A Study on the Tone-Reservation Technique for Peak-to-Average Power ...

by Umer Ijaz Butt

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, ...

Performance Optimization of IP Multimedia Subsystem (IMS)

by Mlindi Mashologu

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 ...

Computational Model of Listener Behavior for Embodied Conversational ...

by Elisabetta Bevacqua

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, ...

A Pattern-oriented Approach to Stakeholder Communications

by Cornelis Pieter Pieters

The NWO-programme "the societal aspects of genomics", has called for stronger means of collaboration and deliberative involvement between the various stakeholders of genomics research. Within the project group assembled at the UH, this call was translated to the 'lingua democratica', in which the prerequisites of such ...

A Security Framework for Mobile Agent Systems

by Omer Mansoor Paracha

Agent technology is a novel approach for the development of distributed systems. In particular, mobile agents can provide much greater flexibility and robustness than the traditional distributed system methodologies since they provide mobility from platform to platform. Thus, they form a vast area of research. One key ...

Multimodal Distinctive Behavior for Expressive Embodied ...

by Maurizio Mancini

Embodied Conversational Agents (ECAs) are a new type of computer interface which have human-like bodies and conversational skills. Users interacting with agents will be more engaged and participative if the agents exhibit behaviors which look coherent across different situations and emotional states. In the present ...

Toponym Resolution in Text

Annotation, Evaluation and Applications of Spatial Grounding of Place Names

by Jochen L. Leidner

The problem of automatic toponym resolution, or computing the mapping from occurrences of names for places as found in a text to an unambiguous spatial footprint of the location referred to, such as a geographic latitude/longitude centroid is difficult to automate due to insufficient and error-prone geographic ...

Computer Simulation Using Excel without Programming

by Evon M. O. Abu-Taieh

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 ...
