Tone and intonation share the common feature of being carried mainly by the fundamental frequency of voice (F0). The ease of obtaining F0 measurements, thanks to the wide availability of software tools and the fact that F0 is largely one-dimensional, have allowed researchers to perform extensive studies on tone and intonation. But ease of observation does not necessarily mean ease of understand...

Liquid foams have important practical applications in mineral separation and oil recovery. However, the details of the foam mechanics in these applications are poorly understood. Foam scientists have used 2D foam simulations to model foam behavior and 2D visualization solutions have helped them explore and analyze their data. Three-dimensional foam simulations remove some of the simplifying ass...

One resource playing a critical role in electronically supported decision-making groups is the facilitator. Facilitation is a complex task, encompassing social abilities, pre-meeting planning of decision-making processes and supervising the technology usage during meetings. We found two problems with previous support to electronic facilitation: (1) limited support to planning activities; and (2...

Building virtual humans is a task of formidable complexity. We believe that, especially when building agents that interact with biological humans in real-time over multiple sensorial channels, graphical, data flow oriented programming environments are the development tool of choice. In this paper, we describe a toolbox for the system control and block diagramming environment Simulink that suppo...

This paper presents an approach to software assessment using a new software tool that integrates most of the known static metrics. A six-step method shows how to use metrics to obtain a picture of the software project. The method is visual and each step provides graphical representations of the data. Successive integration of data results in normality profiles. Examples illustrate each step. Th...

A galaxy model is a multidimensional model dedicated for XML document warehouses. It can be seen as a network of entities (i.e., dimensions) connected via nodes. After giving an overview of our four-steps semiautomated method for the generation of galaxy models which aims to build data marts from XML documents. This paper focuses on the software tool, called Galaxy-Gen that implements the propo...

There are two main issues to be resolved in order that design tools can be used in cooperative mode, each communicating with the other. Firstly, there is a need to put in place a consistent product model of a building and its systems from which disparate design tools can obtain their inputs and return their outputs. Secondly, there is the requirement to manage the transactions between users and...

Computer forensic techniques may be unfairly applied in order to tip the scales of justice in the direction of prosecution. Particular areas that are known to be problematic for defense experts include: erroneous allegations of knowledgeable possession; misuse of time stamps and metadata; control and observation of the discovery process; authentication issues; deficiencies and the lack of verif...

Schedule pressures often force development managers to seek strategies to compress project time scales. Typical strategies might include adding more people, investing in development tools, improving hardware, and improving development methods. Is it possible to see which of these strategies is most effective? In this research we concentrate on the application of people to achieve time compression.

Osteotomies around the knee address lower limb deformities that affect the leg posture and especially the knee joint. Knee arthritis is a very common age-related joint disease that can be treated with osteotomy, as an alternative to knee replacement by implants. The preoperative planning process is demanding and significantly determines the surgical out-come. The choice of the osteotomy type an...
