Irregularity detection on low tension electric installations by neural network ensembles
2009 International Joint Conference on Neural Networks, 2009The volume of energy loss that Brazilian electric utilities have to deal with has been ever increasing. The electricity concessionaries are suffering significant and increasing loss in the last years, due to theft, measurement errors and many other kinds of irregularities. Therefore, there is a great concern from those companies to identify the profile

Transmission Error in Synchronous Belt With Resonance Under Installation Tension
Journal of Mechanical Design, 2011Synchronous belt drives generate resonance on the belt spans between the driving and driven pulleys when the transverse natural frequency of the belt, matches the meshing frequency of the belt tooth and the pulley tooth. The resonance of the belt spans affects the accuracy of rotation transmission.

A Method for Installing Zero-Tension Pan and Wick Lysimeters in Soil
Applied Engineering in Agriculture, 2011Zero-tension pan lysimeters and passive capillary fiberglass wick lysimeters are useful in determining water quality and volumetric aspects of subsurface water flow. A crucial aspect of installing pan and wick lysimeters beneath undisturbed soil is preventing cave-in of the tunnels in the soil that house the lysimeters.

The Study of High Strength Bolt Preload with Hydraulic Tensioner Installation
Advanced Materials Research, 2011Preloading the high strength bolt using hydraulic extension method is a fast and efficient method for bolt installation. Hydraulic bolt tension device can guarantee the initial tension of bolt well. However, if the relation of initial tension and the final remaining preload of bolt cannot be determined, the preload on the bolts still cannot be ...

Surface tension: permeability, the body, and installation
2023Surface Tension – Permeability, the Body, and Installation, is comprised of a multimedia installation and an accompanying minor thesis. The concurrent points of departure for both are the body and the medium of installation itself, exploring their sympathies with the lens of permeability.

Optimization of Tension Level and Stinger Length for Offshore Pipe line Installation
Offshore Technology Conference, 1973ABSTRACT Offshore pipelines have been installed for a period of' some 10 to 20 years using a variety of methods. This paper presents a new analysis method for the optimization of certain operation parameters in laying continuous pipe under tension from a barge. This method of optimization is now being used by one of

Measurement of Individual Conductor Tension During Pipe-Type Cable Installation
IEEE Transactions on Power Apparatus and Systems, 1969Users of pipe cable have a strong economic incentive to space manholes as far apart as possible. To attain this objective, it is necessary to have accurate information on the stresses developed in each conductor during the pulling operation. This paper describes a novel method of measuring tension on each conductor at the pulling head and presents the ...

Offshore Technology Conference, 2018
Abstract Mooring tensioning systems for offshore floaters have evolved from rotary windlasses on ships into multiple options nowadays. These options include fixed or movable winches, either linear or rotary, driven by electric or hydraulic, and the most recent in-line tensioners which remove the on-vessel equipment.
