Instruction dependency introduced by conditional branch instructions, which is resolved only at run-time, can have severe performance impact on pipelined machines. A variety of strategies are in wide use to minimize this impact. Additional instruction-traffic generated by these branch-strategies can also have an adverse effect on the system performance. Therefore, in addition to the likely redu...

Machines are good at handling huge amounts of data, but they lack the fl exibility and sensitivity of human perception when making decisions or observations. To understand human perception, we look toward what defi nes being human. To sense, observe, and make sense of the world around us, we combine our biological receptors (eyes, ears, etc.) with our cognitive faculties (memory, emotion, etc.)...

In order to optimize the usage of testing efforts and to assess risks of softwarebased systems, risk-based testing uses risk (re-)assessments to steer all phases in a test process. Several risk-based testing approaches have been proposed in academia and/or applied in industry, so that the determination of principal concepts and methods in risk-based testing is needed to enable a comparison of t...

The present study examines the role of Gal’perin’s Concept-based Instruction (CBI) as a pedagogical approach in teaching cognitive grammar-based (CG-based) concepts of tense and aspect to EFL students. Following the sociocultural theory of L2 Acquisition (SCT), arming L2 learners with scientific concepts can lead to L2 development by deepening their understanding and raising awareness of L2 str...

Fundamental to research at the Institute of Design is generation of a carefully constructed, robust question. This question emerges from the faculty developed research agenda with its five domains of interest matrixed against three research foci. Central to the development of particular research from this matrix is the generation of research questions. The question-based approach provides two s...

This paper describes an instructional approach designed to teach adults in a workplace training program strategies for communicating in an electronic context. Students used an on-line discussion group to respond to cases that were relevant to their experiences of seeking and preparing for employment. A scaffolded teaching approach was used whereby students were taught to explain or express a vi...

in this study two modes ofreading (car and traditional print mode) were compared in regards to their effectiveness for l2 reading comprehension. a group of 120 english major students were divided into three classes: car, traditional, and control. based on the english proficiency scores each class was divided into two groups (high and low levels of proficiency). three classes were taught by the ...

OBJECTIVE To evaluate whether computer-based learning (CBL) improves newly acquired knowledge and is an effective strategy for teaching prenatal ultrasound diagnostic skills to third-year medical students when compared with instruction by traditional paper-based methods (PBM). STUDY DESIGN We conducted a randomized, prospective study involving volunteer junior (3(rd) year) medical students co...
