Fibring the complement of the Fenn-Rolfsen link
No full textIn this note it is shown that the complement of the singular linked spheres in four dimensions defined by Fenn and Rolfsen can be fibred by tori. Also a symmetry between the two componente is revealed which shows that the image provides an example of a Spanier-Whitehead duality. This provides an immediate proof that the α-invariant is non zero

Obituary for Earl Clement Davis, Unitarian Yearbook
No full textObituary for Earl Davis written in the annual Unitarian Yearbook published by the American Unitarian Association. These yearbooks often contained obituaries (referred to as a \u27Necrology\u27) for recently deceased ministers and leaders.
The author, Dan Huntington Fenn, was a Unitarian minister whose father, William Wallace Fenn, also a Uniatrian minister, once served as Dean of the Harvard Divinity School.https://commons.clarku.edu/funeral/1001/thumbnail.jp

Real time defect detection in welds by ultrasonic means
No full textThis thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.A computer controlled weld quality assurance system has been developed to detect weld defects ultrasonically whilst welding is in progress. This system, including a flash analogue to digital converter and built-in memories to store sampled data, a peak characters extractor and a welding process controller, enabled welding processes to be controlled automatically and welding defects to be detected concurrently with welding. In this way, the weld quality could be satisfactorily assured if no defect was detected and the welding cost was minimised either through avoiding similar defects to occur or by stopping the welding process if repair was necessary. This work demonstrated that the high temperature field around the weld pool was the major source of difficulties and unreliabilities in defect detection during welding and, had to be taken into account in welding control by ultrasonic means. The high temperatures not only influence ultrasonic characteristic parameters which are the defect judgement and assessment criterion, but also introduce noise into signals. The signal averaging technique and statistical analysis based on B-scan data have proved their feasibility to increase 'signal to noise ratio' effectively and to judge or assess weld defects. The hardware and the software for the system is explained in this work. By using this system, real-time 'A-scan' signals on screen display, and, A-scan, B-scan or three dimensional results can be printed on paper, or stored on disks, and, as a result, weld quality could be fully computerized.Sino-British Friendship Scholarship Schem
