Texto completoResumen
It is substantiated that steganographic systems should be used to ensure the protection of special information resources in conditions of its prompt delivery. Here, steganographic technologies are an integral part of complex information protection systems. Simultaneously, for steganographic systems, there is a contradiction between the density of embedded data and level of information compaction of video container (level of reduction of volume bit volume of compact presented video image concerning bit volume of an initial video image). It leads to the fact that under the conditions of the required quality (reliability) of digital video information, the bit rate level of the covert channel is insufficient. Consequently, the scientific-applied problem concerns the necessity to increase the integrity (the level of correspondence of the hidden information before its embedding in a video container and after its extraction) and bit rate of the hidden channel of special information transmission. It is relevant. The solution of the described problem in the field of application of steganographic transformations can be realized based on the application of two different approaches. The first approach is based on methods of direct message embedding. But this approach is characterized by introducing distortions in the video images used as a container. Therefore, changes in structural and statistical patterns in the syntactic description of the video container happen. It reduces the potential for video container compaction. The second approach to creating steganographic transformation methods is based on information hiding using indirect embedding technique. Here, the embedding process exploits the functional dependency between the elements of the video container and the elements of the embedded message. Setting a specific dependency between the elements in the video container corresponds to the embedded element with a value of "0" or "1". However, the existing indirect steganographic transformation methods have a disadvantage. It consists of an insufficient value of embedded data density. To eliminate these disadvantages, it is proposed to develop an approach that allows using not only psychovisual but also structural redundancy of video container for concealment. Therefore, the research objective of this paper is to develop a method for indirect information withholding in the video container compression process to increase the bit rate of the hidden message channel. In the process of research, a steganographic multiagent system is constructed, which allows embedding hidden message elements without loss of information based on the indirect approach by modifying the active bases of the multiagent basis considering their uncertainty. To select transformants (data sets) as containers for information embedding, the requirement of the existence of a base system with all active bases is taken into account. The number of embedded bits of the hidden message is equal to the number of active bases in the base system of the multiadic space. Because of the made experiments, the following results have been received: in the process of embedding messages based on the created method distortions in a video container is not brought; for the created method the additional increase in the hidden channel bit rate in average 5 … 7 times are reached.

Run-time profiling of software applications is key to energy efficiency. Even the most optimized hardware combined to an optimally designed software may become inefficient if operated poorly. Moreover, the diversification of modern computing platforms and broadening of their run-time configuration space make the task of optimally operating software ever more complex. With the growing financial and environmental impact of data center operation and cloud-based applications, optimal software operation becomes increasingly more relevant to existing and next-generation workloads. In order to guide software operation towards energy savings, energy and performance data must be gathered to provide a meaningful assessment of the application behavior under different system configurations, which is not appropriately addressed in existing tools. In this work we present Containergy, a new performance evaluation and profiling tool that uses software containers to perform application run-time assessment, providing energy and performance profiling data with negligible overhead (below 2%). It is focused on energy efficiency for next generation workloads. Practical experiments with emerging workloads, such as video transcoding and machine-learning image classification, are presented. The profiling results are analyzed in terms of performance and energy savings under a Quality-of-Service (QoS) perspective. For video transcoding, we verified that wrong choices in the configuration space can lead to an increase above 300% in energy consumption for the same task and operational levels. Considering the image classification case study, the results show that the choice of the machine-learning algorithm and model affect significantly the energy efficiency. Profiling datasets of AlexNet and SqueezeNet, which present similar accuracy, indicate that the latter represents 55.8% in energy saving compared to the former.

Texto completoResumen
It is shown that the current direction of increasing the safety of information resources when transmitting information in info-communication systems is the use of methods of steganographic instruction in video imagery. The effectiveness of such methods is significantly increased when used in a complex of methods of concealment, which are based on the principles of inconsistent and cosmic communication. At the same time, existing methods of steganographic are used in the process of insertion of information mainly only laws, empty features of visual perception of video images. So, it is justified that the scientific and applied problem, which is to increase the density of embedded messages in the video container with a given level of their reliability, is relevant. The solution of this problem is based on the solution of the contradiction, which concerns the fact that increasing the density of embedded data leads to a decrease in the bit rate of the video container, steganalysis stability, reliability of special information, and video container. Therefore, the research aims to develop a methodology for the steganographic embedding of information, taking into account the regularities of the video container, which are generated by its structural and structural-statistical features. The solution to the posed problem of applying steganographic transformations is proposed to be realised by methods of indirectly embedding parts of the hidden message in certain conditions or functional relationships. The possibility of creating steganographic transformations regarding the indirect embedding and extraction of hidden information in a multiadic basis by modifying the underlying basis system within an admissible set is demonstrated. It is shown that the multiadic system, which is created in the spectral space of DCT transforms, has the potential to form a set of admissible modifications of basis systems.

Texto completoResumen
The use of islands and archipelagos as settings in video games has proven enduring and popular: these locations are usually shown to be dangerous places where travel can be difficult. The use of island and archipelago settings in this medium developed along with conventions about water in general being an obstacle to traverse, meaning that player characters that experience islands and archipelagoes are forced to discover ways to travel around, over, and away from them. Islands remain popular settings because they work well with players’ preconceptions about these spaces, with people’s understandings of natural boundaries that make travel difficult, and with game designers’ intent to control player character movement throughout a world that is necessarily constrained by the reach of technology.

The determinants of the strategies to be employed by video streaming sites are application (mobile devices or web browsers) and container of the video application. They affect video streaming network characteristics, which is often the traffic flow, and its quality. It is against this background that studies on streaming strategies suggested the need to investigate and identify the relationship between buffer time, video stream protocol, packet speed and size, upload time, and waiting period, specifically to aid network administrative support in case of network traffic bottlenecks. In view of this, this study investigates the network characteristics of YouTube and Vimeo, using experimental methodology, and involving WireShark as network analyzer. Google Chrome and Firefox are the web browsers employed, while packet size, protocols, packet interval, TCP window size and accumulation ratio are the metrics. Short ON-OFF, Long ON-OFF, and No ON-OFF cycles are the three streaming strategies identified. It is further shown that both Vimeo and YouTube employ these strategies but the choice depends on the container of the video streamed.

Cloud-based video processing is an area depending heavily on the hardware’s ability to process huge amounts of packets. Nowadays, we can observe industry drifting away from commonly used FPGAs in lieu of a more flexible software approach. Docker container has been considered a promising technology for constructing video streaming pipelines as it provides a fast and easy way to package and distribute software. Recent developments in the Network Function Virtualization field showed that fast packet processing frameworks like Intel Data Plane Development Kit (DPDK) have a potential to improve the performance of network function chains. This technology could be an enabler for software video processing to approach hardware solutions, yet it is still in quite an early stage and generates many questions about usage, deployment, and performance. This thesis shows that it is possible to build packet processing pipelines using DPDK, running dozens of video processing microservices simultaneously on a single machine. The project implementation was evaluated in terms of latency and throughput and behaviour of co-running applications on a single CPU core was modelled.Molntjänster Inom området videobearbetning är starkt beroende av hårdvarans förmåga att kontinuerligt bearbeta mycket stora mängder paket. Idag har det blivit vanligt inom professionell användning att välja bort tidigare vanliga FPGA-baserade lösningar, till förmån för mer flexibla mjukvarubaserade lösningar. Docker containers har setts som en lovande teknologi för att konstruera pipelines för strömmande video, då de erbjuder ett snabbt och enkelt sätt att paketera och distribuera mjukvara. Utvecklingen inom virtualisering av nätverksfunktioner (NFV) har visat att ramverk för snabb paketprocessning, såsom Intel DPDK, har potential att förbättra prestandan hos kedjor av nätverksfunktioner. Denna teknologi gör det möjligt för mjukvarubaserad videobehandling att hävda sig i jämförense med hårdvarubaserade varianter. Den är dock relativt ny och oprövad och det kvarstår många öppna frågor om användning, driftsättning och prestanda. Detta examensarbete visar att det är möjligt att bygga paketbearbetande pipelines med DPDK, som kör dussintals nätverksfunktioner samtidigt på en maskin. En implementation har konstruerats och utvärderats med fokus på latens och flöde, och beteendemönster för applikationer som kör samtidigt på samma CPU har modellerats.

Texto completoResumen
One way for students with disabilities to receive instructional support from someone other than the lead classroom teacher is through paraprofessionals. Paraprofessionals who are not trained properly, however, can negatively impact student success rates. One intervention that has been explored has been the use of video modeling to train staff on various instructional and behavior management strategies. The purpose of this study was to evaluate the effectiveness of using video training to teach paraprofessionals how to implement errorless learning strategies with students. The participants within this study were three female paraprofessionals that were of Caucasian, Latino, and Ukranian descent and had worked in a classroom for at least one year. The dependent variables within this study were evaluated by use of a single subject, multiple baseline design across participants. Results of this study revealed that video training with a focus on errorless learning was effective in increasing paraprofessional percent correct implementation of the strategy, as indicated by an increase in exhibition of the strategy throughout observation and generalization sessions. Paraprofessional implementation of errorless learning procedures increased from a mean of 12.5% accuracy during baseline to 84% accuracy during intervention sessions. Generalization probes maintained high accuracy rates as well, with a mean of 88% accuracy across all three participants. The social validity results provided to the participants at the end of the study indicated that all participants prefer video training over in person training.

Sound is an important part of almost all media. In games, sounds are used to evoke intense emotions in players. Studies has showed that music on its own can induce emotions. Soundeffects is another type of sounds that appear in games. However, do they contribute to the emotional experience? Understanding this will help sound designers enhance scenes in future video games. In this study, 23 participants were asked to conduct a test divided into two part. In the first part they were tasked to listen to four sound effects of fire and choose attributes from a predetermined list that they thought suited. Among these physical attributes were two emotional attributes. In the second part, the subjects were tasked with choosing one of the fours sound effects for a scenario with a positive emotion and motivate their choice. The results show that no sound had neither positive nor negative as an emotional attribute. Of the four sounds, two showed significance that emotion alone was an attribute for the sound. The results from the second part showed that the subjects were divided in what motivated them to choose a sound. More than a third of the subjects based their choice only on if the sound matched the emotion of the scenario presented while slightly less than a third based it only on to fit the location. The last third based it on both emotion and location.

Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorThe administration of medication and nutrients via parenteral is very used nowadays. One of the risks of this procedure is the presence of contaminants, which depending on their nature may cause severe damage to the patients due to the direct way of the administration (in the circulatory stream). In this work we investigated the possibility of the containers to be sources of metals for solutions of parenteral nutrition. The investigated containers are made of different kinds of glass and plastic polymers, namely polypropylene, PVC and EVA. The system container/solution (amino acids, salts, glucose and lipids) individually stored, was submitted to the sterilization process and after that stored for a time period of approximately 10 months, since the shelf-life period of these formulations are generally 2 years. After the sterilization and at regular time intervals, aliquots of each solution were collected and their contents on Al, Pb, Cd, Fe, Cr, Mn, Ba, and Zn were measured by graphite furnace atomic absorption spectrometry. The containers were also analyzed for the determination of the amount of each metal they contained. These metals are either constituents of the container material, as Al in glasses, or impurities in the case of plastic polymers. All containers presented the metals investigated. The solutions, depending on their composition (species dissolved) were able to extract the metals either from the glass or the polymers. The highest extraction rates occurred in solutions of the amino acids cysteine and glutamic acid, and in solutions of NaHCO3. The metals released in higher concentration were Ba, Pb and Zn form plastic containers and Al, Pb and Zn form glass containers. A different behavior was observed among the plastic polymers, and the different kinds of glass. While EVA was the most inert polymer, the clear glass ampoule released the highest amount of metals into the solutions. Fifty commercial samples were analyzed as well, and the investigated metals were found in all of them. The commercial formulations presented the same tendency of the individual sample used in the study, either in relation to the behavior of the substance in solution or the container material.
Atualmente a administração parenteral, tanto de medicamentos quanto nutrientes, é uma prática muito difundida. Um dos riscos desta prática é a presença de contaminantes que, dependendo da sua natureza, podem acarretar graves danos aos pacientes devido à forma direta (na corrente circulatória) da administração. Neste trabalho, investigou-se a possibilidade das embalagens serem fontes de contaminação por metais de soluções utilizadas na nutrição parenteral. As embalagens investigadas incluíram vários tipos de vidro e polímeros plásticos mais comumente utilizados (polipropileno, polivinil cloreto (PVC) e etil vinil acetato(EVA)). As embalagens, nas quais foram armazenados individualmente os constituintes das soluções parenterais (aminoácidos, sais, glicose, vitaminas e lipídeos), foram submetidas ao processo de esterilização e de armazenagem a longo prazo, visto que a validade deste tipo de formulação é geralmente de 2 anos. Após a esterilização e em intervalos de tempo regulares, alíquotas das soluções foram retiradas e os teores em Al, Pb, Cd, Fe, Cr, Mn, Ba e Zn foram medidos por espectrometria de absorção atômica forno de grafite (GF AAS) e espectrometria de massa com plasma indutivamente acoplado (ICP-MS). As embalagens utilizadas foram também analisadas para determinar quanto dos metais em estudo elas apresentavam, seja como constituinte, como é o caso do Al no vidro, ou como impureza, no caso de todos os metais nos polímeros plásticos. Todas as embalagens continham os metais em estudo em maior ou menor concentração. As soluções, dependendo dos seus constituintes foram capazes de extrair os metais, tanto do vidro quanto do plástico. As maiores taxas de extração ocorreram com as soluções dos aminoácidos cisteína e acido glutâmico. Os metais extraídos em maiores quantidades foram Ba, Pb e Zn das embalagens plásticas e Al, Pb e Zn das embalagens de vidro. Observou-se diferente comportamento entre os diferentes polímeros e tipos de vidro. O EVA mostrou-se o polímero mais inerte, enquanto que as ampolas transparentes foram as que mais metais liberaram para as soluções. Foram analisadas, também, 50 amostras comerciais, as quais se mostraram contaminadas pelos metais em estudo. Observou-se nas soluções comerciais a mesma tendência das soluções individuais do estudo, tanto com relação ao comportamento da embalagem, quanto ao conteúdo (ação do componente sobre a embalagem) e os metais extraídos.

Texto completoResumen
O problema de dimensionamento e sequenciamento de lotes vem sendo extensivamente estudado por pesquisadores da área de Pesquisa Operacional e há uma tendência de que tais trabalhos passem a cada vez mais integrar aspectos reais dos processos produtivos. Entretanto, percebe-se que os estudos conduzidos em alguns setores industriais negligenciam importantes restrições tecnológicos dos processos de produção e isso afasta esses trabalhos de Pesquisa Operacional de uma aplicação efetiva, como é o caso da indústria de embalagens de vidro. Neste contexto, propõe-se um modelo de programação inteira mista e um método de solução para o problema de dimensionamento e sequenciamentos de lotes na indústria de embalagens de vidro, sendo que este trabalho diferencia-se dos demais existentes na literatura por agregar restrições tecnológicas específicas desse processo produtivo. O modelo proposto, denominado CLSD-GCST, foi amplamente validado com base em um conjunto de testes com 40 instâncias de um problema real de uma grande empresa do setor no pacote comercial IBM ILOG CPLEX Optimization Studio Versão 12.5. A validação do modelo incluiu ainda uma análise de ganhos potenciais para o negócio de baseada no modelo SCOR. Já o método de solução proposto consiste em uma metaheurística de Busca em Vizinhança Variável (VNS) e se mostrou promissor para a solução do problema estudado, proporcionando resultados de qualidade em um baixo tempo computacional. Além disso, o VNS superou o Branch-and-Cut do CPLEX para grandes instâncias, nas quais o pacote comercial encontrou dificuldades. Por fim, o VNS proposto também foi validado por meio da análise de testes computacionais e suas principais características foram avaliadas sistematicamente, gerando um conjunto de informações que pode direcionar a utilização e, até mesmo, a evolução desse método em pesquisas futuras.Lot sizing and scheduling problem has been extensively studied by Operations Research scientists and there is a tendency of incorporating more production processes real aspects in these researches. However, it can be noticed that studies conducted in some industrial sectors neglect important production process technological constraints and it keeps the Operations Research works away from an effective application, as happens with the glass containers industry. In this context, a mixed integer programming model and a solution method were proposed for glass containers industry lot sizing and scheduling problem, the main difference between this work and the others in literature is the inclusion of process specific technological constraints. The proposed model, named CLSD-GCST, was widely validated by a set of tests performed with 40 instances from a large company real problem using the commercial package IBM ILOG CPLEX Optimization Studio Version 12.5. The model validation also included a potential business earnings analysis based on SCOR framework. About the proposed solution method, it consists of a Variable Neighborhood Search (VNS) metaheuristic and it proved to be promising for the studied problem solution, providing good quality results in low computational time. Moreover, VNS overcame the CPLEX Branch-and-Cut for large instances, in which the commercial package found difficulties. Lastly, the proposed VNS was validated by means of computational tests analysis and its main characteristics were systematically evaluated, generating an information set that may direct this method application and even its evolution in future researches.

Mestrado em Gestão e Estratégia IndustrialEm 2019, a Secretaria Geral do Ambiente, Operadora do Programa "Ambiente, Alterações Climáticas e Economia de Baixo Carbono" em Portugal, lançou o concurso "Sistema de reembolso de depósito para garrafas de bebidas e latas", financiando projetos nestas áreas. O objetivo deste trabalho é discutir se os Sistemas de Depósito e Reembolso (SDR) são os instrumentos mais custo-eficientes para fazer a transição de um sistema económico linear, para um sistema circular. Para alcançar este objetivo, esclareceram-se os conceitos de Economia Circular (EC) e de SDR para, depois, os aplicar na análise da circularidade dos projetos. Para o esclarecimento conceptual, fez-se uma revisão da literatura com dois objetivos: enquadrar historicamente o conceito de EC e definir os SDR enquanto instrumentos económicos de mercado simultaneamente custo-eficientes e respeitadores dos princípios da circularidade. Concluiu-se que a literatura aconselha a definição de EC proposta pela fundação Ellen MacArthur e que os SDR são instrumentos custo-eficientes para fechar o ciclo dos fluxos de materiais. Fez-se a análise qualitativa dos projetos de SDR propostos a concurso para avaliar o seu grau de circularidade. Concluiu-se que: aquilo que hoje se designa EC terá as suas raízes nos modelos de fluxos de materiais; que o conceito de EC ainda não está estabilizado; que os SDR são instrumentos de política ambiental mais custo-eficientes para fechar o ciclo de materiais; que, no curto prazo, os indicadores definidos no âmbito do concurso não serão todos cumpridos; e, por último, que nem todos os projetos vão ao encontro dos princípios da Economia Circular.

The escalation of multimedia contents exchange, especially of videos belonging to mobile
devices, and the availability of a great amount of editing software has raised grave
doubts on their digital life-cycle. In this thesis, we firstly introduce a new dataset
for multimedia forensics and then develop forensic tools that analyse the
video-container and the video-signal in order to evaluate possible tampering that have
been introduced in the life-cycle of a video content.
The first contribution consists on the release of a new
Dataset of videos and images captured from to 35 modern smartphones/tablets
belonging to 11 different brands: Apple, Asus, Huawei, Lenovo, LG electronics,
Microsoft, Oneplus, Samsung, Sony, Wiko and Xiaomi.
Overall, we collected 11732 native images; 7565 of them were shared
through Facebook, in both high and low quality, and through WhatsApp, resulting in a
total of 34427 images. Furthermore we acquired 648 native videos,
622 of which were shared through YouTube at the maximum
available resolution, and 644 through WhatsApp, resulting in a total of 1914 videos.
The uniqueness of the VISION dataset was tested on well known forensic tool, i.e.,
the detection of the Sensor Pattern Noise (SPN) left by the acquisition
device for the source identification of
native/social media contents.
The second contribution is based on the analysis of the container structure of videos acquired by means of mobile devices. We argue that the atoms belonging to the container, in terms of order and value, are fragile and that it is more difficult to hide their modifications than the regular metadata. This characteristic can be exploited to perform Source Identification and Integrity Verification of videos taken from devices belonging to well known operating systems and manufactures.
In the third contribution we focus on the video-signal and on its encoding
process. We used codecs that perform a hybrid video coding scheme,
and developed a classification technique able to perform group of picture length estimation
and double compression detection. The proposed technique is one of the fastest
approaches that use videos encoded with B-frames, with both constant bit rate and
variable bit rate.

É no compromisso desses três níveis de aproximação que cabe ao leitor estabelecer os contágios que indicam pistas de leitura, sabendo que — e essa é a função maior do Posfácio — os eixos conceptuais que as orientam se prolongam nas obras que excedem o período temporal aqui analisado.
Presented to the Colégio das Artes da Universidade de Coimbra under the special regime (Article 31, 2-b, of Decree-Law 230/2009 of September 14th), this thesis gathers my work from the last twenty years around a conceptual framework based on two core notions: o ideário do contentor e a performance como espectro. This thesis is divided into four chapters, each one corresponding to a medium: 1. Drawing, 2. Photography, 3. Video, 4. Objects and Installation. These chapters are preceded by a Preamble which simultaneously introduces the artworks and the key concepts to understand them: action, indeterminacy, appropriation, self-reflexivity, delegation, duration, event score, failure, conceptual script, language, performance, repetition and tautology. The aim is to confront the artworks — presented in chronological order in order to assure a non-hierarchical neutrality — within the creative frame that inscribes each one, and furthermore to reveal the creative process(es) linking the different media, there residing its operative and conceptual basis. Built on a rhizomatic structure of authors and concepts, displayed at the border of the pages, this document expands the possibilities of comprehension of the artworks not only individually, but in the context of their medium and in the general context of the work. Negotiating between these three levels of understanding, the reader must establish the links that function as reading cues, while being aware that the conceptual axis which guide them go beyond the time span of this study.

The RUBI Autism Network has developed and tested a structured parent training manual for children with autism spectrum disorder and disruptive behaviors. The manual is based on principles of applied behavior analysis and is designed for therapists to use with parents of children with autism spectrum disorder and co-occurring challenging behaviors, such as tantrums, noncompliance, difficulties with transitions, and aggression. A trained therapist utilizes the manual to guide the parent in applying techniques and tools to help manage the child’s challenging behaviors. The treatment includes 11 Core sessions, 7 Supplemental sessions, a home visit, and follow-up telephone booster sessions. Each of the sessions contains a therapist script, activity sheets, a parent handout, and treatment fidelity checklists. Additionally, accompanying each core session are video vignettes that the therapist uses to demonstrate concepts taught in the session. The videos include 30- to 60-second vignettes demonstrating common parenting mistakes as well as implementation (to varying degrees of success) of the strategies being taught. The treatment manual is designed to be delivered individually to parents in weekly outpatient visits. Parents are given homework assignments between sessions that focus on applying techniques to specific behaviors.

AbstractIn the previous chapters, multimedia forensics techniques based on the analysis of the data stream, i.e., the audio-visual signal, aimed at detecting artifacts and inconsistencies in the (statistics of the) content were presented. Recent research highlighted that useful forensic traces are also left in the file structure, thus offering the opportunity to understand a file’s life-cycle without looking at the content itself. This chapter is then devoted to the description of the main forensic methods for the analysis of image and video file formats.

Texto completoResumen
AbstractAI-synthesized face-swapping videos, commonly known as DeepFakes, is an emerging problem threatening the trustworthiness of online information. The need to develop and evaluate DeepFake detection algorithms calls for large-scale datasets. However, current DeepFake datasets suffer from low visual quality and do not resemble DeepFake videos circulated on the Internet. We present a new large-scale challenging DeepFake video dataset, Celeb-DF, which contains 5, 639 high-quality DeepFake videos of celebrities generated using an improved synthesis process. We conduct a comprehensive evaluation of DeepFake detection methods and datasets to demonstrate the escalated level of challenges posed by Celeb-DF. Then we introduce Landmark Breaker, the first dedicated method to disrupt facial landmark extraction, and apply it to the obstruction of the generation of DeepFake videos. The experiments are conducted on three state-of-the-art facial landmark extractors using our Celeb-DF dataset.

AbstractThis paper showcases the work that aims at building a user-friendly mobile application of a reverse dictionary to translate sign languages to spoken languages. The concept behind the reverse dictionary is the ability to perform a video-based search by demonstrating a handshape in front of a mobile phone’s camera. The user would be able to use this feature in two ways. Firstly, the user would be able to search for a word by showing a handshape for the application to provide a list of signs that contain that handshape. Secondly, the user could fingerspell the word letter by letter in front of the camera for the application to return the sign that corresponds to that word. The user can then look through the suggested videos and see their written translations. To offer other functionalities, the application also has Search by Category and Search by Word options. Currently, the reverse dictionary supports translations from Russian Sign Language (RSL) to Russian language.

AbstractTraditionally, volleyball coaches’ education has been conducted physically in the gym and classroom, but due to Covid-19 and the actions needed to contain the pandemic, that was no longer possible in the spring of 2020. Instead of canceling the already planned course we decided to move the course online. The development process was guided by the question if we can teach volleyball-specific skills online. As a result, we designed a fully online blended learning course with a problem-centered approach and authentic video-based tasks. A total of 23 prospective coaches took part in the course. Skills acquisition was measured using a pretest-posttest design revealing a large effect of our design on skills acquisition. Additionally, we surveyed participants attitudes towards the learning design. The results show that prospective coaches were satisfied with the design and perceived the online learning course as useful for volleyball coaches’ education. Based on the results, we can recommend the combination of videos and interactive content to provide authentic problem-centered tasks to facilitate skills online in volleyball coaches’ education.

Texto completoResumen
AbstractThe dimensions of the triple bottom-line approach to sustainable development contain inherent conflicting goals in implementation. In cases of urban development around the world, this is exemplary for settings in major port cities. Here, mostly economically oriented infrastructure requirements of the ports meet more comprehensive concerns of sustainable urban development. There are incoherent governance systems: Ports are often involved in higher-level national planning hierarchies, while urban development is predominantly locally controlled. This is also the case in Jakarta Megapolitan with Tanjung Priok Port, Indonesia, the most prominent and still expanding national seaport. The port expansion is also aimed to be a significant hub in one of the world’s maritime axes, which refers to vast urban growth. However, the entire urban economic effects are uncertain, for example, concerning urban diseconomies of scale or rebound effects, such as traffic congestion, social segregation, conflicts, or the digital divide. Urbanization and the contemporary patterns of economic growth are drivers of environmental vulnerability of both parties. This study serves to overcome fragmented approaches by using a holistic, sustainable governance transition process for integrating urban and port-industry governance concepts. A novel online platform, VIDEL (Virtual Dashboard of Environmentally Logistics-Port-City), is designed as a smart system that engages all stakeholders. This platform binds the requirements and interests as well as harmonizing actors in the interactions of urban with port and industry to secure innovative and environmental-friendly way. It will become a digital control tower for sustainable governance system in a port-city.

Texto completoResumen
The chapter describes investigations of steganographic methods of information protection, which use containers represented by files in AVI format. MP3 audio files are selected as data that is embedded in the used container. For the introduction of audio data, the video container was divided into control and information parts. Secret data were embedded in the information part of the video file, which did not lead to distortions when the container file is played. Studies have been conducted to find repetitive blocks in the structure of a video container. The chapter analyzed the determination of the amount of embedded data for containers with different parameters: color saturation, video file resolution, video file length, compression quality, and frames per second. An algorithm has been developed for the introduction and extraction of information represented by sound formats.

Texto completoResumen
Indexing video data is essential for providing content based access. In this paper, we consider how database technology can offer an integrated framework for modeling and querying video data. As many concerns in video (e.g., modeling and querying) are also found in databases, databases provide an interesting angle to attack many of the problems. From a video applications perspective, database systems provide a nice basis for future video systems. More generally, database research will provide solutions to many video issues even if these are partial or fragmented. From a database perspective, video applications provide beautiful challenges. Next generation database systems will need to provide support for multimedia data (e.g., image, video, audio). These data types require new techniques for their management (i.e., storing, modeling, querying, etc.). Hence new solutions are significant. This paper develops a data model and a rule-based query language for video content based indexing and retrieval. The data model is designed around the object and constraint paradigms. A video sequence is split into a set of fragments. Each fragment can be analyzed to extract the information (symbolic descriptions) of interest that can be put into a database. This database can then be searched to find information of interest. Two types of information are considered: (1) the entities (objects) of interest in the domain of a video sequence, (2) video frames which contain these entities. To represent these information, our data model allows facts as well as objects and constraints. We present a declarative, rule-based, constraint query language that can be used to infer relationships about information represented in the model. The language has a clear declarative and operational semantics. This work is a major revision and a consolidation of [12, 13].

Rigotti, Christophe y Mohand-Saïd Hacid. Representing and Reasoning on Conceptual Queries Over Image Databases. Aachen University of Technology, 1999. http://dx.doi.org/10.25368/2022.89.
Texto completoResumen
The problem of content management of multimedia data types (e.g., image, video, graphics) is becoming increasingly important with the development of advanced multimedia applications. Traditional database management systems are inadequate for the handling of such data types. They require new techniques for query formulation, retrieval, evaluation, and navigation. In this paper we develop a knowledge-based framework for modeling and retrieving image data by content. To represent the various aspects of an image object's characteristics, we propose a model which consists of three layers: (1) Feature and Content Layer, intended to contain image visual features such as contours, shapes,etc.; (2) Object Layer, which provides the (conceptual) content dimension of images; and (3) Schema Layer, which contains the structured abstractions of images, i.e., a general schema about the classes of objects represented in the object layer. We propose two abstract languages on the basis of description logics: one for describing knowledge of the object and schema layers, and the other, more expressive, for making queries. Queries can refer to the form dimension (i.e., information of the Feature and Content Layer) or to the content dimension (i.e., information of the Object Layer). These languages employ a variable free notation, and they are well suited for the design, verification and complexity analysis of algorithms. As the amount of information contained in the previous layers may be huge and operations performed at the Feature and Content Layer are time-consuming, resorting to the use of materialized views to process and optimize queries may be extremely useful. For that, we propose a formal framework for testing containment of a query in a view expressed in our query language. The algorithm we propose is sound and complete and relatively efficient.

To represent the various aspects of an image object's characteristics, we propose a model which consists of three layers: (1) Feature and Content Layer, intended to contain image visual features such as contours, shapes,etc.; (2) Object Layer, which provides the (conceptual) content dimension of images; and (3) Schema Layer, which contains the structured abstractions of images, i.e., a general schema about the classes of objects represented in the object layer. We propose two abstract languages on the basis of description logics: one for describing knowledge of the object and schema layers, and the other, more expressive, for making queries. Queries can refer to the form dimension (i.e., information of the Feature and Content Layer) or to the content dimension (i.e., information of the Object Layer). These languages employ a variable free notation, and they are well suited for the design, verification and complexity analysis of algorithms. As the amount of information contained in the previous layers may be huge and operations performed at the Feature and Content Layer are time-consuming, resorting to the use of materialized views to process and optimize queries may be extremely useful. For that, we propose a formal framework for testing containment of a query in a view expressed in our query language. The algorithm we propose is sound and complete and relatively efficient.

This short pedagogical movie illustrates an effect in nuclear physics called backbending which was first observed in the study of the rotational behavior of rapidly rotating rare-earth nuclei in Stockholm, Sweden in 1971. The video contains a mechanical analog utilizing rare-earth magnets and rotating gyroscopes on a turntable along with some historic spectra and papers associated with this landmark discovery together with its explanation in terms of the Coriolis induced uncoupling and rotational alignment of a specific pair of particles occupying high-j intruder orbitals. Thus backbending represents a crossing in energy of the groundstate, or vacuum, rotational band by another band which has two unpaired high-j nucleons (two quasi-particles) with their individual angular momenta aligned with the rotation axis of the rapidly rotating nucleus. Backbending was a major surprise which pushed the field of nuclear structure physics forward but which is now sufficiently well understood that it can be used as a precision spectroscopic tool providing useful insight for example, into nuclear pairing correlations and changes in the latter due to blocking effects and quasi-particle seniority, nuclear deformation, the excited configurations of particular rotational structures and the placement of proton and neutron intruder orbitals at the Fermi surface.

The project exploits the use of Artificial Neural Networks (ANN) to describe infiltration, water, and solute distribution in the soil during irrigation. It provides a method of simulating water and solute movement in the subsurface which, in principle, is different and has some advantages over the more common approach of numerical modeling of flow and transport equations. The five objectives were (i) Numerically develop a database for the prediction of water and solute distribution for irrigation; (ii) Develop predictive models using ANN; (iii) Develop an experimental (laboratory) database of water distribution with time; within a transparent flow cell by high resolution CCD video camera; (iv) Conduct field studies to provide basic data for developing and testing the ANN; and (v) Investigate the inclusion of water quality [salinity and organic matter (OM)] in an ANN model used for predicting infiltration and subsurface water distribution. A major accomplishment was the successful use of Moment Analysis (MA) to characterize “plumes of water” applied by various types of irrigation (including drip and gravity sources). The general idea is to describe the subsurface water patterns statistically in terms of only a few (often 3) parameters which can then be predicted by the ANN. It was shown that ellipses (in two dimensions) or ellipsoids (in three dimensions) can be depicted about the center of the plume. Any fraction of water added can be related to a ‘‘probability’’ curve relating the size of the ellipse (or ellipsoid) that contains that amount of water. The initial test of an ANN to predict the moments (and hence the water plume) was with numerically generated data for infiltration from surface and subsurface drip line and point sources in three contrasting soils. The underlying dataset consisted of 1,684,500 vectors (5 soils×5 discharge rates×3 initial conditions×1,123 nodes×20 print times) where each vector had eleven elements consisting of initial water content, hydraulic properties of the soil, flow rate, time and space coordinates. The output is an estimate of subsurface water distribution for essentially any soil property, initial condition or flow rate from a drip source. Following the formal development of the ANN, we have prepared a “user-friendly” version in a spreadsheet environment (in “Excel”). The input data are selected from appropriate values and the output is instantaneous resulting in a picture of the resulting water plume. The MA has also proven valuable, on its own merit, in the description of the flow in soil under laboratory conditions for both wettable and repellant soils. This includes non-Darcian flow examples and redistribution and well as infiltration. Field experiments were conducted in different agricultural fields and various water qualities in Israel. The obtained results will be the basis for the further ANN models development. Regions of high repellence were identified primarily under the canopy of various orchard crops, including citrus and persimmons. Also, increasing OM in the applied water lead to greater repellency. Major scientific implications are that the ANN offers an alternative to conventional flow and transport modeling and that MA is a powerful technique for describing the subsurface water distributions for normal (wettable) and repellant soil. Implications of the field measurements point to the special role of OM in affecting wettability, both from the irrigation water and from soil accumulation below canopies. Implications for agriculture are that a modified approach for drip system design should be adopted for open area crops and orchards, and taking into account the OM components both in the soil and in the applied waters.
