AbstractInformation technologies are a driving force for progress in the design field, allowing new modes of creativity. However, most of the existing computational design tools are focused on the latest stages of the design process and especially directed to drafting operations. Conceptual design tools that support the designer in the creative and inventive early stages of the design project are still in their early development. Shape grammars (SG) were introduced by George Stiny in the 1970s, allowing the generation of designs according to a set of predefined rules. SG computational implementations have the potential to answer the need for tools that can assist designers, architects, and artists in the creative process, offering design alternatives, stimulating new ideas and encouraging the search for new design generation processes. Acknowledging this potential, a user-friendly interface seems essential for the adoption of these tools. Taking Scott Chase's interaction model as background, the aim of the present investigation is to define guidelines and begin to design a graphical-user interface for SG implementations. Inspection methods of human–computer interaction (HCI) were used to analyze existing SG implementations and understand usability issues. Subsequently, HCI ergonomic criteria for interface evaluation were adapted to establish guidelines for the design of an SG implementation interface, called IM-sqi. These guidelines take into account different user groups, adjustable interaction modes for each user group, and the nature of each task performed by the user.

This paper builds on previous concept generation techniques explored at the University of Missouri - Rolla and presents an interactive concept generation tool aimed specifically at the early concept generation phase of the design process. Research into automated concept generation design theories led to the creation of two distinct design tools: an automated morphological search that presents a designer with a static matrix of solutions that solve the desired input functionality and a computational concept generation algorithm that presents a designer with a static list of compatible component chains that solve the desired input functionality. The merger of both the automated morphological matrix and concept generation algorithm yields an interactive concept generator that allows the user to select specific solution components while receiving instantaneous feedback on component compatibility. The research presented evaluates the conceptual results from the hybrid morphological matrix approach and compares interactively constructed solutions to those returned by the non-interactive automated morphological matrix generator using a dog food sample packet counter as a case study.

In combustion chemistry experiments, reaction rates are often extracted from complex experiments using detailed models. To aid in this process, experiments are performed such that measurable quantities, such as species concentrations, flame speed, and ignition delay, are sensitive to reaction rates of interest. In this work, a systematic method for determining such sensitized experimental conditions is demonstrated. An open-source python script was created using the Cantera module to simulate thousands of 0D and hundreds of 1D combustion chemistry experiments in parallel across a broad, user-defined range of mixture conditions. The results of the simulation are post-processed to normalize and compare sensitivity values among reactions and across initial conditions for time-varying and steady-state simulations, in order to determine the “most useful” experimental conditions. This software can be utilized by researchers as a fast, user-friendly screening tool to determine the thermodynamic and mixture parameters for an experimental campaign. We demonstrate this software through two case studies comparing results of the 0D script against a shock tube experiment and results of the 1D script against a spherical flame experiment. In the shock tube case study we present mixture conditions compared to those used in the literature to study H + O2 (+M)→HO2(+M). In the flame case study, we present mixture conditions compared to those in the literature to study formyl radical (HCO) decomposition and oxidation reactions. The systematically determined experimental conditions identified in the present work are similar to the conditions chosen in the literature.

Along with the shift from print to digital formats, information technologies are significantly affecting today’s libraries. New technologies and concepts such as mobile devices, social networking sites, communication and interactive tools, and other Internet technologies are changing how libraries serve their patrons as well as how users interact with libraries and each other. Each technology has impacted the library user and the user environment so much so that today’s library is said to be everywhere. Wherever the user can go with their mobile device and access the Internet, and therefore the library OPAC, it can functionally be said that they are at the library, for the collection, user services, and library databases is where the library is located, not the brick and mortar structure. This increased access also raises concerns over online information security and privacy, and the conscious Internet user needs to be aware of the dangers and take the necessary steps to mitigate them. The concept of change is another element of these new information technologies—embracing it, for technology is always changing as new ideas spark new revolutions in development and libraries must change along with them. All information institutions must learn to ride these waves of change instead of being pulled along, half drowning, by the undertow. Learning to both integrate and inform patrons on how best to use these technologies becomes an important part of being an information expert. Surveyed in this chapter is a selection of those important and driving technologies and changes.

The Common

This chapter provides a background to the common “linguistic” analogies in architectural thinking, which are concerned with the “grammar” of form and the “syntax” of space. The chapter then links these linguistic properties to the classical Vitruvian architectural values of firmness, commodity, and delight. Thereafter, the chapter introduces the two most well-known computational design approaches, Shape Grammar and Space Syntax, and briefly outlines the general applications of each. In addition, throughout this book, new grammatical and syntactical approaches are typically demonstrated using the domestic architecture of Andrea Palladio, Frank Lloyd Wright, and Glenn Murcutt. Thus, this chapter also introduces these three architects and their architectural languages.
