Two parts, each with two holes, are to be pinned together by some type of fastener. Nominally the holes on part 1 are to match the holes on part 2 and the fastener diameters should be smaller than the hole diameters. Due to variation in hole diameters, fastener diameters and hole center positions loose pinning of the two parts may no longer be possible. The problem considered here is to define ...

When a thin elastic sheet crumples, the elastic energy condenses into a network of folding lines and point vertices. These folds and vertices have elastic energy densities much greater than the surrounding areas, and most of the work required to crumple the sheet is consumed in breaking the folding lines or "ridges." To understand crumpling it is then necessary to understand the strength of the...

This case report describes the alternative use of an oral endotracheal tube fastener in a pediatric patient with junctional epidermolysis bullosa. The patient underwent dental treatment in the operating room under general anesthesia and had a medical history of junctional epidermolysis bullosa, prior secondary anemia, clubbed feet, and past methicillin-resistant Staphylococcus aureus infection ...

! ABSTRACT —;> Lightning protection of modern aerospace vehicles must prohibit sparking in critical fuel vapor areas. In the past, it has been particularly difficult to keep mechanical fasteners from sparking during a lightning event. Attempts to seal off the fasteners from the critical fuel vapor area by manual application of sealant material have proven to be ineffective due to gaps and voids...

Entrapment of prepuce in a zipper is a common cause of prepuceal injury in children. The reported interventions include dismantling the zipper with bone or wire cutters, to circumcision. A quick, simple and non-traumatic approach to the zipper manipulation is presented in which prepuce is instantly released by lateral compression of the zip fastener, using a pliers.

The embedment strength performance of the self-tapping screw (STS) connector, used as a cross-laminated timber fastener, was evaluated considering tree species’ density and load direction parameters. STS had diameter 8, 10, 12 mm. Considering characteristics STS, threaded area shank were compared. A larger resulted in higher yield all directions respective wood. effective can estimate more accu...

In this work, a novel high-speed railway fastener detector is introduced. This fully convolutional network, dubbed FasteNet, foregoes the notion of bounding boxes and performs detection directly on predicted saliency map. FasteNet uses transposed convolutions skips connections, effective receptive field network 1.5\(\times \) larger than average size fastener, enabling to make predictions with ...

Controlled compliance and accommodation matrix techniques are considered for robust insertion of threaded fasteners. Errors in translational positioning are shown to be easily corrected. Errors in the angle of tilt between the threaded parts are shown to be much more diicult to correct and constrain the region of convergence for simple linear techniques.
