The supercavitation weapon is a new concept weapon moving at a high speed underwater, which is devised applying the characteristic of supercavitation reducing the resistance of water, and it may be widely used in the future. The present ventilating system has many shortcomings, such as less automation and numerous data cannot be measured and recorded timely. In this paper, the automatic monitor and control ventilating system of supercavitation water-tunnel was developed using configuration software and PLC. All parameters can be measured, recorded and displayed automatically via using of the system. It has many advantages such as higher automation, convenience, and easy maintenance.

Wind and solar energy are considered as the most representatively new and renewable energy. At present, wind and solar power generation systems is playing unique role in China's solar and wind energy resource-rich region, which arise more requirements to manage and monitor the system. Based on the MCGS (Monitor and Control Generated System) configuration software development platform, the monitoring system of experimental wind/solar hybrid system is designed, including controller driver loading, real-time database establishment, device configuration, animation production and other configuration. The developed software can better monitor and control the experimental wind/solar hybrid system.

This article presents a hybrid validation technique to test mathematical models and control systems for a High Speed Supercavitating Vehicle HSSV. The test method combines simulation of the vehicle motion, real-time experimental measurements of hydrodynamic forces acting at the vehicle wetted areas, and vehicle flight computer to evaluate the HSSV performance subject to steady and unsteady flows. The proposed validation platform is deployed in the high speed water tunnel located at the University of Minnesota Saint Anthony Falls Laboratory SAFL. The supercavitating test vehicle, operated with ventilation, consists of an actuated disk cavitator and two actuated lateral wedge fins. The model of the vehicle motion, used to develop the validation platform and design HSSV controllers, is derived through experimental data obtained in the high speed water tunnel. An illustration is given on how the control system is able to track pitch angle reference commands and reject flow perturbations produced by an oscillating foil gust generator.

Abstract Background Africa contributed to one-third of the world’s neonatal mortality burden. In the Sub-Saharan region, preterm birth complications are the leading, in which a neonate is a higher risk of developing respiratory distress syndrome that will require extra oxygen and help with breathing. When compared to other respiratory supportive methods for treating infants in respiratory distress, bubble continuous positive air pressure (CPAP) is a safe, and effective system that is appealing to many resource-limited neonatal units in low and middle income countries. However, despite of its benefit, the accumulation of condensate in the patient's circuit's exhalation limb during a bubble CPAP can significantly increase pressure delivered to the serious physical consequences that can potentially lead to respiratory failure. Currently, existing technology in developing nations is expensive, and they will not control the accumulation of condensate in the exhalation limb. This quietly increases the mortality rate of neonates. Therefore, the objective of this project was to design, and develop a bubble CPAP device that able to monitor and control pressure delivered to the infant. Methods In this project, a low-cost bubble CPAP machine with a pressure monitoring and controlling system has been developed. When the neonate expires, the pressure sensor inserted into the expiratory tube reads the instant positive end expiratory pressure (PEEP) and sends it to the microcontroller. The microcontroller decides whether to turn the relay (controls the electric power to the 2 - solenoid valve) to switch the way of expiration between the two expiratory tubes connected to the valves of two outlets. This depends on the pressure reading and the cutoff pressure value manually inserted by the physician. Results The prototype was built and subjected to various tests and iterations to determine the device's effectiveness. The developed prototype was tested for accuracy, safety, cost, ease of use, and durability. The prototype was accurate in 10 iterations that had been made to monitor and control the pressure. It was safe and provided accurate pressure for the neonate, and it was built for less than 193 USD. Conclusion The proposed design allows physicians, especially those in low resource settings, to easily monitor and control the accumulation of condensate in the exhalation limb of the CPAP machine accurately and safely. This helps to reduce the neonate mortality rate that may occur due to respiratory distress syndrome.

ABSTRACTThis article analyses how the state in Senegal has managed the hajj since the liberalisation era in the early 2000s. Although the essence of the hajj is religious, it is also deeply political and requires that the state manages complex relations with pilgrims, religious leaders, private travel agencies, politicians and Saudi authorities. This article argues that three inter-related imperatives structure the conduct of the Senegalese state: a security imperative, a legitimation imperative, and a clientelistic imperative. Security concerns lead the state to monitor and control pilgrims travelling to Mecca. Legitimation is seen in the collaborative relations with Sûfi orders and in the framing of the hajj organisation as a ‘public service’. Finally, given the magnitude of financial and symbolic resources attached to the hajj, clientelistic relations are constitutive of state officials’ actions. Overall, despite the post-2000 liberalisation of the hajj, the state has maintained its role as a gatekeeper, regulator and supervisor.

(1) Background: Bioreactors mimic the natural environment of cells and tissues by providing a controlled micro-environment. However, their design is often expensive and complex. Herein, we have introduced the development of a low-cost compression bioreactor which enables the application of different mechanical stimulation regimes to in vitro tissue models and provides the information of applied stress and strain in real-time. (2) Methods: The compression bioreactor is designed using a mini-computer called Raspberry Pi, which is programmed to apply compressive deformation at various strains and frequencies, as well as to measure the force applied to the tissue constructs. Besides this, we have developed a mobile application connected to the bioreactor software to monitor, command, and control experiments via mobile devices. (3) Results: Cell viability results indicate that the newly designed compression bioreactor supports cell cultivation in a sterile environment without any contamination. The developed bioreactor software plots the experimental data of dynamic mechanical loading in a long-term manner, as well as stores them for further data processing. Following in vitro uniaxial compression conditioning of 3D in vitro cartilage models, chondrocyte cell migration was altered positively compared to static cultures. (4) Conclusion: The developed compression bioreactor can support the in vitro tissue model cultivation and monitor the experimental information with a low-cost controlling system and via mobile application. The highly customizable mold inside the cultivation chamber is a significant approach to solve the limited customization capability of the traditional bioreactors. Most importantly, the compression bioreactor prevents operator- and system-dependent variability between experiments by enabling a dynamic culture in a large volume for multiple numbers of in vitro tissue constructs.
