Refined modeling of heterogeneous medium for ground-penetrating radar simulation
No full textGround-penetrating radar (GPR) has been widely used for subsurface detection and testing. Numerical simulations of GPR signal are commonly performed to aid the interpretation of subsurface structures and targets in complex environments. To enhance the accuracy of GPR simulations on heterogeneous medium, this paper proposes a hybrid modeling method that combines the discrete element method with a component fusion strategy (DEM–CFS). Taking the asphalt pavement as an example, three 3D stochastic models with distinctly different porosities are constructed by the DEM–CFS method. Firstly, the DEM is utilized to establish the spatial distribution of random coarse aggregates. Then, the component fusion strategy is employed to integrate other components into the coarse aggregate skeleton. Finally, the GPR response of the constructed asphalt models is simulated using the finite-difference time-domain method. The proposed modeling method is validated through both numerical and laboratory experiments and demonstrates high precision. The results indicate that the proposed modeling method has high accuracy in predicting the dielectric constant of heterogeneous media, as generated models are closely aligned with real-world conditions
From relationships and community to risk and compliance : reflections on fifty years of protecting children
No full textTrials and tribulations in perfecting student collaboration and teamwork
No full textCollaboration and teamwork are regarded as essential skills for students to develop in order to succeed in the modern workplace. They are ubiquitously listed as one of the key graduate attributes to develop and approaches to the development of teams are expected
by Professional, Statutory, and Regulatory Bodies (PSRBs). However, perfecting, teaching, and assessing these skills giving weight and wider context can be challenging along with convincing students of their value. This presentation will explore a ten-year journey into the trials and tribulations in attempting to replicate and test many of the
available examples to perfecting student collaboration and teamwork
The Time House : between cybernetics and phenomenology
No full textMartin Pawley’s ‘The Time House’ (1968) is a study on how to use multimedia technologies to provide a continuous record of individual experience within the domestic interior. The project’s underlying argument is that there is no authentic experience to be had in the public realm. As an antidote, Pawley proposes a retreat into a private world, where individuals, with the use of technology, can retain a continuous and repayable record of time. Thus, The Time House would enable its inhabitants to relive – phenomenologically, with all the senses – past experiences. Pawley believed that this repeated, unembellished re-creation of the past would reveal to its inhabitants a truer version of both the past and themselves, thus offering opportunities for introspection and self-knowledge. The Time House tries to bring together all the key concerns of architecture in the late 1960s: cybernetics, phenomenology, environmental behaviour studies, the use of cutting-edge technology, Cold War politics and fears, and the countercultural aim to expand human consciousness. Yet, Pawley’s proposition to use technology to simulate lived experiences with the aim of altering human behaviour still stimulates heated arguments today. These arguments stem from current fears about the effects of digital technologies on individuals and society: the disconnection with the here-and-now, the prioritisation of the individual over the collective, the disintegration of reality and the neglect of social public space. The Time House, which could be dismissed as a project of its time and place, is embedded in a web of ideas still resonant in our present
