Optimal control for diffusions on graphs

, 2017
Starting from a unit mass on a vertex of a graph, we investigate the minimum number of "\emph{controlled diffusion}" steps needed to transport a constant mass $p$ outside of the ball of radius $n$.

Microwave‐Assisted Aqueous Synthesis of Gelatin‐Norbornene for Hydrogel Crosslinking and Bioprinting

Advanced Materials Technologies, EarlyView.
A microwave‐assisted reaction is utilized to synthesize gelatin‐norbornene (GelNB), achieving a high degree of norbornene functionalization while reducing the macromer's upper critical solution temperature. The resulting GelNB macromer has high solubility at room temperature, facilitating light‐based 3‐dimensional (3D) printing of thiol‐norbornene ...

Star formation thresholds and galaxy edges: why and where

, 2004
We study global star formation thresholds in the outer parts of galaxies by investigating the stability of disk galaxies embedded in dark halos. The disks are self-gravitating, contain metals and dust, and are exposed to UV radiation.

3D Printing of Stretchable, Compressible and Conductive Porous Polyurethane for Soft Robotics

Advanced Materials Technologies, EarlyView.
A 3D‐printable porous dopamine‐polyurethane acrylate elastomer results in conductive, stretchable, and compressible structures that can be metallized in situ through catechol‐mediated silver reduction. The resulting material function as both compliant soft robot with a and strain sensors without complex assemblies, enabling fully 3D‐printed soft ...

Tree Triple Exponential Smoothing Analysis in Forecasting of Fertilizer Sales

Acceleration, Quantum, Information Technology and Algorithm Journal
The majority of Indonesia's population relies on the agricultural sector, making fertilizer an essential raw material to increase productivity. PT. Pupuk Iskandar Muda (PIM), faces challenges in maintaining the balance of urea fertilizer production and demand. In 2021, PIM's urea fertilizer production was unable to meet demand, while in 2019, 2020, and

ChicGrasp: Imitation‐Learning‐Based Customized Dual‐Jaw Gripper Control for Manipulation of Delicate, Irregular Bio‐Products

Advanced Robotics Research, EarlyView.
Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

Chlorophyll-A Time Series Study on a Saline Mediterranean Lagoon: The Mar Menor Case

Engineering Proceedings
The Mar Menor, Europe’s largest saline lagoon, has experienced significant eutrophication. The concentration of chlorophyll-a (Chl-a) in the water is used as a critical indicator of this eutrophication process and can alert us to possible ecosystemic ...

Data‐Driven Bulldozer Blade Control for Autonomous Terrain Leveling

Advanced Robotics Research, EarlyView.
A simulation‐driven framework for autonomous bulldozer leveling is presented, combining high‐fidelity terramechanics simulation with a neural‐network‐based reduced‐order model. Gradient‐based optimization enables efficient, low‐level blade control that balances leveling quality and operation time.

Multi-agent Cooperative Caching Strategy Based on TD3 Algorithm [PDF]

Jisuanji gongcheng
To reduce content-acquisition delay and transmission overhead in mobile edge networks, a Multi-Agent Cooperative Caching algorithm(MACC) based on a Twin Delayed Deep Deterministic(TD3) policy gradient is proposed. First, a multi-agent edge cache model is
