  • Determination of carbonate rock chemistry using laboratory - based hyperspectral imagery

    • Authors: Zaini, Nasrullah;  Advisor: -;  Participants: - (2014)

  • The development of advanced laboratory-based imaging hyperspectral sensors, such as SisuCHEMA, has created an opportunity to extract compositional information of mineral mixtures from spectral images. Determining proportions of minerals on rock surfaces based on spectral signature is a challenging approach due to naturally-occurring minerals that exist in the form of intimate mixtures, and grain size variations. This study demonstrates the application of SisuCHEMA hyperspectral data to determine mineral components in hand specimens of carbonate rocks. Here, we applied wavelength position, spectral angle mapper (SAM) and linear spectral unmixing (LSU) approaches to estimate the chemical composition and the relative abundance of carbonate minerals on the rock surfaces. The accuracy of...

  • Global Information Society Watch :Communications surveillance in the digital age

    • Authors: -;  Advisor: -;  Participants: - (2014)

  • As the reports show, both states and businesses are complicit in communications surveillance. While there is a need for systems to monitor and protect the public from harm, the right to privacy, the transparency and accountability of states and businesses, and citizen oversight of any surveillance system are important advocacy concerns. These 13 Principles are an important starting point for civil society to achieve this collective action – to push action for democratic oversight of surveillance.

  • A sense of change :media designers and artists communicating about complexity in social - ecological systems

    • Authors: Vervoort, Joost M.;  Advisor: -;  Participants: - (2014)

  • To take on the current and future challenges of global environmental change, fostering a widespread societal understanding of and engagement with the complex dynamics that characterize interacting human and natural systems is essential. Current science communication methods struggle with a number of specific challenges associated with communicating about complex systems. In this study we report on two collaborative processes, a short workshop and longer course, that aimed to harness the insights of interactive media designers and artists to overcome these challenges. The two processes resulted in 86 new interactive media concepts which were selected by the participants and organizers using set criteria and then evaluated using the same criteria by a panel of communication and media ...

  • A Share Learning Framework for Innovation Education: Improving Creative Thinking Capability from Daily Life

    • Authors: Alex, R.; Yu, Z.;  Advisor: -;  Participants: - (2014)

  • Innovation has been widely recognized as a major driving force behind economic growth. Sharing thoughts is one of the most important steps of learning for innovation education. This paper aims to propose a share learning framework for innovation education. The activities in the share learning framework include problems sharing, knowledge sharing, methods sharing, solutions sharing and spirits sharing. A ten-step sharing process like Plan-Do-Check-Action stages is presented Then the main benefits for students and the barriers of sharing are discussed based on a ca e study of Creative Thinking course.

  • Assessing the quality land administration system in Pakistan using systematic approach of case study methodology

    • Authors: Ali, Zahir;  Advisor: -;  Participants: - (2014)

  • Land Information System is a tool for legal, administrative and economic decision making as well as an aid for planning and development. The present land administration system in Pakistan is entirely based on paper land records and maps lacking standards with outdated information stored at different administrative levels. Such practice restricts the usefulness of reliable and quality land information for supporting tenure security to citizens, socio-economic development, and urban/rural development including infrastructure. This situation demands for a methodological framework to assess the quality of the existing system before going to take necessary action for quality improvement. There have been a few efforts to standardize the procedures for assessing the quality of land adminis...

  • Carbon in dryland soils :multiple essential functions

    • Authors: Tiphaine, C.;  Advisor: -;  Participants: - (2014)

  • Soil organic carbon (SOC) has a key role in the overall behaviour of soils and agroecosystems. Increasing its content enhances soil quality and fertility, thus improving agricultural resilience and sustainability and, in turn, food security of societies. Soils also contain the largest pool of carbon interacting with the atmosphere. Agricultural and forestry systems that reduce atmospheric carbon concentrations by sequestering this carbon in biomass and in soil organic matter are carbon sinks. Combating desertification contributes to soil carbon sequestration, thus mitigating global warming, while contributing to sustainable agricultural management. Soils have only recently become a global environmental issue, especially in the framework of three international environmental conventio...
