    Get PDF
    The proposed software guidelines to be followed by the European Space Research Organization in the development of software for the Spacelab being developed for use as a payload for the space shuttle are documented. Concepts, techniques, and tools needed to assure the success of a programming project are defined as they relate to operation of the data management subsystem, support of experiments and space applications, use with ground support equipment, and for integration testing

    Can Digital Drawing Tools Significantly Develop Children’s Artistic Ability and Creative Activity?

    Get PDF
    This study aims to investigate how the new digital art tools can significantly improve children‟s artistic ability and creative activity. This particular research tested 16 students aged 9-10 years old in art classes, with the intention of presenting a model for the development and measurement of technological creativity. It uses a modified TAM technology acceptance model to assess the usefulness of digital art tools. The children were provided with appropriate subjects and techniques to improve their performance with the tools, and the relationship between art, technology and creativity was explored. The results of the project show a general improvement in pupils‟ artistic ability and inventiveness through the development of their technological skills, as well as greater ability to express themselves visually

    Channel Choice Determinants; an exploration of the factors that determine the choice of a service channel in citizen initiated contacts

    Get PDF
    Citizens have various service channels at their disposal to interact with governmental agencies. In this paper we explore citizens’ motives to choose a certain channel in a certain situation. We conducted a qualitative study to accumulate the most important behavioral determinants. Six groups of determinants were found; habit, channel characteristics, task characteristics, situational constraints, experiences and personal characteristics. People appear to generally follow two lines of decision making when choosing channels, the first is based on habits. When task complexity and ambiguity increase, people start reasoning and follow the second line; channel choice based on a thorough elaboration between task and channel characteristics

    Development and implementation of the verification process for the shuttle avionics system

    Get PDF
    The background of the shuttle avionics system design and the unique drivers associated with the redundant digital multiplexed data processing system are examined. With flight software pervading to the lowest elements of the flight critical subsystems, it was necessary to identify a unique and orderly approach of verifying the system as flight ready for STS-1. The approach and implementation plan is discussed, and both technical problems and management issues are dealt with

    Testing mixed-signal cores: a practical oscillation-based test in an analog macrocell

    Get PDF
    A formal set of design decisions can aid in using oscillation-based test (OBT) for analog subsystems in SoCs. The goal is to offer designers testing options that do not have significant area overhead, performance degradation, or test time. This work shows that OBT is a potential candidate for IP providers to use in combination with functional test techniques. We have shown how to modify the basic concept of OBT to come up with a practical method. Using our approach, designers can use OBT to pave the way for future developments in SoC testing, and it is simple to extend this idea to BIST.European Union 2635

    What Drives Students' Loyalty-Formation in Social Media Learning Within a Personal Learning Environment Approach? The Moderating Role of Need for Cognition

    Get PDF
    Our study analyzes an educational experience based on the integrated use of social media within a higher education course under a personal learning environment approach and investigates the factors that determine students' loyalty to social media learning. We examined the moderating role of need for cognition (NFC) in students' formation of attitudes, satisfaction, and loyalty toward this learning experience. The results indicate that NFC has an influence on these variables, significantly moderating how loyalty toward social media learning is formed. For high-NFC students, satisfaction with the learning experience is the most important variable to explain loyalty; whereas for low-NFC students, attitudes have a stronger effect. Different strategies are suggested, according to the learners' NFC levels, for increasing the use of social media in personal learning environments. Practical implications for improving the integration of such informal resources into formal education are discussed.Junta de Andalucía – Programa Andaluz de I + D P12 SEJ 259

    Learning IoT without the "I" - Educational Internet of Things in a Developing Context

    Get PDF
    To provide better education to children from different socio-economic backgrounds, the Thai Government launched the "One Tablet PC Per Child" (OTPC) policy and distributed 800,000 tablet computers to first grade students across the country in 2012. This initiative is an opportunity to study how mobile learning and Internet of Things (IoT) technology can be designed for students in underprivileged areas of northern Thailand. In this position paper, we present a prototype, called OBSY (Observation Learning System) which targets primary science education. OBSY consists of i) a sensor device, developed with low-cost open source singled-board computer Raspberry Pi, housed in a 3D printed case, ii) a mobile device friendly graphical interface displaying visualisations of the sensor data, iii) a self-contained DIY Wi-Fi network which allows the system to operate in an environment with inadequate ICT infrastructure

    Are e-readers suitable tools for scholarly work?

    Full text link
    This paper aims to offer insights into the usability, acceptance and limitations of e-readers with regard to the specific requirements of scholarly text work. To fit into the academic workflow non-linear reading, bookmarking, commenting, extracting text or the integration of non-textual elements must be supported. A group of social science students were questioned about their experiences with electronic publications for study purposes. This same group executed several text-related tasks with the digitized material presented to them in two different file formats on four different e-readers. Their performances were subsequently evaluated by means of frequency analyses in detail. Findings - e-Publications have made advances in the academic world; however e-readers do not yet fit seamlessly into the established chain of scholarly text-processing focusing on how readers use material during and after reading. Our tests revealed major deficiencies in these techniques. With a small number of participants (n=26) qualitative insights can be obtained, not representative results. Further testing with participants from various disciplines and of varying academic status is required to arrive at more broadly applicable results. Practical implications - Our test results help to optimize file conversion routines for scholarly texts. We evaluated our data on the basis of descriptive statistics and abstained from any statistical significance test. The usability test of e-readers in a scientific context aligns with both studies on the prevalence of e-books in the sciences and technical test reports of portable reading devices. Still, it takes a distinctive angle in focusing on the characteristics and procedures of textual work in the social sciences and measures the usability of e-readers and file-features against these standards.Comment: 22 pages, 6 figures, accepted for publication in Online Information Revie
