ATPG vectors for a combinational circuit exhibit correlations among the bits of a test vector. We propose a BIST/decompressor circuit design methodology using spectral methods which utilizes the correlation information. This circuit serves dual purposes. It generates BIST vectors that are similar to the ATPG vectors with higher test coverage as compared to random and weighted random vectors. Th...

In two studies we investigated whether concept mapping or summary writing better support students while learning from authentic problems in the field of business. We interpret concept mapping and summary writing as elaboration tools aiming at helping students to understand new information, and to integrate it with prior knowledge. We hypothesize concept mapping to be superior to summary writing...

The performance of speech communication channels featuring long delay times is usually subjectively experienced as lower than similar channels without delay. Yet most conventional speech intelligibility and speech quality tests are not sensitive to the effects of delay. Moreover, these conventional test do not take the effects of human compensating strategies into account, which help cope with ...

At The Hong Kong Polytechnic University, a two-credit gene ral education course entitled “ Tomorrow ’ s Leaders ” was developed to promote intraand interpersonal competencies in university students. The course was piloted in four classes of students in the 2010/11 academic year. Pre-test and posttest data utilizing the Chinese Positive Youth Development Scale (CPYDS) were collected from 50 stud...

The interplay between youth development staff and STEM (science, technology, engineering, and mathematics) professionals can influence girls’ interest in STEM careers. Build IT, an afterschool and summer youth-based curriculum for middle school girls, uses design, communication technologies, and structured interactions with IT professionals to encourage girls’ IT fluency, interest in mathematic...

Although an understanding of fractions is a critical precursor for other mathematical concepts, including proportional reasoning, algebra, and success in STEM fields, surveys of mathematics education in the United States indicate that school-age children lack age-appropriate math skills and proficiency. Thus, understanding the critical precursors of fraction knowledge is important for the devel...

New test design techniques should result in better coverage of the input domain and more efficient test cases. In this paper we propose a software-testing model for generating efficient test cases based on the special properties of Design of Experiments (DOE) and Logistic Regression. This model allows the software tester to design and generate efficient test sets. Also the proposed model provid...

The presented project is part of an ongoing PhD research project focused on the role of the sense of touch in interactive architectural environments. The aim is to explore how touch based interaction and stimuli can be applied in context of interactive architecture and what new design paradigms have to be developed. Based on the research through design approach [2], different tactile stimulatin...
