1.Measuring Redundancy Score for Test Suite Evaluation by Using Test Cases Matching Approach
Mochamad Chandra Saputra, Tetsuro Katayama, Yoshihiro Kita, Hisaaki Yamaba, Kentaro Aburada, Naonobu Okazaki
Pages: 1 - 5
Evaluating a test suite that contains redundant test cases is necessary to reduce the cost of testing. The redundant test cases exist when both of the two test cases are executed the same lines of code. This research evaluates the test suite by identifying redundant test cases. Exact match approach is...

2.A Multi-agent Reinforcement Learning Method for Role Differentiation Using State Space Filters with Fluctuation Parameters
Masato Nagayoshi, Simon J. H. Elderton, Hisashi Tamaki
Pages: 6 - 9
Recently, there have been many studies on Multi-agent Reinforcement Learning (MARL) in which each autonomous agent obtains its own control rule by RL. Here, we hypothesize that different agents having individuality is more effective than uniform agents in terms of role differentiation in MARL. We have.

4.Generation of Cell-Like Images Using Euclidean Distance from Edge
Toru Hiraoka, Kohei Maeda
Pages: 14 - 17
A non-photorealistic rendering method has been proposed to generate cell-like images in which cell-like patterns are represented in photographic images. Cell-like patterns are automatically generated by the change of density of photographic images. However, cell-like patterns are irregularly arranged....

9.Design and Implementation of in-Home Real-Time Wireless Fever Monitoring in Pediatrics during the COVID-19 Pandemic
Ali S. Al-Mejrad
Pages: 37 - 40
Fever is one of the most common concern to be taken care by parents which sometimes force them to bring their children to the hospital emergency for continuous following up especially at night when sleeping. Fever is defined when the rectal temperature reaches over 38.0°C (100.4°F). Temperatures measured...

12.A Sub-Model Detachable Convolutional Neural Network
Ninnart Fuengfusin, Hakaru Tamukoh
Pages: 52 - 55
In this research, we propose a Convolutional Network with sub-Networks (CNSN), i.e., a Convolutional Neural Network (CNN) or base-model that can be divided into sub-models on demand. The CNN architecture, entails that feature map shapes are varied throughout the model, therefore, the hidden layer within...
