Let t(n, d) be the minimum number t such that there are t of the n lattice points {(x1, . . . , xd) : 1 ≤ xi ≤ n} so that the ( t 2 ) lines that they determine cover all the above n lattice points. We prove that for every integer d ≥ 2 there are two positive constants c1 = c1(d) and c2 = c2(d) such that for every n c1n d(d−1)/(2d−1) ≤ t(n, d) ≤ c2n log n. The special case d = 2 settles a proble...

The production effect is the difference in memory favoring words read aloud relative to words read silently during study. According to a currently popular explanation, the distinctiveness of aloud words relative to silent words at the time of encoding underlies the better memory for the former. This distinctiveness is attributable to the additional dimension(s) of encoding for the aloud items t...

BACKGROUND This study was constructed as a comparison group pre-test/post-test quasi-experiment to assess the effect of the implementation of the PE curriculum by specialist PE teachers on children's physical development and physical fitness. METHODS 146 classes from 66 Slovenian primary schools were assigned to quasi-test (71) and quasi-control (75) groups. Data from the SLOFIT database was ...

Archived data from four courses taught with computer-aided personalized system of instruction (CAPSI) – an online, self-paced, instructional program – were used to explore the relationship between objectively rescored final exam grades, peer reviewing, and progress rate – i.e., the rate at which students completed unit tests. There was a strong positive correlation (r = .68, p < .01) between ra...

In order to satisfy qualifying exam requirements adhered to by the School of Informatics and Computing, I will provide an overview of global optimization techniques, specifically simulated annealing, genetic algorithms, and tabu seach.

background: ( h.pylori ) infection is a common bacterial infection in humans. approximately half of the helicobacter pylori people throughout the world are infected by this gastric microbial pathogen. the outcome of h.pylori infection varies from gastritis to peptic ulcers, duodenal ulcers and gastric malignancies. this study aims to estimate the prevalence of h.pylori infection and iron defici...

The perfusion education program at The Ohio State University uses a step exam to rank students and identify incompetent students in regard to the program learning objectives. The step exam determines student progress from the didactic to the clinical phase. Each student must pass the competency step exam to gain entry to the clinical rotations. The development, use, and results of the step exam...
