A hypertext version of this paper is also available 1]. This paper provides a brief description of a software tool developed within the tltp Interact Project 2] which allows application programs, concurrently executing within a Unix environment, to be controlled by scripts delivered to Mosaic from W3 servers. This tool was developed to allow the coupling of interactive simulations of sci-entiic...

We present techniques for realistic real-time rendering of complex landscapes that consist of many highly detailed plant models. The plants are approximated by dynamically changing sets of billboards. Realistic illumination is approximated using spherical harmonics. Since even the rendering of simple billboard cloud plants is too time consuming, the landscape in the background is approximated w...

Transit IP internetworks supporting USAF bases are highly congested during duty-hours and attempts to access to the Internet often fail. Often, during these connection failures, transit networks are in a state known as congestion collapse and connections time out when a user attempts to reach the Internet. This paper presents the results of a simple IP congestion analysis between four USAF base...

We are given a set of video clips, each one annotated with an ordered list of actions, such as “walk” then “sit” then “answer phone” extracted from, for example, the associated text script. We seek to temporally localize the individual actions in each clip as well as to learn a discriminative classifier for each action. We formulate the problem as a weakly supervised temporal assignment with or...

Hypothetical bias is one of the main issues bedeviling the field of nonmarket valuation. The general criticism is that survey responses reflect how people would like to behave, rather than how they actually behave. In our study of climate change and emissions reductions, we took advantage of the increasing bulk of evidence from psychology and economics that addresses the effects of making promi...

Generally speaking, Electronic Book can be defined as a multimedia software product synthesizing multimedia such as text, voice, audio effect, image, animation and video into a scenario where interaction can be made with the readers during the acting process. An e-book is composed of 3 parts: (1)programming design; (2)script design; (3)art and audio effect design. Producing an e-book is quite l...

Determination of script type of document image is a complex real life problem for a multi-script country like India, where 23 official languages (including English) are present and 13 different scripts are used to write them. Including English and Roman those count become 23 and 13 respectively. The problem becomes more challenging when handwritten documents are considered. In this paper an app...

AutoTutor is a learning environment that tutors students by holding a conversation in natural language. AutoTutor has been developed for Newtonian qualitative physics and computer literacy. Its design was inspired by explanation-based constructivist theories of learning, intelligent tutoring systems that adaptively respond to student knowledge, and empirical research on dialogue patterns in tut...

We present a novel Evaluation Metric for Morphological Analysis (EMMA) that is both linguistically appealing and empirically sound. EMMA uses a graphbased assignment algorithm, optimized via integer linear programming, to match morphemes of predicted word analyses to the analyses of a morphologically rich answer key. This is necessary especially for unsupervised morphology analysis systems whic...
