The use of equipment in the construction industry has expanded recent years due to equipment's ability complete most work items such as excavation work, casting, and more a relatively short period time. However, real challenge would be selecting appropriate accurately predicting productivity equipment. In projects, choice execute any is based mainly on expertise contractors without taking into ...

The paper discusses the enhancement of inherent safety by index methods. The aim is to study, how well the safety index methods can evaluate inherent safety compared to expert evaluations and Dow Fire and Explosion index values. Studies on four levels of scope from process concept selection to equipment design were done and correlations between indices and expert values calculated. It was found...

____________________________________________________________________ The calibration of accelerometers, angular rate sensors, and inertial measurement units (IMU) increases the accuracy of their measurements. For artillery rounds and most rockets, measurements are acquired while the body is spinning. By the comparison of the sensor output to known input, calibration is accomplished. Calibration...

Selection Algorithm and Generation Algorithm of elliptic curves have been the focus of research and hotspot of the Elliptic Curve Cryptosystem. This paper discusses a random elliptic curve realization method of Embedded Mobile Equipment, the SEA algorithm and its improved algorithm from Elliptic Curve's selection, Elliptic Curve's structure and Elliptic Curve's generation. Ensuring that the emb...

Computer-aided design of modern robotic manufacturing cells involves solution of a number of complicated optimization problems that are related to equipment selection, scheduling, routing and path planning. The paper deals with three of them: optimal selection of robotic tools, optimal clustering of welding dots among robots, and optimal layout design. A number of efficient genetic algorithms a...

the dogleg severity is one of the most important parameters in directional drilling. improvement of these indicators actually means choosing the best conditions for the directional drilling in order to reach the target point. selection of high levels of the dogleg severity actually means minimizing well trajectory, but on the other hand, increases fatigue in drill string, increases torque and d...

The use of wire-coils is especially relevant at low Reynolds numbers (below the critical number to turbulent flow in smooth tubes) according its inherent positive features such as advance transition onset and, if they present suitable geometric characteristics, establishment an extended transitional a interval [ReCL-ReCT], with predictable friction coefficient and Nusselt number. This paper pre...
