The systematic kinematic analysis method for planar link mechanisms based on their unique procedures can clearly show the analysis process. The analysis procedure is expressed by a combination of many kinds of conversion functions proposed as the minimum calculation units for analyzing a part of the mechanism. When it is desired to perform this systematic kinematics analysis for a specific linkage mechanism, expert researchers can accomplish the analysis by searching for the procedure by themselves, however, it is difficult for non-expert users to find the procedure. This paper proposes the automatic procedure extraction algorithm for the systematic kinematic analysis of closed-loop planar link mechanisms. By limiting the types of conversion functions to only geometric calculations that are related to the two-link chain, the analysis procedure can be represented by only one type transformation function, and the procedure extraction algorithm can be described as a algorithm searching computable 2-link chain. The configuration of mechanism is described as the “LJ-matrix”, which shows the relationship of connections between links with pairs. The algorithm consists of four sub-processes, namely, “LJ-matrix generator”, “Solver process”, “Add-link process”, and “Over-constraint resolver”. Inputting the sketch of the mechanism into the proposed algorithm, it automatically extracts unique analysis procedure and generate a kinematic analysis program as a MATLAB code based on it. Several mechanisms are analyzed as examples to show the usefulness of the proposed method.

Error Optimization

In the motion of probing nanostructures, repeating position and movement is frequently happing and tolerance for position error is stringent. The consistency between the axis of manipulators and image is very significant since the visual servo is the most important tool in the automated manipulation. This paper proposed an automated axis alignment method for a nanomanipulator inside the SEM by recognizing the position of a closed-loop controlling the end-effector, which can characterize the relationship of these two axes, and then the rotation matrix can be calculated accordingly. The error of this method and its transfer function are also calculated to compare the iteration method and average method. The method in this paper can accelerate the process of axis alignment to avoid the electron beam induced deposition effect on the end tips. Experiment demonstration shows that it can achieve a 0.1-degree precision in 90 seconds.

Piso Surit dance in Karo community has distinctive characteristics in its movement techniques, floor patterns, environmental ethical norms, and symbolic-philosophical images. All of these characteristics grow and develop in line with aspects of the living environment that have been integrated in each form of art. This study aims to explain: 1) the basis and rules of Piso Surit dance; and 2) the concept of  Piso Surit dance choreography. This study uses a choreographic-anthropological approach, which is to analyze the relationship of dance motion with the aesthetic choreographic concept of Piso Surit dance and Karo community's mindset. Observation, documentation, and interview techniques are used to collect data and then the triangulation data analysis process is carried out to obtain the credibility of the data. The results showed that the rules for the use and application of motive motives fall into two categories, namely for male dancers and female dancers. The application of the prevailing floor pattern is dealing with their partners, side by side, and encircling each other. The rules for the use and application of accompaniment patterns intend to create a unified nature that is subtle, gentle, and harmonious. In the concept of choreography, Piso Surit's dance movements are broken down into nine (9) sections. The movements use techniques such as: a) tiptoeing, b) rotating movements, c) stopping fingers, and d) up and down movements. The music used as accompaniment in the Piso Surit dance is a folk song in Karo area with the same title. This dance uses 'beautiful' make-up to emphasize the dancer's facial lines in a dance performance, while the fashion is a dress code as used by Karo community. As a pair dance, the floor pattern applied is to show or emphasize the story of how young Karo young people combine love.

In this paper, a rolling mechanism constructed by a spatial 8-bar linkage is proposed. The eight links are connected with eight revolute joints, forming a single closed-loop with two degrees of freedom (DOF). By kinematic analysis, the mechanism can be deformed into planar parallelogram or spherical 4-bar mechanism (SFM) configuration. Furthermore, this mechanism can be folded onto a plane at its singularity positions. The rolling capability is analyzed based on the zero-moment-point (ZMP) theory. In the first configuration, the mechanism can roll along a straight line. In the second configuration, it can roll along a polygonal region and change its rolling direction. By alternatively choosing one of the two configurations, the mechanism has the capability to roll along any direction on the ground. Finally, a prototype was manufactured and some experiments were carried out to verify the functions of the mechanism.

Quality Of Research

Data analysis and mathematical techniques play a central role in quantitative data processing. Quantitative researchers estimate (strength) the strength of the relationship of variables, and test hypotheses statistically. Unlike the case with qualitative research. Although qualitative researchers might test a hypothesis in the analysis process, they do not estimate or test hypotheses about the relationship of variables statistically. Through tests or statistical tests can be used as the main means for interpreting the results of research data. It is through this statistical test that we as researchers can compare which data groups and what can be used to determine probabilities or possibilities that distinguish between groups based on an opportunity. Thus, it can provide evidence to determine the validity of a hypothesis or conclusion. In this study, we will discuss the preparation of data for analysis such as editing data, coding, categorizing, and entering data. As well as discussing the differences in data analysis for descriptive statistics and inferential statistics, differences in data analysis for parametric and non-parametric statistics in research, explanations of multivariate data analysis procedures, and also forms of research hypotheses.

Objective Score

The relationship of the perceptual trace to the objective score (raw score) under three practice conditions was the main concern of this study. Three groups of 14 Ss performed 35 trials on a stabilometer balancing task. Ss were asked to estimate how well they did after each trial. The difference between S's actual score and his guess was used as a measure of the perceptual trace. While performance and time estimations improved with practice, they correlated very low. The results were discussed in the context of Adams' closed-loop theory and gave mixed support for the theory.

Reason and the Qur'an know each other and are recognized in Islamic science. In this context, many researchers are interested in examining the relationship of reason and the Qur'an. According to Dr Muhammad Nahadi, discussion of reason, the Qur'an in the context of knowledge is the concept of developing knowledge. In line with this development, the development of Islamic education in the context of the study of reason and the Qur'an is urgently needed, especially as a means of answering the challenges of education with global challenges. This type of research is literature research, which is a form of scientific reasoning argumentation appearance that describes the results of literature studies and the results of the author's thought about a problem/topic of study. And data collection techniques using library research techniques, or library research, with data processing techniques. The data analysis process begins by gathering all data about the reason and objectives of Islamic education in order to find out the implications of reason in achieving the objectives of Islamic education. The results of this study indicate that, first, reason is the power of thought that when used can lead a person to understand and comprehend the problem he is thinking about. Second, reason serves as a tool for thinking, pondering and living also to develop ideas, concepts and bright ideas, very closely related to education. So that reason in its implications for the objectives of Islamic education is crucial to the
