Numerical model application for the restoration of the Racconigi Royal Park (CN, Italy)     

Paolo Cavagnero  Roberto Revelli   《Journal of Cultural Heritage》2009,10(4):514-519

After years of neglect and an almost complete lack of maintenance, the Racconigi Royal Park was in an inevitable and widespread state of decay. This decay also involved the waterways that were designed in the nineteenth-century by Xavier Kurten (1811–1840). The seasonal lack of water and the agricultural needs of the farms around the Park made it necessary, during the planning stage of the restoration project, to consider the practicability and the effectiveness of some measures that were conceived to optimize the operation of the restored waterways, without altering the historical structure of the system. The realization of a hydraulic numerical model of the system, which is briefly illustrated in the first part of this case study, resulted to be the most suitable tool to study different possible solutions of the problem. The model simulations in fact helped the restorers put into effect the right remedies to favour the correct flow of the water, to make the whole historical system more efficient and to make its future maintenance easier.  相似文献

A low-cost method for estimating energy expenditure during soccer refereeing     

Luca Paolo Ardigò  Johnny Padulo  Andrea Zuliani  Carlo Capelli 《Journal of sports sciences》2015,33(17):1853-1858

This study aimed to apply a validated bioenergetics model of sprint running to recordings obtained from commercial basic high-sensitivity global positioning system receivers to estimate energy expenditure and physical activity variables during soccer refereeing. We studied five Italian fifth division referees during 20 official matches while carrying the receivers. By applying the model to the recorded speed and acceleration data, we calculated energy consumption during activity, mass-normalised total energy consumption, total distance, metabolically equivalent distance and their ratio over the entire match and the two halves. Main results were as follows: (match) energy consumption = 4729 ± 608 kJ, mass normalised total energy consumption = 74 ± 8 kJ · kg^?1, total distance = 13,112 ± 1225 m, metabolically equivalent distance = 13,788 ± 1151 m and metabolically equivalent/total distance = 1.05 ± 0.05. By using a very low-cost device, it is possible to estimate the energy expenditure of soccer refereeing. The provided predicting mass-normalised total energy consumption versus total distance equation can supply information about soccer refereeing energy demand.  相似文献   

The influence of dovetailed cross beams on the dimensional stability of a panel painting from the Middle Ages     

Ottaviano Allegretti  Marco Fioravanti  Paolo Dionisi-Vici  Luca Uzielli 《文物保护研究》2014,59(4):233-240

This paper describes experiments carried out to determine the influence of dovetailed cross beams on the dimensional stability of a panel painting from the Middle Ages. Besides a serious cup (transverse distortion), the panel featured an unusual longitudinal distortion, a bow, mostly originating from bending in the proximity of the middle cross beam. Because of its localized occurrence, bending appeared to be caused by the crossbeam somehow pushing on the walls of its channel. Thanks to the cooperation offered by the curator and the restorer, some non-damaging tests were performed to measure the distortions of the panel, with and without the cross beams, after conditioning it in different climates. Processing and analysis of the measurement results demonstrated that the bow of the panel increases as the wood moisture content decreases. This led to the conclusion that the bow is actually produced by forces exerted by the cross beam along the panel's length, according to a mechanism named thrust transformation. By this mechanism the cross beam partly transforms the panel's tendency towards cupping, into a bow distortion.  相似文献   

Students' transition into higher education: The role of self-efficacy,regulation strategies,and academic achievements     

Shanyan Lin  Sofia Mastrokoukou  Claudio Longobardi  Paolo Bozzato  Francesca Giovanna Maria Gastaldi  Martina Berchiatti 《Higher Education Quarterly》2023,77(1):121-137

Transition into higher education (HE) has received increased interest in recent years, since it represents a challenging period for students. The aim of this study was to further understand the associations between self-efficacy, academic achievements, and regulation in first-year university students during their transition into HE. The convenience sample consisted of 374 first-year university students (230 females, 61.5%), aged from 18 to 33 (M = 19.86, SD = 1.51) and recruited from an Italian university. Self-efficacy was assessed using the Motivated Strategies for Learning Questionnaire; regulation strategies were assessed with the Inventory of Learning Patterns of Students; and a self-reported grade point average was taken as an indicator of each student's academic performance. Result shows that students' self-efficacy was positively associated with self-regulation and negatively associated with a lack of regulation. Students with higher self-efficacy and self-regulation strategies had better academic performance. Female students performed better in academic activities and adopted more external regulation strategies. The findings represent an opportunity for university institutions to consider the interventions they provide to first-year students in order to facilitate the successful transition from secondary school; they also provide researchers with further knowledge about the effect of self-efficacy, and regulation strategies on students' adjustment to HE.  相似文献   

Passengers information in public transport and privacy: Can anonymous tickets prevent tracking?     

Gildas Avoine  Luca Calderoni  Jonathan Delvaux  Dario Maio  Paolo Palmieri 《International Journal of Information Management》2014

Modern public transportation companies often record large amounts of information. Privacy can be safeguarded by discarding nominal tickets, or introducing anonymization techniques. But is anonymity at all possible when everything is recorded? In this paper we discuss travel information management in the public transport scenario and we present a revealing case study (relative to the city of Cesena, Italy), showing that even anonymous 10-ride bus tickets may betray a user's privacy expectations. We also propose a number of recommendations for the design and management of public transport information systems, aimed at preserving the users’ privacy, while retaining the useful analysis features enabled by the e-ticketing technology.  相似文献   

Improving the design of squat machine using motion capture and virtual prototyping   总被引：1，自引：0，他引：1  

Lorenzo Mariti  Pier Paolo Valentini 《Sports Engineering》2011,14(2-4):73-84

Dynamic squat is one of the most executed fitness exercise. Its use is widespread both for rehabilitation and training purposes. Several typologies of the squat exercise can be performed. The most important are the front squat and the back squat. In the front squat the barbell is held in front of the body across the clavicles and deltoids, while in the back squat exercise the bar is held on the back of the body at the base of the neck. In this paper we will refer to dynamic back squat. The squat exercise can be performed with or without the help of a machine that has the scope of guiding the person during the movement and ensuring his stability and safety. The use of this type of machine is often necessary when the workout is heavy and the risk of incorrect exercise and injuries is high. On the other hand, the rigid structure of this device often overconstrains the lifting movement. From all these observations, the purpose of the paper is to discuss an alternative design of a mechanism able to maintain the advantage to allow a free-body execution and to preserve the safety of the athletes as well. The proposed mechanism has been designed starting from an anthropometric study on the squat movement. This has been performed by using a motion capture system and applying computer-aided engineering techniques. The design activity started from the experimental investigation of the trajectory of the barbell during the natural execution of the unrestricted back squat exercise. The tests have been performed on several subjects with different mass, anthropometry and gender. In a second phase, the data have been processed and analyzed and a specific mechanism, able to reproduce the natural trajectories, has been synthetized. Finally, the design and optimization of the entire structure has been performed through the use of virtual prototyping techniques.  相似文献

An interpretative model from the elasticity theory to explore knowledge integration in new product development     

Angelo?Corallo  Mariangela?Lazoi  Giustina?SecundoEmail author  Paolo?DePaolis 《知识管理研究与实践》2016,14(4):478-488

This paper presents a conceptual model to explore the knowledge integration (KI) practices of internal and external company actors involved in the New Product Development (NPD) process of the aerospace industry. The model is based on the linkage of elasticity principles, particularly Hooke’s Law, to Knowledge Management theory. KI practices are considered as a force pushing the NPD process and are metaphorically described as the spring addressed by Hooke’s law. The integration of the knowledge of internal and external company actors impacts NPD, reducing the dimensions of the whole process, in terms of phases, through the application of the concurrent engineering approach. The whole NPD process is improved in terms of the reduction of uncertainty and complexity, and with an ‘integrated energy’ that sustains the pressure of the fast-changing competitive environment. The model is explored to provide an interpretation of the conceptualisation phase of a new aerospace product development process. Qualitative data were collected and analysed. Insights regarding the applications of the model and the theoretical implications are also provided for applications in other industries.  相似文献   

Network time for the European Higher Education Area     

Rosaria Lumino  Paolo Landri 《Educational Philosophy and Theory》2020,52(6):653-663

Abstract

In this article, we discuss the process of standardization of Higher education (HE) initiated by the Bologna Process bringing to the forefront the temporal politics of the standardization of European Higher Education Arena (EHEA). Empirically, we perform a comparative review of the Scorecards indicators at the base of the Bologna Process monitoring project. We argue that the fabrication of EHEA could be seen as the installation of new time-space ‘time’ and ‘space’ appear inevitably intertwined. Instead of being a simple addition, the time space of EHEA interferes with the multiple time spaces of educational institutions and is characterized by being a network time, an unbroken and fragmented temporality sustained, enacted through, and controlled by the fluidity and the malleability of standards. They change recurrently over time, playing with different rhythms. What emerges is an overall arrhythmia that maintains the field permanently in tension. This reconfigures temporality as intrinsically manifold: as multiple and heterogeneous. Moreover, the temporal politics of standards reconfigures perception of past, present and especially future. The current state of implementation is constantly being (re)shaped in relation to the present and future performances, where’s one today level of EHEA targets achievement forms the basis for improvement tomorrow. In this scenario, assessing standards and headline targets become a policy instrument for synchronizing the countries performances, by locating them in a temporal framework that encodes future-oriented dispositions.  相似文献
