Crowd-Design: mapping of the crowd-based processes used by companies to develop products

Design e Tecnologia, 2017
From the term crowdsourcing, coined by Howe (2006), “crowd” prefixes appeared to nominate processes that occur through the Internet and with the crowd participation.

Automatic crowd density and motion analysis in airborne image sequences based on a probabilistic framework [PDF]

, 2011
Real-time monitoring of crowded regions has crucial importance to avoid overload of people in certain areas. Understanding behavioral dynamics of large people groups can also help to estimate future status of underground passages, public areas, or ...

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

Advanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Crowd-Sourcing a Way to Sustainable Urban Logistics: What Factors Influence Enterprises’ Willingness to Implement Crowd Logistics?

IEEE Access, 2020
The sharing economy has brought new opportunities to the logistics industry, which has created an emerging trend known as crowd logistics. Implementing this mode offers a basis for more sustainable urban logistics, but there is limited research on what ...

Glissile Interphase Boundaries Enable Collective Phase Switching in Epitaxial Polar Oxides

Advanced Functional Materials, EarlyView.
A triple point is identified in the phase diagram of low‐symmetry epitaxial BiFeO3 thin film along with an extended regime of phase competition associated with a flattened energy landscape. The electromechanical response is shown to be governed by correlated interphase‐boundary motion, including scale‐free avalanche dynamics characteristic of systems ...

A Realistic and New Approach for Crowd Density, Quantity, Types, and Anomaly Detection Using Effective Multi-Task Deep Learning Model

IEEE Access
Quantitative, type, and anomaly information in crowd videos is critical for smart city and campus applications. Existing approaches generally focus on high-performance counting or anomaly detection within the scope of crowd analysis.

Direction, Velocity, Merging Probabilities and Shape Descriptors for Crowd Behavior Analysis

IEEE Access, 2019
Descriptors are important for quantifying crowd behavior. The existing descriptors generally provide information about crowd density, i.e., number of people/objects present in a defined spatial area.

Electrically Induced Phase Transition and Synaptic Functionality in MoTe2/Graphene Memristors

Advanced Functional Materials, EarlyView.
An electrically induced reversible 2H ↔ 1T′ phase transition is demonstrated in a vertical Au/Ti/MoTe2/graphene memristor with a laterally contacted graphene electrode. Resistive switching proceeds through a compositionally invariant amorphous/2H ↔ amorphous/1T′ transformation, in which a self‐formed amorphous MoTe2 interfacial region is proposed to ...

Photorealistic Synthetic Crowds Simulation in Indoor Environments (PSCS-I): A Novel Synthetic Dataset for Realistic Simulation of Crowd Panic and Violence Behaviors

IEEE Access
Crowd analysis is a critical research field in computer vision that focuses on understanding and predicting crowd behaviors with applications extending to public safety, urban planning, and event management. However, the scarcity of large-scale, diverse,

Crowd Scene Analysis by Output Encoding

CoRR, 2020
Crowd scene analysis receives growing attention due to its wide applications. Grasping the accurate crowd location (rather than merely crowd count) is important for spatially identifying high-risk regions in congested scenes. In this paper, we propose a Compressed Sensing based Output Encoding (CSOE) scheme, which casts detecting pixel coordinates of ...
