A Fuzzy Control Irrigation System For Cottonfield [PDF]

open access: yes, 2009
A fuzzy control irrigation system for cotton field is presented in this paper. The system is composed of host computer, slave computer controller, communication module, soil water sensors, valve controllers, and system software. A fuzzy control model is constructed to control the irrigation time and irrigation quantity for cotton filed.

Modeling and Control of Interacting Irrigation Channels [PDF]

open access: yes2019 IEEE 4th Colombian Conference on Automatic Control (CCAC), 2019
One of the most important activities in agriculture is irrigation, which has a high ecological impact and expends around 85$%$ of the freshwater that humanity consumes. In the irrigation process, most of the water is transported by networks of open-channel irrigation systems (OCIS) to each farmer.

From Rigid to Soft Robotic Approaches for Neuroendoscopy

open access: yesAdvanced Robotics Research, EarlyView.
Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify

Optimization study of the fouling build-up on a RO membrane for pretrated olive mill wastewater purification [PDF]

open access: yes, 2017
Even though membranes are considered in many aspects a mature technology, a range of features are still in development and under investigation. Regarding this, the main handicap of this technology is inevitably membrane fouling.

Multi‐Enzyme Mimetic Molybdenum Nitride Nanozymes Reshape Subgingival Microenvironment for Synergistic Periodontitis Therapy via ROS Regulation and Microbiome Remodeling

open access: yesAdvanced Science, EarlyView.
ABSTRACT Periodontitis, a chronic inflammatory disease initiated and sustained by plaque microorganisms and host immune response, remains an intractable oral disease and a leading cause of tooth loss worldwide. Traditional mechanical debridement and adjunctive antibiotic or antiseptic therapy often shows limited efficacy due to the complex anatomical ...

Design an intelligent controller for full vehicle nonlinear active suspension systems [PDF]

open access: yes, 2011
The main objective of designed the controller for a vehicle suspension system is to reduce the discomfort sensed by passengers which arises from road roughness and to increase the ride handling associated with the pitching and rolling movements.

Diversity of Pharmaceuticals Enhances Antibiotic Resistance in the Invertebrate Gut via Biofilm‐Mediated Mechanisms

open access: yesAdvanced Science, EarlyView.
Pharmaceutical diversity acts as an independent driver of antibiotic resistance in soil invertebrates. While bulk soil remains unaffected, the collembolan gut microbiome exhibits significant resistance gene enrichment under complex chemical exposure and diurnal warming.

Predictive control in irrigation canal operation [PDF]

open access: yesSMC'98 Conference Proceedings. 1998 IEEE International Conference on Systems, Man, and Cybernetics (Cat. No.98CH36218), 2002
Open canal dynamics in which a constant water level is kept at the bottom end of each canal pools by the upstream control structure of the pool are characterized by a time-varying delay associated with water transport. Predictive control, based on the output prediction over a long time horizon and the minimization of a quadratic cost function is ...
