Tension Control In Narrow Fabric Weaving
… All of these techniques require a degree of yarn tension control for a good quality fabric because advanced fibres are easily damaged by excessive yarn tension. The cause of the sensitivity of advanced fibres to tension is their low extension. Textile industry standard yarns have extensions of 5% …

Underslung Payload Tension Control from an Autonomous Unmanned Helicopter
A tension control algorithm for the deployment of a unmanned ground vehicle from an autonomous helicopter is designed and tested in this thesis. The physical hardware which the controller will run on is detailed. The plant model and underlying controllers are derived and modeled. The tension …

Flexural Resistance Factors for Partially Prestressed Members Using ASTM A 1035 Reinforcing Steel
… 318 for increasing the strain limit that defines tension-controlled members using high-strength steel. The codes state that a tension-controlled member is any member with strain in the extreme tensile steel greater than 0.005. This limit is independent of the steel type. NCHRP 12-77 and Mast et …

Vibration assisted filling of thin section castings
… in profile shapes and clarifying the dominant control parameters of the vibration in thin wall investment casting is key to producing sound casting (one free of misrun defects). It's also a central issue for study in this thesis. The filling capability in thin wall investment casting method was …

Effects of Head Size on the Performance of Twist-Off Bolts
… measuring and comparing the achieved relaxed pretension force in the bolt after tightening. It was found that twist-off bolts with head diameters less than an ASTM F436 washer had no trouble attaining their required minimum pretension force. Bolt head diameter and hole size were found to have no …

The process intensification of biological hydrogen production by Escherichia coli HD701
… novel use of gas blending for dissolved oxygen tension control. Gas blending was used in a bioreactor to track the changes observed during growth in the shake flask. This created a process that mirrored the shake flask in both growth and hydrogen production. The outcome was a dry cell weight of …

Nylon Tension PID Control During Raw Tire Assembly
… purpose of this study is to evaluate several control methods to see which one has the best control of nylon tension during raw tire assembly. After nylon application step of the tire building process, the shape of the tire will undergo inflation that causes the nylon layers to expand and …
