    La notissima vicenda relativa al cd. caso Eternit, conclusasi in sede di legittimità con una declaratoria di estinzione per intervenuta prescrizione dei reati contestati – omissione dolosa di cautele, aggravata dalla verificazione del disastro (art. 437, co. 2, cp) e disastro cd. innominato (art. 434, co. 2, c.p.) –, ha posto all'attenzione anche del “grande pubblico” le complesse problematiche sottese all'individuazione del dies a quo della prescrizione penale. Nel presente contributo, l’Autore sottopone a vaglio critico le decisioni di merito e legittimità intervenute nel processo Eternit, con particolare riguardo alla questione dell’individuazione del dies a quo della prescrizione per il delitto di disastro cd. innominato (art. 434, co. 2, c.p.), concludendo nel senso di condividere le conclusioni della Corte di cassazione, sia pur alla luce di un diverso percorso argomentativo

    A study on spline quasi-interpolation based quadrature rules for the isogeometric Galerkin BEM

    Full text link
    Two recently introduced quadrature schemes for weakly singular integrals [Calabr\`o et al. J. Comput. Appl. Math. 2018] are investigated in the context of boundary integral equations arising in the isogeometric formulation of Galerkin Boundary Element Method (BEM). In the first scheme, the regular part of the integrand is approximated by a suitable quasi--interpolation spline. In the second scheme the regular part is approximated by a product of two spline functions. The two schemes are tested and compared against other standard and novel methods available in literature to evaluate different types of integrals arising in the Galerkin formulation. Numerical tests reveal that under reasonable assumptions the second scheme convergences with the optimal order in the Galerkin method, when performing hh-refinement, even with a small amount of quadrature nodes. The quadrature schemes are validated also in numerical examples to solve 2D Laplace problems with Dirichlet boundary conditions

    Enhancing the graduates’ employability and career development through building information modelling intensive training

    Building Information Modelling (BIM) is an emerging technological process which highly promotes a better collaborative working environment in the Architecture, Engineering and Construction (AEC) industry. It is essential that the Higher Education (HE) sector innovates its education system to integrate between different disciplines in the AEC industry to encourage the adoption of BIM. In conjunction with this, BIM Intensive Training was conducted for a selected number of final year undergraduate students at Universiti Teknologi Malaysia. They were assigned a real time construction project, utilizing BIM software applications for model authoring, model review, 4D modelling and project coordination. It was observed that the participants were able to overcome various challenges through information sharing and team collaboration. A BIM coordination workflow was produced during the training to assist them in organizing their work. Although their existing knowledge of BIM and their skills using the software applications were quite limited, they were capable in learning expeditiously as the assignment provided them with real-world problems. A year after the training, more than half of the participants agreed that the training had helped them to secure their employment and excel in their current involvements in BIM-based projects. However, due to the current scenario many firms are yet to embrace BIM, there are participants who could not utilize the training. Hence, the establishment of a dynamic and continuous collaboration between professionals and HE sector is the way forward in transforming the traditional structure of AEC industry into a more collaborative and technological approach

    An estimation of sediment yield using universal soil loss (USLE) and rating curve in Barat Daya District of Penang, Malaysia

    Sediment yield estimation in rivers at the regional or local scale is very important especially in term of managing the water resources in the catchment area. The sediment yield usually calculated either from direct measurement of sediment concentration in rivers or from sediment transport equation at a particular outlet point in the catchment. A total of 19 rivers were selected as sampling sites located at the Barat Daya District of Penang. The Universal Soil Loss Equation (USLE) was used to estimate the sediment yield in the study area by integrating with the Geographic Information System (GIS) to generate maps of the USLE factors, which are rainfall erosivity (R), soil erodibility (K), slope length and steepness (LS), crop management (C), and conservation practice (P) factors. A sediment rating curves of the study area was developed to verify the accuracy as well as comparison to the sediment yield estimated by USLE. The results show good correlation between the sediment yield estimated by USLE and observed data (r2 is 0.62). The sediment yield estimated in the year 1974 was 1300 ton/km2/year, 1984 was 1921 ton/km2/year, 2004 was 1919 ton/km2/year and 2012 was 2336 ton/km2/year. Based on the land use analysis, agricultural activity was dominant in the Barat Daya area and contributes much of the sediment into the river system

    d-Wave Spin Density Wave phase in the Attractive Hubbard Model with Spin Polarization

    Full text link
    We investigate the possibility of unconventional spin density wave (SDW) in the attractive Hubbard model with finite spin polarization. We show that pairing and density fluctuations induce the transverse d-wave SDW near the half-filling. This novel SDW is related to the d-wave superfluidity induced by antiferromagnetic spin fluctuations, in the sense that they are connected with each other through Shiba's attraction-repulsion transformation. Our results predict the d-wave SDW in real systems, such as cold Fermi atom gases with population imbalance and compounds involving valence skipper elements
