Modification of the rotary machining process to improve surface form
Planing and moulding operations carried out within the woodworking industry make
extensive use of rotary machining. Cutter-marks are produced on the timber surface
which are generally accepted as unavoidable. More noticeable surface defects may be
produced by such factors as cutter-head imbalance, and until recently most research has
concentrated on removing these defects. When a high quality finish is required, a further
machining operation, such as sanding, is often required to remove cutter-marks. What is
required, is a modified machining process which combines a surface closer to the ideal
fixed knife finish, whilst retaining the flexibility, practicality and cost effectiveness of
rotary machining. [Continues.
Automatic gravure print feature determination at production speeds
This paper describes the development of a non-contact system for measuring the colour of printed material at web speeds, in addition to gravure-printed dot feature recognition. The system proposed uses a non-contact spectrophotometer based on a holographic grating, in conjunction with a conventional monochrome area scan camera, from which colour spectral data are extracted, while a xenon flash is used to illuminate colour samples. Dot features are captured by a magnification lens, in conjunction with a progressive scan camera. Software and hardware details of the system are given, together with the underlying mathematics for colour space conversion and measurement. Conversion equations from X, Y, Z chromaticity coordinates to the RGB system are presented, and also equations to convert from the L*a*b* colour space to X, Y, Z chromaticity coordinates. Experimental results are presented whereby the non-contact spectral system is shown to perform to a colour tolerance exceeding that of conventional colour video systems, and where performance of the dot feature system is comparable with traditional static examination methods using a microscope
Machine vision in conjunction with a knowledge-based system for semi-automatic control of a gravure printing process
This paper describes the work carried out to produce an automated print inspection system, which was developed on a gravure printing press within the wall-covering printing industry. The project aim was to produce a system that could continuously monitor the gravure printing process, by examining printed material using machine vision, and then by using a fuzzy knowledgebased system to interpret the machine vision system output and to make recommendations to an operator as to how to correct the process with simple text-based suggestions, avoiding printing of scrap material

Paralogue protein groups in Fusarium venenatum. Some groups show adjacent (neighbour) groupings representing recent duplications, whilst others represent near neighbours (< 40 genes) and others more distant duplications (> 100 genes). (XLS 38 kb

Co-inoculation of F. venenatum with plant-pathogenic Fusaria in vitro and in vivo. (A) Carrot agar plate inoculated with agar plugs of strains Fv A3/5, two isolates of Fg (PH1 and 602), and Fc UK99. A barrage line between strains is visible at day 6. (B) F. culmorum and F. venenatum spores where mixed in equal amounts and co-inoculated into two spikelets at anthesis. As a control, water was inoculated (C) F. venenatum spores were sprayed onto wheat heads at the booting stage to potentially prime plant defence responses, followed by point-inoculation with F. culmorum spores of two heads per spike" should be "two spikelets per head at anthesis. (D) Wheat plants were treated as in C. Just after inoculaton with F. culmorum, wheat heads were sprayed once more with F. venenatum spores until run-off. Error bars show standard deviation, n = 6.
