An immunochromatographic strip was developed for the detection of the H9 subtype of avian influenza viruses (H9AIVs) in poultry, using two monoclonal antibodies (MAb), 4C4 for H9AIV hemagglutinin (HA) and 4D4 for nucleoprotein. The 4C4 MAb was labeled with colloidal gold as the detection reagent, and the 4D4 MAb was blotted on the test line while a goat anti-mouse antibody was used on the contr...

strip tearing during cold rolling process has always been considered among the main concerns for steel companies. several works have been done so far regarding the examination of the issue. in this paper, experimental data from cold rolling tandem mill is used for detecting strip tearing. sensors are placed across the cold rolling tandem mill. they receive information on parameters (such as ang...

The final hot strip profile is a superposition of the roll initial crown, the roll bending and flattening crown, the roll wearing crown and the roll thermal crown. In this research, linear regression models are proposed to predict the roll force, the roll wearing crown and the roll thermal crown using experimental data provided by Mobarake Steel Complex (MSC). The Euler-Bernoulli beam theory ba...

With the increasing pulse rates of airborne laser scanners point clouds become an interesting data source for mapping beyond the production of digital terrain models. Whereas height accuracy of point clouds is of prime importance for terrain models, mapping of buildings and other objects also requires an analysis of planimetric accuracy of point clouds. This paper presents a methodology to esti...

We consider the two-dimensional bin packing and strip packing problem, where a list of rectangles has to be packed into a minimal number of rectangular bins or a strip of minimal height, respectively. All packings have to be non-overlapping and orthogonal, i.e., axisparallel. Our algorithm for strip packing has an absolute approximation ratio of 1.9396 and is the first algorithm to break the ap...

Good algorithms exist for solving the 2D rectangular strip packing problem when the objective is to minimize the amount of wasted material. However, in some applications other criteria are also important. We describe new heuristics for strip packing that optimize not only for wastage, but also for the efficient use of the cutting equipment, by minimizing the number of independent cuts required ...

Plants achieve mineral ion homeostasis by means of a hydrophobic barrier on endodermal cells called the Casparian strip, which restricts lateral diffusion of ions between the root vascular bundles and the soil. We identified a family of sulfated peptides required for contiguous Casparian strip formation in Arabidopsis roots. These peptide hormones, which we named Casparian strip integrity facto...
