Gao, Shibin (author), He, Zonglun (author), Wei, Xiaoguang (author), Liu, Y. (author), Huang, Tao (author), Lei, Jieyu (author)A topology attack, as a special class of false data injection attacks, tampers with topology information of a system to mislead the decision of the control center. This article conducts an in-depth study on topology attacks that aim to interfere with the judgment in topology information and pose potential damage by tampering with measurement...journal article 2022

Granello, P. (author), Soeiro, Thiago B. (author), van der Blij, N.H. (author), Bauer, P. (author)This article proposes an analytical methodology to evaluate the performance of the main partial power processing (PPP) architectures in terms of the improvements in the system's conversion efficiency. This analysis considers the influence of the system's voltage gain, the auxiliary dc/dc converter's efficiency, and the possibility of...journal article 2022

Granello, P. (author), Schirone, Luigi (author), Bauer, P. (author), Miceli, Rosario (author), Pellitteri, Filippo (author)The inherently intermittent nature of photovoltaic (PV) energy has brought increasing interest towards the integration between PV sources and Battery Energy Storage Systems (BESS). In this paper, a Series Partial Power Processing (PPP) converter based on Capacitive Power Transfer (CPT) is proposed to integrate PV and BESS in a grid-connected...conference paper 2022

Huang, Wen-Chin (author), Halpern, B.M. (author), Violeta, Lester Phillip (author), Scharenborg, O.E. (author), Toda, Tomoki (author)We present a voice conversion framework that converts normal speech into dysarthric speech while preserving the speaker identity. Such a framework is essential for (1) clinical decision making processes and alleviation of patient stress, (2) data augmentation for dysarthric speech recognition. This is an especially challenging task since the...conference paper 2022

(author)This paper presents a continuous-Time zoom ADC for audio applications. It combines a 4-bit noise-shaping coarse SAR ADC and a fine delta-sigma modulator with a tail-resistor linearized OTA for improved linearity, energy efficiency, and handling of out-of-band interferers compared to previous designs. In 160 nm CMOS, the prototype chip...conference paper 2022

Foosherian, Mina (author), Kernan Freire, S. (author), Niforatos, E. (author), Hribernik, Karl A. (author), Thoben, Klaus-Dieter (author)Conversational agents (CA) occasionally fail to understand the user's intention or respond inappropriately due to natural language complexity. These conversational breakdowns can happen because of low intent and entity prediction confidence scores. A promising repair strategy in such cases is that the CA proposes to users likely alternatives...conference paper 2022

Chen, P.Y. (author)This project proposes a different way of looking at AI alignment, namely by introducing AI Alignment Dialogues. We argue that alignment dialogues have a number of advantages in comparison to data-driven approaches, especially for behaviour support agents, which aim to support users in achieving their desired future behaviours rather than...conference paper 2022

(author)In this paper, we investigate several existing and a new state-of-the-art generative adversarial network-based (GAN) voice conversion method for enhancing dysarthric speech for improved dysarthric speech recognition. We compare key components of existing methods as part of a rigorous ablation study to find the most effective solution to...journal article 2022

(author)People of low literacy could benefit from automated support when learning about societal participation. We design an Embodied Conversational Agent (ECA) ‘coach’ that can provide effective learning support to low-literate learners, develop a prototype virtual learning environment, and evaluate this prototype with low-literate end users. First,...journal article 2022

Tsfasman, Maria (author), Fenech, Kristian (author), Tarvirdians, M. (author), Lorincz, Andras (author), Jonker, C.M. (author), Oertel, Catharine (author)When working in a group, it is essential to understand each other's viewpoints to increase group cohesion and meeting productivity. This can be challenging in teams: participants might be left misunderstood and the discussion could be going around in circles. To tackle this problem, previous research on group interactions has addressed topics...conference paper 2022

Bulygin, D. (author)In recent years, conversational agents (CAs) have been receiving more attention as tools for collecting data through qualitative interviews. The problem is we know little about how CAs affect both the interviewees and interviewers. This PhD project is dedicated to studying how to evaluate CA-mediated interviews and their effects on...conference paper 2022

Kernan Freire, S. (author), Niforatos, E. (author), Rusak, Z. (author), Aschenbrenner, D. (author), Bozzon, A. (author)Maintaining a complex system, such as a modern production line, is a knowledge-intensive task. Many firms use maintenance reports as a decision support tool. However, reports are often poor quality and tedious to compile. A Conversational User Interface (CUI) could streamline the reporting process by validating the user's input, eliciting...conference paper 2022

Ziar, H. (author)Incoming radiation energy illuminating a solar cell contains a certain amount of entropy, which does not contribute to output electrical work. Entropy has a different spectral distribution from the internal energy of light and consequently affects PV cell performance. Here in this work, we investigate the influence of entropy content of...journal article 2022
