Ergonomic Field Assessment of Bucking Bars during Riveting Tasks
Riveting tasks in aircraft manufacturing results in exposure to vibration from both rivet guns and bucking bars. Long term exposure to vibration has been associated with symptoms of vibration white finger and musculoskeletal disorders. Four different bucking bars of the same shape but different material and mass characteristics (90% tungsten, >90% tungsten, cold rolled and stainless steel) were...
متن کاملPsychoanalytic process and interactive phenomena.
Psychoanalytic process is defined as the interaction between the psychoanalyst and the patient, primarily through the interplay of transference and resistance. Transference and resistance are understood as a unitary phenomenon that can be expressed either as an intrapsychic potential or as an interpersonal relationship. One of the aims of psychoanalytic technique is to encourage, through interp...
متن کاملEfect of Variations of Riveting Process on the Quality of Riveted Joints
This thesis presents a study of the effect of controllable riveting parameters, mainly squeeze force, rivet length, rivet diameter tolerance, hole countersunk depth and hole diameter tolerance, on the quality of formed rivet. The quality of a formed rivet is determined by the geometry of its head formation and the extent to which the hole is filled. The study determines maximum allowable tolera...
متن کاملRiveting Hammer Vibration and Nerve Damage
Hand Arm Vibration Syndrome (HAVS) is an occupational disease affecting 50% of riveting hammer operators after 10 years of work. Current international standards (ISO 5349) seeking to protect workers from occupational vibration are not effectively predicting HAVS onset. Scarce research has been done which investigates the long term effects of riveting hammer vibration exposure and nerve regenera...
متن کاملLocal/Global Phenomena in Geometrically Generated Graphs
In recent years, a wealth of random graph models have arisen to explain the power-law degree distribution observed in the Internet [1] and other complex networks (see, for example, [6] and [8]). While power-law behavior often drives these models, less is known about other very natural properties found in complex networks. One such notion is the local versus global structure of a network. In [12...
