Atmospheric Water Generators (AWG) are a promising technology solution to the water scarcity in world. However, their main drawback is high power consumption. This paper presents experimental optimization process of Portable Generator (PAWG) prototype based on thermometric cooler. was developed by an exhaustive search space, which generated parametric sweeps two parameters (i.e., control voltages PAWG), related consumption PAWG and physical variables involved condensation airflow temperature...
Kounis syndrome (KS) is a rare characterized by the co-occurrence of acute coronary syndromes in setting mast cell and platelet activation response to hypersensitivity reactions. It can be manifested as vasospasms, myocardial infarction, or stent thrombosis triggered drugs, vaccines, foods, stents, insect bites. life-threatening condition that needs adequately recognized for early diagnosis appropriate treatment. In this case report, we present 71-year-old patient with history arterial...
The Class-E with finite feed inductance is a high-efficiency power amplifier that generally uses complex, long, and iterative design procedures. In this paper, we detail methodology based on an analytical model of amplifier. This explores the by use symbolic mathematical tool, which was developed in software Maple™. approach helps to understand circuit topology it offers fast easy procedure without having examine, in-depth, equations.
Aloe Barbadensis Miller, commonly known as vera, has been widely used in different applications, such medicinal treatments and cosmetic products. However, its transportation handling present challenges due to oxidation property loss caused by direct environmental exposure. A strategy mitigate these effects is dehydration, where industrial-scale methods freeze-drying, spraying, refractory windows, convective drying can be applied. Despite their effectiveness, those dehydration techniques are...
This paper presents an iterative design methodology of the Class-E power amplifier, which assumes RF-choke instead a finite feed inductance to calculate values initial components amplifier. The proposed method modified these through systematic parametric sweep and capacitor in parallel switch. After few iterations, guarantees high efficiency under zero voltage derivative switching conditions. was tested by study case, specifications were based on class 0 transmitter standard Qi. simulated...
In this paper, a novel SIBO (Single-Inductor Bipolar-Output) DC/DC Boost converter is proposed to power OLED (Organic Light-Emitting Diode) microdisplays. The topology merges conventional SISO Single-Output) and switched capacitor inverter produce without both the cross-regulation effect unbalanced output voltages. Moreover, its control circuit efficiency are almost same as converter. Therefore, maintains density, small form factor, high of counterpart. was analyzed under...
This paper proposes an analytical expression set to determine the maximum values of currents and voltages in Class-E Power Amplifier (PA) with Finite DC-Feed Inductance (FDI) under following assumptions—ideal components (e.g., inductors capacitors infinite quality factor), a switch zero rise fall commutation times, on-resistance, off-resistance, loaded factor output resonant circuit. The developed expressions are average supply current, RMS (Root Mean Square) current through DC-feed...
This paper explores the design of a Class-E amplifier with finite DC-feed inductance using three tuning methods. Furthermore, this work quantifies impacts process (referred to in as effect) on main figures merit (FoMs) amplifier. The goals were guarantee two conditions: zero voltage and derivative switching (i.e., soft-switching tuning). To best authors’ knowledge, systematic methods have not been analyzed before for topology. Two them are based iterative component process, they explored...
