This paper describes a telerobotic system operated through a virtual reality (VR) interface. A least squares method is used to find the transformation mapping, from the virtual to real environments. Results revealed an average transformation error of 3mm. The system was tested for the task of planning minimum time shaking trajectories to discharge the contents of a suspicious package onto a wor...

This paper presents an initial implementation of a Virtual Ultrasound Imaging System as an interactive educational tool for students and researchers in the medical ultrasound imaging field. The system uses a cause and effect approach for understanding the results of changing transducer attributes and pulse parameters on the quality of the ultrasound image. The elements of the system include Fie...

1 Motivation In recent years, many researchers have explored mechanisms that allow systems to span large networks. Few, however, have looked at the problems that will confront the users of these highly distributed systems. There will be a huge amount of information available within such a system, and that information will be scattered about. Even if users can access it all, there will be so muc...

Annotation is a key operation for developing understanding of complex data or extended spaces. We have developed a flexible set of annotation tools that can be placed in a variety of applications. These tools offer a full set of capabilities for inserting, iconizing, playing back, and organizing annotations in a virtual space. They also have an intuitive and easy-to-use interface for employing ...

Electronic Health Records are key components to an efficient exploitation of information technologies in health care institutions. Nevertheless, several barriers that hinder its wide adoption subsists. The co-existence of dissimilar and incompatible health information systems and the absence of a unique central repository for personal medical data are some examples. This paper, we propose a web...

The main problem is less efficiency and blocking during sugarcane harvesting in hilly areas. This paper researched the cutting and transporting system of a small sugarcane harvester using virtual prototype technology. The dynamics simulation analyses were carried out to study the transporting status with different friction coefficients between the sugarcane and the spiral and different numbers ...

The objective of the VES project is the research and development of innovative techniques and solutions for the achievement of a virtual examination environment in echocardiography. One crucial point is the development of realistic geometric models representing the diseased human heart. For this purpose we decided to use real echocardiography findings as a starting position. The modelling and v...

Companies conduct world-wide collaborations which often involve asynchronous work with group members in di erent time-zones. In asynchronous work, the participants can easily waste days just clarifying questions because feedback is slow. For e cient collaborations, accurate \handing-o " of work between participants is crucial. Therefore, messages exchanged between collaborators should not conta...

In this study, a Virtual Learning System that integrates Virtual Classroom and Virtual Laboratory services is presented. The Virtual Classroom represents an interface between the students and a virtual professor and provides personalized learning materials to the users. The Virtual Laboratory offers a possibility to the attendees to share different resources at once and work with them as if the...

Implementing and maintaining file systems is painful. OS functionality is notoriously difficult to develop and debug, and file systems are more so than most because of their size and interactions with other OS components. In-kernel file systems must adhere to a large number of internal OS interfaces. Though difficult during initial file system development, these dependencies particularly compli...
