An experiment investigated the assumption that natural indicators which exploit existing learned associations between a signal and an event make more effective warnings than previously unlearned symbolic indicators. Signal modality (visual, auditory) and task demand (low, high) were also manipulated. Warning effectiveness was indexed by accuracy and reaction time (RT) recorded during training a...

The management of storage — allocation and garbage collection — is intended to be transparent to the programmer and user, placing the burden on the implementation. In most situations, the Icon programmer does not need to think about the allocation of storage or its consequences on program performance. Nonetheless, in cases where the amount of memory is limited or where programs require unusuall...

Execution monitors are widely used during software development for tasks that require an understanding of program behavior, such as debugging and profiling. The Icon programming language has been enhanced with a framework that supports execution monitoring. Under the enhanced translator and interpreter, neither source modification nor any special compiler command-line option is required in orde...

– 1 – December 28, 1992 Icon workshops provide an opportunity for persons with an involvement in Icon to meet and discuss their mutual interests. The first two workshops were held in Flagstaff, Arizona in 1988 and 1990. The third workshop was held on September 10-11, 1992, in La Jolla, California. The workshop was sponsored by the Department of Computer Science and Engineering of the University...

The combination of map displays with icon techniques is well-suited for visualizing geospatial dependent multivariate data. The requirements for icon placement on the map, although not trivial, are not properly attended by most interactive visualization systems. In cartography, a number of methods for automatic text label placement and map generalization has been developed. These are focused on...

The single-column mode (SCM) of the ICON (ICOsahedral Nonhydrostatic) modeling framework is presented. primary purpose SCM to use it as a tool for research, model evaluation and development. Thanks simplified geometry SCM, various aspects model, in particular physics, can be studied well-controlled environment. Additionally, has reduced computational cost low data storage demand. utilized ideal...

Iconic memory is operationally defined by part-report experiments (Sperling, 1960). If a mask is presented after the target, the mask is thought to be superposed on the target in the iconic representation, or to displace it from the representation. But could a cue presented after a pattern mask still allow selection within the target array? A target array of letters was followed by a checkerboa...
