Design and validation of a modular one-to-many actuator for a soft wearable exosuit

Xiloyannis, Michele; Annese, Eugenio; Canesi, Marco; Kodiyan, Anil; Bicchi, Antonio; Micera, Silvestro; Ajoudani, Arash; Masia, Lorenzo (2019)

The size, weight, and power consumption of soft wearable robots rapidly scale with their number of active degrees of freedom. While various underactuation strategies have been proposed, most of them impose hard constrains ...

Assessment of patients with negative symptoms of schizophrenia from movement, and prosodic and conversational speech signals

Chakraborty, Debsubhra; Yang, Zixu; Yasir, Tahir; Dauwels, Justin; Magnenat-Thalmann, Nadia; Tan, Bhing-Leet; Lee, Jimmy (2018)

Negative symptoms of schizophrenia are often characterized by speech and motor impairments. Therefore, in this paper we combine audio (prosody and conversation) and video (body movement) signals to distinguish patients ...

Effect of the surface charge of monodisperse particulate foulants on cake formation

Han, Qi; Li, Weiyi; Trinh, Thien An; Fane, Anthony G.; Chew, Jia Wei (2018)

In microfiltration and ultrafiltration, particulate foulants are inevitably deposited on the membrane surface, forming a cake whose structure and behaviour play crucial roles in the subsequent filterability of the suspensions. ...

Deep room recognition using inaudible echos

Song, Qun; Gu, Chaojie; Tan, Rui (2018)

Recent years have seen the increasing need of location awareness by mobile applications. This paper presents a room-level indoor localization approach based on the measured room’s echos in response to a two-millisecond ...

The effects of mixed carbon source on the competition between Polyphosphate Accumulating Organisms and Glycogen Accumulating Organisms under tropical climate

Wang, Li; Zhou, Yan (2018)

Summary of key findings 1. PAOs, cultivated with acetic or propionate acids, can uptake acetic acid, propionic acid, butyric acid, valeric acid and iso-butyric acid. 2. GAO, cultivated with acetic acid, can utilize ...

Distribution-based semi-supervised learning for activity recognition

Qian, Hangwei; Pan, Sinno Jialin; Miao, Chunyan (2019)

Supervised learning methods have been widely applied to activity recognition. The prevalent success of existing methods, however, has two crucial prerequisites: proper feature extraction and sufficient labeled training ...

Small-signal modeling, stability analysis, and controller design of grid-friendly power converters with virtual inertia and grid-forming capability

Deng, Han; Fang, Jingyang; Yu, Jiale; Tang, Yi; Debusschere, Vincent (2019)

Distributed virtual inertia provided by grid-friendly power converters is emerging as an effective way for inertia enhancement and frequency regulation improvement in more-electronics power systems. However, most existing ...

The metagenomics analysis of air, dust and surfaces of tropical buildings

Lau, Kenny Jia Xu; Uchida, Akira; Luhung, Irvan; Lim, Serene Boon Yuean; Schuster, Stephan Christoph (2018)

This study focuses on systematic comparisons between 3 types of samples (dust, air, surface) commonly analyzed in environmental quality studies for better understanding on the source-sink relationships among microbial ...

Context-based and explainable decision making with argumentation

Zeng, Zhiwei; Fan, Xiuyi; Miao, Chunyan; Leung, Cyril; Chin, Jing Jih; Ong, Yew Soon (2018)

Argumentation-based approaches to decision making have gained considerable research interest, due to their ability to select and justify decisions. In order to make better decisions, context is a key piece of information ...

MNPR : a framework for real-time expressive non-photorealistic rendering of 3D computer graphics

Montesdeoca, Santiago E.; Seah, Hock Soon; Semmo, Amir; Bénard, Pierre; Vergne, Romain; Thollot, Joëlle; Benvenuti, Davide (2018)

We propose a framework for expressive non-photorealistic rendering of 3D computer graphics: MNPR. Our work focuses on enabling stylization pipelines with a wide range of control, thereby covering the interaction spectrum ...

Two-stage stochastic scheduling of transportable energy storage systems for resilient distribution systems

Yao, Shuhan; Zhao, Tianyang; Zhang, Huajun; Wang, Peng; Goel, Lalit (2018)

Transportable energy storage systems (TESSs) provide critical flexibility to enhance the distribution system (DS) resilience. In this paper, a two-stage stochastic restoration scheme is proposed to minimize the total cost. ...

3D human motion recovery from a single video using dense spatio-temporal features with exemplar-based approach

Leong, Mei Chee; Lin, Feng; Lee, Yong Tsui (2019)

This study focuses on 3D human motion recovery from a sequence of video frames by using the exemplar-based approach. Conventionally, human pose tracking requires two stages: 1) estimating the 3D pose for a single frame, ...

A system for region search and exploration

Feng, Kaiyu; Zhao, Kaiqi; Liu, Yiding; Cong, Gao (2016)

With the increasing popularity of mobile devices and location based services, massive amount of geo-textual data (e.g., geo-tagged tweets) is being generated everyday. Compared with traditional spatial data, the textual ...

Antibody treatment against angiopoietin-like 4 reduces pulmonary edema and injury in secondary pneumococcal pneumonia
