Managing inter-cell interference with advanced receivers and rank adaptation in 5G small cells

The use of receivers with interference suppression capabilities is expected to be a significant performance booster in 5th Generation (5G) ultra-dense small cell networks. In this respect, they could represent an alternative to traditional frequency reuse techniques, facilitating the inter-cell interference management. In this paper, we evaluate whether it is possible to rely on such advanced […]

Thwarting Intelligent Malicious Behaviors in Cooperative Spectrum Sensing

Sensing falsification is a key security threat in cooperative spectrum sensing in cognitive radionetworks. Intelligent malicious users (IMUs) adjust their malicious behaviors according to their objectives and the network’s defense schemes. Without long-term collection of information on users’ reputation, the existing schemes fail to thwart such malicious behaviors. In this paper, we construct a joint […]

A Generalized Approach for Computing Most Sensitive Eigenvalues With Respect to System Parameter Changes in Large-Scale Power Systems

The recently-developed Two-sided Arnoldi and Sensitive Pole Algorithm (TSA-SPA) is effective and robust in computing the most sensitive eigenvalues with respect to control parameter changes in large-scale power systems. This paper extends the TSA-SPA to handle different system parameters, including control, system operating and network parameters. The proposed algorithm makes use of perturbation in reduced matrix obtained […]

Influence of shunt compensation with SVC devices on resonance risk in power systems

Many analyses are required to locate a new reactive power source in a power system. The choice of a location is a very complex matter which requires various aspects to be considered. Selecting a location also entails the necessity to assess it from the point of view of the selected compensator’s structure as well as […]

A Dissipativity Approach to Safety Verification for Interconnected Systems

We propose a computational method for verifying a state-space safety constraint of a network of interconnected dynamical systems satisfying a dissipativity property. We construct an invariant set as the sublevel set of a Lyapunov function comprised of local storage functions for each subsystem. This approach requires only knowledge of a local dissipativity property for each subsystem and […]

Photonic integrated transceiver for data readout systems

This study presents a photonic integrated transceiver for application in a data readout unit of a sensornetwork. The device was realized in a generic InP-based technology. The circuit uses an asymmetric coupler and a PIN photodiode for input signal detection and a Mach-Zehnder amplitude modulator for encoding of output sensor data. Small-signal modulation bandwidth of […]

RAISE: A Whole Process Modeling Method for Unstructured Data Management

Nowadays, unstructured data, e.g., texts, images, and videos, is growing in an explosive speed with the development of Internet and social network. Due to the variety of unstructured data, it is strongly desirable to design a generalized model to represent all kinds of unstructured data and build a system to organize them effectively. In this paper, […]

Coding Local and Global Binary Visual Features Extracted From Video Sequences

Binary local features represent an effective alternative to real-valued descriptors, leading to comparable results for many visual analysis tasks while being characterized by significantly lower computational complexity and memory requirements. When dealing with large collections, a more compact representation based on global features is often preferred, which can be obtained from local features by means […]

Mobile Ticket Dispenser System With Waiting Time Prediction

A ticket dispenser (TD) is used to assist customers with the waiting process in, e.g., a restaurant. This paper deploys a mobile TD system (MTDS) with waiting time prediction to enhance the user experience while waiting. For example, the MTDS for a restaurant allows a customer to remotely draw a ticket for a meal order […]
