In this paper, we present our behavioral SDL model for the IEEE 802.15.3 MAC protocol. The model was derived using an object-oriented approach based on the client/server paradigm and is divided into data path and control path subsystems. Within the model, there are different abstraction layers, each layer providing a welldefined set of services to the higher layers. This modular design approach...

The overall behavior and nature of complex natural systems is in large part determined by the number and variety of the mechanisms involved – and the complexity of their interactions. Embodied natural communication belongs to this class of systems, encompassing many cognitive mechanisms that interact in highly complex ways, both within and between communicating individuals, constituting a heter...

The Mainz Rolling Brains 2001 team is based on our last year’s team. Our modular design as described in [1] has proved to be efficient and flexible. Thus the team could easily be adopted to the soccerserver’s new features and some of the weak spots of our team could be eliminated. We use a three-layers concept for our agents: a technical layer (purely technical matters like server communication...

This paper presents a study of bimanual control applied to sound synthesis. This study deals with coordination, cooperation, and abilities of our hands in musical context. We describe examples of instruments made using subtractive synthesis, scanned synthesis in Max/MSP and commercial stand-alone software synthesizers via MIDI communication protocol. These instruments have been designed accordi...

We present a new scalable fault-tolerant algorithm which ensures total order delivery of messages sent to multiple groups of processes. The algorithm is scalable in the sense that: (1) any process can multicast a message to one or more groups of processes without being forced to join those groups; (2) inter-group total order is ensured system-wide but, for each individual multicast, the number ...

In this paper, related product functions are determined for a group of approximately 70 consumer products. Using customer need data, a new matrix approach is introduced to identify these relationships. Techniques are then created for determining product similarity. These techniques are clarified and validated through three case studies, including beverage brewers and material-removal products. ...

Over the last decade there has been an increasing interest on power drive train topologies for hybrid electric fuel cell vehicles. A review of previous publications revealed that little work provided direct comparisons between the topologies. This paper details the development of a simulation model that has formed the basis of an assessment of all the topologies, addressing the advantages and d...

The Click modular router was designed to forward packets, but some of its strengths—modular design, speed, and scalability—are well suited for measurement tasks as well. We present simple and efficient Click elements that process traces and live packet data, and configurations and tools that combine those elements in useful ways.

The Digital Assets Repository (DAR) is a system developed at the Bibliotheca Alexandrina to manage the full lifecycle of a digital asset: its creation and ingestion, its metadata management, storage and archival in addition to the necessary mechanisms for publishing and dissemination. In its third release, the system architecture has been revamped into a modular design including components that...

Machine virtualization is undoubtedly useful, but does not come cheap. The performance cost of virtualization, for I/O intensive workloads in particular, can be heavy. Common approaches to solving the I/O virtualization overhead focus on the I/O stack, thereby missing optimization opportunities in the overall stack. We propose VAMOS, a novel software architecture for middleware, which runs midd...
