TL;DR: In this paper, the authors summarise the results of a 3-year research project by the CRC for Catchment Hydrology (CRCCH) on the joint probability approach (Monte Carlo simulation technique) to design flood estimation and the subsequent research activities to further the CRCCH method towards industrial applications.
Abstract: This paper summarises the results of a 3-year research project by the CRC for Catchment Hydrology (CRCCH) on the joint probability approach (Monte Carlo simulation technique) to design flood estimation and the subsequent research activities to further the CRCCH method towards industrial applications. It identifies significant shortcomings in the current design event approach to rainfall-based design flood estimation, and argues that substantial improvements in the accuracy and reliability of flood estimates can be obtained from a more rigorous treatment of probability aspects in the generation of design floods. Applications of the proposed Monte Carlo simulation approach to test catchments in Victoria and Queensland have produced promising results, and demonstrated the feasibility and in-principle advantages of the approach. More recently, the Monte Carlo simulation approach has been integrated with the industry-based flood estimation model URBS thus significantly broadening its range of application. The paper discusses how far the recent research on the joint probability approach has advanced towards resolving the main research issues, and outlines desirable future development work to allow the new method to be routinely applied as a design tool.

TL;DR: In this paper, the authors used past accident knowledge as a basis to develop a safety oriented design tool whereby the accident information were directly disseminated into plant design, which can detect up to 74% of design errors.

TL;DR: In this article, a set of realistic test cases that provide load demand dynamics based on a variety of unique scenarios, mission load characteristics, and human-in-the-loop decision-making are introduced.
Abstract: The design and control of electric warship power systems is a complex, challenging problem and numerous power system architectures, technologies, algorithms, and control schemes have been proposed. Instead of a quantitative assessment of these ideas based on ideal, steady-state conditions, a set of representative operational vignettes that span the entire electric warship mission package is introduced in order to obtain true results. This paper describes a set of realistic test cases that provide load demand dynamics based on a variety of unique scenarios, mission load characteristics, and human-in-the-loop decision-making. Stochastic and deterministic power profiles are established for individual ship systems and mission loads, which are then combined together for a particular scenario. These test cases can be applied to early-stage design trade studies as well as design tool development. For example, various control methods can be benchmarked against the same test cases. In addition to the established test cases, the method used here enables operators to communicate to design engineers how they intend to use the ship (not the other way around).

TL;DR: A tool enabling nonprofessionals to create digital layouts for large-scale graphical virtual environments based on elements of the city image as described by the urban planner, Kevin Lynch (1960) is described.
Abstract: We describe a tool enabling nonprofessionals to create digital layouts for large-scale graphical virtual environments. The design tool is based on “elements of the city image” as described by the urban planner, Kevin Lynch (1960). These elements serve as both organizational principle and navigational aid. Further work is needed to situate the tool within a virtual environment so that output from the tool is transformed as extensions to the virtual world. Here we describe the theoretical basis for the tool, implementation of an initial prototype that illustrates a virtual world through a series of composited frames, and next-step revisions stemming from users' experiences with the prototype.

TL;DR: This paper explores the feasibility of executing a water-to-air transition with a fixed-wing vehicle using almost entirely commercial off-the-shelf components (excluding the fuselage) and proposes a conceptual design based on observations about the dominant forces and dimensionless analysis.
Abstract: In this paper, we describe the design and analysis of a fixed-wing unmanned aerial-aquatic vehicle. Inspired by prior work in aerobatic post-stall maneuvers for fixed-wing vehicles [1], we explore the feasibility of executing a water-to-air transition with a fixed-wing vehicle using almost entirely commercial off-the-shelf components (excluding the fuselage). To do this, we first propose a conceptual design based on observations about the dominant forces and dimensionless analysis. We then further refine this concept by building a design tool based on simplified models to explore the design space. To verify the results of the design tool, we use a higher fidelity model along with a direct hybrid trajectory optimization approach to show via numerical simulation that the water-to-air transition is feasible. Finally, we successfully test our design experimentally by hand-piloting a prototype vehicle through the water-to-air transition and discuss our approach for replacing the human-pilot with closed-loop control.
