Exogenous Signals

Periodic exogenous signals often exist in motion systems, especially those involving one or more rotating elements. These periodic exogenous signals deteriorate the performance of motion systems, and these adverse effects cannot be practically eliminated by straightforwardly increasing feedback control gains due to sensor noise, actuator saturation, and unmodeled plant dynamics. This paper describes a sliding repetitive controller for motion systems subject to periodic exogenous signals. Moreover, an adaptive law for bound estimation is devised to ensure the presence of a sliding motion for both repetitive learning and disturbance observation. The tracking motion system of a disk drive is considered in practice, and a traditional repetitive controller is also implemented for performance comparisons with the proposed scheme. Experimental results are reported in this paper, showing the efficacy of the proposed scheme.

Injury prevention plays an important role in modern sport. The most commonly injured joint in male and female football players is the knee joint. It has been reported that approximately 60-85% of football injuries occur in the lower limbs. The aim of this study is to present the methods of biomechanical assessment of lower limbs joint loading during specific tasks (single leg squat (SLS) and single leg landing (SLL)). In this experimental setup, Qualisys Tracking Motion system synchronised with AMTII force plates embedded into the floor was used. The marker setup Salford Lower Limb model was used to track pelvis and lower body movements. By analysing biomechanical parameters (range of motion, internal moments, power, ground reaction forces) in all three planes it is possible to identify the structures and the imbalances of the lower extremity that need intervention and further decrease the possibility of injury to the knee and to evaluate an appropriate moment of return to play. This method showed a very high reproducibility and it can be considered as a reliable tool in assessing lower limb performance tasks.

This study aims to determine the effect of Problem Based Learning (PBL) model on higher-order thinking skills (HOTS) of Eleventh-grade students on motion system material in SMA Negeri 1 Indralaya Utara. The research method used was Quasi-Experimental with the research design of Non-equivalent Control Group Design. The sampling method used was Saturated Sampling Techniques. The instruments of data collection are HOTS test questions in the form of multiple choices with five answer choices in twenty-five questions. Observation instrument of learning implementation used Checklist with twelve observation items. The response instruments of students use questionnaires with a Likert scale. HOTS data were tested using the Mann-Whitney test, and then the learning implementation data and students’ response data were analyzed descriptively. This data processing uses SPSS twenty-three. Based on the results of the hypothesis test, the sig value is 0.00 (sig <0.05), which shows an effect studied was significant. The implementation of learning has Good Category, while the response of students has very good and good categories of the two types of the response of students measured. Based on the hypothesis test results can be concluded that the PBL’s model can significantly influence higher-order thinking skills of Eleventh-grade students on motion system material in SMA Negeri 1 Indralaya Utara.

Abstract Hoerl and McCormack demonstrate that although animals possess a sophisticated temporal updating system, there is no evidence that they also possess a temporal reasoning system. This important case study is directly related to the broader claim that although animals are manifestly capable of first-order (perceptually-based) relational reasoning, they lack the capacity for higher-order, role-based relational reasoning. We argue this distinction applies to all domains of cognition.

Lead Stearate

Among the ultra-light elements B, C, N, and O nitrogen is the most difficult element to deal with in the electron probe microanalyzer. This is mainly caused by the severe absorption that N-Kα radiation suffers in carbon which is abundantly present in the detection system (lead-stearate crystal, carbonaceous counter window). As a result the peak-to-background ratios for N-Kα measured with a conventional lead-stearate crystal can attain values well below unity in many binary nitrides . An additional complication can be caused by the presence of interfering higher-order reflections from the metal partner in the nitride specimen; notorious examples are elements such as Zr and Nb. In nitrides containing these elements is is virtually impossible to carry out an accurate background subtraction which becomes increasingly important with lower and lower peak-to-background ratios. The use of a synthetic multilayer crystal such as W/Si (2d-spacing 59.8 Å) can bring significant improvements in terms of both higher peak count rates as well as a strong suppression of higher-order reflections.
