A new kind of double short strip and single-side micro strip type antenna architecture to develop a frequency reconfigurable annular slot antenna. The design and characterization of this "reconfigurable antenna (RA) annular slot" which was built on a microwave laminate TMM10i Rogers (permittivity=9. 8, loss tangent=0. 002), are presented in this paper. By increasing and decreasing the...

Submitted for the DFD15 Meeting of The American Physical Society Generalized “thick” strip modelling for vortex-induced vibration of long flexible cylinders1 YAN BAO, RAFAEL PALOCIOS, SPENCER SHERWIN, Imperial College London, NEKTAR++ COLLABORATION — We propose a generalized strip modelling method that is computationally efficient for the VIV prediction of long flexible cylinders in three-dimen...

The two-dimensional strip packing is a special case of “Cutting and Packing” problems that arises in many applications. The problem seeks to pack a given set of rectangles into a strip of given width in order to minimize its length. Some applications in which the strip packing problem arises are: Cutting pieces from wooden boards, cutting pieces from glass or steel sheets, optimal layout of ind...

Commercial lipase, glycerol kinase (GK), glycerol-3-phosphate oxidase (GPO) and peroxidase (POD) have been co-immobilized covalently on to arylamine glass beads affixed on a plastic strip through diazotization with a conjugation yield of 89.1 mg/g support and 64.1% retention of specific activity. The co-immobilized enzymes showed maximum activity at pH 7.5, when incubated at 40 degrees C for 20...

The linear response of a thin superconducting strip subjected to an applied perpendicular time-dependent magnetic field is treated analytically using the method of matched asymptotic expansions. The calculation of the induced current density is divided into two parts: an “outer” problem, in the middle of the strip, which can be solved using conformal mapping; and an “inner” problem near each of...

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...

This paper describes a generalisation of the Phase Gradient Autofocus (PGA) algorithm that allows strip-map operation. A standard autofocus technique, PGA, uses prominent points within the target scene to estimate the point spread function of the system. PGA was developed for tomographic mode spotlight synthetic aperture radar (SAR) but has limited applicability for side-scan synthetic aperture...

Let λ be a partition, and denote by f λ the number of standard tableaux of shape λ. The asymptotic shape of λ maximizing f λ was determined in the classical work of Logan and Shepp and, independently, of Vershik and Kerov. The analogue problem, where the number of parts of λ is bounded by a fixed number, was done by Askey and Regev – though some steps in this work were assumed without a proof. ...

The objective of this study was to screen for antigens of the hepatitis C virus (HCV) to establish a new double antibody sandwich-lateral flow immunoassay (DAS-LFIA) method for testing the presence of anti-HCV antibodies in human serum or plasma. A series of different recombinant HCV proteins in Escherichia coli cells were constructed, expressed, purified and the new DAS-LFIA strip was develope...

A semiquantitative strip immunoassay was developed for the rapid detection of imidacloprid and thiamethoxam in agricultural products using specific nanocolloidal gold-labeled monoclonal antibodies. The conjugates of imidacloprid-BSA, thiamethoxam-BSA and goat anti-mouse IgG were coated on the nitro-cellulose membrane of the strip, serving as test lines and control line, respectively. The flow o...
