For some time I have been involved in efforts to develop computer-controlled systems for instruction. One such effort has been a computer-assistedinstruction (CAI) program for teaching reading in the primary grades (Atkinson, 1974) and another for teaching computer science at the college level (Atkinson, in press). The goal has been to use psychological theory to devise optimal instructional pr...

Hydroxyacetone (HA) is mainly produced in the atmosphere from oxidation of hydrocarbons of the type, CH3(R)C=CH2. Tuazon and Atkinson (1990) reported HA yield of 41% from the OH-initiated oxidation of methacrolein in the presence of NOx. Since methacrolein is a major product of isoprene oxidation (Carter and Atkinson, 1996), isoprene, a key biogenic hydrocarbon, is therefore expected to be an i...

In this study, a quasi-realistic thermodynamic analysis was performed to investigate the effects of design and operating parameters on performance single-cylinder modern Atkinson cycle engine. Fortran used for all calculations. It assumed that fuel-air mixture as working fluid, iso-octane fuel. The Wiebe function combustion process it specific heat fluid varies with temperature. calculations, t...
