abstract the proper management of a watershed depends on recognition of effective elements and investigation of their behavior in different conditions. till date, many researches have studied the role of topographical general characteristics on hydrologic behaviors. whereas, the changeability of hydrologic properties under different conditions, especially in iranian watershed has been rarely ta...

The search task of Luck, Hillyard, Mangun and Gazzaniga (1989) was optimised to test for the presence of a bilateral field advantage in the visual search capabilities of normal subjects. The modified design used geometrically regular arrays of 2, 4 or 8 items restricted to hemifields delineated by the vertical or horizontal meridian; the target, if present, appeared at one of two fixed position...

İstanbul’s Hagia Sophia is a monumental structure with multiple sub-spaces coupled to one another through arches. Its architectural elements have undergone alterations as its function has changed from that of church mosque, mosque museum, and back mosque. This study makes use Sophia’s rich formal material characteristics conduct comprehensive investigation room acoustics coupling. The methodolo...

Smooth slopes can be displayed on treadmills through tilt mechanisms , but these mechanisms are typically too slow to present sudden slope changes. The Sarcos Treadport utilizes a mechanical tether that can apply horizontal forces to the user to simulate gravity forces. Psychophys-ical results are presented to show that slope display via tether forces is a reasonable facsimile for treadmill slo...
