Abstract-This paper focuses on the enhanced initial centroids for the K-means algorithm. The original kmeans is using the random choice of init ial seeds which is a major limitation of the orig inal K-means algorith m because it produces less reliab le result of clustering the data. The enhanced method of the k-means algorith m includes the computation of the weighted mean to improve the centroids initializat ion. This paper shows the comparison between K-Means and the enhanced KMeans algorithm, and it proves that the new method of selecting initial seeds is better in terms of mathemat ical computation and reliability.
Purpose–The study aims to develop an application that will serve as an alternative learning tool for learning Asian Studies. The delivery of lessons into a virtual reality game dependson the pace of students. The developed application comprises several more features that enable users to get valuable information from an immersive environment.Method–The researchers used Rapid Application Development (RAD) in developing the application. It follows phases such as requirement planning, user design, construction, and cutover. Two sets of questionnaires were developed, one for the teachers and another for the students. Then, testing and evaluation were conducted through purposive sampling to select the respondents.Results–The application was overall rated as 3.56 which is verbally interpreted as very good. The result was based on the system evaluation using ISO 9126 in terms of functionality, usability, content, reliability, and performance. 476Conclusion–The developed application meets the objectives to provide an alternative learning tool for learning Asian Studies. The application is well commended and accepted by the end-users to provide an interactive and immersive environment for students to learn at their own pace. Recommendations–Further enhancement of the audio, gameplay, and graphics of the tool. Schools should take into consideration the adoption of the Asian Studies Virtual Reality as a good alternative tool for their teachers and students to teach and learn Asian Studies. The use of more 3D objects relevant to the given information to enhance game experience may be considered.A databank for the quiz questions that will be loaded into the game should also be considered.Research Implications–The integration of modern technology in education has been a vital part of the learning process, especially when technological resources are available. Development and adaptation of this application will promote an alternative way of independent learning among students and will give them a better understanding of Asian Studies at their own pace.
A new method of initializing centroids for Kmeans algorithm is developed in fixed asset monitoring application. The new method utilizing improved utilization of K-means using weighted average was found to be more efficient than the standard K-means owing to its simplicity and having no need for complex computation. The Depreciation was calculated with the use of the new method through the implementation of Age and Usage factors as the major attributes. The clustering output was able to determine the level of maintenance. This paper shows that the developed algorithm is highly applicable to accounting application. Index Terms-initialization of centroids, fixed asset, depreciation, level of maintenance
This study was conducted to design, develop and initially implement the Animal Identification and Records Monitoring Tool using RFID. Specifically, it identified the problems encountered in conducting Manual Tagging for Animal Clinic; the appropriate features of the tool that can be developed to address the problems encountered, and the respondents' level of acceptance of the user toward the developed tool in terms of functionality, reliability, usability, and performance. The problems encountered in conducting tagging for animal clinic were traditional animal tag may cause death to some animals; animal diseases and injuries by animal tagging; duplication and confusion in using animal tagging; and difficulty in maintaining records of vaccination, medication health check-ups using animal tagging.The appropriate features of the tool that can be developed to address the problems encountered were: RFID can make the process of animal tagging faster and easier; and online scheduling and identification of pets in pet clinics are more convenient to use for both pet owners and veterinarians rather than the manual process.The respondents' ratings for Animal Identification and Record Monitoring Tool using RFID were highly acceptable in terms of functionality (4.62); reliability (4.52); usability (4.68); and performance (4.59).The government agencies may suggest that animals should be tagged using the developed system for monitoring purposes. Further research on Internet controlled devices may be conducted other than stand-alone offline software programs. This study may also be developed considering the following features: UHF as a tracking device for animals; individual registered users to make page where the client can edit, rate and price; displaying hex value using LCD; access to the shop's system to be validated; contraction number of the project with logo and clinic's validation.
