Online adaptative zero-shot learning spoken language understanding using word-embedding

Many recent competitive state-of-the-art solutions for understanding of speech data have in common to be probabilistic and to rely on machine learning algorithms to train their models from large amount of data. The difficulty remains in the cost and time of collecting and annotating such data, but also to update the existing models to new […]

Proposition and demonstration of 3tr. type ion image sensor pixel structure for highly resolution bio-imaging

We propose a pixel construction for a pH image sensor with a new measurement method that spills charge to a potential wall under sensing area. The sensor pixel with 3 transistors has advantages for fabricating the sensor array with high spatial resolution compared with a conventional ISFET type sensor array using 4 transistors. The pixel […]

Design and optimization of a shaped-beam ka-band substrate integrated waveguide antenna array

Millimeter-wave antenna array Beam Forming Networks in Substrate Integrated Waveguide (SIW) technology are an attractive alternative to the use of TEM transmission lines, such as microstrip or stripline. SIW allows reducing the transmission losses while maintaining low price and simple, yet accurate, fabrication of the Printed Circuit Board technology. However, SIW design has additional restrictions and limitations […]

Low-Cost Compact Circularly Polarized Directional Antenna for Universal UHF RFID Handheld Reader Applications

A low-cost compact circularly polarized (CP) directional antenna is proposed for universal ultra-high frequency (UHF) RF identification (RFID) handheld reader applications. The antenna consists of four sequentially rotated inverted-F antennas (IFAs) fed by a compact four-feed network with closed-form design formulas. A prototype is implemented by FR-4 substrates and a thick air layer for the reduction of […]

Covariance Shapes as a Cognitive Radio Concept for Receivers with Multiple Antennas

Non-orthogonal access in cognitive radio is typically controlled by limiting the interference power caused to the primary network by so-called interference temperatures. For receivers with multiple antennas the definition of a scalar measure for the impact of interference is ambiguous and the generalization of interference temperatures is non-trivial. We propose a cognitive radio concept by imposing constraints, […]

A Performance-Guided Graph Sparsification Approach to Scalable and Robust SPICE-Accurate Integrated Circuit Simulations

To improve the efficiency of direct solution methods in SPICE-accurate integrated circuit simulations, preconditioned iterative solution techniques have been widely studied in the past decades. However, it is still an extremely challenging task to develop robust yet efficient general-purpose preconditioning methods that can deal with various types of large-scale integrated circuit problems. In this work, […]

Finite-time consensus for second-order multi-agent systems with saturated control protocols

This study investigates the distributed finite-time consensus problem of networked agents with second-order integrators. First of all, to achieve finite-time consensus, a saturated protocol is proposed based on both relative position and relative velocity measurements. In light of the tools from homogeneous theory, it is theoretically shown that the proposed protocol will guarantee finite-time consensus under bounded […]

A Single-phase PV Quasi-Z-source Inverter with Reduced Capacitance using Modified Modulation and Double-Frequency Ripple Suppression Control

In single-phase photovoltaic (PV) system, there is double-frequency power mismatch existed between the dc input and ac output. The double-frequency ripple (DFR) energy needs to be buffered by passivenetwork. Otherwise, the ripple energy will flow into the input side and adversely affect the PV energy harvest. In a conventional PV system, electrolytic capacitors are usually […]
