Sugarcane sector has a strong impact as a wealth generator for Brazil. Several authors discuss the importance of quantifying an agro-industrial system. This article aims to analyze the development of the Brazilian sugarcane sector over the past five years and to assess whether the method of mapping and quantification of agribusiness systems (GESis) is a useful tool for analyzing the economic de...

Sugarcane, Saccharum officinarum L., is one of the most economically important crop of Thailand. It is the main source of sucrose, and is used in sugar and alcohol production. Insect pest complex is the most important limiting factor in sugarcane production. Among the sugarcane insect pest complexes, the sugarcane moth borers complex is considered most important. Chilo infuscatellus Snellen, Ch...

This paper presents a low-profile, planar electromagnetic vibration energy harvester integrated with a Halbach array. Halbach array is a special arrangement of permanent magnets that doubles the magnetic field on one side of the array while cancelling the field to near zero on the other side. Using this arrangement can improve electromagnetic coupling in a limited space. The energy harvester ha...

This paper presents the electrical and thermal design of a thermoelectric energy harvester power system and its characterisation. The energy harvester is powered by a single Thermoelectric Generator (TEG) of 449 couples connected via a power conditioning circuit to an embedded processor. The aim of the work presented in this paper is to experimentally confirm the lowest ΔT measured across the T...

For light harvesters with a reaction center complex (LH1-RC complex) of three types, we propose an experiment to verify our analysis based upon antenna theories that automatically include the required structural information. Our analysis conforms to the current understanding of light-harvesting antennas in that we can explain known properties of these complexes. We provide an explanation for th...

Abstract Manual harvesting of sugarcane requires skilled labourers, as improper leads to a significant loss yield. Therefore, it is necessary move towards designing system capable on smallholdings, with high efficiency. This study aims determine some physico-mechanical properties stalks related harvester by making comprehensive analysis the compressing, bending, and shearing stalks. These were ...

Sugarcane (Saccharum spp. hybrids) has great potential as a major feedstock for biofuel production worldwide. It is considered among the best options for producing biofuels today due to an exceptional biomass production capacity, high carbohydrate (sugar + fiber) content, and a favorable energy input/output ratio. To maximize the conversion of sugarcane biomass into biofuels, it is imperative t...

Wearable medical and electronic devices demand a similarly wearable electrical power supply. Humanbased piezoelectric energy harvesters may be the solution, but the mismatch between the typical frequencies of human activities and the optimal operating frequencies of piezoelectric generators calls for the implementation of a frequency up-conversion technique. A rotary piezoelectric energy harves...

This paper presents a wireless sensor node (WSN) system where an electromagnetic (EM) energy harvester is utilized for charging its rechargeable batteries while the system is operational. The capability and the performance of an in-house low-frequency EM energy harvester for charging rechargeable NiMH batteries were experimentally verified in comparison to a regular battery charger. Furthermore...

In this work, we present an automatized, computationally efficient and stable compact modeling technique for a large-scale multiport model of MEMS based piezoelectric energy harvester. The method includes structure preserving model order reduction based on Krylov subspaces. We further demonstrate a cosimulation between the reduced harvester model and the power circuitry.
