Formation of an Additional Motion Control Loop for the Nanosatellite to Adapt its Onboard Model to the Current Operating Conditions

The paper presents the formation of additional feedback in the loop of the attitude control system of a nanosatellite. Feedback is based on the assessment of the inertial characteristics of the nanosatellite. The influence of the accuracy of knowledge of the inertial characteristics of a nanosatellite on the formation of an optimal control law in the problem of reorientation was estimated. Statistical modelling has been carried out to assess the effectiveness of nanosatellite on-board sensors in the problem of identifying the inertial characteristics of a nanosatellite. Recommendations for the selection of sensor’s characteristics and time interval of data collection have been formulated.

Implementation of PI and MPC-Based Speed Controllers for a Drive with Elastic Coupling on a PLC Controller

This paper presents some of the issues related to the implementation of advanced control structures (PI controller with additional feedback, Model Predictive Controller) for drives with elastic coupling on a programmable logic controller (PLC). The predominant solutions to electric drive control include the use of rapid prototyping cards, signal processors or programmable matrices. Originally, PLC controllers were used to automate sequential processes, but for several years now, a trend related to their implementation for advanced control objects can be observed. This is mainly due to their compact design, immunity to disturbances and standard programming languages. The following chapters of the paper present the mathematical model of the drive and describe the implementation of the proposed control structures. A PI controller with additional feedback loops and a predictive controller are taken into consideration. Their impact on the CPU load was analysed, and the work was summarised by a comprehensive experimental study. The presented results confirm that it is possible to implement advanced control structures on a PLC controller for drives with elastic coupling while maintaining a sufficiently low load on its CPU.

Memristive Computation-Oriented Chaos and Dynamics Control

A variable boostable chaotic system and the Hindmarsh–Rose neuron model are applied for observing the dynamics revised by memristive computation. Nonlinearity hidden in a memristor makes a dynamic system prone to be chaos. Inherent dynamics in a dynamic system can be preserved in specific circumstances. Specifically, as an example, offset boosting in the original system is inherited in the derived memristive system, where the average value of the system variable is rescaled linearly by the offset booster. Additional feedback from memristive computation raises chaos, as a case, in the Hindmarsh–Rose neuron model the spiking behavior of membrane potential exhibits chaos with a relatively large parameter region of the memristor.

The association of standardized patient educators (ASPE) gynecological teaching associate (GTA) and male urogenital teaching associate (MUTA) standards of best practice

Gynecological Teaching Associates (GTAs) and Male Urogenital Teaching Associates (MUTAs) instruct healthcare professional learners to perform accurate and respectful breast, speculum, bimanual vaginal, rectal, urogenital, and prostate examinations. During such sessions, the GTA/MUTA uses their own body to instruct while providing real-time feedback. While GTAs/MUTAs fall under the broader umbrella of Standardized Patient methodology, the specificity of their role indicates need for establishment of Standards of Best Practice (SOBP) for GTA/MUTA programs. On behalf of the Association of Standardized Patient Educators (ASPE), the Delphi process was utilized to reach international consensus identifying the Practices that comprise the ASPE GTA/MUTA SOBP. The original ASPE SOBP was used as the foundation for the iterative series of three surveys. Results were presented at the ASPE 2019 conference for additional feedback. Fifteen participants from four countries completed the Delphi process. Four of the original ASPE SOBP Domains were validated for GTA/MUTA programs: Safe Work Environment, Instructional Session Development, Training GTAs/MUTAs, and Program Management. Principles and Practices were shaped, and in some instances created, to best fit the distinct needs of GTA/MUTA programs. The ASPE GTA/MUTA SOBP apply to programs that engage GTAs/MUTAs in formative instructional sessions with learners. Programs that incorporate GTAs/MUTAs in simulation roles or in summative assessment are encouraged to reference the ASPE SOBP in conjunction with this document. The SOBP are aspirational and should be used to shape Practices within the program’s local context. The ASPE GTA/MUTA SOBP will continue to evolve as our knowledge-base and practice develop.

Evaluating participants' experience of extended interaction with cutting-edge physics research through the PRiSE “research in schools” programme

Physics in schools is distinctly different from, and struggles to capture the excitement of, university research-level work. Initiatives where students engage in independent research linked to cutting-edge physics within their school over several months might help mitigate this, potentially facilitating the uptake of science in higher education. However, how such initiatives are best supported remains unclear and understudied. This paper evaluates a provision framework, Physics Research in School Environments (PRiSE), using survey data from participating 14–18-year-old students and their teachers to understand their experience of the programme. The results show that PRiSE appears to provide much more positive experiences than typical university outreach initiatives due to the nature of the opportunities afforded over several months, which schools would not be able to provide without external input. The intensive support offered is deemed necessary, with all elements appearing equally important. Based on additional feedback from independent researchers and engagement professionals, we also suggest the framework could be adopted at other institutions and applied to their own areas of scientific research, something which has already started to occur.

633 Use of an ICU Rounding Tool Enhances Critical Care Learning for Trainees on a Burn Surgery Rotation

Introduction An institutional Burn Intensive Care Unit (ICU) Rounding Tool was implemented for both quality improvement data collection and trainee education. Forms are completed by trainee team members daily for all critically ill patients prior to teaching rounds. Gathered data are structured to facilitate evaluation of patient volume status, sepsis risk and ventilator management. The forms are then used to guide discussion among students, residents, mid-level providers, fellows, attending surgeons and other members of the multi-disciplinary rounding team. We conducted a series of interviews with trainees regarding their user experience to assess the tool’s educational utility. Methods A convenience sample of residents who had recently completed their Burn Surgery rotation were interviewed in a structured format. Questions focused on the form’s ease of use and comprehensibility. Emphasis was placed on the extent to which it stimulates learning while rounding. Additional feedback was sought for the purpose of improving the tool for continued use. Results Participants were post-graduate year one or two resident physicians training in General Surgery, Urology, Emergency Medicine or Anesthesia. Prior experience and comfort with ICU level care ranged from very little to moderate. All interviewees found the tool helpful in their patient assessments, though the current layout of the form was a frustration for many. Overall, they unanimously found the forms beneficial for preparation of patient presentations and felt that utilization during rounds facilitated learning. Conclusions Interviews with trainees on their burn surgery rotation demonstrate that implementation of an ICU Rounding Tool has provided educational benefit, particularly for those less experienced in intensive care. Feedback from this cohort will be used to improve the tool’s usability. Our next steps will include a more formal survey of all trainees involved since the inception of this project.

FEM Based Study for Estimation of Applanation Force and Influence of Intraocular Pressure on Tonometry

Purpose: Excess force on cornea during eye care testing procedure such as tonometry may damage the internal structure of eye or may result in erroneous results. The proposed work can be utilized or incorporated as an additional feedback mechanism in the technology innovation of design of eye care instruments. Method: This work is focused on biomechanical simulation of human eye to determine applanation force on cornea and also to find the influence of intraocular pressure (IOP) of eye on Tonometry. Results: The results summarise that force applied by the tonometer will increase linearly for increase in deformation of cornea and the junction of cornea and sclera will undergo maximum deformation and hence will experience maximum stress compared to the centre of cornea where tonometer applanates the cornea. Conclusion: The tonometry will result in deformation of cornea in vertical elongation and the maximum stress is concentrated at the tonometer periphery as well as at the junction of cornea and sclera. The investigation also report that rise in IOP of eye demands higher force of applanation to get the prescribed deformation of cornea.
