3 Corresponding Author Robust PID Control in Chemical Process Industries Rakesh Joshi, Kostas Tsakalis, J. Ward MacArthur, Sachi Dash Abstract Robust control design has been increasingly used in industrial settings by leading automation companies. The design procedure has evolved in the last decades and fairly automated procedures exist now for use by practicing engineers or even operators. One...

Learning is the nature for human being. For example, a school-student learns a subject by doing exercise and home-work. Then, a school-teacher grades the school-student’s works. From this student and teacher interaction, the ability of the student mastering the subject is a feedback that the previous teaching method is successful or failure. As a result, the teacher will change the teaching met...

In 2011, practitioners and advocates of Integrated Pest Management (IPM) find themselves addressing agricultural, societal, and political pressures worldwide resulting from human population growth. This growth brings simultaneous burdens of sustaining a steady food supply; these include preventing losses from pests, dealing with increased human global travel, which in turn intensifies opportuni...

In this paper the simulation results of the adaptive control inside the tubular chemical reactor with counter-current cooling in the jacket is shown. The adaptive controller is based on the choice of the External Linear Model as a linear representation of the originally nonlinear system parameters of which are identified recursively. The polynomial method together with spectral factorization an...

Lignin is a complex, branched polymer that reinforces plant tissue. Understanding the factors that govern lignin structure is of central importance to the development of technologies for converting lignocellulosic biomass into fuels because lignin imparts resistance to chemical, enzymatic, and mechanical deconstruction. Lignin is formed by enzymatic oxidation of phenolic monomers (monolignols) ...

in order to investigation the effects of different combination and amount of chemical, biological and organic manure in present of water absorbent materials on some phenological, morphological and yield of soybean, a field study was carried out gorgan region climate conditions in a factorial experiment based on randomized complete block design with three replications. in this experiment two lev...

An experiment was conducted as randomized complete block design with three replications and 14 fertilizer treatments in year 2014. The treatments were including the control, application of chemical fertilizers according the soil analysis, application of 15, 30 and 45 tons of municipal  waste compost per ha as simple and with 25, 50 and 75% of chemical fertilizers. The results revealed that the ...
