The main problem addressed by this work is how to model and combine bodies of knowledge (or evidence) while maintaining the representation of the unkowledge and of the conflict among the bodies. This is a problem with far-reaching applications in many knowledge segments, in particular for the fields of artificial ...

During a conversation, listeners do not assimilate passively all of the speaker's words; they actively participate in the interaction providing information about how they feel and what they think of the speaker's speech. The speaker relies on signals emitted by the listener to know if he is listening or not, ...

The IP Multimedia Subsystem (IMS) is the basic network architecture for Next Generation Networks (NGN) which is intended to bridge the divide between the traditional circuit switched and packet switched networks, thereby providing a single network capable of providing all service offerings. IMS is based on the IP ...

Emergency and disaster response teams utilize information technology (IT) systems heavily to get up-to-the-minute information that will help them do their jobs effectively and safely. The use of new communication and information technologies not only allows for better exchange of information among organizations, but ...

"Liberal order and software-agents" - long-established ideas and modern technology are bridged. The impulse for undertaking this effort comes from the observation that it becomes difficult for computer science alone to create order for and within machines. The growing complexity of computer systems, open networks like ...

Multicarrier Modulation (MCM) has significant features over Single Carrier Modulation (SCM). Orthogonal Frequency Division Multiplexing (OFDM) is a special form of Multicarrier Modulation with its key feature of Orthogonality. Along with the several advantages of MCM or specifically OFDM, it has some drawbacks, too, ...

Gamma ray detection techniques for radioisotope imaging purposes are quickly evolving. Monte Carlo simulations show the possibility of achieving an outstanding image spatial resolution in the images obtained with techniques using electronic collimation. The great advantage of using electronic collimation is the ...

This dissertation introduces new hardware architectures for more realistic surface rendering of three dimensional objects and the rendering of volumetric datasets. Surface rendering is dealt with in the first part of the dissertation where the architectures for displacement map rendering in hardware are proposed. This ...

Defining Simulation in its broadest aspect as embodying a certain model to represent the behavior of a system, whether that may be an economic or an engineering one, with which conducting experiments is attainable. Such a technique enables the management, when studying models currently used, to take appropriate ...

Researchers and data analysts are increasingly relying on graphical tools to assist them in modeling their data, generating their hypotheses, and gaining deeper insights on their experimentally acquired data. Recent advances in technology have made available more improved and novel modeling and analysis media that ...
