Complex overlapping concepts: An effective auditing methodology for families of similarly structured BioPortal ontologies

  • Chen Y.
  • Elhanan G.
  • Geller J.
  • Ochs C.
  • Perl Y.
  • Zheng L.

In previous research, we have demonstrated for a number of ontologies that structurally complex concepts (for different definitions of ?complex?) in an ontology are more likely to exhibit errors than other concepts. Thus, such complex concepts often become fertile ground for quality assurance (QA) in ontologies. They should be audited ...

Opportunistic Spatial Preemptive Scheduling For URLLC and eMBB Coexistence in Multi-User 5G Networks

  • Esswie A.
  • Pedersen K.

The fifth generation (5G) of the mobile networks is envisioned to feature two major service classes: ultra-reliable low-latency communications (URLLC) and enhanced mobile broadband (eMBB). URLLC applications require a stringent one-way radio latency of 1 ms with 99.999% success probability while eMBB services demand extreme data rates. The coexistence of ...

© 2018 Informa UK Limited, trading as Taylor & Francis Group We investigate the dynamic relationship between coffee exports and machinery imports in Brazil from 1869 to 1939. Our tests reveal cointegration and bidirectional causality in the temporal sense. This evidence suggests that foreign exchange real revenues from coffee exports ...

Performance of Balanced Fairness in Computer Clusters: A Recursive Approach

  • Bonald T.
  • Comte C.
  • Mathieu F.

Understanding the performance of computer clusters is crucial for proper dimensioning. One of the main challenge is to take into account the complex interactions between computers that process jobs in parallel. In particular, a job can generally not be processed by any computer of the cluster due to various constraints ...

We are evolving to a world where multi-sensory experiences and new interaction modalities become increasingly important. A world where human augmented intelligence - based on massive amounts of available data - is expected to change our lives in drastic ways. We are moving to an IoT world where information sources ...

On Coding for Cache-Aided Delivery of Dynamic Correlated Content

  • Erkip E.
  • Hassanzadeh P.
  • Llorca J.
  • Tulino A.

IEEE Cache-aided coded multicast leverages side information at wireless edge caches to efficiently serve multiple unicast demands via common multicast transmissions, leading to load reductions that are proportional to the aggregate cache size. However, the increasingly dynamic, unpredictable, and personalized nature of the content that users consume challenges the efficiency ...

DARN: Dynamic Baselines for Real-time Network Monitoring

  • Mijumbi R.

Network monitoring is necessary so as to ensure high reliability and availability in telecom networks. One of the main challenges posed by state-of-the-art monitoring tools is the creation of network baselines. Such baselines include thresholds that can be used to determine whether monitored values (with a given context, e.g. time) ...

FPGA-Centric Design Process for Avionic Simulation and Test

Real-time computing systems are increasingly used in aerospace and avionic industries. In the face of power challenge, performance requirements and demands for higher flexibility, hardware designers are directed toward reconfigurable computing using field programmable gate arrays (FPGAs) that offer high computation rates per watt and adaptability to the application constraints. ...

Massive MIMO Unlicensed: A New Approach to Dynamic Spectrum Access

Nowadays, the demand for wireless mobile services is copious and will continue increasing in the near future. Mobile cellular operators are therefore looking at the unlicensed spectrum as an economical supplement to augment the capacity of their soon-to-be overloaded networks. The same unlicensed bands are luring Internet service providers, venue ...

Scaling factor optimization of turbo-polar iterative decoding

In this paper, we investigate the weighted iterative decoding to improve the performance of turbo-polar code. First of all, a minimum weighted mean square error criterion is proposed to optimize the scaling factors (SFs).
