Element Method

It is known that the variable-order infinite acoustic wave envelope element (WEE) must be coupled with finite element method (FEM) by element matching for computing acoustic field radiated from radiators with complex geometric shapes. Therefore, the WEEs have to be reconstructed when the finite elements are refined or changed. To overcome the shortcoming, the element-free Galerkin (EFG) coupled with improved WEE (IWEE) method is presented to compute acoustic problems in the infinite domain. The continuity and compatibility of the acoustic pressure are maintained by IWEE that is composed of a standard WEE and a fictitious finite mesh. A key feature of the method is the introduction of the EFG method which is employed to eliminate the element matching and improve the accuracy of predicted acoustic pressure. The factors that affect the performance of the method are investigated by numerical examples, which include shape function construction, the weight function and the size of the influence domain. The numerical results show that the present method provides more accurate results compared to the coupled FEM-WEE method. The experimental results show that the method is very flexible for acoustic radiation prediction in the infinite domain.

Sport is one of the routine activities that a person does to maintain health, Futsal becomes a trend in the pleasure of young people and also in all circles, futsal is also no different from the game of football because both are played by kicking, the difference is that futsal is very easy not to require a large field and a lot of players. Based on the background of the problems raised from this report, namely how to realize the design of a Futsal Arena (Indoor) Type C equivalent that is creative and has a profit in the district of Upau. The method used to solve this problem is the design method is a method of solving problems with programmatic concepts. The design method is the answer to a problem that will encompass the needs in a building. By focusing on space, shape, function, construction.

AbstractThe topological sensitivity method is an optimization technique used in different inverse problem solutions. In this work, we adapt this method to the identification of plasma domain in a Tokamak. An asymptotic expansion of a considered shape function is established and used to solve this inverse problem. Finally, a numerical algorithm is developed and tested in different configurations.

Digital technology is leading the transformation of business models into sustainable ones, expanding and changing the competitiveness scenario. This paper aims to promote a new sustainable retailer model shaped by contingent free shipping theory and the optimisation of the customer’s journey, enriching the scientific literature by proposing a consumer behavioural model that highlights the contribution of four selected touchpoints to the sustainable transformation of SMEs. The research was elaborated by deploying a framework that presents five analysis methods, namely, an additive function construction, a TOPSIS method, a Spearman rank correlation coefficient calculation, a content analysis and an analytic hierarchy process, which engender the new model. Discovering nine distinguished categories of e-tailers, the sustainable retailer profile was developed and the touchpoint with the greatest contribution to the transformation process was identified. The results of the study allowed the authors to propose the model as a solution to withstand the preponderant negative experience provided by analysed e-tailers to digital buyers, representing the opportunity for SMEs’ sustainable transformation and long-term growth in a competitive, ever-growing market.
