The Ninth Eurographics Italian Chapter Conference - EG-IT 2011
No full textThe Eurographics Italian Chapter Conference (EG-IT) is the main Italian conference on Computer Graphics. Organized by the EUROGRAPHICS Italian Chapter. The 9th EG-IT will be held in Salerno on the 24th and 25th of November, 2011.
The scientific program of the conference will consist of both invited talks by distinguished speakers and contributions by participants.
Contributed papers will be peer reviewed; accepted papers will be published in the proceedings of the conference by Eurographics and held on the EG digital library.
The theme of 9th EG-IT will be "Toward an augmented world":
contributions will be accepted from all areas of Computer Graphics, Image Processing, Pattern Recognition and Multimedia. Contributions on topics highlighting the potential of Augmented/Mixed Reality in the light of the last generation of digital devices (e.g. sensors equipped smartphones and tablets) or even innovative applications of this technology will be particularly welcome.
The papers of about 4-8 pages should be written in English and should be sent in a printable pdf format
Localized behavior of f-electrons in CeAg: a theoretical study
No full textWe perform self‐consistent linear muffin‐tin‐orbital local‐density‐approximation (LMTO‐LDA) electronic structure calculations for paramagnetic CeAg in the cubic phase to study the hybridization of the Ce f states which is found particularly effective with the Ce d and Ag p states. We also make self‐consistent calculations of the electronic structure of LaAg and use it as the f‐less analog of CeAg to determine quantitatively the localized part of the Ce 4f charge. The latter is identified with the average f‐occupation number nf of the Anderson model
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals

Electronic structure calculations for CeAg
No full textSelf-consistent linear muffin-tin orbital calculations are performed for CeAg. The electronic structure is calculated in the paramagnetic and ferromagnetic phase, for both the cubic and tetragonal symmetry. The presence of hybridization relevant to the Anderson lattice behavior, invoked to interpret the low-temperature properties of this compound, is confirmed. The comparison of the electronic structures of CeAg and of its f-less analog LaAg allows us to determine the localized part of the Ce 4f charge, amounting to ∼ 0.94 e/Ce, to be identified with the average f-occupation number in the Anderson model. A saturation magnetic moment of ≈ 0.78μB is found, which is essentially due to the Ce f electrons
Endoscopic Ultrasound Elastography in Pancreatic Diseases EUS-EG in Pancreatic Diseases
No full textElastography is a new ultrasound technique for tissue characterization, providing a noninvasive modality for the evaluation of tissue stiffness. Different pathologic processes such as cancerization and fibrosis alter tissue elasticity and therefore induce changes in elastographic appearance. The application of elastography to endoscopic ultrasound (EUS) technique allows a better characterization of lesions by the evaluation of tissue stiffness in sites only accessible from the gastrointestinal tract. In addition, the recent introduction of second-generation elastographic techniques (EUS-EG) allows an objective quantitative analysis of tissue strain. In the last years, EUS-EG has been increasingly used in the evaluation of several pancreatic diseases, including neoplasms, and inflammatory processes. Malignant pancreatic lesions are generally harder than adjacent pancreatic tissue, due to the presence of fibrosis and marked desmoplasia. In this setting, EUS-EG demonstrated high accuracy for the differential diagnosis of solid pancreatic tumors. Concerning parenchymal diseases, EUS-EG has been demonstrated to be a useful tool in the diagnosis of chronic pancreatitis and autoimmune pancreatitis. EUS-EG can provide an objective quantization of parenchymal stiffness, having a valuable role during the follow-up for monitoring possible disease progression and the need for medical treatment. We here aimed to review the main applications of EUS-EG in both focal and parenchymal pancreatic disease
