Summary: This article describes a new procedure for automated generation of two-dimensional locally refined quadrilateral meshes of gear drives, including steps such as base mesh generation, refinement of selected elements, and mesh quality enhancement. The procedure is capable of automatically identifying and refining areas of the gear that are subjected to elevated stress gradients.

Summary: The study aimed to develop a simple methodology to estimate national wheat yields that can be applied to any country and crop by correlating climate data with national wheat production. Statistical models were built using the climate data from the most representative grid cell to estimate trend-corrected national wheat yields, and the models were validated in Brazil, France, and Russia with a small margin of error. This approach allows for early predictions of national crop yields during a cropping season.

Summary: This paper proposes a simple and ready-to-use seismic classification scheme for nonstructural elements, which can be applied to both newly designed and existing elements. The classification helps identify the best typology for the site and building, and prioritize interventions for existing elements.

Summary: This study proposes a 2D end-to-end seismic inversion method based on domain adaptation to address the issues of poor spatial continuity and weak generalizability in traditional methods. Experimental results demonstrate that the proposed method outperforms other methods on both synthetic and real seismic data.

Summary: This paper proposes a new direct Displacement-based procedure of nonlinear static analysis for multi-storey reinforced concrete buildings, aiming to exclude floor plastic mechanism formation regardless of torsional sensitivity or high asymmetry. The proposed methodology controls both the seismic inelastic angular deformation demands of building floors and the actual seismic floor inelastic displacement demands, taking into account floor-diaphragm coupling, higher mode contributions, and P-Delta effects. The procedure involves applying enforced-displacements on the floor-diaphragms and performing a set of sixteen final nonlinear static analysis cases to approximate seismic demand resulting from nonlinear response history analyses.

Summary: This article presents a general and simple procedure for designing VEs capable of enforcing contrast sources with desired properties. The proposed procedure is computationally straightforward and stable, as it does not require an explicit inversion and regularization process. The design approach is tested in the case of VE enforcing circularly symmetric contrast sources, and the corresponding inversion procedure is assessed using both simulated and experimental data.

Summary: Performance-based design, envisioned in the early 1990s, has become a key concept in seismic design. However, practical approaches for integration into building codes are lacking, particularly the correlation between structural response parameters and expected monetary losses. This paper aims to provide a formulation for a practical loss-based approach.

Summary: A simple mesh-free method is proposed for solving 2D and 3D elasticity problems in potentially heterogeneous media. The method discretizes the solution domain and boundary separately, using regular nodal grids and boundary points. The method also introduces the concept of clouds, where each node corresponds to a cloud containing adjacent nodes.

Summary: The paper discusses a procedure for evaluating seismic risk on historic and/or cultural structures, utilizing additional economic parameters to consider the unique aspects of these buildings. The current approach, regulated by Italian codes and calibrated for residential buildings, is deemed inadequate for analyzing cultural buildings, highlighting the need for a specific and in-depth analysis.

Summary: A new method for seismic design is proposed to control earthquake damage to structures. By correlating the design story drift with a selected damage index value, the method aims to achieve the prescribed level of earthquake damage. Nonlinear dynamic analyses and regression analysis show the feasibility of this approach for specific types of buildings.

Summary: This study extends the probabilistic seismic landslide hazard analysis (PSLHA) by utilizing the results from probabilistic seismic hazard analysis (PSHA) to account for uncertainties in ground motions and soil strengths. Two simplified methods are proposed and evaluated, with one demonstrating better performance. The selected method is applied to assess the probabilistic seismic landslide hazard in Taiwan's Tsao-Ling area. Seismic landslide hazard maps are then constructed and compared with a deterministic map from the 1999 Chi-Chi earthquake.

Summary: A new enhanced multi-modal pushover procedure, the Multi-Mode Displacement-Based Pushover (MDP) method, is developed for estimating structural demands with higher mode effects considered. Compared to adaptive methodologies, the MDP method requires less computational effort and time cost while maintaining accuracy in predicting critical seismic demands.
