Detecting and escaping infinite loops using Bolt
In this thesis we present Bolt, a novel system for escaping infinite loops. If a user suspects that an executing program is stuck in an infinite loop, the user can use the Bolt user interface, which attaches to the running process and determines if the program is executing in an infinite loop. If …

Effect of Cracking on Lag Bolt Performance
This dissertation presents the results of testing to determine the load-slip characteristics of single-shear single lag screw connections subjected to monotonic lateral loading parallel to grain. Of particular importance was the comparison of experimental capacity and 5% offset yield load …

Sensitivity Analysis of Self-Loosening Behavior forMesoscale Bolt Assemblies Under Cyclic Lateral Loading
… the understanding of self-loosening in mesoscale bolt assemblies, specifically those with characteristic dimensions ranging from 100 to 3,000 micrometers. These bolts pose unique design challenges due to the small difference between their nominal dimensions and manufacturing tolerances. This work …

Development and Validation of a Twelve Bolt Extended Stiffened End-Plate Moment Connection
… seismic applications in AISC 358-10. The eight bolt extended stiffened connection is the strongest of the three configurations, but it can only develop approximately 30 percent of currently available hot-rolled beam sections. The strength of this configuration is limited by bolt strength. There …

Investigation of Single and Two Bolt Connections Perpendicular to Grain in Laminated Veneer Lumber
Bolted connection with perpendicular to grain loading has been considered as a high priority research area by Smith and Foliente (2002), for the advancement of the load resistance factor design (LRFD) of connections. The results obtained from the experimental testing of this research will provide …

A New Rock Bolt Design Criterion and Knowlwdge-based Expert System for Stratified Roof
Since its development in the 1920s, bolting has become the most dominant support method in underground construction. However, because of the geological environment, the design process for roof bolt systems is an art rather than a science. To quantify the selection of bolting systems a MSBT (minimum …

The Effects of Bolt Spacing on the Performance of Single-Shear Timber Connections Under Reverse-Cyclic Loading
… others contributed to a better understanding of bolted connection behavior under reverse-cyclic loading. However, some questions remained. Billings was unable to consistently produce yield modes III and IV, meaning that her suggested bolt spacing of seven times the bolt diameter (7D) could not be …

The Impact of the Gig Economy on the Well-being of Independent Contractors. A Case Study of Uber, Bolt and Gokada
The gig economy is a rising global phenomenon in which gig workers provide “alternative work arrangements” for short-term contracts; also known as gigs, primarily agreed upon via digital platforms for various services such as food delivery or transportation. Work in the gig economy is typically …

Analytical and experimental investigation of a flush moment end-plate connection with six bolts at the tension flange
… investigation was conducted to study the six bolt flush moment end-plate connection configuration which is used in steel frame construction. The limit states of plate yielding and bolt fracture were analyzed using yield-line theory to predict endplate thicknesses and a split-tee analogy to …
