In the product-centered marketing times of telecom industry, BOSS (Business Operations Supporting System) was established step by step, which resulted in the two critical difficulties in customer profile integration: semantic inconsistency and semantic conflict. In this article, ontology theory is introduced to solve these problems. Firstly, the skeleton method is adopted to build telecom custo...

Nonclassical correlations between a C-band telecom photon and a stored spin-wave Farrera, Pau; Maring, Nicolas; Albrecht, Boris; Heinze, Georg; de Riedmatten, Hugues Published in: Optica DOI: 10.1364/OPTICA.3.001019 Publication date: 2016 Document Version Publisher's PDF, also known as Version of record Citation for published version (APA): Farrera, P., Maring, N., Albrecht, B., Heinze, G., & d...

We present a spectrally decorrelated photon pair source bridging the visible and telecom wavelength regions. Tailored design and fabrication of a solid-core photonic crystal fiber (PCF) lead to the emission of signal and idler photons into only a single spectral and spatial mode. Thus no narrowband filtering is necessary and the heralded generation of pure photon number states in ultrafast wave...

The Spoken Web project is building a telecom Web that provides a platform for information access and collaborative problem-solving for the developing world. Phone-based audio navigation to relevant content in this new kind of Web has become a major challenge. In this paper we delineate the opportunities for applying collaborative filtering to improve audio navigation on the telecom Web and desc...

The IP Multimedia Subsystem (IMS) defined by the 3GPP has been mainly developed and deployed by telephony vendors on vendor-specific hardware. Recent advances in Network Function Virtualisation (NFV) technology paved the way to virtualized hardware and telephony function elasticity. As such Telecom vendors start to embrace the cloud as a deployment platform usually selecting a privileged virtua...

The Canadian Information and Communication Technology (ICT) accounted for $60.6 billion to Canadian Gross Domestic Product (GDP) by 2006. In this paper, we analyze the dynamics and the key factors involved in the downfall of the ICT sector during the period of 2000-2003. In particular, we discuss factors including low-cost capital, irrational forecasts, excessive investment in innovative soluti...

Carrier-grade systems in today’s telecom market have high availability needs; however, current market conditions are forcing telecom equipment providers to look for lower-cost alternatives. In this paper, we discuss Advanced Telecom Computing Architecture (AdvancedTCA), Carrier-Grade Linux (CGL), and how these standards meet the requirements of carrier-grade equipment. We also describe how both...

The size and number of telecom databases are growing quickly but most of the data has not been analyzed for revealing the hidden and valuable intellectual. Models developed from data mining techniques are useful for telecom to make right prediction. The dataset contains one million customers from a telecom company. We implement data mining techniques, i.e., AdaboostM1 (ABM) algorithm, Naïve Bay...

Practical quantum communication between remote quantum memories rely on single photons at telecom wavelengths. Although spin-photon entanglement has been demonstrated in atomic and solid-state qubit systems, the produced single photons at short wavelengths and with polarization encoding are not suitable for long-distance communication, because they suffer from high propagation loss and depolari...

Indoor environment can be characterized as sever attenuating and depolarizing medium for electromagnetic (radio) waves propagation. These signals are radiated from transmitters to space (free-space propagation channel) and received from space to receivers through antennas. These signals are commonly radiated or received with pre-defined signal’s polarization schemes and these schemes are always...
