Background
Chagas disease (CD) serological screening at blood banks is usually performed by a single highly sensitive serological assay, with chemiluminescent immunoassays (CLIAs) being the method of choice. CLIAs employ recombinant, fusion peptides and/or chimeric antigens that selectively capture anti‐Trypanosoma cruzi antibodies. However, despite high sensitivity, the ability of these tests to...
In this paper a new analog behavioral model of a negative temperature coefficient thermoresistive sensor developed using SPICE for a hot-wire Wheatstone-Bridge Constant Temperature Anemometer is proposed. The analog model was developed using a capacitor and voltage and current dependent sources. This model is suitable for transient and steady-state time domain analysis. Sensor's behavior is detailed...
This paper proposes a new architecture of a controlled-temperature hot-wire anemometer using voltage feedback linearization. The voltage feedback linearizes the sensor input-output relationship and the controller is designed to achieve null steady-state error and reduce the system response time. Analysis of the behavior of the architecture modeled using Simulink is presented for a NTC sensor. Simulation...
