Prepositioning relief network is an effective strategy to mitigate the impact of natural disasters and public health emergencies, such as the ongoing COVID-19 pandemic. However, designing a proper network is challenging due to limited information and, more importantly, the spatially correlated...

This paper investigates single machine scheduling problems with release time and random processing time, where the release time can be either deterministic or random. The objective is to determine a scheduling sequence that performs well in terms of out-of-sample performance. To achieve this, we...

Low-cost and eco-friendly auxiliary energy supply units to power gas sensors are of great significance to various fields. In this work, a gas sensor based on the PANI/NiCo 2 O 4 composite was powered by a gelatin-polyimide based triboelectric nanogenerator (GP-TENG) for the detection of NH 3 at...

In recent years, flexible wearable sensors have attracted great research interest in the fields of human movement monitoring, medical health monitoring, and artificial electronic skin. With the rapid development of wearable devices, the requirement for sensors with high sensitivity and wide...
