12 Jun 2017TL;DR: This work investigates how the immediate control of computer numerical control (CNC) machines can narrow the design-fabrication gap and combine manual art practice with digital fabrication.
Abstract: We investigate how the immediate control of computer numerical control (CNC) machines can narrow the design-fabrication gap and combine manual art practice with digital fabrication. LINC (Live Interactive Numeric Control) is a sketch-based digital design tool for authoring 2D or 3D artworks in near-real time. To use LINC, users draw strokes which are then executed in one of three modes---static, manual, or as soon as possible---by either a large-scale or desktop-sized modified CNC router. We evaluate LINC through a study with eight artists.

TL;DR: In this article, the authors present a design tool and method which creates a VHSIC Hardware Description Language (VHDL) board model that can be used by digital engineers to verify their ASIC and FPGA designs.
Abstract: The present invention provides a design tool and method which creates a VHSIC Hardware Description Language (VHDL) board model that can be used by digital engineers to verify their ASIC and FPGA designs. (VHSIC is an acronym for Very High Speed Integrated Circuits.) The board model is used as part of the test bench that tests the functionality of the board. Any models of the component parts can be instantiated in the board model using a “configuration” statement in the VHDL. Any inconsistencies between the board requirements and the ASIC and FPGA specifications can be identified.

06 Mar 2004TL;DR: The goals and status of MBED are reviewed, the expected interconnectivity between conceptual and detailed design is shown, and current capability for rapid conceptual design is extended.
Abstract: The basic elements of model-based design for space missions have existed for almost a decade, awaiting an opportunity to implement them in the same place at the same time. In early design phases, combinations of models, concurrent engineering methods, and scenario-driven design have been used for several years with results that have exceeded even optimistic expectations; but the goal of extending these methods to later phases of design has been more elusive. JPL's model-based engineering design (MBED) initiative provides opportunity to reach that goal. It enables advanced systems engineering practice through a series of integrated, increasingly detailed models that provide continuity from architectural concept through detailed design. It extends current capability for rapid conceptual design, allowing thorough exploration of design tradespaces and selection of an optimal design point with associated cost and rationale; and it provides seamless connection to subsystem models and detailed design tool suites. We review the goals and status of MBED and show the expected interconnectivity between conceptual and detailed design.

TL;DR: The ENERGY-10 program overcomes many of the time-consuming tasks, shortening the time required from hours or days to minutes, and planned enhancements including a capability for photovoltaics simulation are outlined.
Abstract: A major barrier to using energy simulation tools during the design process of a building has been the difficulty of using the available programs. The ENERGY-10 program overcomes this hurdle by automating many of the time-consuming tasks, shortening the time required from hours or days to minutes. Building descriptions are created automatically based on defaults. The APPLY and RANK features speed the process of comparing the performance of energy-efficient strategies by automatically modifying the building description and sequencing the operations. Graphical output greatly aids the process of assimilating and understanding the results. This paper describes the program’s features, simulation engines, the associated design guidelines book, and the workshop training program. It also outlines planned enhancements including a capability for photovoltaics simulation, and the steps required to make the program useful outside the United States.

01 Nov 2018TL;DR: This work demonstrates how the application of reachability analysis to a dynamic model of a stormwater network can characterize the set of initial conditions from which every element in the network can avoid overflowing under a given surface runoff signal of finite duration.
Abstract: Effective stormwater management requires systems that operate safely and deliver improved environmental outcomes in a cost-effective manner. However, current design practices typically evaluate performance assuming that a given system starts empty and operates independently from nearby stormwater infrastructure. There is a conspicuous need for more realistic design-phase indicators of performance that consider a larger set of initial conditions and the effects of coupled dynamics. To this end, we apply a control-theoretic method, called reachability analysis, to produce a more objective measure of system robustness. We seek two primary contributions in this work. First, we demonstrate how the application of reachability analysis to a dynamic model of a stormwater network can characterize the set of initial conditions from which every element in the network can avoid overflowing under a given surface runoff signal of finite duration. This is, to the authors’ knowledge, the first published application of reachability analysis to stormwater systems. Our second contribution is to offer an interpretation of the outcomes of the proposed reachability analysis as a measure of system robustness that can provide useful information when making critical design decisions. We illustrate the effectiveness of this method in revealing the trade-offs of particular design choices relative to a desired level of robustness.
