Throughout the spring 2013 semester I continued to work on the frictional model for a rotating lifter system. The previous frictional model assumed friction to be a constant, which only showed to be valid for sufficiently small values of . Now it has been determined that friction is proportional to the velocity, which is valid through all angular displacements. Allowing the lifters to move thro...

The technology of the divider and lifter mechanisms a garlic harvester using depth limit, straw divide, lift modes was studied in Lanling County, Shandong Province, China, according to characteristics high hardness, good uprightness narrow row spacing planting. A test prototype designed manufactured. Single-factor experiments orthogonal regression were carried out experimental factors working s...

The warehousing system is a means of supporting production activities and industrial operations that function to store goods be distributed, which are still using manual must adapt technological developments. problem often arises in the done manually flow into warehouse not well organized, this makes it difficult when about removed, so requires longer search time. Previous research has shown ac...

The performance of existing speech recognition systems degrades rapidly in the presence of background noise when training and testing cannot be done under the same ambient conditions. The aim of this paper is to report the application of several robust techniques on a system based on the HMM (Hidden Markov Models) and VQ (Vector Quantization) approaches for speech recognition in noisy car envir...

A deeper understanding of the milling operation of ball mills helps mineral processing engineers to control and optimize them, and therefore, reduce their consuming power. In this work, the milling operation of ball mills is investigated using two methods, i.e. DEM and combined DEM-SPH. First, a pilot scale ball mill with no lifter is simulated by both methods. Then another pilot scale ball mil...

this paper focuses upon the development of an efficient method for conceptual design optimization of a satellite. there are many option for a satellite subsystems that could be choice, as acceptable solution to implement of a space system mission. every option should be assessment based on the different criteria such as cost, mass, reliability and technology contraint (complexity). in this rese...
