  • In our previous study, the small-sized quasi-servo valve using two inexpensive on/off valves was developed and tested. The pressure control type quasi-servo valve was also proposed and tested by using the quasi-servo valve, a pressure sensor and an embedded controller. In this paper, the pressure control type quasi-servo valve is applied to a force control of the pneumatic cylinder, and its control performance is investigated.

  • During robot-assisted laparoscopic radical prostatectomy (RALP), steep Trendelenburg position and carbon dioxide pneumoperitoneum are inevitable for surgical exposure, both of which can impair cardiopulmonary function. This study was aimed to compare the effects of pressure-controlled ventilation with volume guarantee (PCV with VG) and 1:1 equal ratio ventilation (ERV) on oxygenation, respiratory mechanics and hemodynamics during RALP.

  • Lactation starts with active contraction of the myoepithelial cells surrounding the alveoli, this process is termed milk ejection, or milk let down. These myoepithelial cells contract when stimulated by oxytocin, a hormone released from the neurohypophysis of the pituitary as a result of a neuro-endocrine reflex. The afferent side of the reflex consists of sensory nerves from the mammary glands, particularly the nipples or teats. Afferent information reaches the hypothalamus, which regulates the release of oxytocin from the neurohypophysis.

  • Pest and disease management continues to be an important challenge to the agricultural community. Confronted with the shifts in pest pressure and the rise in new pest and crop problems, coupled with public concern over pesticide use and more stringent environmental regulations, today’s crop producer must exhibit good stewardship and stay current with new technologies in order to produce high-quality crops in a profitable manner.

  • The main objective of this thesis is to comprehensively investigate the control of moisture in above-grade enclosure walls. Increasing the understanding of the interaction of the wind, rain, and building enclosure is of special interest. Masonry veneer wall systems will be a focus of the study because of their wide-spread use. As discussed above, pressure moderation and ventilation of the air space are two little understood components of moisture movement in walls and thus will also be given emphasis.

  • The employed method is easy to implement in practical applications and moreover, the SMC exhibits the desired dynamic properties during the entire output-tracking process independent of perturbations. Simulation results are presented to demonstrate the effectiveness of the proposed controller in terms of performance, robustness, and stability. Results show that the proposed controller for the load following operation is so effective that the xenon oscillations are kept bounded in the given region.

  • Apple (Malus × domestica) is an important fruit crop cultivated worldwide. Apple orchards are exposed to a diverse set of environmental and biological factors that affect the productivity and sustainability of the apple cultivation. Many of the efforts for apple production rely on reducing the incidence of fungal diseases, and one of the main diseases is apple scab caused by the fungus Venturia inaequalis (Cooke) Wint. Apple scab is the most devastating important disease of cultivated apple causing economic losses in terms of fruit quality and yield in many apple growing areas.

  • Lumbar spinal stenosis (LSS) is frequently associated with postural instability. Although several studies evaluated patients’ functional impairments, underlying sensorimotor mechanisms are still poorly understood. We aimed to assess the specific set of postural control deficits associated with LSS during spontaneous and externally perturbed stance and evaluated post-surgical changes in postural behavior.

  • Knee osteoarthritis (OA) negatively affects dynamic postural control, which is a basic function that individuals use to perform activities of daily living (ADL). The purpose of this study was to investigate the associations of center of pressure (COP) control during the transition from double-leg to single-leg standing with subjective assessments of ADL and quality of life (QOL) in patients with knee OA.

  • Process plants consist of hundreds, or even thousands, of control loops all networked together to produce a product to be offered for sale. Each of these control loops is designed to keep some important process variable such as pressure, flow, level, temperature, etc. within a required operating range to ensure the quality of the end product. Each of these loops receives and internally creates disturbances that detrimentally affect the process variable, and interaction from other loops in the network provides disturbances that influence the process variable....

  • On March 20, 1905, a disastrous boiler explosion occurred in a shoe factory in Brockton, Massachusetts, killing 58 persons, injuring 117 others, and causing a quarter of a million dollars in property damage. For years prior to 1905, boiler explosions had been regarded as either an inevitable evil or “an act of God” (see Figs. 1.1 and 1.2).

  • Diesel engines, also known as CI engines, possess a wide field of applications as energy converters because of their higher efficiency. However, diesel engines are a major source of NOX and particulate matter (PM) emissions. Because of its importance, five chapters in this book have been devoted to the formulation and control of these pollutants. The world is currently experiencing an oil crisis. Gaseous fuels like natural gas, pure hydrogen gas, biomass-based and coke-based syngas can be considered as alternative fuels for diesel engines.

  • The search for oil occurs in geological sediments, as opposed to volcanic rocks. Several processes are involved in the creation of sediments. First, the inland continental volcanic rock is continuously being weakened and eroded by weathering processes (mechanical (through water, ice and wind) and chemical erosion). Secondly and simultaneously, the eroded material is being transported by water, ice and wind and gradually the material may be broken down into smaller pieces (from boulders to gravel, to sand, to silt and finally to clay).
