Interconnection across administrative boundaries prompts the need for comprehensive policy enforcement (i.e., access control) with respect to inter-domain packet traac. Due to the nature of the communication services they provide, stub and transit domains require diierent mechanisms for policing inter-domain traac. This paper addresses the design of a policy enforcement mechanism geared speciic...

The InfiniBand(tm) Architecture is a new industry-standard architecture for server I/O and inter-server communication. It was developed by the InfiniBand(sm) Trade Association, a collaboration of over 200 companies including all the major server vendors, to provide the reliability, availability, performance, and scalability needed in server systems. This talk will provide an overview of InfiniB...

Software architecture decisions pay primary attention to nonfunctional requirements (NFRs), yet use cases normally describe functional requirements. This article presents scenario-based descriptions of Architectural Concerns to satisfy NFRs and of Architectural Policies that represent architectural choices to address such concerns. The Azimut framework combines these modeling abstractions with ...

Actually, multiprocessor architecture is one of the solutions to fulfill the heavy computational requirements of the new applications running on embedded systems such multimedia and 3D games. The design of such systems pose various problems located at different level: architecture topology, lack of multiprocessor RTOS. Hence, we suggest in this paper a new topology of multiprocessor architectur...

The aim of this research was to validate a new procedure (SkanLab) for the three-dimensional estimation of total arm volume. SkanLab is based on a single structured-light Kinect sensor (Microsoft, Redmond, WA, USA) and on Skanect (Occipital, San Francisco, CA, USA) and MeshLab (Visual Computing Lab, Pisa, Italy) software. The volume of twelve plastic cylinders was measured using geometry, as th...

Multi-agent systems benefit greatly from an organization design that guides agents in determining when to communicate, how often, with whom, with what priority, and so on. However, this same organization knowledge is not utilized by general-purpose wireless network routing algorithms normally used to support agent communication. We show that incorporating organization knowledge (otherwise avail...

This paper presents a novel robotic architecture that is suitable for modular distributed multi-robot systems. The architecture is based on an interface supporting real-time inter-process communication, which allows simple and highly efficient data exchange between the modules. It allows monitoring of the internal system state and easy logging, thus facilitating the module development. The exte...

Background/objectives: The key to HIV/STI control is community-wide intervention (CWI) which depends heavily on continuous monitoring and evaluation. Unfortunately, comprehensive CWI assessment methodology and reports are generally lacking. This study developed, applied, and evaluated a rapid tool for assessing CWI in China. Methods: A total of 120 county level respondents in charge of county-w...

The paper describes a corpus of texts produced by non-native speakers of Czech. We discuss its annotation scheme, consisting of three interlinked tiers, designed to handle a wide range of error types present in the input. Each tier corrects different types of errors; links between the tiers allow capturing errors in word order and complex discontinuous expressions. Errors are not only corrected...
