Low Cost Disaggregation of Smart Meter Sensor Data
(2016)This paper proposes a novel load disaggregation algorithm, based on non-intrusive appliance monitoring that provides accurate results without the need of the reactive power component. The proposed technique requires the ... -
A low-power CMOS VLSI circuit for signal conditioning in integrated capacitive sensors
(2004)Capacitive sensor manufacturing processes are rarely compatible with CMOS technologies and, thus, monolithic integration of sensing device and signal-conditioning IC is often not possible. Multi-chip packaging and wire ... -
Multi-channel non-negative matrix factorization for overlapped acoustic event detection
(2018)In this paper, we propose two multi-channel extensions of non-negative matrix factorization (NMF) for acoustic event detection. The first method performs decision fusion on the activation matrices produced from independent ... -
Multi-microphone fusion for detection of speech and acoustic events in smart spaces
(2014)In this paper, we examine the challenging problem of detecting acoustic events and voice activity in smart indoors environments, equipped with multiple microphones. In particular, we focus on channel combination strategies, ... -
Multi-room speech activity detection using a distributed microphone network in domestic environments
(2015)Domestic environments are particularly challenging for distant speech recognition: reverberation, background noise and interfering sources, as well as the propagation of acoustic events across adjacent rooms, critically ... -
On multicast beamforming and admission control for UMTS-LTE
(2008)Transmit beamforming for physical layer multicasting is emerging as an appealing transmission modality for next-generation cellular wireless systems, notably UMTS-LTE. Optimal design of the transmit beamformer(s) from a ... -
Power detector based on voltage squaring
(2019)This paper presents a novel power detector using a voltage squaring circuit as power sensing element. The proposed solution features low power capabilities, extendable input range and low distortion. The circuit is designed ... -
Real time vision-based measurements for quality control of industrial rods on a moving conveyor
(2018)This work proposes a fully automated approach for vision-based quality control of manufactured metal rods. The proposed approach is able to detect the main axis of the rod and calculate its curvature, versus specifications. ... -
Resolving Loop Pipelining Issues in the CCC High-level Synthesis E-CAD Framework
(2018)Academic High-level Synthesis tools like CustomCoprocessorsCompiler have recently evolved in new versions with expanded functionality and more aggressive optimization schemes in order to satisfy hardware implementation ... -
Robust far-field spoken command recognition for home automation combining adaptation and multichannel processing
(2014)The paper presents our approach to speech-controlled home automation. We are focusing on the detection and recognition of spoken commands preceded by a key-phrase as recorded in a voice-enabled apartment by a set of multiple ... -
A second-order cone deflation approach to joint multiuser downlink beamforming and admission control
(2007)Multiuser downlink beamforming under quality of service (QoS) constraints has attracted considerable interest in recent years, because it is particularly appealing from a network operator's perspective (e.g., UMTS, 802.16e). ... -
Slice-based parallelization in HEVC encoding: Realizing the potential through efficient load balancing
(2017)The new video coding standard HEVC (High Efficiency Video Coding) offers the desired compression performance in the era of HDTV and UHDTV, as it achieves nearly 50% bit rate saving compared to H.264/AVC. To leverage the ... -
Sparse representations for hand gesture recognition
(2013)Dynamic recognition of gestures from video sequences is a challenging task due to the high variability in the characteristics of each gesture with respect to different individuals. In this work, we propose a novel ... -
A Sub-Sampling Approach for Data Acquisition in Gamma Ray Emission Tomography
(2016)State of the art data acquisition systems for small animal imaging gamma ray detectors often rely on free running Analog to Digital Converters (ADCs) and high density Field Programmable Gate Arrays (FPGA) devices for digital ... -
Visibility in the topology of complex networks
(2018)Taking its inspiration from the visibility algorithm, which was proposed by Lacasa et al. (2008) to convert a time-series into a complex network, this paper develops and proposes a novel expansion of this algorithm that ...
