This document explores an ambiguity in the interpretation of the element of the Presence Information Data Format for Location Objects (PIDF-LO) in cases where PIDF-LO is conveyed by the Session Initiation Protocol (SIP). It provides recommendations for how the SIP location conveyance mechanism should adapt to this ambiguity. Documents standardizing the SIP location conv...

In this paper we present a distributed and modular system to convey small and fragile objects. This is done by attaching similar modular blocks together to form a larger conveyance surface. Similar to other networked control systems, each block is composed of several sensors, actuators and communication infrastructure. Control of a levitating object should be done distributed and real-time. We ...

An Anglo-Indian, asked to mention the principal annoyances attending every-day life in this country, would probably catalogue heat, musquitoes, sparrows, and various kinds of winged insects, not forgetting the irrepressible house fly?a dipteron which, whether acting under dense ignorance of danger, or whether influenced by pure impudence, does not hesitate to explore, even at the risk of destru...

Abstract This research is based on a new drilling fluids circulation treatment device, which belongs to solid control system, namely pulsating negative pressure shale shaker. The purpose of this article better understand the operating principle and provide basis for setting working parameters optimizing design. above content depends dynamic analysis throwing motion particles. To be specific, eq...
