A nonlinear model predictive controller is designed for the strip temperature in a combined directand indirect-fired strip annealing furnace. Based on a tailored first-principles dynamical model and the estimated current system state, the receding horizon controller selects optimal trajectories for both the fuel supply and the strip velocity so that the strip temperature is controlled to its de...

We study the strip packing problem, in which a set of two-dimensional rectangular items has to be packed in a rectangular strip of fixed width and infinite height, with the aim of minimizing the height used. The problem is important because it models a large number of real-world applications, including cutting operations where stocks of materials such as paper or wood come in large rolls and ha...

Strip threadability is an ability to keep a strip flowing smoothly between interstands and run-out tables without severe longitudinal and lateral movements. The occurrence of a longitudinal movement is mainly related to looper–tension control performance, while a lateral movement is affected by steering control actions. Unstable threading may induce folding and pinching of a strip, thus resulti...

We described an assay for theophylline in serum in which the reagents for the substrate-labeled fluorescent immunoassay procedure are dry reagents in a paper matrix. This assay format is both rapid and convenient. In one such paper strip assay, the competing drug conjugate is present in the diluting buffer (dilution-into-conjugate strip assay); in another, all necessary assay reagents are conta...

this paper describes the design of a 2x2 micro strip patch antenna array in the frequency of 9.5ghz for radar applications, using substrate integrated waveguide, siw, for feeding network. the micro strip patches are aperture-coupled with the feeding network of siw. the feeding network consisting of a perpendicular coax-to-siw transition and two y-junction power dividers. the antenna is simulate...

results in total, 80 food samples suspected of seb contamination were assessed using the two methods. fifty-four samples were contaminated based on the pcr technique and twenty-six of those were confirmed using the strip assay. conclusions the sensitivity of the sandwich method was approximately 10 ng/ml and that of the competitive method was approximately 250 ng/ml. in the lfd, a highly specif...

Glucose oxidase (GOD) from Aspergillus niger and horseradish peroxidase (POD) were co-immobilized onto arylamine glass beads affixed on a plastic strip with a conjugation yield of 28.2 mg/g and 43% retention of their initial specific activity. The coimmobilized enzymes showed maximum activity at pH 7.5 when incubated at 37 degrees C for 15 min. A simple, specific and sensitive method for discre...

The size and nature of the zone of inhibition round a benzylpenicillin disc have been widely used as guides to the sensitivity or resistance of a strain of Staphylococcus aureus. However, the diameter of the zone ofinhibition depends on many factors, including inoculum size, depth of medium, and potency of the antibiotic test disc. Inoculum size, in particular, may be difficult to standardise w...
