This thesis describes work done in two areas of compilation support for superscalar processors; register allocation and instruction scheduling. Chapter 1 describes an approach to register allocation for superscalar processors that supports dynamic and speculative out-of-order execution of instructions and guarantees precise interrupts without expensive hardware for managing register usage and m...

Although many studies demonstrate large learning gains when instruction includes diagrams, diagrams do not always lead to improved outcomes. How can instructional designers know whether a given diagram will enhance learning? We have developed a framework of three factors that influence the effectiveness of a diagram in a particular learning situation: the learning objective, the design of the v...

Studies have shown that when learning occurs in an environment that uses animated pedagogical agents and personalized instruction, the learner learns the material more deeply and can recall it easier when compared to learning without an agent. Thus, an effective learning system creates personalized contexts for each learner. The “one size fits all” concept is not very effective across a large n...

Reconfigurable instruction set processors can potentially reduce the power consumption of high performance multimedia applications by fusing the concept of a reconfigurable array with a programmable processor. In particular, VLIW processors with coarse-grained reconfigurable functional units are specially suited to low power multimedia applications. Code generation for this type of processors i...

the ultimate purpose in designing a curriculum should be to have an organized system of what is to be learned when an area of study is identified. the curriculum development should be designed in such a way that even the beginners are able to get a complete idea of the subject over a period of time on learning it. the curriculum should be as of that it should make him/her to get involved in kno...

portfolios as a means of constructivist learning appear to show great promise in enhancing diverse dimensions of learning and promoting learner motivation. this study is an investigation into the effectiveness of portfolio development on the reading comprehension and academic motivation of undergraduate students majoring in english literature in iran. in order to answer the research questions, ...

Transient circuit analysis is a particularly challenging topic in introductory circuit analysis courses. In illustrating the solution of transient analysis problems, many textbooks emphasize the procedure of problem solving. While such focus provides valuable training for students, we believe an in-depth understanding of critical concepts in transient process is crucial and needs to be emphasiz...

The management of uncertainty and imprecision is becoming more and more important in knowledge-based systems. Fuzzy logic provides a systematic basis for representing and inferring with this kind of knowledge. This paper describes an approach for fuzzy inference based on an uncertainty forward propagation method and a change in the granularity of the elements involved. The proposed model is abl...

The communicative approach in foreign language instruction arguably is supposed to approximate a real-world setting to certain extent; but, it all too often falls short of providing a realistic context for the language to be used in all its possible variations. The fact that languages are dynamic and change is rarely recognized outside of the classroom due to the static nature of texts and pre-...
