1. Vaginal Distention Rodent Model for Fecal Incontinence: A Pilot Study on the Effect on Defecation Behavior
Abstract Objectives Vaginal balloon inflation simulates the compressive forces on the pelvic floor during the second phase of natural delivery. The foremost use of this animal model of vaginal distention (VD) is to study the mechanisms underlying urinary incontinence. As damage to the pelvic floor during natural birth is a common cause of fecal incontinence

2. Total cholesterol/high-density lipoprotein and inflammatory parameters in patients with polycystic ovary syndrome
SUMMARY OBJECTIVE: In this study, the hormone profile, lipid profile, and inflammatory parameters of patients with polycystic ovary syndrome were compared with those of non-polycystic ovary syndrome patients to determine predictive markers in young polycystic ovary syndrome patients who have not yet had children. METHODS: Patients’ age, height, weight, b

3. A METHODOLOGY TO OBTAIN ANALYTICAL MODELS THAT REDUCE THE COMPUTATIONAL COMPLEXITY FACED IN REAL TIME IMPLEMENTATION OF NMPC CONTROLLERS
Abstract Model Predictive Control, MPC and NMPC, and real-time optimization, RTO and D-RTO, are known to help plant operability through the mitigation of impacts caused by external disturbances. However, the usage of these tools in industry requires overcoming some challenges, for instance: accurate models of the process, particularly in regard to nonlineari

6. Optimizing the Communication Capacity of a Ground Station Network
ABSTRACT: Small satellites are growing in use for educational, scientific, and commercial purposes, usually in Low Earth Orbit (LEO) flights, given their lower costs and associated risks, as well as smaller lead times for assembling and testing. However, the typically short periods of LEO passes bring the need to find ways of optimizing the communication bet

7. Research of the Photoelectric Tracking and Pointing Platform Based on the Servo Control System
ABSTRACT: To improve the speed and accuracy of the photoelectric tracking and pointing platform stable tracking, we took the three-axis photoelectric tracking platform, of which the coupling among the rings is ignored, as the research object. Considering the effects of various disturbances, the stable tracking double closed-loop servo control system was buil

8. A Hierarchical and Prioritized Framework in Coordinated Maneuver of Multiple Uavs Based on Guidance Regulator
ABSTRACT The structure of mission management and maneuver planning for multiple UAVs in close formation flight is investigated. This article provides a distributed and priority-based platform of guidance and control model to meet requirements for each coordinated maneuver. To accomplish the coordinated maneuvers of multiple UAVs, some levels of hierarchy fro

9. Stability Characteristics of a Model Trim Adjustment System for Open Loop Active Control of Thermoacoustic Instability
ABSTRACT Thermoacoustic instability in liquid rocket engines can have potentially catastrophic consequences. Active control based on feedback promises improved stability margin over a wider range of operating conditions than passive control. In the present work, the thermoacoustic characteristics of a trim adjustment active control system based on variable v

11. GPS Jamming Signals Propagation in Free-Space, Urban and Suburban Environments
ABSTRACT: GPS-based systems have been widely used in different critical sectors, including civilian, military and commercial applications. Despite of being able to provide great benefits, under certain circumstances they show to be highly vulnerable to intentional interferences. In this context, this article aimed to evaluate the vulnerability range of this

12. Hybrid Geoid Model: Theory and Application in Brazil
Determination of the ellipsoidal height by Global Navigation Satellite Systems (GNSS) is becoming better known and used for purposes of leveling with the aid of geoid models. However, the disadvantage of this method is the quality of the geoid models, which degrade heights and limit the application of the method. In order to provide better quality in transfo
