Around the globe, various types of forest machinery are employed to conduct fully mechanized ground-based timber harvesting. In Pacific Northwest, whole-tree harvesting method remains dominant. While machine-integrated sensors provide accurate productivity information in cut-to-length method, is more complicated determine This literature review compiles and analyses existing evidence on studies...

The rapid development of peanut mechanization has increased the amount dust expelled from mechanized operations, which degrades air quality and endangers health agricultural workers. Therefore, purpose this study is to figure out characteristics emission harvesting. To end, particulate matters diameters ? 2.5 ?m ?10 total suspended particles were sampled in real time during harvesting Henan Pro...

In Asia, decreasing farmer and labor populations due to various factors is a serious problem that leads to increases in labor costs, higher harvesting input energy consumption and less resource utilization. To solve these problems, researchers are engaged in providing long term and low-tech alternatives in terms of mechanization and automation of agriculture by way of efficient, low cost and ea...

A human operator assembles components using his skill and judgement which is difficult to incorporate in a mechanized device. Though the mechanized system will offer higher speed and reliability, but its inherent inaccuracies will limit the success in assembling. Thus, it is essential that these inaccuracies are determined to establish its ‘Process capability’ , and also provide information for...

Plantation forestry has a long history in Europe and still supports local industry, generating employment, improving environmental quality, mitigating climate change. As part of these plantations, medium-rotation poplars (5–8 years) provide good quality logs for fiber production, the branches tops can be converted into green energy. Finding cost-effective harvesting system this plantation is ch...

Energy harvesting, which offers a never-ending energy supply, has emerged as a prominent technology to prolong the lifetime and reduce costs for the battery-powered wireless sensor networks. However, how to improve the energy efficiency while guaranteeing the quality of service (QoS) for energy harvesting based wireless sensor networks is still an open problem. In this paper, we develop statist...

as a promising approach to enable self-sufficient and self-sustaining operation for devices in energy-constrained networks by scavenging energy from the ambient environment to power up devices. In particular, for wireless sensor networks, if the sensors, which spread throughout homes or factories, in buildings or even outdoors, are powered by energy harvesting, there are no batteries to replace...

Economic incentives to harvest a species usually diminish as its abundance declines, because harvest costs increase. This prevents harvesting to extinction. A known exception can occur if consumer demand causes a declining species' harvest price to rise faster than costs. This threat may affect rare and valuable species, such as large land mammals, sturgeons, and bluefin tunas. We analyze a sim...

In the pineapple sector of Benin, poor fruit quality prevents pineapple producers to enter the European market. We investigated effects of common cultural practices, flowering and maturity synchronisation, (1) to quantify the trade-offs of flowering and maturity synchronisation for pineapple quality and the proportion of fruits exportable to European markets, and (2) to determine the effect of ...
