Abstract Background Cardiopulmonary exercise test (CPET) provides several variables (V) that are strong predictors of events in patients (pts) with heart failure (HF). Purpose Our aim was to develop and evaluate the predictive power (PP) a CPET-based score, comparing Heart Failure Survival Score – HFSS. Methods Retrospective evaluation adult pts HF submitted CPET tertiary center. Pts were follo...

How to design a broad bandpass filter in the X-frequency range? The design procedure is developed from synthesis to electromagnetic simulation. The filter to be designed is implemented in waveguide technology with inductive irises coupling sections. So as to evaluate equivalent susceptance of iris aperture, two methods were used: the first one is based on classical mode matching techniques, whe...

This paper describes the comparision of a microstrip-fed monopole ultra wideband antenna with and without notch. In case of notch the notch-band characteristics is achieved by Cshaped ring resonator. The paper gives better understanding of antenna parameters such as return loss, VSWR etc., and its variation in performance of antennawith and without notch. Also presents the effect of parameters ...

In this paper, we analyze the electromagnetic response of a metamaterial slab in the case of normal incidence using the point-dipole interaction model and an expansion of polarization by eigenmodes. The problem is simplified by assuming that the lattice dimensions are smaller than a half wavelength and invoking the nearest neighbor approximation. In this manner, we find the structure supports t...

This paper describes the design and simulation by HFSS simulator of a probe-fed Planar Inverted-F Antenna (PIFA) for the use in PCS band [1850 MHz 1990 MHz]. A methodology based on parametric simulations (parameters are ground plan dimensions, height of radiating plate, feeding point position, shorting plate dimensions and positioning) was used to design optimized antenna. The simulation allowe...

Using LTCC (Low temperature co-fired ceramics) system in wireless packaging applications is wide used today. The properties requirements for wireless applications are requiring low loss at high frequencies and good characteristic comparative to cost. Several designs of packaging systems are presented in various microwave packaging applications such antenna. The relative curves of dielectric con...

Whip type antennas are probably the most commonly used antennas in portable RF systems, such as cordless and cellular phones, RF enabled laptop computers, , and handheld computers. Whip antennas are almost always mounted on the chassis which contains the radio and other electronics. Normally in mobile phone two set of antenna used for receiving different application such as GSM and GPS. In this...

In this paper a new structure for RF MEMS switches is proposed. This structure is introduced to remove self-actuation and latching phenomena. Particle Swarm Optimization (PSO) algorithm is utilized to obtain optimum results automatically. Also a method is described to reduce computational costs of the problem. Based on the executed simulations by HFSS, the designed switch shows 14 dB isolation ...
