Analysis and Research on Spatial Nodes of Historical Villages based on Spatial Syntax Theory: Cuiwei Village in Qianshan Area of Zhuhai as an Example

This research takes Cuiwei Village located in Qianshan District of Zhuhai City as an example. The village is investigated and analyzed through field research, and the street scale, spatial structure, functional characteristics of streets, internal commercial distribution forms, and functions in the Cuiwei Historic Block are studied and analyzed. Based on the convex space analysis method and the line of sight analysis method in the space syntax theory, with the help of the Depthmap software, the complex street nodes, that is, the space of the two nodes A and B analyzed. Through the establishment of a viewshed model, including the analysis of the viewport integration degree, the viewport agglomeration degree, the viewport connection value and the spatial characteristics of the historical area, the most representative traditional buildings in the village, namely the Sanwang Temple and the Weishi Mansion, are selected. =N and when the radius R=3, observe the changes of the two parameters, the integration of the visual field and the visual depth of the two historical buildings. And with the help of Baidu time machine photos in different periods to observe and record the store's changes and people's behavioural characteristics. The results show that: at the present stage, the coordination of villages is poor, people's recognition in the village space is weak, and people cannot use local perception to reflect the overall space. There are obvious sub-interfaces between the interior of the village and the outside world—good but poor global intelligibility. After an on-the-spot investigation and analysis, it can be seen that although people can walk out of Cuiwei Village, they are always in a state of confusion, and it is difficult to grasp the spatial form of the overall area. Therefore, the space syntax analysis results are consistent with the field survey results, so this research method has good reference value and reference significance in the study of village space.

Determining the Method of Predictive Maintenance for Aircraft Engine Using Machine Learning

Finally, the LSTM method is highly recommended while using with classify technique on ML to determine the PdM on an aircraft engine.

Electronic Document Management System (EDMS) Implementation: Implications for the Future of Digital Transformation in Philippine Healthcare

The COVID-19 pandemic is raising concerns all around the globe, as many lives have been lost and families have been left without hope. The Digital Era has started, and many sectors, including healthcare, are adapting to the innovative human-machine integration that has developed. However, the new systems still offer benefits and limits that will influence certain nations' choice to accept this platform owing to their unique requirements and circumstances. The earliest electronic health records were developed in the early 1960s to store long-term patient data. However, it was not maintained since the system's foundation is very demanding, and medical practitioners stopped utilizing it. After a decade, the growth of technology was unavoidable, gradually altering areas such as business and healthcare. However, every development has ramifications. The implementation of the new system may enhance organizational performance, but there are still uncertainties, notably about sustainability and how it will affect the firm in the future. Now, sufficient medical documentation has long been a source of contention in the healthcare industry, and management should begin introducing new processes to address the underlying problem. If the government already has a system in place to ensure the country's long-term existence, this system should be used to ensure the consistency of each patient's medical records. Will an Electronic Document Management System (EDMS) adaptation in the Philippines, a third-world nation with a poor healthcare system, be the best option to modify and enhance medical care quality?

Simulation and Implementation PID Controlling Buck Converter DC

Regulating the output voltage based on the desired set point is useful for many applications. However, getting the optimal value using fast computation with minimal error is still challenging. This paper aims to design, simulate, and implement a second-order Buck-Boost DC-DC converter circuit so that the voltage result according to the desired set point can be achieved. Initially, testing is conducted using Matlab Simulink. Then, Proteus is used to test the computation of the program on embedded systems in which the result is implemented in C. In low voltage power electronics applications, this approach has never been used to determine the output form. To determine the value of Kp, Ki, dan Kd, PID, Ziger Nichos (Guo, 2002). method is used. Meanwhile, tuning is done through Matlab. For simulation on Proteus, the output is tested by setting the setpoint values of 3.0, 2.5, and 1.7 volts. This aims to see the pattern of changes in the simulation. The simulation results with Proteus show that they have similar peak values but with different overshoot values. This is because the simulation must pass the reference voltage before it drops to the desired setpoint value. Proteus simulation can also help to prove embedded system programs are running correctly. On the other hand, the value of 1.7 volts is used as a setpoint in device implementation. This is due to the determination that the setpoint voltage in the implementation does not exceed the value of the source/power supply. The results show that for the rise time value of 378,770 ms, Overshoot and settling time are 11.798% and 0, respectively. This means the result produces an optimal value which is a return to the initial target. The optimal factor is assessed from the ability to minimize existing errors as well as having the shortest possible computational process.

Information System Engineering for Web-based RPS Adaptation using the Laravel Framework

Semester Learning Plan (RPS) is a learning planning document that guides lecturers and students to carry out lecture activities for one semester to achieve predetermined learning achievements. that the study program has been determined. RPS is needed to meet and adapt to users' needs because the RPS is regularly reviewed and updated if there are changes in teaching materials that are no longer under current conditions. However, what is often a problem is that the RPS input is still using Microsoft Excel, so that it is not well documented, and the RPS made are not following the material given by the lecturer. Because of these problems, in this study, a web-based RPS adjustment information system will be designed and built using the Laravel framework that can assist the study program in documenting the RPS and knowing the suitability of the material provided by the lecturer's predetermined RPS.

A Counseling System of Multiple Intelligence Theory Combined With kNN Classification Algorithm

Choosing the right career is always a big issue, an important concern for everyone. To have a job, which is suitable for you, firstly you must look at yourself, called the self, and you should be aware of what the self is then you can promote the strength of your own self and avoid your weakness. To help discover more about yourself, during researching and studying, we come up with the idea that we would propose a career counseling system based on Howard Gardner's theory. The system uses the theory of multiple intelligences (Abenti & Daradoumis, 2020) which is combined with the K-nearest neighbors (KNN) (Tang, Ying; Tang, Ying; Hare, Ryan; Wang, Fei-Yue;, 2020) algorithm to assist people and to give out a suitable suggestion about career path for them. We use the results of the eight intelligences retrieved from the KNN classification algorithm to give users the consulting for their career paths. This system is built with a dataset based on 56 multiple-choice questions. These include 48 multiple choice questions based on Howard Gardner's theory of multiple intelligences (Bravo, Leonardo Emiro Contreras; Molano, Jose Ignacio Rodriguez; Trujillo, Edwin Rivas, 2020), (businessballs, 2017) and 8 multiple choice questions which are the labels of the classifier. We divided the dataset into 8 subsets corresponding with 8 Intelligences defined by Howard Gardner with the collected dataset. In each subset, we build the KNN classifier model using KNN classification algorithm. This processing of 8 subsets come out with the results accuracy for the 8 Intelligences: linguistic intelligence (80.95%), logical-mathematical intelligence (82.14%), musical intelligence (96.43%), bodily-kinesthetic intelligence (82.14%), spatial-visual intelligence (82.14%), interpersonal intelligence (89.29%), intrapersonal intelligence (88.1%), existential intelligence (78.57%). With the outcome of 8 models, we have tested with 5 students and compared them to their actual intelligences. The comparison results tell us about the valuable potential in career path of the proposed counselling system, the advantages of this combination between Multiple Intelligence and KNN classifier.
