this paper presents the results of the assembly process of a gasketed bolted flanged pipe joint for two different bolt tightening strategies, i.e. asme and industrial using torque control of preload method.  the final clamping force is achieved in four and five passes in asme and industrial strategy respectively. axial bolt stress variation, at the end of each pass, individual bolt bending beha...

Dynamic resource scaling enables provisioning extra resources during peak loads and saving energy by reclaiming those resources during off-peak times. Scaling the number of CPU cores is particularly valuable as it allows power savings during low-usage periods. Current systems perform scaling with a slow hotplug mechanism, which was primarily designed to remove or replace faulty cores. The high ...

Belian wood is very well known building construction material and been used since long time ago for both structural non-structural elements. Somehow belian buildings which have being exist many years or some functional changes in use need strengthening. One of the most popular strengthening method concrete jacketing as it practical mechanically increase capacity existing structures. This resear...

Extended Hollo-Bolts (EHBs) are blind bolts that have an extended bolt shank ending in anchor nut. When used with concrete-filled tubes, the extension and concrete serve to enhance significantly performance of both connection components: tension tube face bending. The enhancements a result confining concrete, preventing local buckling steel allowing achieve tensile strength equal standard bolt+...

The control difficulty of whole coal cavern groups is greatly increased due to the characteristics soft rock with low strength, large sections, and mutual influence crossed groups. section gas storage group taken as research background. In this paper, equivalent circle method used solve loose a rectangular roadway, numerical calculation obtain deformation stress distribution laws surrounding un...
