Many animals react to danger by producing chemical cues that can be smelled by others, which is called the smell of fear. Some bird species produce chemical compounds when threatened, such as nestlings of the Eurasian roller Coracias garrulus that vomit an odorous orange liquid when scared in their nests. Here, we experimentally explore the possibility that parents were informed about recent pr...

Improving the performance of idlers is paramount to conveyor system in various industries since belt conveyors can be many kilometers length and consequently there are a huge number rollers use. The key intention this work development light-weight composite idler roller. Critical design considerations strength-to-weight ratio performance. Most importantly, must reduce weight roller as compared ...

The multiobjective optimization of Slide-o-Cam is reported in this paper. Slide-o-Cam is a cam mechanism with multiple rollers mounted on a common translating follower. This transmission provides pure-rolling motion, thereby reducing the friction of rack-and-pinions and linear drives. A Pareto frontier is obtained by means of multiobjective optimization. This optimization is based on three obje...

Abstract Great efforts are currently being made to establish a solid base for the production of grain along with other agricultural products. One most important tasks in agriculture today is increase number cattle and poultry. In near future it necessary create specialized livestock complexes high-tech poultry farms each region. As result creation demand corn silage will increase. The efficienc...

ii iii Summary For the design of embedded systems the development of dynamic models of the controlled physical system becomes increasingly important. These models predict the behavior of the system in an early stage of the design process. It is important to use an efficient method for modeling that gives satisfactory results. In this project, a dynamic model has been made of the paper path in a...
