Ringdown gravitational waves of compact binary mergers are an important target to test general relativity. The main components of the ringdown waveform after merger are black hole quasinormal modes. In general relativity, all multipolar quasinormal modes of a black hole should give the same values of black hole parameters. Although the observed binary black hole events so far are not significant enough to perform the test with ringdown gravitational waves, it is expected that the test will be achieved in third generation detectors. The Japanese gravitational wave detector KAGRA, called bKAGRA for the current configuration, has started observation, and discussions for the future upgrade plans have also started. In this study, we consider which KAGRA upgrade plan is the best to detect the subdominant quasinormal modes of black holes in the aim of testing general relativity. We use a numerical relativity waveform as injected signals that contains two multipolar modes and analyze each mode by matched filtering. Our results suggest that the plan FDSQZ, which improves the sensitivity of KAGRA for broad frequency range, is the most suitable configuration for black hole spectroscopy.

In the current industrial revolution, additive manufacturing (AM) embodies a promising technology that can enhance the effectiveness, adaptability, and competitiveness of supply chains (SCs). Moreover, it facilitates the development of distributed SCs, thereby enhancing product availability, inventory levels, and lead time. However, the wide adoption of AM in industrial SCs creates various challenges, leading to new difficulties for SC design. In this context, this paper proposes a new design approach to AM SCs using optimization methods. More specifically, the proposed approach, comprising the pmedian and mixed-integer linear programming models, considers the decision of deploying productive resources (3D printers) in specific locations of generic spare part SCs. The approach was evaluated in a real-world use case of an elevator maintenance service provider. The obtained results demonstrated the promising capabilities of the proposed design approach in managing the challenges arising from the forthcoming widespread use of 3D printers in manufacturing SCs. © 2020, CC-BY-NC-ND.

In the Philippines, the Civil Registry Documents (CRD) acquired from Philippine Statistics Authority (PSA) such as Birth Certificate, Marriage Certificate, Certificate of No Marriage and Death Certificate are being used as one of the requirements in different transactions in academics, government, travel, employment, religious matters and other transactions (e.g. proof of identification, Title/Career advancement, etc.). The current acquisition ways of these Civil Registry Documents are through online, PSA Office, Travel Agency/Courier Company and Satellite/Mobile PSA Office. In this study, the different acquisition ways of Civil Registry Documents are analyzed through service blueprint. Furthermore, a survey was conducted to determine the satisfaction rate and preferences of the CRD acquirers and was analyzed through crosstabulations. With the help of the analyzed Service Blueprints, the possible problems that arises on each process of acquisition were identified. This paper proposed an instant, electronic (involves bar coding/QR code/Reference number), paperless and less time-consuming substitute to the existing ways of acquiring Civil Registry Documents.

Various methods to predict stock prices have been studied. In a linked paper, we propose a stock price prediction method that applies DTW on scaled daily stock price patterns. We showed its performance using TOPIX data. In this paper, we further analyze the effectiveness of the proposed method using other price indexes, such as the S&P 500, CAC40, DAX, FTSE100, foreign exchange rates, and Cryptocurrency. This paper also reports the importance of pattern length and starting points of patterns. We also discuss the hidden behavior of investors which seems to explain the prediction ability of the proposed method. © 2018 The Institute of Electrical Engineers of Japan.

Japan Electronics and Information Technology Industries Association develops a puzzle-like programming game “Algologic” aiming to experience the concept of an algorithm for inexperienced programming learners. This is simple puzzle game aiming at solving a problem by automatically controlling a robot. The user designs an autonomous robot by selecting some of the instruction blocks, arranging the blocks in an appropriate order, and giving them to the robot. Before university students learn the basic of programming, with this programming puzzle game, we conducted a test to determine whether algorithms each student gave to the robot were correct or not. Likewise, after students have learned the basic of programming, we conducted a comprehension test to clarify the reachability. In this paper, we aim to investigate the relation between the comprehension of Algologic and the achievement degree of students after learning of programming and report the analysis result. Analysis results revealed that the results of Algologic test and the achievement results after learning programming were significantly in a positive relationship. © 2018 Newswood Limited.

The accuracy of the F statistic for structural health monitoring

Understanding the reliability of engineering methods is crucial for its adoption and deployment. This research focuses on the reliability of the Power Spectral Density (PSD) method via the use of the F statistic for damage detection. To the author best knowledge, the method is rather classic but its realibility has not been discussed in the context of a large data size. Priory, the research anticipates that the accuracy is a function of the damage level. In this study, we evaluate 3500 cases with five levels of structural integrity, namely, healthy condition and damaged conditions with 1%, 5%, 10%, and 20% damage levels. The dataset is established via a numerical analysis of a seven degree-of-freedom system loaded with a concentrated dynamic force with random magnitude. A spring on the system is reduced in its stiffness to simulate damages. Our significant findings are the following: it is challenging for the PSD-based method to differentiate the healthy condition from the damaged conditions when the damage level is small. However, the reliability is high at 95% probability when the structural integrity has dropped by five percent.

Numerical analysis of general-vibration-based method for structural health monitoring

For damage detection, this research article discusses an easy-to-compute damage index derived from the governing dynamic of the structure that has potential practical application in Structural Health Monitoring (SHM). The research uses simplified structural models to explore the sensitivity of the index to damages, to compare the index performance with a traditional but popular damage detection method, and to understand the local/global predictive capability of the index. The research uses two simple models, namely, single- and two-degree-of-freedom systems. The results suggest that the damage index is local, that can only monitor damages occurring near the points of measurements, but it is sensitive to damages, unlike the natural frequency, which is global but less sensitive.
