Robust Feature Sets for Implementation of Classification Machines
Get PDFClassification Machines have evolved over a lot during recent times, in the field of engineering and sciences. Various classification schemes have been developed, taking into account, the aspect that can be optimized to give maximum system performance. The feature set in a classifier system is very significant, since it determines the efficiency and performance of the machine. Three powerful feature sets possessing robust classifying capabilities are discussed in this paper. Cepstral coefficient analysis based Kruskal-Wallis H statistic, F-test statistic and Discrete Sine Transform based features are found to be very effective for detection and classification of signals. Simulation results for typical data set are also presented in this paper. Statistical estimators, Neural Network and Hidden Markov Model based classifiers, along with various deep learning algorithms can be incorporated along with these feature sets to implement an efficient classifying machine. Typical results based on these feature sets are also presented for different signal sources.

Stock Management Optimization at IDUFASH Using an Android Based Application
Get PDFThe current technological advancements can be utilized by institutions for managing their inventory, including the use of information system technology. Institutions of various sizes, whether large, medium, or small, can harness this technology not only for data management but also for strategic maneuvering in response to business developments. Blink Evolution Store is one such clothing store that offers a variety of fashion products, including clothing, sweaters, hoodies, jackets, and pants. Manual record-keeping on paper consumes a significant amount of time, and inventory is not well-organized. With the advancement of information technology, there is a growing need for an application that can assist the Blink Evolution Store in efficiently managing and accessing goods data in a more organized manner. Using the waterfall methodology, the author can design the system sequentially, starting from the phase of Needs Analysis, system & software design, implementation & unit testing, integration & system testing, and ultimately concluding with operation & maintenance. The results of the blackbox testing on the IDUFASH application align with the initial system plan. In User Acceptance Testing (UAT) conducted using the Likert method, the author achieved a final testing score of 95.6%, which falls under the "highly satisfactory" category
Development of Android-Based Augmented Reality for Promotion of Jepara Tourist Attractions
Get PDFJepara Regency is an area rich in tourist attractions. By introducing tourist attractions to tourists who want to visit them, tourists will become more familiar with them and have the desire to visit them. Augmented reality is the technology of imaging virtual objects into the real world through a camera connected to a computer. The aim of this research is to implement augmented reality technology to increase the attractiveness of Jepara tourist attractions. Data was obtained through observation, interviews and documentation of tourists and the general public. By utilizing marker-based AR, promotion of Jepara tourist attractions can be clearly visualized and become effective introduction and information. This application can offer information on tourist attractions, accommodation and typical Jepara culinary delights. It is hoped that the development of promotional applications for Jepara tourist attractions can increase the attraction of tourists to visit Jepara and provide interesting experiences to visitors and have a positive impact on the regional economy and surrounding communities
Earthquake Readiness Analysis of Pamantasan ng Lungsod ng Maynila Students Using Simulation Application
Get PDFDespite the Philippines being recognized as a major need for enhanced disaster education and evacuation planning in every community, the ongoing pandemic has made it more difficult for institutions to execute required evacuation drills. As a result of a lack of repetition and participant involvement during mandatory earthquake simulations, participants overlook which routes are designated for evacuation and do not establish a lasting understanding of necessary procedures. Technology and gaming aspects may be used to simulate disasters for educational purposes. The Earthquake Simulation Application, which is based on a model of the structures around the Pamantasan ng Lungsod ng Maynila, was tested on a group of university students to confirm that the system complies with the standards outlined in ISO 25010. The purpose of the Earthquake Simulation Application created in this study is to advise students of the appropriate actions to take during and after an earthquake. To prevent unfavorable results, there are features that inform users of what constitutes incorrect behavior. This earthquake application repeatedly simulates the events that occur during an earthquake to support the retention of correct evacuation routes. Most responders who got earthquake simulation application instructions were able to fail the procedure at least once, but few were able to complete it. It was established that the earthquake simulation program was exceptional in terms of both functional stability and usability, as well as performance
Codeless Test Automation for Development QA
Get PDFCodeless test and testing automation promise to make the software testing process and, by extension, the software development Quality Assurance (QA) process easier and more streamlined. It naturally resonates with agile development/testing methodology, which requires repeated and in-development testing, and conventional testing practices and test automation are too time-consuming and resource-intensive (dedicated testers) for most development teams. Codeless testing tools can be used for different testing phases (unit to acceptance testing), and even though certain challenges still remain, they are rapidly being resolved with the development of more sophisticated tools. Technologies like Artificial Intelligence (AI) and good practices like cross-functional tools and shared test libraries can make codeless testing a standard part of development QA
Acetone Adsorption to Co3O4?111?Surface: A Density Functional Theory (DFT) Study
Get PDFAcetone, as one of VOCs, is not only polluting to the environment, but also harmful to humans. Therefore, detecting acetone is an important topic in the field of gas sensing. The carbonyl functional group determines the chemical properties of acetone. Aldehydes also contain carbonyl functional group. In this paper, we have calculated adsorption energy, adsorption distance and transfer charge by DFT. The results showed that the top of Co3+ on Co3O4 (111) surface has the best selectivity for sensing acetone. Our study contributes to the further study of the sensing properties of p-type metal oxide semiconductor sensors
Environmental Degradation 1s Degradation in Language and Culture
Get PDFThis paper investigates the impact of environmental degradation on the communicative capacity of language. Basing its analysis on L?mnso’ idioms, the paper establishes with a lot of scientific rigour, that the extra-linguistic and sociological variables found in the data under consideration, contribute to the process of signifying or generating meaning in language. It principally reveals that degradation in geographical environment reduces the communicative potential of language both at the denotative and connotative levels. In addition, adducing very fresh and dependable evidence, it establishes that language is intrinsically linked to environment and culture. It very exciting contributions lie in its stress on this hither to neglected aspect of linguistic studies – that is, the relevance of geographical environment to the generation of meaning and effective communication in language and, in its revelation that game reserves and forest reserves should not only be used as touristic sites, but also as language, and cultural laboratories
