A dynamic model for control of GLCC liquid level and pressure using classical control techniques is developed in this paper for the first time. Detailed analysis of the GLCC control system stability and transient response indicates that liquid level control could be achieved effectively by a control valve in the liquid outlet for gas dominated systems or by a control valve in the gas outlet for liquid dominated systems. Based on the proposed linear control system model, the system performance is simulated using a suitable software design tool. The novel control system design approach presented in this paper forms a framework for the GLCC active control system optimization.P. 545 Keywords: liquid level, control valve, upstream oil & gas, controller, gas-liquid cylindrical cyclone separator, transfer function, drillstem/well testing, dynamic simulation, separation and treating, shoham Subjects: Well & Reservoir Surveillance and Monitoring, Processing Systems and Design, Formation Evaluation & Management, Information Management and Systems, Downhole and wellsite flow metering, Separation and treating, Drillstem/well testing This content is only available via PDF. 1998.

Dynamic Control Design and Simulation of Biogas Pressurized Water Scrubbing Process

<div class="htmlview paragraph">The purpose of dynamic modeling and simulation of Advanced Life Support (ALS) systems is to help design them. Static steady state systems analysis provides basic information and is necessary to guide dynamic modeling, but static analysis is not sufficient to design and compare systems. ALS systems must respond to external input variations and internal off-nominal behavior. Buffer sizing, resupply scheduling, failure response, and control system design are aspects of dynamic system design. We develop two dynamic mass flow models and use them in simulations to evaluate systems issues, optimize designs, and make system design trades. One model is of nitrogen leakage in the space station, the other is of a waste processor failure in a regenerative life support system.</div> <div class="htmlview paragraph">Most systems analyses are concerned with optimizing the cost/benefit of a system at its nominal steady-state operating point. ALS analysis must go beyond the static steady state to include dynamic system design. All life support systems exhibit behavior that varies over time. ALS systems must respond to equipment operating cycles, repair schedules, and occasional off-nominal behavior or malfunctions. Biological components, such as bioreactors, composters, and food plant growth chambers, usually have operating cycles or other complex time behavior. Buffer sizes, material stocks, and resupply rates determine dynamic system behavior and directly affect system mass and cost. Dynamic simulation is needed to avoid the extremes of costly over-design of buffers and material reserves or system failure due to insufficient buffers and lack of stored material.</div>

Strap-down inertial navigation system (SINS) is widely used in military field, to facilitate the study of SINS algorithms and various coupled navigation algorithms, a simulation system of SINS is designed. Based on modular design, with good portability and expansibility, the system consists of four independent modules: analysis module of motion state, trajectory simulator, IMU simulation module and SINS calculation module. With graphical interface, the system can control every motion state of the trajectory, which is convenient to generate various trajectories efficiently. Using rotation vector attitude algorithm to process simulation data, experiment results show that the attitude, velocity and position error is consistent with the theoretical value, which verifies the rationality of the simulation model and the availability of the simulation system.

Background: Simulation plays a fundamental role in the provision of healthcare education. It endows the trainees with a safe environment where they can develop, improve and sharpen their medical skills through continual and purposeful self-practice as well as constructive feedback. This study delves into the fundamental role simulators have with regard to educational theory and promotion of effective learning and to examine the effectiveness of a Ultrasound Interactive Console Simulator (USICS) relative to a Ultrasound Scanning Machine and to validate the functionality of the USICS. Method: This study’s core objective was to establish whether it is possible to implement an effective web-based distance education system that will facilitate users become fully acquainted with the elements and uses of an actual ultrasound instrument. Ultrasound Interactive Console Simulator (USICS) is an online application that was developed to enhance the learning effectiveness, which utilizes the qualities and supplies of the World Wide Web to build a significant learning atmosphere where learning is adopted and maintained. The participants were registered to enable them to use the system. During registration, the participants were given directions about the ultrasound simulation system’s basic functions and keys. There are two different methods in this study; one is a questionnaire that consist of eighteen multiple choices questions was used in the data collection of this study to investigate the similarity, the content effectiveness, construct validity, and easiness of usage. A Likert scale (1 - 5) was used to get the assessment from sonographer experts over the use of the USICS. After that we apply Cronbach's alpha test to test the face, content, construct validity. The other method is pretest and posttest experiments to examine that the USICS is a comparative effectiveness for learning factor. Paired T-Test was applied on this experiment. Results: Some of the important results found in this study were: • The results of operations performed by the USICS are similar to the other ultrasound machines such as the Philips Clear Vue machine. • There are no variations in the content effectiveness and construct validity between the simulator system (USICS) and the Philips Clear Vue machine. • The USICS is a useful and effective supplement to conduct training on a real-life Ultrasound Scanner. Conclusion: To facilitate the acquisition of technical skills as would be obtained from a generic Ultrasound scanning machine a simplistic perspective frames simulation was employed to endow the students with a safe and comprehensive alternative to conducting clinical procedures. It is firmly believed that the Ultrasound Interactive Console Simulator (USICS) aims to satisfy the growing demand for effective tools for online healthcare education and specifically in the area of Ultrasound scanning training. In a bid to strike the right balance in the simulation of an ideal clinical scenario it is imperative to align the simulator in a way that replicates clinical environment in that is authentic and realistic. The results from the use of USICS indeed seem to meet this need and hold much promise for other and in-depth ventures into similar online healthcare training applications.

This article addresses the design and development of a computer-based medical simulation system (NeuroCath) for training and patient-specific planning of interventional neuroradiology procedures. NeuroCath includes three main components: vascular extraction and modeling, instrument navigational simulations, and realistic human-computer interfaces. As the basis of the simulation, the vascular model is constructed from images obtained from different modalities such as X-ray, magnetic resonance imaging, and computerized tomography data. The model takes into account topological, geometrical, and physical properties of the patient’s vasculature. A finite element method–based physical model is constructed to simulate the behavior of interventional radiological instruments and devices within vessels during the interventional radiology processes. Realistic human-computer interfaces are provided in accordance with the actual interventional radiology environment. These interfaces include the video monitors displaying the simulated X-ray images and the haptic apparatus providing physicians with realistic tactile feedback encountered in the catheterization procedures.

In order to solve the problems of traditional basketball classroom teaching, a virtual simulation system for students' sports training is designed. Firstly, a sports capture system is set up to collect information and compare it with a standard database to judge the irregularities of athletes' movements, and then the athletes' movements are digitized and the skills are improved statistically in combination with the system functions. The human body model diagram is constructed and the characters are designed to obtain the virtual basketball stadium and the technical action virtual simulation results of the basketball players. Then, the motion capture technology is used to track the motion tracks of key information nodes in the virtual simulation results to obtain the motion tracks of leg bones in the training process of the basketball players. The system is conducive to acquiring knowledge and skills, realizing effective organization and management of teaching and training information, and providing a good learning and training environment for teaching and training.

Welcome to the historic, vibrant and beautiful city of Edinburgh. Scotland's capital is imbued with a rich tradition of creativity, design, innovation and research, making it a most fitting home for the 12th ACM SIGCHI Designing Interactive Systems (DIS'17) conference. Running biennially since 1995, the Designing Interactive Systems (DIS) Conference is the premier, international arena where designers, artists, psychologists, user experience researchers, systems engineers, and many more, come together to debate and shape the future of interactive systems design and practice. DIS is owned by the ACM Special Interest Group on Computer- Human Interaction (SIGCHI). In the past, DIS has been held in Ann Arbor (1995), Amsterdam (1997), New York (2000), London (2002), Boston (2004), State College (2006), Cape Town (2008), Aarhus (2010), Newcastle (2012), Vancouver (2014), Brisbane (2016) and now, in 2017, moves to a new era of annual conferences. The DIS'17 conference schedule starts with two days of pre-conference workshops and a doctoral consortium and continues with three main conference days into which we have packed 130 peer reviewed paper and pictorial presentations into 30 sessions across three parallel tracks, alongside which we have demos, provocations and works in progress, a lunchtime symposium held by Facebook and two invited keynote speakers. The social program includes a welcome reception on Sunday evening, a Demos & Posters Industry Reception on Monday night, the DIS conference dinner on Tuesday night, and a post-conference closing drinks party on Wednesday night. The theme of DIS 2017 is bridging and connecting -- across disciplines, practices, places and understandings. The most interesting things happen at edges and boundaries, and so the aim of the 2017 conference is to examine different approaches to framing knowledge about the design of interactive systems. As advancements in interactive technology continue to blur the demarcations between people and data, and between things and software, interaction designers and researchers are finding new ways to explore this evolving, interdisciplinary landscape. At DIS 2017 we shall consider the contrasts and commonalities that are central in shaping the landscape of emerging interaction paradigms. I am very proud that we have been able to curate and assemble a stellar program, including two invited keynote presentations by Salvatore Iaconesi (ISIA Design Florence) and Di Mainstone (QMU), I am sure they and the program will encourage much thought, discussion and future endeavours.

At the background of the development of a marine electric propulsion system(EPS) training simulation system, the components and operation condition of the EPS are introduced. The design and implement of hardware and software are presented. Mathematical models of the main equipments which suit for real-time simulation are established, and the method of getting equipment parameters without original product data is proposed. At last, the conclusion is that this scheme is quite suitable for mid-sized systems for its feasibility of programming and developing.

Shaking table tests on a dynamic interaction system of hard layered soil, pile foundation and frame structure were carried out. The earthquake damage of the superstructure and foundation was reproduced. Based on these tests, several key issues about the seismic response of the dynamic soil-structure interaction (SSI) system were studied. The natural frequency of the system was less than that of the structure on rigid foundation if the SSI is not taken into account, while its damping ratio was larger than that of the structure. The mode shape of the system was different from that of the structure on the fixed base in that there were rocking and swinging at the foundation. Magnification or reduction of vibration transferred by soil was related to soil characteristic, excitation magnitude, and so on. Generally, sand magnifies vibration, while viscous powder soil dampens vibration. The components of the acceleration response at the top of the superstructure were based on the relative magnitude of the rocking stiffness, the swing stiffness of the foundation and the stiffness of the super-structure. The multi-direction excitations have little effect on the key issues of the horizontal SSI.

A traffic signal system established due to the congestion of vehicles at road intersections. Traffic choking at road convergence becomes a controversy for daily riders and proportionally allowing the violation of traffic rules or other hazards. The conventional traffic signal system has lots of disadvantages. Even the system is automatic but due to fixed time range it gives rise to other problem like traffic violation, air pollution indirectly this would lead to deceitful affair. The signal system has been executed using different types of controller some have fast execution time, a greater number of inputs and outputs, reliability also plays an important role in traffic signal system design. To overcome such issues, we proposed a design in this paper which works on the compactness of vehicles on traffic signals and also detects the traffic signal breach done by the vehicles. This paper shows the simulation of dynamic traffic signal and traffic breach control system with IR sensor or piezo sensor to detect the density of vehicles and traffic breach or jumping of red light. This paper related with an FPGA controller as a VLSI design using Verilog in Xilinx software.

The aim of this paper is to analyze different loss modeling methods for hydrostatic pumps and motors as an input for dynamic system simulation. Using dynamic simulation in an early design phase allows for optimization of driveline, driveline control and working hydraulic within several operating conditions. Using precise loss modeling methods enables prediction of energy consumption and energy losses over various duty cycles. Rising energy costs, enhanced government guidelines and increased environmental awareness require more efficient drive concepts especially in mobile working machines. Because of the complex machine structure with numerous hydraulic power consumers, like driveline, working, steering and braking hydraulic, dynamic system simulation is a need in the early design phase. This paper focuses on partial and full hydrostatic drivelines of mobile working machines which operate mostly on basis of a closed circuit hydrostatic transmission. Hydrostatic power lines connect pump and motor directly without additional losses because of valves or system characteristics. Therefore losses in the hydrostatic units have major relevance for the loss behavior of the hydrostatic transmission. The use of precise loss models is essential for analyzing hydrostatic transmission by means of dynamic system simulation. In the scope of this paper, one physical-empiric and four mathematical loss modeling methods are introduced, investigated and compared. Finally, the most promising modeling method is used for the simulation of a state of the art hydrostatic transmission.

In this paper, a study has been performed for optimal design and development of dynamic voltage compensation system using supercapacitor to solve voltage sag which are considered the dominant disturbances affecting power quality. Supercapacitor is employed to compensate dynamically for the voltage sag of system with sensitive load. With the prolific use of semiconductor devices in electrical equipment, modern-day loads are becoming increasingly sensitive to the sags and the disturbances prove to be costly to industries. As a technology -driven custom power installation, the dynamic voltage compensation system is recognized to be most effective equipment that can be used to counter the voltage sag problem. Hence, this paper proposes the high-performance optimal design of dynamic voltage compensation system which can efficiently compensate the instantaneous voltage sag and instantaneous interruption of the utility voltage source. This DVR system consists of a dynamic voltage converter in series with the supply voltage and high-efficiency controller of energy storage device using supercapacitor. Recently, in energy storage systems, the supercapacitor is paid attention as a new environmentally friendly energy storage element. This capacitor stores higher energy density than the conventional electrolytic capacitor. Also, this capacitor has a lot of advantages such as maintenance-free, longer life cycle and faster charge-discharge time than the conventional battery system. However, the supercapacitor for dynamic voltage compensation system must have each charge-discharge controller to control, a series-parallel switching circuit to use energy effectively with application of several compensation techniques for optimal operating. Therefore, in this paper, optimal development of on-line type dynamic voltage compensation systems is proposed.

At present, there is less software related to sport technical behavior recognition, and there are few studies on the classification and identification of detailed actions. By introducing computer technology to analyze the efficiency and regularity of sports, not only the characteristics of athletes can be excavated, but also the visibility and dynamic tracking of sport training can be provided. The process of sports education is a fast and complex systematic process. Through the interactive system of physical education, we can use different methods to collect sports data and make a comparative analysis of athletes’ movements. Through the data mining of the relationship between athletes’ physiological indexes and sports load, the unreasonable link in sports training can be avoided. Also, in sports training, we can use computer vision and modern biomechanics to construct a virtual sports education situation. With the classification accuracy as the fitness function, this paper collects the data through the network database, and returns the corresponding sport training parameters on this basis. The results showed that the accuracy of the model was nearly 98%, which met the actual demand. Therefore, the development of sports education assistant system can provide strong support for the process control of sports training and education.
