Laterally asymmetric vibrotactile stimuli produce anisotropic or direction-dependent friction force that function as a friction display system [1]. In this study, we showed that laterally symmetric vibrotactile stimuli increase friction perception by a similar principle. We measured the frictional forces between a sliding finger pad and a contactor laterally vibrating at 3 or 5 H. We found that...

Introduction Studying motility of biological objects is an important parameter in many biomedical processes. Therefore, automated analyzing methods via microscopic videos are becoming an important step in recent researches. Materials and Methods In the proposed method of this article, a hypothesis testing function is defined to separate biological particles from artifact and noise in captured v...

An imaging technique is introduced that is suitable for visualizing the mode shapes of vibrating structures in an educational setting. The method produces images similar to those obtained using electronic speckle pattern interferometry (ESPI), but it can be implemented for less than 1/10 the cost of a commercial ESPI system, and the apparatus is simple enough that it can be constructed by under...

For production of high quality PBX charges, it is essential to have low viscosity formulations available during the casting process. As generally known, for a certain filling grade, casting viscosity depends strongly on particle size distribution and on particle shape. We have shown in previous work, that a high tap density of the solid energetic material is one strong requirement to get low vi...

Recycling waste concrete has become a large problem in developing countries. The aim of this work is to provide guidance for screening particles and improving efficiency. First, the elastoplastic collision model established calculating coefficient restitution with different compressive strengths. Then, bar circular vibrating screen applied simulate process by using discrete element method (DEM)...

The low-cost cleaning and classification of granular agricultural products in a vibrating environment is possible via the mathematical modeling movement grain on surface screen. In this study, design analysis vibratory screen used for classifying peanuts has been realized. Therefore, firstly model process developed based carried out making translation surface. A 6- bar mechanism was selected as...

healthcare professionals usually should make complex decisions with far reaching consequences and associated risks in health care fields. as it was demonstrated in other industries, the ability to drill down into pertinent data to explore knowledge behind the data can greatly facilitate superior, informed decisions to ensue the facts. nature has always inspired researchers to develop models of ...

application of cogeneration systems based gas turbine for heat and power production is increasing. because of finite natural energy resources and increasing energy demand the cost effective design of energy systems is essential. cgam problem as a cogeneration system is considered here for analyzing. two new approaches are considered, first in thermodynamic model of gas turbine and cogeneration ...

Abstract This paper aims to review the impact of different factors influencing corrosion resistance electroless Ni-P based coatings. Emphasis has been given onto phosphorus content, incorporation alloying elements, addition particles and heat treatment which have discussed in detail critically reviewed. The effect corrosive media coating process parameters on are studied concisely. Furthermore,...
