in this research, the effects of the addition of powdered activated carbon (pac) into the aeration zone of an activated-sludge (as) system for treating tehran oil refinery effluent, was investigated during more than 12 months in a pact pilot-scale model. besides the evaluation of organics removal efficiency and determination of basic design factors kinetic coefficients, a series of experiments ...

background : pain is one of the main protests of inflammatory diseases, hence, understanding the mechanisms which involved in the induction and persistence of pain is essential. microglia is a contributing factor in the onset and maintenance of inflammation. increased microglial   activation increases the level of central pro-inflammatory cytokines and the development of central sensitization f...

ae is a serious medical condition in which the immune system attacks the brain, impairing function. with rapid diagnosis and appropriate treatment, many patients recover most or all functions. however, not all patients experience full recovery; with approximately 6% mortality and other patients who never regain significant brain and/or bodily functions. autoimmune encephalitis can produce a wid...

1. the common image of tourism in iran, in high-level samples, is a guide that provides explanations about a building’s popularity among the spaces of a historical collection: construction year, regency, sizes, number of important components, general style and interesting stories that create a mysterious visage of the complex. the tourist however, after returning, forgets about the initial data...

Cloud manufacturing is defined as a relationship between the consumer and a flexible array of production services, managed by an intervening architecture that can match service providers to product and manufacturing processes Cloud manufacturing definitions typically make explicit or imply three groups of actors: consumers, who request and use cloud manufacturing processes; application provider...

We give a general overview of the state-of-the-art in subspace system identification methods. We have restricted ourselves to the most important ideas and developments since the methods appeared in the late eighties. First, the basis of linear subspace identification are summarized. Different algorithms one finds in literature (Such as N4SID, MOESP, CVA) are discussed and put into a unifyin...
