Anticorrosive properties of olive oil polyurethanamide/ZnO biocomposite coatings
Manawwer Alam,Naser Mohammed Alandis,Eram Sharmin,Fahmina Zafar,Mohammad Asif Alam 한국화학공학회 2016 Korean Journal of Chemical Engineering Vol.33 No.5
Olive oil based polyurethanamide/ZnO biocomposites were prepared by energy efficient microwave irradiation technique. The biocomposites showed good coating properties: scratch resistance, impact resistance, adhesion and flexibility retention. The corrosion studies carried out by potentiodynamic polarization measurements exhibit inhibition efficiency of 99.99% in 5% NaCl, 99.99% in 3.5% HCl, and 99.94% tap water, respectively. The overall approach is significant as it focuses on the utilization of vegetable oil, a sustainable material, polyurethanamide, synthesized through an energy efficient technique, at lower temperature, in lower reaction time, promoting value addition through simple chemistry. The coatings provide corrosion protection by barrier action.

Design a robust artificial intelligent nonlinear controller for second order nonlinear uncertain dynamical systems is one of the most important challenging works. This paper focuses on the design of a robust chattering free mathematical model-base artificial intelligence (fuzzy inference system) variable structure controller (MFVSC) for highly nonlinear dynamic continuum robot manipulator, in presence of uncertainties. In order to provide high performance nonlinear methodology, variable structure controller is selected. Pure variable structure controller can be used to control of partly known nonlinear dynamic parameters of continuum robot manipulator. In order to reduce/eliminate the chattering, this research is used the artificial intelligence (fuzzy logic) theory. The results demonstrate that the model base fuzzy variable structure controller with switching function is a model-based controllers which works well in certain and partly uncertain system. Lyapunov stability is proved in mathematical model-based fuzzy variable structure controller with switching (sign) function. This controller has acceptable performance in presence of uncertainty (e.g., overshoot=1%, rise time=0.9 second, steady state error = 1.6e-8 and RMS error=4.8e-8).

In September 2017, an outbreak with high mortality, which showed the typical signs of ND, occurred among a flock of more than 2000 Eurasian collared doves in Konarak, southeast of Iran. A confirmed pigeon paramyxovirus type 1 strain was isolated from the brain tissues of the dead doves. The isolate, which was called Pigeon/Iran/Konarak/Barin/2017, was classified as a highly velogenic NDV. Complete genome sequencing and phylogenetic analysis showed that the isolate belonged to subgenotype XXI.2, which has never been reported from Iran before. The isolate had the highest homology (96.15%) with early 2010s Italian isolates. Further studies will be required to understand the diversity better.

Most of controllers need real time mobility operation so one of the most important devices which can be used to solve this challenge is Field Programmable Gate Array (FPGA). FPGA can be used to design a controller in a single chip Integrated Circuit (IC). To have higher implementation speed with good performance cMinimum Control Unit (MCU) is implemented on Spartan 3E FPGA using Xilinx software. Design a 4 bits Field Programmable Gate Array (FPGA)- based carry lookahead MCU is the main challenging works. MCU is control unit to control of data transfer between input and output and process the input data. In this research, MCU is used to control the 4 bits, Arithmetic Logic Unit (ALU). Combinational logic characterized by its propagation delay and contamination delay. To reduce the delay hardware description language (HDL) type of programming is very important. To reduce the route delay and logic delay, type of HDL design is very important. In this research, we used lookahead design, which reduce about 10% delay in comparison with ripple carry.
