One hundred andflfty years ago, carbohydrates from plant matter In all forms proulded the raw materlals for many lndustrlal products. By the 1970s. howeuer, the carbohydrate had been dlsplaced by hydrocarbons as the molecular bulldfng block of our Industrial economy. Now. technologlcal advances, enulronmental regulatlons. and green consumerism haue set the stage for the carbohydrate economy to ...
This paper presents transient stability analysis and enhancement of Industrial Cogeneration Plant (ICP) using Artificial Neural Network (ANN) based adaptive load shedding. By selecting the total in-plant generation, spinning reserve, total plant load and rate of change of frequency as the input neurons of the ANN, the minimum amount of load shedding is determined to maintain in-plant load-gener...
The servomotor is an essential element in the automation of industrial processes, and its control is necessary to achieve better performance in applications of industrial positioning. In the systems control, the knowledge of plant model through proper identification is fundamental. This work presents a methodology based on neural networks to obtain the servomotors models on industrial applicati...
This paper poses and tests a new model of the location of plants that process ubiquitously supplied ‘von Thünen’ inputs such as raw farm output. The new model rationalizes why agro-industry is city-located but resource-oriented. It demonstrates the significance of relative transport costs in agroindustry location. Furthermore, we present a unprecedented direct test/empirical confirmation of est...
Coal based fired power plant is a very complex unit. Today’s electric energy is playing an important role in the industrial and all-round development of every country. It is desired form of energy, because it can be produced easily and transmitted economically. Further, it can be used efficiently and easily to domestic and industrial applications. Performance evaluation of such units is becomin...
the main objective of this study is the modelling and optimization of an industrial hydrocracker unit (hu) by means of adaptive neuro fuzzy inference system (anfis) model. in this case, some data were collected from an industrial hydrocracker plant. inputs of an anfis include flow rate of fresh feed and recycle hydrogen, temperature of reactors, mole percentage of h2 and h2s, feed flow rate and...
Industrial chemicals and materials are currently derived mainly from fossil-based raw materials, which are declining in availability, increasing in price and are a major source of undesirable greenhouse gas emissions. Plant oils have the potential to provide functionally equivalent, renewable and environmentally friendly replacements for these finite fossil-based raw materials, provided that th...
Background and purpose: It is likely that industrial workplaces increase the chance of developing obesity and cardiovascular disease risk factors in the employees. The aim of this study was to compare obesity and some health markers between male employees of gas refinery (first exposure group) and petrochemical staff (second exposure group) compared to non-industrial male employees of general p...
مراتع حدود نیمی از خشکی های جهان را در بر دارند و پوشش گیاهی آن در نتیجه تأثیر متقابل محیط و موجودات زنده به وجود آمده است و به عنوان یک اکوسیستم طبیعی مدیریت می شوند. علاوه بر مراتع، راه ها در عصر حاضر نیز از اجزا مهم و زیرساخت های اصلی زندگی نوین و توسعه کشورها به شمار می روند. جاده ها ساخته دست بشر هستند و جوامع گیاهی کنار جاده تحت تأثیر ساخت و ساز قرار دارند. پوشش "رودرال" به مجموعه ای از پ...
