Looper and tension control is important in hot strip mills because it affects the strip quality as well as strip threading. Moreover, the most difficult challange in the controller design and control performance comes from the interaction between looper angle and strip tension. Disturbances from several sources also cause a deterioration in control performance, and thus they should be rejected ...

We investigate the Within-Strip Discrete Unit Disk Cover problem (WSDUDC), where one wishes to find a minimal set of unit disks from an input set D so that a set of points P is covered. Furthermore, all points and disk centres are located in a strip of height h, defined by a pair of parallel lines. We give a general approximation algorithm which finds a 3d1/ √ 1− h2e-factor approximation to the...

A study of the materials properties of WC/SiC multilayer coatings is presented. We investigated the dependence of interface and surface roughness, intrinsic stress, microstructure, chemical composition, and stoichiometry as a function of multilayer period and in some cases compared these to W/SiC multilayer systems. The WC/SiC material pair forms multilayers with extremely smooth and sharp inte...

BACKGROUND Polypharmacy poses threats to patients' health. The Systematic Tool to Reduce Inappropriate Prescribing (STRIP) is a drug optimization process for conducting medication reviews in primary care. To effectively and efficiently incorporate this method into daily practice, the STRIP Assistant--a decision support system that aims to assist physicians with the pharmacotherapeutic analysis ...

use the ‘‘handle,’’ likened to an open scroll, to steady the patch strip as it is loaded with aqueous antigens and applied to the patient’s back. The cotton tipped applicator can then be gently reverse rolled out of position once the patch test strip is applied. This method allows for decreased handling of the adhesive surface, increased stability of the patch and ultimately much less risk of a...

The Rapignost-Amylase urinary test strip (Behringwerke Laboratories) provides an estimation of urine amylase which takes a few minutes and is easy to perform. During a period of 9 months, 84 patients had their urine tested with this strip by casualty officers in the Accident and Emergency Department of St George's Hospital, London. In addition, urine amylase, and plasma amylase and creatinine w...

Background/Aims: Beta (β)thalassaemia is a public health problem in Malaysia. The carrier rate is estimated to be 4.5% by micro-mapping studies particularly among Malays who comprise 53.5% of the population in Malaysia (1). The common diagnostic method in Malaysia for mutation detection is by amplification refractory mutation system (ARMS). It allows single mutation detection in each reaction b...

In the strip packing problem, a given set of axis-aligned rectangles must be packed into a fixed-width strip, and the goal is to minimize the height of the strip. In this paper, we examine a variant in which each rectangle may be cut vertically into multiple slices and the slices may be packed into the strip as individual pieces. Our results are: (1) analysis of the approximation ratio of sever...

The MSA Agent is the software developed to design rectangular and U slotted micro strip antenna. It is applied for the various applications such as satellite communications, UHF applications. Within the multimedia frequency range the developed software is tested and analyzed for various results. The software is developed using genetic algorithm. This provides extra flexibility and new capabilit...
