Structure evolving systems and control in integrated design [PDF]

, 2008
Existing methods in Systems and Control deal predominantly with Fixed Systems, that have been designed in the past, and for which the control design has to be performed. The new paradigm of Structure Evolving Systems (SES), expresses a new form of system

Performance Triggered Adaptive Model Reduction for Soil Moisture Estimation in Precision Irrigation

International Journal of Adaptive Control and Signal Processing, EarlyView.
ABSTRACT Accurate soil moisture information is essential for precise irrigation to enhance water use efficiency. Estimating soil moisture based on limited soil moisture sensors is especially critical for obtaining comprehensive soil moisture information when dealing with large‐scale agricultural fields.

Hyperoxia Induced Alteration of Chromatin Structure in Human Bone Marrow Derived Primary Mesenchymal Stromal Cells

Advanced Biology, EarlyView.
Chromatin, which organizes DNA, changes its structure to adapt to stress like high oxygen levels (hyperoxia), which can damage cells. Researchers developed a technique to observe these changes and found variability in how different parts of chromatin remodel.

A study of two stochastic search methods for structural control [PDF]

, 2003
: Many engineering tasks involve the search for good solutions among many possibilities. In most cases, tasks are too complex to be modeled completely and their solution spaces often contain local minima.

Investigation on the quench sensitivity during isothermal treatment of a high Mg-containing Al–Mg–Zn–Si alloy

Journal of Materials Research and Technology
In this study, the quench sensitivity of a novel high Mg-containing Al–Mg–Zn–Si alloy was investigated using an isothermal treatment process. The electrical conductivity in the quenched state and the hardness in the aged state of the alloy were measured,
