Stereoscopic vision is extremely precise in detecting minute diierences between adjacent depth planes, but quite imprecise in estimating absolute depth. In this paper, we address the issue of the spatial acuity (and not the stereo acuity) of stereopsis. Static RDS (random dot stereograms) stimuli were used to nd the spatial grain in which human stereoscopic vision operates. Using psychophysical...

Automatic hydraulic press is widely used for pressing ceramic wall and floor tiles, the four columns of its frame withstand the all work force when it works, so the columns are the key compartments of the frame, and its work performance has an important impact on the structural performance of the entire automatic hydraulic press. Took the column thread connection of 32.8MN automatic hydraulic p...

fiber reinforced polymers (frp) have widely used for the purposes of enhances strength and ductility of concrete columns. proper design of such hybrid columns, however, requires a better recognition of the behavior of concrete columns confined with frp. in this paper, the influence of frp thickness, concrete compressive strength, and column size on the performance of eccentrically loaded reacti...

A common notion of vision, consistent with this excerpt from the first paragraph of David Marr’s seminal book [1], is gained by considering the predicament of a person with a searchlight placed in a pitch-dark room full of unfamiliar furniture. One would hope that, by swinging the beam around, the observer will be able to recognize the objects present in the room (a cat here, an aquarium there,...

presence of arsenic, a heavy metal, in soil and water resources originating from geological formations of qorveh plain, which is considered as the main agricultural zone of kurdistan province in western iran, has put the agricultural products of this region at risk of pollution. since arsenate, as the most abundance form of arsenic in soil environment, competes against phosphate anion; applicat...

Use and opinion of herbs among medical students of Imo State University Nigeria was assessed. Information on herb use, indication and opinion from returned self-administered questionnaire was analyzed. A total of 114 students (91.2%) of 125 responded. 32 (28.1%) students had used herbs before, a significant proportion being males (OR 3.7). Herbal tea was the most popular herb used; maintaining ...

INTRODUCTION The efficiency of postoperative handover of paediatric patients to the children's intensive care unit (CICU) varies according to institutions, clinical setup and workflow. Reorganisation of handover flow based on findings from observational studies has been shown to improve the efficiency of information transfer. This study aimed to evaluate a new handover process based on recipien...

buckling instability is the most important factor at columns failune. icauses large deflection and mostly is analysed by first yield criterion. due fo some difficulties in application of the criterion, soecially in inelastic columns, a new method, namely geometric criterion is introduced in this paper to improve the buckling analysis of real columns. in this research project a number box- secti...
