A number of materials are delivered inside a hospital, and a fleet of autonomous navigating mobile robots are applied to replace these heavy mobility works. To increase the efficiency of using multiple robots, more than one delivery tasks can be assigned to a robot instead of delivering only one package at a time. This multi-task allocation algorithm (MTA) is introduced in this paper and a simulator is developed to measure the performance of the algorithm. The simulator models the hospital environment and enables to compare the delivery productivity by changing the number of robot. It shows that the efficiency of MTA increases dramatically compared to the single task allocation when using the same number of robot.

This paper proposes to verify the performance & error analysis of pedestrian indoor navigation system using commercially available low-cost inertial sensors. This self-contained approach employs Euler for attitude representation, where the estimation problem is formulated as an Extended Kalman filter (EKF) for INS strap down mechanization equations. The algorithm outputs are the foot kinematic parameters, which include foot orientation, position, velocity, acceleration, and stance phase. The approach is based on a zero-velocity update (ZUPT), Zero angular rate update (ZARU), Heuristic heading drift reduction (HDR) algorithms. The main contribution of the paper is to compare and analyse the heading drift reduction algorithms on Kalman-based IEZ platform and estimating the return position error. Orientation is then determined from the foot's initialized from accelerometer sensor information. Finally, we evaluated using experiments, including both short distance walking with different patterns and long distance walking performed in indoor.

MapReduce (MR) has been widely used to process distributed large data sets. Meanwhile, speculative execution is known as an approach for dealing with same problems by backing up those tasks running on a low performance machine to a higher one. In this paper, we have modified some pitfalls and taken heterogeneous environment into consideration. We also have implemented it in Hadoop-2.6 based on node classification, this strategy is called Speculation-NC and optimized Hadoop is called Hadoop-NC. Experiment results show that our method can correctly backup a task, improve the performance of MRV2 and decrease the execution time and resource consumption compared with traditional strategy.

Besides multiuser multi-input multi-output (MU-MIMO), non-orthogonal multiple access (NOMA) has been proposed as another promising alternative for multiuser multiplexing in cellular systems targetting for efficient spectrum utilization, and consequently has been attracting the attention of an increasing number of universities and institutes in both academic and industrial areas. In this paper, we focus on the azimuthal difference between the paired users, and investigate its influence on the system performance for both MU-MIMO and NOMA, respectively. The investigation reveals the different preference of the both schemes in respect of the inter-user azimuthal difference. Accordingly, a harmonized transmission framework for multiuser multiplexing has been proposed whereby the better transmission scheme of the both is always selected. Theoretical analysis justifies its effectiveness.

Through analyzing the storage system requirements of supercomputer this paper designs a near-line storage system called NLSS based on the combination of HDFS (Hadoop distributed file system) and ZFS (Zettabyte file system). NLSS uses fat storage nodes (large storage servers) to build near-line storage clusters based on HDFS, and uses the ZFS file system to further enhance HDFS. NLSS effectively reduces the burden of supercomputer online storage system. Experiment results show that NLSS can acquire better storage utilization, reliability and scalability while ensuring appropriate performance.

Cyber security awareness is an essential factor in today's world as the threat of cyber attack keep raising due to many individuals, organizations, and government institutions depend heavily on cyber infrastructure. This make it apparent as well that there is a need to establish a framework to enhance inter-organizational collaboration to achieve national cyber security awareness. This proposed study outlines a planned inquiry towards the investigation of that relationship specific to the context of Indonesian country. Through the use of semi-structured interviews and empirical evidences from relevant literatures, the expected outcome of this research is to find the relationship between inter-organizational knowledge sharing and the creation of cyber security awareness behavior.

These algorithms were developed to 2D and 3D spaces, WSN with fixed and mobile sensor nodes. The main goal of all of developed algorithms is the energy consumption decreasing and WSN life-time increasing. The new algorithms for clustering appeared during last time. These algorithms based on the idea of temporary cluster head using.

Using a wristband-type Photoplethymography (PPG) sensor, useful biomedical information such as heart rate and oxygen saturation can be acquired. Most of commercially-used wrist-type PPG sensors use green light reflections for its greater absorptivity of hemoglobin compared to other lights; this is important because wrists have comparably low concentration of blood flow. For reliable biomedical signal processing, we propose measurement sites for reflected red, green, infrared light PPG sensors on wrist. Amplitude, detection rate, and accuracy of heart rate are compared to determine the signal quality on measurement sites. Traditionally, wrist-type PPG sensors are implemented in measurement site 2, 3 or between 2 and 3 (between the distal Radius and the head of Ulna). Experiments show that all three reflected light PPG sensors generate good quality of PPG signals on measurement sites 4 and 11 (around the distal of Radius of left hand) in test subjects.

We are now facing a new age of digital content industry caused by diffusion of wearable device. The Realistic content, which consists of virtual reality, augmented reality and hologram technologies. It had been predicted as the future digital content technology by many institutions and researchers. However, there were very limited researchers who tried to predict the possibility of realistic content by analysing the user acceptance of realistic content technology. To analyse the intention of user acceptance, factors from three different perspectives were integrated with technology acceptance model to improve the reliability and validity of the research model and to give better results of analysis. Survey had been conducted by users in South Korea(N=429) who aware the existence of realistic content technology. Analysis was made based on structural equation modeling(SEM) method. The result of factor analysis showed that Flow and Spatiality have significant influence to Perceived usefulness. Interaction and Display have significant influence to the Perceived ease of use. Meanwhile users pointed out the Privacy risk as the most significant risk that avoid users to use the realistic content.
