Developing an inkjet printer IV: printer mechanism control for best print quality

Inkjet printer motor control consists of moving the printhead in the scan direction and in the process direction. Both movements have different objectives. Scan direction movement needs to have constant velocity and process direction movement needs to have accurate movement. In this paper, we discuss a method for controlling the velocity of the printhead and how to tune the motor control parameters. We also design six test pages for testing accuracy of the printhead movement and cartridge properties. For each test page, we discuss expected prints, common printer control problems that could alter the print quality, and how to identify them.

DESIGN OF MOBILE EXPERT SYSTEM FOR DIABETES RISK DIAGNOSIS AND INFORMATION

Along with the development of information technology, mobile applications are widely applied to various fields. The use of mobile applications is considered effective to help user in understanding the problem. One example of the application of mobile applications needed today is an application that can help to determine a wide range of health. The designs discussed in this paper are the structure of the navigation and layout design of mobile applications created. There is a navigation structure and eight layout designs such as splash screen page, main menu page, diabetes risk test page, result page, diabetes prevention info page, food information page, list of hospitals page, and help page. The purpose of this paper is to design of mobile application for diabetes risk diagnosis and information based on android.

Similar MÜller-Lyer Effects from Operant and Comparison Response Modes

A one-sided (monopole) version of the Müller-Lyer was used to assess the effect of response mode on the metric distortion associated with the illusion. Two different response modes were tested for comparability. The Operant Mode required the judgment of stimulus span to be indicated by marking a dot on the test page. The Comparison Mode required judgment of equality of two adjoining prepositioned spans. The perceptual effects with the comparison procedure are known to consist of underestimation of spans which are bounded by concave fin-sets and overestimation of spans which are bounded by convex fin-sets. The question is whether the motor demands of the operant task produce an additional source of metric bias. Analysis indicate a very high correlation of judgments for the two modes of testing. Also, data with either mode of responding closely fit a linear model of the effect, and the model provides comparable index values for the concave and convex versions. These results should mitigate concern about potential motor bias from the operant method and encourage its use as a more efficient procedure for assessing metric distortion.

Changes in breath 13CO2/12CO2 consequent to exercise and hypoxia

Wasserman. “Changes in breath 13CO2/12CO2 consequent to exercise and hypoxia.” Page 936, right column, sentence beginning on line 8 should read: We therefore wondered if changes in EN could be used to detect changes in endogenous substrate oxidation during exercise. Page 940, right column, sentence beginning on line 15 should read: We controlled for potential acute modulators of oxidative fuel mix (e.g., meal and activity) by the overnight fast and avoidance of strenuous activity 24 h before each test. Page 941, left column, sentence beginning on line 27 should read: In summary, Vo2 adjusts slightly more rapidly than Vco2 in the transition from rest to exercise, whereas 13CO2 adjusts much more slowly. Page 938, Table 3 footnote should read: Values are group means for individual responses averaged from 5 to 20 min of exercise. n = 7 except for WR-3 where n = 6. Hypoxia represented FiO02, = 0.15, room air FiOO2, = 0.207. *Significantly di fferent from both WR-1 conditions and WR-2 in room air (P < 0.05). Note that work above LT (WR-2 in hypoxia and WR-3) resulted in a significant increase in R.

Five Forms of Written Feedback to Homework in a Mathematics Course for Elementary Teachers

The form of teacher feedback to students' written work has been an independent variable in previous research. The value of written feedback to student errors on test papers and homework has been established in several studies (Hedl, 1969; Karabinus, 1966; Page, 1958). In one investigation, written feedback specific to student errors on test papers was found to be superior to general feedback as measured by a subsequent achievement test (Page, 1958). On the contrary, in a study by one of the investigators, achievement scores favored general feedback over specific feedback in a CAI unit (Schoen, 1972). Attitude toward the CAI unit in the same study strongly favored groups whose feedback contained first names over the absence of the name.
