Object Mapping

Innovative lighting and dynamic sound systems as well as adaptive object mapping solutions constitute a rapidly developing branch of lighting technology and multimedia technology. In order to make it possible to adjust the content to specific objects in the scene, it is necessary to correctly identify them and place them in the accepted frame of reference. Dynamic identification and tracking of objects can be carried out based on two particular types of input data: data from markers installed on objects and data from digital recording systems, founding the operation on infrared (IR), visible light (RGB) and the most advanced RGB-D (RGB and depth) analysis. Most systems used today are those that use various types of markers. This paper presents the advantages and disadvantages of such solutions as well as a target system for dynamic identification and mapping of objects and the human body based on the analysis of data from digital RGB-D cameras. Analyses of identification times, implementation of perspective transformations and 3D-to-2D transformations have been carried out in relation to a planar and cuboidal moving surface. Time analyses have been performed in relation to the resolution of registered and processed images.

Abstract Background: The assessment of spontaneous activity of infants is of fundamental importance to the diagnosis and prediction of abnormal psychomotor development in children. Comprehensive and early diagnosis allows for quick and effective treatment and therapy. Subjective methods are based on the knowledge and experience of the diagnostician. The lack of objective methods to assess the motor development of infants makes it necessary to search for solutions for reliable, credible, and reproducible assessment expressed in numerical or pictorial terms. This study discusses the possibilities of pictorial standardization and optimization of measurable infant behavior based on video recordings. Methods: The authors attempt to perform computer analysis of spontaneous movements depending on the left, right, and front head position. The study was based on data of 26 healthy infants aged 7 to 15 weeks, with three infants included in an in-depth analysis. The selected films represented the input data for the parameters used as the author's temporal and spatial characteristics describing the global movements of the upper and lower limbs. The obtained videos were used as the input data for the algorithm of automatic detection of characteristic points using the OpenPose library. Results: The following movement characteristics were analysed: Factor of Movement's Area (FMA) ("amount of movement in the movement"), Factor of Movement's Shape (FMS) ("circularity” or "ellipticity" of the movement), Center of Movement's Area (CMA) ("inward and outward" and "up and down" movements). Preliminary analysis of the videos showed that the activity of the limbs, especially the upper limbs, may depend on the position of the head.Conclusions: The movement behavior of the infants varies in terms of the range and quality of movement, depending on age and head position.

PurposeCopyright exceptions promote access to information by users without breaching copyright. This research paper reviews copyright exceptions in Kenya, Ghana and Uganda and how they influence access to information in libraries. Objectives were to find out the implications of copyright exceptions in Kenya, Ghana and Uganda; advantages and disadvantages of copyright exceptions for libraries; and recommend best practices of copyright exceptions.Design/methodology/approachThis is a desktop research reviewing empirical literature and incorporating authors' experiential knowledge in their information profession. Authors have interrogated copyright exceptions in their home countries' copyright acts, policy documents and peer-reviewed articles on copyright and information access. They analysed the documents as stated to deduce key recommendations regarding ideal copyright exceptions.FindingsThe study established that copyright exceptions do not always improve access as intended because they are inadequate, ignoring key library functions. Major inconsistencies exist in the exceptions in these countries; key terminologies have not been defined; and the concept is not well understood. Librarians lack sufficient knowledge on exceptions, hence lack self-efficacy in educating users. Kenya, Ghana and Uganda should improve and harmonize their copyright acts to cover key library functions.Originality/valueThis study provides in-depth analysis of historical and modern practices of copyright exceptions in the three countries revealing useful comparative insights. Previous studies looked at the issues from individual countries perspective.

AbstractIn the age of the Internet of Things and social media platforms, huge amounts of digital data are generated by and collected from many sources, including sensors, mobile devices, wearable trackers and security cameras. This data, commonly referred to as Big Data, is challenging current storage, processing, and analysis capabilities. New models, languages, systems and algorithms continue to be developed to effectively collect, store, analyze and learn from Big Data. Most of the recent surveys provide a global analysis of the tools that are used in the main phases of Big Data management (generation, acquisition, storage, querying and visualization of data). Differently, this work analyzes and reviews parallel and distributed paradigms, languages and systems used today to analyze and learn from Big Data on scalable computers. In particular, we provide an in-depth analysis of the properties of the main parallel programming paradigms (MapReduce, workflow, BSP, message passing, and SQL-like) and, through programming examples, we describe the most used systems for Big Data analysis (e.g., Hadoop, Spark, and Storm). Furthermore, we discuss and compare the different systems by highlighting the main features of each of them, their diffusion (community of developers and users) and the main advantages and disadvantages of using them to implement Big Data analysis applications. The final goal of this work is to help designers and developers in identifying and selecting the best/appropriate programming solution based on their skills, hardware availability, application domains and purposes, and also considering the support provided by the developer community.

Tuna fisheries have been identified as one of the major threats to populations of other marine vertebrates, including sea turtles, sharks, seabirds and marine mammals. The development of technical mitigation measures (MM) in fisheries is part of the code of conduct for responsible fisheries. An in-depth analysis of the available literature regarding bycatch mitigation in tuna fisheries with special reference to elasmobranchs was undertaken. Studies highlighting promising MMs were reviewed for four tuna fisheries (longline, purse seine, driftnets and gillnet, and rod and line – including recreational fisheries). The advantages and disadvantages of different MMs are discussed and assessed based on current scientific knowledge. Current management measures for sharks and rays in tuna Regional Fishery Management Organizations (t-RFMOs) are presented. A review of relevant studies examining at-vessel and postrelease mortality of elasmobranch bycatch is provided. This review aims to help fisheries managers identify pragmatic solutions to reduce mortality on pelagic elasmobranchs (and other higher vertebrates) whilst minimizing impacts on catches of target tuna species. Recent research efforts have identified several effective MMs that, if endorsed by t-RFMOs, could reduce elasmobranchs mortality rate in international tropical purse seine tuna fisheries. In the case of longline fisheries, the number of operational effective MMs is very limited. Fisheries deploying driftnets in pelagic ecosystems are suspected to have a high elasmobranchs bycatch and their discard survival is uncertain, but no effective MMs have been field validated for these fisheries. The precautionary bans of such gear by the EU and by some t-RFMOs seem therefore appropriate. Recreational tuna fisheries should be accompanied by science-based support to reduce potential negative impacts on shark populations. Priorities for research and management are identified and discussed.

Purpose – The purpose of this paper is to focus, first, on the analysis of recent trends of the European and Italian food industries, and, second, on the possible implications that the Transatlantic Trade and Investment Partnership (TTIP) negotiate can exert on the Italian agri-food system. Design/methodology/approach – The study is based on an in-depth analysis of current economic trends, characteristics of production structure, and the trade balance of Italy-USA commercial relationship in the context of EU market. The main advantages and disadvantages that can be derived from the TTIP negotiation are pointed out. Findings – The analysis of the Italian food industry highlights a very fragmented production structure characterized by the coexistence on the market of a small number of big companies and a large number of micro, small and medium-sized enterprises. Such bipolar structure constitutes a constraint to internationalization and limits the quantities of exportable products. The TTIP can represent an opportunity for the Italian food small businesses. On the other hand, the main disadvantages are related to the agricultural raw materials market. Originality/value – The study offers an in-depth analysis of the main features of the Italian food industry and of its role in international agri-food trades, describing the scenario that could be opened by the TTIP negotiation.

Sem a água o corpo humano não sobrevive. Não apenas a espécie humana, mas todos os seres vivos necessitam de água para o funcionamento do seu organismo, seja ele animal ou vegetal. À vista disso, e considerando a problemática atual da escassez de água no país e o recente reconhecimento pela ONU do direito à água potável como um direito humano, fica evidente a urgência na busca por meios de preservação deste elemento indispensável para a manutenção da vida. A tributação com finalidade extrafiscal do fornecimento de água potável é uma dentre as opções de ações governamentais que poderia ser utilizada com objetivo de salvaguardar bem tão precioso. Entretanto, indispensável uma análise mais aprofundada sobre as espécies de tributos possíveis para cumprir esta função, principalmente no que tange às suas vantagens e desvantagens, razão pela qual o presente estudo se demonstra necessário.Palavras-chave: Água. Tributação. Extrafiscalidade. Direitos fundamentais. Sustentabilidade.Abstract: Without water the human body does not survive. It is not just the human species, but all living things need water, animal or vegetable. Having that in mind, and considering the current problem of water scarcity in the country and the recent recognition by the UN of the human right to water and sanitation, it is evident the urgency in the search for ways to preserve this element that is indispensable for maintaining life. The extra-fiscal taxation of the supply of drinking water is one of the many options for governmental actions that could be used with the purpose of safeguarding so precious good. However, a more in-depth analysis of the possible tributary types to fulfill this function is essential, especially as regards their advantages and disadvantages. Keywords: Water. Taxation.
