A relatively simple architectural space was modeled and used to compare the effects of spatial training in simulations versus training in the real world. Thirty-five subjects were trained in one of the following conditions: real world (RW), virtual environment (VE), nonimmersive virtual environment (NVE), and model (Mod). The VE condition made use of a head-mounted display to view the simulated...

This article illustrates how the relationship between political geography and the electoral bias of a districting plan, as measured by the efficiency gap, can be analyzed in a statistically rigorous manner using computer simulations of the legislative redistricting process. By generating a large number of different districting plans designed to optimize on traditional redistricting criteria, th...

We have studied the performance of a high-speed commercial spread-spectrum wireless LAN that uses the CSMA/CA multiple-access strategy. Employing synthetic workloads, we measured packet capture success more so than signal propagation characteristics. Specifically , we measured throughput, packet loss rates, range, and patterns of errors within packets. We conclude that CSMA/CA is quite successf...

We present a new data structure for a set of n convex simply-shaped fat objects in the plane, and use it to obtain eecient and rather simple solutions to several problems including (i) vertical ray shooting | preprocess a set K of n non-intersecting convex simply-shaped at objects in 3-space, whose xy-projections are fat, for eecient vertical ray shooting queries, (ii) point enclosure | preproc...

BACKGROUND/OBJECTIVES Stroke is a leading cause of disability worldwide, and a significant proportion of stroke survivors require long-term institutional care. Understanding who cannot be discharged home is important for health and social care planning. Our aim was to establish predictive factors for discharge to institutional care after hospitalization for stroke. DESIGN We registered and co...

This note discusses the proposed plan for research on imaging and calibration algorithm development related to EVLA/ALMA. Attempt here is to describe briefly a work plan to address two problems which will need to be addressed in a few years from now, which also look tractable and towards which some work has already been done. In the sections below, the problems of continuum imaging with a bandw...

• In the quality control of a production process (of goods or services), from a statistical point of view, the focus is either on the process itself with application of Statistical Process Control or on its frontiers, with application of Acceptance Sampling (AS) and Experimental Design. AS is used to inspect either the process output (final product) or the process input (raw material). The purp...

After becoming operational in 2000, the first years of RHIC’s operation and analysis made a convincing case that the hot and dense QCD matter created at RHIC was strongly interacting and that its evolution could be described in hydrodynamic terms. By the time of the 2007 Long-Range Plan the field’s goals were shifting from qualitatively characterizing the matter created in heavy-ion collisions ...

O Plan is an AI planning architecture which supports research into a number of aspects of planning scheduling and control It is based on earlier work on the O Plan System which was directed towards plan generation The pa per explores the di erent types of choice or dering decisions which need to be made in an architecture for command and control The mechanisms for choice ordering and selection ...
