1. Research on Sliding Mode Method about Three-Dimensional Integrated Guidance and Control for Air-to-Ground Missile
ABSTRACT Based on adaptive sliding mode-control and back-stepping design method, an integrated guidance and control method with less calculation is proposed, which is designed for air-to-ground missile during the terminal course in three-dimensional space. The model of the control system with nonlinear and coupling is simplified, then the integrated guidance

2. Innate immunity and effector and regulatory mechanisms involved in allergic contact dermatitis
Abstract: Skin's innate immunity is the initial activator of immune response mechanisms, influencing the development of adaptive immunity. Some contact allergens are detected by Toll-like receptors (TLRs) and inflammasome NLR3. Keratinocytes participate in innate immunity and, in addition to functioning as an anatomical barrier, secrete cytokines, such as TN

3. Wound healing treatment by high frequency ultrasound, microcurrent, and combined therapy modifies the immune response in rats
BACKGROUND: Therapeutic high-frequency ultrasound, microcurrent, and a combination of the two have been used as potential interventions in the soft tissue healing process, but little is known about their effect on the immune system. OBJECTIVE: To evaluate the effects of therapeutic high frequency ultrasound, microcurrent, and the combined therapy of the

4. Tracking control of a planar five-link bipedal walking system with point contact, considering self-impact joint constraint by adaptive neural network method
AbstractIn order to achieve the practical characteristics of natural bipedal walking, a key feature is to realize "the straight knee state of walking" during stance and swing motions. Considering a straight knee necessitates that the shank link of each leg not to undergo the rotation angles which are greater than that of the thigh link. For this purpose, var

5. Local linear model tree and Neuro-Fuzzy system for modelling and control of an experimental pH neutralization process
This paper describes the modelling and control of a pH neutralization process using a Local Linear Model Tree (LOLIMOT) and an adaptive neuro-fuzzy inference system (ANFIS). The Direct and Inverse model building using LOLIMOT and ANFIS structures is described and compared. The direct and inverse models of the pH system are identified based on experimental da

6. Brain-computer interface: proposal of a shaping-based training
INTRODUCTION: Persons affected by certain motor disabilities such as amyotrophic lateral sclerosis can evolve with important motor and speech difficulties in communication. A BCI (Brain Computer Interface) is a system that allows interaction between the human brain and a computer, permitting the user to control a communication channel through his or her brai

7. Controle preditivo baseado em modelo neuro-fuzzy de sistemas não-lineares aplicado em sistema de refrigeração = : Model predictive control based on neuro-fuzzy nonlinear systems applied to a refrigeration plant / Model predictive control based on neuro-fuzzy nonlinear systems applied to a refrigeration plant
Refrigeration systems can be found in many different branches of industry and are characterized as great energy consumers with considerable non-linear behavior. Several studies have been developed to promote the reduction of energy costs and to minimize the effects of nonlinearities in these systems. The use of automation and process control, particularly th

8. Influência do Gene pacC na Regulação de Manosiltransferases no Dermatófito Trichophyton rubrum em Função de Variações Nutricionais e pH Ambiente. / Influence of Gene pacC in Mannosiltransferase Regulation of the Dermathophyte Trichophyton rubrum in Function to Changes by pH and Nutrient Sources.
Gene expression regulation is essential for fungi to adapt to environmental adversities, such as changes in the extracellular pH, nutrient starvation, ionic strength, and temperature. The adaptive response to ambient pH is well characterized in model fungi such as Aspergillus nidulans, and involves the signal transduction pathway consisting of the products o

9. Indirect adaptive predictive control applied to an industrial tank level plant
Predictive control algorithms have found growing acceptance in academic and industrial applications. However, as every control methodology, it has drawbacks, which is the need for an appropriate process model to be available. Therefore, the controller may become limited in applications with nonlinear and time-varying dynamics. When the predictions are not sa

10. Endothelial dysfunction in cardiovascular and endocrine-metabolic diseases: an update
The endothelium plays a vital role in maintaining circulatory homeostasis by the release of relaxing and contracting factors. Any change in this balance may result in a process known as endothelial dysfunction that leads to impaired control of vascular tone and contributes to the pathogenesis of some cardiovascular and endocrine/metabolic diseases. Reduced e

11. Aspectos nutricionais e buiquímicos da fibrose cística em paciente pediátricos : suplementação com um concentrado protéico do soro do leite bovino enriquecido com TGF- beta e lactoferrina / Nutritional and biochemical aspects of cystic fibrosis in pediatric patients : supplementation with whey protein concentrate enriched with TGF- beta and lactoferrin
Cystic fibrosis (CF) is characterized by an intense inflammatory process, pulmonary obstruction, airway infection and gastrointestinal symptoms resulting maldigestion/ malabsorption of nutrients, and as a consequence nutrition is a determinant on the patient`s prognostic. The aims were to evaluate the effect of supplementation with a WPC enriched with TGF-ß

12. Development, implementation and performance evaluation of a self-tuning regulator adaptive controller applied to a FCC process / Desenvolvimento, implementação e avaliação de desempenho de um controlador adaptativo do tipo self-tuning regulator aplicado a um processo FCC
This work had as main objective the development and implementation of an selftuning regulator (STR) adaptive controller, with subsequent comparison of its performance with a PID (proportional-integral-derivative) controller and two predictive controllers, namely a predictive based on artificial neural networks (MPC-ANN) and a dynamic matrix controller (DMC).
