Abstract We propose a novel robotic system that combines both a reliable programming-based approach and a highly generalizable learning-based approach. How to design and implement a series of tasks in an atypical environment is a challenging issue. If all tasks are implemented using a programming-based approach, the development costs will be huge. However, if a learning-based approach is used, reliability is an issue. In this paper, we propose novel design guidelines that focus on the respective advantages of programming-based and learning-based approaches and select them so that they complement each other. We use a program-based approach for actions that are dynamic and require safety and reliability and a learning-based approach for actions that have a limited working area and are difficult to achieve with a program. Our learning approach can easily and rapidly accomplish a series of tasks consisting of various motions because it does not require a computational model of an object to be designed in advance. We demonstrate a series of tasks in which randomly arranged parts are assembled using an actual robot.

Distance Learning Environment

This research is a theory building study regarding the design of distance learning environments from a socio-technical perspective. Within this study, a synthesis of current theories and approaches in addition to established theories in the field of distance education will be conducted, with focus placed on the notion that a flexible learning environment may be designed based on social and technical elements. In this regard, the process of designing the aforementioned learning environment is expressed in a theoretical manner, with the following two theories comprising the basis of the study: (1) the Flexible Learning Approach and (2) the Socio-Technical Theory. A theoretical matrix is established within the study utilizing these theories, while each cell in the theoretical matrix provides a statement that determines a flow chart regarding the design of Flexible Distance Learning Environments.

Abstract Island-bridge structures incorporated with kirigami membranes emerge as a novel design strategy for flexible/stretchable electronics, taking advantages of large stretchability, high-surface filling ratio and low resistance. However, it is hard to determine the mechanical properties of this design due to its complex geometries and nonlinear deformation configuration, thereby limiting its further applications. In this paper, we present a model for the postbuckling behavior of kirigami membranes through a combination of theoretical modeling, finite element analysis, and experiments. Scaling laws for elastic stretchability are developed, showing good agreement with numerical results and experimental images. Investigations on the critical height of post array are conducted to ensure the boundary condition of the kirigami membranes in the analytical model. These results can serve as design guidelines for kirigami structures and facilitate their applications in flexible/stretchable electronics.

Simulating battle management is an essential technique used in planning and mission rehearsal as well as training. Simulation development costs tend to be high due to the complexity of cognitive system architectures in such applications. Due to this complexity, it takes significant effort for a simulation developer to comprehend the problem domain enough to capture accurately in a simulation code. Domain-specific languages (DSL) play an important role in narrowing the communication gap between the domain user and the developer and hence facilitate rapid development. In command and control (C2) applications, the coalition battle management language (C-BML) serves as a DSL for exchanging battle information among C2 systems, simulations, and autonomous elements. In this article, we use a rapid prototyping framework for cognitive agents and demonstrate deployment of agent systems by adopting the model driven engineering approach. To this end, we extend the use of C-BML and automatically transform it in a cognitive agent model, which is then used for adaptive decision making at runtime. As a result, during a simulation run, it is possible to initialize and modify an agent’s goal reasoning model. The cognitive agent models are based on the deliberative coherence theory, which provides a goal reasoning system in terms of coherence-driven agents.

Fluid Interaction

The on-bottom stability design of subsea pipelines is important to ensure safety and reliability but is challenging to achieve, particularly in Australia due to onerous metocean and seabed conditions, and the prevalence of light gas pipelines. This challenge has been amplified by the fact that industry design guidelines have given no guidance on how to incorporate the potential benefits of seabed mobility, which can lead to lowering and self-burial of the pipeline on a sandy seabed. In this paper, we review the learnings of the STABLEpipe Joint Industry Project (JIP), which was initiated with the aim of developing new design guidelines to assess the on-bottom stability of pipelines on mobile seabeds. The paper summarises the new research undertaken within the STABLEpipe JIP to better predict sedimentation and scour, pipe-fluid interaction and pipe-soil interaction. New design methods to assess the on-bottom stability are also outlined, which have been developed based on the new research. These methods have been adopted in a DNVGL guideline authored by the JIP researchers in collaboration with DNVGL and presently available for use by the JIP participants. Finally, applications of the STABLEpipe JIP outcomes and focus areas for further work are discussed.

Shell has developed a new approach to the commercialisation of remote offshore natural gas assets. Floating LNG (FLNG) has the potential to change the face of LNG production and supply in the future and offer customers the opportunity to access an even wider scope of natural gas resources in the 21st Century.FLNG combines two simple, proven and reliable technologies: Floating Production, Storage and Offloading systems (FPSO) which are widely used in the oil industry, and LNG manufacturing, logistics and transportation. This paper describes progress by Shell, together with its Alliance partner Woodside, in applying its FLNG technology in northern Australia.The FLNG concept offers significant reductions in development costs across the supply chain, removing the need for offshore trunklines and combining platform and processing together with LNG production, storage and loading. FLNG also offers attractive opportunities for production of smaller tranches of LNG at a cost that can be competitive with brownfield expansion of onshore facilities.On the technical side, there has been practical field experience with almost all of the individual elements of an FLNG facility. Furthermore, Shell has carried out extensive engineering and design work on the integration of these elements to ensure that FLNG offers customers the same safety and reliability as from an onshore plant.With the combined advantages of market proximity, proven reliability, strong relationships with established and emerging customers, a politically stable environment and strong government support, Australia offers an exciting opportunity for the development and first deployment of FLNG.
