this study investigated 1) whether the effect of teacher-developed graphic organizers vis-à-vis student-developed ones was more significant on improving intermediate efl learners’ writing, and 2)whether the use of both graphic organizers had any impact on their writing. the participants were selectedin two stages: 130 students sat for a piloted proficiency test. those who scored above half ofth...

We describe a new steerable projector, whose projection center precisely corresponds with its rotation center, which we call a “fixed-center pan-tilt (FC-PT) projector.” This mechanism allows it be set more easily to display graphics precisely on the planes in the environment than for other steerable projectors; wherever we would like to draw graphics, all we have to do are locate the FC-PT pro...

A simple modification of Horn's circle drawing procedure yields a disk generator for a class of graphic devices capable of drawing rectangular areas. Another variation produces a disk a scan-line at a time allowing it to be drawn at the refresh rate of the display. The calculations involve only additions and binary shifts.

An implementation of vector-based amplitude panning (VBAP) for spatial display of sonified data is presented. The proposed method offers an implicit conversion from Spherical to Cartesian coordinates thus being particularly well suited for auditory display. Two techniques from computer graphics are adapted in order to predefine an optimum set of speaker triplets and perform the amplitude pannin...

It is well recognized that performance changes over time. However, the effect of these changes on overall assessments of performance is largely unknown. In a laboratory experiment, we examined the influence of salient Gestalt characteristics of a dynamic performance profile on supervisory ratings. We manipulated performance trend (flat, linear-improving, linear-deteriorating, U-shaped, and inve...

For manufacturers of microelectronic systems such as smart phones, tablets, and other mobile computing devices and for SoC (system-on-a-chip) designers, manufacturers, and vendors, system power consumption represents a major consideration. SoC designers must optimize power within SoC units, such as CPUs, graphic controllers, display controllers and memory controllers. However, on modern mobile ...

PARSESNP is a tool for the display and analysis of polymorphisms in genes. Using a reference DNA sequence, an exon/intron position model and a list of polymorphisms, it determines the effects of these polymorphisms on the expressed gene product, as well as the changes in restriction enzyme recognition sites. It shows the locations and effects of the polymorphisms in summary on a stylized graphi...

the relationship between the manufacturer and supplier has changed from one of competition into that of greater cooperation during recent years. the selection and evaluation of suppliers are primary and important issues when an enterprise implements supplier relationship management (srm) and total quality management (tqm). much research indicates that most enterprises tend to evaluate their sup...

An elementary lift of a binary matroid M that arises from coextension can easily be obtained by applying the splitting operation on M. This graphic may not produce matroid. We give method to determine forbidden minors for class matroids such any set k elements is again Using this method, we obtain k=2,3,4. One compute k≥5. As consequence, whose all lifts via coextensions are also graphic. There...

In this paper, we propose a new concept of visual/haptic interfaces called WYSIWYF display. The proposed concept provides correct visual/haptic registration using a visionbased object tracking technique and a video keying technique so that what the user can see via a visual interface is consistent with what he/she can feel through a haptic interface. Using Chroma Keying, a live video image of t...
