Abstract:
The aim of the study was to determine the unit costs of mechanized timber harvesting in pine stands where early thinning was being performed, and to determine the relationship between the cost level and the volume of harvested trees, the harvester model and field conditions. Analysis focused on timber harvesting with the use of small- and mid-sized harvesters. The tested harvesters were specialized forestry machines (Vimek, Sampo, Profi-Pro, Ponsse) and a construction machine (Fao-Far). Terrain accessibility variants were distinguished in relation to furrows between which trees had been plante

Abstract:
The spindle picker and brush-roll stripper are the two machines used to harvest cotton produced in the U.S. Adoption of each harvester type is dictated by regional differences in production environment, production practices, cultivar, and yield. The spindle picker is a selective-type harvester that harvests seed cotton only from well-opened bolls, collecting a minimal amount of undesirable foreign material with the seed cotton. The brush-roll stripper utilizes a nonselective harvesting mechanism to indiscriminately remove mature seed cotton, immature bolls, sticks, leaves, and any other vegeta

Energy harvesting from ambient vibration has become an attractive topic in the recent years. Initial studies aimed to maximise the performance of small linear device for different excitation scenarios. These devices were assumed to be located in hostile and inaccessible environments and be able to provide energy for low powered sensors. Due to the limited size of the energy harvesters, however, the amount of power produced was small. More recently, many researchers have considered using nonlinear stiffness to improve the performance of these devices. This thesis, however, focuses on the use of

Abstract:
It has recently been shown that negligible linear stiffness or very small negative stiffness may be the most beneficial stiffness nonlinearities for vibrational energy harvesters due to the broadband, amplified responses which result from such designs. These stiffness characteristics are often achieved by providing axial compression along the length of a harvester beam. Axial compressive forces induced using magnetic or electrostatic effects are often easily tuned; however, electrostatic energy harvesters are practically limited to microscale realizations and magnets are not amenable in a vari

Abstract:
The specific working conditions of piezoelectric harvesters for scooter tires are analyzed. Calculated and experimental results show that the excitation of the harvester can be considered a series of separated impulses. Harvester response to an ideal impulse is analyzed with a single-mode model. An optimal ratio between impulse duration and natural period of the harvester that maximizes harvester excitation is found. A numerical finite element (FE) model of a bimorph cantilever harvester is developed in COMSOL and validated by means of experimental tests. The validated FE model is used for sho

Abstract:
Energy from pavements can be harvested in multiple ways to produce clean energy. One of the techniques is electromagnetic energy harvesting, in which mechanical energy from vehicles is captured in the form of input displacement to produce electricity. In this study, a rack-and-pinion electromagnetic energy harvester proposed in the literature as a speed bump is optimized for highway-speed vehicles. A displacement transfer plate is also proposed, with a minimum depth of embedment in the pavement to carry input displacements from passing vehicles and excite the energy harvester. The energy harve

Abstract:
This module’s goal is to introduce and evaluate a variety of common strategies for harvesting wild populations. The module includes reasons for harvesting, theoretical foundations for maximum sustainable yield and harvest strategies, age- and sex-biased harvests, and effects of harvesting on target and non-target wildlife. The module contains two case studies and a spreadsheet-based exercise suitable for either demonstration or laboratory use. The module also contains references to supplementary material that is freely available on the web.
