A Flock-Sprayed Test-Object Holder

A Test Lens Rack Holder.

A Holder Needle.

THE finest movements of surgery are made with the fingers and thumb, not with the wrist and hand as a whole. In the usual method of suturing, the needle is grasped by the needle-holder which is held more or less in the palm of the hand. The fine, sharp needles of ophthalmic surgery, such as those made by Grieshaber, inevitably become dulled as they are grasped by the metal blades of the needle-...

A New Semifield Flock

Let K be a quadratic cone of PG(3, q) with vertex v. A flock F of K is a partition of K"[v] into q conics. If all planes containing the elements of the flock F share a common line, then F is called linear. Given a flock F there is a standard construction of a generalized quadrangle Q(F) associated with F ([19]), which is classical if and only if F is a linear flock. Article ID jcta.1998.2933, a...

Moving Object Detection Using Scanning Camera on a High-Precision Intelligent Holder

During the process of moving object detection in an intelligent visual surveillance system, a scenario with complex background is sure to appear. The traditional methods, such as "frame difference" and "optical flow", may not able to deal with the problem very well. In such scenarios, we use a modified algorithm to do the background modeling work. In this paper, we use edge detection to get an ...

Rethinking Holder

suggests are either slight or problematical themselves. But given that the profession still refuses to listen, the long, sad story of the scholarly tradition in English metrics cannot be told too often. Both experienced prosodists and those who are only occasional visitors to this field will find RM a useful and enjoyable guide to what Holder calls ’the muddled kingdom of meter’ (Chapter 1), ’t...
