Independent friction-restitution approach to analyze anomalies in normal kinematic restitution in oblique impact
2021
Abstract Oblique impact between rigid bodies is usually described in terms of the coefficients of normal and tangential restitution. When the contact between bodies occurs under elasto-plastic conditions, the normal coefficient of restitution can be ordinarily taken as essentially constant. Several anomalous results reported by Louge and Adams (Anomalous behavior of normal kinematic restitution in the oblique impacts of a hard sphere on an elasto-plastic plate. Phys. Rev. E 65 (2002) 021303), however denoted a significant variation of this coefficient with the incidence angle under certain conditions. This anomalous behavior is interpreted here within the independent friction and restitutio…
Analysis of oblique rebound using a redefinition of the coefficient of tangential restitution coefficient
2013
Abstract A redefinition of the coefficient of tangential restitution based on the separation of friction and restitution effects is presented. Using this modified coefficient of tangential restitution and the usual definitions of the coefficients of normal restitution and sliding friction, a description of oblique impacts in both stick and slip regimes is obtained. This, description, which is tested with available rebound data in literature, avoids sharp (apparent) variations in the coefficient tangential restitution with impact angle and can justify anomalous results reported by Calsamiglia et al. (1999) .

Digital Restitution of Cultural Goods: In Search of a Working Model
2023
AbstractThe paper deals with the problem of digital restitution of art to post-colonial and postdependency countries. A new model of digital restitution composed of two elements: creation of a digital copy with a NFT attached and creation of new property right in a physical and digital object has been proposed. A system of balances between the rights and duties based on the prior user concept has been developed.
The Promise and Perils of Urban Land Restitution in Latvia
2021
ABSTRACT∞ In this article we address the transitional justice policy of restitution in kind with a case study of urban land reform in Latvia. Contributing to scholarship on the challenge of property reforms after generations of dispossession, we examine the economic, social and political meanings of property restitution in this post-Soviet context. Using process-tracing techniques to examine the creation and implementation of Latvia’s policy in the aftermath of independence from the Soviet Union, we illustrate specific challenges of restitution in kind where property changed through the construction of new buildings occupied by tenants. Financial disputes between landowners and tenants map …
The genus Bolbelasmus in the western and southern regions of the Mediterranean Basin (Coleoptera: Geotrupidae: Bolboceratinae)
2016
The Bolbelasmus Boucomont, 1911 species of the western and southern regions of the Mediterranean Basin (Northern Africa, Iberian Peninsula and France) are revised. The following three new species are described: Bolbelasmus brancoi Hillert & Král sp. nov. and Bolbelasmus howdeni Hillert & Král sp. nov., both from Spain and Gibraltar, and Bolbelasmus nikolajevi Hillert, Arnone, Král & Massa sp. nov. from Egypt, Libya and Tunisia. Bolbelasmus vaulogeri (Abeille de Perrin, 1898) stat. restit. is removed from synonymy with B. bocchus (Erichson, 1841) and reinstated as a separate species. Bolbelasmus romanorum Arnone & Massa, 2010 is considered a junior subjective synonym of B. vaulogeri. Lectoty…
A 3D REWORKING OF THE URBAN TRANSFORMATIONS OF PALERMO IN RECENT HISTORY FOR A HYPOTHESIS OF A "CITY MUSEUM" BASED ON DIGITAL VISUALIZATIONS
2021
Abstract. The objective that drives this research is given by a multitude of information which, in addition to the contribution of technology, allows us to study, analyze, verify and remodel the sites, monuments and evolutions of the city through graphic processes of perspective restitution that start from the analysis of historical photos. The drawing methods, the digital graphic rendering and through the aid of geometric techniques, contribute to the reconstruction of projects and architectures that are now lost, this is possible thanks to the methods of perspective, axonometry and three-dimensional restitution.This remarkable photographic heritage belonging to Palermo, but also to any ot…
BEFORE THE EARTHQUAKE: RECONSTRUCTION AND PRESENTATION OF LOST SITES AND BUILDINGS
2021
Abstract. The paper presents the results of a research aiming at proving the efficacy of perspective restitution from photos for the reconstruction of buildings and sites that disappeared in the past century. The case study is the town of Messina, sited at the north-eastern corner of Sicily (Italy), facing the homonymous strait that divides Sicily from the Italian peninsula; in 1908 Messina and Reggio Calabria, at the opposite side of the strait, were levelled to the ground by a powerful earthquake, followed by a tsunami.No building or monument survived the destruction: a new town with the same name took the site of Messina. Except for few strongly reshaped buildings, the memory of the stre…

Mathematical modeling of a vehicle crash test based on elasto-plastic unloading scenarios of spring-mass models
2011
Published version of an article in the journal: The International Journal of Advanced Manufacturing Technology. Also available from the publisher on SpringerLink: htp://dx.doi.org/10.1007/s00170-010-3056-x This paper investigates the usability of spring which exhibit nonlinear force-deflection characteristic in the area of mathematical modeling of vehicle crash. We present a method which allows us to obtain parameters of the spring-mass model basing on the full-scale experimental data analysis. Since vehicle collision is a dynamic event, it involves such phenomena as rebound and energy dissipation. Three different spring unloading scenarios (elastic, plastic, and elasto-plastic) are covered…
