This memo specifies the Common Presence and Instant Messaging (CPIM) Presence Information Data Format (PIDF) as a common presence data format for CPIM-compliant Instant Messaging and Presence protocols, and also defines a new media type "application/cpim-pidf+xml" to represent the XML MIME entity for PIDF.

Anti-slug control of multiphase risers involves stabilizing an open-loop unstable operating point. PID control is the preferred choice in the industry, but appropriate tuning is required for robustness. In this paper, we define PIDF as a PID with a low-pass filter on its derivative action where the low-pass filter is crucial for the dynamics. We compared a new PIDF tuning based on Internal Mode...

This work aims to develop a controller based on auto tuning 0f PIDF to simulate an automatic voltage regulator (AVR) in transient stability power system analysis. AVR is an essential part of the synchronous generator and it is responsible for regulating the reactive power and voltage level under normal operating terms at various load levels. The modeled system consisted of theamplifier, exciter...

The Presence Information Document Format (PIDF) specifies the baseline XML-based format for describing presence information. One of the characteristics of the PIDF is that the document always needs to carry all presence information available for the presentity. In some environments where low bandwidth and high latency links can exist, it is often beneficial to limit the amount of transported in...

We report here a polarization-independent drop filter (PIDF) based on a photonic crystal self-collimation ring resonator (SCRR). Despite of the large birefringence associated with the polarization-dependent dispersion properties, we demonstrate a PIDF based on multiple-beam interference theory and polarization peak matching (PPM) technique. The PIDF performance was also investigated based on fi...

Presence Information Data Format (PIDF) defines a common presence data format for Common Profile for Presence (CPP) compliant presence protocols. This memo defines a PIDF extension to represent SIP User Agent capabilities. Lonnfors & Kiss Standards Track [Page 1] RFC 5196 User Agent Capability Presence Status September 2008 Table of

The Presence Information Data Format Location Object (PIDF-LO) specification provides a flexible and versatile means to represent location information. There are, however, circumstances that arise when information needs to be constrained in how it is represented. In these circumstances, the range of options that need to be implemented are reduced. There is growing interest in being able to use ...
