A Maximal-Space Algorithm for the Container Loading Problem
2008
In this paper, a greedy randomized adaptive search procedure (GRASP) for the container loading problem is presented. This approach is based on a constructive block heuristic that builds upon the concept of maximal space, a nondisjoint representation of the free space in a container. This new algorithm is extensively tested over the complete set of Bischoff and Ratcliff problems [Bischoff, E. E., M. S. W. Ratcliff. 1995. Issues in the development of approaches to container loading. Omega 23 377–390], ranging from weakly heterogeneous to strongly heterogeneous cargo, and outperforms all the known nonparallel approaches that, partially or completely, have used this set of test problems. When …

Landform classification: a high-performing mapping unit partitioning tool for landslide susceptibility assessment—a test in the Imera River basin (no…
2022
In landslide susceptibility studies, the type of mapping unit adopted affects the obtained models and maps in terms of accuracy, robustness, spatial resolution and geomorphological adequacy. To evaluate the optimal selection of these units, a test has been carried out in an important catchment of northern Sicily (the Imera River basin), where the spatial relationships between a set of predictors and an inventory of 1608 rotational/translational landslides were analysed using the multivariate adaptive regression splines (MARS) method. In particular, landslide susceptibility models were prepared and compared by adopting four different types of mapping units: the largely adopted grid cells (PX…
Influence of lateral load distribution in estimation of target displacement and capacity demand by pushover analysis
2010
Two simplified adaptive load patterns for conservative estimation of seismic demand in 2D frames by pushover analysis are presented. The influence of load pattern in assessment of target displacement and distribution of demand along the height of the structure is investigated by comparing results of non linear history analysis, and non linear static analysis for eccentric braced frames. Numerical analyses show that the proposed load patterns provide safe estimation of the seismic response more accurately than load patterns proposed by seismic code.
The Power of the Young Town
2017
In Italy, after the Second World War, according to Fanfani and Tupini’s laws (1949), INA-casa and its procuring entities’ ventures made a motor of urban renewal from the enthusiasm and the commitment of many entrepreneurs and public administrators. In Palermo, the agricultural lands began to include new neighbourhoods that quickly merged with the historic and nineteenth-twentieth century centre. In the fifties, between the town and its geographic limits (the mountains of the Corona dei Colli) a beltway has been hypothesized. It was a founding board (Culotta, 2005). In the sixties, it was the spine of an expanding urban fabric that absorbed citrus groves, vineyards, olive groves, field of fl…
I caratteri dell'architettura resiliente adattiva. Invarianti compositive del progetto: 1990-2020
2023
La Tesi di Dottorato “I caratteri dell’architettura resiliente adattiva. Invarianti compositive del progetto: 1990-2020” si propone di affrontare il rapporto fra l’architettura resiliente adattiva e le invarianti compositive del progetto attraverso l’influenza che tale rapporto ha sull’evoluzione e l’innovazione dei caratteri dell’architettura. In un momento storico in cui termini come resilienza e innovazione ricoprono un ruolo cruciale nell’esplorazione delle potenzialità della ricerca e costituiscono un requisito indispensabile per la programmazione del prossimo futuro, si è ritenuto opportuno ricondurre l’attenzione della ricerca dottorale al cuore della disciplina del progetto di archi…
A Harris-based Region Detector on a Computational Grid
2007
This paper introduces a new Harris-based feature detector algorithm, characterized by no parameters tuning to detect region of interest. Preliminary results show that the proposed methodology returns good results with respect to standard detectors which need a set of parameters. An uncommon parallel implementation of the proposed algorithm is presented to support the high computational workload which is required to avoid the approximation of the results. Our parallel approach differs from the conventional one because an internal scheduler, based on the expected running time, is used to balance the data distribution on a client-server model. The aim of this paper is also to underline the adv…
A fast BEM for the analysis of plates with bonded piezoelectric patches
2010
In this paper a fast boundary element method for the elastodynamic analysis of 3D structures with bonded piezoelectric patches is presented. The elastodynamic analysis is performed in the Laplace domain and the time history of the relevant quantities is obtained by inverse Laplace transform. The bonded patches are modelled using a semi-analytical state-space variational approach. The computational features of the technique, in terms of required storage memory and solution time, are improved by a fast solver based on the use of hierarchical matrices. The presented numerical results show the potential of the technique in the study of structural health monitoring (SHM) systems.
Evaluation through adaptive model (ATC) in the levels of thermal comfort in summer in offices in Mediterranea locations.
2014
The design of the building-plant system in the case of office buildings has rarely considered the adaptive model of comfort almost always limited to the control of temperature and humidity and only in some cases of PMV and PPD. Specifically when the building interacts with a climate characterized by high values of external temperature and humidity for long periods, and with high solar radiation in the presence of large glazed areas, it is crucial to take into account relevant aspects of the principle of thermal adaptation. The long stay of the occupants in an air-conditioned environment leads, at the request of colder temperatures very distant from those indicated by the criteria of accepta…
A Sustainable and Zero Energy Healthcare Facility in Mozambique
2016
Sustainable urban development, especially in economically disadvantaged regions, has increasingly become a major strategic priority. New settlements and urban regeneration programs have to improve the quality of social life, promote economic growth, increase environmental protection practices, and ensure the appropriate use of local resources. In that framework, a well-structured healthcare service is commonly conceived as vital for urban development. In response, this paper proposes the construction of one such healthcare facility in a deprived urban area in Maputo, Mozambique. Prioritising typical pillars of sustainability, the project’s design considers traditional building typology and …
