Title: Digital Earth: From a concept to high precision digital twins of the Earth
Abstract: Earth observation (EO) data – including satellite-borne, airborne or drone-based imagery - help to understand flows of rivers, how weather and climate conditions or to model future conditions and events. EO and Geoinformatics play a critical role in observing and understanding our environment and, ultimately, our lives. A metaphor and framework is the vision of “Digital Earth”. I will elucidate recent initiatives and conceptual frameworks for digital twins of the Earth. Such digital twins aim to create an interactive model of the Earth, which arises from the integration of individual models that accurately reflect diverse physical aspects of our planet and orchestrate reliable information about past, present, and future changes in the Earth system. The underlying models are based on measurements and observations while being complemented with state-of-the-art analytical techniques such as artificial intelligence (AI).

Speech Title: Challenges in the Next Generation IoT and Context-Active Resilience in Cyber Physical Systems
Abstract: Cyber-physical systems (CPS) refer to novel hardware and software compositions creating smart, autonomously acting devices, enabling efficient end-to-end workflows and new forms of user-machine interaction. A resilient CPS system is one that maintains state awareness and an accepted level of operational normalcy in response to disturbances, including threats of an unexpected and malicious nature. Due to its interdisciplinary and sophisticated nature, although resilience is critically desired in CPS, existing approaches and tools are only able to support limited resilience in a non-dynamic manner, i.e., fail to consider and respond to a comprehensive profile of the current states and needs of the devices and human users, which are always dynamically changing during the running of a CPS. We define such a profile as the context of a CPS, and advocate that a CPS should adapt itself actively and even proactively for the optimal functions and Quality of Services (QoS) according to this dynamic context. This is a new level of resilience, which has not been aimed at by previous work, and we define it as “Context-Active Resilience (CAR)”. We aim to develop a novel approach to context-active resilience in CPS, which ensures the best matching and optimal functions and QoS of the CPS in real-time during the running of the CPS.

Title: Study on Permeability and Micro-structures of Non-cement Blended Composites
Abstract: This study aimed to conduct in the mixture of non-cement blended materials using the combination of CFB co-fired fly ash and ground-granulated blast furnace slag without alkali activator. The effect of water/binder ratio, fly ash content and slag content on mechanical properties and microstructures has investigated. Test methods include flowability, compressive strength, absorption, non-steady-state chloride migration test, x-ray diffraction analysis (XRD) and scanning electron microscope observation were performed and analyzed. The results indicated that the compressive strength of non-cement fly ash/slag blended mortar is similar to that of ordinary Portland mortar. The specimens using 50% co-fired fly ash combined with 50% slag reflected completely hydration and had highest compressive strength up to 38 MPa as well as lower coefficient of chloride diffusion. XRD results expected that Ca(OH)2 reacted with SiO2 or Al2O3 to form C–S–H or C–A–S–H colloids, which was a major source of strength development in the non-cement blended materials. Being able to utilize industrial by-products in production of non-cement blended materials is significant in giving alternatives in the conservation of construction raw materials
Keywords: Co-Fired fly ash, ggbs, Non-Cement blended composites, Chloride diffusion coefficient.

Speech Title: Current Situation of global water system connectivity and its evaluation
Abstract. Assessments of total suspended substances (TSS) are important to environmental management and risk analysis of ecosystems. In this study, we discuss the developed process of a two bands TSS remote sensing model for water quality monitoring. The model has been validated by different remote sensing sensors, such as Landsat TM, MODIS. The model has been applied in estuaries and coasts of United States and China including water bodies with different turbidities. The application is also produced on evaluation of water quality effects on Chinese White Dolphin habitat in Pearl River Estuary and coral reef in southwest of Leizhou peninsula of south China.

Title: Hydrological investigation of bridge passages by using of remote Earth sounding.
Abstract: The thesis is relevant to a problem of use space shooting and airborne techniques for hydrological survey of bridge passages. There has been developed a new valid approach to hydrological survey of bridge passages, based on use of remote Earth sounding methods, which are accomplished from an artificial satellite, an airplane or another aircraft. The GIS of drain process have been elaborated using space information for the purpose of the overall estimation of surface run-off conditions, study drainage network and storage basins characteristics as well as impound flood-lands forecasting and prevention. The high trustworthiness of identification of objects, engineering constructions, drainage network elements and underflooding boundaries is reached at photointerpretation. The remote sounding from an airplane can be used successfully for determination of the calculated probabilistic values such as levels, water consumption, streams rates, stream jets directions, quantity and structure of solid material transferred by water flow, river-bed modification. The functional dependence for determination of the overall and local values of offshore motion of sediments, backwater etc. on basis of aerial photography has been developed by means of a bridge passage GIS. The schemes for realization of aerial hydrometric measurements have been elaborated.
Keywords: remote Earth sounding, hydrological survey, GIS of drain process, bridge passage GIS, GIS floods, GIS of regional flood risk assessment, GIS of local flood risk assessment.
