81. Visualização sintético-imagética de parâmetros e metadados de objetos de aprendizagem - Raquel Salcedo Gomes; Daniel Steinbruch Pereira; Érico Marcelo Hoff do Amaral; Rodrigo Sychocki da Silva; Rosana Wagner; Thaísa Jacintho Müller
O presente trabalho traz os resultados de pesquisa que objetivou o desenvolvimento de uma linguagem visual que representasse parâmetros e metadados de objetos de aprendizagem de maneira sintético-imagética, a fim de facilitar seu processo de avaliação e seleção por educadores. A pesquisa fundamentou-se em princípios da teoria de NURBS e da lógica do banco de dados de Manovich (2001, 2010), além dos conceitos de objeto de aprendizagem, metadados e sistemas de recomendação (WILEY, 2000; CAZELLA et al., 2009, 2010). A pesquisa revelou profícua a possibilidade da transformação da cultura subjetiva em dados, mediante a proposição de categorizações que levaram em...

82. DESIGN AND IMPLEMENTATION OF POTENTIOMETER-BASED NONLINEAR TRANSDUCER EMULATOR - Sheroz Khan

This work attempts to design and implement in hardware a transducer with a nonlinear response using potentiometer. Potentiometer is regarded as a linear transducer, while a the response of a nonlinear transducer can be treated as a concatenation of linear segments made out of the response curve of an actual nonlinear transducer at the points of inflections being exhibited by the nonlinear curve. Each straight line segment is characterized by its slope and a constant, called the y-intercept, which is ultimately realized by a corresponding electronic circuit. The complete...

83. Maximizing Strength of Digital Watermarks Using Fuzzy Logic - Sameh Oueslati; Adnane Cherif; Bassel Solaiman
In this paper, we propose a novel digital watermarking scheme in DCT domain based fuzzy inference system and the human visual system to adapt the embedding strength of different blocks. Firstly, the original image is divided into some 8×8 blocks, and then fuzzy inference system according to different textural features and luminance of each block decide adaptively different embedding strengths. The watermark detection adopts correlation technology. Experimental results show that the proposed scheme has good imperceptibility and high robustness to common image processing operators.

84. High-Speed Prefix-Preserving IP Address Anonymization for Passive Measurement Systems - Ramaswamy Ramaswamy , Tilman Wolf
Passive network measurement and packet header trace collection are vital tools for network operation and research. To protect a user’s privacy, it is necessary to anonymize header fields, particularly IP addresses. To preserve the correlation between IP addresses, prefix-preserving anonymization has been proposed. The limitations of this approach for a highperformance measurement system are the need for complex cryptographic computations and potentially large amounts of memory. We propose a new prefix-preserving anonymization algorithm, top-hash subtree-replicated anonymization (TSA), that features three novel improvements: precomputation, replicated subtrees, and top hashing. TSA makes anonymization practical to be implemented on network processors or dedicated...

86. La biometría en las tecnologías de poder de Michel Foucault - Torrano, Andrea
La biometría es una de las tecnologías de control sobre la población más desarrollada y utilizada en la actualidad. En este artículo se analiza la biometría como una tecnología de la lógica securitaria propia de nuestra época. A su vez, se indaga sobre la reactualización de los mecanismos del poder soberano y disciplinario, en tanto tecnología basada en la lógica de inclusión exclusión como también de un ejercicio de poder sobre el cuerpo individual. Además, nos ocuparemos de la incidencia de la biometría sobre la identidad individual.

87. Entre el antagonismo y la institución… los discursos democráticos - Muñoz, María Antonia
El artículo versa sobre la "necesidad" de integrar al análisis de las potencialidades democráticas la historicidad de los discursos y las lógicas de argumentación como condición para la formación de los antagonismos. Para ello se discute la diferencia estructural que existe entre dislocación y antagonismos. Mientras el primero supone una reflexión filosófica ontológica, el segundo remite a la tramitación discursiva de la experiencia de la precariedad de las relaciones sociales. Para abordar estos últimos se requiere de análisis históricos concretos que remiten a los contenidos específicos de los discursos, así como de las lógicas sobre las cuales operan. Finalmente, se...

88. El borde urbano: un acercamiento paisajístico y funcional de los límites del suelo urbanizado en las ciudades medias españolas - Zúñiga Sagredo, Irene
Asistimos a una evolución en la relación entre ciudad y resto del territorio. Este cambio desemboca en la eliminación del límite. La ciudad moderna se diluye en el territorio: el límite tradicional que separaba espacio urbano de espacio natural se ha diluído. La Discontinuidad entre la ciudad y el campo no se produce de forma definida (bien mediante un límite abrupto o con un gradiente) sino mediante una interfase fragmentada de funcionamiento inadecuado y que, además, no permite una clara identificación paisajística, creando problemas de eficiencia y de identidad urbana. El primer objetivo de esta investigación será determinar si existe...

89. Edmund Husserl: phantasía e imaginación. Estudio sistemático del rol y la evolución de las presentificaciones intuitivas en el tránsito hacia la fenomenología transcendental (1898-1913) - Mendoza Canales, Ricardo
La presente tesis doctoral tiene como objetivo llevar a cabo un estudio exhaustivo del rol de la phantasía en el tránsito de la fenomenología como psicología descriptiva en las Investigaciones lógicas hasta su formulación como filosofía trascendental en Ideas I. A lo largo de esta investigación, defiendo la idea de que el tránsito de una fenomenología de corte inmanentista, como la practicada en las Investigaciones lógicas, hacia una fenomenología trascendental cabe ser leída como la búsqueda de un suelo absolutamente evidente que dé cuenta de una distinción definitiva entre percepción y phantasía. Y si en un primer momento la primacía...

90. International Dictatorship or International Democracy. A Discussion of Albert Camus’ 1946 Considerations - Visone Tommaso
In the series Neither Victims Nor Executioners (1946) the Franco-Algerian writer Albert Camus argued for the need of a relative utopia that would allow man, who refused the logic of murder and violence, to revolt against their historical condition. To this end Camus stressed the importance of fighting for a new democratic world order that would have reversed the condition of international dictatorship immanent in the interdependent world of the 20th century. In the series of essays another reading is possible; an attempt to find a new political way after the end of the classic modern world - a system...

91. Implementation of Logic Flow in Planning and Production Control - Ulewicz Robert; Jelonek Dorota; Mazur Magdalena
The article presents the results of analysis, the use of continuous flow of logic at the stage of production planning and control of the company producing furniture. The concept of continuous flow tends to regulate the flow of materials in a manner that provides the shortest flow path without unnecessary activities (Muda is a Japanese word meaning waste), a constant takt and defined throughput at constant resource requirements for the so-called transfer of material through the whole process. In the study Glenday’d sieve method was used to identify the correct area, which requires the value stream mapping, and areas called...

92. Propositional Linear Temporal Logic with Initial Validity Semantics1 - Giero Mariusz
In the article [10] a formal system for Propositional Linear Temporal Logic (in short LTLB) with normal semantics is introduced. The language of this logic consists of “until” operator in a very strict version. The very strict “until” operator enables to express all other temporal operators.

93. Using Scenarios to Assess Policy Mixes for Resource Efficiency and Eco-Innovation in Different Fiscal Policy Frameworks - Laurent Bontoux; Daniel Bengtsson
There is no longer any doubt that the European Union needs to manage a transition towards a sustainable economy and society. The complexity of such an enterprise is creating major challenges that require a future oriented systemic approach, looking at the EU economy and society as a whole, and going beyond current agendas and policies. The purpose of the JRC foresight study “2035: Paths towards a sustainable EU economy” was to explore how this could be possible. Resource efficiency was at the core of the reflection. This created a context where the fiscal framework was perceived by the experts involved...

94. Robust Longitudinal Speed Control of Hybrid Electric Vehicles with a Two-Degree-of-Freedom Fuzzy Logic Controller - Jau-Woei Perng; Yi-Horng Lai
This paper proposes a new robust two-degree-of-freedom (DoF) design method for controlling the nonlinear longitudinal speed problem of hybrid electric vehicles (HEVs). First, the uncertain parameters of the HEV model are described by fuzzy α-cut representation, in which the interval uncertainty and the possibility can be simultaneously indicated by the fuzzy membership function. For the fuzzy parametric uncertain system, the maximum uncertainty interval can be translated into the weighting matrix Q of the linear quadratic tracking problem to guarantee that the designed feedback controller is robust. Second, the fuzzy forward compensator is incorporated with a robust feedback controller to enhance...

95. Criança e apreensão do sentido: experiência midiática televisiva como construção de identidades - Carolina Fernandes da Silva Mandaji

RESUMO

O presente trabalho se propõe a refletir sobre a mídia televisiva e sua relação com o público infantil a partir da apreensão do sentido e construção de identidades. Pensar a lógica da concorrência televisiva que envolve as emissoras predispõe entendê-la, primeiramente, como atividade constitutiva da sociedade contemporânea e, depois, como espaço de visões de mundo e de ideias. Levantamos a hipótese de que a criança como telespectadora está, por um lado, adquirindo uma competência dita televisiva, numa formação que lhe tornará audiência  e, por outro lado, também está construindo visões de mundo. A pesquisa bibliográfica tem como principais autores...

96. A cultura do encontro como resposta à globalização da indiferença - Valdecir Bressani

RESUMO

O Dia Mundial das Comunicações Sociais, a ser celebrado em 2014 pela Igreja Católica tem como tema  “Comunicação a serviço de uma autêntica cultura do encontro”. Uma “cultura do encontro” vem sendo defendida pelo Papa Francisco como contraposto à “cultura da exclusão”, do “descartável”, e da “globalização da indiferença”. Na formação da cultura contemporânea, qual o papel da comunicação? E, a partir do exemplo do papa, quais são as dinâmicas e as lógicas comunicacionais que colaboram com a construção dessa cultura? Com base em autores como Raymond Williams, Pierre Lévy, Canclini, como pensar um novo modelo comunicacional que permita...

99. Developing and Optimising the Use of Logic Models in Systematic Reviews: Exploring Practice and Good Practice in the Use of Programme Theory in Reviews. - Kneale, D; Thomas, J; Harris, K
BACKGROUND: Logic models are becoming an increasingly common feature of systematic reviews, as is the use of programme theory more generally in systematic reviewing. Logic models offer a framework to help reviewers to 'think' conceptually at various points during the review, and can be a useful tool in defining study inclusion and exclusion criteria, guiding the search strategy, identifying relevant outcomes, identifying mediating and moderating factors, and communicating review findings. METHODS AND FINDINGS: In this paper we critique the use of logic models in systematic reviews and protocols drawn from two databases representing reviews of health interventions and international development...

100. Generating Diverse Spinal Motor Neuron Subtypes from Human Pluripotent Stem Cells. - Patani, R
Resolving the mechanisms underlying human neuronal diversification remains a major challenge in developmental and applied neurobiology. Motor neurons (MNs) represent a diverse pool of neuronal subtypes exhibiting differential vulnerability in different human neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and spinal muscular atrophy (SMA). The ability to predictably manipulate MN subtype lineage restriction from human pluripotent stem cells (PSCs) will form the essential basis to establishing accurate, clinically relevant in vitro disease models. I first overview motor neuron developmental biology to provide some context for reviewing recent studies interrogating pathways that influence the generation of MN diversity. I conclude that...
