In this paper, we established the exploitation of impulsive harvesting single autonomous population model by Logistic equation. By some special methods, we analysis the impulsive harvesting population equation and obtain existence, the explicit expression and global attractiveness of impulsive periodic solutions for constant yield harvest and proportional harvest. Then, we choose the maximum su...

The location and operation of harvest machinery, along with the design and construction of access roads, are important problems faced by forestry planners, making up about 55% of total production costs. One of the main challenges consists of finding a design that will minimize the cost of installation and operation of harvest machinery, road construction, and timber transport, while complying w...

A simulation model, which depicts the harvesting operation of biomass supply chain, is presented in this paper. ExtendSim8 simulation software was used for the development of the model. There are a number of sequential operations, i.e. mowing, drying, baling, picking-up, loading, and transporting, for harvesting biomass until the final product arrives at bio-energy generation plant. Different s...

Two vital challenges arise in the next generation 5G networks: scarcity of spectrum and the aspect of energy efficiency (EE). In this letter, we first formulate the prime issue, i.e., energy harvesting (EV) for 5G wireless networks, in which spectrum and energy resources are efficiently received and resourcefully managed. Thereafter, we introduce a medium access control (MAC) scheme for dual ti...

This paper research of productivity and work organization were investigated of a group made of five workers (two cutters, two tractor drivers and one cutter-inspector) and a team leader. The teamwas equipped with two tractors and three chain saws. The research was carried out in the area of management unit – Ju`na Krndija Kutjeva~ka, at an altitude ranging between 550 m and 750 m in a 55-year b...

Sugarcane-based ethanol in Colombia has a prospective opportunity to explore the production of ethanol from lignocellulosic biomass taking into account that a large amount of generated residues (between 50 and 100 t/ha) are left on the field after green harvesting. The use of sugarcane green harvesting residues for ethanol production could be considered as a feasible solution but it is facing h...
