Matrices are frequently decomposed in various ways in order to meet the conditions of an application, and therefore, algorithms for doing this are very important in the field of numerical linear algebra. In the tile algorithm, it is very critical to find a tile size that is suitable for the size of the matrix and the run-time environment. Smaller tiles can generate many fine-grained tasks. This can...
Oral presentation is considered as one of the most sought after skills by companies and professional organizations and program accreditation agencies. However, both learning process and evaluation of this skill are time demanding and complex tasks that need dedication and experience. Furthermore, the role of the instructor is fundamental during the presentation assessment. The instructor needs to...
Tile algorithms for matrix decomposition can generate many fine-grained tasks. Therefore, their suitability for processing with multicourse architecture has attracted much attention from the high-performance computing (HPC) community. Our implementation of tile QR decomposition for a cluster system has dynamic scheduling, OpenMP work- sharing, and other useful features. In this article, we discuss...
We implement the tile QR factorization algorithm on T2K open supercomputer using an OpenMP/MPI programming model. Our implementation does not outperform the ScaLAPACK routine for single-node performance. However, as the number of CPU nodes increases, our implementation clearly outperforms ScaLAPACK and shows good scalability in the form of both strong and weak scaling. With respect to accuracy, our...
Recently, a healthcare system utilizing electronic technology is attracting attention in the world. People are becoming increasingly conscious about health. Current healthcare services increase health awareness by providing information, but don't utilize the information. Moreover, medical service has problem of lacking the concept of prevention. For those problems, this research proposes a lifestyle...

The above results suggest the following fact; only if persons feel higher anxiety toward communication capacity of robots, their anxiety toward discourse with robots increases when the robot looks the other way during interaction with them, and decreases when the robot fixes the face. It means an interaction effect between a specific type of robot behavior and anxiety toward communication capacity...
To validate research question Q2, linear regression analysis for the scores of degrees of acceptability was performed for each context of robot activity. Table 1 shows the statistically significant regression models in the analyses. The results revealed that NARS-Emotion had statistically significant effects on acceptability, which we believe an interesting finding. Moreover, the existence of family...
