Fatalities due to tractor overturns have long plagued the U.S. farm community. Constituting 20% of agricultural fatalities, tractor overturns contribute significantly to high rates of fatal injuries. In the past, many efforts have been directed toward reducing tractor overturns, with one successful US-based program offering rebates to farmers who retrofit their tractors with rollover protective...

The force measuring device is designed to the study of the relationship between vibration amplitude, frequency, speed and traction resistance of the tractor If the design of the force measuring device which consists of a force measuring frame and three octagonal ring transducers is successful, the goal of real-time monitoring of the traction resistance in the process of vibrating sub soil may b...

one the challenging in hardware performance is to designing a high speed calculating unit. the higher of calculations speeds in a computer system  will be pointed out in terms of performance. as a result, designing a high speed calculating unit is of utmost importance. in this paper, we start design whit this knowledge that one multiplier made of several adder and one divider made of several su...

Simultaneous (or concurrent) Engineering, is a concept which should be normal nowadays. Then, without early and simultaneous involvement of all departments, specialists, special suppliers and potential external consultants, you are no longer able to develop these ever more complex agricultural machines. In that case „simultaneous“ means to be faster on the market, because all manufacturers can ...

BACKGROUND Agricultural tractor overturns without rollover protective structures are the leading cause of farm fatalities in the United States. To our knowledge, no studies have incorporated the spatial scan statistic in identifying high-risk areas for tractor overturns. The aim of this study was to determine whether tractor overturns cluster in certain parts of Kentucky and identify factors as...

Previous studies have reported that tractors are responsible for high proportions of fatal and nonfatal agricultural injuries. However, many common and preventable risk factors, conditions, and associated costs related to tractor-related injuries have not been investigated. This case-based study used workers' compensation data to investigate tractor-related injuries. The objectives of this stud...

CR invariant differential operators on densities with leading part a power of the sub-Laplacian are derived. One family of such operators is constructed from the " conformally invariant powers of the Laplacian " via the Fefferman metric; the powers which arise for these operators are bounded in terms of the dimension. A second family is derived from a CR tractor calculus which is developed here...

Programmable reversible logic circuit is design style for nanotechnology and quantum computing with minimum heat generation, quantum cost and garbage output. Late advances in reversible rationale utilizing and quantum PC calculations consider enhanced PC engineering and math rationale unit plans. In this paper, we survey the N-bit reversible logic adder and sub tractors are used with minimal de...

Farmers experience whole-body vibrations when they drive tractors. Among the various factors that influence the vibrations to which the driver is exposed are terrain roughness, tractor speed, tire type and pressure, rear axle width, and tractor seat height above the ground. In this paper the influence of tractor seat height above the ground on the lateral vibrations to which the tractor driver ...

OBJECTIVE The purpose of this systematic review was to evaluate the effectiveness of roll-over protection structures (ROPS) as an engineering control for prevention of fatalities from farm tractor roll-overs. METHODS Using a systematic approach to literature searching, relevant studies from peer-reviewed journals, technical and government reports, and unpublished reports were retrieved. Studi...
