This paper presents an experiment comparing the relative impact of different types of degradation on subjective quality ratings of interactive speech transmitted over packet-switched networks. The experiment was inspired by observations made during a large-scale, long-term field trial of multicast conferencing. We observed that user reports of unsatisfactory speech quality were rarely due to network effects such as packet loss and jitter. A subsequent analysis of conference recordings found that in most cases, the impairment was caused by end-system hardware, equipment setup or user behavior. The results from the experiment confirm that the effects of volume differences, echo and bad microphones are rated worse than the level of packet loss most users are likely to experience on the Internet today, provided that a simple repair mechanism is used. Consequently, anyone designing or deploying network speech applications and services ought to consider the addition of diagnostics and tutorials to ensure acceptable speech quality.

Terminal access to computer systems has long been and continues to be a problem of major significance. We foresee an increasing demand for access to data processing and storage facilities from interactive terminals, point-of-sales terminals, real-time monitoring terminals, hand-held personal terminals, etc. What is it that distinguishes this problem from other data communication problems? It is simply that these terminals tend to generate demands at a very low duty cycle and are basically bursty sources of data; in addition, these terminals are often geographically distributed. In the computer-to-computer data transmission case, one often sees high utilization of the communication channels; this is just not the case with terminal traffic. Consequently, the cost of providing a dedicated channel to each terminal is often prohibitive. Instead, one seeks ways to merge the traffic from many terminal sources in a way which allows them to share the capacity of one or a few channels, thereby reducing the total cost. This cost savings comes about for two reasons: first, because of the economies of scale present in the communications tariff structure; and secondly, because of the averaging effect of large populations which permit one to provide a channel whose capacity is approximately equal to the sum of the average demands of the population, rather than equal to the sum of the peak demands (i.e., the law of large numbers). This merging of traffic and sharing of capacity has been accomplished in various ways such as: polling techniques, contention systems, multiplexing, concentrating, etc. Many of these are only weak solutions to the problem of gathering low data rate traffic from sources which are geographically dispersed.
The age-old practice of cartography has undergone funda- mental shifts with the advent of the digital age. Today's digital maps are often crowd-sourced, allow interactive route planning, and may contain live updat...

With the growth of organic Fruits and Vegetables (FaVs) markets, there is now a trend in marketing research toward studies of non-standardized fruits and vegetables in stores. Yet, because of the decaying nature of FaVs, it is difficult to conduct such studies. A solution is to conduct them within a Virtual Environment (VE) (with virtual FaVs). Therefore, it is of interest to develop an approach to generate a large variety and variability of FaVs, so one can later use them in a VE. In this paper we introduce a pipeline to generate a large variability of FaVs, focusing both on their shape and on their external appearance. Regarding the shape, we use a semi-automated approach. A parametric Skeletal Structure and Generalized Cylinders (GCs) generates their overall shape and metaball-based techniques give them an organic aspect. Regarding their external appearance, we use a particle system approach to simulate their modifications over time. This particle system-based approach decomposes FaVs appearance changes into distinct visual characteristics producing different texture maps that can be combined.

Existing computer algebra systems relieve us of having to perform tedious mathematical computations manually, thus enabling us to gain insight on the abstract problems at hand. Often these systems suggest alternate solution techniques directly. However, existing systems do little to help us manage the interactive computing environment as the scale of the problem grows: when the number of mathematical objects being studied increases, the complexity for a user to manage those objects in his environment seems to grow disproportionately. We need tools to relieve us of tedious organizational overhead every bit as much as we need the mathematical tools *** response to this need, we are constructing a management assistant that works in conjunction with existing symbolic computation systems. Called Minion, it allows users to express simple plans for solving large problems in the interactive environment, and then guides the user's interaction according to that plan. Key features of this assistant are that plans are easy to construct (whether statically or during the problem solving session); the assistant helps a user visualize progress towards solving the global problem; and individual steps within a plan can be executed by arbitrary software tools, whether symbolic-, numeric- or logic-based in their *** prototype of Minion is made possible by the Polylith software interconnection system [Purt85, Purt88]. Previously we showed how Polylith's general software tool-bus based organization could help overcome the so-called 'symbolic-numeric gap' [Purt86]. Our current work with Minion takes advantage of that interconnection technology in order to focus on the management problems inherent within large scale, mathematical problem solving *** paper briefly portrays the organizational problem that must be treated, and motivates the need for structure management tools in mathematical problem solving environments. We detail features of our Minion proto

This paper evaluates different state-of-the-art approaches for implementing an X-ray view in Augmented Reality (AR). Our focus is on approaches supporting a better scene understanding and in particular a better sense of depth order between physical objects and digital objects. One of the main goals of this work is to provide effective X-ray visualization techniques that work in unprepared outdoor environments. In order to achieve this goal, we focus on methods that automatically extract depth cues from video images. The extracted depth cues are combined in ghosting maps that are used to assign each video image pixel a transparency value to control the overlay in the AR view. Within our study, we analyze three different types of ghosting maps, 1) alpha-blending which uses a uniform alpha value within the ghosting map, 2) edge-based ghosting which is based on edge extraction and 3) image-based ghosting which incorporates perceptual grouping, saliency information, edges and texture details. Our study results demonstrate that the latter technique helps the user to understand the subsurface location of virtual objects better than using alpha-blending or the edge-based ghosting.
