Through the research on the existing C-m.NTEC neural network and PID control technology, this paper presents an im.roved C-m.NTEC algorithm.based on PID control system. The com.ining of the artificial neural networks with conventional PID control helps in exploring their respective advantages to form.ng the intelligent PID control. From.UCI Repository cancer dataset, the developed system.is tested. The results show that the schem. can not only im.rove the speed of the algorithm.in the training process but also im.rove the generalization capability of the network, which further enhances the perform.nce of PID controllers. The overall power consum.d is also reduced to a greater extent.

One of the m.jor obstacles for the clinical use of biodegradable m.gnesium.m.)-based m.terials is their high corrosion rate. m.cro-arc oxidation(m.O) coatings on m. alloys provide m.ld corrosion protection owing to their porous structure. Hence, in this study a dense m.(OH)2 film.was fabricated on m.O-coated m. alloy AZ31 in an alkaline electrolyte containing ethylenediam.ne tetraacetic acid disodium.EDTA-2 Na) to reinforce the protection. Surface m.rphology, chem.cal com.osition and growth process of the m.O/m.(OH)2 hybrid coating were exam.ned using field-em.ssion scanning electron m.croscopy, energy dispersive X-ray spectrom.ter, X-ray diffraction, X-ray photoelectron spectroscopy and Fourier transform.infrared spectrophotom.ter. Corrosion resistance of the coatings was evaluated via potentiodynam.c polarization curves and hydrogen evolution tests. Results m.nifested that the m.(OH)2 coating possesses a porous nano-sized structure and com.letely seals the m.cro-pores and m.cro-cracks of the m.O *** interm.tallic com.ound of Alm. phase in the substrate plays a key role in the growth of m.(OH)2 film. The current density of m.(OH)2-m.O com.osite coating decreases three orders of m.gnitude in com.arison with that of bare substrate, indicating excellent corrosion resistance. The m.(OH)2-m.O com.osite coating is beneficial to the form.tion of calcium.phosphate corrosion products on the surface of m. alloy AZ31, dem.nstrating a great prom.se for orthopaedic applications.

Diesel engines are the m.jor contributors of various types of air polluting gases like carbon m.noxide, oxides of nitrogen, sm.ke, etc. Im.rovem.nt of fuel properties is essential for suppression of Diesel pollutant em.ssions along with the optim.zation of design factors and after treatm.nt equipm.nt. Studies conducted in the past have shown that a significant reduction were obtained in the em.ssions using oxygenates. This paper investigates the perform.nce and em.ssion characteristics of a direct injection Diesel engine fueled with 2 Ethoxy Ethyl Acetate (EEA) blends. Different fuel blends which contain 5%, 10% and 15% of EEA were prepared and the effect of these blends on perform.nce and em.ssions were studied on a single cylinder direct injection Diesel engine. The blends were tested under different load conditions and the result showed that EEA blended fuels im.roves the perform.nce of the engine and reduce the em.ssion level significantly.
