This paper reports a new class of compact inline dual-band bandpass filters using TM-mode dielectric resonators in planar configuration. Thanks to the employment dielectric-loaded waveguide configuration and dual-mode TM120 TM210 resonances, substantial size miniaturization volume saving (>70%) can be obtained comparison with conventional technology. Additionally...

This letter presents the design of a novel dual-mode dual-band bandpass filter that utilises TM210 and TM020 modes cylindrical cavity resonators for millimetre-wave operation when fed with standard WR-10 waveguide ports. In this manner, two selected are demonstrated as single propagation path fixed dual-passband responses without need perturbations or tuning screws. The passbands designated cen...

The garbage collector presented in this paper makes use of two well known compaction garbage collection algorithms with very diierent performance characteristics: Cheney's two-space copying collector and Jonker's sliding compaction collector. We propose a scheme which allows either collector to be used. The run-time memory requirements of the program being executed are used to determine the mos...

We show that spiral vortices in oscillatory systems can lose stability to secondary modes to form dual-mode spiral vortices. The secondary modes grow at the vortex core where the oscillation amplitude vanishes but are nonlinearly damped by the oscillatory mode away from the core. Gradients of the oscillation phase, induced by the hosted secondary mode, can lead to additional hosting events that...

at the present work, the effect of cold exhaust gas recirculation (egr) on combustion and pollution of a dual fuel engine has been investigated by cfd code fire. the turbulent flow within the combustion chamber is simulated using the k-ε turbulence model, which is modified for engine flows. “wave” and “eddy break up” models are employed to predict combustion and spray process. the calculations ...

objective(s): a novel iq-specttm method has become widely used in clinical studies. the present study compares the quality of myocardial perfusion images (mpi) acquired using the iq-specttm (iq-mode),conventional (180° apart: c-mode) and l-mode (90° apart: l-mode) systems. we assessed spatial resolution, image reproducibility and quantifiability using various physical phantoms. materials and me...

The CMOS based dual mode logic gates containing two operating modes: 1) static mode 2) dynamic modes. Features of dual mode logic gates are low power dissipation in static mode and high performance in dynamic mode. This methodology is used to minimize the delay and improve the speed of the logic gates and an additional clocked transistor is used in this methodology. It provides the very high le...
