International practice, including international instruments and case law, confirms that states generally accept they have a duty to provide prior notification of planned measures may significant adverse effect upon co-riparians. The principle “prior notification” is framed differently in various instruments, it can broadly include the “notify” “consult” on measures. Prior helps prevent mitigate...

Zephyr is a notice transport and delivery system under development at Project Athena.1 Zephyr is for use by network-based services and applications with a need for immediate, reliable and rapid communication with their clients. Zephyr meets the highthroughput, high fan-out communications requirements of large-scale workstation environments. It is designed as a suite of ‘‘layered services’’ base...

CORBA is a promising software platform for CSCW applications. However, the current CORBA ORBs only provide low-level services. Building CSCW applications is still a complex task. In this paper, we discuss how a common notification service can be added to the CORBA architecture to deal with common user interface events in a distributed environment. This notification service is based on the alrea...

Groupware applications used in distributed office environments are characterized by several users accessing and manipulating a shared document pool in a collaborative context. Supporting such application with relational database persistence and object technology requires two main features: (1) a sound and generic mapping from the object-oriented application schema to the relational data model, ...

IEEE 802.11 technology becomes attractive with the implementation of various broadcast applications. For these applications, one of the main performance indices is the mean notification time namely the interval between consecutive successful receipts of the same source’s packets. In this paper, we develop an analytical method to study the ad hoc 802.11 network performance with broadcasting stat...

Informing of a patient's death is difficult for physicians as well as patient's families. Breaking bad news is part of clinical experience of physicians and existential experience of patient's close relatives. The professional manner of death notification may effectively reduce the level of stress and other negative emotions in both parties involved. Special information procedures defining card...

Event notification services, or alerting services, are used in various applications such as digital libraries, stock tickers, traffic control, or facility management. However, to our knowledge, a common semantics of events in event notification services has not been defined so far. In this paper, we propose a parameterized event algebra which describes the semantics of composite events for even...

Kqueue event notification API is implemented for Linux in the form of a loadable kernel module. Existing BSD applications that use kqueue API were ported to Linux and approved the correct implementation functionality. Event requests are preserved in the kernel and thus improvement for long-living connections over standard poll mechanism was achieved. Detailed survey of existing event notificati...
