An Investigation into the Surface Skidding Response of PBX 9501 and PBX 9502

Propellants, Explosives, Pyrotechnics, 2022
AbstractWhile polymer‐bonded explosives, PBX, have reduced sensitivity to ignition from mechanical shock or heating compared to conventional explosives, the investigation of the mechanical ignition mechanisms for PBX remains vital to assessing the safety during machining and general handling.

Preparation and thermal properties study of HNIW/FOX-7 based high energy polymer bonded explosive (PBX) with low vulnerability to thermal stimulations

Journal of Energetic Materials, 2019
For modern munitions, high energy explosives are expected to reduce vulnerability and improve safety. In this study, based on the formulation of PAX-11 (94 wt% HNIW, 2.4 wt% CAB, 3.6 wt% BDNPA/F), FOX-7 is used as a portion replacement for HNIW to ...

Asterisk PBX Capacity Evaluation

2015 IEEE International Parallel and Distributed Processing Symposium Workshop, 2015
A VoIP communication infrastructure may need to serve a substantial number of users with an acceptable voice quality. This paper investigates the suitability of the Asterisk PBX server to provide VoIP communication capabilities with an acceptable Mean Opinion Score (MOS) quality to a large number of users.

Office communications and the digital PBX

Computer Networks (1976), 1981
Abstract As part of a study on office automation, we have investigated two related topics: voice and data communications on local office networks, and the use of a computerized PBX as a switch in an office network. Since a computerized PBX might be an effective method for implementing a voice/data office network, we have addressed the important ...

The Evolution of Data Switching for PBX's

IEEE Journal on Selected Areas in Communications, 1985
This paper compares and contrasts the different traffic requirements of both voice and data communications. The role of evolving PBX technology in solving data communication needs is outlined, beginning with the analog PBX's of the 1970's and the digital-switching technology of the 1980's.

Towards junking the PBX

Proceedings of the 11th international workshop on Network and operating systems support for digital audio and video, 2001
We describe the architecture and implementation of our Internet teleph ony test-bed intended to replace the departmental PBX (telephone switch). It interworks with the traditional telephone networks via a PSTN/IP gateway. It also serves as a corporate or campus infrastructure for existing and future services like web, email, video and streaming media.

Survey of Digital PBX Design

IEEE Transactions on Communications, 1979
It is the purpose of this paper to discuss the capabilities and organization of all digital PBX's currently being manufactured in the United States. A digital PBX is one which encodes incoming signals into representations where the presence, or absense, of pulses, or levels, defines the signal; such a system switches signals by routing, multiplexing ...
