A search for energy efficient, non-herbicide weed control methods led to development of a novel electrical weeding technology. This study focuses on efficiency and as elements system that would include machine vision robotics escape weeds in field crops. Two pulse generation systems, one single multiple, were developed evaluated at different delivered voltages energies. Greenhouse trials using ...

This chapter demonstrates the use of anti-windup compensation in the control loop of a micro-actuator which is nominally controlled by a linear, discrete robust controller. The micro-actuator is part of a hard disk drive dual-stage servo-control system for positioning of the read/write head. The actuator inputs are constrained to retain the micro-actuator’s displacement range of less than 0.4 μ...

Micro Electric Discharge Machining is a nontraditional machining process which can be used for drilling micro holes in high strength to weight ratio materials. This present research study deals with the single optimization of micro EDM process using Genetic Algorithm. Mathematical models using Response Surface Methodology (RSM) is used to correlate the response and the parameters. The desired r...

In this paper, a worm-like micro robot designed for inpipe application with intelligent active force control (AFC) capability is modelled and simulated. The motion of the micro robot is based on an impact drive mechanism (IDM) that is actuated using piezoelectric device. The trajectory tracking performance of the modelled micro robot is initially experimented via a conventional proportionalinte...

Prominent worldwide environmental problems makes the development of new energy distributed generation technology has been developed. Direct access to the low-voltage distributed power distribution network makes the system affected to some degree, in the form of micro-grid integration of distributed power is a good solution, and the presence of a large number of micro-grid inverter, micro-networ...

background and aims. promoting remineralization is the ultimate goal of clinical prevention of caries lesion. the present in vitro study aimed to investigate the effect of grape seed extract (gse) on artificial enamel caries in primary human teeth. materials and methods. seventeen human sound primary incisors were sectioned mesiodistally. the tooth slices were placed in a demineralizing solutio...

Introduction: In the present study, we assessed the effects of β-carotene on Titanium oxide Nanoparticle (TNP) induced mouse Spermatozoon Stem Cells (SSCs) apoptosis, at molecular level.  Methods: After isolation from cryptorchid mouse testis and characterization, spermatogonial stem cells were divided into four groups. In the control group, spermatogonial cells were cultured in &alp...

We demonstrated micro counter-current flow in a glass microchip utilizing surface modification patterning method to control surface tension. In order to visualize the micro counter-current flow, fluorescent microparticle dispersion solutions were observed by fluorescence microscopy. When the flow volume ratio of water and organic solution was changed, the switching point of flow direction was o...
