Ergonomic handling of electric pen drill for passing K-wires

Automated Core Sample Handling for Future Mars Drill Missions

Signs of microbial life on Mars, if they exist, will probably exist underground. This paper describes a robotics system for handling and sub-sampling cores taken from a robotic drill. The system prepares samples for analysis and life detection experiments. This system has been integrated with a drill and other instruments and tested in the field. This paper presents a description of the system ...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

A telegrapher equation for electric - telemetering in drill strings

A reliable method of transmitting downhole information to the surface while drilling is essential to improve drilling applications. We have designed a numerical algorithm for simulation of electric-signal transmission through the drill string, based on the telegrapher equation (a circuit model). The drill string is then represented by a transmission line with varying geometrical and electromagn...

Decomposition of Two Types of Electric Wires

12 Combustion runs at 700 oC in a horizontal laboratory furnace were carried out on two 13 different electric wires (PVC and halogen-free wire). Tests were performed in the 14 presence and in the absence of the metal conductor of the wires. The analyses of the 15 polycyclic aromatic hydrocarbons (PAHs), chlorobenzenes (CBzs), chlorophenols 16 (CPhs), monoto octa-chlorodibenzo-p-dioxin and diben...
