background: the purpose of this study was to investigate the efficiency of flat sheet membrane bioreactor (fs-mbr) in bod 5 and cod removal of isfahan south municipal wastewater treatment plant. methods: in this study a submerged fs-mbr, with 140 liters volume was fed using microfiltration membrane (mf) during 109 days and hydraulic retention time of 20 hours. findings: the mbr application in m...

With the fast increase of the documents, using Text Document Classification (TDC) methods has become a crucial matter. This paper presented a hybrid model of Invasive Weed Optimization (IWO) and Naive Bayes (NB) classifier (IWO-NB) for Feature Selection (FS) in order to reduce the big size of features space in TDC. TDC includes different actions such as text processing, feature extraction, form...

Notes for a seminar in the IST TQFT Club about the Baez-Dolan groupoidification and its extensions, as applied to some toy models in physics.

The purpose was to show that when a favor reduces a person's freedom, it arouses "psychological reactance," a motivational state aimed at restoration of this freedom. Ss, run individually, learned they were to make Ist-imprcssion ratings of another S (confederate) and then were given a soft drink by this S, prior to making the ratings. In a 2 X 2 design, the Ist-imprcssion ratings were given lo...

: pulpotomy is an accepted treatment for the management of cariously exposed pulps in symptom free primary molars. the purpose of this study was to compare the clinical and radiological outcomes of three different single-visit vital pulp therapies including pulpotomy with electrosurgery (es), formocresol (fc) and ferric sulfate (fs) in cariously exposed primary molar teeth . materials & methods...

conclusion fs t2 w and ce fs t1 w sequences of axial planes were the most useful sequences in determination of active sacroiliitis. therefore, in patients with renal failure or allergy to contrast media, fs t2 wi can be obtained to detect active sacroiliitis. objectives the aim of this retrospective study was to assess the value of different magnetic resonance imaging (mri) sequences in evaluat...

In this note, we show that the impedance control strategy proposed in the paper is not feasible from practical implementation point of view. Next, a robust impedance controller is proposed for electrically driven robots using Fourier series (FS). The fact that robots' actuators have limited voltage is also considered in controller design procedure. In comparison with other impedance controllers...
