A Bayesian approach to rapid seismic vulnerability assessment at urban scale

The seismic vulnerability of city centers is commonly assessed by extending the study methods applied to single buildings to urban aggregations. This approach is not always applicable at territorial scale, as it is uneconomical in terms of time and costs. An innovative method provides reasonable large-scale a priori estimation of parameters not directly evaluable from the exterior of buildings by elaborating values which can be measured from the outside. Those parameters are treated as continuous variables, by assigning them a suitable probability density function. The Bayesian approach is adopted, which allows the update of initial hypotheses by using new data gathered during on-site surveys. In this regard, a rapid survey form for the on-site data collection is proposed. An example of its application to a façade of a building structural unit in Santo Stefano di Sessanio in L’Aquila province (Italy) is proposed, showing promising preliminary results for buildings belonging to Italian historical centers.     

Multiphase flow simulation through porous media with explicitly resolved fractures

Accurate simulation of multiphase flow in fractured porous media remains a challenge. An important problem is the representation of the discontinuous or near discontinuous behaviour of saturation in real geological formations. In the classical continuum approach, a refined mesh is required at the interface between fracture and porous media to capture the steep gradients in saturation and saturation‐dependent transport properties. This dramatically increases the computational load when large numbers of fractures are present in the numerical model. A discontinuous finite element method is reported here to model flow in fractured porous media. The governing multiphase porous media flow equations are solved in the adaptive mesh computational fluid dynamics code IC‐FERST on unstructured meshes. The method is based on a mixed control volume – discontinuous finite element formulation. This is combined with the P_N+1DG‐P_NDG element pair, which has discontinuous (order N+1) representation for velocity and discontinuous (order N) representation for pressure. A number of test cases are used to evaluate the method's ability to model fracture flow. The first is used to verify the performance of the element pair on structured and unstructured meshes of different resolution. Multiphase flow is then modelled in a range of idealised and simple fracture patterns. Solutions with sharp saturation fronts and computational economy in terms of mesh size are illustrated.     

Biomechanics of coaching maximal instep soccer kick for practitioners

Kicking in soccer has been the subject of scientific research for more than 40 years yet review articles summarizing the biomechanical fundamentals of kick optimization as a guide to coaching are scarcely to be found. The current review article aims to bridge the gap between scientific research into the maximal instep kick (including studies employing 3D motion capture and full-body biomechanical modelling) and the application of such research in coaching. It does so by supplying a scientifically founded, coaching-friendly article explaining identifiable characteristics and motor control sequencing that define this skill. Relevant biomechanical factors are identified in a way that should help coaches better develop training programmes and, at the same time, foster better understanding of the skill among athletes. Such information will contribute to both accelerated skill acquisition and, by concomitant gains in skill efficiency, the development of programmes that minimize risk of injury to athletes during training.

焦竑的学术特点与史学成就

焦竑字弱侯,号澹园,又号漪园,谥文端、文宪,江宁(今南京)人,是晚明最负盛名的学者之一,尤其精于史学.明代史学风气至嘉、万时期丕变,由空疏转向谨严.其中功绩,王世贞之外,则首推焦竑.在焦竑传世的三十余种著作中,史学著作计有《献征录》120卷、《熙朝名臣实录》27卷、《逊国忠节录》4卷、《国史经籍志》6卷、《玉堂丛语》8卷、《皇明人物考》6卷、《京学志》8卷、《词林历官表》3卷等,此外尚有汇录大量考史笔记的《焦氏笔乘》6卷和《续笔乘》8卷等,是明代整个学术发展中非常有影响的人物①.     

赤水河疏浚与川盐(仁岸)入黔

张广泗上疏朝廷,于乾隆十年十一月至十一年闰三月,首浚赤水河,疏通68处险滩,使川盐由四川合江经赤水河到仁岸茅台村,运输路程大大缩短,盐价渐平,对黔人"斗米斤盐"之负担有所减轻,经济效益十分明显.文中还对赤水河源流及遵义知府陈玉(殿)是否参与赤水河疏浚、吴登举之死等问题,均有论述与考辨.
