Questions of Liability Regarding the Malfunctioning of GNSS
No full textThe concept of what developments around the new area of Global Satellite Navigation System law constitute, is playing a growing role within all raising issues regarding which specific body of law might rule the operation of such satellite systems. It is worth mentioning, in a very short but essential sense, what Global Navigation Satellite System (herein after GNSS) refers to. GNSS refers to a constellation of satellites providing signals from space that transmit positioning and timing data to GNSS receivers. Providing global coverage, GNSS includes Europe’s Galileo, the USA’s GPS, Russia’s GLONASS and China’s BeiDou Navigation Satellite System
Building and Animating User-Specific Volumetric Face Rigs
No full textCurrently, the two main approaches to realistic facial animation are 1) blendshape models and 2) physics-based simulation. Blendshapes are fast and directly controllable, but it is not easy to incorporate features such as dynamics, collision resolution, or incompressibility of the flesh. Physics-based methods can deliver these effects automatically, but modeling of muscles, bones, and other anatomical features of the face is difficult, and direct control over the resulting shape is lost. We propose a method that combines the benefits of blendshapes with the advantages of physics-based simulation. We acquire 3D scans of a given actor with various facial expressions and compute a set of volumetric blendshapes that are compatible with physics-based simulation, while accurately matching the input scans. Furthermore, our volumetric blendshapes are driven by the same weights as traditional blendshapes, which many users are familiar with. Our final facial rig is capable of delivering physics-based effects such as dynamics and secondary motion, collision response, and volume preservation without the burden of detailed anatomical modeling.

Semantic parametric body shape estimation from noisy depth sequences
No full textThe paper proposes a complete framework for tracking and modeling articulated human bodies from sequences of range maps acquired from off-the-shelf depth cameras. In particular, we propose an original approach for fitting a pre-defined parametric shape model to depth data by exploiting the 3D body pose tracked through a sequence of range maps. To this goal, we make use of multiple types of constraints and cues embedded into a unique cost function, which is then efficiently minimized. Our framework is able to yield compact semantic tags associated to the estimated body shape by leveraging on semantic body modeling from MakeHuman and L1 relaxation, and relies on the tools and algorithms provided by the open source Point Cloud Library (PCL), representing a good integration of the functionalities available therein.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Logical framework for information retrieval and conservation project. Geo-referential querying in integrated catalogues and notified cultural heritages
No full textShort and full papers from the Sixth International Cultural Heritage Informatics Meeting, ichim01 in Milano, Italy. Sections of the volumes reflect the major themes discussed at ichim01: Technology, Society / Impact, Design and Evaluation, and Tools and Systems.
The International Cultural Heritage Informatics Conference (ichim) has been held every two years since 1991, and each time it has had a distinctive character, reflecting the changes in technology and the maturation of cultural informatics in the intervening years. The Millennial meeting of ichim in 2001 is no exception. At the meetings in Milan, Italy in September 2001, ichim grew beyond the specific technologies of delivery of interactive multimedia - videodisk, CD and the web À whose novelty had captured center stage at some previous conferences, and focused instead on the intersection between cultural knowledge representation and users experience. After a decade, we may say that ichim is reaching a point of maturity where the technology per se is less of an issue and how the technology and content can be effectively delivered to various real audiences is the major concern. And what an exciting place that is!
These Proceedings reflects the range and depth of issues in cultural heritage informatics today. Like the conference, it is organized in thematic "tracks" devoted to technology, society, design and evaluation, and applications. The conference itself included keynote addresses, panels, site visits, open discussions and demonstration sessions in addition to the full conference papers and shorter "poster" papers included here. Although print volumes can never capture the essence of a meeting, these books do justice to the issues that were debated and helps define the areas for future research
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
The role of veterinary medicine in wildlife rehabilitation worldwide
No full textThe increased role of human activity is creating new and growing conservation problems and new diseases that affect the long-term survival of endangered free-range and captive species, as well as dangerous impacts on ecosystems and human health. Veterinarians not only have extensive education in comparative medicine (rather than focusing on a single species), but are also highly trained in recognizing, diagnosing, and understanding the impact of diseases on public health, as well as individuals, populations, and entire ecosystems. Their skills and experience make them valuable key players in the planning, implementation and effective promotion of projects which imply both the technique of conservation of all levels of biological diversity outside their natural habitats through different techniques like zoo, captive breeding, aquarium, botanical garden, and gene bank and the technique of conservation of a species in its natural habitat and the maintenance and recovery of viable population of species in their original place. In parks and zoological gardens, priority is now given to the main goals: the conservation of the world's fauna and flora and the protection of animal welfare. Today, animal welfare can be scientifically assessed to determine the quality of life of humans, in which behavioral assessment and behavioral enrichment are the main tools [1].
Wildlife rehabilitators provide a number of important services in their communities. Wildlife rehabilitation can improve the welfare of hundreds, thousands of animals, and in larger centers up to ten thousand animals a year. Due to very strict release criteria and the progressive nature of many of the diseases and injuries seen in rehab centers, more than half of the animals admitted to rehab centers are not released. Humane euthanasia of animals unsuitable for release may have the greatest impact on the welfare of individual animals. Without this service, severely ill animals will experience prolonged suffering and eventually death in the wild or at the hands of humans. Removing wild animals from common use not only improves their well-being, but can also have a positive impact on public health. Without the presence of licensed wildlife treatment centers, many well-meaning but unprepared citizens would attempt to care for wild animals in their own homes, potentially resulting in injury to the public, transmission of zoonotic diseases, or transmission of infectious diseases to and from pets. Wildlife centers also play an important role in educating the public about the importance of conservation and how to coexist peacefully with their wild neighbors. They can also contain vast amounts of data that can contribute to biological and veterinary research. Wildlife rehabilitators are often the first to spot infectious disease outbreaks or toxins affecting wild populations and can alert governments and regulators. Veterinarians can make a great contribution to this area, as well as learn a lot through collaboration with rehabilitators, biologists and those who can teach how the natural environment functions, and in particular how people can manage their behavior and ecosystems in order to live well
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
