In this paper we establish a general algorithmic framework between bin packing and strip packing, with which we achieve the same asymptotic bounds by applying bin packing algorithms to strip packing. More precisely we obtain the following results: (1) Any offline bin packing algorithm can be applied to strip packing maintaining the same asymptotic worst-case ratio. Thus using FFD (MFFD) as a su...

An experiment investigating the elastic local buckling response of trough girders composed of thin profiled steel sheeting has been undertaken Beam tests were performed to promote initial local buckling in a region of constant moment in the elastic range of structural response. The results of the experiments were compared with an elastic complex semi-analytical finite strip method of analysis, ...

In this paper we analyze the numerical solution by a collocation method of a hypersingular integral equation resulting from the boundary value problem related to an infinite strip containing an edge crack perpendicular to its boundaries. Moreover, we show convergence results as well as numerical tests in a case of interest in fracture mechanics.

Various methods are available for isolating DNA fragments from agarose gels. For many purposes, particularly sub-cloning, quantitative recovery is not necessary as the amount of DNA needed for ligation is usually a small fraction of the amount that would be visible as an ethidium bromide stained band on the gel. The most commonly used methods suffer from one or more of a variety of disadvantage...

Micro Strip Antenna Array has been proposed with high efficiency for wireless communication. Micro strip antenna arrays are widely used in various applications like in wireless communication system, satellite communication, Radar systems, Global positioning systems, Radio Frequency Identification (RFID), Worldwide interoperability for microwave access (WiMax), Rectenna applications, Telemedicin...

A Bayesian approach alternative to the one used in strip-pair comparison method for developing threshold color-difference models is presented this paper. Strip-pair based on construction of color-control strips made pairs patches put contact and ordered by increasing CIELAB color difference. Observers are required indicate number pair every strip which they begin perceive a just noticeable Freq...

the spline finite strip method (s.f.s.m.) for buckling analysis of plates and plate assemblies subjected to longitudinal compression and bending, transverse compression as well as shear is described. the method allows for the boundary conditions. local buckling coefficients of plates with different boundary conditions under compression, bending and shear are calculated. convergence studies with...

This paper deals with local buckling analysis of rectangular functionally graded material plates using finite strip method and based on classical plate theory. The modulus of elasticity of the plate is assumed to vary according to a power-law distribution in terms of the volume fractions of the constituents. The principle of minimum total potential energy is employed to obtain stiffness and sta...
