Evaluation of Field Tests Performed on an Aluminum Deck Bridge
… County, VA. The topics researched from the load tests are the composite action amongst the deck and supporting members, the load distribution amongst supporting members, the dynamic load allowance for supporting members, and the developed deck stresses due to test truck loads. Evaluations of the …

Improving visual field tests for populations with advanced glaucoma and visual field loss in the periphery
The visual field can extend up to 100° in the temporal visual region; however, in patients with glaucoma and other diseases that affect peripheral vision, only the central 30° of the visual field is monitored regularly in clinical practice using static perimetry. These static tests are rapid and …

Upper extremity strength and power field tests as predictors of pole vault performance in female collegiate athletes
… if select upper-extremity strength and power field tests, and the test battery, predict pole vault performance in female pole vaulters. There is very little research on female pole vault athletes, specifically non-elite athletes. Field tests previously shown to be predictive of performance in …

High-performance and self-compacting concrete in house building. Field tests and theoretical studies of possibilities and difficulties
… is dominated by production studies performed in field with the aim of investigating the ‘real’ potential of SCC addressing technical/practical and economical issues. These case studies consist of observations and measurements of the consequences when normal concrete is replaced by SCC. The result …

Evaluation of corrosion behaviour of hot dip Zn and Zn-Al alloy coatings on steel wire using laboratory and field tests
The use of galvanised coatings on steel for structural ropes, bundles and wires has become standard practice as unprotected steel is prone to corrosion degradation. Galvanised coatings increase the service lifespan of steel by providing barrier and cathodic corrosion protection. Zinc (Zn) and …

Factors related to cycling performance
… The first goal was to determine if results from field tests (time-trials and a Conconi incremental test) are related to performance in mass-start long-distance bicycle races. The second goal was to investigate inter-relationships among field test variables. The testing variables measured were …

Determinação de propriedades dinâmicas do solo no campo para análise de fundações de máquinas rotativas
… mass-type vibrator was designed and constructed. Field tests on a block-type foundation, resting on residual soil, were carried out and allowed the determination of dynamic soil properties and an evaluation of the efficiency of the vibrator. A procedure for conducting vibration-type field tests …

Navigation Control for Autonomous Tractor Guidance
… was conducted with both computer simulation and field tests on an agricultural tractor platform equipped with RTK-GPS and FOG posture sensors. The field tests showed that the root mean squared (RMS) offset error was less than 0.05 m and the maximum offset error was less than 0.1 m for a straight …

Detection of subsurface anomalies in composite bridge decks using infrared thermography
… laboratory conditions. In addition, several field tests were conducted using infrared thermography on the composite decks of two bridges (Wickwire Run and Laurel Lick) located in West Virginia. The field tests were used to detect subsurface delaminations and study the effect of environmental …

A bathymetric sidescan sonar system
… over a 39 degree vertical sector is described. Field tests conducted at a dam site indicate that the completed system does not function as required. This is due to errors in the sonar depth measurement which are caused by reverberation resulting from the multiple scattering of sound from the dam …

DYNAMICS OF A SUBMERSIBLE MUSSEL RAFT
… tank testing, numerical modeling, and full-scale field tests. When submerged, the raft’s pontoons are flooded, and it is held vertically by lines attached to surface floats and horizontally by a spread mooring. This submerged configuration is used to reduce wave forcing and to avoid contact with …
