Watching high quality videos anytime, anywhere is expected because mobile devices become popular. However, if mobile devices try to watch a video at the same time via a wireless network, the concentrated loads to delivery server cause a delay and a stop of playing videos on client devices. Therefore, in this paper, we realize a mobile video on demand delivery system that mobile devices can watch high quality videos continuously by integrated methods of broadcast and communication. We delvelop the prototype system and have practical experiments to evaluate the proposed system.

In this paper, we evaluate performances of 4K/2K video streaming using DASH-JS over 2.4/5GHz WiFi networks. We confirmed that fluctuation of reception quality was mainly caused by the minimum representation rate of MPEG-DASH contents and overlapped ON cycles for packet transmission.

We have developed Body-Braille as an information transmission support tool for Deaf-Blind people. In this paper, improving the readability of Body-Braille is the goal. We investigated the optimal characteristics through two experiments. One is the reading of Body-Braille when produced by three types of motors, which are different in amplitude and frequency. The other is the reading of Body-Braille while changing the frequency with a fixed amplitude. As a result of the experiments, we revealed that the readability was influenced by both amplitude and frequency of the vibrator. Moreover we found that the optimal frequency band of the vibrator was in the range of 70Hz to 100Hz.

The System Wide Information Management (SWIM) concept is to change the conventional Air Traffic Management (ATM) information architecture from point-to-point data exchanges to system-wide interoperability. However, how to construct the local and global SWIM by applying Service Oriented Architecture (SOA) and Cloud based technologies is still under discussion. In this paper, the SWIM framework and SOA-based global SWIM construction through an international demonstration are presented.

This paper presents an Investigation regarding the performance of video and image encoders, when applied to the compression of surface electromyographic signals. In addition, a new preprocessing technique is introduced, called euclidean distance sorting (EDS), which has the potential to increase the exploitation of intersegment correlations. The experiments were carried out with real isometric records, which were first preprocessed and then compressed with the JPEG2000, H.264/AVC, and high efficiency video coding (HEVC) algorithms. It is clear that the proposed scheme is effective, given that the combination of EDS and JPEG2000 or HEVC even outperform state-of-the-art schemes present in the literature.

In this paper, we propose a method for detecting a specific object that has been determined in advance. Further, we aim to improve recognition accuracy by utilizing a super-resolution method to generate a high-resolution image from a low-resolution image. To achieve these goals, our proposed method employs a total variation regularization filter, a shock filter, and a pulse enhancement filter. The experimental results show that our method generates accurate high resolution images, and improves the accuracy of distant object detection.

We proposed a supporting system for location-based AR that enables user to handle virtual object without AR markers and hand mounting instruments. We also carried out design and implementation of the proposed system. It makes possible to calculate global coordinates of hands and recognize hand gestures through a combination of depth sensor, motion capture system, and head mounted display. To evaluate the performance of the proposed system, we carried out the taskes of moving, generating, and eliminating of virtual object. The recognition rates for all tasks are above 90%. Furthermore, because it is possible to handle virtual object with hand gestures by adopting depth sensor, the supporting system improved the disadvantages of AR marker method for location-based AR.

A dynamically reconfigurable system can perform complicated operations with dynamically changing the configuration. For ensuring the safety of the system, a model checking is one of the efficient formal approach.

In this paper, we propose a technique to decrease computational times in solving an integer linear programming (ILP) model for the static elevator operation problem (SEOP). The SEOP is a problem to optimally operate elevators on such assumption that all information on passengers who use an elevator system is known beforehand. In planning, there is a symmetry on elevators that exchanging 2 elevators does not affect the value of the objective function, if initial states of those elevators are identical. Such symmetry requires much computational times for problems to be solved, since there are at least 2 optimal solutions which differ only in allocations of elevators and partial solutions for those solutions can not be bound. That symmetry is resolved by giving different roles to elevators, and those roles are assignment pattern numbers (APNs) in the proposed technique. An APN of an elevator is a decimal number which is calculated from a binary vector which represents assignments of passengers to that elevator. The proposed technique deploys such a straightforward fact that all elevators have different APNs, and enfoces an elevator with a smaller index to have a smaller APN than other elevators with larger indexes. The effectiveness of that technique is numerically examined by applying a mathematical solver to ILP equations generated from some problem instances.

This paper proposes a procedural generation method that automatically creates game levels for Angry Birds, a famous mobile game, using genetic algorithm. By adjusting the parameters of the genetic algorithm according to the player's gameplay results, our proposed method can generate game levels that adapt to the player's skills. Our experiment proves that the proposed method is able to procedurally generate game levels that befit the player's skill.
