Abstract Voltage type flux observer has attracted much attention because of its less mathematical calculations and ease implementation. The only issue with the estimation approach is integration mechanism; using a pure integrator may cause saturation DC bias issue, whereas low pass filter (LPF) self-adaptive band-pass (SABPF) would result in magnitude phase angle errors. This work offers an imp...

This paper introduces a compact microstrip low-pass filter (LPF) with very sharp rejection. The proposed LPF is designed to be used for electronic warfare in defense industry. It has 62 dB/GHz attenuation rate, 10 GHz of stopband width and 48.6 dB attenuation. Moreover, it also wide passband high cut-off frequency (f_c) 6 GHz. been fabricated using alumina (Al2O3) substrate titanium-gold (Ti-Au...

The nature of the helper lymphocytes in lymphocytosis-promoting factor (LPF)-induced proliferation was explored. Removal of macrophages from adherent splenocytes by either carbonyl-iron incubation or passage through Sephadex G-10 columns did not affect their synergistic function. Nor did cytolysis with Thy-1.2 antiserum and complement. The helper cells were found to be surface immunoglobulin-po...

Abstract An accurate, high‐speed, fully differential difference amplifier for current sensing utilizing the chopper approach was implemented in a 0.18 μm complementary metal‐oxide‐semiconductor (CMOS) technology. Unlike state‐of‐the‐art solutions, we use higher chopping frequency MHz range due to bandwidth requirements of introduced circuits latter application, namely, low‐side phase‐current me...

Since the food system will inevitably produce waste, it is recommended that be captured and recycled for more efficient use rather than being disposed of as solid household waste. Therefore, advantageous to promote waste poultry feed. In order study feeding feasibility a Lab- Prepared Feed (LPF) based on kitchen well their nutritional value, tests were carried out near Taza city an organic chic...

In this paper, a novel compact band pass filter (BPF) is proposed for Global Positioning System (GPS) receivers. The proposed BPF configuration is composed of a low pass filter (LPF) section formed by the coupled line transformer connected with a radial stub and two short circuited stubs embedded within the 50Ω microstrip line connecting the input/output (I/O) port of LPF. The lumped equivalent...

In personalized queues, information at the level of individuals – customers or servers – is affecting system dynamics. Such information is becoming increasingly accessible, directly or statistically, as exemplified by personalized/precision medicine (customers) or call-center workforce management (servers). In the present work, we take advantage of personalized information about customers, spec...

This article presents a simple and efficient method for spatialising sound in virtual environments by adding low pass filters (LPF) to the already widespread panning and attenuation techniques. Through two different experiments, variations in subject performance when locating sounds in a virtual environment between regular 3D audio from popular game engines (Unreal Engine and Unity) and our pro...
