in many active noise control (anc) applications, an online secondary pathmodelling method that uses a white noise as a training signal is required. this paperproposes a new feedback anc system. here we modified both the fxlms and thevss-lms algorithms to raised noise attenuation and modelling accuracy for theoverall system. the proposed algorithm stops injection of the white noise at theoptimum...

this study explores the effect of online annotations via interactive white boards (iwbs) on reading comprehension of iranian efl learners. to this aim, 60 students from a language institute were selected as homogeneous based on their performance on oxford placement test (2014).then, they were randomly assigned to 3 experimental groups of 20, and subsequently exposed to the research treatment af...

introduction: diagnosing and treating diseases associated with amyloid fibers remain a great challenge despite of intensive research carried out. one important approach in the development of therapeutics is the use of herbal extracts which are rich in aromatic small molecules. cinnamomum verum extract (ce) contains proanthocyanidin and cinnamaldehyde, which have been suggested to be capable of ...

this study was carried out to evaluate the effects of satureja khuzistanica essential oils (skeo) on performance, serum metabolites and differential counts of white blood cells in broiler chickens. a total of 280 one-day-old straight-run cobb 500 broiler chickens were allocated into seven treatment groups with four replicates of 10 birds each from day 1 to 42 of age. the birds were continuously...

the objective of the present study was to determine the grades of nonspecific bacterial infection of genitalia of repeat breeding cattle by a simple and rapid test under field condition. for this purpose, a total of 100 crossbred jersey cows comprising of 80 repeat breeding animals presented for treatment and 20 normal cyclic (control group) animals presented for artificial insemination at thei...

the objective of this study was to determine the occurrence of antimicrobial resistance among staphylococcus aureus and to estimate the presence of methicillin-resistance in s. aureus (mrsa) isolates obtained by culture and polymerase chain reaction (pcr) methods. for this purposes, 100 iranian white and feta cheese samples collected from different suppliers were initially evaluated for the occ...

this study was conducted to investigate the effects of curcuma zedoaria and zingiber zerumbet on non-specific immune responses of grouper (epinephelus coioides). fish were fed an experimental diet containing 0, 0.5, 1.0, 2.5 g/kg of c. zedoaria and z. zerumbet mixed diets twice daily for two weeks. non-specific immune parameters such as respiratory burst activity, reactive oxygen species, phago...
