As a new type of bolt, the polycystic aeration bolt has a broad application prospect in soft soil area; however, its design and production are still in the stage of constant exploration and improvement. From the perspective of bolt material and engineering cost, the important components of the polycystic aeration bolt were analyzed by combination with the existing bolt models, and a new structural design scheme of a kind of polycystic aeration bolt which can be used in practical engineering was presented in this paper. Then, the stress and failure mode of this bolt were discussed, and the theoretical equation of the bearing capacity was derived by using the elastic-plastic theory. In addition, the assembly and fabrication technology of this bolt in practical foundation pit engineering was described in detail. Finally, the field pull-out test of the polycystic aeration bolt was carried out, and the test results were compared with those of the conventional grouting bolt, which indicated that this new bolt has a greater advantage in bearing capacity than the conventional grouting bolt, verifying the feasibility of the structural design scheme of the polycystic aeration bolt proposed in this paper.

The accumulator can store the energy in high capacity, and the super capacitor can charge and discharge in high power. The mixed power source composed by the accumulator and super capacitor not only has the characteristics for both of them but also meets the high-power requirement of high capacity and peak value. How to perform the equalizing charging for multiple power packs is a emphasis in the industry currently. On the basis of analysis for multiple equalizing charging methods, a new type of design scheme based on DC/DC and switch matrix is raised in this project, the thinking of intermittent charging mode is adopted and four BCAP0350 is served as the charging sample to perform the charging and discharging experiment as well as verify the composite charging design scheme is provided with the feasibility.

Partial Division

The author in the paper analyzes the penal system of the French Penal Code of 1810 (Code pénal de 1810), bearing in mind the influence this Code and its penal system had on the further development of French and European substantial criminal law. The fact that the Napoleonic Penal Code of 1810, with its later modifications and additions, remained in force for 184 years, speaks in favor of this. In this paper the penal system of the Code of 1810 is exhibited according to the original system of the Code. The tri‐partial division of both criminal acts and penalties was a novelty in the European criminal law. Given the fact that this was a Code promulgated 21 years after the Bourgeois revolution, the author compares the penal system of this Code to the penal system of the first revolutionary Penal code of 1791, but also with penalties that were used in the “Old regime” (Ancien régime). Based on the data published in bills and literature, the author gives a detailed analysis of all penalties contained in the Penal Code of 1810. Thereby, the key criminological problems caused by the practical application of these penalties is pointed out.

The need to simultaneously optimize the structural design properties, and attain a satisfactory vibroacoustic performance for composite structures, has been a challenging task for modern structural engineers. This work is aimed at developing a statistical energy analysis (SEA) based numerical scheme for computing the optimal design parameters of each individual layer of layered curved shells having arbitrary complexities and layering. The main novelty of the work focuses on the computation of SEA properties for curved composite shells and derive the sensitivities of the acoustic transmission coefficient, expressed through the computed SEA properties, with respect to the structural design characteristics to be optimized. A wave finite element approach is employed to calculate the wave propagation constants of the curved shell. The calculated wave constants are then applied to compute the vibroacoustic properties for the curved shell using a SEA approach. Sensitivity analyses are conducted on the vibroacoustic properties to estimate their response to changes in the structural properties. Gradient vector is then formulated and hence the Hessian matrix, which is employed to formulate a Newton-like optimisation algorithm for optimizing the properties of the layered composite shell. The developed scheme is applied to a sandwich shell; optimal design parameters of [Formula: see text] and [Formula: see text] are obtained for the facesheet and the core of the shell whose base parameters are [Formula: see text] and [Formula: see text], respectively. This simultaneously optimizes the structure with maximum stiffness and minimum mass and attains a satisfactory dynamic performance for acoustic transmission through the sandwich shell. The principal advantage of the scheme is the ability to accurately model composite panels of arbitrary curvature at a rational computational time.

Suitable Technique

In the present paper, a dynamic version of Water Strider Algorithm (WSA) is proposed. The WSA as well as the Dynamic Water Strider Algorithm (DWSA) are applied to minimize the weight of several skeletal structures. WSA is a nature-inspired metaheuristic that mimics the territorial behavior, intelligent ripple communication, mating style, feeding mechanisms, and succession of water strider insects. The efficiency of these algorithms is tested by optimizing different truss and frame structures subject to multiple loading conditions and constraints. Comparing the results obtained by DWSA with those of other methods it becomes evident that DWSA is a suitable technique for optimizing the structural design and minimizing the weight of structures while fulfilling all constraints.
