Free-field release from masking was studied as a function of the spatial separation of a signal and masker in a two-interval, forced-choice (2IFC) adaptive paradigm. The signal was a 250-ms train of clicks (100/s) generated by filtering 50-microseconds pulses with a TDH-49 speaker (0.9 to 9.0 kHz). The masker was continuous broadband (0.7 to 11 kHz) white noise presented at a level of 44 dBA me...

this paper presents the numerical analysis of seismic soil-pile-superstructure interaction in soft clay using free-field soil analysis and beam on winkler foundation approach. this model is developed to compute the nonlinear response of single piles under seismic loads, based on one-dimensional finite element formulation. the parameters of the proposed model are calibrated by fitting the experi...

this study investigates the relationship between field-related cognitive styles and global reading comprehension of hypertext. technically, field dependency is prevailing dominance of field on perception of parts, while global comprehension is skim-like reading to grasp the general content. in this research project, 60 senior and junior students of arak university majoring in english literature...

تاثیر شرایط ساختگاهی در محیط ایزوتروپ جانبی مورد بررسی قرار گرفته است. این مطالعه بصورت مجزا از سازه های موجود در روی ساختگاه است، که در اصطلاح به چنین منطقه ای ((ناحیه آزاد)) ‏‎(free field)‎‏ گفته می شود. اهمیت این کار (بررسی دامنه تکانهای ناحیه آزاد) در بحث اندر کنش سازه و خاک خواهد بود. در ابتدا با نوشتن معادلات تعادل، سازگاری و معادلات رفتاری در محیط ایزوتروپ جانبی و در حالت دینامیکی به معا...

A bstract We study co-dimension two monodromy defects in theories of conformally coupled scalars and free Dirac fermions arbitrary d dimensions. characterise this family conformal by computing the one-point functions stress-tensor conserved current for Abelian flavour symmetries as well two-point displacement operator. In case = 4, normalisation these correlation are related to defect Weyl anom...
