The Influence of Plain Bearings on Shaft Whirling

Influence of unsuitable operational conditions on the transient performance of a small hydrogen liquefier

Joule-Thomson cooling systems are used in refrigeration processes such as cryogenic gas liquefaction. Although extensive studies have been carried out by researchers, most of them include cryogenic heat exchangers and their associated fields. In the current study, an attempt was made to indicate the effect of using inappropriate operational conditions in a cryogenic Joule-Thomson cooling system...

the influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry

بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...

Dehydrogenation of Propane to Propylene Over Pt-Sn/Al2O3 Catalysts: The influence of operating conditions on product selectivity

Modeling and control of rotating shaft with magnetic bearings

The paper presents control system for positioning of rotating shaft ends with magnetic bearings. Problem of identification and modelling is presented as well as control algorithms. The main difficulty of the control are disturbances caused by rotation (controlled by push-pull drivers) of the shaft. Weighted minimumvariance controller has been applied and compared with built-in PD controllers. T...
