This study reports a new microfluidic system integrated with a microfluidic control module and a micro electrochemical module for detection of urinary proteins. The integrated microsystem can automatically detect proteins in urine with a high sensitivity. The microfluidic control module consists of a new two-way, spiral-shape micropump which can transport the urine samples to the sensing regions. The net ionic charges of the protein samples can be detected while the samples flow through the sensing region of the micro electrochemical module. Two major urinary proteins including lysozyme and albumin are detected in a multiple-channel layout with little human intervention and are analyzed in a short period of time, while only consuming a 100-mul urine sample. The developed microfluidic system could lead to a convenient, yet crucial, platform for chemical and biological detection and diagnosis.

Aim at the effect of the control method in traditional metallurgy furnace temperature is not good, a self-tuning fuzzy PID control method combining fuzzy control with PID control was proposed in this paper based on the analysis of the advantages and disadvantages of the PID control and fuzzy control method, and a concrete control algorithm was put forward and simulation experiment was finished. The simulation results show that the effect of the controller is good, and the control of system is fast and smoothly according to it.

This study develops conventional use of 20 mm twin machine gun to provide defence against close-in-air threat. For expanding the field of usage of machine gun and promoting defence ability in naval combat, this study offers a preliminary design of tracking loop, which includes the man-in-loop's scheme. Accuracy and stabilisation are the main considerations for a shipboard weapon design and are included in design. In numerical simulations, /the stabilisation of gun mount and carriage platform in tracking loop under large disturbances induced by sea waves is assessed first. Two typical scenarios proceed with the testing of tracking performances. Simulation results demonstrate the effective performance of designed tracking loop subject to environmental disturbances.
