In this paper, a compact notched ultra-wideband (UWB) bandpass filter with improved out-of-band performance using quasi electromagnetic bandgap (EBG) structure is proposed. Firstly, a UWB bandpass filter based on a stepped-impedance stub-loaded resonator (SISLR) is combined with quasi-EBG structures, which suppress the undesired spurious bands to improve the out-of-band performance. In order to...

In this paper Cobalt-Chromium-Molybdenum (Co-Cr-Mo) specimens produced by Selective Laser Melting (SLM) for biomedical field were studied. particular, fatigue tests carried out comparing as-built condition with Hot Isostatic Pressing (HIP) and a heat treatment under vacuum condition. The influence on microstructure properties was investigated plain V-notched geometry. Both HIP had effects the i...

Polycarbonate (PC) has a wide range of applications in the electronic, transportation, and biomedical industries. In addition, investigation on applicability to use PC superstrate photovoltaic modules is ongoing research. this paper, envisioned be used as material for structural components renewable energy systems. Usually, have geometrical irregularities, i.e., notches, are subjected severe me...

background: the study of electrocardiographic parameters of buffalo in comparison to other large animals is very scanty. electrocardiography is a very important tool to diagnose cardiac diseases. in this case, standardization of ecg of each species of animal or even each breed should be carried out. this is due to the fact that ecg parameters are related to many factors such as size, breed, sex...
