Investigating the Feasibility of Open Development of Operations Support Solutions

The telecommunications Operations Support Systems supply chain must address many stakeholders: R&D, Product and Requirements Management, Purchasing, Systems Integration, Systems Administration and Users. While the management of next generation networks and services poses significant technical challenges, the present supply chain, market configuration, and business practices of the OSS community are an obstacle to rapid innovation. Forums for open development could potentially provide a medium to shorten this supply chain for the deployment of workable systems. This paper discusses the potential benefits and barriers to the open development of OSS for the telecommunications industry. It proposes the use of action research to execute a feasibility study into the open development of OSS software solutions within an industry wide Open OSS project

Lithologic Controls on Focused Erosion and Intraplate Earthquakes in the Eastern Tennessee Seismic Zone

We present a new geomorphic model for the intraplate eastern Tennessee seismic zone (ETSZ). Previous studies document that the Upper Tennessee drainage basin is in a transient state of adjustment to ~150 m of base level fall that occurred in the Late Miocene. Using quantitative geomorphology, we demonstrate that base level fall resulted in the erosion of ~3,500 km3 of highly erodibility rock in an ~70 km wide by ~350‐km‐long corridor in the Paleozoic fold‐thrust belt above the ETSZ. Models of modern incision rates show a NE‐SW trending swath of elevated erosion ~30 km southeast of the center of the ETSZ. Stress modeling shows that lithologically focused erosion has affected fault clamping stress on preexisting, favorably oriented faults. We argue that the lithologically controlled transient erosional response to base level fall in the Upper Tennessee basin has given rise to and is sustaining earthquake activity in the ETSZ

Improving the practice of Operations Support Systems in the Telecommunications Industry using Open Source

This document fulfils the requirements for the final Thesis in completion of an Engineering Doctorate program at the University of Southampton. This Thesis presents the findings of a three and a half year Engineering Doctorate study (2003-2007) which investigated the options for open source in delivering Operational Support Systems (OSS) to the global telecommunications industry. The principal mode of investigation has been Action Research in collaboration with a number of industry players and in support of the New Generation Operations Support Systems (NGOSS) standardisation activities conducted under the auspices of the Telemanagement Forum (www.tmforum.org). The thesis considers the use of open source to expedite the creation and dissemination of emerging ass standards through a number of collaborative industrial projects including a Next Generation Network proof .' ofconcept and a novel application ofNGOSS to the problem ofmanaging a digital TV network. Conclusions are drawn as to the benefits which service providers could derive from using open source as a key factor in managing the strategic risks and costs associated with the new product introduction process. The principal contribution has been to develop within the telecommunications industry a greater understanding and acceptance ofthe role which open source can have in the delivery ofOSS solutions.

The OpenOSS Project - An open Source operations Support Lab for the Telecommunications Industry.

This paper discusses the aims, objectives and early deliverables from the OpenOSS project which has been set up with the sponsorship of a number of Telecommunications Service Providers to investigate thepotential value of open source as an enabler for rapid innovation within the telecommunications industry. This paper also reports on the success of an initial proof of concept of OpenOSS which was pubically demonstrated t the telecommunications industry in Nice at the 2005 Telemanagement World Conference. We consider the practical business and technical benefits and challenges of using open source development in this way and report on our plans to take the project to the next stage of development

Experimental determination of the gas phase proton affinities of the conjugate base anions of 2-iodoxybenzoic acid (IBX) and 2-iodosobenzoic acid (IBA)

The gas phase anion proton affinities of the periodinane anions IBX and IBA were examined using mass spectrometry-based experiments, and estimated as 1300 ± 25 and 1390 ± 10 kJ mol , respectively. The experimental results were supported by theoretical calculations, which yielded proton affinities of 1336 and 1392 kJ mol for IBX and IBA respectively, at the B3LYP/aug-cc-PVDZ level of theory
