Advanced Materials Technologies, EarlyView.The impossibility of defining universal printability criteria for Direct Ink Writing (DIW) requires “unpacking” the process into printing subfunctions. Each of these is rationalized by identifying dimensionless groups, allowing effective comparison between the various material‐ and process‐related parameters for printability purposes.

DNA Code Design Based on the Bloch Quantum Chaos Algorithm
IEEE Access, 2017 The design of DNA codes sets satisfying certain combinatorial constraints is important in reducing hybridization errors due to nonspecific hybridization between distinct codes and their complements in DNA computing, data encryption, and data storage. The

On Expectation Correlate System and Chaotic Dynamics in Time-Series [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2004 This paper suggests a new system of time-series called Expectation Correlate System (ECS) that are good at detecting the behavior of dynamical systems (both deterministic and stochastic systems) and the dependence on initial values.

Multiparameter Closed‐Loop Control to Advance Reliability of Aerosol Jet Printing
Advanced Materials Technologies, EarlyView.A multiparameter framework for closed‐loop control of aerosol jet printing is developed to improve process consistency over both short and long timescales. By creating a control architecture responsive to the dynamic behavior of the printing system, variability in functional electrical properties is significantly reduced over extended duration printing,

Characterizing Extreme Events in a Fabry–Perot Laser with Optical Feedback
PhotonicsThe study of extreme events (EEs) in photonics has expanded significantly due to straightforward implementation conditions. EEs have not been discussed systematically, to the best of our knowledge, in the chaotic dynamics of a Fabry–Perot laser with ...
