abstract- noise is considered as one of the most debilitating conditions in farming operations. in this study, a number of factors affecting the noise generated by sampo 3065 combine harvesters were evaluated. factors were engine speed and gear ratio for combines with and without original cabins. a factorial experiment arranged as a completely randomized design with four replicates was used. re...

Abstract A desk top analysis was conducted to assess the feasibility and economics of introducing a fully mechanised combine harvesting system on several farms of a miller cum planter estate located in the KwaZulu Natal Midlands of South Africa. Machinery and equipment costing exercises based on row length, haul-out distance and harvester forward speeds were investigated. The outcome of the stu...

rice is one of the most important staple cereals‏ ‏in iran and has a main role in providing ‎the food ‎security. harvesting by hand postpone the rice harvesting stage, and facing late season ‎rainfall, and increase of yield losses during harvesting. to determine the most suitable ‎harvesting method in gilan, three different harvesting methods (by hand, harvester and ‎combine) were considered as...

This paper introduces the basics of energy harvesters and demonstrates two specific vibratory-type energy harvesters developed at the University of Hyogo. The fabrication and evaluation results of the vibratory-type energy harvesters, which employ electrostatic and electromagnetic mechanisms, are described. The aim of developing these devices is to realize a power source for an autonomous human...

This paper presents the design, fabrication, and testing of a harvester that extracts energy from moth-body vibrations during flight. The target moth is manduca sexta, which has a payload capacity near 1 g, and a dorsal payload volume approximately 8 mm wide and 15 mm tall. Operating within these constraints, the energy harvester is designed to deliver 1 mW of electrical power at 1 VDC for gene...

Corn stover has great potential as a biomass feedstock, but harvest and storage of this material is challenged by weather conditions at harvest; material moisture; and equipment shortcomings. Field drying characteristics, harvest efficiency and rate, product bulk density, and storage characteristics were quantified for stover harvested and stored in wet or dry form. Only in one case did stover ...

Because of their constant renewal, it is necessary to acquire fresh named entities (NEs) from recent text sources. We present a tool for the acquisition and the typing of NEs from the Web that associates a harvester and three parallel shallow parsers dedicated to specific structures (lists, enumerations, and anchors). The parsers combine lexical indices such as discourse markers with formatting...

This article presents a simplified model for studying the main parameters for magnetically plucking piezoelectric beams in energy harvesting devices. The advantage of magnetic plucking is that there is no impact on the brittle piezo material. However, achieving a good release of the piezo beam is more difficult than with fingers or plectra. The influence of different magnet arrangements, the ga...

We present an electromagnetic linear vibration energy harvester with an array of rectangular permanent magnets as a springless proof mass. Instead of supporting the magnet assembly with spring element, ferrofluid has been used as a lubricating material. When external vibration is applied laterally to the harvester, magnet assembly slides back and forth on the channel with reduced friction and w...
