışanın olgunlaşma yolculuğunda eşlik ederek onu ‘ışık’ ile birlemeye götürmektedir. Ancak burada önemli olan konu, danışanın düşünsel ve davranışsal perdelerini kaldırması gerektiğidir. Bilinci değişen danışanın hali değişerek tecelli alma kapasitesini de değiştirecektir. Tanrı’dan gelen tecelliler İbnü’l Arabi’nin ilahî isimler teorisi ile yorumlanarak danışanın halinin tecelli eden ilahî isimlerden kaynaklandığı öne sürülmektedir. Makalede, danışanın zor yaşam olaylarıyla başa çıkmasında, anlam arayış süreçlerinde ve iyi oluş düzeyini yükseltmede Tanrı tasavvuru ve varlık aşamalarının manevi danışmanlık sürecine dâhil edilmesiyle olumlu katkı sağlanacağı sonucuna ulaşılmıştır.

Opera which Involves Dance, or Ballet which Involves Singing: Comédie Lyrique on the Stage of the Royal Academy of Music in Paris
Authors:   Moscow State Tchaikovsky Conservatory, Safonova Alexandra A.
Published: June 2023

The article is devoted to the receptivity of the premiere performances of André Grétry’s musical comedies on the stage of the Paris Royal Academy of Music in the 1780s. Our attention becomes focused on materials of critical reviews in the French press, which became public responses to the premiere productions and testimonies that the ballets in such performances not merely played a significant role, but frequently became the main causes of enthusiastic ovations by audiences. In the 1780s, Grétry sought to revive the “genuine comedy” in the vein of Molière on the stage of the Royal Academy of Music in Paris. Obviously, in such performances the ballet was given an important role, since, according to the composer, the French had a natural inclination towards this art. Notably, the first comedy “La Double épreuve ou Colinette à la Cour”, notwithstanding its chilly reception, received its ultimate recognition particularly for its pantomimic and dance numbers. They accounted for about a third of the entire composition and, according to the critics, they were “well grouped and beautifully written, creating visual effects full of motion and variety”. “L’Embarras des richesses”, “La Caravane du Caїre”, “Panurge dans l’isle des Lanternes” not only became successful performances highly appreciated for their musical merit, but also significantly enriched the French ballet, including both the pantomime and dance comprising it. The quantity of divertissements and the number of characters involved in them captured the imaginations of the audiences. These were ceremonial productions of comedies with through dramatic development, as well as luxuriant scenic decorations and costumes. they brought together the efforts of the best singers, dancers, artists, costumers and creators of theatrical machinery. The subtle, sparkling humor, the pleasant music striking by its variety, the finesse of details and small touches also found their refraction in ballet scenes. Their colorfulness and innovativeness pleased the exacting Parisian public to such a great degree that they were applauded enthusiastically not only at the premieres, but also during the repeated performances. Eloquent testimonies of this were imprinted in the French press of the time.
Ballet in the Theaters of the Radziwill Princes in the 18th Century
Authors:   Gnesin Russian Academy of Music, Patoshina Anastasia Yu.
Published: June 2023

The appearance of the first ballet productions and the emergence of professional education for dancers on the territory of Belarus in the 18th century is associated with the activities of the theaters of the magnates — the wealthiest representatives of the highest nobility of the Grand Duchy of Lithuania, Russia and Zhmud, which included present-day Belarusian lands. The theater stages, equipped with complex mechanisms and decorations for creating a variety of sound and visual effects, were where the leading choreographers and dancers of their time worked. The most durable and large-scale activities were those of private theaters created and functioning at the expense of the ‘uncrowned kings’ of the Grand Duchy of Lithuania, the princes Radziwiłłs. The representatives of this family demonstrated sincere interest in art and made their courtyards the center of cultural life and artistic education of their time. To teach the art of the ballet to their own children, people close to the court and cadets of the ‘Knight’s Academy’ created by the Radziwiłłs based on the model of the Saxon educational institution for the military, the princes invited famous professional dancers from France and the Italian kingdoms to work. In order to form permanent dance troupes at their theaters in Slutsk and Niasviž, the Radziwiłłs established ballet schools. The heyday of the art of ballet on the theater stages belonging to the Radziwiłłs dates back to 1777–1790. During this period, along with choreographers from European countries, Belarusian dancer Antony Loiko began engaging himself in productions of ballet divertissements and interludes. Student of ballet reformer Jean-Georges Noverre, Francesco Caselli staged several ballet performances with detailed dramatic plots, one of which was Orfeusz w piekle (Orpheus in Hell) to the music of the German composer and leader of the Niasviž Chapel, Jan Dawid Holland. The activities of the theaters belonging to the Radziwiłłs in the 18th century were of great significance for the development of the art of dance, as well as education for people of different social strata. Because of the latter’s personal participation in performances, not only representatives of the nobility, but also peasants, bourgeois and soldiers were introduced to classical European music and ballet. Children who successfully completed their studies at schools with leading European choreographers acquired a profession that allowed them to later work in different theaters and provide themselves with a comfortable existence.
Can Journalism Be Danced? From the History of 19th Century British Ballet
Authors:   Gnesin Russian Academy of Music, Agisheva Yulia I.
Published: June 2023

In 1898 the ballet titled The Press was staged at the Empire Theatre in London. Choreographer and producer Katti Lanner, composer Leopold Wenzel and costume designer C. Wilhelm made a nontrivial attempt to transfer the sphere of journalism into the space of dance. Austrian dancer, pedagogue and choreographer Katti Lanner went down in the history of ballet theatre not only as the first woman who made a career as a choreographer but as the inventor of a new genre — the ‘entertaining revue’. The choreographer’s productions were often based on modern plots. Besides the ballet The Press, Lanner’s artistic output included such ballets as The Sports of England, The Paris Exhibition and others. The music director of the Empire Theatre, Italian composer Leopold Wenzel was Lanner’s collaborator in a number of her productions. Wenzel was the composer of art songs, orchestral works, operas and music for ballet. Scenographer C. Wilhelm, who supplements this triumvirate, was one of the most successful and prolific theatre designers of that time. At the same time, most information about the creators and the production of the ballet The Press is almost absent in academic scholarly literature. This article examines the features of scenography and music of the ballet, its place and role in the history of the ballet theatre of Great Britain in the 19th century. The attempt is made to reconstruct some of the elements of the ballet. Of no small importance is the inverse response – critical materials of the main “protagonists” of the ballet on the pages of British newspapers from 1898 from archival sources, as well as rare pictures. The question of whether or not it is possible to recount about journalism in the language of dance is one of the most crucial questions raised in the article.
E.K. Malinovskaya and Ballet
Authors:   Herzen State Pedagogical University of Russia, Gordeev Petr N.
Published: June 2023

Elena Konstantinovna Malinovskaya (1875–1942) played a significant, albeit, at a first glance, not a particularly distinguishable role in the history of the Russian stage. After the revolution, she directed a number of Moscow State (which held the appellations of Academic starting from 1919) theaters until 1924, during the years 1930–1935 she was the director of the Bolshoi Theater. For eleven years, Malinovskaya's personality, artistic views and administrative tactics influenced in various degrees the development of one of the two largest ballet companies in the country. She was compelled to take into account the tastes of high-ranking “curators” of the theater (Anatoly Lunacharsky, Avel Enukidze et al.), to comply with the demands of a powerful trade union organization, adapt to Communist Party censorship, struggle against the desires of choreographers and dancers for tours abroad, which frequently turned into one–way trips. Malinovskaya had to deal with, and not unsuccessfully, not only management of theaters, and also provide for the living conditions of artists. On the basis of materials introduced into scholarly circulation for the first time (first of all, from Malinovskaya's extensive personal funds in the Russian State Archive of Literature and Art and the A.A. Bakhrushin State Central Theater Museum), this article examines the complex relationships of Elena Malinovskaya, the Bolshoi Theater Ballet Troupe and various public figures from the world of art and politics, involved in ballet in various degrees, during the years 1918–1935. Overall, Malinovskaya's artistic activities have been evaluated highly in the history of Russian ballet.
“The Riddle” about the Centre in the Fifth Movement of Anton Webern’s Cantata op. 31
Authors:   Gnesin Russian Academy of Music, Gerver Larisa L.
Published: June 2023

The article presents an analytical commentary of Anton Webern’s elucidation of the form in Freundselig ist das Wort (the fifth movement of his Cantata opus 31): “In the centre are the words: 'Weil er am Kreuz verstummte <...>” (from a letter to Hildegard Jone dated 25 July, 1942). Although the boundaries of the phrase about the Cross are clearly marked by double barlines in the musical score, it is not easy to understand exactly what Webern meant. Kathryn Bailey, the author of an article about the Cantata Opus 31 and a book about Webern's serial works, has labeled his statement about the centre as “somewhat imprecise to say the least” and the bars encompassing it “a riddle.” Responding to these evaluations and drawing on Bailey’s research — primarily, the signs of the central symmetry in the serial canon Freundselig ist das Wort demonstrated by her — the author of this article offers her own version of the solution to the question of the centre. An analysis from the position of metrotectonicism shows that, first, the phrase about the Cross does not present the centre in a strict sense, although it is located at the centre of the five sections of Freundselig ist das Wort, and, second, that a compositional centre does, indeed, exist here. This is demonstrated by the peculiarly shaped ending to the phrase about the Cross, which corresponds to the notion of a “central cadence,” which, according to Georgy Konyus, is “a sort of knot binding the identical or similar constructions placed on either side of it,” and is situated at an equal distance from the beginning and final points of the form.

Supporting software evolution actions with process mining
Authors: Calegari Daniel , Delgado Andrea
Published: June 2023

There are several forces driving software evolution. One is the business process (BP) misalignment, i.e., when the behavior of the information systems supporting the BPs, or its users, is not aligned with the intended behavior of the BPs identified during the requirement engineering phase. Process Mining (PM) is an essential strategy for BP alignment evaluation. Nevertheless, PM initiatives do not usually focus on connecting BP alignment misfits with concrete software requirements for software evolution. This paper provides initial insights into how PM can support software evolution actions by considering research questions posed during a PM initiative. We exemplify this idea by analyzing administrative procedures within an Electronic Document Management System, providing action guides for its evolution obtained from the PM initiative.

Published: June 2023

The software industry is in continuous evolution, forcing developers to quickly adapt to new requirements to catch up with the latest trends. A clear example is the huge demand for web-based APIs to connect all kinds of services among them. Like any other piece of software, a Web API is continuously changing, and with each change, all client applications must evolve. This adaptation process is critical and essential for software developers. In this paper, we present an exploratory evaluation of the most common changes occurring during the evolution of REST APIs. We define a taxonomy of structural API changes, which we classify according to their impact on client-side software; and propose a repository mining process to identify these changes in real Web APIs. We apply this process to a large set of Azure APIs from APISGURU, a well-known Open Source API repository. Based on the analyzed dataset from APISGURU, we found that breaking changes tend to decrease when a new version of an API from this dataset is released. Other useful findings and insights are discussed throughout the article.

SAXJS: An Online Change Point Detection for Wearable Sensor Data
Authors: Riqueti Giovanna A. , Barros Pedro H. , Borges João B. , Cunha Felipe D. , Rosso Osvaldo A. , Ramos Heitor S.
Published: June 2023

Wearable electronics are devices used by humans that can continuously and uninterruptedly monitor human activity through sensor data. The data collected by them have several applications, such as recommending running techniques and helping to monitor health status. Segmenting such data into chunks containing only a single human activity is challenging due to the wide variability of underlying process characteristics presented in the data. To deal with this problem, we propose a new change point detection algorithm based on the Symbolic Aggregate approXimation (SAX) transformation, the probability of transition between symbols, and the Jensen-Shannon distance.
Detecção Eficiente de Anomalias em Redes de Data Centers Apoiada por Aprendizado de Máquina e Otimizador do Lobo Cinzento para Seleção de Atributos
Authors: Salvador Henrique G. , Batista Daniel M. , Santos Aldri Luiz Dos , Nogueira Michele
Published: June 2023

A elevada taxa de transmissão em redes de Data Centers exige que tais redes empreguem mecanismos que utilizem poucos atributos do tráfego para detecção de anomalias, evitando assim um alto consumo de recursos para o monitoramento da rede. Além disso, é importante que a detecção possua uma alta precisão, evitando falsos positivos e falsos negativos. Este artigo propõe uma solução com essas características, apoiada no algoritmo KNN para a detecção de anomalias e no otimizador GWO para a seleção dos principais atributos do tráfego. Em experimentos com a solução analisando o dataset UNSW-NB15, foi possível observar uma redução de 86,21% na quantidade de atributos utilizados para detectar anomalias na rede, além de melhoria na acurácia da detecção.

Atualmente, a demanda por comunicação por redes sem fio tem crescido exponencialmente. Contudo, as tecnologias de comunicação sem fio disponíveis hoje podem não ser suficientes para acompanhar a crescente demanda por banda. Nesse contexto, a Comunicação por Luz Visível (VLC) consiste em uma possibilidade válida e promissora, tendo em vista a alta taxa de transferência de dados, a utilização de uma infraestrutura de iluminação já amplamente difundida na atualidade, além de um largo espectro disponível e não reservado para o uso. Logo, este trabalho tem como objetivo apresentar uma implementação do protocolo de rede Multicast na Comunicação Por Luz Visível.
Dispositivos, Eu Escolho Vocês: Seleção de Clientes Adaptativa para Comunicação Eficiente em Aprendizado Federado
Authors: Souza Allan M. de , Bittencourt Luiz F. , Cerqueira Eduardo , Loureiro Antonio A. F. , Villas Leandro A.
Published: June 2023

O aprendizado federado (Federated Learning – FL) é uma abordagem distribuída para o treinamento colaborativo de modelos de aprendizado de máquina. O FL requer um alto nível de comunicação entre os dispositivos e um servidor central, assim gerando diversos desafios, incluindo gargalos de comunicação e escalabilidade na rede. Neste trabalho, introduzimos DEEV, uma solução para diminuir os custos gerais de comunicação e computação para treinar um modelo no ambiente FL. DEEV emprega uma estratégia de seleção de clientes que adapta dinamicamente o número de dispositivos que treinam o modelo e o número de rodadas necessárias para atingir a convergência. Um caso de uso no conjunto de dados de reconhecimento de atividades humanas é realizado para avaliar DEEV e compará-lo com outras abordagens do estado da arte. Avaliações experimentais mostram que DEEV reduz eficientemente a sobrecarga geral de comunicação e computação para treinar um modelo e promover sua convergência. Em particular, o DEEV reduz em até 60% a comunicação e em até 90% a sobrecarga de computação em comparação com as abordagens da literatura, ao mesmo tempo em que fornece boa convergência mesmo em cenários em que os dados são distribuídos de forma não independente e idêntica entre os dispositivos clientes.

Published: June 2023

Connected and autonomous vehicles (CAVs) are part of the Internet of Things, exposing them to cyberattacks. CAVs comprise several systems, such as advanced driver assistance systems, that require high bandwidth for critical data transmission, where automotive Ethernet plays an essential role as an enabling technology. In this paper, we propose a deep learning-based intrusion detection system for detecting replay attacks in an automotive Ethernet network. It uses a convolutional neural network architecture and a multi-criteria optimization technique. Our experimental results show a reduction of 900x in the storage size and a speedup of 1.4x in the detection time with a negligible drop in the F1-score compared to existing work.

Published: June 2023

In a vehicle platoon, the Information Flow Topology consists of the structure and organization of the communication network that interconnects the vehicles. When there is a high Frame Error Rate in the communication network, the vehicle platoon can become unstable and put drivers and passengers at risk. This work investigates the influence of the Information Flow Topology on a platoon in scenarios with different speeds, acceleration and deceleration amplitude, and levels of packet loss. Simulation results demonstrated that the Predecessor Follower topology can maintain safety and a more accurate intervehicular distance even in nonideal vehicular communication scenarios.
Medium Access Control Techniques for Massive Machine-Type Communications in Cellular Networks
Authors: Astudillo Carlos A. , Fonseca Nelson L. S. da
Published: June 2023

A key component of the Internet of things (IoT) ecosystem is wide-area network connectivity, for which cellular network technologies are a promising option through their support of massive machine-type communication (mMTC). However, numerous devices transmitting sporadically small data packets in a highly synchronized way can generate overload on the radio access network, leading to a shortage of resources, especially those associated with the random access procedure, such as orthogonal preambles and control and data resources. This paper summarizes the main contributions of the first author’s doctoral dissertation supervised by the second author. The dissertation proposes medium access control (MAC) techniques for addressing problems related to the support of mMTC in cellular networks. Results show that the proposals support quality of service (QoS), decrease access latency, decrease the device energy consumption, and increase the probability of successful channel access and resource utilization under massive random access.
Enabling Self-Driving Networks with Machine Learning
Authors: Jacobs Arthur Selle , Ferreira Ronaldo Alves , Granville Lisandro Zambenedetti
Published: June 2023

This work aims to enable self-driving networks by addressing the lack of trust that network operators have in Machine Learning (ML) models for networking problems. To achieve this, we propose a natural-language conversational interface (LUMI) and a new ML pipeline that uses techniques from the emerging field of eXplainable Artificial Intelligence (XAI) to scrutinize models. We also propose a new XAI method called TRUSTEE to extract explanations from any given black-box ML model in the form of decision trees of manageable sizes. Our results indicate that ML models used in networking problems need to be put under proper scrutiny and corrected to fulfill their tasks properly.

Published: June 2023

Os progressos em bioengenharia e nanotecnologia têm impulsionado avanços nas nanomáquinas implantáveis. A comunicação entre esses dispositivos é igualmente um requisito e um desafio de pesquisa para avançar o novo paradigma das nanorredes. Esta tese preenche as necessidades desse novo paradigma fornecendo os blocos de construção (codificação, controle de erros e controle de acesso ao meio) para as redes intracorporais. Os blocos de construção tomam a comunicação molecular como base para codificar dados através de moléculas. A hipótese central desta tese reside no poder da diversidade molecular para melhorar o desempenho da comunicação molecular com baixa complexidade. Assim, o trabalho caracteriza os componentes naturais da comunicação molecular e valida a hipótese, considerando um ambiente biológico celular emulado. Os resultados mostram que a diversidade molecular beneficia a comunicação molecular em capacidade, perda de caminho e probabilidade de erro, enfatizando as contribuições provenientes dos blocos de construção.

A experimentação é uma etapa imprescindível para muitos tipos de pesquisas científicas, visto que a partir dela o pesquisador pode observar a validade de suas hipóteses. No contexto de redes de computadores, durante a fase de experimentação, é desafiador encontrar geradores de carga que sejam capazes de modelar padrões de tráfego para os mais diversos tipos de aplicações. Neste sentido, este trabalho apresenta o WAVE - uma carga de trabalho para experimentos verificáveis. Tendo como característica ser agnóstico à aplicação, o WAVE foi amplamente executado em testes de carga para aplicações de vídeo sob demanda e armazenamento de chave-valor. Na versão atual, o WAVE é capaz de gerar cargas para dois padrões distintos: sinusoidal e flashcrowd.

A Open-RAN (O-RAN) torna o mercado móvel mais competitivo através da desagregação das Redes de Acesso via Rádio (RANs). Interfaces padronizadas e Controladores Inteligentes da RAN (RICs) permitem a interoperabilidade entre diferentes fornecedores de hardware e de software. No entanto, a complexidade da arquitetura, das implementações e do desenvolvimento de aplicações para controle e otimização dos RICs atrasam sua implantação. Neste trabalho, apresentamos um módulo para prototipação e desenvolvimento de aplicações para RICs de uma rede O-RAN no simulador de redes ns-3.

The use of virtual and software-based environments, such as Mininet, has become popular for network experimentation. However, these platforms often have limitations, including low transmission speeds and trade-offs between scalability and performance fidelity. Advances in P4 programmability and new P4 hardware that supports Tofino Native Architecture (TNA) have enabled the possibility of emulating various network link characteristics and creating network topologies for running line-rate traffic in a single P4 switch (i.e., Tofino). In this paper, we introduce the P7 (P4 Programmable Patch Panel) emulator, which allows the configuration of network scenarios with different link characteristics, including 100G traffic capacities, using a single P4 switch. We demonstrate the scalability and realism of the P7 emulator, making it an ideal environment for network research and experimentation.

Em acidentes de trânsito extremos, vítimas frequentemente não conseguem entrar em contato com as equipes de resposta a emergência a tempo. Visando automatizar o processo de detecção e relato de acidentes, este artigo apresenta resultados parciais da comparação de diferentes estratégias para resposta a emergências que usam as capacidades de comunicação de Redes Ad Hoc Veiculares (VANETs) assistidas por computação na névoa para relatar emergências com a ajuda de uma unidade de resposta a emergência. Experimentos de simulação mostraram que algumas estratégias podem reduzir o tempo total de resposta a emergências em até 60,13%. O software desenvolvido está disponível como software livre permitindo a reprodução dos experimentos.

Published: June 2023

Software-Defined Networking has been used to leverage security solutions for wireless sensor networks. However, this paradigm turns networks vulnerable to distributed denial of service attacks. IDIT-SDN is a tool for Software-defined Wireless Sensor Networks devised for DoS and DDoS attacks simulation and detection. This tool provides a framework for anomaly detection and a communication protocol to share security wise information from the sensor network to the controller. We demonstrate its use by showing a cooperative DDoS attack detection and attacker identification application based on distributed (every node) and centralized (controller) anomaly detection.

Published: June 2023

This research paper presents a Virtual Machine Placement algorithm designed to optimize the service allocation process, which is one of the most significant challenges in resource allocation and management. Our solution employs a ranking strategy based on global resource scarcity, where we consider all the information contained in datacenter hosts during the allocation process. We compare our approach with two different literature-based methods regarding task allocation time and the number of allocated resources. To evaluate our proposal, we consider scenarios in which requisitions arrive at different times or simultaneously. The first scenario represents a realistic situation where no knowledge is available regarding task arrival. Meanwhile, the second scenario represents a dense situation where many tasks arrive together. Our evaluations show that our solution yields better results in both cases, especially when requisitions arrive simultaneously. Our solution reduced the allocation time by around 25% on average and achieved better load distribution among hosts.

Published: June 2023

Denial-of-Service (DoS) attacks have been extensively studied in the literature, especially in their most dangerous form, the Distributed Denial-of-Service (DDoS). Database, a critical infrastructure for services, has mechanisms for recording information (logs) of SQL queries and sessions. Although they are vulnerable to DDoS, they are not entirely covered by commercial tools or research on such a detection. Machine Learning (ML) techniques are highly effective in identifying patterns in data such as database SQL logs. Thus, this work proposes the application of ML to detect DDoS attacks on a database from the logs of queries executed on it. As a result, the classification obtained an F1-score of 94.44%, which indicates the effectiveness of the proposed approach.

Published: June 2023

Autonomous driving requires machine learning models to be trained at the edge for improved efficiency and reduced communication latency. Federated learning (FL) allows knowledge sharing among all devices, but Not Independent and Identically Distributed (non-IID) scenarios with biased device data distributions can lead to statistical heterogeneity and lower classification accuracy. This paper proposes an entropy-based client selection approach for vehicular federated learning environments that aims to address the challenges posed by non-IID data in vehicular networks. The proposed method is compared to a random selection mechanism in both IID and non-IID scenarios, as well as in a scenario with random client drops. The results show that the entropy-based selection method outperforms the random selection method in all compared metrics, particularly in non-IID scenarios.

Background: Hepatocellular carcinoma (HCC) is a common solid tumor and the third cause of cancer death worldwide. Resistance to chemotherapeutic drugs is a serious challenge in the treatment of HCC. To address this challenge, therefore, attempts have been made to develop novel anticancer agents by using medicinal plants and producing novel natural chemical compounds. Objectives: This study aimed to investigate the anti-proliferative effect of the Satureja sahandica extraction combined with layered double hydroxide (LDH) nanosheets on the HepG2 HCC cell line. Methods: The anti-proliferative effects of S. sahandica extraction and LDH nanosheets on HCC cell line HepG2 were investigated by adopting the MTT method. The morphological alterations, migration, and apoptosis rates were also evaluated in the treated cancer cells. The apoptosis-related genes mRNA expressions (BAX and BCL2) were examined by performing real-time PCR. Results: According to the study results, the S. sahandica extraction treatments significantly decreased the viability and proliferation of the HCC cell line HepG2. However, the anticancer activity of the S. sahandica extraction and LDH nanosheet combination was significantly less than its monotherapy. Various morphological alterations and apoptosis rates increased in the cancer cells. However, the migration rate of the cancer cells significantly decreased. Furthermore, the expressions of BAX and BCL2 genes were upregulated and downregulated, respectively. Conclusions: In sum, the significant anti-proliferative activity of the S. sahandica extraction against the HCC cells was documented, which may have been due to the induction of apoptosis. However, LDH nanosheets decreased the anti-proliferative activity of S. sahandica extraction.
