Mismanagement in traditional market has made its existence was harmed by modern market. Traditional market is identified as a dirty, crowded, and uncomfortable place to shop. This condition is very different with the condition in modern market. One of the challenges is making the traditional market become a comfort place to shop. The research about crowd modeling in traditional market is being done...
The underwater particular structure cover system is discovered the connecting bolt had spLit by impact. It brought to the product normal using a certain security risk. In the paper, estabLish the mathematical model of fluid-cover structure coupLing, and obtain the equations between fluid and cover system structure. Using FEM software shows that the study and model of this paper has some reference...
This paper is aimed to model behavior of a magnetorheological (MR) damper under impact loading through polynomial approach. The polynomial model is developed based on curve fitting from experimental results and consists of a three regions namely fluid locking, positive and negative acceleration regions. The experimental results which have been performed using impact test apparatus are evaluated in...
The ability to navigate a fluid environment using only hydrodynamic information without visual or acoustic cues represents a technical challenge with broad utility for numerous commercial, military, and scientific purposes. Here we report the successful design, numerical modeling, fabrication, and experimental characterization of a novel, capacitance-based whisker-like artificial sensor for measuring...
To investigate the tail-slap loads on supercavitating projectiles, a simple model for cavity-fluid region is presented based on Logvinovich's Principle. And a series of simulations of fluid - structure interaction (FSI) were done to determine the effects of the slenderness ratio of projectiles on the tail-slap loads. The results show that the impact duration increases as the slenderness ratio increases...
In most structural analysis and fatigue calculations of tank car, researchers would directly input the horizontal inertial force of the fluid on the end wall of the tank as the pressure of the tank wall. In fact, the fluid will influences the distribution of pressure on the tank end wall. Especially when the viscosity of the liquid inside tank is sufficient, the shear force on the tank body will be...
In 3D computer graphics, it has been an important issue to describe a virtual object realistically and show it in a physically correct manner. Unlike the virtual reality(VR), the augmented reality (AR) is an environment containing virtual and real objects simultaneously. However, the difference in motion between the virtual and real objects is obvious, which makes it hard for AR to be realistic and...
