Parallel programming is characterized by a growing set of parallel architectures, paradigms and programming languages. The question how to support a programmer best in designing and implementing a parallel program is still an important topic of research. This is especially true when trying to utilize distributed memory machines (e.g. Transputers or workstation clusters). For many application ar...

In this paper, a compact microstrip diplexer is proposed for Wimax and DCS applications at 2.5 GHz and 1710-1880 MHz respectively. The microstrip diplexer consists of two band-pass filters operating at different frequency bands and a coupledjunction. Each filter is formed by a meander-line resonator and two Input/Output feed lines. The frequency response of each filter can be easily controlled ...

A new current structure for the fast traveling-wave 2.5MeV beam chopper in the front end of the Spallation Neutron Source (SNS) has been suggested in [1]. The structure is based on the meander-folded notched stripline with dielectric supports and separators. Its design has been optimized using electromagnetic 3-D modeling with the MAFIA code package to provide rise and fall times in the range o...

Two antenna designs were achieved for dual and wide band operation in wireless systems. One design was realized using a tapered meander slot with a microstrip feed to give dual band operation at 1.8 and 2.4 GHz. In this design both operating frequencies are controlled mainly by the horizontal slot width of the meander and the distance of the microstrip line termination from the slot. The other ...

A geometrical analysis of the meander decorative patterns on a Roman pavement mosaic found at the Roman villa in Chedworth, England, is presented. The analysis reveals that the intricate swastika meander pattern consisting of four closed curves could have been easily constructed using a very simple hypothesized algorithm. The algorithm also explains the design of Roman swastika meanders found t...

This paper presents the simulation and experimental study of the radiation pattern of a meander-line-coil EMAT. A wholly analytical method, which involves the coupling of two models: an analytical EM model and an analytical UT model, has been developed to build EMAT models and analyse the Rayleigh waves' beam directivity. For a specific sensor configuration, Lorentz forces are calculated using ...

This paper proposed a novel broadband Planar Inverted-F Antenna(PIFA) for IMT-2000/WLAN/DMB terminal. Two branch lines for meander line were utilized in order to improve the characteristics of PIFA which usually has a narrow band. The shorting strip between the ground plane and meander-type radiation elements were used in order to minimize the size of the antenna. The −10dB return loss bandwidt...

We construct a Brownian path conditioned on its minimum value over a xed time interval by simple transformations of a Brownian bridge. Path transformations have proved useful in the study of Brownian motion and related processes , by providing simple constructions of various conditioned processes such as Brownian bridge, meander and excursion, starting from an unconditioned Brownian motion. As ...
