The development of communication in a population of agents is viewed as the behavior of a dynamical system. A deterministic communication system is shown, both experimentally and theoretically, to have point attractors that correspond to perfect communication. However, the determinism required for the presence of point at-tractors impedes the development of communication. A corresponding attrac...

ABSTRACT: In a tractor, the transmission system transmits power generated in engine to driving wheels, hydraulic systems, and take-off (PTO). There are several types of systems available Brazilian market ranging from simplest most advanced. Therefore, objective this study was verify different present 228 models agricultural tractors produced marketed Brazil during 2019. The tractor were grouped...

Mechanisation has made a comeback to agricultural policy in Africa, encouraging scholars revisit seminal literature on induced innovation. Recent studies emphasise the role for markets addressing Africa’s mechanisation gaps and warn about past government failures be avoided. The trust ability of offer optimal solutions is debatable. Markets are shaped, as states are, by interests their most pow...

Farm tractor skidding is one of the common methods of timber extraction in Turkey. However, the absence of an optimal skidding plan covering the entire production area can result in time loss and negative environmental impacts. In this study, the timber extraction by farm tractors was analyzed, and a new skid trail pattern design was developed using Linear Programming (LP) and Geographical Info...

The high number of accidents due to rollovers of agricultural machines has increased the interest of researchers and organizations for standardization in this field. In the 1960s, standards to test rollover protective structures (ROPS) for tractors were designed and approved. Similar standards were introduced in the 1990s for earth-moving machinery, but ROPS standards were not defined for self-...

This experiment tests the ability to provide Real Time Kinematic Global Positioning System corrections via a real time network (RTK GPSRTN) by utilizing a satellite Internet connections in the field to multiple tractors for precision agriculture. Precision agriculture technology improves sustainable production by providing more farmers with the ability to obtain highly accurate machine control ...

In this paper we look at the longer term impact of double cycling on port operations including crane, vessel, and berth productivity. Double cycling is a technique by which empty crane moves are converted into productive ones. We use a double cycling sequence that is operationally convenient, easy to model, and nearly optimum. We compare the performance of this sequence to those determined by a...

Hearing injury due to exposure to excessive noise during common farming activities is a significant problem for farmers. The aim of this study was to investigate factors that affect the level of risk to hearing caused by common farming activities. Noise levels on farms were measured across a range of activities and producer groups, and situational factors that effect noise levels were also inve...
