It records one or more variables with respect to time. It is a X-t recorder. A strip chart recorder consists of: 1. A long roll of graph paper moving vertically. 2. A system for driving a paper at some selected speed. A speed selector switch is generally provided. Chart speed of 1-100 m/s are usually used. 3. A stylus driving system which moves the stylus in a near exact replica or analog of th...

We define a new class of ordered sets, called free triangle orders. These are ordered sets represented by a left-to-right ordering on geometric objects contained in a horizontal strip in the plane. The objects are called “free triangles,” and have one vertex on each of the two boundaries of the strip and one vertex in its interior. These ordered sets generalize the classes of trapezoid and tria...

Abstract We prove a Nekhoroshev type theorem for the nonlinear Schrödinger equation iut = −∆u+ V ⋆ u+ ∂ūg(u, ū) , x ∈ T, where V is a typical smooth potential and g is analytic in both variables. More precisely we prove that if the initial datum is analytic in a strip of width ρ > 0 with a bound on this strip equals to ε then, if ε is small enough, the solution of the nonlinear Schrödinger equa...

In this paper, an active vibration control of the translating steel strip in the zinc galvanizing line is investigated. The unwanted vibrations of the strip deteriorate the uniformity of the deposited mass on the surfaces of the steel strip and the consumption of zinc. The translating steel strip is modelled as a moving belt equation by using Hamilton’s principle for the systems with changing m...

A reusable enzyme strip for the determination of cholesterol was prepared by co-immobilizing cholesterol esterase (CEase), cholesterol oxidase (COD) and peroxidase (POD) onto alkylamine glass beads affixed on a plastic strip by a nonreactive fixative. The co-immobilized enzymes retained 71.42% of initial activity of free enzymes with a conjugation yield of 11.0 mg g beads and showed optimum act...

Three dimensional curls (‘‘hemi-helices’’) consisting of multiple, periodic and alternating helical sections of opposite chiralities, separated by perversions, are one of a variety of complex shapes that can be produced by a simple generic process consisting of pre-straining one elastomeric strip, joining it side-by-side to another and then releasing the bi-strip. The initial wavelength of the ...

Micro strip transmission lines are widely used, and for good reason. They are broadband in Trea hertz frequency. They provide circuits that are compact and light in weight. They are generally economical to produce since they are readily adaptable to hybrid and monolithic integrated circuit (IC) fabrication technologies at Tera Hertz frequencies. To better appreciate printed transmission lines a...

The finishing train of a hot strip mill has been modelled by using a constant volume element model. The accuracy of the model has been increased by using an Artificial Neural Network (ANN). A non-linear Rank Based Genetic Algorithm has been developed for the optimization of the work roll profiles in the finishing stands of the simulated hot strip mill. It has been compared with eight other expe...

We study strip packing, which is one of the most classical two-dimensional packing problems: given a collection of rectangles, the problem is to find a feasible orthogonal packing without rotations into a strip of width 1 and minimum height. In this paper we present an approximation algorithm for the strip packing problem with absolute approximation ratio of 5/3 + ε for any ε > 0. This result s...

We evaluated the MIC Strip Isavuconazole test against EUCAST E.Def 9.3 by using 40 wild-type and 39 CYP51A mutant Aspergillus fumigatus strains. The strip full inhibition endpoint (FIE) and 80% growth inhibition endpoint were determined by two independent readers, reader 1 (R1) and R2. The essential (within ±0, ±1, and ±2 twofold dilutions) and categorical agreements were best with the FIE (for...
